Embodiment 1

[0056] In the WCDMA system, the schematic diagram of its network layout can be found in figure 1 , there is an Iub interface between the radio network controller RNC and the base station to which it belongs, and the UE is located in the cell to which base station 1 belongs. At this time, the UE is in the connected state, and the UE has a list of CSG cells that are allowed to be accessed. The specific process of the UE's measurement is as follows:

[0057] The RNC sends a measurement control message to the UE, wherein the measurement control message includes a measurement identifier (the measurement identifier corresponds to a measurement object and a measurement event 3c of a different system), information of neighboring cells to be measured, TTT, etc., and the reporting form is an event Trigger a single report. The measurement event 3c refers to that the signal quality of the neighboring cell located in the different system exceeds a predetermined threshold.

[0058]The UE ...

Embodiment 2

[0062] In the LTE system, the schematic diagram of its network layout can be found in figure 2 , there is an S1 interface between the core network and the base station (macro base station), and there is an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or can be connected to the core network through the home base station gateway. There is no X2 interface between the home base station and the macro base station. The UE is located in the cell to which the macro base station belongs and is in a connected state. The UE has a list of CSG cells that are allowed to access.

[0063] The macro base station sends a measurement control message to the UE, wherein the measurement control message includes measurement identifier 1 and measurement identifier 2 (measurement identifier 1 corresponds to frequency f1 and measurement event A3, measurement identifier 2 corresponds to frequency f2 and measurement event A3), needs to...

Embodiment 3

[0069] In the LTE system, the schematic diagram of its network layout can be found in figure 2 , there is an S1 interface between the core network and the base station (macro base station), and there is an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or can be connected to the core network through the home base station gateway. There is no X2 interface between the home base station and the macro base station. The UE is located in the cell to which the macro base station (or home base station) belongs and is in a connected state. The UE has a list of CSG cells that are allowed to access.

[0070] The macro base station (or home base station) sends a measurement control message to the UE, wherein the measurement control message includes measurement identifier 1 and measurement identifier 2 (measurement identifier 1 corresponds to frequency f1 and measurement event A4; measurement identifier 2 corresponds to fr...

Abstract

The invention discloses a method for reporting a measuring report of a CSG cell, which can quicken the process of switching to the CSG cell. The method comprises that when discovering that an adjacent CSG cell is a usable adjacent CSG cell in the measuring process, user equipment UE in a connected state immediately reports the measurement report containing the CSG cell to a network side.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a measurement report reporting method for a closed subscriber group (Closed Subscriber Group, CSG for short) cell. Background technique [0002] In a mobile communication system, in order to meet mobility requirements, after a user equipment (UE) establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its neighboring cells in order to select a suitable cell. The cell is switched. Taking EUTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) as an example, the specific process of UE measurement in connected state is: the network side sends a measurement control message to the UE, wherein the measurement control message includes measurement Identification (measurement identity, referred to as MID), event type, measurement object, and attributes to be measure...
