Problems solved by technology
And for those networks with no or little compatibility between network protocols (such as CDMA network and GSM network), there is currently no dual-mode single-standby mobile terminal that can realize adaptive selection between these access networks; That is to say, the current dual-mode single-standby terminal cannot dynamically and adaptively select the access network according to the actual network conditions for those networks with no compatibility between network protocols, or networks with low compatibility.

Embodiment Construction
[0029] The dual-mode single-standby mobile terminal provided by the embodiment of the present invention can realize adaptive switching between wireless access networks with incompatible or less compatible network protocols, such as switching between a CDMA access network and a GSM access network, Or realize adaptive handover between the CDMA access network and the WiMAX access network. The following takes the dual-mode single-standby mobile terminal to realize the adaptive switching between the CDMA access network and the GSM access network as an example to describe the specific scheme. For the switching between other access networks, those skilled in the art disclose according to the embodiment of the present invention The technical content of can be easily realized, so I won't list them here one by one.
[0030] The dual-mode single-standby mobile terminal may have a selection handover strategy, that is, set a preferred network to be handed over to. For example, the handove...

The invention relates to the field of mobile communication, particularly relating to the technology for the dual-mode single waiting mobile terminal to be switched in the heterogeneous network. The invention provides a dual-mode single waiting mobile terminal and the switching method thereof in the heterogeneous network, including: when the mobile terminal stands by in the first network, search the second network periodically; if the second network is found, the mobile terminal breaks the connection with the first network and establishes the connection with the second network; the second network is the optimize standby network of the mobile terminal. While standing by in the first network, the mobile terminal searches the second network periodically and switches to the second network after finding the second network, so the mobile terminal can adapt to the selection and switching of the network automatically according to the actual network.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a technology for switching between heterogeneous access networks for a dual-mode single-standby mobile terminal. Background technique [0002] The future mobile communication network presents a development trend of broadband and the coexistence of various heterogeneous wireless access networks. In a heterogeneous network environment, it is common for multiple wireless access networks to cover the same area and provide services; on the other hand, with the reduction of network interface costs, dual-mode mobile terminals have become a development trend, and mobile terminals It has two heterogeneous wireless interfaces, such as GSM (Global System For Mobile Communication, global mobile communication) and CDMA (Code Division Multiplex Address, code division multiple access) wireless interface, TD-CDMA (Time Division Synchronous Code Division Multiple Access, time division synchron...
