Problems solved by technology

However, due to the low transmission power of low-power nodes, their cell coverage is much smaller than that of traditional macro cells. Therefore, how to effectively and timely detect small cells near the user equipment (User Equipment, UE) and migrate to a small cell with sufficient signal quality in time Well, it allows the UE to reside on a small cell without consuming too much UE power, which is directly related to the increase in system gain brought about by the deployment of low-power nodes
To sum up, there is currently no relevant solution to achieve effective and timely detection of small cells

Embodiment 1

[0130] Such as Figure 9 As shown in the schematic diagram of network coverage, the UE has established an RRC connection in the macro cell, and within the coverage of the macro cell, two small cells with the same frequency as the macro cell are deployed, namely small cell 1 and small cell 2. The base station to which the macro cell belongs can obtain the location information of each small cell within its coverage area through OAM (Operation Administration and Maintenance), or through the interface between the macro base station and the LPN where the small cell is located. In this embodiment, the value of the measurement parameter S-measure configured by the current macro base station for the UE is S-measure1.

[0131] In order to detect in time the Figure 9 For the small cells shown, in this embodiment, the macro base station uses the location information of each small cell to configure a small cell detection event for the UE, that is, the macro base station can know the loc...

Embodiment 2

[0155] Such as Figure 10 As shown in the schematic diagram of network coverage, the UE has established an RRC connection in the macro cell (working frequency f1), and within the coverage of the macro cell, two small cells with different frequencies from the macro cell (working frequency f1) are deployed. is f2), which are small cell 3 and small cell 4 respectively. The base station to which the macro cell belongs can obtain the location information of each small cell within its coverage area through the OAM or through the interface between the macro base station and the LPN where the small cell is located. In this embodiment, the value of the measurement parameter S-measure configured by the current macro base station for the UE is S-measure1.

[0156] In order to detect in time the Figure 10 For the small cells shown, in this embodiment, the macro base station configures a small cell detection event for the UE by using the location of each small cell.

Embodiment 3

[0181] In this embodiment, when the operator allocates frequency resources, some frequency resources are specially reserved for the deployment of LPNs. On these specially reserved frequency resources, only LPNs are deployed, and macro base stations are not deployed. These frequency resources are referred to herein as LPN dedicated frequency resources, that is, all small cells work on dedicated frequency resources.

[0182] The UE has established an RRC connection in the macro cell. In order to detect the small cell in time, in this embodiment, the macro base station configures the measurement parameters on the LPN dedicated frequency for the UE. Specifically, once the UE establishes an RRC connection in the macro base station, the macro base station can provide The UE configures the measurement parameters on the LPN dedicated frequency;

[0183] The measurement of the dedicated frequency by the UE is not restricted by the S-measure, that is, when the UE measures the neighborin...

Abstract

The invention discloses a measurement processing method and a system. The method comprises the following steps of: receiving an adjacent cell detection event configured by a network via user equipment (UE); measuring a service cell by the UE, and submitting a measurement report to the network by the UE when signal quality of the service cell meets a triggering condition of the adjacent cell detection event; and receiving an adjacent measurement starting threshold (S-measure) configured by the network via the UE, and / or, receiving a notification sent by the network for a measurement corresponding to starting or stopping of the adjacent detection event via the UE. By adopting the technical solution of the invention, a small cell can be detected in time without increasing a large amount of power consumption of the UE, therefore, the deployment of lower power nodes (LPN) can be ensured to enhance cell coverage effectively, network capacity can be increased, and macro cell loads can be shared.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a measurement processing method and system. Background technique [0002] With the development of mobile communication and information technology, users' demand for data services is increasing day by day. The current mainstream mobile communication network, whether it is the 2nd generation / 2.5th generation mobile communication network using GSM (Global System For Mobile Communication, Global System for Mobile Communications) / GPRS (General Packet Radio Service, General Packet Radio Service), or using The third-generation mobile communication network of UMTS (Universal Mobile Telecommunications System) is a homogeneous network (Homogeneous Network) planned and deployed by operators. Once a homogeneous network is deployed, the capacity of the network in a certain area is fixed. . [0003] In order to meet the ever-increasing demand for data services, operators...
