Problems solved by technology

If the internal simultaneous grabbing is not handled, both calls will fail, and the call loss will be serious when the traffic volume is large.

Embodiment Construction

[0020] The solution to the external grab:

[0021] Please refer to the attachment for the occurrence of external robbery figure 2 . External synchronization is detected by the SS7UP module. After the SS7UP module receives the SetupInd of the BCM and sends out the IAM, it immediately receives the IAM message on the same circuit, so it can be concluded that the same robbery has occurred. For the solution of external co-robbing, see image 3 . After detecting the same robbery, SS7UP judges whether the local office is the master control office, and if so, discards the received IAM message. Otherwise, cache the received IAM message, and send a release call message (ReleaseInd) to the BCM module, and indicate that the reason for release is the same grab. After BCM receives the release event, it will reroute the previous call and send SetupInd on another circuit. After receiving the release response from BCM, SS7UP processes the cached IAM again and sends a new SetupInd to BCM...

Abstract

The resolution method under framework with separated signaling and business comprises: when SS7UP receives another IAM while sending IAM and waiting for BCM response, drops if master control or buffers if not, and indicates BCM to generate outside contend together; after reselecting path, SS7UP processes buffered IAM; when receives SetupInd before BCM sends SetupInd or after sending SetupInd, drops if master control, or reselects for calling if not main control and BCM has sent SetupInd, or records it as having content together, and checks the record after process to reselect for calling if having content. This invention can reduce calling loss when there is much telephone communication.

Description

technical field [0001] The present invention relates to communication field, specifically, relate to the TUP / ISUP (telephone user interface) of 13 interfaces (the interface between MSCe (mobile switching center emulation) and PSTN (public switched telephone network) fixed network) in the CDMA2000 system defined by 3GPP2 organization. part / ISDN user agreement) are processed at the same time. Background technique [0002] Signaling and service separation architecture: In the 3Gp2 protocol, MSCe has multiple signaling accesses, such as TUP, ISUP, SIP, A port, etc. Since their service processing has many similarities, a unified service can The processing module handles multiple signaling access services, that is, separates signaling processing into multiple signaling and unified services. In this paper, the business processing module is referred to as BCM (Basic Call Module). The structure is attached figure 1 . [0003] TUP / ISUP protocol: Proposed by ITUT organization, as t...
