Embodiment 1

[0079] The terminal and the network side respectively store two CSG lists, one allowed CSG list controllable by the user and the operator, and one operator CSG list controllable only by the operator.

[0080] When the terminal receives the command to delete the CSG ID under the operator's CSG list, it prompts that it cannot be changed, or the terminal does not display the operator's CSG list, so as to prevent the user from changing it.

[0081] The terminal performs automatic network selection according to the operator CSG list and the allowed CSG list, and the specific scheme is as follows:

[0082] The terminal sequentially performs automatic network selection on the CSG IDs in the operator CSG list and the allowed CSG list, or the terminal performs automatic network selection on the CSG IDs in the allowed CSG list and the operator CSG list in sequence.

[0083] When a terminal accesses a CSG cell, if it receives a NAS rejection message and the error code is #25, the specifi...

Embodiment 2

[0094] The terminal and the network side respectively store two CSG lists, one allowed CSG list controllable by the user and the operator, and one operator CSG list controllable only by the operator.

[0095] When the terminal receives the command to delete the CSG ID under the operator's CSG list, it prompts that it cannot be changed, or the terminal does not display the operator's CSG list, so as to prevent the user from changing it.

[0096] The terminal performs automatic network selection according to the operator CSG list and the allowed CSG list, and the specific scheme is as follows:

[0097] The terminal combines the operator's CSG list and the CSG ID in the allowed CSG list to generate a merged CSG list. The method for generating the merged list may be that the terminal combines the CSG ID in the operator's CSG list with the CSG ID in the allowed CSG list. The CSG IDs that do not exist in the operator's CSG list are combined to generate a merged CSG list; then, accor...

Embodiment 3

[0108] The terminal and the network side respectively store two CSG lists, one allowed CSG list controllable by the user and the operator, and one operator CSG list controllable only by the operator.

[0109] When the terminal receives the command to delete the CSG ID under the operator's CSG list, it prompts that it cannot be changed, or the terminal does not display the operator's CSG list, so as to prevent the user from changing it.

[0110] The terminal performs automatic network selection according to the operator CSG list and the allowed CSG list, and the specific scheme is as follows:

[0111] The terminal generates an available operator CSG list, and according to the available operator CSG list and the allowed CSG list, sequentially performs automatic network selection for the CSG IDs in the list.

[0112] The process for the terminal to generate an available operator CSG list includes: the terminal acquires a CSG ID, and generates an available operator CSG list from t...

Abstract

The embodiment of the invention discloses a method and a terminal for an operator to control a closed subscriber group list, relates to the technical field of communications, and can guarantee that CSG IDs (Closed Subscriber Group IDs) controlled by the operator are not updated in the manner of NAS (Network Attached Storage) signaling. The method disclosed in the embodiment comprises the steps that: the terminal saves a permitted CSG list and an operator CSG list; according to the permitted CSG list and the operator CSG list, the terminal performs network selection automatically; the terminal requests the access to a CSG cell, and if a denial message is received, the operator CSG list and / or the permitted CSG list contains a CSG ID of the CSG cell, the terminal deletes the CSG ID in the permitted CSG list and maintains the CSG ID in the operator CSG list; and if an acceptance message is received, the permitted CSG list does not contain the CSG ID of the CSG cell and the CSG ID is added to the permitted CSG list.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and a terminal for an operator to control a closed subscriber group (Closed Subscriber Group, CSG). Background technique [0002] In order to provide a higher data transmission rate, less delay, and reduce the operator's operating costs, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) proposed a HeNB (Home eNodeB, evolved home base station) ) access service. This kind of service deploys HeNB in ​​places such as homes, shopping malls or enterprises. As a private device, HeNB only allows specific user groups to access EPS (Evolved Packet System) through HeNB and obtain higher data transmission rates. or other special services. These user groups that are allowed to access the network through the HeNB are called CSG (Close subscriber group, closed user group). [0003] According to the definition of 3GPP, each CSG has a unique ...
