Embodiment 1

[0037]An embodiment of the present invention provides a measurement method before inter-frequency handover of a user terminal, the method is a method on the serving base station side, such as figure 1 As shown, the method includes:

[0038] S101. The serving base station receives spectrum information from a non-serving base station, where the spectrum information includes the received power of the non-serving base station, and the received power of the non-serving base station is measured by the non-serving base station and received by the non-serving base station The strength of the signal sent by the user terminal.

[0039] The non-serving base station measures the strength of the signal sent by the user terminal received by the non-serving base station, which is the received power of the non-serving base station. Specifically, the non-serving base station can measure periodically, aperiodically, or based on Some trigger conditions are used for measurement, which is not lim...

Embodiment 2

[0060] The embodiment of the present invention provides a measurement method before the inter-frequency handover of the user terminal, such as image 3 As shown, when the serving base station is a macro base station, the method includes:

[0061] S301. The macro base station sends a caching instruction to the user terminal, so that the user terminal caches the transmission power at a corresponding moment in a corresponding resource block within a preset period of time after receiving the caching instruction.

[0062] Since the transmit power of the user terminal may be different at different times and on different resource blocks, when the user terminal enters the coverage area of ​​the macro base station, the macro base station will send a buffer instruction to the user terminal, which is used to instruct the user terminal to buffer The transmission power corresponding to the resource block and the corresponding moment in the predetermined period of time.

Embodiment 3

[0114] An embodiment of the present invention provides a serving base station 1, such as Figure 5 As shown, the serving base station 1 includes:

[0115] The receiver 10 is configured to receive spectrum information from a non-serving base station, where the spectrum information includes received power of the non-serving base station, and the received power of the non-serving base station is measured by the non-serving base station. The strength of the signal sent by the received user terminal;

[0116] An acquisition unit 11, configured to acquire user terminal transmit power;

[0117] A judging module 12, configured to judge whether the difference between the transmitting power of the user terminal and the receiving power of the non-serving base station is smaller than a preset threshold.

[0118] The transmitter 13 is configured to send a measurement instruction to the user terminal when the difference between the transmit power of the user terminal and the received powe...

Abstract

An embodiment of the invention provides a method and device for measuring different frequencies of a user terminal before switchover and relates to the communication field. The user terminal can be indicated to perform measurement of a non-service base station after the user terminal is judged to be close to the non-service base station, the measurement times of the user terminal are further decreased, and power consumption of the user terminal is reduced. The method for measuring the different frequencies of the user terminal before switchover comprises the steps of receiving frequency spectrum information from the non-service base station, wherein the frequency spectrum information includes receiving power of the non-service base station, and the receiving power of the non-service base station is measurement strength of the non-service base station to received signal sent by the user terminal; obtaining transmitting power of the user terminal; sending a measurement instruction to the user terminal to indicate the user terminal to measure the non-service base station when the difference between the transmitting power of the user terminal and the receiving power is smaller than a preset threshold value.

Description

technical field [0001] The present invention relates to the communication field, in particular to a measurement method and device before user terminal inter-frequency handover. Background technique [0002] In recent years, in order to adapt to the changes in the communication market and meet the needs of the growth of communication services, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) introduced the concept of sub-base stations and sub-cells to expand the coverage of cells and improve Cell system throughput and spectrum efficiency, this kind of communication network where macro base stations and micro base stations coexist is called a heterogeneous network. When a heterogeneous network is deployed, the frequency points of the micro base stations may be different from those of the macro base stations. Then, when the user terminal needs to switch between the macro base station and the micro base station, inter-frequency handover will ...
