Embodiment Construction

[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the method for controlling the switching execution time of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] refer to figure 1 , figure 1 The implementation process of the first embodiment of the method of the present invention is shown, including the following steps:

[0042] Step 101: the user equipment obtains the information of the neighboring cells issued by the network side.

[0043] The user equipment may obtain the information of the neighboring cells through a system message or a dedicated measurement control message delivered by the network side. For example, when cell selection or reselection is required, the network side sends a system message to the user equipment, which contains the information of neighboring cells, and the user equipment needs to measure the current ...

Abstract

The invention discloses a method for maintaining the information of an adjacent cell in a long-term evolution system. Aiming at the characteristic that the LTE system supports the variable bandwidth technology, the user equipment determines the measurement types which can be applied to various cells according to the measurement types indicated by a network side and the information of the adjacent cell sent down after receiving the information of the adjacent cell so as to save the effective information of the adjacent cell into a corresponding same frequency adjacent cell list or different frequency adjacent cell list or first saves all the information in the adjacent cell list, determines the measurement types which can be applied to various cells when the measurement needs to be carried out and then determines the adjacent cell to which the corresponding measurement can be applied from the adjacent cell list after receiving the information of the adjacent cell. The invention also discloses a terminal, which can effectively maintain the information of the adjacent cell under an LTE frame. By the utilization of the invention, the effective information can be provided to the user equipment for the measurement of the adjacent cell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and a terminal for maintaining information of neighboring cells in a long term evolution system. Background technique [0002] In order to make the wireless access technology of 3GPP (The 3rd Generation Partnership Project, third-generation mobile communication standardization partner project) in a favorable position in the environment of fierce competition in future mobile communication technology, it is necessary to consider the long-term evolution of the 3GPP wireless access technology ( LTE, Long Term Evolution). In LTE, the main problems to be solved are: obtaining higher user data rate, improving system capacity and coverage, and reasonable and flexible spectrum allocation. [0003] A UE (User Equipment) needs to perform neighbor cell measurement before performing processes such as cell handover and cell reselection, so as to select a suitable neigh...
