A method for initiating an MCData communication within a regroup of communication groups, the method being implemented by a network according to the 3GPP MCS standard, wherein an MCData communication may include short data messages or file distribution. In addition, some information is added in the different transmissions to allow additional verifications by the different entities.

A method for distributing a file in a network according to the 3GPP standard includes transmitting, by the first client entity, a file distribution request including the first address, modifying, by the gateway, in the file distribution request, the first address to a second address, transmitting the file distribution request including the second address to the second content server, modifying, by the second content server, the second address in the request to a third address, transmitting the request including the third address to the second client entity, transmitting, by the second client entity, a request to download the file comprising the third address to the content server, receiving, by the second client entity, the file, and storing, by some entities, correspondences between the addresses.

Method for the file distribution between interconnected 3GPP MCData systems

A method for monitoring the connection between a first node and a second node of a communication network, includes selecting a session established between the first node and the second node, the selected session becoming a monitoring session, monitoring the connection between the first node and the second node via the monitoring session.

Method for supervising the connection between two nodes of a communication network

A communication network enabling a plurality of user devices to access communication services, the communication being a private communication or a communication within a multimedia group to which at least one user device of the plurality of user devices is affiliated, the communication network including at least one dedicated signalling group making it possible to announce to at least one user device of the plurality of user devices affiliated to the dedicated signalling group the availability of at least one service for the dedicated signalling group.

Interoperability device for interconnecting several communication networks, associated system and method

A method for configuring access by a user to fallback communication services, includes sending by an application client an authentication request to an identity management server; and in the event of rejection: the identity management server allocates a fallback identifier and sends the fallback identifier to the application client; the application client sends a request for fallback user profile to a configuration management server; the application client sends a request for fallback multimedia group profiles to a multimedia group management server; the application client sends a request for fallback multimedia group encryption keys and private communications encryption keys to an encryption keys management server; once the application client has received the fallback user profile, the fallback multimedia group profile(s), the fallback multimedia group encryption key(s) and the private communications encryption key(s), the user can access the fallback communication services.

Method for configuring access to fallback communication services and associated system

A method of communication between a first communicating entity and an application server, includes establishing a first sequence of exchanges of candidates; generating a first transmission channel establishing a first application session; detecting by a first communicating entity a new access network including a second gateway, resulting in the establishment of a second sequence of exchanges of new candidates; automatic configuring the configurable gateway so as to modify the correspondence between the source address of the second NAT gateway with the peer reflexive address of the NAT gateway which is configurable from the history of the candidates sent by the communicating entity; generating a second transmission channel maintaining the first application session.
