The underlying invention generally relates to the field of mobile computing in a wireless mobile networking environment with distributed multimedia applications (130). More specifically, it is directed to the field of Quality-of-Service (QOS) management for adaptive real-time services running on mobile devices and an End-to-End Negotiation Protocol (E2ENP) based on a novel usage of a session-layer protocol (SIP) in conjunction with extensions of a session description protocol implementation (SDP, SDPng) and the Extensible Markup Language (XML) for defining user profile and terminal capability information which allow to enforce and use hierarchical QOS Contract specifications. Thereby, said End-to-End Negotiation Protocol (E2ENP) is applied to derive negotiable information, which enables a prenegotiation, fast negotiation and a fast, dynamic re-negotiation of the end-to-end quality and capabilities for a telecommunication session, for multiple configurations of two or a multiplicity of end peers and / or middleware in a consistent, reliable, and incremental way by enabling the mobile applications to efficiently and timely react to QoS violations. Furthermore, the invention pertains to the concept and realization of a novel E2ENP User Agent (128) which encapsulates the signaling part of E2ENP and expresses the information to be negotiated in an interchangeable format in such a way that heterogeneous applications (130) can easily agree on a reference model applied to orchestrate local, peer, and network resources according to the preferences and profiles of the respective user in a coordinated manner. According to one embodiment of the invention, the employed E2ENP sessionlayer protocol Application Programming Interfaces (101a-e) are independent of the actually used session-layer protocol and session description protocol implementations.

A method for determining a transmission time of collected context information at a sensor node in a communication system that includes a client, at least one sensor node collecting context information, and an access point (AP) forwarding the context information received from the sensor node to the client. The communication system operates in a session layer of protocol layers of open systems interconnection (OSI). The sensor node calculates a transmission period in which the collected context information is transmitted, and randomly determines a transmission time at which the context information is transmitted within the calculated transmission period. Since the collected context information is transmitted at the transmission time randomly determined by the sensor node, the load on the AP can be balanced.

The invention discloses a session social recommendation method based on context neighborhood modeling. According to the method, based on historical interaction data and social network information of agiven target user, the next item most likely to be interacted by the target user is found out. According to the method, firstly, user interests are modeled, and then the representation of each friendin a social network corresponding to a target user is obtained by adopting a session-level attention mechanism. And the social influence of friends on the user is learned by using a social network. And finally, article recommendation is performed in combination with the social influence of friends on the target user and the interest of the target user. The method overcomes the defects in the existing method that the interests between the target user and friends are ignored and only partially coincide. Therefore, compared with an existing method, the recommendation effect implemented by the method is remarkably improved.
