Method supporting cross-system residence and switching by multi-mode terminal

Abstract

The invention provides a method that supports cross-system residency and switch of a multimode terminal. The method comprises the following steps: when a network side system supports a WiMAX protocol, the adjacent cell information and measurement requirements of GSM and / or TD-SCDMA and / or WCDMA and / or cdma2000 1x and / or HRPD and / or LTE and / or UMB are added to the protocol by the network side, so that the terminal can measure the adjacent cells of other protocol networks in the WiMAX protocol network. The method improves the WiMAX network, and enables the WiMAX network to send the adjacent cell information of other protocols. Therefore, when a blind area exists in the signal coverage area of the WiMAX network and the signal intensity is low at the beginning of network setting, the WiMAX network can not only realize continuous coverage through other networks, but also preferentially select the WiMAX network when new protocol network services of higher wireless capability are available.

Description

technical field [0001] The invention relates to a method for supporting multi-mode terminals to reside and switch across systems. Background technique [0002] WiMAX (Worldwide Interoperability for Microwave Access), also known as 802.16, is an emerging broadband wireless access technology that can provide high-speed Internet-oriented connections, and the data transmission distance can reach up to 50km. In order to improve spectrum resource utilization and adapt to various broadband multimedia applications, WiMAX adopts a large number of new technologies (such as OFDM / OFDMA, MIMO, adaptive coding and modulation, etc.). WiMAX is also a technical system for future public wireless broadband data networks proposed by the Internet camp. It represents the broadband and intelligent features of future wireless communication systems. It has the advantages of QoS guarantee, high transmission rate, and rich and diverse services. [0003] For the WiMAX network, after the terminal succe...

Problems solved by technology

Usually in the initial stage of network construction, the network coverage is not perfect and there are many loopholes. In particular, it is necessary to provide users with seamless and continuous network coverage with the help of existing commercial mobile networks that have been widely covered. At the same time, it is necessary to support multiple wireless access technologies. Die terminals work together to meet the needs of such
