摘要:
In a mobile communications network including an unlicensed radio access portion adapted to communicate with mobile stations over an unlicensed-radio interface an arrangement and method is proposed to permit calls to be handled differently depending on whether the caller and subscriber wishes to connect via the unlicensed radio access network or not. This is achieved by providing a home location register adapted to identify stored subscriber identity information identifying a mobile station from at least two separate dialled numbers and to output mobile station location information associated with the subscriber identity information in response to the dialled number. At least one of these numbers is reserved for connections to a mobile station via the unlicensed radio access network portion only. The mobile communications core network is furthermore arranged to terminate a call using the second dialled number when a mobile station is not connected to the unlicensed radio access network.

An end node in a packet-switched network is proposed wherein the end node is arranged to exchange packets consisting of a packet header and payload data with a server node connected to the packet-switched network. The end node includes at least one module adapted to extract quality of service parameter values from the headers of packets received over the packet-switched network and to insert the extracted quality of service parameter value in the headers of packets destined for transmission to the server node over the packet-switched network. In this manner the end node automatically adapts the quality of service parameters received over the packet-switched network to correspond with the type of quality of service defined in received packets. Such a system means that only the server node need be configured with the quality of service parameters applicable on the particular packet switched network, so greatly reducing the installation and configuration overheads in a multi-user network.

An unlicensed-radio access network is proposed for communication with a mobile terminal and packet service nodes in a core network portion of a mobile telecommunications network. The access network comprises local base stations each defining a mini-cell and adapted to communicate with mobile terminals over an unlicensed-radio interface and an access network controller connected to the local base stations and to a packet service node in the core network portion. The mini-cells are also grouped into at least two packet service cells. The local base stations that generate these mini-cells are assigned a cell identifier comprising a first identifier portion that is common for all local base stations connected to the access network controller and a second identifier portion that is different for local base stations in different packet service cells but common for all local base stations in the same packet service cell.

A method and a radio node (RN) shared by operators of separate cellular networks having operator specific tracking area plans. The radio node (RN) broadcasts (1:1) system information with network identities of the cellular networks (PLMN IDs) and multiple operator specific tracking area codes (TACs) valid in respective tracking area plans of the cellular networks, each tracking area code being associated with a corresponding network identity in the system information. Thereby, the operators are enabled to use their own operator specific tracking area codes for their respective operator specific tracking areas that include a cell (100) covered by the radio node.

Methods and systems described herein may provide for the updating, maintenance, and/or transference of a CSG White List that is stored on a user equipment. The CSG White List may be implemented to store information related to the access of CSG cells, such as, for example, femto cells. Additionally, methods and systems described herein may provide for the updating, maintenance, and/or transference of an access control database. The access control database may be stored in one or multiple devices in a communication system. The access control database may be implemented to store information regarding home nodes and which user equipment is allowed to access the femto cell or CSG cell provided by each home node.

The invention relates to handover of a mobile station (12) from a source cell to a target cell when the identity of the target cell in a wireless communication network (10, 11) is ambiguous, a source base station (14) defining the source cell receives an event from the mobile station comprising a cell identifier, investigates if there are more cells in the neighborhood sharing the same cell identifier and sends a handover instruction to the mobile station comprising an identity ambiguity indicator if there are more cells sharing the same cell identifier. The mobile station autonomously initiates establishment of a connection to a target base station defining the target cell based on the identity ambiguity indicator in order to effect handover.
摘要:
A telecommunication system and method for controlling the establishment of payload connections through media gateways. The system receives and aggregates control orders from a plurality of telecommunication nodes such as media gateway controllers. The system uses knowledge of resources in the network to optimize the path of the payload connection. The system also sends control orders to a given media gateway in order to establish the payload connection. The system may be connected to a plurality of other instances of the same type of system in a hierarchical manner.

The present invention relates to a method and a network control node for tracing activity and monitoring performance of user equipments in a partly IP-based wireless communications network. The wireless communications network comprises operator controllable and/or operator uncontrollable wireless access points in communication with a network control node via one or more operator controllable and/or operator uncontrollable Internet Protocol, IP, networks. The described method is characterized by a first step of receiving a trace triggering request and user equipment identification, at a network control node, from a first network node. Alternatively, the trace triggering request is received on a signaling connection that explicitly identifies the user equipment. The network control node then starts a trace recording and information retrieval procedure relating to the identified user equipment and identifies all used IP networks and user equipment serving access point. The method further comprises the steps of analyzing the IP networks used between the network node and the user equipment and/or analyzing the user equipment serving access point. Thereafter, a trace printout is created including analyzing results and retrieved information, the printout is to be sent to a second network node, or stored locally for later retrieval.

A first and a second base station, and respective methods therein are provided for enabling communication between the first base station and the second base station, wherein one of the base stations enables the other base station to obtain synchronization information. One of the base stations has information of a time server it is using for obtaining synchronization information. When one of the base stations detects the presence of the other, this time server information is sent to the base station not having the time server information, thereby enabling this base station to obtain synchronization information from the same time server as its counterpart.
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.
