Embodiment Construction

[0128] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0129] Currently, in the description of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), a new generation of mobile communication systems (such as the fifth generation mobile communication system 5G) needs to provide mobility support with different requirements. Because there are different communication scenarios in the 5G network: different UEs have different mobile paradigms, for example, some terminals access the network while moving at high speed, while others access the network nomadicly or statically; different business It also has different mobility support requirements. For example, some services want to reduce the interruption and packet loss rate during service transmission, so the network is required to shield the ...

Abstract

The invention provides a session management method, a mobility management function and a session management function. The method comprises the following steps: the mobility management function determines whether a user terminal UE moves out from an allowed area; if the UE moves out from the allowed area, the mobility management function determines a management request of a session of the UE; the mobility management function sends the management request to a session management function that serves the UE, wherein the management request is used for requesting the session management function to the manage the session of the UE. In this way, when the UE moves out from the allowed area, the session of the UE is deleted, switched or updated in time, thereby avoiding unnecessary data issue so asto reduce the waste of connection resources.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a session management method, a mobility management function and a session management function. Background technique [0002] In the future, the mobile communication network needs to support richer network applications, adapt to the business needs of various scenarios, and meet the service performance requirements of different user terminals UE. In order to improve network resource utilization, on-demand mobility management is proposed in future mobile communication networks, and different mobility supports are provided based on different characteristics of UEs and services. [0003] The on-demand mobility management defines different levels of mobility restrictions (mobility levels), such as no mobility (No mobility), limited mobility (Limited / low mobility), and unlimited mobility (Unlimited mobility). In the definition of Limited / low mobility, it is required to provide t...
