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

Embodiment Construction

[0069] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0070] Fig. 1 is the flow chart that the present invention provides when the mobile terminal calls when international roaming, as shown in Fig. 1, its specific steps are as follows:

[0071] Step 101: A mobile station (MS) roams from a home country to a visited country, and initiates a location registration request message to the HLR through the MSC of the visited country.

[0072] The MS initiates the location registration request message of the MSC in the visiting country to carry the routing information of the HLR.

[0073] Step 102: After receiving the location registration request message, the HLR sends the information about the MS supporting international roaming service and the MS's international roaming service access ID to the MSC in the visiting country through the location registration response message, and the MSC in the v...

Abstract

This invention discloses one method to realize international roaming calls, which comprises the following steps: mobile terminal processes international roaming and visited nation MSC gets the roaming label when starting calls according to international roaming business interface label through mobile terminal. The invention discloses one system to realize international calls, which comprises mobile terminal, visit nation MSC and belonged nation network. The invention discloses one position method, HLR and MSC.

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, a location registration method, a home location register 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 m...
