Problems solved by technology

[0013] It can be seen from this that when the signals of LTE, UMB, and WiMAX cells are better than those of TD-SCDMA, WCDMA, cdma20001x, and HRPD cells in the same area, dual-mode or multi-mode Terminals cannot quickly and smoothly reside in and switch to LTE, UMB, and WiMAX cells, and can only access LTE, UMB, and WiMAX networks by disconnecting from the network and re-selecting networks, which seriously affects service use and user experience

Embodiment Construction

[0037] Specific embodiments of the present invention will be further described in detail below. The above and other objects, features and advantages of the present invention will be apparent to those skilled in the art from the detailed description of the present invention.

[0038] The core idea of ​​the present invention is to increase the adjacent cell information of LTE, UMB and WiMAX technology in the relevant agreement of the third generation mobile communication system WCDMA, TD-SCDMA, cdma20001x, HRPD, realizes that the dual-mode terminal can operate in WCDMA, TD-SCDMA and Measurement of LTE, UMB or WiMAX neighbor cells in cdma20001x, HRPD networks. Considering the evolution and further enhancement of mobile communication networks, in the next few years, there will be existing protocols supporting WCDMA and / or TD-SCDMA and / or cdma20001x, HRPD and LTE and / or UMB and / or WiMAX in the market. Multi-mode / dual-mode terminals for new protocols. In the scenario where an oper...

Abstract

The invention discloses a method for supporting cross system residence and switch of a multimode system, comprising: when the network side system supports the WCDMA protocol and/or the TD-SCDMA protocol and or/ the cdma2000 1x protocol and/or the HRPD protocol, the network side adds the adjacent cells information and the measuring task of LTE and/or UMB and/or WiMAX in the protocol to make the terminals capable of measuring the adjacent cells of LTE and/or UMB and/or WiMAX protocol in the network of WCDMA and/or TD-SCDMA and/or cdma2000 1x protocol or HRPD protocol and reporting the measuring result to a superior system. The invention makes the prior network capable of sending adjacent cells information of LTE and/or UMB and/or WiMAX, thus not only the continuous overlay can be realized with the help of the existing network when the network of a new protocol has insufficient overlay and weak signal intensity at the initial setup stage, but also a new network is selected preferably when the network service of a new protocol with stronger wireless capability is 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] Currently, in the standard of the third generation mobile communication system, the neighbor cell information that the terminal needs to obtain is delivered from the network side. For WCDMA and TD-SCDMA networks, after the terminal completes the cell residency, it uses the neighbor cell information indicated in the received system information block (SIB11, SIB12) to measure the neighbor cell, and completes the cell selection according to the strategy set by the network . For a terminal in the connected state, it can also measure neighboring cells according to the neighboring cell information in the received measurement control message (MEASUREMENT CONTROL), so as to provide reference information for switching to neighboring cells. [0003] Neighboring cells of WCDMA and TD-SCDMA are divided into three types: Intra-f...
