Problems solved by technology

[0003] At present, the multi-carrier standard work of LTE is very mature, but with the increase of the number of users, more carriers need to be provided for UE to support its data transmission. For example, LTE currently supports up to 5 carriers serving UE at the same time, which means The UE needs to perform radio resource management (Radio Resource Management, RRM for short) measurement for all five carriers, resulting in a significant increase in the workload of RRM measurement
In addition, small cells (small cells) are introduced in LTE R12. The coverage radius of small cells is very small and the density is relatively high. This will cause UEs to switch between small cells frequently, which will inevitably cause a lot of RRM to UEs. measurement requirements
[0004] Aiming at the problem in the related art that the UE frequently switches between small cells and causes the UE's RRM measurement workload to increase, no effective solution has been proposed so far

Embodiment 1

[0141] When UE1 is configured with 3 carriers on the network side, UE1 needs to perform corresponding RRM measurement for each carrier. Obviously, the RRM measurement workload of UE1 is relatively large at this time. According to the present invention, it can be improved in the following manner.

[0142] The network side receives and counts the RRM measurement results of UE1 for each carrier, and determines the corresponding relationship between the RRM measurement results of the three carriers. If the RRM measurement results of two or three of the three carriers are the same, or approximate are the same (the error is smaller than the set threshold), then the network side configures the carrier with the same or approximately the same RRM measurement result as a quasi-substitute carrier for the RRM measurement, and forms the corresponding information (signaling) to send to UE1. It may be assumed that these 3 The RRM measurement results of the two carriers are approximately the ...

Embodiment 2

[0144] When UE1 is configured with 3 carriers on the network side, UE1 needs to perform corresponding RRM measurement for each carrier. Obviously, the RRM measurement workload of UE1 is relatively large at this time. According to the present invention, it can be improved in the following manner.

[0145] The network side receives and counts the RRM measurement results of UE1 for each carrier, and determines the corresponding relationship between the RRM measurement results of the three carriers. If there are three carriers, the RRM measurement results of the cc2 and cc3 carriers are the same, or approximately are the same (the error is less than the set threshold), then the network side configures the carrier with the same or approximately the same RRM measurement result as a quasi-substitute carrier for RRM measurement, and forms the corresponding information (signaling) to send to UE1. It may be assumed that cc2 and The RRM measurement results of cc3 carriers are approximate...

Embodiment 3

[0147] When UE1 is configured with 3 carriers on the network side, UE1 needs to perform corresponding RRM measurement for each carrier. Obviously, the RRM measurement workload of UE1 is relatively large at this time. According to the present invention, it can be improved in the following manner.

[0148] The network side receives and counts the RRM measurement results of UE1 for each carrier, and determines the corresponding relationship between the RRM measurement results of the three carriers. If there are three carriers, among which the RRM measurement results of the cc2 and cc3 carriers satisfy a certain relationship, And this relationship remains unchanged (or the change is very small, less than the set threshold), such as a fixed compensation factor, then the network side can configure cc2 and cc3 to meet the RRM measurement quasi-substitution relationship, and send the configuration information to UE1 . For example, the network side configures cc3 as the target carrier...

Abstract

Disclosed are a radio resource management (RRM) measurement method and system, the method comprising: a base station configures for a user equipment (UE) the quasi substitution information of an RRM measurement, the quasi substitution information being used to indicate that the RRM measurement result of a first carrier can substitute for the RRM measurement result of a second carrier, and the first carrier being different from the second carrier; and the base station transmits the quasi substitution information to the UE. The present invention reduces the times of RRM measurement executed by a UE, reduces the times of different-frequency measurement during handoff executed by the UE, and reduces UE energy consumption.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for radio resource management measurement. Background technique [0002] With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service (QoS) of mobile communication. , referred to as 3G) before large-scale commercial use, the research and development of the next-generation mobile communication system has already begun, and the typical one is the launch of the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP). The Long Term Evolution (LTE for short) project of the Long Term Evolution (LTE for short) project, the highest spectrum bandwidth that the LTE system can provide is 20MHz (megahertz). With the further evolution of the network, evolved LTE (LTE-A), as an evolved system of LTE, can pro...
