Problems solved by technology

The inventors of the present application found that in this case, there are at least the following problems: Does the UE need to measure all types of neighboring cells or select certain types of neighboring cells or certain neighboring cells for measurement? If all types of neighbors or all neighbors are measured, it may cause unnecessary waste of system resources
If certain types of neighborhoods or certain neighborhoods are selected for measurement, how are they selected or determined, and how are the selected neighborhoods measured? Currently there is no related solution in LTE

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] The first embodiment of the present invention provides a neighbor cell selection method in LTE.

[0034] In the technical solution provided in this embodiment, after the type of the adjacent cell is known, the adjacent cell is selected with reference to the type of the adjacent cell. The specific selection method can be divided into cases where priority is considered and cases where priority is not considered.

[0035] 1. Consider the priority:

[0036] 1) According to the matching relationship between the neighbor cell type and the UE's current service, preferentially select a neighbor cell that completely matches the UE's current service, and the completely matched neighbor cell refers to a neighbor cell that only supports the UE's cur...

Abstract

The invention relates to the wireless communication field and provides a method for measuring an adjacent cell by using an LTE system, which comprises the following steps: the adjacent cell to be measured is activated and started, and UE searches for the adjacent cell and measures the searched-out adjacent cell according to the rule of adjacent cell measurement. The invention further provides a method for selecting the adjacent cell in the LTE system. By the method, the UE selects the cell adjacent to the cell where the UE is located. The method for measuring the adjacent cell in the LTE system and the method for selecting the adjacent cell solve the technical problem that no related methods for measuring and selecting the adjacent cell exist in the prior LTE system, thus reducing the waste of system resources.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the technology of neighbor cell measurement and neighbor cell selection 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 ( Long Term Evolution, LTE). 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] In LTE, cell types include: unicast (unicast) cells, multimedia broadcast / multicast service (Multimedia Broadcast / Multicast Service, MBMS) dedicated (dedicated) cells, and mixed (m...
