摘要:
Method and arrangement in a network control node, for performing access control of a mobile node in a handover from a source cell to a target subscriber group cell. The method comprises obtaining a network based allowed subscriber group list, receiving a target subscriber group identification, checking if the target subscriber group identification is comprised in the obtained network based allowed subscriber group list. If it is, information from a target network control node is obtained, verifying that the received subscriber group identification corresponds to the target subscriber group cell. Still further, the method comprises granting the mobile node access to the target subscriber group cell. Also, a method and arrangement in a target network control node, for assisting a network control node in performing access control for a mobile node in a handover from a source cell to a target subscriber group cell is provided.
摘要:
A method and system for limiting redirections of a mobile station (MS) in an unlicensed radio access network having a plurality of unlicensed network controllers (UNCs). The MS includes a redirection counter set to zero within a registration request sent to one of the UNCs. Each time the MS receives a redirection response from a UNC, the MS increments the redirection counter and sends it in another registration request. Once the redirection counter has exceeded a defined value for the MS, the UNC rejects any registration request from that MS.

The present invention relates to methods and devices that allow for efficient transportation of traffic in conjunction with a home base station (1). Traffic arriving in the home base station from a mobile terminal (2) connected to the home base station can be transported by means of local breakout transportation, which implies that the traffic is forwarded to a local node (4) over a local network (20) or to the Internet (21) without passing a core network (15) of a mobile telecommunications system. A local breakout bearer (22) is established, which is a radio bearer that extends between the mobile terminal and the home base station. The mobile terminal forwards uplink traffic that is to be subject to local breakout transportation to the home base station on the local breakout bearer. Thus it is not required for traffic that is destined for local nodes or the Internet to pass the core network, which allows for efficient traffic forwarding.
摘要:
A system, method, and apparatus in an access network such as the Generic Access Network (GAN) for providing user-type information to a Security Gateway (SEGW) or for enabling the SEGW to obtain user-type information for different user types so that the SEGW can apply specific security functions based on the user type. The invention may also provide user-type information to a controller node such as a GAN Controller (GANC) or may enable the GANC to obtain user-type information for application of security settings toward GAN-clients. An Authentication, Authorization and Accounting (AAA) Server may create a user-type indication internally, or may obtain an indication from a Home Location Register and forward the indication to the SEGW. The SEGW may forward the indication to the GANC, or the GANC may determine the user-type information internally or retrieve it from a database.

The present invention relates to a method for allocating service area identifiers (SAI) for a femto cell (200A) upon the femto cell (200A) being created. According to the method, information is received about detected cells obtained by scanning performed by a femto radio base station (210A) that is serving the femto cell (200A) in addition to information identifying the femto base station (210A) or the femto cell (200A); a request for SAIs, is transmitted to a SAI selection entity (250, 400) based on the received information, and SAIs selected by a selection entity (250) are received together with an associated user type. The identifiers are further allocated for the created femto cell (200A). The present invention also relates to an apparatus (100, 300) and to the selection entity (250, 400).
摘要:
An unlicensed-radio access network connects a mobile station to a conventional cellular core network. The unlicensed-radio access network includes an access controller (30) connected to the core network portion and a plurality of access points (20) connected to the access controller via a broadband packet-switched network. Each access point supports an unlicensed-radio interface permitting communication between mobile stations (10) and the access controller. Both the mobile station and the access controller comprises a first link control module (15, 35) for relaying or generating packet service frames and a second transport protocol module (13, 33). In accordance with the present invention a third, link control module (14, 34) is arranged between the first and second modules for receiving packet service frames from the first link control module, determining a transmission priority assigned to each packet frame and forwarding the packet service frames to the first transport protocol module in an order corresponding to the assigned transmission priority.
摘要:
A radio access network (24) comprises a radio network control node (26); a database (40); and a femto radio base station node (28f) serving a femtocell (Cf) of the radio access network. The femto radio base station node (28f) comprises a receiver (54) for receiving scanned cell information broadcast for one or more receivable cells of the radio access network, and a reporting unit (60). The reporting unit (60) provides the scanned cell information for the one or more receivable cells of the radio access network to the radio network control node (26). The radio network control node (60) is arranged, upon receipt of the scanned cell information, for providing configuration information to the femto radio base station node (for configuring the femto radio base station node) and for storing macro cell information for one or more receivable cells in the database (40). The macrocell information is stored in the database (40) in association with the femto radio base station node.
摘要:
Methods and apparatus provide paging control to a femto radio base station (28fj) of a radio access network (24). Paging to a femto radio base station (28fj) is controlled by maintaining a paging control database (46) of allowed user equipment units for which paging is permitted in a cell of a femto radio base station (28fj). The paging control database (46) is used to determine if a paging message for a target user equipment unit is to be forwarded to the femto radio base station. The database (46) thus serves to redefine the effective paging area by preferably including in the effective paging area only those femto radio base station for which the target user equipment unit is listed as a paging-allowed user equipment unit.
摘要:
The present invention provides a method, system and apparatus for providing security in an unlicensed mobile access network or a generic access network by receiving a message containing a mobile identity of a mobile station (MS) and dropping or rejecting the message whenever the received mobile identity does not match a stored mobile identity associated with the MS. The message is processed whenever the received mobile identity matches the stored mobile identity associated with the MS. The stored mobile identity is provided by a secure gateway. The mobile identity can be an International Mobile Subscriber Identity, Temporary Mobile Subscriber Identity, Packet Temporary Mobile Subscriber Identity, private Internet Protocol (IP) address or public IP address. The message can be a registration request, uplink message or a downlink message, such as a Mobility Management message, a General Packet Radio Service Mobility Management message, or a UMA or Unlicensed Radio Resources message.
