Problems solved by technology

In the existing interval measurement mode, if the UE initiates measurement with a large number of frequency points of different frequencies or different systems, it will not only affect the eNB’s function control of the UE and the data interaction between the eNB and the UE, but also because the UE receiver is in different frequency points. Due to frequent switching between frequency points and different system frequency points, the battery consumption of the UE is relatively high

Embodiment Construction

[0026] In the control method and system for implementing inter-frequency and inter-system measurement based on the LTE architecture of the present invention, the eNB flexibly controls the UE to perform inter-frequency measurement and / or inter-system measurement according to the measurement enable event triggered by the UE based on the measurement enable configuration information, the following is combined with the accompanying drawings Specific embodiments of the present invention will be described.

[0027] First of all, the standard protocol for inter-frequency and inter-system measurement in the existing LTE system generally includes the following events:

[0028] A2 event: measurement start event. That is, when the eNB receives the same-frequency measurement A2 event reported by the UE, it sends an inter-frequency measurement enable command or an inter-system measurement enable command to the UE, and can also issue an inter-frequency measurement enable command and an inter...

Abstract

The invention discloses a long-term evolution (LTE) architecture-based control method and an LTE architecture-based control system for implementing inter-frequency and inter-system measurement. The method comprises the following steps that: eNB transmits measurement starting configuration information to user equipment (UE); and the eNB receives a measurement starting event triggered by the UE on the basis of the measurement starting configuration information and transmits an inter-frequency measurement starting command and / or an inter-system measurement starting command and corresponding measurement stopping configuration information to the UE. Through the provided technical scheme, the UE flexibly controls the inner-frequency measurement and / or inter-system measurement, the functional control of the UE by the eNB and the data interaction between the eNB and the UE are guaranteed, and the battery overhead of the UE is effectively reduced.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a control method and system for realizing inter-frequency and inter-system measurement based on LTE architecture. Background technique [0002] LTE (Long Term Evolution: Long Term Evolution) system refers to the evolution project proposed by 3GPP (Three Generation Partnership Project: Third Generation Partnership Project) for the third generation (3G) mobile communication technology, which is mainly used to improve the performance of cell edge users. Improve cell capacity and reduce system delay, etc. [0003] In the actual application of the LTE system, when the UE (User Equipment: user equipment) enters a different-frequency neighbor cell or a different-system neighbor cell from the current serving cell, the UE needs to measure the communication quality of the neighbor cell, and judge whether it is necessary to perform Inter-frequency handover or inter-system handover...
