Abstract: There is described a method for operating a proxy in a network function virtualization (NFV) system. The NFV system comprises a virtualized network function (VNF) manager for managing a VNF, a virtualized infrastructure manager (VIM) for managing a resource, and a NFV orchestrator. The method comprises: receiving a resource allocation request for the VIM from the VNF manager; sending the resource allocation request to a component of the VIM; receiving a response to the resource allocation request from the component of the VIM; and sending the response to the NFV orchestrator.

Abstract: A system for providing services to subscribers of a network supports the provision of a plurality of different services to multiple subscribers. Multiple processing units are provided, each providing a respective execution environment for a respective set of software applications. A data structure is provided containing data identifying the sets of software applications or software application components of the sets of software applications, and different developers are provided with different access rights to the data in the data structure. Different software applications or software application components are associated with different access right levels. This provides a software development environment in which a common services repository is provided with different access rights implemented for accessing the repository.

Abstract: A conferencing system, method and communication device for facilitating a conference call between a plurality of terminal devices is presented. The conference system comprises: a conference server for establishing the conference call; and re-connection means adapted to detect if a terminal device is disconnected from the conference call and to re-connect a terminal device to the conference call if it is detected that the terminal device is disconnected from the conference call.

Abstract: One embodiment of a system for providing services to subscribers of a network supports the provision of a plurality of different services to multiple subscribers. A processor arrangement is provided for hosting the different services. A data structure is provided for storing data associated with subscribers of the system, wherein data associated with subscribers of the system comprises a plurality of sets of data, each set of data relating to a respective level of authentication. A trust model comprises a set of relationships between the sets of data, and the trust model determines the access rights of subscribers to different services in dependence on the data set which has been used to authenticate the subscriber in a given subscriber session. The use of this trust model enables services and other access rights to be provided to a subscribed which match the level of authentication which has been applied to the subscriber during any particular session.

Abstract: A communication system and method is disclosed. The communication system comprises: a mobile communication device configurable to communicate using one of a plurality of communication protocols; and a configuration server.

Abstract: Subscribers to a communications infrastructure, such as a GPRS network, can pre-pay for use of metered resources of the infrastructure. When a pre-payment subscriber joins the network, the current credit amount for the subscriber is distributed as credit values between user-specific virtual purses each associated with a respective metered resource. Upon use of a metered resource by the subscriber, the credit value held in the associated purse is correspondingly reduced, with use of the resource being dependent on the purse being in credit. The virtual purses are preferably electronically distributed to be close by the metered resources to which they relate whereby to reduce network billing traffic. When the subscriber leaves the network, the remaining credit values are consolidated from the purses.

Abstract: A user is pre-qualified for a service provided at a particular location. Location data indicative of where the service is to be triggered and a service element are stored. The service instance element is a full customised instance of the service delivery code or other item that provides an association between the user and an instance of the service for which the user is qualified. The user location, as indicated by a mobile entity associated with the user, is periodically checked against the location data. When a location match occurs, the service instance for which the user has been qualified is executed to deliver the required service to the user. An example is an airline traveler buying, from a travel agent, an air ticket having an associated service wherein, the traveler, upon arriving at the relevant airport, is contacted via its mobile device and guided through check-in and boarding.

Abstract: A system for providing services to subscribers of a network supports the provision of a plurality of different services to multiple subscribers. A first processing unit comprises a web container and provides a first execution environment for a first set of software applications. A second processing unit provides a second execution environment for a second set of software applications. One of the processing units comprises a state identification unit for identifying dynamic session-based state information, and the delivery of services by the first and second processing units takes into account the dynamic state information. This can facilitate the delivery of services in a manner which is tailored more closely to subscriber requirements, which vary in a dynamic manner.
