Abstract
Aspects of the disclosure provide a method for avoiding reselection of fake cell. The method includes transmitting a first request for network service of a wireless communication network in a first cell from user equipment, receiving a first reject message without integrity protection, adding the first cell to a set-aside cell list, and selecting a cell from other cells that are not included in the set-aside cell list to request network service.
Claims22
A method, comprising:
- transmitting a first request for a network service in a first cell of a wireless communication network of a radio access technology (RAT) belonging to a selected public land mobile network (PLMN) from user equipment;
- receiving a first reject message without integrity protection in the first cell of the wireless communication network of the RAT belonging to the selected PLMN at the user equipment;
- in response to receiving the first reject message, adding the first cell of the wireless communication network of the RAT belonging to the selected PLMN to a set-aside cell list that uses a cell identity (ID) to represent each cell on the set-aside cell list, wherein each cell on the set-aside cell list is added to the set-aside cell list in response to receiving a reject message without integrity protection in the respective cell;
- and
- in response to receiving the first reject message, selecting a cell from other cells of the wireless communication network of the RAT belonging to the selected PLMN that are not included in the set-aside cell list to request the network service, wherein the selected cell and the first cell belong to the same PLMN, and are of the same RAT.

User equipment, comprising processing circuitry configured to:
- transmit a first request for a network service in a first cell of a wireless communication network of a radio access technology (RAT) belonging to a selected public land mobile network (PLMN) from user equipment;
- receive a first reject message without integrity protection in the first cell of the wireless communication network of the RAT belonging to the selected PLMN;
- in response to receiving the first message, add the first cell of the wireless communication network of the RAT belonging to the selected PLMN to a set-aside cell list that uses a cell identity (ID) to represent each cell on the set-aside cell list, wherein each cell on the set-aside cell list is added to the set-aside cell list in response to receiving a reject message without integrity protection in the respective cell;
- and
- in response to receiving the first reject message, select a cell from other cells of the wireless communication network of the RAT belonging to the selected PLMN that are not included in the set-aside cell list to request the network service, wherein the selected cell and the first cell belong to the same PLMN, and are of the same RAT.

A non-transitory computer readable medium storing program instructions for causing a processor to perform operations, the operations comprising:
- transmitting a first request for a network service in a first cell of a wireless communication network of the wireless communication network of the RAT belonging to the selected PLMN from user equipment;
- receiving a first reject message without integrity protection in the first cell of the wireless communication network of the RAT belonging to the selected PLMN at the user equipment;
- in response to receiving the first reject message, adding the first cell of the wireless communication network of the RAT belonging to the selected PLMN to a set-aside cell list that uses a cell identity (ID) to represent each cell on the set-aside cell list, wherein each cell on the set-aside cell list is added to the set-aside cell list in response to receiving a reject message without integrity protection in the respective cell;
- and
- in response to receiving the first reject message, selecting a cell from other cells of the wireless communication network of the wireless communication network of the RAT belonging to the selected PLMN that are not included in the set-aside cell list to request the network service, wherein the selected cell and the first cell belong to the same PLMN, and are of the same RAT.
