Problems solved by technology

When the UE approaches a CSG member cell of an unregistered operator, but the PLMN ID corresponding to the CSG member cell is not in the EPLMN list, the UE cannot report to the network side that the CSG member cell is also a CSG member cell, so the UE’s service The base station cannot handover the UE to the CSG member cell, thus affecting the UE's enjoyment of the member treatment of the CSG member cell

Embodiment 1

[0087] Example 1: X2 HO

[0088] The base station configures whether the UE activates the proximity indication function on other PLMNs (that is, PLMNs other than the PLMN currently registered by the UE and the PLMNs in the EPLMN list).

[0089] On the premise that the proximity indication function on other PLMNs is activated, when the UE approaches a cell in the CSG whitelist, it enters the coverage of the CSG cell, and the signal strength of the CSG cell reaches the preset threshold value , the UE sends a proximity indication message to the serving base station, which carries the frequency of the PLMN of the CSG cell, and may further carry the PLMN ID.

[0090] When the UE approaches the target CSG cell, because the UE knows the ID of the currently registered PLMN and the EPLMN list, it can determine whether the target CSG cell is a CSG cell under another PLMN according to the PLMN ID corresponding to the CSG ID of the target CSG cell. The target CSG cell is a CSG cell under...

Embodiment 2

[0111] Example 2: S1 HO

[0112] The base station configures whether the UE activates the proximity indication function on other PLMNs (that is, PLMNs other than the PLMN currently registered by the UE and the PLMNs in the EPLMN list).

[0113] On the premise that the proximity indication function on other PLMNs is activated, when the UE approaches a cell in the CSG whitelist, it enters the coverage of the CSG cell, and the signal strength of the CSG cell reaches the preset threshold value , the UE sends a proximity indication message to the serving base station, which carries the frequency of the PLMN of the CSG cell, and may further carry the PLMN ID.

[0114]When the UE approaches the target CSG cell, because the UE knows the ID of the currently registered PLMN and the EPLMN list, it can determine whether the target CSG cell is a CSG cell under another PLMN according to the PLMN ID corresponding to the CSG ID of the target CSG cell. The target CSG cell is a CSG cell under ...

Embodiment 3

[0123] Embodiment 3: intra-eNB HO

[0124] The base station configures whether the UE activates the proximity indication function on other PLMNs (that is, PLMNs other than the PLMN currently registered by the UE and the PLMNs in the EPLMN list).

[0125] On the premise that the proximity indication function on other PLMNs is activated, when the UE approaches a cell in the CSG whitelist, it enters the coverage of the CSG cell, and the signal strength of the CSG cell reaches the preset threshold value , the UE sends a proximity indication message to the serving base station, which carries the frequency of the PLMN of the CSG cell, and may further carry the PLMN ID.

[0126] When the UE approaches the target CSG cell, because the UE knows the ID of the currently registered PLMN and the EPLMN list, it can determine whether the target CSG cell is a CSG cell under another PLMN according to the PLMN ID corresponding to the CSG ID of the target CSG cell. The target CSG cell is a CSG ...

Abstract

The present invention discloses a closed subscriber group CSG cell switching method, equipment and system, which are used to switch a UE to a specific public land mobile network PLMN. The specific PLMN is a list of equivalent PLMNs in addition to the PLMN currently registered by the UE. CSG cells in PLMNs other than PLMNs in the EPLMN list. A CSG cell switching method provided by the present invention includes: receiving a proximity indication message sent by the user equipment UE when it is close to a target CSG cell, where the target CSG cell is a CSG cell in a specific PLMN of the UE, and the specific PLMN is PLMNs other than the PLMN currently registered by the UE and the PLMN in the equivalent PLMN list EPLMN list; handover the UE to the target CSG cell according to the proximity indication message.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a closed subscriber group (Closed Subscriber Group, CSG) cell handover method, equipment and system. Background technique [0002] The CSG function can provide member users with a higher access level and faster service rate, and can also implement a special charging mode based on the CSG cell. After user equipment (User Equipment, UE) subscribes to become a member user of some CSG cells, it can obtain a higher access level and a higher service rate. A UE may subscribe to become CSG members of multiple Public Land Mobile Networks (Public Land Mobile Network, PLMN) at the same time. [0003] The home base station (Home Node B, HNB) and the evolved home base station (Home evolved Node B, HeNB) are low-power small base stations, which can provide users with higher rates within a small coverage area, and can also Solve coverage problems for operators in location...
