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

1 . A home base station (HNB) which communicates with a home base station gateway (HNB-GW), the HNB comprising:
a transmission circuit configured to transmit, to the HNB-GW as part of a user equipment (UE) registration procedure for a UE, UE register request message, wherein the transmission circuit is further 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; and a receiving circuit configured to receive, from the HNB-GW as part of the HNB registration procedure, a HNB register accept message; wherein the receiving circuit is further configured to receive, as part of the UE registration procedure when 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 . A home base station gateway (HNB-GW) which communicates with a home base station (HNB), the HNB-GW comprising:
a receiving circuit configured to receive, from the HNB as part of a user equipment (UE) registration procedure for a UE, UE register request message, wherein the receiving circuit is further configured to receive, from the HNB 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; a transmission circuit configured to transmit, to the HNB as part of the HNB registration procedure, a HNB register accept message; and a controller for performing access control for the UE on the HNB;
wherein the transmission circuit is further configured to transmit, to the HNB as part of the UE registration procedure when the access control performed for the UE is successful, a UE register accept message including a context ID of a UE.

3 . A method performed by a home base station (HNB) which communicates with a home base station gateway (HNB-GW), the method comprising:
transmitting, to the HNB-GW as part of a user equipment (UE) registration procedure for a UE, UE register request message, transmitting, 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; receiving, from the HNB-GW as part of the HNB registration procedure, a HNB register accept message; and receiving, as part of the UE registration procedure when 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 . A method performed by a home base station gateway (HNB-GW) which communicates with a home base station (HNB), the method comprising:
receiving, from the HNB as part of a user equipment (UE) registration procedure for a UE, UE register request message, receiving, from the HNB 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; transmitting, to the HNB as part of the HNB registration procedure, a HNB register accept message; performing access control for the UE on the HNB; and transmitting, to the HNB as part of the UE registration procedure when the access control performed for the UE is successful, a UE register accept message including a context ID of a UE.

5 . A user equipment (UE) which communicates with a home base station (HNB) that communicates 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 an 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 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 and receives, from the HNB-GW as part of the HNB registration procedure, a HNB register accept message, and 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 receives, when access control performed at the HNB-GW for the UE is successful, a UE register accept message including a context ID of a UE.

6 . A method performed by a user equipment (UE) which communicates with a home base station (HNB) that communicates with a home base station gateway (HNB-GW), the method comprising: establishing an 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 and receives, from the HNB-GW as part of the HNB registration procedure, a HNB register accept message, and 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 receives, when access control performed at the HNB-GW for the UE is successful, a UE register accept message including a context ID of a UE.
