Problems solved by technology

[0006] However, as the number of V2X ASs increases in the future, the types of applications provided by V2X ASs increase, or the number of V2X terminals accessing the network increases, there will not only be a large number of signaling resources for all V2X terminals to configure the V2X AS information corresponding to each application Consumption, may also expose the location of V2X AS, involves security issues, and is very inefficient and complicated

Embodiment 1

[0292] This application provides a communication method such as Figure 6 As shown, the method may include:

[0293] S601. AF creates a request message.

[0294] Specifically, when the AF initiates service creation of the first service or modifies or deletes an existing service request of the first service, S601 is executed. The content of the request message includes: the address information of the AF (IP address or FQDN address or others), the service identifier of the first service provided by the AF (optionally also including the location information corresponding to the first service provided by the AF (which can be coordinate information, Or the GEO ID divided by the network side)).

[0295] Optionally, the request message may also include an operation identifier for identifying the operation. For example, the operation ID can be AF Transaction ID.

[0296] Exemplarily, the request message may be a service flow creation message (for example, Nnef_TrafficInfluence_Cre...

Embodiment 2

[0333] This application proposes another communication method, such as Figure 7 As shown, the method may include:

[0334] S701. AF creates a request message.

[0335]Specifically, for the implementation manner of S701, reference may be made to the description of S601, and the specific implementation will not be repeated here.

[0336] S702. The AF sends a request message to the PCF.

[0337] Specifically, for the implementation manner of S702, reference may be made to the description of S602, and details will not be repeated for specific implementation.

[0338] S703. The PCF determines the first address.

[0339] Wherein, the first address is used for the UE to send the data packet of the first service to the UPF.

[0340] Specifically, for the implementation manner of S703, reference may be made to the description of S605, and the specific implementation will not be repeated here.

[0341] The PCF binds the first address and the received service identifier of the firs...

Embodiment 3

[0356] This application provides another communication method such as Figure 8 As shown, the method may include:

[0357] S801. The AF determines the first address.

[0358] Wherein, the first address is used for the UE to send the data packet of the first service to the user plane functional network element.

[0359] Specifically, when the AF initiates the service creation of the first business or modifies or deletes the existing first business service request, it executes S801.

[0360] It should be noted that, for the determination process in S801, reference may be made to the specific process in S605, which will not be repeated here.

[0361] S802. The AF sends a request message to the PCF.

[0362] The content of the request message includes: the correspondence between the service identifier of the first service of the AF and the first address, the correspondence between the first address and the address information of the AF (optionally may also include the location ...

Abstract

An embodiment of the invention discloses a communication method, device and system, relates to the field of communication, and realizes efficient, simple, resource-saving and high-security service data transmission in a server localization scene. The communication method specifically comprises the steps that: a first network element determines a first address, wherein the first address is an address of a data packet of a first service sent by user equipment to a user plane function network element; and the first network element sends a corresponding relation between address information of a first server providing the first service and the first address to the user plane function network element, wherein the address indicated by the address information of the first server is the address ofthe data packet sent to the first server by the user plane function network element.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a communication method, device, and system. Background technique [0002] In order to enrich the functions of the mobile cellular network, the 3rd generation partnership project (3rd generation partnership project, 3GPP) added support for the V2X communication of the Internet of Vehicles in the Release 14 version. In the fifth generation mobile communication system (5th generation, 5G), V2X communication can support more car networking application scenarios, such as: vehicle teaming, sensor expansion, remote driving and automatic driving enhancement, etc. [0003] In V2X communication, V2X application server (V2X application server, V2XAS) provides services to V2X terminals (vehicles or terminals installed in vehicles). Video information obtained by surveillance cameras, etc. Such as figure 1 The shown network architecture shows that the V2X AS is dep...
