RRC state transition method and device, and storage medium

Abstract

The invention discloses an RRC state transition method, which comprises the following steps of: recording N time differences of UE from a first state to a connected state within a preset time; adopting a preset method for the N time differences to obtain a first value; comparing the first value with a preset threshold to judge whether the UE frequently enters a connected state; if so, configuring the NG interface to carry an RRC inactive state assistance information cell; and sending the RRC inactive state assistance information cell, so that after a base station receives the RRC inactive state assistance information cell, the UE is converted into an inactive state when the UE is released. According to the RRC state transition method, the UE which frequently accesses the network is decided to enter the RRCINACTIVE state, so that the UE can quickly recover connection when accessing the network next time, and the UE which does not frequently access the network is converted into the idle state, and the waste of network resources is not caused.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device and storage medium for RRC state transition. Background technique [0002] In the R13 version of the 3GPP protocol, LTE RRC (Radio Resource Control, Radio Resource Control) introduces a new RRC state, that is, the RRC_INACTIVE state (inactive state), and the RRC_INACTIVE state introduced by R13 is continued in the 5G R15 specification. In this state, the Uu interface of the UE (User Equipment, user equipment) is disconnected, but the connection with the CN (Core Net, core network) is maintained, and the UE and the network still maintain context information, so that the UE returns to the connected state It's fast. Therefore, for a UE that frequently accesses the network, it will be a better experience to be able to quickly return to the connected state from other states. Moreover, the Uu interface connection of the UE in the RRC_INACTIVE stat...

AI Technical Summary

Problems solved by technology

However, the purpose of introducing the RRC_INACTIVE state in the protocol is mainly to quickly restore the connection, which is not applicable to all UEs.

For UEs that need to access the network frequently, it can indeed benefit from increasing the access speed. On the contrary, for UEs that only access the network once for a long time, entering the RRC_INACTIVE state will only waste network resources.
