Abstract: The invention concerns methods, a device and computer program products for simplifying handover back to a restricted local access point from an unrestricted global access point as well as to a device implementing a restricted local access point for provision in a wireless network and a wireless network. In the network a restricted local access point hands over a mobile station to an unrestricted global access point and provides data enabling the restricted local access point to be identified as a candidate access point. A device for simplifying handover back determines that the restricted local access point is a candidate for further handover based on this data and informs the mobile station about the restricted local access point via the unrestricted glob access point. Thereby hand over may be considered also to the restricted local access point in addition to other surrounding access points.

Abstract: 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.

Abstract: The present invention relates to methods and arrangements in mobile radio telecommunications for enabling access to Circuit Switched (CS) services for a user equipment (UE) that is connected to a LTE/SAE (Long Term Evolution/System Architecture Evolution) network. The UE's current position is stored in a LTE position format in the LTE network or in the SAE network. The invention provides steps and means for transforming the UE's position in LTE format to position information in CS format for the UE, steps and means for registering the UE in the CS network using said transformed position information, and steps and means for establishing access to CS services provided by said CS network.

Abstract: The present invention relates to a network node arrangement comprising a server node adapted to handle control signaling for circuit switched calls and being connected to a gateway node adapted to handle user plane traffic under control of said server node, said server node further being adapted to control connections between mobile stations over a radio network. The server node is adapted to, for a first and second call leg of a requested call connection between a first mobile station and a second mobile station, provide information to the gateway node about radio network node handling the first call leg and the second call leg and circuit information about circuit resources for said first and second call legs.

Abstract: In cellular mobile networks handover between base stations of adjacent cells requires the identity, address and frequency of all adjacent cells to be known to other elements of the network. Conventional networks can be extended by the addition of unlicensed-radio access networks. These include an access network controller (303) preferably connected via a broadband network (302) to a plurality of low-power local base stations (301), which communicate with mobile stations (1) over an unlicensed radio interface. The number and changing location of the local base station renders the operation and maintenance required to enable handover from the conventional network to these access networks prohibitively complex. This difficulty is alleviated by assigning the whole access network a single identifier. With this arrangement regardless of which base station mini-cell (304) an active call is being handed-over to, the conventional network will be able to route the request to the access network controller.

Abstract: A method ensures that a reduction in data throughput is minimized in the event of a cell change in a GPRS network. When it is determined that cell change is appropriate for a mobile station, the BSS ensures that no further data for the mobile station is transmitted form the SGSN, and then continues to transmit all buffered data to the mobile station. The throughput may be deliberately reduced for a part of this time, so that the system timers become adapted to the reduction in throughput which will occur at the cell change. When the buffer has been emptied, the cell change is effected and, thereafter, that mobile station is prioritised in the BSS, in order to allow any buffered data on the uplink or downlink to be cleared.
