US 2020/0221540 A1 · COMMUNICATION METHOD, APPARATUS, AND SYSTEM

Abstract

A communication method, an apparatus, and a system in which a first session management function entity based on information of a terminal group determines user plane function entities accessed by terminals in a terminal group, and the first session management function entity determines a target user plane function entity based on the user plane function entities, where the target user plane function entity is used to perform communication between terminals in the terminal group. According to the method, the terminals in the terminal group are redirected to a same user plane function entity, namely, the target user plane function entity, so that communication between the terminals in the terminal group is locally implemented in the target user plane function entity. This shortens a communication path, and reduces a communication latency.

Claims20

Dependent claims

A communication method, comprising:

determining, by a first session management function entity based on information of a terminal group, user plane function entities accessed by terminals in the terminal group;
and
determining, by the first session management function entity, a target user plane function entity based on the user plane function entities;
and
performing, by the target user plane function entity, communication between the terminals in the terminal group.

2 more elements

A communication system, comprising:

a first session management function entity;
and
a target user plane function entity;
wherein:
the first session management function entity is configured to determine, based on information of a terminal group, user plane function entities accessed by terminals in the terminal group;
and determine the target user plane function entity based on the user plane function entities;
and
the target user plane function entity is configured to perform communication between the terminals in the terminal group.

5 more elements

A first session management function entity, comprising:

at least one processor, and a memory storing computer-executable instructions;
wherein the computer-executable instructions, when executed by the at least one processor, further cause the first session management function entity to:
determine, based on information of a terminal group, user plane function entities accessed by terminals in the terminal group;
and
determine a target user plane function entity based on the user plane function entities, wherein the target user plane function entity is used to perform communication between terminals in the terminal group.
