Embodiment Construction

[0097] When the ICS architecture in the prior art is used to implement the voice communication of a single-standby LTE terminal registered on the LTE network as the called end, call routing needs to perform multiple detours between multiple devices in the ICS architecture, which will cause service delays It is relatively long, and the called end needs to sign the ICS service. At the same time, the MSC in the ICS architecture also needs to support the ICS service, which also requires the transformation of a large number of MSCs, wasting resources. Therefore, the embodiment of the present invention proposes a method of introducing ECG in the existing network, connecting the ECG between the circuit domain of the 2G / 3G network and the IMS domain of the LTE network, and through the interaction between the HLR and the ECG, and the interaction between the MSC and the The ECG interaction realizes the call initiated by the calling terminal registered on the 2G / 3G network to the call reg...

Abstract

The invention discloses a service processing system, a service processing method and a service processing device, and aims to solve the problem that the prior art is long in service time delay. SRI (send routing information) is sent to an HLR (home location register) of a called terminal by an MSC (mobile switching center) of a calling terminal of the service processing system, when address information of an ECG (enhanced convergent gateway) of the called terminal is found out by the HLR of the called terminal, PRI (provide roaming identity) information is sent to the EGC which distributes the first MSRN (mobile station roaming number) for the called terminal, the distributed first MSRN is returned to the MSC of the calling terminal, An IAM (initial address message) carrying the first MSRN is sent to the ECG by the calling terminal, the ECG searches a CSCF (call session control function) module of the called terminal according to the first MSRN, and the called terminal is called via the searched CSCF module. In the service processing system, the service processing method and the service processing device in the embodiment, the calling terminal registered in a 2G / 3G (2nd generation / 3rd generation) network can call the called terminal registered in an LTE (long term evolution) network via interaction between the HLR of the called terminal and the ECG of the called terminal and interaction between the MSC of the calling terminal and the ECG, calling routing detouring is reduced, and service delay is shortened.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a system, method and device for service processing. Background technique [0002] In the existing second generation mobile communication (2nd Generation, 2G) / third generation mobile communication (3rd Generation, 3G) network architecture, the CS domain provides voice services for mobile users. Specifically, when the calling terminal initiates a call to the called terminal, it first sends the number of the called terminal to the mobile switching center (Mobile Switching Center, MSC) corresponding to the calling terminal, and the MSC corresponding to the calling terminal sends the number to the called terminal according to the number of the called terminal. The corresponding home location register (Home Location Register, HLR) of the called terminal sends and sends routing information (Send Routing Information, SRI), and queries the location information of th...
