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.
