Problems solved by technology

[0005] Although the 3GPP2 X.P0023 specification specifies in detail how CDMA network entities and GSM network entities transmit information (such as signaling and user data, etc.) How entities and GSM network entities are connected with the Interoperability Function (IIF)
In order to realize the connection scheme, huge funds must be invested to build this brand new network. At the same time, the existing CDMA network entities and GSM network entities must be modified accordingly to adapt to this network. Due to the large number of CDMA network entities and GSM network entities , so the corresponding modification workload is very large, so this connection scheme is not practical

Embodiment Construction

[0041] In the present invention, the network entities of each mobile communication network are connected with the interoperability functional unit (IIF) through their respective signaling networks, and the interoperability functional unit (IIF) is simultaneously used as the signaling transfer of each signaling network point (STP).

[0042] The following first combines the attached image 3 , taking the interconnection between a CDMA network and a GSM network as an example, describe in detail the scheme of connecting the network entities of the present invention with the interoperability functional unit (IIF) through respective signaling networks.

[0043] Such as image 3 As shown, the network entity 200 in the CDMA network is directly connected to a signaling transfer point 210 in the CDMA signaling network, wherein the signaling transfer point 210 may be a low-level signaling transfer point. The signaling transfer point 210 can be directly connected to the interoperability...

Abstract

This invention relates to an information transmission method and a device for realizing panning by users among multiple mobile communication networks which entities are interconnected by their own signaling networks and mutual operation function units (IIF), so each entity can be connected with IIF without any change to reduce the cost of network interconnection greatly.

Description

technical field [0001] The present invention relates to an information transmission method and device for realizing user roaming among multiple mobile communication networks by using a signaling network, in particular to a method and device for realizing user roaming between a CDMA network and a GSM network by using a CDMA signaling network and a GSM signaling network An information transmission method and device for inter-roaming. technical background [0002] Both GSM and CDMA are widely used second-generation mobile communication networks. Because they each use different communication standards, when a user who subscribes to GSM roams to an area covered by a CDMA network and wants to use the CDMA network to communicate, it is necessary to replace the terminal, user identification card and user number. The same goes for the area covered by the network. This causes great inconvenience to the user, because the user needs to be equipped with a terminal of different networks...
