Abstract: In a PCM exchange a compact construction of the crossing points in a gate matrix for space interchanges is achieved by dividing each time slot of the PCM time division multiplex system into an address phase followed by a PCM phase and by transmitting in each address phase two addresses to each crossing point. Each crossing point includes a file gate and is defined by one of files forming a file side on which the PCM words during the PCM phases are incoming to the matrix and by one of files forming a file side on which the PCM words are outgoing from the matrix. One of the two addresses is transmitted on the one file associated with the crossing point and associated with the one file side to indicate one of the files belonging to the other file side. The other of the two addresses is transmitted on said other file associated with the crossing point to indicate the other file. During each address phase, an address comparison is carried out in each crossing point and if both addresses are identical an activation signal is supplied during the associated PCM phase to the file gate associated with the crossing point. The activated file gate connects the files defining the crossing point. No extra control lines and connection pins are needed for operating the file gates and therefore the above-mentioned compact construction of the gate matrix is achieved.

Abstract: Apparatus (52), and an associated method, for adaptively selecting (92) a paging area throughout which to page a mobile terminal. A record (72) is maintained, indicative of the position where a mobile terminal was located when last-accessing the network infrastructure of a communication system in which the mobile terminal is operable. When a page is to be broadcast to the mobile terminal, the record (72) is accessed, and the paging area throughout which the page is broadcast is adaptively selected responsive thereto.

Abstract: In a radio communication system including at least one radio base station and at least two telephones connected to a radio terminal, simultaneous multiple calls may be set up between the radio base station and the radio terminal. An adaptor connects the telephones to the radio terminal that is connected over a radio air-interface to the radio base station. For an outgoing call originating from one of the telephones, the adaptor senses when a particular telephone goes off-hook and signals this information to the radio base station via the radio terminal and a control channel of the radio air-interface. Then, a first traffic channel is set up between the radio base station and the radio terminal. The telephone that has gone off-hook is connected to the established traffic channel via an adaptor. Once a first traffic channel is established for a first call, signalling that a second call is to be set up may be transmitted across the first traffic channel without terminating the first call. The second call is then set up on a different traffic channel.

Abstract: The present invention teaches a method, system, terminals and service node for geographically positioning a first mobile radio terminal (MS1) within a radio network (100) comprising unsynchronised radio base stations by using a plurality of second fixed radio terminals (MS2) whereby the positions of the radio base stations and the second fixed radio terminals are known. First and second radio terminals (MS1, MS2) measure the relative receive times between the timing signals downlink (113-118) received from at least three radio base stations (BS1, BS2, BS3) and the second fixed radio terminals (MS2) send them to a service node (107) in the network (100) using them for calculating the transmission time offsets of the timing signals downlink. Calculating the position of the first mobile radio terminal (MS1) is performed either in the service node (107) in the network (100) or in the terminal (MS1) itself, after respectively sending relative receive time measurements from the first mobile radio terminal (MS1) to the service node (107), or broadcasting transmission time offset values and known positions from the service node (107) to the first radio terminal (MS1) to be positioned.

Abstract: The present invention is directed to a cellular mobile radio telephone system in which mobile stations may select either analog or digital control channels. Analog and dual-mode mobile stations are equipped to become multi-mode mobile stations which monitor both analog and digital control channels depending on the selected mode. Downlink multi-mode mobile stations, while required to use analog control channels for call access, may nonetheless scan digital control and paging channels to receive downlink control and paging communications from the land-based system. Bi- directional multi-mode mobile stations have the same capabilities as downlink mobiles but also are equipped to transmit control information to the land station over the uplink digital control channel. If no digital control channel is available, the multi-mode mobile stations scan primary and secondary sets of analog control channels. In this way, analog and dual-mode mobile stations may benefit from the advantages of monitoring digital control channels and digital paging channels including multiple pages per channel and battery-saving capabilities.

Abstract: A method and apparatus for reestablishing a call after a call has been disconnected or after the quality of the call has become bad is disclosed. A disconnected mobile station scans the signal strength of surrounding base stations and accesses the base station with the highest signal strength. The mobile station then initiates a new call back to a service node. The base station then assigns the mobile station a traffic channel and the service node reconnects the call. In addition, a method for reestablishing a call in any communication network after the call has been terminated in a normal fashion is disclosed.

Abstract: A mobile telephone system has in a cell (C1) a base station (BS1) and sub-stations (MT1, MT2, MT3) which are connected to a mobile switching central (MSC) by means of cables (2). The mobile telephone system has control channels (CC) and frequencies which are time divided to traffic channels. Some of the frequencies are selected as identification frequencies. Each of the sub-stations (MT1, MT2, MT3) is assigned a unique set of frequencies from among the identification frequencies and constantly transmit their respective frequency set. A mobile station (MS) connected to the base station (BS1) listens to the identification frequencies and reports the strongest of these frequencies to the mobile switching central (MSC). The mobile switching central compares the reported frequencies with the unique set of frequencies, compares the reported signal strength with a threshold value and selects the nearest sub-station (MT2) for handoff. The mobile switching central (MSC) switches from the base station (BS1) to a connection (4) with the sub-station (MT2). The mobile station (MS) continues to listen to the identification frequencies and reports the signal strength on its connection (4). When the strength of the signals from the selected sub-station (MT2) is low, the connection (4) is switched back to the base station (BS1).

Abstract: A mobile telephone system with two home location register units mirroring each other is disclosed. In the event of a crash in one unit a backup copy is first loaded. Thereafter, records in the loaded backup copy that have changed after the latest position dump before the crash are updated with information from the other home location register unit, the mirror copy of which is updated after the position dump.
