Definitions
- the present invention relates to mobile radiotelephony networks. It also relates to telephone devices made available to the public, also called public telephones or payphones, which are conventionally connected to the public telephone switching network.
- the current mobile radiotelephony networks whatever their nature: GSM, CDMA, TDMA, AMPS, D-AMPS or PCS, were initially designed to ensure telecommunications between users and were therefore more particularly developed to transmit the voice.
- GSM Global System for Mobile Communications
- CDMA Code Division Multiple Access
- TDMA Time Division Multiple Access
- AMPS digital signal processing unit
- D-AMPS D-AMPS
- PCS personal area network
- GSM mobile radiotelephones do not exceed the speed of 9.6 kbits / second whereas a connection by the public telephone switching network via a computer and a modem can reach 56.6 kbits / second.
- the solution currently being studied by mobile radio operators consists in increasing both the density of the network, and in particular that of its radio subsystem which provides via relays that are base stations and controllers the geographic coverage of a given area, and modify the technology used to increase performance, particularly in terms of information throughput.
- This increase in the density and performance of mobile radio networks requires heavy financial investments both in terms of technology and infrastructure.
- the installation for example, of a new base station presupposes the purchase or rental of an appropriate location, the actual installation of the base station and its connection to the rest of the network and in particular to its associated controller .
- GPRS General Packet for Radio Services
- EGPRS Enhanced General Packet for Radio Services
- UMTS Universal Mobile Telecommunication System
- the present invention therefore aims to increase the performance of a mobile radiotelephony network in terms of availability and speed of the information transmitted and this, without causing significant additional cost, through the use of the public telephone switching network and in particular payphones which are connected to it.
- the present invention therefore relates to a mobile radio network.
- this network is characterized in that it comprises: - a radio subsystem and a management and routing subsystem;
- the radio subsystem comprising at least a first mesh and a second mesh of base stations as well as the associated base station controllers;
- the base stations of the second mesh communicating with the associated base station controllers via the public telephone switching network.
- the base stations of the second mesh are located in or in the immediate vicinity of a network of devices connected to the public telephone switching network and this, in particular in order to take advantage existing infrastructure and limit installation costs.
- these devices are payphones whose number and geographic distribution are particularly well suited to the development of a mobile radiotelephony network.
- the base stations of the second mesh are connected to the public telephone switching network by means of broadband modems.
- the controllers associated with the base stations of the second mesh communicate with the sub- management and routing system via the public telephone switching network.
- the controllers associated with the base stations of the second mesh are connected to the public telephone switching network by means of broadband modems.
- the base stations of the second mesh cooperate with a plurality of communication interfaces allowing different mobile stations to access the public telephone switching network. This makes it possible to offer new services to users of mobile radio networks without necessarily having to use new communication technologies.
- the present invention also relates to a payphone of the type comprising a terminal connected to the public telephone switching network.
- the payphone according to the present invention is characterized in that it also comprises a base station of a mobile radio network, this base station being connected to the rest of the mobile radio network by means of the public telephone switching network .
- the base station is connected to the public telephone switching network by means of a broadband modem. According to another characteristic of the public telephone object of the present invention, the base station cooperates with a plurality of communication interfaces allowing different mobile stations to access the public telephone switching network.
- FIG. 1 is a principle view of the architecture of a mobile telephone system known to date
- FIG. 2 is a view similar to FIG. 1, showing an example of architecture of the extended mobile telephone network object of the present invention
- FIG. 3 is a schematic view of the functionalities of a base station integrated into the extended mobile telephone network according to a particular embodiment of the present invention.
- This architecture which is for example that of a GSM network but also that of CDMA, TDMA, AMPS, D-AMPS or even PCS networks, makes it possible to ensure digital communications between mobile telephones and between mobile telephones and sets landlines of the Public Switching Telephone Network (PSTN).
- PSTN Public Switching Telephone Network
- This standard PLMN mobile architecture consists of PT (mobile station) radiotelephones, Base Station System (BSS) radio subsystems, and Network and Switching Sub-system (NSS) management and routing subsystems .
- PT mobile station
- BSS Base Station System
- NSS Network and Switching Sub-system
- a BSS radio subsystem is a piece of equipment which covers a specific geographical area. This BSS radio subsystem provides a control function using BSC (Base Station Controller) controllers and a radio transmission function supported by BTS (Base Transceiver Station) base stations. Each BTS base station covers a territory called a cell. This manages the connections with PT mobile phones using a interface called radio interface.
- the BTS base stations are directly connected to BSC base station controllers, by wired site or by radio.
- the communications between a BTS base station and its BSC base station controller are defined by an interface called the Abis interface. Communication between the BSC base station controllers and the NSS management and routing subsystem is also done by wired own site or by radio, using an interface called interface A.
- the sub -NSS management and routing system is mainly composed of a set of elements hereinafter called MSC, HLR and VLR.
- the MSC (Mobile Service Switching Center) elements are switching centers for the mobile radio service responsible for routing communications from and to PT mobile phones as well as to the public telephone switching network PSTN.
- Each MSC element is connected by interfaces A to a set of BSC base station controllers as well as to the other MSC elements of the network.
- Each MSC element is also connected to HLR and VLR elements.
- HLR elements are databases where subscriber parameters are saved; they also contain information for each PT telephone to locate it, which is updated permanently.
- the VLR elements are databases where the fine locations of PT mobile telephones in the call area are recorded.
- the structure of the PLMN mobile telephone networks is therefore cellular, its capacity is obtained by meshing the territory using cells each served by a base station.
- FIG. 2 there is shown an extended mobile telephone network XPLMN (Extended Public Land Network) according to the present invention.
- This network consists of MS mobile stations (Mobile Station), XBSS extended radio subsystems and ENSS management and routing subsystems.
- mobile station MS physical equipment which is used by a user who travels through the geographical area covered by the XPLMN network.
- This mobile station may be a mobile radiotelephone terminal but also: a laptop or an electronic diary communicating by infrared link, a VT (Vending Terminal) vending machine accepting payments by telephone calls using Blue Tooth technology, an audio player at MP3 format suitable for downloading music programs via infrared link, etc.
- the XBSS extended radio subsystem includes two sets or meshes of base stations.
- the first mesh referenced EBSS consists of a network of BTS base stations in every respect similar to those used in the BSS radio subsystems illustrated in FIG. 1. These BTS base stations are distributed so as to provide coverage of the entire geographic territory corresponding to the network.
- the BTS base stations are conventionally connected to their associated BSC base station controllers by Abis interfaces, BSC base station controllers which are in turn connected to the ENSS management and routing subsystem by interfaces A.
- This first mesh can therefore perfectly consist of the radio subsystem of an existing mobile radiotelephony network.
- the second PBSS mesh is made up of XBTS base stations.
- the XBTS base stations are designed using a technology that is completely similar to that of the base stations of the first EBSS mesh. According to a particularly interesting embodiment of the invention these XBTS base stations are located at the level of PP payphones (PayPhone) also called telephone booths.
- PayPhone PP payphones
- Public telephones are standard terminals of the public telephone switching network PSTN which can be temporarily used by a user to communicate with a called subscriber, it being understood that said user must fulfill a certain number of obligations concerning the payment of the call.
- XBTS base stations can be done in various ways. Either they are directly integrated into the terminals of payphones which are then specially designed to allow this integration, or they are arranged outside of the latter.
- the essential point is, in accordance with one aspect of the invention, that each of these XBTS base stations is connected to a corresponding XBTS base station controller via the public telephone switching network PSTN.
- the interface between the XBTS base stations and the XBSC base station controllers is of the Abis type, the link being ensured via the PSTN network by means of high speed modems not shown of the HDSL, DSL type, the band of frequencies 0 - 4 kHz remaining allocated for the use of payphones.
- the XBSC base station controllers are connected to the MSC switching centers for the mobile radio service of the ENSS management and routing subsystem, either directly by conventional A interfaces, or even by the public telephone switching network PSTN by via broadband modems not shown, such as HDSL, DSL, ...
- the mobile station user is able to benefit from a very high capacity network and be able to access a wide choice of service. Indeed, it benefits in particular when it comes to calling performance of a very dense mobile telephone network, but also by approaching an XBTS base station, benefit from additional services, as detailed below with reference to Figure 3.
- the use of payphones to receive XBTS stations has many advantages and in particular to make the location of XBTS stations easily identifiable for users, particularly with regard to the use of additional services. It also allows for particularly easy installation and connection to the PSTN network.
- the density of payphones coincides particularly well with the density of the population and its movements or centers of interest, this results in a sizing particularly suited to the needs of users and therefore a low risk of seeing the network saturated.
- the XBTS substations into payphones, it is possible to ensure deployment of the XBSS subsystem at a relatively low cost since the infrastructures relating to payphones already exist.
- the PSTN network offers low service costs, it is possible to reduce the operator costs of the XPLMN extended mobile radio network.
- these XBTS base stations can be located in places other than public payphones, the only constraint being the need to connect the XBTS stations to the PSTN network.
- FIG. 3 there is shown schematically the new features offered to the user by the use of XBTS base station connected to the PSTN network.
- the XBTS base station is integrated into a PP public phone.
- the base station is connected to the PSTN network via a high-speed modem, for example using ADSL (Asymmetrical Digital Suscriber Line) technology which distributes frequencies between the Internet and the telephone.
- ADSL Asymmetrical Digital Suscriber Line
- other high speed modem technologies can be used such as ISDN, DSL, etc. , so as to increase bandwidth and throughput.
- the XBTS base station is configured, in particular by means of a battery of interfaces, to operate with a wide range of radiotelephone communication protocols such as GSM, CDMA, TDMA, AMPS, etc. so that it can be used by different mobile radio networks.
- the XBTS base station could only be configured to operate according to a communication protocol, that used by the network, for example GSM.
- the XBTS base station is configured to accept communications of smaller amplitudes such as those using the DECT, BlueTooth or infrared protocols. Obviously again this arrangement is not limiting of the present invention.
- the PP public phone is able to offer a whole range of services.
- the first service provided is the classic payphone which remains unchanged. Then, there is the base station service for mobile phones in the XPLMN network, this service strengthens the mesh of the network cells and therefore offers better capacity for processing incoming and outgoing calls, even if the number of users is large. since the size of the cells of the network happens to be considerably reduced.
- Another possible service consists, by means of an MP3 audio player device, of downloading an infrared recording in MP3 format from the Internet via the public phone.
- VT vending Machine
- the VT machine then communicates the amount to be debited to its server via the public phone using a Blue Tooth link.
- This VT machine therefore does not require a fixed link with the PSTN network and can therefore be easily installed and moved in the environment of the PP public phone.
- This PP public phone can also be used to communicate between a FLTS (Fixed line Telephone Service) building equipped with a local radiotelephony installation and the public switching network PSTN. The connection between this radiotelephony installation and the PSTN network is then ensured by the public phone.
- FLTS Fixed line Telephone Service
- the density and therefore the quality of this mobile radio network are greatly increased, with relatively higher infrastructure costs. low since existing sites are used and the links between these base stations and the rest of the elements of the network are made through the PSTN network.
- the density of the network is increased where the XPLMN network is is in high demand, that is to say in highly urbanized or very busy areas such as stations since these areas have a high rate of equipment in payphones.
- the use of the PSTN network to link the XBTS base stations to the XBSC controllers allows better management of the latter and easier installation.
