Embodiment Construction

[0040]The method for allocating bearer identifiers provided in this embodiment of the application can be applied to such as figure 1 As shown in the communication system, the communication system includes a terminal 10 , an access network device 11 and a core network device 12 . Wherein, the core network equipment includes SMF and AMF, AMF can be used to allocate EBI for the terminal, and SMF can be used to manage the session established by the terminal. The above-mentioned terminal 10 is a converged terminal, that is, a terminal that can support 5G and 4G network standards. Optionally, the above-mentioned terminal 10 may be a smart phone, a tablet computer, a smart watch, a fitness tracker, a virtual reality device, an Internet of Things sensor, and the like.

[0041] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. I...

Abstract

The invention provides a bearer identifierallocation method, a device, a session management network element, an access and mobility management network element and a storage medium. The method comprises the steps: transmitting an EBI distribution request message to an AMF when a current session is created for a terminal; receiving a PDU session update message sent by the AMF, wherein the PDU session update message comprises information of a session to be preempted; when it is determined that the to-be-preempted session cannot be processed, sending a first PDU session update response message to the AMF, wherein the first PDU session update response message comprises a first reason value that the to-be-preempted session cannot be processed, and the first reason value is used for indicating that the AMF successfully preempts an EBI of the to-be-preempted session; and assigning the EBI to the current session. Compared with the prior art, the method improves the success rate of EBI distribution.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for allocating a bearer identifier, a session management network element, an access and mobility management network element, and a storage medium. Background technique [0002] With the official commercialization of the 5th generation (5th Generation, 5G) network, 5G network will appear in our daily life. However, in the initial stage of 5G network commercialization, limited by the maturity of technology and the support of terminal equipment, 5G network cannot cover a large area, and 5G network and 4th Generation (4G) network will coexist for a long time. a period of time. In this networking situation, there will be interoperability between the 5G network and the 4G network. Therefore, when creating a session in 5G, the Session Management Function (SMF) needs to report to the access and mobility management network in advance. The element (Access and M...
