Problems solved by technology

[0006] However, the mobile IP technology requires the home network of the user terminal to include a network element with the HA function, but the current communication network does not have this function
That is to say, using the above method to realize the service switching of user terminals between multi-standard networks requires major changes in the GSM / UTMS core network, such as: adding the HA function to the GPRS support node (SGSN) or GGSN. Therefore, this requires The redesign of network equipment in the existing core network will bring a lot of investment and time costs to mobile operators

Embodiment Construction

[0038] In order to realize the handover of the user terminal between networks, the embodiment of the present invention adopts setting a NIG between two access networks to store the corresponding relationship between the location parameter of the neighboring network and the ANC address of the neighboring network. When the ANC of the roaming network of the user terminal receives the mobile message of the user terminal, it sends the mobile message to the NIG, which at least includes the location parameter of the user terminal in the home network; The corresponding relationship between the location parameter and the ANC address of the adjacent network determines the ANC address of the home network corresponding to the location parameter of the user terminal in the home network; the NIG performs handover negotiation with the ANC of the roaming network and the ANC of the home network, A data transmission tunnel between the ANC of the roaming network and the ANC of the home network is...

Abstract

The disclosed business-switch method among different system networks comprises: the cruised ANC sends mobile message contained position parameter of the terminal home network from user terminal to NIG; the latter determines the ANC address of said home network according to the relation of the neighbor network position parameter and its ANC address; the NIG negotiates with the cruised ANC and homeANC to build a data transmission channel among them for home kernel network transmitting data with the user terminal. This invention implements smooth switch.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for service switching between multi-standard networks. Background technique [0002] With the development of wireless access technology, broadband wireless access technology (Bandwidth Wireless Access, BWA) realizes the high-speed wireless transmission of data between the terminal equipment in the local area network and the access network, and realizes the perfect solution of "the last mile coverage". . The Institute of Electrical and Electronics (IEEE) has defined a series of technologies applied to Wireless Local Area Network (WLAN), including 802.11, 802.16, and 802.20. The 802.11 protocol includes four substandards, namely 802.11, 802.11a, 802.11b, and 802.11g all use the Ethernet protocol (Ethernet protocol) and carrier frame sense multiple access / collision avoidance (Carrier Sense multiple access with collision avoidance, CSMA / CD)...
