The new application fields put higher demands on future wireless mobile communication systems.

QCI (QoS Class Identifier; QoS, Quality of Service) characteristic standards defined by 3GPP (3rd Generation Partnership Project, third Generation standardization organization) are shown in the following table. As can be seen from the table, the transmission reliability requirement of the wireless communication system is generally 10 under the strict requirement of the time delay^-2～10^-3. For services with strict reliability requirements, the general delay requirements are not very strict. And for the most stringent latency requirements only 100ms for conversational class and 50ms for real-time gaming class.

Detailed Description

As shown in fig. 1, in a schematic diagram of a multi-channel transmission network architecture according to an embodiment of the present invention,

the user terminal can simultaneously transmit data with base stations of different systems, home base stations, wlan AP (Wireless Local Area Network, AP, Access Point), RAN (radio Access Network ) centralized control entities and core Network nodes through multi-channel transmission control.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 2, a method for configuring a transmission path according to a second embodiment of the present invention includes:

step 201, a configuration entity determines the time delay requirement and the reliability requirement of service data;

step 202, the configuration entity selects a transmission path meeting the delay requirement from transmission paths allowed to be used simultaneously by the user terminal;

step 203, the configuration entity selects at least two transmission paths which can meet the reliability requirement after combination from the transmission paths meeting the delay requirement as service data transmission paths;

and step 204, the configuration entity configures the network entity and/or the user terminal involved in the transmission according to the determined service data transmission path.

The transmission paths allowed to be used by the user terminal at the same time may be all transmission paths currently being used by the user terminal; or may be part of the transmission path. Specifically, which can be determined by the transmission path combination capable of being used simultaneously reported by the user terminal.

Such as a user terminal using path 1, path 2 and path 3 simultaneously. If the ue reports that path 1, path 2, and path 3 can be used simultaneously, the transmission paths that the ue allows to be used simultaneously may be all transmission paths currently used by the ue.

If the user terminal reports that the path 1 and the path 2, and the path 1 and the path 3 can be used simultaneously, the core network node may select the path 1 and the path 2 as transmission paths allowed to be used simultaneously by the user terminal to perform subsequent processes, and if the service data transmission path can be determined, may not select the path 1 and the path 3 as transmission paths allowed to be used simultaneously by the user terminal to perform subsequent processes.

Of course, path 1 and path 3 may be continuously selected as transmission paths permitted to be used simultaneously by the user terminal for subsequent processes, and if the traffic data transmission path can also be determined, which one is to be used as the actually used traffic data transmission path may be selected according to the set conditions.

The conditions to be set are many, and may be set from factors such as channel quality and cost.

In implementation, it may also select which group is first used as a transmission path allowed to be simultaneously used by the user terminal according to priority from the path 1 and the path 2, and the path 1 and the path 2 to perform subsequent processes, and if it can be determined that the service data transmission path may not use other groups.

The priority assignment may also be set based on channel quality, cost, and the like.

The configuration entity of the embodiment of the invention can determine the time delay requirement and the reliability requirement of the service data after receiving the notice of triggering the change of the multi-channel transmission configuration from the multi-channel transmission control entity.

In addition to the above triggering manner, other manners capable of triggering the configuration entity to start the selection process are applicable to the embodiment of the present invention. Such as manual triggering, switch mode triggering, configuration intensive multi-channel transmission mode triggering, etc.

The specific process of the multi-channel transmission control entity sending the notification of the configuration change to the configuration entity can be seen in fig. 6.

After selecting the transmission paths meeting the delay requirement from the transmission paths allowed to be used by the user terminal at the same time, the configuration entity judges whether the transmission paths meeting the delay requirement have the transmission paths meeting the reliability requirement, if so, one transmission path is selected from the transmission paths meeting the reliability requirement as a service data transmission path; otherwise, selecting at least two combined transmission paths which can meet the reliability requirement from the transmission paths meeting the time delay requirement as service data transmission paths.

In implementation, when the configuration entity selects at least two transmission paths capable of meeting the reliability requirement after combination from the transmission paths meeting the delay requirement as service data transmission paths, the transmission paths meeting the delay requirement are combined according to the current N value to obtain multiple groups of transmission paths, wherein the number of the transmission paths in each group is equal to the N value, the transmission paths in any two groups are not completely the same, and N is a positive integer greater than 1; determining a set satisfying the reliability requirement from a plurality of sets of transmission paths; and selecting one group from the groups meeting the reliability requirement as a service data transmission path.

For example, the initial value of N may be set to 2, and if the transmission paths meeting the delay requirement are path 1, path 2, and path 3, the combination is path 1 and path 2, path 1 and path 3, path 2 and path 3, and three combinations are used.

Preferably, if there is no group satisfying the reliability requirement in the plurality of groups of transmission paths, the configuration entity increases the current N value by a step value after determining that the current N value is smaller than the number of transmission paths satisfying the delay requirement;

the configuration entity judges whether the N value after the step value is increased is not larger than the number of the transmission paths meeting the time delay requirement, if so, the step of combining the transmission paths meeting the time delay requirement is returned according to the current N value; otherwise, adjusting the current N value to be not more than the number of the transmission paths meeting the time delay requirement and the previous unused N value, and returning to the step of combining the transmission paths meeting the time delay requirement according to the current N value

The configuration entity combines the transmission paths meeting the delay requirement according to the current N value to obtain a plurality of groups of transmission paths, and further comprises:

For example, the initial value of N may be set to 2, and the step value is 1, if the transmission paths satisfying the delay requirement are path 1, path 2, and path 3, the combination is path 1 and path 2, path 1 and path 3, and path 2 and path 3.

And the configuration entity checks whether a group meeting the reliability requirement exists in the three combinations, and if so, selects one group from the groups meeting the reliability requirement as a service data transmission path.

If not, the value of N is increased by 1, the value of N is 3, and the combination mode is path 1, path 2 and path 3. Checking whether the reliability requirement is met after the path 1, the path 2 and the path 3 are combined, and if so, taking the path 1, the path 2 and the path 3 as a service data transmission path; otherwise, it is determined that the reliability requirement cannot be met.

If there are multiple groups that meet the reliability requirement, which one is selected as the actually used service data transmission path can be selected according to the set conditions. The conditions to be set are many, and may be set from factors such as channel quality and cost.

The configuration entity of the embodiment of the present invention may be one of a core network node, a radio access network node, and a user terminal.

The core Network node refers to a centralized control node above a radio Access Network, and as a logical node for centrally controlling a plurality of radio Access networks, the core Network node may be an independent Network Entity, or an Access Network Discovery and Selection Function (ANDSF) function Entity, or may be disposed in an existing core Network node, such as an MME (Mobility Management Entity), a PGW (PDN GW, packet data gateway), and the like.

A radio access network node: it may be a higher-level control node, such as a RAN (Radio access network) centralized control entity in fig. 1, configured to control a network side entity (e.g., an LTE (long term Evolution) base station) of multiple Radio access networks, and control different Radio transmission paths through a Radio access side command.

A user terminal: the user terminal selects the transmission path according to the needs, and establishes the context of connection and corresponding service transmission only on the needed transmission path, such as bearer establishment.

The following is described separately for different execution bodies.

Firstly, the configuration entity is a core network node.

When the configuration entity configures the radio access network node:

and notifying the wireless access network nodes participating in service data transmission, such as a base station of an LTE system, a 3G system RNC, a base station, a WiFi AP and the like, through network side signaling, such as non-access stratum signaling NAS signaling.

The specific notification mode is as follows:

informing the wireless access network node to participate in multi-path transmission according to the determined service data transmission path, and optionally informing the wireless access network node of the transmission path and parameter information; or

And establishing the bearing of the corresponding service on the selected service data transmission path with the wireless access network node.

The specific process of establishing the bearer of the service by different wireless communication systems is different, for example, the LTE system may establish the bearer of the corresponding service according to the existing LTE system.

As shown in fig. 6, the method for configuring a transmission path by six triggers in the embodiment of the present invention includes:

601, the multi-channel control entity determines that at least one transmission channel pre-configured by a specific user terminal is abnormal;

step 602, the multi-channel control entity sends a notification for triggering multi-channel transmission configuration change to a configuration entity, so that the configuration entity selects a transmission path meeting the delay requirement from transmission paths simultaneously used by a user terminal, selects at least two transmission paths capable of meeting the reliability requirement after combination from the transmission paths meeting the delay requirement as service data transmission paths, and configures the devices involved in transmission according to the determined service data transmission paths.

The multi-channel control entity in the embodiment of the present invention may be a configuration entity in the embodiment of the present invention, or may be a higher-level entity such as an operation and Maintenance (OAM).

The specific process of triggering the method for configuring the transmission path can be seen in example four below.

The solution of the invention is described below by referring to different entities as configuration entities to name a few examples.

Example one: the configuration entity is a core network node.

Step 0: the core network node acquires the time delay requirement and the reliability requirement of the service data required by the user terminal, judges whether the time delay requirement and the reliability requirement of the service required by the user terminal need to be subjected to multi-path transmission, and if so, executes the step 1; otherwise, selecting any one of the available transmission paths currently used by the user terminal, and executing the step 4.

In the implementation, when judging whether the time delay requirement and the reliability requirement of the service required by the user terminal need to be subjected to multi-path transmission, if the time delay and the reliability requirement of the service data are lower, the user terminal can determine that the multi-path transmission is not required, otherwise, the user terminal can determine that the multi-path transmission is required.

The reliability of the embodiment of the invention refers to the reliability under a certain time delay. Reliability is a quantitative indicator, and refers to parameters such as a packet loss rate within a certain time period that can reflect reliability requirements.

In implementation, the core network node determines QoS requirements of different transmission channels according to the configuration decomposition; and establishing the same service bearer in different transmission channels according to the QoS requirements decomposed to the transmission channels. For example if the service reliability requirement is 10^-9Under the activation of multi-path transmission, the reliability requirement of the 5G link is 10^-6LTE link up to 10^-2Wifi Link up to 10^-1And the delay per link is less than a certain delay (e.g., 5 ms).

Step 1: the core network node judges whether the user terminal can use a plurality of transmission paths at the same time, if so, determines the transmission paths (namely a transmission path set 0) which are allowed to be used at the same time by the user terminal, and executes the step 2; otherwise, selecting any one of the available transmission paths currently used by the user terminal, and executing the step 4.

Whether the user terminal can use a plurality of transmission paths at the same time can be judged according to the information whether the user terminal has the multi-path transmission capability or not reported by the user terminal.

The transmission paths allowed to be simultaneously used by the user terminal may be all transmission paths currently being used by the user terminal; or may be part of the transmission path. Specifically, which can be determined by the transmission path combination capable of being used simultaneously reported by the user terminal.

Step 2: the core network node performs time delay judgment on different transmission paths in the transmission path set 0, and determines the transmission path set 1 capable of meeting the time delay requirement and each transmission path in the transmission path set 1 as a parameter corresponding to meeting the time delay requirement.

Wherein the parameters include, but are not limited to, some or all of the following:

a retransmission mode (including whether ARQ (Automatic Repeat reQuest) retransmission is supported or not, and whether HARQ (Hybrid Automatic Repeat reQuest) retransmission is supported or not);

the maximum retransmission time limit meeting the delay requirement is met.

And step 3: the core network node judges the reliability of the transmission path set 1 selected in the step 1:

judging whether one or more transmission paths (transmission path set 2) meet the reliability requirement, if so, selecting one transmission path as a service data transmission path of the user terminal (arbitrarily selecting or selecting the transmission path with the minimum time delay or selecting the transmission path based on other factors such as expense, load and the like), and determining not to start multi-channel transmission;

otherwise, determining to start multi-channel transmission.

If the multichannel transmission is determined to be started, calculating the reliability of the user terminal after the received data are combined when the two transmission paths in the transmission path set 1 are transmitted simultaneously, if the combination meeting the reliability exists, obtaining a transmission path combination set 3 (pairwise combination), and selecting one combination as a service data transmission path of the user terminal; the two-to-two combination in the transmission path combination set 3 is a set of any two paths that the user terminal can simultaneously connect and perform data transmission, and one path may be combined with multiple paths two-to-two (e.g., a combination of a 5G cell and an LTE macro cell under the same coverage, a combination of a 5G cell and an LTE micro cell under the same coverage, etc.).

If the combination which meets the reliability does not exist, the reliability of the user terminal after the received data is merged by the user terminal when the three transmission paths in the transmission path set 1 are transmitted simultaneously is calculated, if the combination which meets the reliability exists, a transmission path combination set 4 (three combinations) can be obtained, and one combination is selected as a service data transmission path of the user terminal;

if the combination of the reliability is not met, increasing the number of the combined paths, and judging until the combination of the paths meeting the reliability is obtained or all available paths can not meet the reliability requirement when being transmitted simultaneously, and if all available paths can not meet the reliability requirement when being transmitted simultaneously, determining that the reliability requirement can not be met.

If the reliability requirement can not be met as a result of the judgment, the user terminal is informed, and/or the network/service overall management unit can not meet the reliability requirement.

If the traffic data transmission path can be determined, step 4 is performed.

And 4, step 4: the core network node informs the radio access network node and the user terminal of the path selection result and the transmission parameters.

Informing the radio access network node specifically:

a Radio access Network side node participating in service data transmission is notified through a Network side signaling (such as a non-access stratum signaling NAS signaling), such as a base station of an LTE system, a 3G system RNC or a base station, a WiFi (Radio Network Controller ) AP, and the like, and two notification methods are available:

the method comprises the steps of firstly, explicitly informing a wireless access network node to participate in multi-path transmission, and optionally informing the wireless access network node of a transmission path and parameters of the transmission path;

and secondly, establishing the load bearing of the corresponding service on the selected transmission path according to the wireless communication system of the transmission path.

The specific process of establishing the bearer corresponding to the service by different wireless communication systems is different, for example, the LTE system may establish the bearer corresponding to the service according to the existing LTE system. Each wireless communication system mode can be established according to the existing mode, and the specific process is not described in detail.

Correspondingly, the radio access network node establishes the load bearing of the corresponding service according to the received notification.

There are several ways to notify the user terminal:

the first method is as follows: the core network node or the core network node notifies the user terminal to start multi-channel transmission and parameters of a transmission path, such as a transmission channel, data merging parameters and the like, by adopting non-access stratum signaling (such as NAS signaling) through a core network node entity (such as MME);

the second method comprises the following steps: after the core network node informs a radio access network node (such as a base station) to participate in multi-channel transmission, different radio access network nodes respectively inform a user terminal to start multi-channel transmission and parameters of a transmission path, such as a transmission channel, data merging parameters and the like, through radio access signaling (such as RRC signaling);

the third method comprises the following steps: the core network node establishes the same service load for the UE in different wireless access systems respectively, and the UE starts the multi-channel transmission operation according to the same service load.

Correspondingly, after receiving the configuration performed by the configuration entity according to the service data transmission path, the user terminal establishes wireless connection on the plurality of transmission paths according to the configuration, and performs data transmission.

During transmission, the user terminal receives data from a plurality of transmission paths and combines the data from different transmission paths; or

Example two, the configuration entity is a radio access network node.

Step 0: the wireless access network node acquires the time delay requirement and the reliability requirement of the service data required by the user terminal, judges whether the time delay requirement and the reliability requirement of the service required by the user terminal need to be subjected to multi-path transmission, and if so, executes the step 1; otherwise, selecting any one of the available transmission paths currently used by the user terminal, and executing the step 4.

Step 1: the radio access network node judges whether the user terminal can use a plurality of transmission paths at the same time, if so, determines the transmission paths (namely a transmission path set 0) which are allowed to be used at the same time by the user terminal, and executes the step 2; otherwise, selecting any one of the available transmission paths currently used by the user terminal, and executing the step 4.

If the user terminal reports that the path 1 and the path 2, and the path 1 and the path 3 can be used simultaneously, the radio access network node may select the path 1 and the path 2 as transmission paths allowed to be used simultaneously by the user terminal to perform subsequent processes, and if the service data transmission path can be determined, may not select the path 1 and the path 3 as transmission paths allowed to be used simultaneously by the user terminal to perform subsequent processes.

Step 2: the wireless access network node performs time delay judgment on different transmission paths in the transmission path set 0, and determines the transmission path set 1 which can meet the time delay requirement and each transmission path in the transmission path set 1 as a parameter corresponding to the time delay requirement.

retransmission modes (including whether ARQ retransmission is supported or not and whether HARQ retransmission is supported or not);

the maximum retransmission time limit meeting the delay requirement is met.

And step 3: the wireless access network node judges the reliability of the transmission path set 1 selected in the step 1:

otherwise, determining to start multi-channel transmission.

If the traffic data transmission path can be determined, step 4 is performed.

And 4, step 4: and the wireless access network node informs the wireless access network node and the user terminal of a path selection result and a transmission parameter.

Informing the core network nodes specifically:

informing a core network node (one or more radio access systems controlled by the core network node, that is, one core network node may control one or more radio access network nodes) to start multi-channel transmission, wherein the informing content includes but is not limited to a user terminal or a user terminal group identifier, a service type identifier and multi-channel transmission parameters;

correspondingly, the core network node receives the configuration performed by the configuration entity according to the service data transmission path, decomposes and determines the QoS requirements of different transmission channels according to the configuration, and establishes the same service bearer in different transmission channels according to the QoS requirements decomposed to the transmission channels.

In implementation, the core network node depends on the service QoS requirements (e.g., delay of 10ms, reliability 10)^-4) Resolving QoS requirements for different transmission channels(e.g., 10ms delay of transmission channel 1, 10 reliability)^-2The time delay of the transmission channel 2 is 10ms, and the reliability is 10^-2)。

Informing the base station of the details:

informing different base stations to establish the load bearing of the corresponding service for the user terminal, and parameters of a transmission path, such as a retransmission mode and maximum retransmission time limit of the corresponding service requirement;

Informing the user terminal of the details:

the RAN side signaling is used for notifying the user terminal to start multi-channel transmission, the signaling can be forwarded by the base station, the notification mode can be realized by establishing wireless bearing of the same service for the user terminal on different transmission channels and setting the retransmission mode and the maximum retransmission times of the wireless bearing.

Example three, the configuration entity is a user terminal.

Step 0: the user terminal obtains the time delay requirement and the reliability requirement of the service data required by the user terminal, judges whether the time delay requirement and the reliability requirement of the service required by the user terminal need to be transmitted in a multipath way or not, and if so, executes the step 1; otherwise, selecting any one of the available transmission paths currently used by the user terminal, and executing the step 4.

Step 1: the user terminal judges whether the user terminal can use a plurality of transmission paths at the same time, if yes, the transmission paths (namely, the transmission path set 0) which are allowed to be used at the same time by the user terminal are determined, and the step 2 is executed; otherwise, selecting any one of the available transmission paths currently used by the user terminal, and executing the step 4.

If the user terminal reports that the path 1 and the path 2, and the path 1 and the path 3 can be used simultaneously, the user terminal may select the path 1 and the path 2 as transmission paths allowed to be used simultaneously by the user terminal to perform a subsequent process, and if the service data transmission path can be determined, the path 1 and the path 3 may not be selected as transmission paths allowed to be used simultaneously by the user terminal to perform the subsequent process.

Step 2: the user terminal performs time delay judgment on different transmission paths in the transmission path set 0, and determines the transmission path set 1 which can meet the time delay requirement and each transmission path in the transmission path set 1 as a parameter corresponding to the time delay requirement.

the maximum retransmission time limit meeting the delay requirement is met.

And step 3: the user terminal judges the reliability of the transmission path set 1 selected in the step 1:

otherwise, determining to start multi-channel transmission.

If the traffic data transmission path can be determined, step 4 is performed.

And 4, step 4: the user terminal informs the core network node and the wireless network side node of the path selection result and the transmission parameter.

Informing the core network nodes specifically:

notifying a core network node (one or more wireless access systems controlled by the core network node) to start multi-channel transmission through non-access stratum signaling, wherein the notification content comprises but is not limited to a user terminal or a user terminal group identifier, a service type identifier and multi-channel transmission parameters;

In implementation, the core network node depends on the service QoS requirements (e.g., delay of 10ms, reliability 10)^-4) And resolving and determining QoS requirements of different transmission channels (such as 10ms of transmission channel 1 delay and 10 reliability)^-2The time delay of the transmission channel 2 is 10ms, and the reliability is 10^-2)。

Informing the radio access network node specifically:

the wireless access network node is informed to inform the user terminal to start multi-channel transmission and parameters of a transmission path, such as a transmission channel, data merging parameters and the like, or the wireless access network node is not informed but is informed to establish the same service bearer for the UE in different wireless access systems.

Example four: a multi-channel transmission path is preconfigured.

For a specific type of user terminal (such as a specific machine type terminal) and a specific service, multi-channel transmission is fixedly used, and according to the type and the capability of the user terminal, a fixed accessible specific wireless access network uses a specific transmission channel for multi-channel transmission.

Pre-configuring the corresponding relation of a user terminal, a service and a transmission channel and multi-channel transmission parameter information in a multi-channel transmission control entity and/or the user terminal;

step 1: a multichannel transmission control entity or a user terminal informs a core network and/or a wireless access network side entity (such as a base station) of multichannel transmission information and parameters; or, pre-configuring information corresponding to the terminal, the service and the multi-channel transmission configuration parameter at a core network and/or a radio access network side entity (such as a base station);

step 2: when a specific user terminal starts specific service transmission, multi-channel parameter configuration corresponding to a multi-channel transmission control entity, a core network and a wireless access network entity is activated;

and step 3: according to the pre-configuration information, a specific user terminal establishes connection on a pre-configuration transmission channel, performs service data transmission according to pre-configuration parameters, and performs multi-transmission channel data processing;

step five: if one or more pre-configured transmission channels are abnormal (cannot work according to the time delay and reliability set in the pre-configuration process), the multi-channel transmission control entity triggers a multi-channel transmission configuration change process to inform a specific user terminal and other network entities participating in multi-channel transmission;

step six: and triggering to enter one of the first to third embodiments according to different decision points, and performing path selection and parameter configuration of multi-channel transmission.
