And 102, if the indication information is not received, the terminal acquires pre-stored frequency point information.
And 103, the terminal resides in the target network based on the frequency point information.
In one embodiment, the target network comprises a 5G NR network or the like. When the terminal registers to the 5GNR network, the terminal stores frequency point information corresponding to the 5G NR network. And if the indication information is not received, the terminal resides in the 5G NR network based on the frequency point information corresponding to the 5G NR network.
The method for the terminal to return to the network independently can return to the 5G NR network without depending on network signaling redirection or reselection, and after the terminal finishes the call, the terminal reads the stored frequency point list information, can quickly return to the 5G NR network, and can improve the 5G experience of the user in the initial stage of 5G network deployment under the condition that the coverage and optimization of the 5G network are not complete.
In one embodiment, the voice call service includes VoLTE call service, and the like. And the terminal dials or answers the voice call and falls back to the LTE network in an EPS FALLBACK mode to carry out the VoLTE communication service. And the terminal receives a Radio Resource Control (RRC) release message from the LTE cell in response to the termination of the VoLTE call service after the VoLTE call service is terminated.
The terminal judges whether the RRC release message carries indication information or not, wherein the indication information comprises key directional frequency point information and the like. Or, the terminal determines whether the RRC release message does not carry the key-oriented frequency point information, and then determines whether the LTE cell broadcasts the SIB24 message. If the terminal receives the SIB24 message broadcasted by the LTE cell, the terminal judges whether the SIB24 message carries indication information, wherein the indication information comprises the neighbor cell information of the LTE cell and the like, and the neighbor cell of the LTE cell comprises a 5G cell in an SA networking mode and the like. And the terminal resides in the 5G NR network based on the received key frequency point information or the adjacent cell information of the LTE cell.
And the terminal registers to the 5G NR network and records the current NR frequency point information. When a call is dialed, the terminal falls back to the LTE network in an EPS FALLBACK mode, and a VoLTE voice service is established. When the voice call is finished, the terminal receives a radio resource control RRC release message from the current network, when the radio resource control RRC release message does not contain redirection information, the terminal still resides in the LTE network, the terminal tries to read the SIB24 message, and the current cell does not issue the SIB24, the terminal reads the previously recorded 5G frequency point information, actively searches the 5G frequency point, and then quickly returns to the 5G network. The terminal can create a list, retain a plurality of resident 5G NR frequency point information, and sequentially search the frequency points in the stored list one by one to ensure that the frequency points are correctly returned to the 5G NR network.
The method for the terminal to return to the network autonomously can still ensure that the terminal can return to the 5G network quickly under the condition that the network is not configured with the redirection instruction or SIB24 message, so as to ensure the 5G physical examination of the user.
Fig. 2 is a flowchart illustrating another embodiment of a method for a terminal to autonomously return to a network, as shown in fig. 2:
Instep 205, if the RRC release message carries an emphasis frequency point, the process goes tostep 208, and then goes tostep 206.
Instep 206, if the current LTE cell broadcasts the SIB24 message, the terminal will reselect according to the SIB24 neighbor message, and go tostep 208, if the current LTE cell does not broadcast the SIB24 message, go tostep 207.
Instep 207, the terminal reads the frequency point recorded instep 201 or the frequency point where the NR network resides before to reside in the NR network.
And step 208, returning to the 5G SA network.
The method for the terminal to return to the network independently disclosed by the invention returns to the 5G NR network in a mode of not depending on redirection issued by the network or SIB24 message, and quickly and independently returns to the 5G NR network by reading the frequency points stored by the terminal.

The resident processing module 33 resides in the 5G NR network based on the frequency point information corresponding to the 5G NR network.
The voice call service includes a VoLTE call service, and the like, and the call processing module 35 dials or answers a voice call, and falls back to the LTE network in an EPS call mode to perform the VoLTE call service. After the VoLTE call service is terminated, the indication determining module 31 receives a radio resource control RRC release message from the LTE cell in response to the termination of the VoLTE call service, and determines whether the RRC release message carries indication information, where the indication information includes key directional frequency point information and the like.
