  • GSM Global System for Mobile Communications
  • a plurality of different commercial networks provide to a user alternative choices of access to what can be considered in general terms an overall cellular communications systems.
  • the different networks may share hardware or may each have separate hardware such as BTSs.
  • the means by which a user selects a network is predetermined to select a particular network, provided the radio signal offered by that network meets a certain minimum standard. Only if that signal fails to meet that standard, are other networks considered for selection. Even when roaming such that the users primary network choice is not available, networks are chosen merely on signal strength or some other simple criteria basis.
  • the Universal Mobile Telecommunication System currently under standardisation is intended to provide a harmonised standard under which cellular radio communications networks and systems will provide enhanced levels of interfacing and compatibility with other types of communications systems, which in addition to speech and data services, will further include extensive provision for multi-media communications. It is also expected that within the framework of developments such as UMTS or the like, cellular radio communication systems will play an increasing role in information highways such as the internet.
  • the present inventors have envisaged that it will be desirable to optimise the basis on which a user selects a network in a communications system.
  • the present inventors have envisaged that known ways of selecting a network in a cellular communications system will be undesirable for the case, in systems such as UMTS, where the network is to be used merely as one part of an overall communications route, which overall communications route will comprise also a further communications element such as a landline telecommunications link, and moreover where the communications link is to be used to convey a service from a separate service provider.
  • the present inventors have envisaged that overall considerations involving the cellular network's relationships with the further communication link and the service provider might be more significant to the benefit to the user when choosing the cellular network part of the overall link.

  • the resource under consideration is financial cost
  • the user will be able to select that network which will provide the lowest overall cost of the service being provided from the service provider to the user via the overall communications route. This is advantageous over consideration of just the direct costs of the network per se. Similar advantages occur for other resource types, for example power required.
  • a preferred version of the present invention enables the user to vary which type of resource is to be considered. So for example, in the case where the user can vary between cost and power, the user can decide to usually select a network based on cost, but when his power supply is low can instead decide to select according to power usage.

  • the radio link between user terminal 112 and second network 130 is shown as item 114 in Fig. 1.
  • the first network and the second network are each made up of separate hardware such as base station systems, switches, radio transceivers and so on. Also they are separate in a commercial sense.

  • the different networks could share some or all of their hardware, but constitute nevertheless different networks by virtue of being managed by different commercial entities on a time division basis or with respect to access to different radio channels and so on, and these networks may themselves be hiring such air-time or channels from different commercial entities using the relevant hardware.

  • the resource query identifies the service, i.e. an international call to a given number, the call requiring multi-media facilities in the sense of live video communication plus data transfer capability.
  • the user identifies the service provider, in this case service provider 140, who represents a supplier of international calls chosen by the user.

  • the next step is that of the networks 120 and 130 communicating with service provider 140, via communications links 126 and 136 respectively, to acquire service provider resource functions applicable to delivery of said service with respect to the further communications elements 150 and 160 which represent the candidate further communications elements of the present embodiment, being for example the only two international telephone services to the country of the number called.
  • each request service provider 140 to inform them of any special pricing arrangements, such as discounts, appropriate tariffs, available capacity already paid for, and so on, pre that service provider 140 has in place with each of the further communications elements 150 and 152 respectively.

In the present embodiment the databases are located in central operation centres of the respective networks, but they can also be located at any other appropriate location accessible to a networks, including being distributed throughout a number of separate locations.
  • a further step is that of the networks 120 and 130 determining a respective network resource function applicable to that network for delivery of services generally with respect to the further communications elements 150 and 160.
  • first network 120 the pricing structure information necessary for such determination relevant to general services transmitted from, for example, first network 120 via first further communications element 150 will already be known at first network 120, and this information will also be held in database 128.
  • this information was not held already, it could be gained by communication between the network and the further communications element via the appropriate communications link.
  • the pricing information already held at the database is put in an appropriate form compatible with the form of the received service provider resource functions, thereby providing, for each network, a network resource function covering each of the candidate further communications elements.
  • each network at this stage of the procedure holds in its database respective service provider functions and respective network resource functions, in compatible formats for cross-referencing and optimising.
  • each network by using appropriate processing means and algorithms, can now analyse the different pricing structures, discounts etc. available, and in doing so include either or both the benefits available from the network's relationship with the different further communications elements and the service provider's relationship with the different further communications elements, to arrive at the best overall cost that the network can offer the user if the user selects that network.
  • This is implemented by the step of the networks calculating a respective overall resource function from the service provider resource functions and the respective network resource function.
  • the respective overall resource function is simply in the form of the cheapest total cost for the call.

This can be determined by the user of the user terminal in the case when the values are displayed. Alternatively, the optimum overall resource function can be determined automatically by processing means within the user terminal.
  • the next step is that of the user selecting whichever network has transmitted the optimum overall resource function. This can also be carried out manually by the user, or in the case when the optimum overall resource function has been determined automatically in the user terminal, can be performed automatically also.
  • a second embodiment is implemented in corresponding fashion to the first embodiment except that the resource to be considered is power used by the user.
  • the primary concern is power consumption.
  • This situation could arise for example when the user terminal is a mobile telephone, for the purpose of minimising consumption of power from a battery of the mobile.
