Embodiment 1

[0073] This embodiment relates to a method for implementing a call service. It is used to solve the above problems, so as to reduce the buffer resource consumption of the enhanced mobile switching center, reduce network signaling traffic, and at the same time ensure that the call service of the user terminal can be completed normally and quickly.

[0074] The implementation details of the method in this embodiment are described in detail below, and the following content is only for the convenience of understanding the implementation details of the solution, and is not necessary for implementing the solution.

Embodiment 2

[0086] Image 6 It is a flowchart of a method for implementing a call service in this embodiment, and the method can be applied to a device for implementing a call service, and the device can run on an eMSC. The second embodiment is roughly the same as the first embodiment, the main difference is that: when it is determined that the first state of the terminal is inconsistent with the second state, a registration request needs to be sent to the query call session control function entity in the IMS, so that the query call session The control function entity can reselect an S-CSCF entity for the terminal, that is, a second S-CSCF entity, which has completed related services of the terminal in the IMS domain.

[0087] The implementation method of the call service in this embodiment may include the following steps.

[0088] S610. Receive an initial call request sent by the terminal, and obtain a first state of the terminal in the enhanced mobile switching center.

Embodiment 3

[0110] Figure 7 It is a flow chart of the working method of the eMSC in this embodiment when performing the initial call service of the terminal, so as to realize the subscription notification mechanism independent of the registration state, and solve the first state of the ICS user on the eMSC and the second state of the ICS user on the IMS domain. The problem of inconsistency of status ensures that the initial call service process of the terminal can be carried out normally. The method may specifically include the following steps.

[0111] S701, the user terminal 7001 sends a local update request to the enhanced mobile switching terminal eMSC7002.

[0112] S702, the eMSC7002 performs signaling interaction with devices in the IMS (for example, the home server 7004 in the IMS) to update local information (for example, make the home server 7004 update the address of the eMSC7002 stored thereon, etc.).

[0113] S703, the eMSC7002 feeds back a local update success response to ...

Abstract

The invention discloses a call service implementation method and device, electronic equipment and a readable medium, and the method comprises the steps: judging whether a first state of a terminal in an enhanced mobile switching center is consistent with a second state of the terminal in a network protocol multimedia subsystem (IMS) or not, and if not, sending a registration request to the IMS, so that the terminal completes an initial call service, wherein the enhanced mobile switching center does not subscribe the registration state information in the IMS; judging whether the first state is consistent with the second state or not, and if the first state is inconsistent with the second state, sending a registration request to the IMS, so the terminal communicates with equipment in the network protocol multimedia subsystem and completes an initial call service, and obtaining related service information in the network protocol multimedia subsystem; therefore, the enhanced mobile switching center and the equipment in the IMS do not need to consume memory resources to subscribe and notify the registration state information, the CPU consumption of the enhanced mobile switching center and the equipment in the IMS is reduced, the network signaling flow is reduced, and the performance of the network element is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of communications, and in particular, to a method and device for implementing a call service, electronic equipment, and a readable medium. Background technique [0002] Internet Protocol (IP for short) Multimedia Subsystem (IP MultimediaSubsystem, IMS) is an IP-based network architecture proposed by The 3rd Generation Partnership Project (3GPP), which builds an open The flexible business environment supports multimedia applications and provides users with rich multimedia services. IMS has nothing to do with access technology, except for general packet radio service (General Packet Radio Service, GPRS), wireless local area network (Wireless Local Area Network, WLAN), packet switching (Packet Switched, PS) and evolved packet system (Evolved Packet System, EPS) and other access networks can also provide services for mobile cellular networks such as Global System for Mobile Communicat...
