Embodiment Construction
[0032]The embodiment of the present invention proposes a method for reselecting a cell in a wireless access system. This method can ensure that an idle terminal selects an appropriate RAT cell for camping. Through reasonable camping reselection, the service access time is shortened. The access time is improved, the service access efficiency is improved, the service communication quality is guaranteed, the potential switching in the service process is reduced, the air interface resources are further saved, the system capacity is improved, the user's needs are better met, and the Coordination of heterogeneous wireless networks.
[0033] see figure 2 , a method for reselecting a cell in a wireless access system proposed by an embodiment of the present invention, specifically includes the following steps:
[0034] Step 101: The RAT cell where the terminal is currently camping on collects relevant information of neighboring RATs.
[0035] The RAT cell where the terminal is curre...

The invention discloses a cell reselection method for a wireless access system, and a device, a terminal and a wireless access system thereof, and pertains to the field of wireless communication. In order to solve the problem of resident cell reselection of the terminal in the wireless access system, the invention provides the method for the cell reselection in the wireless access system that a current resident RAT cell at the terminal collects relevant information of adjacent RATs and the collected relevant information of the adjacent RAT is coded and combined to be a combination value of RAT information parameters to be broadcast to the terminal by an air interface; the received combination value of the RAT information parameters is decoded by the idle terminal and then the cell in the RAT which meets the resident conditions is selected to be processed by reselection measurement, and RAT resident cell is reselected according to the measurement result,. The invention also provides a device for reselecting the cell in the wireless access system and a wireless access system thereof. The invention guarantees the access performance and the communication quality of a subsequent service and improves the performance of the system.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a technique for reselecting cells in a wireless access system. Background technique [0002] With the development of high technology marked by communication technology and computer technology, people's lives have undergone tremendous changes with each passing day, and the information transmission between people is getting closer and more diverse. In the development process of cellular mobile communication, FDMA (Frequency Division Multiple Access-Frequency Division Multiple Access), TDMA (Time Division Multiple Access-Time Division Multiple Access) and CDMA (Code Division Multiple Access) have been experienced in terms of multiplexing methods. MultipleAccess-code division multiple access) three generations. The future wireless communication network will also be a situation where multiple wireless access systems coexist, such as GSM (Global System for Mobile communication-Gl...
