Problems solved by technology

It can be seen that for the Inboud handover process of a UE without CSG capability, because the macro base station or the home base station that initiates the handover cannot predict the subscription information between the UE IMSI and the target home base station, many unnecessary handover procedures will be initiated, and these handovers Process may fail

Embodiment 1

[0048] Such as image 3 As shown, this embodiment is mainly aimed at the decision whether to switch to the target CSG cell after the source network element acquires the CSG list signed with the UE IMSI after the UE directly enters the macro base station (or home base station) without introducing new signaling. Processing flow:

[0049] Step 301: After the UE completes the access procedure, the RNC (or home base station) judges that the UE does not support CSG according to the indication of whether to support CSG or the version information carried in the UE air interface capability information;

[0050] Step 302: The RNC (or home base station) notifies the CN of whether the UE supports the CSG capability in the Initial UE Message (initial UE message) sent to the CN. If the UE does not support the CSG capability, the core network can pass the RAB ASSIGNMENT REQUEST (RAB assignment request message) sends the UE's IMSI subscribed CSG list to the RNC;

[0051] Step 303: The RNC (...

Embodiment 2

[0055] Such as Figure 4 As shown, this embodiment is mainly aimed at the processing flow of deciding whether to switch to the target CSG cell after the UE directly enters the source cell, and obtains the CSG list signed with the UE IMSI by introducing a new signaling source network element:

[0056] Step 401: After the UE completes the access procedure, the RNC (or home base station) judges that the UE does not support CSG according to the indication of whether to support CSG or the version information carried in the UE air interface capability information;

[0057] Step 402: The RNC (or the home base station) completes the acquisition of the CSG list subscribed by the UE IMSI through a newly added query interaction message;

[0058] First, the RNC (or home base station) sends the white list acquisition request information (ALLOWEDCSG LIST REQUIRED) to the CN. After the CN receives it, it judges which UE the request is for according to its signaling connection, and then sends...

Embodiment 3

[0063] Such as Figure 5 As shown, this embodiment involves two source RNCs (or home base stations), RNC2 (or home base station 2) is the current source network element, and RNC1 (or home base station 1) initiates handover to RNC2 (or home base station 2) network element. This embodiment is mainly aimed at UE entering the source cell through handover, and carrying the CSG list information subscribed by IMSI in the relocation request, and RNC2 (or home base station 2) obtains the CSG subscribed by UE IMSI without introducing new signaling The processing flow of deciding whether to switch to the target CSG cell after the list.

[0064] Step 501: the source RNC1 (or home base station 1) sends a relocation request (RelocationRequired) to the core network, and carries no The list of CSGs subscribed by UEIMSI supporting CSG capability;

[0065] In other embodiments, the UE IMSI-subscribed CSG list may also be carried in other information elements of other messages, and the ultima...

Abstract

The invention discloses a control method of switching from a non CSG terminal to a CSG cell, which can effectively avoid blind switching. The method comprises the steps that a source network element acquires the access control information of UE which does not support CSG capacity in advance, and then determines whether to initiate a switching process according to the access control information.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for performing access control during the handover process of a terminal not supporting CSG capability to a CSG cell of a home base station. Background technique [0002] Home NodeB (Home NodeB, HNB) is a small, low-power base station that is deployed in indoor places such as homes and offices. Its main function is to provide users with higher service rates and reduce the cost of using high-rate services. At the same time, it makes up for the lack of coverage of existing distributed cellular wireless communication systems. The advantages of femto base stations are affordable, convenient, low power output, plug and play, etc. [0003] The HNB user is connected to the core network network through the HNB Access Network (Home NodeB Access Network, HNB AN), where the HNB AN is composed of the HNB and the HNB Gateway (Home NodeB Gateway, HNB GW). The main ...
