Problems solved by technology

[0009] After the UE reports the proximity indication (Proximity Indication) to the network side, the UE cannot immediately detect the authorized CSG / Hybrid cell whose signal meets the conditions, and the UE cannot immediately switch to the authorized CSG / Hybrid cell, and the UE may still Handover to other macro cells. After switching to other macro cells, the UE needs to re-report the proximity indication to the newly handed over cell (target cell). After receiving the proximity indication, the target cell performs corresponding processing. This method wastes air interface resources , and the handover of the UE to the authorized CSG / Hybrid cell is delayed

Embodiment 1

[0071] In the LTE system, the UE is located in the cell 1 under the jurisdiction of the macro base station (base station 1, in this embodiment, the source base station) and is in the connected state. The current cell is allowed to report the proximity indication or has the ability to support handover to the closed subscriber group cell (reportProximityConfig is set to allowed). The source network side configures the measurement configuration for the UE, and the UE performs measurement according to the measurement configuration, and reports cell information that meets the reporting conditions.

[0072] Such as image 3 shown, including:

[0073] Step 301. At a certain moment, the UE determines to be close to a previously authorized CSG or Hybrid cell according to the saved footprint or fingerprint information, and the UE reports the proximity indication to the source network side, and the proximity indication includes the CSG cell or Hybrid cell. Frequency information of the ...

Embodiment 2

[0087] In the LTE system, the UE is located in cell 1 under the jurisdiction of the macro base station (base station 1, source network side) and is in the connected state. The current cell supports the ability to switch to a closed subscriber group cell (reportProximityConfig is set to allowed). The network side configures the measurement configuration for the UE, and the UE performs measurement according to the measurement configuration, and reports cell information that meets the reporting conditions.

[0088] Such as Figure 4 shown, including:

[0089] Step 401, at a certain moment, the UE determines to be close to a previously authorized CSG or Hybrid cell according to the saved footprint or fingerprint information, and the UE reports the proximity indication to the network side, and the proximity indication includes the CSG cell or Hybrid cell frequency information (frequency f1) and access network technology (E-UTRAN).

Embodiment 3

[0097] In the LTE system, the UE is located in cell 1 under the jurisdiction of the macro base station (base station 1, source network side) and is in the connected state. The current cell supports the ability to switch to a closed subscriber group cell (reportProximityConfig is set to allowed). The source network side configures the measurement configuration for the UE, and the UE performs measurement according to the measurement configuration, and reports cell information that meets the reporting conditions.

[0098] Such as Figure 5 shown, including:

[0099] Step 501, at a certain moment, the UE determines to be close to a previously authorized CSG or Hybrid cell according to the saved footprint or fingerprint information, and the UE reports the proximity indication to the network side, and the proximity indication includes the CSG cell or Hybrid cell frequency information (frequency f1) and access network technology (E-UTRAN).

[0100] Step 502, after the network side ...

Abstract

The invention provides a method for processing proximity indication during switching, comprising the following steps: in the switching process, a source network side or user equipment sends the proximity indication information to a target network side; after the proximity indication information is received, the target network side configures the information related to closed user group region for the user equipment. The invention further provides a system for processing proximity indication when switching. In the invention, the proximity indication information is sent to the target network side in the switching process to reduce empty signaling so that the target base station indicates UE (User Equipment) to obtain the system information of CSG/Hybrid region as far as possible and the UE can carry out the switching on the authorized CSG/Hybrid region as far as possible.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and system for processing proximity indication during handover. Background technique [0002] In the construction of wireless network systems, indoor coverage has become the top priority of network construction. On the one hand, a reasonable indoor coverage scheme can maximize the role of the network system and create greater value for operators. It can also greatly save the network construction cost of operators, and truly realize low investment and high return. As a result, a wireless access device called a home base station (Home eNodeB, HeNB) emerges as the times require. As the exclusive resources of private users, femtocells are deployed in private places such as families, groups, companies or schools. They can provide users with various high-speed wireless access services and provide preferential tariffs, and at the same time make up for the existing d...
