Abstract:
Some embodiments provide a system for authorization and authentication of an unlicensed mobile access (UMA) subscriber. The system includes an UMA network controller (UNC) which is communicatively coupled to a licensed wireless communication system. The system also includes an access point (AP) that serves a wireless local area network (WLAN). The system further includes a mobile station (MS) that is communicatively coupled to the AP and the licensed wireless communication system. The system also includes an authentication server that is communicatively coupled to the UNC. The authentication server authenticates a UMA subscriber for accessing an unlicensed mobile access network (UMAN) that includes the UNC and the AP. Some embodiments define an interface between the UNC and the authentication server uses Remote Access Dial-In User Service (RADIUS) protocol. In some embodiments, the authentication server is an Authorization, Authentication, and Accounting (AAA) server.
Abstract:
A method of cell updating system that includes a first wireless communications system that has a core network and a second wireless communications system that includes several short range access points using licensed wireless frequencies and a network controller for communicatively coupling a user equipment to the core network. The UE has one or more active sessions on a first access point. There is no dedicated radio channel between the UE and the first access point. The method receives a cell update message from the UE. The method sends a cell update request message from the second access point to the network controller. The cell update request message is for sending from the network controller to the first access point to request information for handling the cell update message received by the second access point. The method receives a cell update response message from the network controller.
Abstract:
Techniques for performing messaging between mobile stations (MSs) and UMA network controllers (UNCs) in an unlicensed mobile access network (UMAN). URR (UMA radio resource) messages are exchanged between an MS and one or more UNCs to perform various operations associated with UMAN. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.
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 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:
Methods for performing various operations via unlicensed mobile access (UMA) radio link control (URLC) messages in an unlicensed mobile access network (UMAN). The UMAN comprises a first radio access network that may be employed for accessing data services provided by a core network comprising a second radio access network. URLC messages are exchanged between mobile stations (MSs) and UMA network controllers (UNCs) to perform various operations associated with the UMAN: An MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to a UNC via an IP network. The URLC messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.
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:
Some embodiments provide a system [300] for handling communications between an unlicensed mobile access (UMA) [105] network controller (UNC) [315] and a licensed wireless communication system. The system of these embodiments include a serving general packet radio service support node (SGSN) [350] or a mobile switching center (MSC) [360] that is communicatively coupled to the UNC. In such systems the UNC and the SGSN communicate utilizing a subset of a protocol standard message set. The protocol standard message set includes message for handing discovery and registration, circuit switching domain and packet switching domain signaling, and circuit switching based data and packet switching based data. The subset for the SGSN is for handling packet switching domain signals and packet switching based data. The subset for the MSC is for handling circuit switching domain and circuit switching based data.
