Abstract: A system and method for directing a Gatekeeper Request Query (GRQ) message or a SIP discovery message to a preferred call control server in a General Packet Radio Service (GPRS (25, 32, 41)), Universal Mobile Telecommunication System (UMTS), or Code Division Multiple Access (CDMA) network. The network may operate with the Session Initiation Protocol (SIP) or the H.323 protocol. A mobile terminal sends the GRQ message to a Gateway GPRS Service Node (GGSN(22)) which is modified with a Server Discovery Agent (SDA(23)). The SDA includes a lookup table (55) comprising a list of preferred gatekeepers, and selects the preferred gatekeeper from the list and unicasts (26) the GRQ message to the selected preferred gatekeeper. The gatekeeper then responds to the mobile terminal. The gatekeeper may send a confirmation message to the SDA. If the SDA does not receive the confirmation message within a predetermined time period, the SDA may select another gatekeeper, or may multicast (33) the GRQ message to a plurality of gatekeepers. Alternatively, the SDA may multicast (42) the GRQ message over a predefined area which is controlled by modifying the Time-to-Live (TTL(46)) field in the header of the packets in the GRQ message.

Abstract: A method and system for improving the quality of service for data transmission to a mobile station (10). In accordance with one embodiment of the invention, a candidate cell (38(2)) for handoff of the mobile station is identified in response to the detection of a need to perform a handoff. Buffering resources for use in connection with the data transmissions are then allocated (82) in the candidate cell. In accordance with another embodiment, a condition causing a potential reduction in the quality of service to the mobile station is detected, and in response thereto, an existing allocation of buffering resources in the system is increased (56) to compensate for the potential reduction in the quality of service. In accordance with yet another embodiment of the invention, a condition causing a potential reduction in the quality of service to the mobile station is detected. In response thereto, a transmission rate of data to the mobile station is increased (116) to compensate for the potential reduction in the quality of service.

Abstract: A method and system for responding to a trigger condition detected during the handling of a call connection in an intelligent network (IN). Upon receipt of an IN trigger, a service interaction manager (40) in a service control point (14) queries (37) a home location register (60) for a subscriber involved in the call connection requesting subscriber subscription information. The service interaction manager also queries (95) a service library (50) associated with the service control point to determine which of an implicated set of services are currently available in the service library and what the properties of those services are. Depending upon which services are available, which services are in the subscriber's subscription list, and the service priority information received from the home location register and the service library, including the properties data from the service library, the service interaction manager reduces the list of implicated services to an applicable set of services and generates a customized execution sequence for the applicable services. Thereafter, at least one of the applicable services is executed (108) in accordance with the customized execution sequence.

Abstract: A system and method in a packet-switched radio access network of sending data packets over a radio interface from a Mobile Station (MS) to a Radio Network Controller (RNC) using multiple data transmission paths. When the MS launches a new application through a first base station (BS1), a Multi-path Context Activator (MCA) in the RNC determines whether the bandwidth required by the new application exceeds the bandwidth capacity of the radio interface portion of the first data transmission path. If so, the RNC identifies a second BS (BS2) that has the capacity to provide a portion of the radio interface bandwidth required. The MS then transmits separate data streams to BS1 and BS2 over the radio interface. The MCA combines the separate upstream data portions. For downstream packets, the MCA separates the packets into two streams sent to an MCA and to the MS via BS1 and BS2.

The network node is arranged to transmit a discovery reference signal, DRS, comprising a first and a second synchronization signal for enabling the wireless devices to find and measure the cell, and wherein the DRS, when the network node operates a primary cell in the unlicensed frequency band, comprises system information, and additional or adapted synchronization signal for enabling the wireless devices to identify the presence of the system information and acquire further cell information. A wireless device for operating with such a network node is also disclosed. The wireless device is arranged to receive a transmission from the network node, determine synchronization signals in the transmission, and from the synchronization signals determine whether it is a discovery reference signal, DRS, comprising system information by identifying an additional or adapted synchronization signal in the transmission, and, upon determined presence of the system information, read the system information.

Abstract: A method in a radio telecommunications network of broadcasting data in an over-the-air multicast to a group of mobile terminals. Statistics from regular point-to-point cellular transmissions to build a statistical database for each base station. The statistical data indicate the optimal signal quality that users normally experience when operating in that cell. From this data, a minimum transmission quality (TQmin) that a mobile terminal must receive for the type of data being broadcast is determined. The method then broadcasts a test transmission to the mobile terminals, and includes a maximum transmission quality (TQmax) in order to limit the number of responses. A response is then received from a mobile terminal representative of the group, the response including an indication of the received transmission quality. The method then determines whether the received transmission quality was greater than or equal to TQmin. If the received transmission quality was greater than or equal to TQmin, the data is broadcast in the over-the-air multicast to the group of mobile terminals.
