Problems solved by technology

However, when the UE triggers the fallback to the CS domain through the ESR message, the ESR message will be suspended, and the UE will repeatedly send the ESR message
Repeated sending of ESR messages by the UE may cause the UE to fall back to the CS domain again, making it difficult for the UE to use business data normally on LTE

Embodiment Construction

[0047] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0048] In related technologies, network operations of major operators can gradually implement voice and video calls through IMS. However, in terms of the coverage of voice and video calls, compared with the LTE and CS domains, the coverage of the CS domain is still relatively large. Therefore, the CS domain is still an important supplement in terms of voice calls.

Abstract

The invention relates to a call processing method, a call processing device and a storage medium. The call processing method is applied to the terminal, and the method comprises the following steps: determining that a circuit switched fallback CSFB call establishment process of the terminal is stopped and a radio resource control RRC connection release message redirected to a circuit switched domain is received, and determining a current communication state of the CSFB call; and in response to determining that the current communication state of the CSFB call meets the condition of cancelling an extended service request ESR message retransmission mechanism, cancelling sending of the current to-be-retransmitted ESR message. Through the method and the device, the problem that the UE cannot normally use LTE (Long Term Evolution) to surf the Internet at a high speed due to the fact that the UE falls back to the CS domain for multiple times due to retransmission of the ESR message can be avoided.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a call processing method, a call processing device, and a storage medium. Background technique [0002] In related technologies, major operators implement voice and video calls through an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS). However, in terms of the coverage of voice and video calls, compared with the Long Term Evolution (LTE) technology and the Circuit Switched (CS) network (also referred to as the CS domain), the coverage of the CS domain is relatively larger. [0003] When the user equipment (User Equipment, UE) is registered in LTE through joint registration and has not registered to carry voice services through long-term evolution (Voice over Long-Term Evolution, VoLTE), or the UE does not support VoLTE, or the current public land When the mobile network (Public Land Mobile Network, PLMN) does not support VoLTE, it needs to fall back ...
