Abstract:
Some embodiments provide novel techniques for supporting CSG features without mobile operators having to upgrade their core network (CN). To support the CSG features, a home node B (HNB) gateway (HNB-GW) and/or the HNB performs functions (e.g. access control) that would normally be performed by a mobile operator's CN if the CN has been upgraded to support the CSG features. Accordingly, by performing access control the HNB-GW and/or the HNB, the mobile operator does not have to upgrade the CN to support CSG operations.
Abstract:
Some embodiments provide a method and technique for explicitly indicating the start of a communication session within an Unlicensed Mobile Access (UMA) network or Generic Access Network (GAN). To facilitate the explicit indication of the start of the communication session, some embodiments replace the first DIRECT TRANSFER message exchanged between a user equipment (UE) and network controller of the UMA network or GAN with a new message, the GA-RRC INITIAL DIRECT TRANSFER message. Some embodiments also provide a method and technique to activate a communication channel prior to performing handover from a first licensed wireless communication network to the UMA network or GAN. In this manner, some embodiments perform a more efficient and seamless handover from the licensed wireless network as the delay resulting from the handover is minimized by performing the channel activation procedure prior to the handover.
Abstract:
Some embodiments provide a method of registering a user equipment (UE) in a communication system that includes a licensed wireless communication system and a generic access network (GAN) that has a generic access network controller (GANC). The method sends a register request message from the UE to the GANC that indicates a GAN mode capability of A/Gb only for the UE. When the GANC has a GAN mode capability of A/Gb, the GANC registers the UE with the GAN. When the GANC has a GAN mode capability of Iu only, the GANC rejects the register request message. When the GANC has a GAN mode capability of both A/Gb and Iu, the GANC registers the UE based on a set of GANC mode selection rules that the GANC applies for registering UEs with the GAN.
Abstract:
Some embodiments of the invention provide a communication system that includes a first communication network, a second communication network, and a core network. The second communication network includes a network controller and a group of two or more access areas that are communicatively coupled to the core network by the network controller. Some embodiments service the second network access areas by providing access area identifiers to each access area while communicating with the first network or core network using a single area identifier assigned to the network controller. Some embodiments provide access control by sending a series of invalid messages to a user equipment (UE) that is not authorized to access services of the second network to reject the UE. Some embodiments reject the UE by sending a message to ban a UE from an access area with a particular access area identifier.

Abstract:
Some embodiments provide a method for updating registration information of a user equipment (UE) in a communication system that includes several evolved Universal Mobile Telecommunication System (UMTS) Terrestrial Radio Access Network (E-UTRANs) that communicatively couple the UE to a Voice over long term evolution (LTE) via Generic Access (VoLGA) network controller (VANC). The method receives a message at the UE from the VANC including a list of E-UTRAN tracking areas (TAs) served by the VANC, each tracking area identified by a tracking area identifier (TAI). The method stores the list of E-UTRAN tracking areas at the UE. The method sends a register update message that includes a TAI of a particular E-UTRAN tracking area from the UE to the VANC when the UE moves into the particular E-UTRAN tracking area and the particular E-UTRAN TAI is not in the list of E- UTRAN tracking areas (TAs) served by the VANC.
Abstract:
Some embodiments are implemented in a communication system that includes a first communication system comprised of a licensed wireless radio access network and a core network, and a second communication system comprising a plurality of user hosted access points and a network controller. In some embodiments, each access point operates using short range licensed wireless frequencies to establish a service region. In some embodiments, the network controller communicatively couples the core network to the plurality of access points. The method establishes a communication through a Radio Access Network Application Part (RANAP) message from an access point to the network controller to explicitly indicate the start of a communication session. The method then passes a set of direct transfer messages, comprised in part of the RANAP message, to the core network.

Abstract:
Some embodiments are implemented in a communication system that includes a first wireless communication system and a second wireless communication system that includes a Femtocell access point (FAP) and a network controller that can communicatively couple the FAP to the first wireless communication system. In some embodiments, the network controller can communicatively couple to the first wireless communication system through a UTRAN Iu interface. Some embodiments provide a resource management method that determines that a user equipment (UE) has roved in a region serviced by the FAP. The FAP includes a generic access resource control (GA-RC) protocol sub-layer. The method creates a separate GA-RC state dedicated to the UE in the GA-RC protocol sub-layer. The method also sets the GA-RC state dedicated to the UE to a deregistered state to indicate that the UE is not registered to use the services of the second wireless communication system.
Abstract:
A method of providing high availability for an Iuh based communication system is described. The communication system includes a first communication system with a core network and a licensed radio access network and a wireless second communication system with a short range access point and a network controller that communicatively couples the access point to the core network to establish a set of user plane sessions. When a set of ongoing user plane sessions exists, the method determines that there is a loss of signaling connectivity between the access point and the network controller. The method maintains resources assigned to the access point for the set of ongoing sessions after the loss of the signaling connectivity and reestablishes the signaling connectivity between the access point and the network controller. The method restores one or more of the ongoing sessions over the reestablished connectivity using the maintained resources.
