For enriching presence statuses of users in a contact list with call routing rules associated with said users, the presence statuses indicating an availability of said users, called contact users, for communication and being delivered by a presence server (PS) to an application (UCA) implemented in a communication device (CD) owned by a user, called application user, the presence server: sends a request to a call server (CS) managing call routing rules of said contact users, the request containing identifiers (IdCU) of said contact users, receives a response from the call server, the response containing routing statuses (RS) of said contact users, the call server having determined call routing rules (RR) stored respectively in correspondence with the identifiers (IdCU) and having interpreted the call routing rules (RR) to create a routing status for each contact user, and sends a message to the communication device (CD), the message containing the routing status for each contact user, in order that the application (UCA) displays the routing status of contact users.

Enriched presence status

A method and a resource broker are provided to control a conference session. The resource broker receives, from a conference controller, a message requesting to set up a conference communication for a participant. The message indicates whether a terminal of the participant supports selective forwarding. The resource broker verifies the availability of local selective forwarding and multipoint control resources. Based on the capabilities of the terminal and based on local resource availability, a reply is sent to the conference controller, indicating that the conference communication should be set up in selective forwarding or multipoint control mode, using local resources or resources of a network cloud. When a new participant is added or when a monitoring agent reports a change of availability of the local resources, the conference communication may be moved between the network cloud and the local resources, or change between selective forwarding and multipoint control modes.

Methods and nodes for controlling a conference communication

A method for allocating a video conferencing task within a computer network comprising a plurality of candidate processing devices, the method comprising: for each of the candidate processing devices: determining a topological score, the topological score being a function of at least one end-to-end delay between a pair of participating endpoints through the candidate processing device; for each candidate processing device within at least a subset of the candidate processing devices: determining an availability score, the availability score being a function of an available processing capacity of the candidate processing device; selecting a preferred processing device among the candidate processing devices as a function of the topological scores and of the availability scores, and allocating the video conferencing task to the preferred processing device.
