Abstract

A cell access control method and a user terminal are provided, the method includes: obtaining, by a user equipment (UE), cell access information through a pilot channel and/or a synchronization channel; determining a current cell is a macro base station cell or an HNB cell according to the cell access information; determining, when the current cell is an HNB cell, whether the UE is allowed to access the HNB cell according to HNB information of the cell access information, if the UE is allowed to access the HNB cell, performing the access processing, if the UE is not allowed to access the HNB, abandoning the access. A UE is provided accordingly.

Claims

1. A cell access control method, comprising:

sending, by a home eNodeB (HNB), cell access information to a user equipment (UE) through a synchronization channel; and

implementing, by the HNB, an access processing of the UE, the access processing is initiated by the UE after the UE is determined to be allowed to access a HNB cell by comparing the cell access information sent through the synchronization channel with HNB information stored in UE memory, wherein the determination of the UE is allowed to access the HNB cell is performed after a cell is determined as the HNB cell according to the cell access information sent through the synchronization channel.

2. The method of claim 1, wherein the cell access information comprises:

cell identifier information.

3. The method of claim 1, the method further comprises:

generating, by the HNB, pseudo-scramble information according to a preset rule; and

calculating, by the HNB, the cell access information according to the pseudo-scramble information.

4. The method of claim 1, wherein the HNB information includes an HNB list, and the HNB list includes at least one HNB that allows the UE to be accessed.

5. A home eNodeB (HNB), comprising:

a transmitter, configured to send cell access information to a user equipment (UE) through a synchronization channel; and

a processor, configured to implement an access processing of the UE, the access processing is initiated by the UE after the UE is determined to be allowed to access a HNB cell by comparing the cell access information sent through the synchronization channel with HNB information stored in UE memory, wherein the determination of the UE is allowed to access the HNB cell is performed after a cell is determined as the HNB cell according to the cell access information sent through the synchronization channel.

6. The HNB of claim 5, wherein the cell access information comprises:

cell identifier information.

7. The HNB of claim 5, wherein the processor further configured to generate pseudo-scramble information according to a preset rule, and calculate the cell access information according to the pseudo-scramble information.

8. The HNB of claim 5, wherein the HNB information includes an HNB list, and the HNB list includes at least one HNB that allows the UE to be accessed.
