Embodiment Construction
[0035] In the prior art, when the mobile station in the roaming state is the called party, the VMSC where the mobile station is currently located will allocate an MSRN for the mobile station, and notify the MSRN to the GMSC where the calling terminal is located, and the calling terminal The GMSC where it is located records the MSRN, and initiates an incoming call to the VMSC where the called party is located according to the MSRN, and then the VMSC finds the corresponding user according to the MSRN and issues a call.
[0036] Since the called mobile station only has the identification of MSRN, when the calling GMSC reads the recorded MSRN, it is easy to generate a wrong MSRN; or the time interval between the calling GMSC receiving the MSRN and sending the call request exceeds the timer Time limit, when the MSRN has been released and entered the idle state, the VMSC may have assigned the MSRN to another call. At this time, the MSRN sent by the calling GMSC has just become wrong...
