Example Embodiment

[0069] In order to connect a service request arriving from another domain to the user when the user terminal is registered in a certain domain, so as to realize cross-domain reception of services.

[0070] ● The present invention provides a VCC AS entity, which has call anchoring and domain switching functions, as shown in Figure 4, it also includes: an association module, and a judgment module and a notification module connected to each other; further, it also includes: call hold Module.

[0071] The judging module is used to judge whether the user terminal pointed to by the service request arriving from one domain is currently registered in another domain, and if so, it sends a trigger signal. The further judgment module can also detect whether the user terminal is currently performing services in another domain after receiving the service request; when it is detected that the user terminal is currently performing services in another domain, it determines whether or not accordin...

Abstract

The invention discloses cross-domain service receiving method, device and system. The method includes the following steps: informing the user terminal while the VCC AS is receiving the service request pointed to another domain user terminal; covering into the service request original domain if the user terminal satisfies the given condition; connecting the service by associating the service and the user terminal in the original domain. The invention can solves the problems that the user has no network option; current original dialog can not be treated while new service is arriving at the user terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for receiving services across domains. Background technique [0002] During the evolution of the wireless network from the 2G network to the 3G network, the 3G network and the 2G network will coexist for a long period of time. topic. [0003] In order to solve the above problems, the 3GPP2 standard organization proposes a VCC (Voice Call Continuity) architecture, and the schematic diagram of the architecture is shown in FIG. 1 . [0004] In this architecture, two new network elements are added, one is the voice call continuity application server VCCAS, and the other is the short message gateway SMS-GW. The SMS-GW is used for intercommunication of short messages, which has nothing to do with the present invention. The VCC AS is a network entity in the IMS domain, but has interfaces with some network elements in the CS domain. It is used to assist i...
