摘要： A method and an arrangement for subscriber location management among a group of radio networks comprising at least two radio networks (101, PMR1, PMR2) in which at least some of the subscribers (SBR1, SBR2, SBR3) may roam away from the home network and register in another radio network over the radio path. To enable centralized subscriber location management, the subscriber database (HLR) of one radio network (101) is arranged to maintain in a centralized manner the location data of all subscribers (SBR1) that have roamed outside their home networks and registered in another radio network (PMR2) at least with an accuracy of a radio network.

摘要： The invention relates to a method for allocating control channels in a radio system comprising base stations (101) and subscriber stations (102, 103) communicating with the base station on control and traffic channels. To make the control channel operation more efficient and to avoid interference, traffic channels are allocated for control channel use so as to distribute the control channel operation between a greater number of channels, the channels allocated for control channel use being indicated to the subscriber stations (102, 103), and control channel operation is performed on the control channels allocated in a distributed manner.

摘要： L'invention concerne un procédé d'accès aléatoire pour un système de radiocommunications qui comprend plusieurs stations radio (RS1, RS2, RS3, RS4, RS5, RS6) et au moins une station de base (BS) à laquelle elles sont reliées. Avec ce procédé, la station de base (BS) émet un message d'appel (HPK) vers les stations radio (RS1-RS6) dans un premier intervalle de temps pour leur donner le droit de lui envoyer un message d'accès aléatoire (HP). Une des stations radio (RS1) émet un message d'accès aléatoire HP(S1) contenant une identification aléatoire (S1) vers la station de base (BS) dans un deuxième intervalle de temps (A1) postérieur au premier. La station de base (BS) émet un message de réponse V(S1, TT7, A1) contenant cet identificateur aléatoire (S1) vers la station radio (RS1) dans un troisième intervalle de temps (A6) postérieur au deuxième. Pour éviter la difficulté provenant de l'allocation des mêmes ressources de télécommunications à plusieurs stations radio, le message de réponse V(S1, TT7, A1), envoyé par la station de base (BS) vers cette station de radio (RS1) pendant le troisième intervalle de temps, contient l'identificateur (A1) propre au deuxième intervalle de temps.

Date May 11, 1995A method for controlling a subscriber station operating on a direct mode channel in a mobile radio system. The mobile radio system is one which includes a radio network with at least one base station and subscriber stations, and at least one subscriber database and further, at least one repeater station, which forwards traffic between the at least one base station and the subscriber stations operating on a direct mode channel. In the method, a subscriber station is registered in a radio network via a base station. The subscriber station transmits a detachment message to the base station, and indicates that it is switching to operate on a direct mode channel. In order that the radio network is able to control and communicate with the subscriber station switched to the direct mode channel, the identifier of the repeater station via which repeater station operating on the direct mode channel can be reached by the radio network, is transmitted to the radio network. The identifier of the repeater station is stored in the at least one subscriber database of the radio network.

摘要： A method for allocating emergency speech items in a mobile communication system comprising a network infrastructure (BS), a first subscriber station (MS1) connected to it, and at least one other subscriber station (MS2, MS3), the method comprising maintaining a group call consisting of speech items between the first subscriber station (MS1) and at least one other subscriber station (MS2), transmitting an emergency speech item demand (101) from the first subscriber station (MS1), which is in an emergency, to the network infrastructure (BS), and transmitting an emergency speech item grant message (102) from the network infrastructure to the first subscriber station. The method further comprises transmitting, to the at least one other subscriber station (MS2, MS3), emergency speech item information (103) containing the identifier of the first subscriber station (MS1) and indicating that an emergency speech item has been allocated (102) to the first subscriber station. In response to the emergency speech item information (103), the user of the at least one other subscriber station (MS2, MS3) is informed that an emergency speech item has been allocated (102) to the first subscriber station.

摘要： A method for establishing a connection between a first communication device (MS1), connected to a communication network and having at least one identity, and one or several second communication devices (MS2 to MS9), connected to the communication network and located in a limited location (paging) area, each of them having at least one identity. In order that the user of the system may define the location area dynamically, the first communication device (MS1) sends to the communication network a message containing an identification of the location area (Ak) and the identity of one or several second communication devices and the communication network calls at least one subscriber device (MS2 to MS9) provided with said identity only in the location area defined by said location area (Ak) identification.

摘要： A method for allocating time slots (101-104) in a mobile communication system comprising a base station (300) and mobile stations (MS), said base station communicating with said mobile stations on a radio frequency divided into TDMA frames (1-18), which are further divided into time slots (101-104), of which at least one (101, 103, 104) can be allocated as a traffic channel of one or more mobile stations. The method comprises the steps of transmitting information from the base station (300) to a mobile station (MS) on the allocation of a time slot other than a traffic time slot (101, 103, 104) used by the mobile station as a signalling time slot (102) common to the mobile stations (MS) communicating on said radio frequency, starting to use said time slot (102) as a signalling time slot common to the mobile stations (MS) communicating on said radio frequency in the signalling traffic between said base station (300) and said mobile stations in such a manner that the mobile stations can also communicate in one or more traffic time slots.

摘要： A method for synchronizing a telecommunications connection in a mobile communications system comprising at least one base station and a first and at least a second mobile station communicating on a direct mode channel. In accordance with the method, the first mobile station operating on the direct mode channel transmits a registration message to the base station of the mobile communications system on a system channel of the mobile communications system, the registration message indicating the wish of the first mobile station to operate in the dual watch mode on the control channel of the mobile communications system. In response to the registration message, a specific control channel of the base station and the timing information related to the control channel are communicated to the first mobile station, the first mobile station switches (811) to the dual watch mode in order to communicate either on the direct mode channel or on the allocated control channel during the time indicated by the timing information.
