As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Fig. 1 is a flowchart of a communication method according to an embodiment of the present application. As shown in fig. 1, the communication method may include:

step 101, the access network device sends first indication information to the core network device to indicate that the first user equipment is located in the first customer premise network CPN.

Taking an indoor communication scenario as an example, fig. 2 shows a flow chart of establishing a data communication link.

As shown in fig. 2, before the first user equipment performs data communication with any user equipment, a service request message may be sent to the access network equipment, and then the access network equipment sends the service request message to the core network equipment.

In the embodiment of the present application, the access network device may include a base station and a gateway. Specifically, first, the first user equipment may send a service request message to the accessed base station. The base station accessed by the first user equipment can be any indoor base station. Illustratively, it may be a Premises Radio Access Station (PRAS).

Then, after receiving the service request message, the base station may forward the service request message to a corresponding gateway. In this embodiment of the application, the Gateway corresponding to the first user equipment may be any Residential Gateway related to an indoor communication scenario, and may be, for example, an Evolved Residential Gateway (edrg).

Finally, the gateway may send the received service request message to the core network device.

Further, in an indoor communication scenario, when a user equipment accesses different access Network devices, the user premise networks (CPNs) to which the user equipment belongs are different.

Based on the above description, in order to identify the CPN where the first user equipment is located, in the embodiment of the present application, the first indication information may be added to the service request message. The first indication information is used for indicating that the first user equipment is located in the first CPN. The first indication information may be a CPN indication, or a local communication indication. The first indication information may also be any information capable of uniquely identifying the CPN, and may be, for example, an access network device identifier, and may also be a CPN identifier, which is not limited in this application.

In a possible implementation manner, the first indication information may be added to the service request message by the first user equipment. Specifically, the first user equipment may receive a cell broadcast transmitted by the base station. If the first user equipment determines to access the CPN network according to the cell broadcast, the first indication information can be added into the service request message according to the cell broadcast. Or, the first user equipment adds the first indication information in a Non Access Stratum (NAS) message sent to the core network device.

In another possible implementation manner, the base station accessible by the first user equipment adds the first indication information to the information including the service request message. Specifically, the base station to which the first user equipment is accessed may add the first indication information to the information including the service request message after receiving the service request message. Wherein, the information containing the service request message may be an N2 interface message.

In another possible implementation manner, the gateway corresponding to the first user equipment may add the first indication information to the information including the service request message. Specifically, after receiving the service request message, the gateway may add the first indication information to the information including the service request message.

Step 102, the core network device receives first indication information sent by the access network device.

In the embodiment of the application, the core network device may receive a request message sent by the access network device, and acquire the first indication information carried therein. Thus, the core network device may determine that the first user equipment is located in the first CPN according to the first indication information.

Further, the core network device may also page a corresponding second user equipment according to the service request message of the first user equipment.

As shown in fig. 2, after receiving the service request message, the core network device may determine a corresponding second user equipment according to the service request message. A paging message may then be sent to the second user equipment to trigger a traffic response for the second user equipment.

After receiving the paging message sent by the core network device, the second user device, similar to the first user device, may send a service response message to a gateway corresponding to the second user device through a base station to which the second user device is connected. Then, the gateway corresponding to the second user equipment may send the service response message to the core network device. Therefore, the core network device may determine the CPN where the second user equipment is located according to the access network device identifier or the CPN identifier carried in the service response message.

In this embodiment, the core network device may be, for example, a User Plane Function (UPF) network element, an Access and Mobility Management Function (AMF) network element, a Session Management Function (SMF) network element, and the like.

Step 103, the core network device sends second indication information to the access network device, so as to indicate the first user equipment to perform local communication in the first CPN.

In this embodiment, the core network device may determine whether the CPN where the second user equipment is located is the same as the CPN where the first user equipment is located. After determining that the second user equipment is also located in the first CPN, the first user equipment and the second user equipment may be considered to access the same gateway. At this time, the core network device may send the second indication information to the gateway. The second indication information may indicate that the first user equipment is in local communication in the first CPN.

In an embodiment of the present application, the second indication information may include: the first user equipment information and the second user equipment information are locally communicated in the first CPN, and/or the service information of the first user equipment and the service information of the second user equipment are locally communicated in the first CPN. The first user equipment information and the second user equipment information may include, but are not limited to: transport layer information, user equipment interface identification, identification of user equipment, and the like.

Wherein the user equipment interface identification comprises: NG interface Application Protocol ID (ngapplication Protocol ID). The identifier may be an Application Protocol identifier of an NG interface of a Network Protocol (Action Message Format UE NG Application Protocol ID, AMF UE NGAP ID), or an Application Protocol identifier of an NG interface of a radio Access Network (Wireless Access Network UE NG Application Protocol ID, RAN UE NGAP ID).

The Transport Layer Information may be user plane Transport Layer Information (UP Transport Layer Information, UP TLI). The GPRS Tunneling Protocol (GPRS GTP) information may include a transport layer address, a Tunnel end Identifier (GTP-TEID), a port number, and the like.

The identity of the user equipment may be a Cell-Radio Network Temporary identity (C-RNTI). Alternatively, the Temporary UE Identifier may be 5G globally Unique (5G global Unique Temporary UE identity,5G-GUT I), 5G Temporary Mobile Subscription Identifier (5G S-Temporary Mobile Subscription Identifier, 5G-S-TMSI), subscription Permanent Identifier (SUPI), or the like.

The service information may include a Protocol Data Unit Session Identifier (PDU Session ID) of the ue, or one or more Flow identifiers (Flow IDs) and the like.

And 104, the access network equipment receives the second indication information and determines that the first user equipment carries out local communication in the first CPN.

In the embodiment of the application, after receiving the second indication information sent by the core network device, the gateway may determine that the first user equipment performs local communication in the first CPN. Thereafter, the gateway may determine the base stations accessed by the first user equipment and the second user equipment respectively according to the second indication information. Then, a local transmission link of the first user equipment in the first CPN may be determined according to the base stations accessed by the first user equipment and the second user equipment.

In a possible implementation manner, the gateway determines that the first user equipment and the second user equipment access different base stations respectively. Then, determining a traffic data path between the first user equipment and the second user equipment may comprise: the system comprises a gateway, a first base station and a second base station.

At this time, the gateway may send the user equipment information and the service information to the first base station to which the first user equipment is accessed and the second base station to which the second user equipment is accessed, respectively. In this regard, the embodiments of the present application may provide several possible implementations.

In a first mode

The gateway may send the first user equipment information and/or the service information of the first user equipment to the first base station to which the first user equipment is accessed. And sending the second user equipment information and/or the service information of the second user equipment to a second base station accessed by the second user equipment. Thus, the first base station and the second base station can determine the user equipment for local communication and the service for performing local communication.

Mode two

The gateway can respectively send local communication instructions to the first base station and the second base station through the special transmission channel of the user equipment, and does not send user equipment information and service information. Thus, the first base station and the second base station can determine the user equipment information for performing the local communication according to the user equipment-specific transmission channel. And the first base station and the second base station may determine all services performed by the first user equipment and the second user equipment as services performed in a local communication manner.

Mode III

The gateway may send only the first user equipment information to the first base station and the second user equipment information to the second base station without sending traffic information. The first base station and the second base station may determine all services performed by the first user equipment and the second user equipment as services performed in the local communication manner.

Mode IV

The gateway can send the service information of the first user equipment to the first base station and send the service information of the second user equipment to the second base station through the special transmission channel of the user equipment. Thus, the first base station and the second base station can determine the user equipment performing local communication according to the user equipment-specific transmission channel. And determining the service for local communication according to the received service information.

Mode five

The gateway may forward the received second indication information to the first base station and the second base station, respectively. Therefore, the first base station and the second base station can determine the user equipment performing local communication and the corresponding service according to the second indication information.

It should be noted that the service information of the ue may be identified by an associated Radio Bearer Identifier (RBI), or may be identified by a Logical Channel Identifier (LCI).

Further, the gateway may also send data transmission address information to the first base station and the second base station, respectively. The data transmission address information is used for the first base station and the second base station to respectively establish a local transmission channel with the gateway. Therefore, the service data between the first user equipment and the second user equipment can be transmitted through the local transmission channel without passing through the core network.

In consideration of cell handover of the first user equipment and the second user equipment in a mobile communication scenario, the gateway may further send the second user equipment information, and/or the second base station information to the first base station. Thus, when performing cell handover, the first base station can perform cell handover with the second base station as a preferred target base station according to the received information. Correspondingly, the gateway can also send the first user equipment information and/or the first base station information to the second base station. Thus, when performing cell handover, the second base station may perform cell handover with the first base station as a preferred target base station according to the received information.

It should be noted that, when performing cell handover, the first base station and/or the second base station may carry the local communication indication and/or the service information of the local communication in the handover request sent to the target base station. Thus, the target base station can be made to determine the user equipment performing the local communication, and the service performing the local communication. Meanwhile, a transmission channel for local transmission with the gateway can be switched from the first base station and/or the second base station to the target base station.

After the cell handover is completed, the first base station and/or the second base station may further send fourth indication information to the core network device. The fourth indication information may be used to inform the first user equipment and/or the second user equipment to maintain local communication after switching cells.

In another possible implementation manner, the gateway determines that the first user equipment and the second user equipment access the same base station respectively. Then, determining a traffic data path between the first user equipment and the second user equipment may comprise: and the first user equipment and the second user equipment access the base station.

At this time, the gateway may send the first user equipment information and/or the service information of the first user equipment, and the second user equipment information and/or the service information of the second user equipment to the base station. Thus, the base station can determine two user equipments performing local communication and a service in which the two user equipments perform local communication.

Further, after receiving the information, the base station may further send third indication information to the first user equipment and the second user equipment. The third indication information is used for indicating the first user equipment to directly communicate with the second user equipment. It should be noted that, at this time, the first user equipment and the second user equipment may still maintain the connection with the base station. When the transmission quality of the direct communication link between the first user equipment and the second user equipment is difficult to support direct communication, the direct communication link can be quickly switched to a transmission link between the first user equipment and the base station, and local communication is carried out through the base station.

In the above technical solution, the access network device may send the first indication information to the core network device to indicate that the first user equipment is located in the first customer premise network CPN. The core network device may send and receive second indication information to the access network device according to the first indication information, so as to indicate the first user equipment to perform local communication in the first CPN. By the technical scheme, the data transmission path between the user equipment can be shortened, the communication time delay is reduced, and the communication efficiency is improved.

Fig. 3 is a flowchart of another communication method according to an embodiment of the present application. As shown in fig. 3, the communication method may include:

step 201, the access network device sends first indication information to the core network device to indicate that the first user equipment is located in the first customer premise network CPN.

Step 202, the core network device receives the first indication information sent by the access network device, and pages the corresponding second user equipment.

Step 203, the core network device receives a service response message sent by the second user device, where the service response message includes a CNP identifier corresponding to the second user device.

Step 204, the core network device determines that the second user equipment is located in the first CPN according to the CPN identifier, and sends second indication information to the access network device to indicate that the first user equipment performs local communication in the first CPN.

In step 205, the gateway determines whether the base stations accessed by the first user equipment and the second user equipment are the same in response to the second indication information. If so, go to step 206; otherwise, step 207 is performed.

Step 206, the gateway determining the service data path between the first user equipment and the second user equipment includes: the system comprises a gateway, a first base station accessed by first user equipment and a second base station accessed by second user equipment.

In the embodiment of the application, if the base stations accessed by the first user equipment and the second user equipment are different, the first user equipment and the second user equipment can upload the service data to the respective accessed base stations and upload the service data to the gateway through the base stations when the service data communication is performed by the first user equipment and the second user equipment. Then, the gateway can directly send the received service data to the base station of the opposite terminal user equipment without passing through the core network. Thus, the data transmission path can be shortened.

Step 207, the gateway determines that the service data path between the first user equipment and the second user equipment includes: and the first user equipment and the second user equipment access the base station.

In the embodiment of the application, if the base stations accessed by the first user equipment and the second user equipment are the same, the first user equipment and the second user equipment can send service data to the accessed base station when performing service data communication, and further, the base station can directly send the service data to opposite-end user equipment without passing through a gateway and a core network. Therefore, the data transmission path between the user equipment can be greatly shortened, the transmission time delay can be effectively reduced, and the communication efficiency is improved.

Further, the base station may also send third indication information to the first user equipment and the second user equipment. The third indication information is used for indicating the first user equipment to directly communicate with the second user equipment. Illustratively, a direct communication interface PC5 path can be established between the first user equipment and the second user equipment, so as to realize direct communication. Therefore, the first user equipment and the second user equipment can directly send the service data to the opposite-end user equipment through the data direct connection path.

In communication scenes such as indoor communication and outdoor small base station coverage, the technical scheme provided by the embodiment of the application can further shorten the data transmission path between the user equipment when the base stations accessed by the first user equipment and the second user equipment are the same, thereby effectively reducing communication time delay and improving communication efficiency.
