Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is apparent that the specific embodiments described below are only some of the embodiments of the present invention, and that those skilled in the art will be able to practice the invention in other embodiments without the specific details.

The cellular communication network according to each embodiment of the present invention may be a global system for mobile communication (GSM) network, a Code Division Multiple Access (CDMA) network, a Wideband Code Division Multiple Access (WCDMA) network, a General Packet Radio Service (GPRS) network, a Long Term Evolution (LTE) network, an LTE Frequency Division Duplex (FDD) network, an LTE Time Division Duplex (TDD) network, a Universal Mobile Telecommunications System (UMTS) network, or the like. Correspondingly, the cellular communication device may be a base station (BTS) in GSM or CDMA, a Radio Network Controller (RNC) and a base station (nodeb) in WCDMA, an evolved node B (eNB or eNodeB) in LTE, and specifically, a macro base station (macro eNB) or a small base station (pico eNB) in LTE, or other wireless communication nodes with a coordination management function, such as a unified network controller (SRC), which is not limited in the embodiments of the present invention.

The non-cellular communication network may be a wireless local network (WLAN) using wireless fidelity (Wi-Fi) technology. The non-cellular communication device may be a WLAN Access Point (AP).

The user equipment in the embodiments of the present invention is supported for operation in both cellular and non-cellular communication networks. In a cellular communication network, user equipment may be referred to as mobile terminals (mobile terminals), mobile user equipment, etc. In a non-cellular communication network, a user equipment may also be referred to as a Station (STA). The user equipment may be a mobile phone (or referred to as "cellular" phone) and a computer with mobile terminal function, for example, a portable, pocket, hand-held, computer-embedded or vehicle-mounted mobile device, and the embodiment of the present invention is not limited thereto.

In various embodiments of the present invention, a user equipment that has successfully accessed a non-cellular communication device is referred to as an associated user equipment of the non-cellular communication device. The associated user equipment may be user equipment which opens a Wi-Fi function and directly accesses to the non-cellular communication equipment, or user equipment which successfully transfers service from the cellular communication network to the non-cellular communication equipment.

Fig. 1 is a schematic architecture diagram of a communication system 100 according to an embodiment of the present invention. As shown in fig. 1, the communication system 100 comprises at least one cellular communication device 101 providing cellular communication network coverage and at least one non-cellular communication device 102 providing non-cellular communication network coverage. At least one non-cellular communication device 102 may be deployed within the signal coverage of one cellular communication device 101. The traffic transfer of the user equipment may be a transfer of traffic at the cellular communication network to the non-cellular communication network, a transfer of traffic at the non-cellular communication network to the cellular communication network, or a transfer of traffic at the non-cellular communication network to another non-cellular network.

The technical problem mainly solved by the embodiments of the present invention is how to determine a traffic transfer threshold for a user equipment to perform traffic transfer from a cellular communication network to a non-cellular communication network. In the following embodiments, the service transfer performed by the user equipment refers to the user equipment transferring part or all of the service in the cellular communication network to the non-cellular communication network. In order to implement the service transfer of the user equipment, the user equipment may determine whether the service in the cellular network can be transferred to the non-cellular network according to a service transfer threshold for performing the service transfer. The traffic transfer threshold may include at least one of a loading threshold, a signal quality threshold of the user equipment (the signal quality threshold includes an uplink signal quality threshold of the user equipment and a downlink signal quality threshold of the user equipment), an available backhaul capacity threshold of the non-cellular communication device, an uplink and downlink traffic ratio threshold of the non-cellular communication device, an operating bandwidth threshold of the non-cellular communication device, and a packet error rate threshold of the non-cellular communication device.

It should be further noted that, in order to implement the communication between the user equipment and the communication system 100, fig. 1 further includes core network equipment, an Internet (Internet) server providing service content, and the like. When the cellular communication device 101 is a base station (e.g., eNB, BTS, BS, or the like), the base station and the core network device interact with each other through an S1 interface, the user equipment interacts with the cellular communication system 101 through an air interface, and the cellular communication system 101 interacts with each other through an X2 interface. When the cellular communication device 101 is an SRC, RNC or other wireless communication node with similar coordination management function, the cellular communication device 101 may control a base station (not shown) to coordinate with the non-cellular communication device 102, and the user equipment may interact with the cellular communication device 101 through the base station controlled by the cellular communication device 101 or the non-cellular communication device 102. The following embodiments can be distinguished as the case where the cellular communication device 101 is a base station and the cellular communication device 101 is an SRC, an RNC or other wireless communication node with similar coordination management functions. For the sake of brevity, the term cellular communication device is used uniformly.

Based on the communication system 100 shown in fig. 1, fig. 2 is a schematic flowchart of a method for determining a service transition threshold according to an aspect of the present invention. As shown in fig. 2, the method includes the following.

The cellular communication device 101 receives the performance information and the statistical information corresponding to the performance information sent by the non-cellular communication device 102.

The performance information sent by a non-cellular communication device and the statistical information corresponding to the performance information are one or more groups. The one or more sets may be transmitted by the non-cellular communication device at different times, possibly including the current time, or after a period of time of statistics.

202, the cellular communication device 101 determines a service transfer threshold for the user equipment to perform service transfer according to the performance information and the statistical information.

In 201 and 202, the performance information is an average transmission rate or an average access delay of the associated user equipment in the non-cellular communication device 102; the statistical information is at least one of a load of the non-cellular communication device 102, an uplink signal quality of the associated user device, a downlink signal quality of the associated user device, an available backhaul capacity of the non-cellular communication device 102, an uplink and downlink traffic proportion of the non-cellular communication device 102, an operating bandwidth of the non-cellular communication device, and a packet error rate of the non-cellular communication device 102.

The average transmission rate of the associated user equipment in the non-cellular communication equipment is the average of the uplink transmission rates of all the associated user equipment, the average of the downlink transmission rates of all the associated user equipment, or the total average transmission rate of the uplink transmission rates and the downlink transmission rates of all the associated user equipment in the statistical period. For example, the associated ue in the non-cellular communication device is ue a, ue B and ue C within a certain statistical period. The downlink transmission rates of the non-cellular communication device to the user equipment A, the user equipment B and the user equipment C are respectively 1Mbps (megabit per second), 2Mbps and 5 Mbps; the uplink transmission rates from the user equipment A, the user equipment B and the user equipment C to the non-cellular communication equipment are respectively 2Mbps,6Mbps and 4 Mbps. One possibility is that the average uplink transmission rate of the associated ue is (1+2+5)/3 ═ 2Mbps, and the average downlink transmission rate of the associated ue is (2+6+4)/3 ═ 4 Mbps. Another possibility is that the average transmission rate of the associated user equipment is 6Mbps for a total average transmission rate of 2+ 4.

The average access delay of the associated user equipment in the non-cellular communication equipment is the average uplink access delay and the average downlink access delay of all the associated user equipment counted by the non-cellular communication equipment in a counting period. The average uplink access delay is an average duration from backoff (backoff) start to backoff end of multiple packet transmissions of the associated ue within a statistical period. For example, the associated ue a transmits a data packet 5 times in a counting period, and the duration from the backoff start to the backoff end is 0.1ms (millisecond), 0.02ms,0.36ms,1.2ms and 0.8ms, respectively. The average uplink access delay of the user equipment a is (0.1+0.02+0.36+1.2+0.8)/5 ═ 0.496 ms. The average downlink access delay associated with the user equipment is the average duration of a plurality of times of packet transmission from the back-off start to the back-off end of the non-cellular communication equipment in a statistical period. It is particularly noted that the average downlink access delay associated with the UE refers to an average downlink access delay counted by the non-cellular communication device for all downlink data packets, and may also be a downlink average access delay counted by distinguishing downlink data packets of each UE. It should be noted that in the 802.11 standard, the uplink average access delay or the downlink average access delay of the associated ue may be referred to as a basic access set average access delay (BSSAverageAccessDelay). The non-cellular communication device broadcasts BSSAverageAccessDelay counted by the non-cellular communication device for all downlink data packets in a beacon (beacon) frame, so that the user equipment which is not associated with the non-cellular communication device knows the downlink average access delay of the non-cellular communication device.

The load of the non-cellular communication device includes: the number of associated user equipments, channel utilization (channel utilization), and available admission capacity (available admission capacity). Wherein, the channel utilization ratio is the proportion of the duration of the channel busy perceived by the non-cellular communication device to the observation time window. The available admission capacity refers to the remaining admission capacity of the non-cellular communication device 102, for example, the remaining admission capacity of the non-cellular communication device is 2Mbps, and if the required transmission rate of the user equipment is 4Mbps, the user equipment cannot be admitted to access the non-cellular communication device because the remaining admission capacity of the non-cellular communication device is less than 4 Mbps.

The uplink signal quality of the associated ue and the downlink signal quality of the associated ue both include RSSI (received signal strength indicator) or RCPI (received channel power indicator) or RSNI (received signal to noise indicator). The available backhaul capacity of the non-cellular communication device is the remaining transmission capacity of the wired link of the non-cellular communication device 102 to the internet server. The uplink and downlink traffic ratio of the non-cellular communication device is the number of data packets successfully received by the non-cellular communication device divided by the number of data packets successfully transmitted by the non-cellular communication device. The operating bandwidth of the non-cellular communication device includes, for example, IEEE802.11 b specifies that the non-cellular communication device can only operate at a bandwidth of 20MHz (megahertz), IEEE802.11n specifies that the non-cellular communication device can adaptively adjust the operating bandwidth to 20MHz or 40MHz, and IEEE802.11ac specifies that the non-cellular communication device can adaptively adjust the operating bandwidth to 20MHz, 40MHz or 80 MHz. The packet error rate of the non-cellular communication device includes an uplink packet error rate of the non-cellular communication device and a downlink packet error rate of the non-cellular communication device. The non-cellular communication device counts the downlink packet error rate, for example, the non-cellular communication device sends a downlink data packet, but does not receive the feedback of the user equipment within a specified time, and then the user equipment is considered to receive the packet error. The number of packet errors counted by the non-cellular communication device divided by the number of transmission times of the total downlink data packet may be used as the downlink packet error rate. The non-cellular communication device may count the downlink packet error rate for each ue accessing the non-cellular communication device, or the non-cellular communication device may count the downlink packet error rate for all ues accessing the non-cellular communication device. Similarly, the ue accessing the non-cellular communication device may count the uplink packet error rate and report the uplink packet error rate to the non-cellular communication device. The non-cellular communication device may perform arithmetic averaging on the uplink packet error rate reported by the user equipment. The non-cellular communication device may send the arithmetic mean of the uplink packet error rate and the downlink packet error rate to the cellular network access device, or may send the arithmetic mean of the uplink packet error rate and the downlink packet error rate to the cellular communication device as a packet error rate after averaging.

In 201, the cellular communication device 101 receives the performance information sent by the non-cellular communication device 102 and the statistical information of the cellular communication device corresponding to the performance information, which may include the following cases:

(1) the cellular communication device 101 and the non-cellular communication device 102 are integrated on the same physical device, also called co-sited.

In this case (1), the cellular communication device 101 receives the performance information and the statistical information transmitted by the non-cellular communication device 102 within the same physical device.

(2) The cellular communication device 101 and the non-cellular communication device 102 are not integrated on the same physical device, but the cellular communication device 101 has an Access Controller (AC) function of the non-cellular communication network.

In this case (2), the cellular communication device 101 and the non-cellular communication device 102 may employ a CAPWAP (wireless access point control) protocol to enable the cellular communication device 101 to receive performance information and statistics from the non-cellular communication device 102. Specifically, the non-cellular communication device 102 may discover the cellular communication device 101 and establish a CAPWAP tunnel in accordance with the auto-discovery function specified in the CAPWAP protocol. The cellular communication device 101 may receive the performance information and statistics sent by the non-cellular communication device 102 from the established CAPWAP tunnel.

(3) A new interface is established between the cellular communication device 101 and the non-cellular communication device 102.

In this case (3), the cellular communication device 101 and the non-cellular communication device 102 may establish an interface between the cellular communication device 101 and the non-cellular communication device 102 for transmitting the above-described performance information and statistical information in a request-response manner. For example, the user equipment searches for non-cellular communication devices using Wi-Fi technology, and the user equipment may send an identification of the searched non-cellular communication device 102, such as a Basic Service Set Identifier (BSSID), to the cellular communication device 102. The cellular communication device 102 inquires information such as the port number and address corresponding to the BSSID to the network management system. The cellular communication device 101 sends an interface establishment request to the non-cellular communication device 102 according to the queried port number and address of the non-cellular communication device 102, and when the non-cellular communication device 102 responds to the interface establishment request from the cellular communication device 101, the interface establishment between the cellular communication device 101 and the non-cellular communication device 102 is completed. The cellular communication device 101 may receive performance information and statistics from the non-cellular communication device 102 over the interface.

In 202, the cellular communication device 101 determines a service transfer threshold for the user equipment to perform service transfer according to the performance information and the statistical information, and in this embodiment of the present invention, two implementation manners may be generally adopted as follows:

(1) the cellular communication device 101 generates a corresponding relationship between the performance information and the statistical information according to the performance information and the statistical information, and selects statistical information meeting the performance requirement of the user equipment for service transfer from the corresponding relationship as a service transfer threshold for the user equipment to perform service transfer.

(2) The cellular communication device 101 generates a corresponding relationship between the performance information and the statistical information according to the performance information and the statistical information, and determines whether the performance information of the current statistical information of the non-cellular communication device 102 in the corresponding relationship meets the performance requirement of the user equipment for service transfer according to the corresponding relationship. If not, the cellular communication device 101 sets a service transfer threshold for the user equipment to perform service transfer to such a value that the user equipment does not satisfy the threshold for transferring service from the cellular communication network to the non-cellular communication network; alternatively, if so, the cellular communication device 101 sets the traffic transfer threshold to a threshold value that causes the user equipment to transfer traffic from the cellular communication network to the non-cellular communication network.

Optionally, after 202, the method further includes:

203, the cellular communication device 101 sends the service transfer threshold when the user equipment performs the service transfer to the user equipment. The user equipment may thereby determine whether traffic may be transferred from the cellular communication network to the non-cellular communication network based on the traffic transfer threshold. When the cellular communication device 101 is a base station, the cellular communication device 101 sends the service transfer threshold to the user equipment through an air interface, and when the cellular communication device 101 is an SRC, an RNC, or another wireless communication node with similar coordination management, the cellular communication device 101 forwards the service transfer threshold to the user equipment through the base station.

Optionally, in order to enable the ue to accurately identify which non-cellular communication device or non-cellular communication devices the Service transfer threshold corresponds to, the cellular communication device 101 may further issue, to the ue, an Identifier of the non-cellular communication device corresponding to the Service transfer threshold, for example, BSSID, SSID (Service Set Identifier), HESSID (homogeneous Extended Service Set Identifier).

In an embodiment of the invention, the cellular communication device 101 may receive the performance information and the statistical information from the at least one non-cellular communication device 102, and the cellular communication device 101 may generate the following correspondence, see table 1.

TABLE 1-A

In table 1, the non-cellular communication device i denotes an ith non-cellular communication device in the communication system 100, and the non-cellular communication device group i denotes an ith group of non-cellular communication devices composed of a plurality of non-cellular communication devices in the communication system 100. A non-cellular communication device i or a group of non-cellular communication devices i corresponds to M groups of performance information and statistical information, and A is used for average transmission rate/average transmission delay respectively transmitted_i1To A_iMIndicating that the loads transmitted respectively are B_i1To B_iMIndicating that the uplink signal quality of the respectively transmitted associated user equipments is C_i1To C_iMIndicating that the downlink signal quality of the respectively transmitted associated user equipments is D_i1To D_iMIndicating that the available backhaul capacity of the respective transmissions is E_i1To E_iMIndicating that the operating bandwidth of the respectively transmitting non-cellular communication device is F_i1To F_iMIndicating, separately transmittedPacket error rate G_i1To G_i1And (4) showing. The cellular communication device 101 may perform the service transfer according to the performance requirement of the ue, for example, the performance requirement of the ue is that the average transmission rate is a_i2Finding A in Table 1_i2The corresponding statistical information includes a load of B_i2Uplink signal quality of associated user equipment is C_i2The downlink signal quality of the associated user equipment is D_i2Backhaul capacity of non-cellular communication device is E_i2The operating bandwidth of the non-cellular communication device is F_i2Packet error rate of G_i2. The cellular communication device 101 may determine the load threshold as load threshold B_i2The uplink signal quality threshold of the user equipment is C_i2The downlink signal quality threshold of the user equipment is D_i2The remaining backhaul capacity threshold of the non-cellular communication device is E_i2The threshold of the working bandwidth of the non-cellular communication equipment is F_i2With a packet error rate threshold of G_i2. The cellular communication device 101 may issue the plurality of traffic transition thresholds to the user equipment.

It should be noted that the above-described manner of determining the multiple traffic transition thresholds may not be accurate. In order to achieve the best user experience, the cellular communication device may be based on one of the statistics and assisted by the other statistics in determining the traffic transition threshold. For example, in order to set the load threshold, the cellular communication device 101 finds one or more loads corresponding to the required performance in table 1 according to whether the average transmission rate indicated by the required performance is greater than a certain value or the average transmission delay is less than a certain value when the user equipment performs the traffic transfer. An alternative is that the cellular communication device directly issues the corresponding one or more loads as load thresholds to the user equipment, so that the user equipment can transfer the service to the non-cellular access device corresponding to the one or more loads. Since there may be a plurality of loads in table 1 that satisfy the required performance, the cellular communication device may alternatively select one or more loads from the plurality of loads as the load threshold further according to the uplink signal quality of the associated user equipment, the downlink signal quality of the associated user equipment, the backhaul capacity of the non-cellular communication device, the operating bandwidth of the non-cellular communication device, the packet error rate, and the like. The principle of selection may be: associating the corresponding load of the user equipment with stronger downlink signal quality; associating a load corresponding to the user equipment having a higher uplink signal quality with a load corresponding to the non-cellular communication equipment having a higher remaining backhaul capacity; a corresponding load for a non-cellular access device having a greater operating bandwidth; at least one selection mode of the corresponding load with smaller packet error rate.

Further, it should be noted that, if the performance requirement indicated by the user equipment is that the average transmission rate is not less than a certain value, the cellular communication device may further determine, as the load threshold, a load corresponding to a smaller average transmission delay from the plurality of loads according to the average transmission delay received from the non-cellular access device. For example, as shown in Table 1-B.

TABLE 1-B

In table 1-B, non-cellular communication device i represents the ith of a plurality of non-cellular communication devices, which corresponds to multiple sets of performance information and statistics. In this example, the cellular communication device may determine the load threshold in accordance with Table 1-B. It is assumed that the performance requirement of the ue during traffic shifting is that the average transmission rate is not less than the average transmission rate i1, and the average transmission rate and the average transmission delay decrease sequentially from top to bottom in table 1-B. Since the average transmission rate i1 to the average transmission rate iM all satisfy the performance requirement, the cellular communication device may issue the loads i1 to iM, which are respectively corresponding to the average transmission rate i1 to the average transmission rate iM, as service transfer thresholds to the user equipment. Further, in order to set a reasonable service transition threshold for the user equipment, the cellular communication device may consider a load corresponding to a smaller average transmission delay and issue the load as a load threshold to the user equipment, for example, select a load corresponding to a smallest average transmission delay (average transmission delay iM) and issue the load as a load threshold to the user equipment.

It should be noted that, the performance requirement when the user equipment performs service transfer may be a performance requirement (usually stored in a core network device) that the cellular communication device acquires a performance requirement specified when the user equipment signs a contract with the non-cellular communication network; or the performance requirement when the cellular communication device performs service transfer from the user equipment received by the user equipment; or the cellular communication device by evaluating the historical average performance of the user equipment within the cellular communication device; or the cellular communication device estimating the performance that the user equipment may obtain in the cellular communication device in the future; it may also be that the cellular communication device sets a condition for the user equipment to be able to transfer traffic to the non-cellular network for the reason of reducing the load of the cellular communication network, in which condition the user equipment is easy to transfer traffic to the non-cellular network.

As an implementation, if the cellular communication device is to select a non-cellular communication network provided by the non-cellular communication device i or the non-cellular communication device group i as a target for user equipment traffic transfer, the cellular communication device 101 may employ at least one of the following modes of operation:

the load threshold is set as B_i2The uplink signal quality threshold of the associated user equipment is C_i2The downlink signal quality threshold of the associated user equipment is set as D_i2The backhaul capacity threshold of the non-cellular communication device is E_i2The threshold of the working bandwidth of the non-cellular communication equipment is F_i2With a packet error rate threshold of G_i2. Further, due to the adoption of the at least one operation mode, the user equipment may transfer the service to the non-cellular communication network provided by the non-cellular communication device i or the non-cellular communication device group i, but the non-cellular communication device i or the non-cellular communication device group i corresponding to the at least one operation mode may not be unique, and the cellular communication device may issue the identifier of the non-cellular communication device i or the non-cellular communication device group i to the user equipment for service transfer, so that the user equipment knows which non-cellular communication network or networks provided by the non-cellular communication device is/are subjected to service transfer.

As another implementation, the cellular communication device may determine whether the statistical information currently received by the non-cellular communication device meets the performance requirement of the user equipment during the service transfer. If the cellular communication device judges that the non-cellular communication device i or the non-cellular communication device group i does not meet the performance requirement of the user equipment for service transfer. The cellular communication device sets a service transfer threshold for the user equipment to perform service transfer such that the user equipment does not satisfy the threshold for performing service transfer from the cellular communication network to the non-cellular communication network. Or, if the non-cellular communication device i or the non-cellular communication device group i satisfies the performance requirement of the user equipment in service transfer, the cellular communication device 101 sets the service transfer threshold to a threshold value that allows the user equipment to certainly satisfy the service transfer from the cellular communication network to the non-cellular communication network.

Alternatively, the non-cellular communication device i or the non-cellular communication device group i may not currently be able to serve the user equipment due to the selection by the cellular communication device 101. Therefore, the user equipment may send the searched list of the non-cellular communication devices to the cellular communication device 101, and when the cellular communication device 101 determines that the list includes the non-cellular communication device i or the non-cellular communication device group i, the cellular communication device 101 issues a service transfer threshold corresponding to the non-cellular communication device i or the non-cellular communication device group i to the user equipment, so that the user equipment transfers the service to the non-cellular communication network provided by the non-cellular communication device i or the non-cellular communication device group i according to the service transfer threshold.

Based on the communication system 100 shown in fig. 1 and further details of the embodiment shown in fig. 2, fig. 3 is a flowchart illustrating a method for determining a service transition threshold according to an aspect of the present invention. In this embodiment, the non-cellular communication device is at least one WLAN AP. The cellular communication device and the at least one WLAN AP provide service to the user equipment. For convenience of illustration, the statistical information sent by the non-cellular communication device is the load of the at least one WLAN AP, the performance information of the non-cellular communication device is an average transmission rate or an average transmission delay of the associated user equipment in the at least one WLAN AP, and the traffic transfer threshold is a load threshold of the WLAN provided by the user equipment for transferring traffic to the at least one WLAN AP. As shown in fig. 3, the following is included.

301, the cellular communication device receives an average transmission rate or an average transmission delay of an associated user equipment, which is sent by at least one WLAN AP, and a load of the WLAN AP corresponding to the average transmission rate or the average transmission delay of the associated user equipment.

And 302, the cellular communication equipment determines a service transfer threshold for the user equipment to transfer the service according to the average transmission rate or the average transmission delay of the associated user equipment and the load.

As an implementation manner, the cellular communication device finds the load of the WLAN AP corresponding to the performance requirement according to the performance requirement for service transfer by the user equipment. The cellular communication device uses the load of the WLAN AP corresponding to the performance as a traffic transfer threshold.

As another implementation, the cellular communication device obtains a current load of at least one WLAN AP,

in 301, the cellular communication device may generate a correspondence between the average transmission rate of the associated user device and the load of the corresponding WLAN AP, see table 2.

TABLE 2

For illustration, in table 2, for the same WLAN AP i or the same WLAN AP group i, different loads correspond to the average transmission rate i1 to the average transmission rate iM. For convenience of illustration and example, it is assumed here that load i1< load i2< … < load iM, average transmission rate i1> average transmission rate i2> … > average transmission rate iM. As an example, the performance requirement of the ue during the traffic shifting is that the average transmission rate of the associated ue is not less than the average transmission rate i2, and the cellular communication device finds in table 2 that the average transmission rate of the associated ue is not less than the average transmission rate i2, which corresponds to the load i1 of the WLAN AP i and the load i2 of the WLAN AP i. The cellular communication device may optionally select one of the load i1 and the load i2 as a load threshold to be issued to the user equipment for traffic transfer. As another example, the performance requirement of the user equipment during the traffic shifting is that the average transmission rate of the associated user equipment is greater than the average transmission rate i1, the cellular communication device determines that there is no load corresponding to such performance in table 2, and the cellular communication device may set the load threshold such that the user equipment does not shift the traffic from the cellular communication device to the WLAN AP i, for example, 0 or a negative number, and the user equipment does not shift the traffic from the cellular communication network to the non-cellular communication network covered by the WLAN AP i because there is no WLAN AP i with a load less than 0 or a negative number.

When the cellular communication device issues the load threshold to the user equipment, the cellular communication device may issue a group identifier (for example, SSID) of the WLAN AP group corresponding to the load threshold to the user equipment, so that the user equipment performs service transfer in the WLAN AP group identified by the group identifier. When the cellular communication device issues the load threshold to the user equipment, the cellular communication device may also issue an identifier (e.g., BSSID) of the WLAN AP i corresponding to the load threshold to the user equipment, so that the user equipment performs service transfer on the WLAN AP i identified by the identifier. When the cellular communication device issues the load threshold to the user equipment, the cellular communication device may also issue the channel identifier of the WLAN AP i corresponding to the load threshold to the user equipment, so that the user equipment performs service transfer on the channel identified by the channel identifier. It should be noted that, in general, one WLAN AP i uses one channel, and in this case, one WLAN AP i and the channel are in one-to-one correspondence. However, it is shown in the literature that one WLAN AP i may also use multiple channels, and in this case, in order to further improve the system performance after the service of the user equipment is transferred, the cellular communication device may send the identifier of the WLAN AP i to the user equipment, and may also send the channel identifier used by the WLAN AP i to the user equipment.

Generally, in order to improve the utilization efficiency of the communication system, during the traffic transfer process of the user equipment, the user equipment may transfer the traffic to one or more WLAN APs with the lowest load. However, the load of a WLAN AP does not adequately reflect the transmission collision problem of the WLAN. For example, the increase of the associated ue may cause an increase of uplink traffic to the WLAN AP, which may cause a transmission collision of the WLAN AP to be aggravated, so that the performance of the WLAN system may be degraded sharply, which may affect the experience of all ues accessing the WLAN AP, and may cause that all ues cannot obtain the required average transmission rate or average transmission delay. In order to divert user equipment traffic to WLAN APs that are loaded as little as possible without degrading the system performance of these WLAN APs, a WLAN AP may be selected that is associated with the user equipment that is dominated by downlink traffic. Therefore, when determining the load threshold, the cellular communication device considers the load of the WLAN AP and also considers the uplink and downlink traffic ratio of the WLAN AP, see table 3.

In one aspect, it may be noted from table 3 that the average transmission rate i1 to the average transmission rate iM may not all be different. Therefore, the same average transmission rate may correspond to a plurality of different loads, and at this time, a load corresponding to a smaller uplink/downlink traffic ratio (uplink traffic divided by the following traffic) may be selected as the traffic transfer threshold. For example, for WLAN AP i, the ue determines the load threshold according to the performance requirement (corresponding to the average transmission rate/average transmission delay) for performing traffic forwarding, and the uplink/downlink traffic ratio of WLAN AP i. Assuming that the average transmission rate/average transmission delay i1 to the average transmission rate/average transmission delay iM all satisfy the performance requirement of the user equipment during service transfer, and the uplink-downlink service ratio iM is the minimum of all the uplink-downlink service ratios in table 3, the load iM is used as the load threshold.

On the other hand, in table 3, the performance requirement that is met when the user equipment performs service transfer may correspond to multiple WLAN APs (assuming that at least WLAN AP i and WLAN AP i +1 correspond to each other), and at this time, a load corresponding to a WLAN AP with a smaller uplink/downlink service may be selected from the multiple WLAN APs to be issued to the user equipment as a load threshold, so that the user equipment may transfer the service to the WLAN AP with a smaller uplink/downlink service.

TABLE 3

It should be noted that the load thresholds determined according to the uplink/downlink traffic ratios may still be multiple, and the cellular communication device may further determine the load thresholds from multiple loads by considering the packet error rate of the WLAN AP, the bandwidth of the WLAN AP, and the signal quality (including the uplink signal quality or the downlink signal quality) of the associated user equipment. Of course, the cellular communication device may further perform screening on the selected signal quality according to the average access delay, so as to set an optimal service transfer threshold, which may be similarly referred to as table 1-B. Referring to tables 4-6, similar to the determination of the load threshold assisted by the uplink/downlink traffic ratio of the WLAN AP, further description is omitted.

TABLE 4

TABLE 5

TABLE 6

Of course, the cellular communication device may also generate the following table 7 according to all the performance information and statistical information received from the non-cellular communication device, and determine the load threshold for the user equipment to perform traffic shifting.

TABLE 7

Similarly, when the traffic transfer threshold for the user equipment performing traffic transfer is the signal quality threshold, the cellular communication device may also determine the signal quality threshold with reference to table 7. For the sake of illustration, it is assumed that the values of the average transmission rate in table 7 are sequentially decreased from top to bottom. As an example, if the performance requirement of the user equipment is that the average transmission rate of the associated user equipment is not less than the average transmission rate i1 when the user equipment performs the traffic transfer, then the WLAN AP satisfying the performance requirement cannot be found from table 7, and then the cellular communication device sets the signal quality threshold to the signal quality of the user equipment which must not exceed the threshold value, so that the user equipment cannot transfer the traffic from the cellular communication network to the non-cellular communication network. As another example, if the performance requirement of the ue during the service transfer is that the average transmission rate of the associated ue is not less than the average transmission rate iM, then from table 7, the average transmission rates i1 to iM satisfy the performance requirement that the ue can perform the service transfer. The cellular communication device may issue any one of the signal quality i1 to the signal quality iM as a signal quality threshold of the user equipment to the user equipment so that the user equipment may complete the traffic transfer from the cellular to the WLAN. The cellular communication device may further consider WLAN AP i load, bandwidth, packet error rate, available backhaul capacity as assistance information to determine an appropriate signal quality threshold from signal quality i1 to signal quality iM. For example, the performance of the user equipment for performing the traffic forwarding, and the current load, bandwidth, packet error rate, and available backhaul capacity of the WLAN AP i correspond to the last row in table 7, then the signal quality iM corresponding to the last row is used as the signal quality threshold for the traffic forwarding. Of course, the cellular communication device may further perform screening on the selected signal quality according to the average access delay, so as to set an optimal service transfer threshold, which may be similarly referred to as table 1-B.

Similarly, the cellular communications device may also determine a bandwidth threshold for the WLAN AP, a WLAN AP packet error rate threshold, an available backhaul threshold for the WLAN AP, and so on. And are not described in detail herein.

Fig. 4 is a schematic structural diagram of a cellular communication device 400 according to an aspect of an embodiment of the present invention, where the cellular communication device 400 has the same functions as the cellular communication device 100. The cellular communication device 400 may perform method acts of the cellular communication device 100 to determine a traffic transfer threshold at which the user equipment performs traffic transfer. The cellular communication device 400 comprises at least a receiver 401 and a processor 402.

A receiver 401, configured to receive the performance information sent by the non-cellular communication device and statistical information of the non-cellular communication device corresponding to the performance information.

A processor 402, configured to determine, according to the performance information and the statistical information, a service transfer threshold that meets a service transfer requirement of the user equipment.

As in the description of the method embodiment, in this embodiment, the performance information is an average transmission rate or an average access delay of the associated ue in the non-cellular communication device; the statistical information is at least one of a load of the non-cellular communication device, an uplink signal quality of the associated user equipment, a downlink signal quality of the associated user equipment, an available backhaul capacity of the non-cellular communication device, an uplink and downlink traffic proportion of the non-cellular communication device, an operating bandwidth of the non-cellular communication device, and a packet error rate of the non-cellular communication device.

Optionally, the cellular communication device 400 further comprises a transmitter 403 for transmitting the traffic transfer threshold determined by the processor 402 to the user equipment. After the user equipment receives the traffic transfer threshold, traffic may be transferred from the cellular communication device 400 to the non-cellular communication device according to the traffic transfer threshold.

In order for the user equipment to be able to identify to which non-cellular communication device or devices the traffic transfer threshold is issued, the transmitter 403 may be further configured to send an identification of the non-cellular communication device to the user equipment. Since the user equipment may not be within the signal coverage of the non-cellular communication device, the user equipment may not be able to perform a traffic transfer to the non-cellular communication device even though the transmitter 403 transmits the identity of the non-cellular communication device to the user equipment. Thus, before the transmitter 403 transmits the non-cellular communication device to the user equipment, the receiver 401 may receive a list of non-cellular communication devices searched by the user equipment transmitted by the user equipment and determine by the processor 402 whether the list contains the non-cellular communication device. If the processor 402 determines that the non-cellular communication device is included in the list, the transmitter 403 transmits the identity of the non-cellular communication device to the user equipment.

Optionally, before the processor 402 determines the traffic transition threshold, the receiver 401 is further configured to receive a performance requirement of the ue during traffic transition, which is sent by the ue. Of course, for some traffic, e.g., "best effort traffic", the user equipment may not send its performance requirements for traffic shifting. For such services, the processor 402 may determine, according to a preset rule, a service transfer threshold that satisfies performance requirements of the user equipment during service transfer. The performance requirements of the user equipment during service transfer can be detailed in the description of the method embodiment.

For the above description, the processor 402 may determine a service transfer threshold when the user equipment performs service transfer according to the performance information and the statistical information, including the following two possible implementation manners.

(1) The processor 402 generates a corresponding relationship between the performance information and the statistical information according to the performance information and the statistical information. The correspondence may be generated for each cellular communication device or for a group of non-cellular communication devices consisting of a plurality of non-cellular communication devices. Reference may be made to the descriptions in tables 1-7. The processor 402 selects statistical information meeting the performance requirement of the user equipment during service transfer from the corresponding relation as the service transfer threshold. Optionally, before the processor 402 determines the traffic transfer threshold, the receiver 401 may receive a performance requirement, sent by a user equipment, when the user equipment performs traffic transfer.

(2) The processor 402 generates a corresponding relationship between the performance information and the statistical information according to the performance information and the statistical information. The correspondence may be generated for each cellular communication device or for a group of non-cellular communication devices consisting of a plurality of non-cellular communication devices. Reference may be made to the descriptions in tables 1-7. The processor 402 determines whether the performance information corresponding to the current statistical information of the non-cellular communication device meets the performance requirement of the user equipment for service transfer according to the corresponding relationship; if not, the processor 402 sets the traffic transfer threshold such that the user equipment does not meet the threshold for transferring traffic from the cellular communication device 400 to the non-cellular communication device; alternatively, if so, the processor 402 sets the traffic transfer threshold such that the user equipment satisfies the threshold for transferring traffic from the cellular communication device 400 to the non-cellular communication device.
