A system, device, and method provide for the selection of a device to perform a service using context information for the device. The context information may be included in a request from a control point device to the device or may be included in a response from the device to the control point device. The context information provides additional information relative to the services provided by the device or relative to the device itself. For example, if the device is a camera, the camera may include for each photograph taken by the camera a date the photograph is taken, a time the photograph is taken, a location at which the photograph is taken, a subject matter of the photograph, a temperature at the photograph location, a photographer, etc in the context information. Additionally, the camera may include the current geographic location of the camera in the context information.

Application layer signaling is provided from users registering at a presence server for a presence service wherein upon reception the signaling is checked for spatial location information and stored for future use in providing the presence service in association with other user information, such as user identity. The application layer signaling may be in accordance with the session initiation protocol (SIP) and the spatial location information provided as a spatial location payload (SLoP). The presence service may provide access to the spatial location information to one or more location based services either openly or confidentially by hiding the user's identity and other information. The spatial location information may also be used in conjunction with a messaging service for providing messages to the users with enhanced functionality.

The invention relates to a method for handling a request by a first communication deviceconnected to a network of a communication system to establish a packet switched session with a second, wireless communication device, which session requires the second communication deviceto be connected to a network which enables the establishment of the session. In order to enable an enhanced handling of such a request, it is proposed that it is first determined whether the second communication deviceis currently connected to such a network. In case it is determined that the second deviceis not connected to such a network, a corresponding indication is transmitted to the first device. The user of the first deviceis then informed via the first devicethat the requested session cannot be established. The invention relates equally to a communication system enabling such a method and to corresponding elementsof such a system.

Handling a request to establish a packet switched session

Mapping functionality is added in between a Wireless Village (WV) server and a Presence, Messaging and Group (PMG) server of a 3GPP IP (Internet Protocol) Multimedia Subsystem (IMS) to permit interoperability between WV and IMS clients for instant messaging and presence services for operators who have deployed both IMS and WV. Due to the possibility that an operator may have deployed WV but not IMS and due to the use of a Client-to-Server Protocol (CSP) between WV clients and WV servers and the use of a Server-to-Server Protocol (SSP) between WV servers, the mapping functionality is structured to permit an IMS device to register into WV system via an IMS/WV Relay that performs an SIP/CSP conversion to emulate a WV device login but to then use the SSP to maintain a session or to deliver a message or presence information. Likewise, a WV device can register directly into IMS for operators not deploying WV using the mapping functionality of the present invention, e.g., in an IMS/WV Relay.

The invention relates to a method for communicating codec related information between a first mobile communication device (UE) and a second mobile communication device (UE) via a network. The codec related information relates to operational modes of an adaptive multi-rate (AMR) codec. The information is transmitted by the first mobile communication device (UE) to the second mobile communication device (UE) in a form of a binary mask in an SDP (Session Description Protocol) body () of a SIP (Session Initiation Protocol) INVITE message (), a value of 1 indicating the operational modes which are supported by the first mobile communication device (UE). In the event that the network does not support at least one of the operational modes that the codec related information indicates as being supported the network modifies the codec related information accordingly.

Communication of codec information

Application-layer signaling of a packet data network, such as the Session Initiation Protocol (SIP), is used to communicate with an interworking interface between the packet data network and a circuit-switched network, particularly a public land mobile network (PLMN), wherein the interface converts the application-layer signaling of the packet data network to a control protocol utilized in the PLMN, wherein a private user identification is carried, for example, by means of a Session Description Protocol (SDP) within the application-layer signaling between the packet data network terminal and the interface, and wherein standardization of lower layers of the packet data network protocol stack is not required beyond that which is already defined. The interface between the packet data network and the circuit-switched network provides the private user identification to the circuit-switched network in the manner in which the circuit-switched network is accustomed.
