  • a geographical region is divided into a number of cells each of which is served by base station.
  • the base stations are interconnected by a fixed network which can communicate data between the base stations.
  • a remote unit is served via a radio communication link by the base station of the cell within which the remote unit is situated.
  • a remote unit may move from the coverage of one base station to the coverage of another, i.e. from one cell to another.
  • the remote unit moves towards a new base station, it enters a region of overlapping coverage of two base stations and within this overlap region it changes to be supported by the new base station.
  • the remote unit moves further into the new cell, it continues to be supported by the new base station. This is known as cell reselection or handover.
  • the fixed network interconnecting the base stations is operable to route data between any two base stations, thereby enabling a remote unit in a cell to communicate with a mobile station in any other cell.
  • the fixed network may comprise gateway functions for interconnecting to external networks such as the Public Switched Telephone Network (PSTN), thereby allowing remote units to communicate with landline telephones and other communication terminals connected by a landline.

  • the fixed network comprises much of the functionality required for managing a conventional cellular communication network including functionality for routing data, admission control, resource allocation, subscriber billing, mobile station authentication etc.
  • Examples of cellular communication systems include both public cellular communication system such as the Global System for Mobile communication (GSM) and Professional Radio (PMR) systems such as TETRA (TErrestrial Trunked RAdio).
  • GSM Global System for Mobile communication
  • PMR Professional Radio
  • TETRA TErrestrial Trunked RAdio
  • GSM Global System for Mobile communication
  • TDMA Time Division Multiple Access
  • a base station may be allocated a single carrier or a multiple of carriers.
  • One carrier is used for a pilot signal which further contains broadcast information. This carrier is used by mobile stations for measuring of the signal level of transmissions from different base stations, and the obtained information is used for determining a suitable serving cell during initial access or handovers.
  • Further description of the GSM TDMA communication system can be found in 'The GSM System for Mobile Communications' by Michel Mouly and Marie Bernadette Pautet, Bay Foreign Language Books, 1992, ISBN 2950719007.
  • 3rd generation systems are being rolled out to further enhance the communication services provided to mobile users.
  • the most widely adopted 3rd generation communication systems are based on Code Division Multiple Access (CDMA) wherein user separation is obtained by allocating different spreading and scrambling codes to different users on the same carrier frequency.
  • CDMA Code Division Multiple Access
  • the transmissions are spread by multiplication with the allocated codes thereby causing the signal to be spread over a wide bandwidth.
  • the codes are used to de- spread the received signal thereby regenerating the original signal.
  • Each base station has a code dedicated for a pilot and broadcast signal, and as for GSM this is used for measurements of multiple cells in order to determine a serving cell.

  • TETRA may be used as a public cellular communication system but is designed to provide a number of features and services which are particularly suitable for private organisations or groups such as the emergency services.
  • TETRA provides a number of features and services for managing and controlling group calls as well as for managing the membership of these groups. Other features and services provided by TETRA include, push-to-talk channel allocation, broadcast calls etc. Also, in addition to trunked mode operation wherein remote units communicate via a base station, TETRA provides for the possibility of communication which is communicated directly between remote units. This is known as Direct Mode Operation (DMO) and allows remote units to set up and maintain direct communication between these.
  • DMO Direct Mode Operation
  • TETRA is a Time Division Multiple Access (TDMA) system wherein 25 kHz wide channels are further divided into four time slots which may be individually assignable. Each time slot has a duration of 14.167 msecs and four timeslots are combined into a time frame having a duration of 56.67 msecs. Each of the four time slots in a time frame may be individually allocated to the same or different remote units. Furthermore, the time frames are combined into multiframes comprising 18 time frames. Frame number 18 is reserved as a control frame wherein control information may be communicated during an active call.
  • TDMA Time Division Multiple Access
  • mobile stations provide a user interface, such as speakers, microphones and displays, which requires that the mobile station is suitable for use in operating positions that provides a convenient interface to the user. For example, to make a voice call a mobile phone must typically be held by the users head to provide proximity to the microphone and the speaker. Although hands free headsets have been introduced to allow that mobile phones are used in other positions, these are additions to existing mobile phones thereby further increasing the weight, size and number of items that must be carried.

  • the subscriber identity information can be transmitted from the first communication device 101 to the second communication device 103 over the short range air interface in any suitable way and at any suitable time(s).
  • the subscriber identity information may be transmitted at regular intervals, in response to inquiry messages from the second communication device 103 or when a given event occurs.
  • the first communication device 101 is operable to transmit the subscriber identity information in response to a detection of it entering an active operating state. For example, whenever the first communication device 101 is switched on, a message comprising the subscriber identity information may be transmitted to the second communication device 103.
  • more complex means of detecting an operating state may be used such as a detection of an operating position.
  • a mechanical switch may detect a physical orientation of the device and the subscriber identity information may be transmitted whenever the switch detects a change from an orientation associated with a non- active state to an orientation associated with an active state.
  • An advantage of the separation between the first communication device 101 and the second communication device 103 is that both may be reduced in size and weight. Furthermore, the separation of the subscriber identity information from the functionality for communication over the air interface allows for the second communication device 103 to be a general unit that is not specific to the individual subscriber and which may support a plurality of different subscriptions. This allows increased design freedom and in particular allows increased design freedom for the physical implementation of the communication devices. It also allows increased flexibility in the use of the communication device.

  • the communication devices may be comprised in clothing or footwear.
  • the second communication device 103 may be built into a belt buckle, a coat or a pair of boots. This will facilitate carrying of the communication device and allow for the user to always have cellular communication means with him.
  • the battery consumption associated with communicating over the cellular air interface is typically higher than for communicating over a short range air interface, the batteries and thus the size and weight of the second communication device 103 is typically larger than for the first communication device 101.
  • a large common communication unit may be carried in a convenient and unobtrusive fashion while communication unit interfacing with the user may be made smaller, lighter and suitable for operation in a convenient operating position.
  • the first communication device 101 may be comprised in headset.
  • the short range air interface may be part of an ad-hoc network such as an IEEE 802.11 ad hoc network.
  • the first communication device 101 may continually scan for other ad-hoc network devices, and if one is detected information is exchanged to determine if the new network device has functionality for communicating with a cellular communication system, i.e. whether it comprises the functionality of the second communication device 103. If so, the first communication device 101 may use the new network device to communicate over the cellular communication system.
  • This embodiment may completely remove the requirement for the user to carry any functionality for communicating on a cellular air interface. Hence, only a very small and low cost device needs to be carried.
  • the invention can be implemented in any suitable form including implementation of functionality in hardware, software, firmware or any combination of these. However, preferably, the invention is implemented partly as computer software running on one or more data processors and/or digital signal processors.
  • the elements and components of an embodiment of the invention may be physically, functionally and logically implemented in any suitable way. Indeed the functionality of each communication device may be implemented in a single unit, in a plurality of units or as part of other functional units.

Abstract

L'invention concerne un système de communication comprenant: un premier dispositif de communication (101) présentant une interface utilisateur (113); une unité d'information sur les abonnés (117) qui extraie, d'une carte SIM par exemple, des informations d'identification d'abonnés d'un système de communication cellulaire; et un émetteur-récepteur à courte portée (115). Le premier dispositif de communication (101) communique avec un second dispositif de communication (103) par une interface hertzienne de courte portée (111). Le second dispositif de communication (103) comprend également un moyen de communication par une interface hertzienne (105) du système de communication cellulaire (107, 109). Un processeur d'information sur les abonnés (121) reçoit les informations d'identification d'abonnés du premier dispositif de communication (101), et un processeur de contrôle de communications (123) exploite les informations d'identification d'abonnés pour établir une communication dans le système de communication cellulaire. Un processeur d'établissement de communication (127) étend ensuite la communication au premier dispositif de communication par l'interface hertzienne de courte portée.
