摘要:
A system, method, and User Equipment, UE, for providing a current LTE cell location to a Generic Radio Access Network Controller, GANG, based on different triggers depending on the UE state. The GANC ensures that the correct GANG is serving the UE, and also maps the LTE cell location to an associated GAN Cell Global Identifier, GAN-CGI. The GANG provides the GAN-CGI to a Mobile Switching Center, MSC, or other serving core network node to support location-based services and other mobile originated or mobile terminated calls and transactions.
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.

摘要:
Cellular mobile networks can include unlicensed-radio access networks, which comprise access point controllers connected via a fixed broadband network to access points that communicate with mobile stations via unlicensed radio. The access points are connected to the broadband network from any location by the subscriber. In order to alleviate the configuration required to enable handover each access point controller is assigned to a location area defined in the conventional cellular network. A mobile station entering the mini-cell of an access point sends the access point information concerning the location area for the last cell of conventional network it communicated with. With this information, the access point obtains from a memory the fixed broadband address of the access point controller assigned to this location area. The access point uses this address to establish a connection with the access point controller assigned to handle its current location.
摘要:
A method and radio network controller (RNC) in a radio access network (RAN) for controlling access to a cellular telecommunication system. Upon receiving an access request from a given user equipment (UE) through a given radio base station (RBS), the RNC retrieves authorization information from an access control database within the RAN. The authorization information indicates whether the given UE is authorized to access the system through the given RBS. The RNC alternatively grants access or denies access to the UE based on the retrieved authorization information. The RBS is particularly useful for controlling access through small cells with limited capacity.
摘要:
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 device associated with a transport network generates a first traceroute through the transport network, and monitors a performance measure associated with the transport network. The device also compares the performance measure to a criterion, and determines degradation in the transport network when the performance measure matches the criterion. The device further generates a second traceroute through the transport network when the degradation occurs in the transport network, where the first and second traceroutes are used to determine a source of the degradation in the transport network.
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.
摘要:
A system, method, and arrangement for controlling access to a wireless communication network. When a User Equipment (UE) is denied access to the network through a first access point, the UE stores the Location Area Identity (LAI) utilized at the first access point on a list of forbidden LAIs in the UE. If the LAI stored by the UE is utilized at another access point where the UE is allowed access, the LAI at the other access point is dynamically changed to a second LAI that is not on the UE's list of forbidden LAIs. An access point database stores a table defining which UEs are allowed to utilize each access point. The database also stores a list of rejected LAIs for each UE. A radio network controller accesses the database to determine an allowed LAI, and changes the LAI at the other access points where the UE is allowed access.
摘要:
A method for a cellular network (100) comprising cells (110) of a first kind controlled by corresponding base stations (111), and cells (120-122) of a second kind controlled by corresponding base stations (125-127). The second kind of cells are smaller than the first kind of cells (110). The network (100) comprises functions (140) for control of the base stations, and functions (150) for handing over the control of user terminals (123, 112) between base stations. The method is used when a call in a cell of the second kind (120-122) is handed over to a base station of the first kind. The method lets said control function (140) of the base station of the cell of the second kind send identifying information to the control function (140) of the base station (111) of the first kind, such that if the call is to be handed back to the original base station (125-127), the original base station can be found by the network.
