Method and system for realizing international nomadism call

Abstract

The invention discloses a method for realizing an international roaming call, comprising: a mobile terminal performs international roaming, and when the mobile terminal initiates a call, the MSC of the visiting country obtains the international roaming service access identifier of the mobile terminal, and according to the international roaming service The access identifier routes the call to the home country network of the mobile terminal; the invention also discloses a system for realizing international roaming calls, including: the mobile terminal, the MSC of the visiting country and the home country network; the invention also discloses a MSC for international roaming calls. The invention realizes the successful call when the mobile terminal roams to the visited country when the MSC of the visited country has WIN capability; and, since the call is routed to the home network of the mobile terminal for connection, the call control of the home network to the mobile terminal is realized , to avoid the loss of the operator; at the same time, by configuring different international roaming service access identifiers for different operators or SCPs, different charging strategies are realized.

Description

technical field [0001] The invention relates to the technical field of mobile intelligent network, in particular to a method and system for realizing international roaming calls during international roaming, and a mobile switching center. Background technique [0002] As the degree of internationalization becomes higher and higher, mobile terminals often need to roam from one country to another, which requires operators to provide borderless communication services. [0003] At present, when a mobile terminal roams from a home country to a visiting country and initiates a call, if the mobile switching center / service switching point (MSC / SSP) of the visiting country does not have the wireless intelligent network (WIN) capability, the MSC / SSP of the visiting country The SSP does not perform signaling interaction with the service control point (SCP) of the home country at all, but directly connects the call, that is, the mobile terminal can initiate any call in the visiting coun...

Problems solved by technology

At this time, since the SCP in the home country cannot control the call, it may cause losses to the operator in the home country. For example, the operator cannot charge the call in real time. bring economic losses to operators

[0004] After the mobile terminal roams from the home country to the visited country, if the MSC / SSP of the visited country has WIN capability, when the mobile terminal registers its location with the Home Location Register (HLR), the HLR can trigger the trigger of the mobile terminal However, because the operators of the two countries usually lack the cooperation of the signaling addressing address on the WIN side, the MSC / SSP in the visiting country cannot perform authentication and other signaling with the SCP in the home country interaction, causing the mobile terminal to be unable to initiate a call at all
