Description

Method for receiving and transmitting equipment identification code and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for receiving and transmitting an equipment identification code and a related device.

Background

The technology of communicating by utilizing the characteristic of two or more user equipments being in physical proximity to each other has been an important component of building future local networks.

For example, after obtaining a device identification code, the user equipment a reports the device identification code found by the user equipment a through establishing a Radio Resource Control (RRC) link, and after obtaining a user identifier corresponding to the device identification code through authentication, the server of the core network issues the user identification code to the device of the user equipment a through the RRC link established before. If the user equipment a is in a busy area, the user equipment a frequently discovers the device identification code of the unspecified target user, and if each device identification code is discovered, the device identification code is sent to the server in a synchronous manner, which causes the user equipment a to frequently establish an RRC link, thereby causing waste of channel resources and consuming a large amount of power of the user equipment a.

Further, after the server of the core network issues the user identification code to the user equipment a through the previously established RRC link, the RRC link between the user equipment a and the server is maintained, and when the user equipment a obtains another equipment identification code, the equipment identification code is continuously sent to the server through the RRC link. Compared with the method described above, the method has less signaling for establishing a link, but the method is always maintained in an RRC link state, and both the core network and the base station need to maintain the context related to the ue, and in order to maintain the link state, the ue a needs to periodically send information such as sRS (Service reference signal), BSR (Buffer Status Report), etc., and the base station and the core network also need to periodically maintain the state of the ue a, and at the same time, the ue a consumes more power.

Therefore, the ue reports the device id of the first neighboring ue every time the ue finds that the device id is found, and this synchronous transmission of the device id wastes channel resources and power of the ue.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a system structure diagram of an embodiment of a method for sending a device identifier according to the present invention, where the method for sending and receiving a device identifier according to the present invention is implemented based on the system architecture shown in fig. 1, as shown in fig. 1, a user equipment 10 is connected to a target device 20, and the user equipment 10 sends information related to the device identifier to the target device 20.

Referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of a method for sending an equipment id according to the present invention. As shown in fig. 2, the method for sending the device identification code of the present invention specifically includes the following steps:

step 101: the user equipment 10 detects a first neighboring user equipment and acquires a device identification code of the first neighboring user equipment when the first neighboring user equipment is detected.

Step 102: the user equipment 10 receives control information from the target device 20 and transmits the device identification code of the first neighbouring user equipment to the target device 20 in a non-synchronous manner in dependence on the control information.

It should be noted that the "asynchronous mode" described in this embodiment specifically includes the following implementation manners: the user equipment 10 stops sending the equipment identification code of the first neighboring user equipment to the target equipment 20 within a preset valid time according to the control information, and sends the equipment identification code of the first neighboring user equipment to the target equipment 20 after the preset valid time; and uniformly transmitting the device identification codes of the plurality of first neighboring user equipments acquired within the predetermined period of time to the target device 20 according to the control information.

In this embodiment, the ue 10 transmits the device id of the first neighboring ue to the target device 20 in an asynchronous manner, and compared with a synchronous transmission manner in which the device id of the neighboring ue 10 is synchronously transmitted to the target device 20 immediately after detecting one neighboring ue 10 and acquiring the device id of the neighboring ue 10, the transmission method of the device id of this embodiment can avoid continuously establishing a synchronous connection with the target device 20, so that the frequency of transmitting the device id can be reduced, channel resources can be saved, and power consumption of the ue 10 can be reduced.

Referring to fig. 3, fig. 3 is a flowchart of another embodiment of a method for sending a device identifier according to the present invention, in which the control information is a pre-download packet and the target device 20 is a server, as shown in fig. 3, the method for sending a device identifier specifically includes the following steps:

step 201: the user equipment 10 detects a first neighboring user equipment and acquires a device identification code of the first neighboring user equipment when the first neighboring user equipment is detected.

Step 202: the ue 10 establishes an RRC link with the target device 20 through an RRC link establishment signaling, and sends the device identifier of the first neighboring ue to the server through the RRC link, so that the server finds the device identifier of the first neighboring ue in the context table, generates a pre-download packet according to the context table, and sends the pre-download packet to the ue 10 through an RAB (Radio Access Bearer) channel, where the pre-download packet includes a preset validity time, a neighboring device identifier corresponding to the device identifier of the first neighboring ue, and a user identifier corresponding to the neighboring device identifier and the device identifier of the first neighboring ue, where the neighboring device identifier is the device identifier of the ue 10 within a predetermined distance from the first neighboring ue.

Step 203: the user equipment 10 receives the pre-download information packet from the server, stores the adjacent equipment identification code and the user identification code corresponding to the adjacent equipment identification code and the equipment identification code of the first adjacent user equipment, and stops sending the equipment identification code of the first adjacent equipment or the adjacent equipment identification code to the server when acquiring the equipment identification code of the first adjacent equipment or the adjacent equipment identification code of the first adjacent equipment within preset effective time; and when the equipment identification code of the first adjacent equipment or the adjacent equipment identification code is acquired after the preset effective time, the equipment identification code of the first adjacent equipment or the adjacent equipment identification code is sent to the server.

Specifically, in step 203, if the ue 10 acquires the device identifier of the second neighboring ue when discovering the second neighboring ue, the ue 10 may determine whether the device identifier of the second neighboring ue is one of the device identifier of the first neighboring ue and the neighboring device identifier, if so, stop sending the device identifier of the second neighboring ue to the server within a preset validity time, and if not, send the device identifier of the second neighboring ue to the server.

It should be noted that the preset effective time is optional and can be set according to actual needs, and for the user equipment 10 in the vicinity as a non-specific target user, such as a merchant, the preset effective time can be set to be 3 months, because the merchant and the geographic area are bound for a period of time, and the relationship between merchants usually remains unchanged for a longer time.

Optionally, after the preset valid time is over, the user equipment 10 may clear the stored neighboring equipment identification code and the user identification code corresponding to the neighboring equipment identification code, in an embodiment of the present invention, the preset valid time may be set according to actual needs, and is generally related to the valid date of the neighboring user equipment 10, so that when the preset valid time is over, it indicates that the neighboring user equipment 10 is invalid, and if the merchant moves away after the preset valid time, the stored neighboring equipment identification code and the user identification code corresponding to the neighboring equipment identification code become invalid data, and clearing thereof may save a storage space and reduce a load.

In contrast to the synchronous transmission mode in which the device identification codes of the neighboring user devices 10 are synchronously transmitted to the target device 20 immediately after one of the neighboring user devices 10 is detected and the device identification codes of the neighboring user devices 10 are acquired, the user device 10 transmits the device identification code of the first neighboring user device to the target device 20 in a non-synchronous manner. Specifically, in this embodiment, when the user equipment 10 acquires the device identification code of the first neighboring device or the neighboring device identification code within the preset valid time, the user equipment stops sending the device identification code of the first neighboring device or the neighboring device identification code to the server; and when the device identification code of the first neighboring device or the neighboring device identification code is acquired after the preset valid time, the device identification code of the first neighboring device or the neighboring device identification code is sent to the server, and the asynchronous sending method only sends the relevant information to the target device 20 after the preset valid time, so that the continuous establishment of synchronous connection with the target device 20 can be avoided, the frequency of sending the device identification code can be reduced, the channel resource can be saved, and the power consumption of the user equipment 10 can be reduced.

Referring to fig. 4, fig. 4 is a flowchart of another embodiment of a method for sending a device identifier according to the present invention, in which the control information is a discovery target report message and the target device 20 is a base station.

Wherein the base station broadcasts in a broadcast message a segment of the shared channel resource that can be used by the user equipment 10 without establishing a dedicated RRC link. Specifically, a field may be added to the broadcasted SIB (system information Blocks) information: DS-CH (discovery shared channel): a modulation mode, an allowable upper limit, an appearance period, a pilot group and a corresponding RNTI (Radio network terminal identification), where the pilot group may have one or more pilot identifiers but all correspond to one RNTI).

As shown in fig. 4, the method for sending the device identification code of the present invention specifically includes the following steps:

step 401: the user equipment 10 detects a plurality of first neighboring user equipments within a predetermined period of time, and acquires the equipment identification codes of the first neighboring user equipments when the first neighboring user equipments are detected.

Step 402: through a shared channel broadcasted by a base station, a user equipment 10 receives a discovery target report message from the base station, and after receiving the discovery target report message, sets a plurality of equipment identification codes of first neighboring user equipment and a user identification code corresponding to the user equipment 10 in a Media access control protocol data unit (MAC PDU) packet, and sends the MAC PDU packet to the base station through the shared channel, wherein the discovery target report message includes an ACK/NACK indicator and a pilot identifier.

Optionally, in step 402, the ue 10 sends the MAC PDU packet to the base station through the shared channel when a preset condition is met, where the preset condition is: the ue 10 confirms that the ACK/NACK indicator in the discovery target report message is set to ACK. And, when the ue 10 determines that the ACK/NACK indicator in the target report message is set to NACK, it waits for the shared channel to be in an idle state, and then sends the MAC PDU packet to the base station through the shared channel.

Optionally, the header of the MAC PDU packet is provided with an indication bit, where the indication bit is used to indicate whether the MAC PDU packet is the last data packet.

Optionally, the user identification code is embodied as a device identification code of the user device 10.

It should be noted that, after receiving the MAC PDU packet, the base station parses the MAC PDU packet, generates S1AP FP (S1application frame protocol ) packet according to the device identification codes of the first neighboring ue and the ue id corresponding to the ue 10, and sends the S1AP FP packet to the server connected to the base station.

Specifically, a data structure of a discovery target report message may refer to fig. 5, where fig. 5 is a data structure diagram of a discovery target report message in another embodiment of the method for sending an identification code of a device according to the present invention, and as shown in fig. 5, the discovery target report message includes an ACK/NACK indicator, a Timing Advance command (Timing Advance command), and a pilot identifier, where the pilot identifier may be set in a Reserved bit (Reserved).

Also, the data structure of the MAC PDU packet can be seen in fig. 6, where fig. 6 is a data structure diagram of the MAC PDU packet in another embodiment of the method for sending the device identification code of the present invention, as shown in fig. 6, the MAC PDU packet includes the user identification code, the number of device identification codes, the device identification code 1, … …, the device identification code n, and the check code. Wherein the device identification code 1, … … is a device identification code of a plurality of first proximity user devices.

The data structure of the S1AP FP packet can be seen in fig. 7, where fig. 7 is a data structure diagram of the S1AP FP packet in another embodiment of the method for sending the device identifier code of the present invention. As shown in fig. 7, the S1AP FP packet includes a frame number, a frame length, a frame header check code, a base station identifier, a user identifier 1, a device identifier corresponding to the user identifier 1, a user identifier 2, a device identifier corresponding to the user identifier 2, … …, a user identifier n, a device identifier corresponding to the user identifier n, and a check digit.

In this embodiment, the ue 10 obtains the device identification codes of multiple first neighboring ues in a predetermined time period, receives a discovery target report message from the base station through a shared channel broadcast by the base station, sets the device identification codes of the multiple first neighboring ues and the user identification code corresponding to the ue 10 in an MAC PDU packet in response to the discovery target report message, sends the MAC PDU packet to the base station through the shared channel, and the base station parses the MAC PDU packet, generates an S1AP FP packet according to the device identification codes of the multiple first neighboring ues and the user identification corresponding to the ue 10, and sends the S1AP FP packet to the server. Therefore, the ue 10 does not perform synchronous transmission immediately after acquiring the device id of the first neighboring ue, but acquires the device ids of a plurality of first neighboring ues in a predetermined time period, and then transmits the MAC PDU packet to the base station through the shared channel broadcasted by the base station, and the base station parses the MAC PDU packet to generate an S1AP FP packet and transmits the S1AP FP packet to the server, so that the server acquires the uniformly transmitted device ids of the plurality of first neighboring ues in an asynchronous transmission manner. The asynchronous sending method uniformly sends the relevant information to the base station, and the base station forwards the relevant information to the server, so that the continuous establishment of synchronous connection with the base station can be avoided, the sending frequency of the equipment identification code can be reduced, the channel resource is saved, and the electric quantity loss of the user equipment 10 is reduced.

Since the asynchronous transmission method disclosed in this embodiment uniformly transmits the device identifiers of a plurality of first neighboring ue to the base station through the shared channel provided by the base station, it is avoided to continuously establish a synchronous connection with the base station, so as to reduce the frequency of device identifier transmission, save channel resources, and reduce the power consumption of the ue 10.

Referring to fig. 8, fig. 8 is a flowchart illustrating an embodiment of a method for receiving an identification code of a device according to the present invention. As shown in fig. 8, the method for sending the device identification code of the present invention specifically includes the following steps:

step 501: the target device 20 sends control information to the user device 10.

Step 502: the target device 20 receives the device identification code of the first neighboring user device, which is transmitted by the user device 10 in a non-synchronous manner according to the control information, wherein the device identification code of the first neighboring user device is acquired by the user device 10 from the first neighboring user device when the first neighboring user device is detected.

It is noted that the receiving, by the target device 20, the device identification code of the first neighboring user equipment transmitted by the user equipment 10 in a non-synchronous manner according to the control information specifically includes the following implementation manners: the target device 20 receives the device identification code of the first neighboring user device, which is sent after the preset time and is stopped by the user device 10 within the preset effective time according to the control information; and the target device 20 receives the device identification codes of the plurality of first neighboring user devices, which are acquired within the predetermined time period and are uniformly transmitted by the user device 10 according to the control information.

In the prior art, the target device 20 prepares to establish a connection with the ue 10 that has just detected the device id of the neighboring ue 10 at any time and receives the device id of the neighboring ue 10, but in this embodiment, the target device 20 receives the device id of the first neighboring ue that is sent by the ue 10 in an asynchronous manner, and does not need to establish a connection with the ue 10 at any time, so the receiving method of the device id of this embodiment can avoid establishing a synchronous connection with the ue 10 as soon as the device id of the first neighboring ue is detected, and can reduce the frequency of receiving the device id, save channel resources, and reduce the power consumption of the ue 10.

Referring to fig. 9, fig. 9 is a flowchart of another embodiment of a method for receiving a device identifier according to the present invention, where in this embodiment, the control information is a pre-download packet, and the target device 20 is a server, and as shown in fig. 9, the method for sending a device identifier specifically includes the following steps:

step 601: the server sends control information to the user equipment 10.

Step 602: the server receives the device identification code transmitted by the user equipment 10 through the RRC link established by the user equipment 10 with the server through the RRC link establishment signaling,

step 603: the server searches the equipment identification code in the proximity relation table, generates a pre-download information packet according to the proximity relation table and sends the pre-download information packet to the user equipment 10 through an RAB channel, wherein the pre-download information packet comprises preset effective time, a neighboring equipment identification code corresponding to the equipment identification code of the first neighboring user equipment and a user identification code corresponding to the neighboring equipment identification code, and the neighboring equipment identification code is the equipment identification code of the user equipment 10 within a preset distance from the first neighboring user equipment, so that the user equipment 10 receives the pre-download information packet from the server, stores the neighboring equipment identification code corresponding to the equipment identification code of the first neighboring user equipment and the user identification code corresponding to the neighboring equipment identification code, and stops sending the equipment identification code, the user identification code and the user identification code of the first neighboring equipment when the equipment identification code or the neighboring equipment identification code of the first neighboring equipment is obtained within the, Or the adjacent equipment identification code is sent to the server; and when the equipment identification code of the first adjacent equipment or the adjacent equipment identification code is acquired after the preset effective time, the equipment identification code of the first adjacent equipment or the adjacent equipment identification code is sent to the server.

The format of the proximity relation table can be shown in the following table 1.1, for example:

TABLE 1.1

As shown in table 1.1, in the proximity relationship table, the proximity device identification codes corresponding to the device identification code 1 are the device identification code 89, the device identification code 102, and the device identification code 50; the adjacent device identification codes corresponding to the device identification code 2 are the device identification code 23, the device identification code 58, the device identification code 200, and the device identification code 67.

Wherein, the distance between the user equipment 10 corresponding to the equipment identification code 1 and the user equipment 10 corresponding to the equipment identification code 89, the equipment identification code 102 and the equipment identification code 50 is within 300-500 meters; the distance between the user equipment 10 corresponding to the equipment identification code 2 and the user equipment 10 corresponding to the equipment identification codes 23, 58, 200 and 67 is within 300 and 500 meters.

It should be noted that the distance range of 300-500 m is only one preferred embodiment of the present invention, and the present invention does not limit the specific value thereof.

Specifically, the server may generate the context table in advance by:

alternatively, the server stores an electronic map, and the server generates the proximity relation table based on the electronic map, the position information registered by the plurality of different user devices 10, and the device identification code.

Alternatively, the server receives the location information and the device identification code transmitted by the plurality of different user devices 10, and the electronic map, and generates the proximity relation table based on the location information, the electronic map, and the device identification code.

Alternatively, the server receives the device identification codes transmitted by the plurality of different user devices 10 and the device identification codes of the neighboring user devices 10 with the highest frequency detected by the plurality of different user devices 10, and generates the context table according to the device identification codes and the device identification codes of the neighboring user devices 10 with the highest frequency detected by the plurality of different user devices 10.

In contrast to the synchronous transmission mode in which the device identification codes of the neighboring user devices 10 are synchronously transmitted to the target device 20 immediately after one of the neighboring user devices 10 is detected and the device identification codes of the neighboring user devices 10 are acquired, the user device 10 transmits the device identification code of the first neighboring user device to the target device 20 in a non-synchronous manner. Specifically, in this embodiment, when the user equipment 10 acquires the device identification code of the first neighboring device or the neighboring device identification code within the preset valid time, the user equipment stops sending the device identification code of the first neighboring device or the neighboring device identification code to the server; and when the device identification code of the first neighboring device or the neighboring device identification code is acquired after the preset valid time, the device identification code of the first neighboring device or the neighboring device identification code is sent to the server, and the asynchronous sending method only sends the relevant information to the server after the preset valid time, so that the server can be prevented from continuously establishing synchronous connection with the user equipment 10, the frequency of receiving the device identification code can be reduced, the channel resource is saved, and the electric quantity loss of the user equipment 10 is reduced.

Referring to fig. 10, fig. 10 is a flowchart of another embodiment of the method for receiving the device identification code according to the present invention, where in the embodiment, the control information is a discovery target report message and the target device 20 is a base station, and as shown in fig. 10, the method for receiving the device identification code specifically includes the following steps:

step 701: the base station sends a discovery target report message to the user equipment 10 through a shared channel broadcasted by the base station, wherein the discovery target report message comprises an ACK/NACK indicator bit and a pilot frequency identifier.

Step 702: the base station receives a MAC PDU packet sent by the ue 10 through the shared channel, where the MAC PDU packet is generated by setting, in the MAC PDU packet, the device identification codes of multiple first neighboring ues and the user identification codes corresponding to the ue 10 after the ue 10 receives the discovery target report message, and the device identification code of the first neighboring ue is obtained from the multiple first neighboring ues when the ue 10 detects the multiple first neighboring ues within a predetermined time period.

Step 703: the base station analyzes the MAC PDU packet, generates an S1AP FP packet according to the equipment identification code of the first adjacent user equipment and the user identification code corresponding to the user equipment 10, and sends the S1AP FP packet to the server.

After step 702, the method for receiving the identification code of the device of the present invention may further comprise the steps of: after receiving the mac pdu packet sent by the ue 10 through the shared channel broadcasted by the base station, the base station sends ACK response information to the ue 10, where the ACK response information is provided with the device identifier code of the ue 10.

Optionally, in step 701, the base station sends the discovery target reporting message to the ue 10 through the shared channel broadcasted by the base station under the condition that a preset condition is met, where the preset condition is: the base station receives a pilot signal sent by the user equipment 10 through the shared channel, where the pilot signal carries a pilot identifier.

In step 701, the base station may detect whether the broadcast shared channel is in an idle state, and if so, send a discovery target reporting message with an ACK/NACK (Acknowledgement/Negative Acknowledgement) indication bit being ACK to the user equipment 10, otherwise, send a discovery target reporting message with an ACK/NACK indication bit being NACK to the user equipment 10. After receiving the discovery target report message with the ACK/NACK indicator being ACK, the user equipment 10 sends the MAC PDU packet to the base station, and after receiving the discovery target report message with the ACK/NACK indicator being ACK, the user equipment 10 waits for the shared channel to be in an idle state, and then sends the MAC PDU packet to the base station through the shared channel.

Optionally, in step 702, after receiving the MAC PDU packet sent by the user equipment 10 through the shared channel, the base station may further send ACK response information to the user equipment 10, where the ACK response information is provided with the equipment identification code of the user equipment 10. After receiving the ACK response message, the user equipment 10 confirms that the base station receives the MAC PDU packet. If the user equipment 10 does not receive the ACK response message, it indicates that the base station does not receive the MAC PDU packet, at this time, the user equipment 10 needs to repeatedly send the MAC PDU packet, the repeated sending can be performed in the next DSCH resource period of the shared channel, and the number of times of the repeated sending can be set by the base station.

When the base station receives the pilot signal sent by other user equipment 10 at the same time when the user equipment 10 retransmits the MAC PDU packet, indicating that it is expected to use the DS-CH corresponding to the pilot identifier of the pilot signal later, the base station should send a NACK response message so as not to let other user equipment 10 continue to send the pilot signal with the same pilot identifier.

If the ACK/NACK indicator of RAR (Radio access response) information received after the ue 10 transmits the pilot signal is set to NACK, the ue 10 may reselect a pilot signal with a different pilot identifier for transmission before the next transmission opportunity arrives. If no RAR information is received, the ue 10 may increase the power to retransmit the pilot signal, and the number of retransmissions and the power per increment may be set in the broadcast message of the base station.

In this embodiment, the ue 10 obtains the device identification codes of multiple first neighboring ues in a predetermined time period, receives a discovery target report message from the base station through a shared channel broadcast by the base station, sets the device identification codes of the multiple first neighboring ues and the user identification code corresponding to the ue 10 in an MAC PDU packet in response to the discovery target report message, sends the MAC PDU packet to the base station through the shared channel, and the base station parses the MAC PDU packet, generates an S1AP FP packet according to the device identification codes of the multiple first neighboring ues and the user identification corresponding to the ue 10, and sends the S1AP FP packet to the server. Therefore, the ue 10 does not perform synchronous transmission immediately after acquiring the device id of the first neighboring ue, but acquires the device ids of a plurality of first neighboring ues in a predetermined time period, and then transmits the MAC PDU packet to the base station through the shared channel broadcasted by the base station, and the base station parses the MAC PDU packet to generate an S1AP FP packet and transmits the S1AP FP packet to the server, so that the server acquires the uniformly transmitted device ids of the plurality of first neighboring ues in an asynchronous transmission manner. The asynchronous sending method uniformly sends the relevant information to the base station, so that the base station can be prevented from continuously establishing synchronous connection with the user equipment 10, the frequency of receiving equipment identification codes can be reduced, channel resources are saved, and the electric quantity loss of the user equipment 10 is reduced.

For more clear explanation, reference may be further made to fig. 11, and fig. 11 is a schematic diagram of data interaction of another embodiment of the method for receiving the device identification code according to the present invention.

As shown in fig. 11, the ue sends a pilot signal to the base station through a shared channel broadcasted by the base station, where the pilot signal carries a pilot identifier. After receiving the pilot signal, the base station sends a discovery target report message to the user equipment through a shared channel, wherein the discovery target report message comprises an ACK/NACK indicator bit and the pilot identifier. And after receiving the discovery target report message, the user sends an MAC PDU packet to the base station through a shared channel. And after receiving the MAC PDU packet, the base station sends ACK response information to the user equipment through the shared channel.

It should be noted that, in an alternative embodiment of the present invention, the user equipment may generate a plurality of MAC PDU packets, and at this time, the user equipment sets an indication bit in a header of the MAC PDU packet, where the indication bit is used to indicate whether the MAC PDU packet is a last data packet. After receiving the MAC PDU packet, the base station further detects whether the indication bit is set, if so, the base station indicates that the MAC PDU packet is the last data packet sent by the user equipment, and at the moment, the base station can send ACK response information to the user equipment. If not, the MAC PDU packet is not the last data packet sent by the user equipment, and the ACK response information is not sent to the user equipment until the last MAC PDU packet is received.
