Problems solved by technology

[0004] However, when the connection between the UE and the radio access network is disconnected, for some specific network-initiated modification procedures or session modification commands that do not need to be synchronized to the UE in time, the above information synchronization process will cause additional signaling overhead

Abstract

The present application provides an information processing method and device, the method comprising: a network device receives a first message, the first message includes first information sent to a terminal device, and the first information is information that can be delayed in sending; When the network device determines that the terminal device is in an RRC inactive state, storing the first information; when the terminal requests to establish a wireless connection, the network device sends the first information to the terminal device . The method and corresponding apparatus can be used to reduce signaling overhead.

Description

technical field [0001] The present application relates to communication technologies, and in particular to an information processing method and device. Background technique [0002] An Evolved Packet System (EPS for short) session is a connection based on an Internet Protocol (IP for short), and is specifically an association between a User Equipment (UE for short) and an IP network. Wherein, an EPS session is composed of one or more IP-Connectivity Access Network (IP-Connectivity Access Network, referred to as IP-CAN) bearers (that is, EPS bearers). ) between one or more logical sets of service data flows, including three parts: radio bearer, S1 bearer and S5 / S8 bearer. [0003] In the above-mentioned EPS session management process, modification of the context of the EPS bearer is often involved. The UE and core network nodes, PGW, and Serving GateWay (SGW for short) need to synchronize the context of the EPS session, that is, to ensure that the context information of the...
