Problems solved by technology

Since the 4G / 5G IMS network and the traditional 2G / 3G network belong to different network and service systems, this leads to some special numbers and telephone service services under the 2G / 3G network, such as the customer service number starting with 955 in the banking system , cannot be connected under the IMS network

Embodiment Construction

[0062] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. Rather, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0063] Based on the problems in the background art, a common solution is: for some special numbers, calls cannot be reached under the IMS network. All the terminals do not make any judgments, and directly call out through VoLTE. However, because the IMS network does not support such special numbers, the network will return an error code to the terminal and end the VoLTE call. The terminal can th...

Abstract

The invention provides a call method, apparatus and device. The method comprises the following steps: when a user inputs a number on an interface to make a call, obtaining a call request, detecting whether a to-be-called number exists in a pre-obtained special number list, wherein the special number list comprises at least one number that cannot be called by adopting the 4G or 5G network, if the to-be-called number exists in the special number list, switching the network to the 2G or 3G network, and establishing a call with the to-be-called number through the 2G or 3G network. The problem that a part of special numbers cannot be called by the IMS network is solved, the normal establishment of the call is ensured by selecting the matched network according to the call number, and the call establishment time is shortened, therefore the user experience is improved.

Description

Technical field [0001] The present disclosure relates to computer technology, and in particular to a method, device and equipment for calling. Background technique [0002] At present, operators are deploying IP Multimedia Subsystem (IMS) networks under 4G / 5G to support IMS-based voice services (Voice over LTE, VoLTE) voice calls directly under 4G / 5G networks. An IP data transmission technology that does not require a 2G / 3G network, and all services are carried on a 4G / 5G network, which can realize the unification of data and voice services under the same network. In other words, the 4G / 5G network not only provides high-speed data services, but also provides high-definition voice and video call services based on VoIP and Long Term Evolution (Long Term Evolution, LTE) technology. As the 4G / 5G IMS network and the traditional 2G / 3G network belong to different networks and business systems, this leads to some special numbers and telephone service services under the 2G / 3G network, su...
