A call processing method and device

Abstract

The invention provides a call processing method and a call processing device. The method comprises the following steps: receiving a call request from an IP multimedia system (IMS) domain, wherein the call request carries the number of a called user; sending an NAPTR (naming authority pointer) inquiring request to an affiliated regional ENUM (telephone number mapping) server; identifying a business signing type of the called user, and a domain type corresponding to the business signing type according to an inquiring result returned by the ENUM server; and judging whether the business signed by the called user is matched with the call request according to the business signing type of the called user and the domain type corresponding to the business signing type, if not, abnormal processing is carried out on the call request. With the adoption of the call processing method, the call failure rate under a mismatching condition and network resource wastes are reduced, and the flexibility and the accuracy of the processing on the call request by the call processing device are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a call processing method and equipment. Background technique [0002] With the application of IP Multimedia System (IMS for short) in the field of communication, in order to solve the shortage of operator number resources and meet the problem of users retaining common numbers, users use the same number in multiple core network domains, such as IMS network domain and Circuit System (CS) domain registration and login has become a trend. [0003] When an IMS voice user calls a RichcommunicationSuite (RCS) user, the above-mentioned RCS user is a user who subscribes to different services in the CS network domain and the IMS network domain with the same number. Other services such as instant messaging, file transfer, picture or video sharing services are provided by the IMS domain. The current call processing process in the IMS domain is as follows: [0004] The calli...

Problems solved by technology

[0008] In the above solution, the call service type corresponding to the call request is a voice service type, and the called user’s subscription service type includes the voice service type, but the network domain corresponding to the voice service type signed by the called user is a CS network domain, and the network domain corresponding to the call request initiated by the calling user is the IMS domain. Therefore, the call request cannot go out of the network after being routed to the IMS domain to which the called user belongs, resulting in call failure.
