Description

Communication connecting method, device, base station, terminal and computer readable storage medium

Technical field

The present invention relates to field of communication technology more particularly to a kind of communication connecting method, device, base station, terminal and calculating Machine readable storage medium storing program for executing.

Background technique

For the Dan Lian under eNB (evolved Node B, evolution base station) base station of 4G (4Generation, forth generation) Meeting UE (User Equipment, user terminal) can pass through when no any user data and signalling Suspend (hang-up) process discharges the 4G of the terminal UE Radio Link Radio Link that eats dishes without rice or wine, UE be in eat dishes without rice or wine it is inactive State Suspended (hang-up) state, UE still remains network side connection and services the UE of the still in store UE communication configuration of eNB at this time Context (context).See that UE is still within ECM_CONNECTED (EPS from CN (Core Network, core net) angle Connection management-CONNECTED, EPS Connection Management connected state) state, the phase of network side can be continued to execute Close process.Similarly, for the NG-RAN (Next in 5G (5Generation, the 5th generation mobile communcations system) Generation Radio Access Network, Next-Generation enter network) single connection UE under base station, is not appointing What when user data and signalling, the 5G of terminal UE can be eated dishes without rice or wine Radio Link Radio by Suspend process Link is discharged, and UE is in and eats dishes without rice or wine that (RadioResouceControl-INACTIVE's inactive state RRC_INACTIVE eats dishes without rice or wine Inactive state) unactivated state, UE still remains the in store UE communication configuration of network side connection and the service base station NG-RAN at this time Context.When the upstream data of UE reports to base station, by recovery request message of eating dishes without rice or wine by UE from inactive state of eating dishes without rice or wine RRC_INACTIVE unactivated state is restored to connected state.Recovery request of eating dishes without rice or wine message includes to restore mark to be convenient for identification of base stations UE Information simultaneously is restored to connect.

When the UE for the inactive state RRC_INACTIVE that eats dishes without rice or wine is moved to new base station range, UE context is still saved At former base station, new base station receive UE transmission eat dishes without rice or wine recovery request message when need according to restore mark in include base station believe Breath and end message obtain the context of UE to former base station.Since the capacity for recovery request message of eating dishes without rice or wine is limited, need to compress extensive Multiple mark (truncated resume Identity).Due to a variety of situations of network implementations, the compression for restoring mark is usually adopted With a variety of compressed formats, when former base station can not correctly identify compressed recovery mark, new base station will be unable to obtain from former base station The context of UE is taken, and then leads to not the connection for restoring UE.
