Problems solved by technology

[0007] If the LTE system measurement event is used to configure LTE-NR dual connectivity measurement for the UE, that is, when the LTE primary base station configures NR service frequency point measurement for the UE, or the NR secondary base station configures LTE service frequency point measurement for the UE, selecting B1 and B2 events will Causes unnecessary measurement and measurement reporting, increases UE power consumption, and wastes valuable wireless signaling resources

Embodiment Construction

[0024] In 5G, it is assumed that several NR base stations are deployed in the coverage area of ​​the cell under the jurisdiction of the LTE base station. If the UE first accesses the LTE network, in order to configure the dual connectivity of LTE and NR, that is, to configure the NR base station as the SN, the LTE main base station needs to configure The UE measures the frequency point of the NR system, so that the UE can measure the NR frequency point cell, and find an optimal NR cell for the UE.

[0025] refer to figure 1 , gives a schematic diagram of a double connection in an embodiment of the present invention. In the specific process of configuring dual connectivity, the LTE primary base station (MN) can send a dual connectivity configuration request to the NR secondary base station (SN). After the NR base station configures wireless parameters for the UE, it returns a dual connectivity configuration response message to the LTE base station. The UE sends the wireless pa...

Abstract

The invention relates to a cell measurement configuration method and device. With the method adopted, after a user terminal builds inter-RAT connections, a first base station configures the measurement service frequency point of a radio access network corresponding to a second base station for the user terminal. According o the method, the measurement configuration information is set for the userterminal, wherein the measurement configuration information indicates that the user terminal limits the measurement and measurement reporting of a serving cell in an inter-RAT service frequency point;and the first base station and the second base station are in a primary-auxiliary relationship and are corresponding to different radio access networks. With the above technical schemes of the invention adopted, the power consumption of the UE during the construction of the inter-RAT connections can be decreased, and wireless signaling resources can be saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell measurement configuration method and device. Background technique [0002] Long Term Evolution (LTE) Release 12 introduces dual connectivity technology, so that user equipment (UE) can simultaneously use the resources of two LTE base stations for data transmission, which not only improves data throughput, but also enables Improve mobile performance. [0003] For a UE configured with dual connectivity, the connected primary base station (Master eNB, MN) is responsible for the transmission of radio resource control (Radio Resource Control, RRC) signaling, and the secondary base station (Secondary eNB, SN) is responsible for the secondary serving cell (Secondary Cell) , SCell) configuration and management. The SN only transmits data, and the secondary serving cell group configured by the SN needs to be sent to the UE through RRC signaling through the MN. Bot...
