Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a terminal voice service connection method, apparatus, device, and computer-readable storage medium.
Background
Currently, the chinese telecommunication SA (independent networking) network does not support voice services vonr (voice Over nr) operating in the 5G frequency band for the moment, and when a 5G terminal user has a voice demand, the terminal user needs to fall back to an LTE (Long Term Evolution ) network in an EPS FB manner to complete a voice service in a VoLTE manner. The EPS FB means that the voice service falls back from 5G to 4G under the condition that 5G does not have the VoNR condition, and the continuity of the voice service is ensured by means of volte (voice over lte).
At present, in an existing LTE network, when a 5G terminal performs LTE network attachment (Attach), after attachment fails for 5 times due to poor cell signal or temporary cell failure, the terminal starts a T3402 timer (default for 12 minutes) according to protocol planning, and the terminal can be restarted after temporarily turning off an LTE module for 12 minutes. If the terminal successfully attaches to the SA network within 12 minutes, LTE signals in the area are improved or a temporary failure cell is recovered. However, at this time, since the LTE module of the terminal is turned off, the terminal cannot fall back to LTE to use the VoLTE voice service in the EPS FB manner.

2) After detecting the Msg1 message, the eNB (base station) sends a random access response message, Msg2 message, to the UE.
3) And after receiving the random access response, the UE adjusts the uplink sending time according to the TA (Tracking Area) of the Msg2 and sends an RRC Connection Request message to the eNB for establishing RRC Connection.
Wherein, the RRC Connection Request message is a radio resource control Connection message.
4) The eNB sends an RRC Connection Setup message to the UE, including establishment of SRB1 signaling bearer information and radio resource configuration information. SRB1 is the communication interface between LTE eNB and EPC (core network).
