Embodiment Construction

[0023] The object of the present invention is to enable a service device installed in the Internet core network and capable of performing at least one function related to providing at least one communication service to at least one (called or calling) communication terminal to notify other service devices of itself The assigned task performs the function for the specified communication duration.

[0024] For the purposes of non-limiting examples, the following assumes that the Internet (or IP) communication core network is of the IMS or MMD type, or a type derived therefrom (such as the network defined by the TISPAN group of ETSI). However, the invention is not limited to this type of core network. In fact, it concerns all Internet core networks belonging to or coupled to IP communication networks, such as PSTN or PLMN networks.

[0025] As very schematically described in the only figure, the core network NC may comprise at least one server PSi with a "proxy" function (or "SI...

Abstract

The invention relates to a device (D) which is dedicated to controlling the implementation of functions linked with providing at least one communication service to at least one communication terminal (T1) in a service device (SA1) belonging to an Internet communication network core (CR). The inventive device (D) comprises control means (MC) which, upon receipt of a request for the provision of the service offered by the device (SA1) for a given communication, are responsible for: (i) deciding to implement at least one function selected from among the functions offered by the device (SA1); and, subsequently, (ii) inserting decision-signalling data into at least one of the signalling messages emitted by the device for the communication in question, which are intended for at least some other service devices (PS1, PS2, SA2, MR1) of the network core (CR), such that they can prohibit the implementation of the selected function for the length of the given communication.

Description

technical field [0001] The present invention relates to communication networks having a core network of IP type (IP stands for "Internet Protocol"), more specifically services accessed by communication terminals, such networks making services available to their users. Background technique [0002] Here, the "communication network with an IP type core network" refers to both an end-to-end IP network and a network with an IP type core network. In the end-to-end IP network, users have IP links, and the network with an IP type core network can Accessed via a gateway by another technology. Such networks are, for example, those relying on the technology SIP ("Session Initiation Protocol"), such as IMS networks ("IP Multimedia Subsystem" (3GPP)) or MMD ("Multimedia Domain" (3GPP2)). [0003] In addition, the term "communication terminal" here refers to any communication device using radio waves or wires, fixed or mobile (or portable), which may use a gateway or gateways, capable o...
