Abstract: The invention introduces a method to inform/configure a peer-to-peer application environment such that an application can find good alternatives for peer selection and data exchange taking the network configuration conditions including caching strategies and deployment into account. In use, a mobile operator stores a tracker file that is used to provide information of likely locations of a data file sought by an end user. The mobile operator provides instructions to a mobile communication device of the end user regarding the location of a tracker file that is available for use by said mobile communication device. In this way, the mobile operator controls the peer-to-peer environment available to the end user.

Abstract: A system is provided for establishing a communication session with a terminal (i.e., terminating SIP client). The system includes a network node (e.g., SIP proxy) located in a network across which an originating client is capable of communicating. The network node is capable of sending a trigger to the terminal independent of the network. The network node is also capable of receiving a registration message, in response to the trigger, from the terminal across the network. In this regard, the network node is capable of receiving the registration message to thereby identify the terminal across the network such that a communication session is capable of being established with the terminal based upon the identity of the terminal across the network.

Abstract: A system by which paging can be performed to support global reachability in a heterogeneous multi-access environment independently on a particular radio access network architecture. Various embodiments of the present invention provide methods for performing generic paging in heterogeneous multi-access networks based on incoming traffic and its characteristics, producing a topology-based coverage map of dynamic access networks. The framework of the various embodiments of the present invention supports the use of user preferences in the selective paging process; i.e. the most optimal radio access is activated according to user preferences and the current networking environment.

Abstract: A system and method for transmitting data in a communication system. First encapsulated data is received at a first node, and second encapsulated data associated with the first encapsulated data is generated at the first node. The first encapsulated data and the second encapsulated data are transmitted independently to one or more further nodes.

Abstract: A method for caching data is disclosed, in which a network apparatus (401) partitions (600) the data into chunks to be stored in at least one priority cache and in at least one secondary cache. In response to receiving (602), in the network apparatus (401) a content request message (601) related to a user terminal (403), the apparatus checks (602) whether prioritized chunks of the requested content are available in a priority cache, the apparatus transmits (603) the prioritized chunks of the content from the priority cache to the user terminal (403). The apparatus (401) also retrieves non-prioritized chunks of the content to the priority cache from a secondary cache, wherein the retrieved non-prioritized chunks are transmitted (605) to the user terminal (403).

Abstract: A method for automated selection of an access interface and a source address for communication between a communication device and a network node in a communication system, comprising: executing a first selection routine for considering at least one first policy on access interface allocation; and executing a second selection routine for considering at least one second policy on source address allocation; wherein at least one first output of the first selection routine is inputted into the second selection routine or at least one second output of the second selection routine is inputted into the first selection routine.

Abstract: A system and method for dynamically instantiating a communication interface between a requesting entity and a client entity. A requesting entity transmits a trigger signal to a control point, where the trigger signal includes a preferred communication configuration. The control point inspects the preferred communication configuration and, if possible, instantiates a communication link that complies with the requested configuration. The communication link is deactivated either in response to a timing function, upon determining that the requesting and client entities have completed their data exchanges, or determining that an amount of time provided for the communication has expired.

Abstract: The present invention concerns a method and a system for minimizing message processing latency in a communication network. A message from a first node is received at a second node which message requires an acknowledgement message, preferably of Boolean type. Functionalities required for processing the message are partitioned into at least a first part and a second part. The first part comprises a minimum set of functionalities required to generate the acknowledgement message. The functionalities of the first part are executed. The acknowledgement message is generated and transmitted to the first node after to finishing the functionalities of the first part. The present invention makes it possible to effectively minimize the perceived message processing latency. It is also possible to dynamically optimize the latency according to available resources.
