Abstract

A communication apparatus which communicates with a base station, the communication apparatus includes a receiving circuit configured to receive a message from the base station, wherein the message includes at least information identifying if the base station is a hybrid access mode base station; and a transmission circuit configured to transmit a parameter which identifies a user equipment to the base station when the base station is the hybrid access mode base station.

First claim

The invention claimed is:

1. A user equipment (UE) configured to communicate with a home base station (HNB), which is configured to communicate with a home base station gateway (HNB-GW), the UE comprising:
a controller; and
a transceiver,
wherein the controller is configured to control the transceiver to establish a Radio Resource Control (RRC) connection with the HNB and to transmit a message carrying an initial non-access stratum (NAS) message to the HNB comprising a UE identity,
wherein the HNB is configured to transmit, to the HNB-GW as part of a HNB registration procedure, a HNB register request message,
wherein the HNB register request message includes at least information identifying whether the HNB operates in one of an open mode, a hybrid mode and a closed mode,
wherein the HNB is configured to receive, from the HNB-GW as part of the HNB registration procedure, a HNB register accept message,
wherein the HNB is configured to, after receipt of the initial NAS message, transmit, to the HNB-GW as part of a user equipment (UE) registration procedure for the UE, a UE register request message, and
wherein the HNB is configured to receive, if access control performed at the HNB-GW for the UE is successful, a UE register accept message including a context ID of a UE.

2. The UE according to claim 1 , wherein the HNB registration procedure registers the HNB with the HNB-GW and enables the HNB-GW to provide service and core network connectivity for the HNB.

3. A method performed by a user equipment (UE), which communicates with a home base station (HNB), which communicates with a home base station gateway (HNB-GW), the method comprising:
establishing a Radio Resource Control (RRC) connection with the HNB; and
transmitting a message carrying an initial non-access stratum (NAS) message to the HNB the message comprising a UE identity,
wherein the HNB transmits, to the HNB-GW as part of a HNB registration procedure, a HNB register request message,
wherein the HNB register request message includes at least information identifying whether the HNB operates in one of an open mode, a hybrid mode and a closed mode,
wherein the HNB receives, from the HNB-GW as part of the HNB registration procedure, a HNB register accept message,
wherein after receipt of the initial NAS message, the HNB transmits, to the HNB-GW as part of a user equipment (UE) registration procedure for the UE, a UE register request message, and
wherein the HNB receives, if access control performed at the HNB-GW for the UE is successful, a UE register accept message including a context ID of a UE.

4. The method according to claim 3 , wherein the HNB registration procedure registers the HNB with the HNB-GW and enables the HNB-GW to provide service and core network connectivity for the HNB.
