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...

Abstract

The invention discloses a method, a device and a system for checking mobile station roaming number (MSRN), which belong to the field of communications and solve the problem of cross talk due to MSRN misidentification. The method for checking mobile station roaming number (MSRN) comprises the following steps: receiving a call request, wherein the call request carries a mobile station roaming number and a first check number; acquiring a pre-stored second check number according to the mobile station roaming number carried by the call request and a pre-stored relationship between the mobile station roaming number and the check number, wherein the second check number is carried by a roaming number distribution request, and the relationship between the mobile station roaming number and the check number is stored during the distribution of the mobile station roaming number; judging whether the first check number and the second check number are same; and if not, determining the mobile stationroaming number is wrong. The method, the device and the system can be applied to GSM networks, CDMA networks and WCDMA networks.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for checking the roaming number of the mobile station when the called mobile station is roaming. Background technique [0002] In order to realize the roaming function, GSM defines MSRN (Mobile Station Roaming Number, mobile station roaming number) for users. In the GSM (Global System for Mobile Communications, Chinese is the Global System for Mobile Communications) and WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) CS domain (Circuit Switch, circuit bearer domain) network, in the roaming state When the mobile station of the mobile station is the called party, the VMSC (Visited Mobile Switching Centre, Visited Mobile Switching Center) where the mobile station is currently located will allocate an MSRN for the mobile station, and notify the MSRN to the GMSC (Gateway Mobile Switching Center) where the calling terminal is ...
