Abstract

The embodiment of the invention provides a call processing method and system, and a storage medium. The method comprises the following steps: acquiring a roaming number corresponding to a telephone number of a called party from an HSS (Home Subscriber Server) by an IMS network by acquiring a call request initiated by a calling party based on the call request; acquiring routing information corresponding to the roaming number from a number portability mobile switching center; and routing the call request to a second operator network based on the routing information, so that the second operator network can connect the call request to the called party. According to the call processing method provided by the invention, the problem that a number portability user communicates with the calling party in the IMS network as the called party after rolling out to other networks is solved, so that the user can also communicate with the calling party in the IMS network after the user carry the numberto roll out to other networks, so that the normal call of the number portability user is ensured.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular, to a call processing method, system, and storage medium. Background technique [0002] figure 1 It is a solution architecture diagram provided by the prior art in which the number portability user acts as the called user during a circuit domain (CS) voice call, as shown in figure 1 As shown, when a user of the first mobile operator acts as a calling user to call a number portability user, the visiting mobile switching center (VMSC) of the first operator initiates a request for routing information to the home location register (HLR) of the called number (SRI) request, the old HLR sends a request to provide a roaming number (PRN) to the Number Portable Mobile Switching Center (NPMSC), and the NPMSC returns a pseudo roaming number (MSRN) to the old HLR, where the MSRN includes the wireless network (RN) Information and mobile subscriber ISDN num...
