Abstract: A method for managing radio resources allocated by a radio network controller of a UTRAN radio access network, where the resources support a plurality of service requests identified by a radio access bearer service request sent by the core network and describing the required QoS as a set of RAB parameters defined by mapping with corresponding QoS parameters of the core network, the controller is provided to distribute the resources amongst the bearer services and to modulate the allocation of the resources according to the priority level associated with each of the bearer services, and the priority level is defined by the “priority level” sub-parameter of the “Allocation Retention Priority” RAB parameter, with a value determined by taking into account the value of the “Allocation Retention Priority” QOS parameter of the core network and the value of at least one QoS parameter associated with the type of service.

Abstract: A method, a server and a system for managing a session in walkie-talkie (“push-to-talk”) mode between terminals each of which has respective capacities for encoding and decoding voice and/or image signals. The terminals are logged onto the session via a server and a first wireless telecommunications network to which the terminals are connected and a second network to which the server is connected. The server comprises a data encoder/decoder. When a session is established at the request of a terminal, a sender terminal sends data encoded according to an initial type of coding to one or more receiver terminals that are connected via the server.

Abstract: The invention relates to management of radio resources allocated to communication channels each associated with requested QoS parameters in a mobile communication network, consisting of the following if there is a lack of resources when accepting a new channel request: a—identify (30, 35) channels that might be preempted and among them, select (40) the lowest priority channel using an associated priority level; b—evaluate (50, 55) the gain in resources obtained by at least partially reconfiguring it, said channel and said gain being memorized; c—check (70) if the gain achieved by memorized channels is sufficient to support said new request, d—repeat steps a to c: until the gain obtained is sufficient, in which case memorized channels are reconfigured and the new request is accepted (80), or until all channels that could be preempted have been evaluated without obtaining sufficient gain, in which case the new request is refused (90).

Abstract: A method for processing quality of service of a signaling data transport channel in a packet transmission network comprising at least one management node (4), wherein, for a data transport channel, the management node (4) receives a quality of service profile associated with said channel, containing a parameter (SI) indicating signaling, detects (E2) whether, in the quality of service profile, the signaling indicating parameter is activated so as to determine whether it is a signaling data transport channel, and in that case, processes the signaling data transport channel as a priority over any other media data transport channel during execution of at least one quality of service processing mechanism applied to the signaling data transport channel.

Abstract: A unit is provided for defining a rule to be applied to a multimedia session in a network. The unit takes into account, to define the rule, information data about the media, a policy predefined by the carrier and an access type received from a session monitoring unit and used by a terminal participating in the session to access the network.

Abstract: The invention relates to a method for managing radio resources allocated by a radio network controller of a UTRAN radio access network, said resources supporting a plurality of service requests each identified by a radio access bearer service request sent by the core network and describing the QoS required in the form of a set of RAB parameters defined by mapping with corresponding QoS parameters of the core network, said controller being provided to distribute the resources amongst the various bearer services and to modulate the allocation of said resources according to the priority level associated with each of said bearer services, said priority level being defined by the “priority level” sub-parameter of the “Allocation Retention Priority” RAB parameter, whose value is determined by taking into account, on the one hand, the value of said “Allocation Retention Priority” QOS parameter of the core network and, on the other hand, the value of at least one QoS parameter associated with the type of service.

Abstract: When two terminals (T1, T2) communicate with each other via a first service via a network, switching from the first telephone service to a second telephone service enables the two terminals (T1, T2) to continue to communicate with each other via the second telephone service. In order to carry out said switching, a telephone service transformer (6) interrupts the communication between the two terminals (T1, T2) using the first telephone service; calls the two terminals (T1, T2) in parallel via the second telephone service; and then interconnects the two terminals (T1, T2) by joining the respective communications established between the transformer (6) and the two terminals (T1, T2) in order to establish a communication between the two terminals (T1, T2) via the second telephone service.

Abstract: The invention relates to a method for managing the quality of service that applies to a packet mode mobile communications network, in particular, characterised in that it includes, in the case of a network overload when accessing the resources of the network in order to execute a service for a network subscriber, a stage that consists in the following, at the level of each of the network nodes: determining an overall priority level for said access to resources, defined by a combination of at least one quality of service parameter related to the type of service and at least one quality of service parameter corresponding to the subscriber priority level, and applying at least one predefined quality of service process to the data stream that corresponds to said service, according to said determined overall priority level.
