Abstract: An arrangement for generating a telecommunications application (such as a voicemail application) is described. The arrangement provides a graphical user interface that enables a user to select telecommunications application building blocks and to position and connect those blocks on the display in order to define an algorithm. The algorithm can be implemented using pre-defined modules for said building blocks.

Abstract: A heterogeneous wireless communication network includes a home access network with a home network characteristic and a home network policy, and a visiting access network with a visiting network characteristic and a visiting network policy. A packet data node gateway is adapted to communicate with the home access network and the visiting access network over a first communication path. An out-of-band communication path substantially separate from the first communication path is adapted to carry the visiting network policy from the visiting access network to the packet data node gateway. When the terminal is handed off from the home network to the visiting network, the packet data node gateway retrieves the visiting network policy, and the terminal accesses the visiting network over the first communication path using the visiting network policy.

Abstract: An architecture by which combined scheduling and network coding can be used in mesh networks, and more particularly wireless mesh networks. In various embodiments, this architecture includes a scheduling MAC protocol for scheduling nodes in the mesh network in order to take advantage of network coding opportunities. The schedule takes advantage of these opportunities by assigning a gain to transmit packets based upon the number of packets that are transmitted concurrently and choosing a schedule which minimizes the gain over the scheduling horizon. Regarding the assigned gain, in one embodiment this value is one for basic non-encoded operations and two or more for encoded operations. A scheduling MAC protocol is also used to announce and arbitrate network coding opportunities by indicating which packets (as characterized by their transmission slot) are to be encoded with each other.

Abstract: A user equipment UE context is stored in a local memory including a session context for a breakout data session. The session context comprises a source internet protocol IP address, a destination IP address, an identifier of a former local breakout gateway LBGW and an identifier of a new LBGW. The former LBGW receives first traffic originating from the destination IP address and addressed to the source IP address, and uses the session context to forward the first traffic from the former LBGW to the new LBGW via a first tunnel. There is thus a globally routable IP address for the session context that need not change when the UE moves from one LBGW to another. Embodiments are detailed for routing through more than two LBGWs, and for when the UE initiates another breakout data session on the new LBGW ion addition to the aforesaid breakout data session.

Abstract: An application is described, which application detects that a communication device of a called party is not accepting a call from a calling party and initiates a voicemail application in response to the detecting step. The voicemail application includes a plurality of voicemail modules, each of which is a complete and functional voicemail application. The initiation of the voicemail application includes selecting one of said plurality of possible voicemail modules for use, for example on the basis of the identity (or some other characteristic) of the calling party and/or the identity (or some other characteristic) of the called party.

Abstract: An arrangement is provided for detecting that a called party is not (or is not able) to accept an incoming call, such that a voicemail application should be initiated. In response to this detection, a premium voicemail service is initiated, for example by a SIP server that does not typically form part of the mobile operator of the called party. The premium voicemail service selects one of a number of available voicemail services, typically dependent on the identity of the called party and/or the calling party and provides that voicemail service. The voicemail service(s) offered by the premium voicemail service are user-definable. For example, the user may be able to purchase a particular voicemail service, modify and existing voicemail service and/or design a voicemail service.

Abstract: A voicemail module is described, which module is intended to be incorporated into a voicemail system of one or more end users. The voicemail module includes a plurality of settings, some of which may be provided by the developer and some of which may be provided by the end user. For at least some of the settings that are provided by the developer, a flag or some other mechanism is provided for indicating whether the developer allows the end user to modify the setting. Thus, a flexible voicemail module is provided that enables the developer of the module to retain control of the aspects of the module that can be configured by the end user.

Abstract: A device comprises a first binding unit which provides for a binding to a first tunnelling server using a first protocol, a second binding unit which provides for a binding to a second tunnelling server using a second protocol different from the first protocol, and an authorizing unit which causes the first or second binding unit to provide the binding.

Abstract: A method comprising transmitting a busy signal from a first node; receiving said busy signal at a second node; and transmitting data from said second node to said first node on a channel associated with said busy signal.
