Problems solved by technology

[0003] In CSFB mode, when the user equipment (User Equipment, UE) as the mobile originator (Mobile Origination, MO) returns to the GSM cell when making the original call, if the CM_SERVICE_REQUEST is rejected by the network, it will cause 100% MO call failure, and Subsequent MO calls that fall on the problematic GSM cell all fail, thereby reducing the call success rate

Embodiment 1

[0035] like figure 1 As shown, information processing methods include:

[0036] Step 101: Receive a redirection message sent by the network side, where the redirection message includes a frequency point list with at least one frequency point;

[0037] Step 102: Obtain a pre-stored set of abnormal frequency points; wherein, the set of abnormal frequency points contains at least one abnormal frequency point;

[0038] Step 103: Based on the abnormal frequency point set and the frequency point list, determine at least one abnormal frequency point contained in the frequency point list.

[0039] Here, the execution subject of step 101 may be the communication unit of the terminal device, and the execution subject of steps 102 and 103 may be the processing unit of the terminal device.

[0040] In actual application, when the mobile terminal is in CSFB mode as a mobile calling party (Mobile Origination, MO) or a mobile called party (Mobile Termination, MT), when falling back from LT...

Embodiment 2

[0061] In order to better reflect the purpose of the application, the embodiment of the application is further illustrated, as figure 2 As shown, the method specifically includes:

[0062] Step 201: When receiving a rejection message from the network side, determine the abnormal frequency point and its corresponding first cell ID; update the abnormal frequency point set by using the abnormal frequency point and its corresponding first cell ID;

[0063] Here, step 201 implements the failure process of the first CSFB MO call. like image 3 As shown, the terminal equipment includes a mobility management component (MM) and a GSM component submodule (GRR). The first CSFB MO call failure process is as follows:

[0064] 1. During the redirection process, the MM sends a service request message CM_SERVICE_REQUEST to the network side through the GRR;

[0065] 2. GRR forwards the rejection message CM_SERVICE_REJECT sent from the network side to MM; here, the cause value of the rejec...

Embodiment 3

[0082] In order to better reflect the purpose of the application, the embodiment of the application is further illustrated, as Figure 4 As shown, the method specifically includes:

[0083] Step 401: When receiving a rejection message from the network side, determine the abnormal frequency point and its corresponding first cell ID; update the abnormal frequency point set by using the abnormal frequency point and its corresponding first cell ID;

[0084] Here, step 401 implements the failure process of the first CSFB MO call. like image 3 As shown, the terminal equipment includes a mobility management component (MM) and a GSM component submodule (GRR). The first CSFB MO call failure process is as follows:

[0085] 1. During the redirection process, the MM sends a service request message CM_SERVICE_REQUEST to the network side through the GRR;

[0086] 2. GRR forwards the rejection message CM_SERVICE_REJECT sent from the network side to MM; here, the cause value of the rejec...

Abstract

The embodiment of the present invention discloses an information processing method, a terminal device, and a computer readable storage medium. The method is applied to the terminal device, and the method includes the steps: receiving a redirect message sent by a network side, wherein the redirect message includes a frequency point list with at least one frequency point; acquiring a pre-stored abnormal frequency point set, wherein the abnormal frequency point set includes at least one abnormal frequency point; determining at least one abnormal frequency point included in the frequency point list based on the abnormal frequency point set and the frequency point list.

Description

technical field [0001] The present application relates to circuit domain fallback technology, and in particular to an information processing method, a terminal device, and a computer-readable storage medium. Background technique [0002] The CSFB (Circuit Switched Fallback, Circuit Switched Fallback) solution directly utilizes the 2 / 3G network to provide voice services. The basic idea of ​​the CSFB solution is that when the terminal resides in the long-term evolution (Long Term Evolution, LTE) network idle state or data service connection state, when there is a voice service demand (calling or called), it will be assisted by the LTE network to fall back to the global The mobile communication system (Global System for Mobile Communication, GSM) network establishes a voice service, and quickly returns to the LTE network after the call is completed. [0003] In CSFB mode, when the user equipment (User Equipment, UE) as the mobile originator (Mobile Origination, MO) returns to ...
