US 9,288,726 B2 · Systems and methods for obtaining subscriber access information by a core network in a handover process

Abstract

The present invention discloses a method for a core network to obtain user access information during a handover procedure, which includes: when the user handovers between HNBs or HeNBs and the core network does not carry out access control of the user, if the destination HeNB is connected to the core network directly or the user which does not support a closed subscriber group handovers to a hybrid destination HNB, the network element which controls the access of the user transmitting membership information of the user to the core network. The invention also discloses a corresponding system. The invention realizes that under the condition that the RAN side controlling the access of the UE during the handover process and the CN cannot know the membership of the UE, the RAN side notifying the core network of the membership information of the UE and the information of the H(e)NB.

A method for a core network to obtain access information of a user during a handover process, comprising:

when the user handovers between HNBs (home NodeBs) or HeNBs (home eNodeBs) and the core network does not carry out access control of the user,
when a destination HeNB is connected to the core network directly or a user which does not support a closed subscriber group handovers to a hybrid destination HNB, a radio access network element which carries out the access control of the user transmitting membership information of the user to the core network after the access control of the user for the handover.

A method for a core network to obtain access information of a user during a handover process, comprising:

when the user handovering between HNBs belonging to a same HNB gateway, and the core network does not carry out access control of the user, a destination HNB or the HNB gateway transmitting the access information of the user to the core network after the access control of the user for the handover;
and
when the user handovering between HeNBs belonging to a same HeNB gateway, and the core network does not carry out access control of the user, a destination HeNB or the HeNB gateway transmitting the access information of the user to the core network after the access control of the user for the handover.

A system for a core network to obtain access information of a user during a handover process, comprising:

a source HNB, a destination HNB, a source HNB gateway, a destination HNB gateway and a core network, wherein,
when the user handovers between the source HNB and the destination HNB and the core network does not carry out access control,
the destination HNB gateway is configured to carry out access controlling of the user and transmit membership information of the user to the core network after the access control of the user for the handover when the user which does not support closed subscriber group handovers to a hybrid destination HNB,
and,
when the source HNB gateway and the destination HNB gateway are a same HNB gateway and the core network does not carry out access control, the same HNB gateway or the destination HNB gateway is configured to transmit the membership information of the user to the core network after the access control of the user for the handover.

A system for a core network to obtain access information of a user during a handover process, comprising:

a source HeNB, a destination HeNB and a mobile management entity, wherein,
when the destination HeNB is connected to the mobile management entity directly, the destination HeNB is configured to transmit membership information of the user to the mobile management entity when the user handovers between the source HeNB and the destination HeNB and the core network does not carry out access control;
when the system further comprises a HeNB gateway and the HeNB gateway is connected to the mobile management entity,
the HeNB gateway is configured to transmit the access information of the user to the mobile management entity when the user handovers between HeNBs belonging to a same HeNB gateway and the core network does not carry out access control, or
the destination HeNB is configured to transmit the access information of the user to the mobile management entity when the user handovers between the HeNBs belonging to the same HeNB gateway and the core network does not perform access control.
