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.

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.

System and method for implementing a selective paging model for use in a multi-access environment

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.

Communications in relay networks

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.

Selection of access interface

Providing access for a mobile node to a communication network comprising multiple access networks operating according to different access technologies, wherein said communication network is configured to communicate by means of different access technologies with said mobile node, comprising, upon an access request of the mobile node at a first access network, preparing the access networks, other than the first one, for providing access for the mobile node in case of a handover of the mobile node to one of these other access networks.

Pro-active access handling in a multi-access network environment

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.

System and method for dynamic interface management

Disclosed herein are apparatus, methods and computer program products for using access point availability information in a wireless communications system. In aspects of the method performed at an access point in a wireless communications system, the access point generates a message indicating the level of availability of the access point; and transmits the message. In aspects of the method performed at user equipment in a wireless communications system, the user equipment receives messages from access points in the wireless communications system, the messages containing access point availability information indicating the respective levels of availability of the access points available for selection by the user equipment; and selects an access point in dependence on the access point availability information. In variants, the user equipment may perform additional steps to determine whether a current or contemplated operating mode requires selection of an access point be made in dependence on access point availability information associated with the access point. Only if the current or contemplated operating mode provides a quality of service that is dependent on level of availability of an access point will the access point availability information be consulted when selecting an access point.

According to the present invention, traffic control in an IP based network is provided. For this purpose, traffic situation in the network is measured, and the traffic flow is controlled on the basis of the measured traffic situation. Moreover, an operator may define rules for different measured situations, and the traffic flow is controlled on the basis of these rules.

Traffic control in an IP based network

A differentiated service network having a plurality of routers. An operating condition such as stability may be determined at a first router. An indication of the operating condition may be propagated from a first router to a second router such as an edge router. Based on the indication of the operating condition, one or more parameters of a constraint may be adjusted. The indication may be a signal corresponding to a network traffic status.
