Abstract: A cellular telecommunications system comprises a radio access portion enabling user equipment to access services of the cellular telecommunications system; and a core network portion comprising a quality of service policy control equipment connected to a gateway via which radio bearers are set up in order to access said services. An orchestrator equipment: receives regular reports from said gateway relating to the radio bearers that are set up; detects the occurrence of a crisis situation; identifies cells affected by the crisis situation; applies, during the crisis situation, crisis situation management rules, by declining to authenticate user equipment for which the crisis situation management rules indicate that access to said services is barred during the crisis situation; and by asking the gateway to close any session set up for user equipment for which the crisis situation management rules indicate that access to said services is barred during the crisis situation.

Abstract: In order to offer domain name resolution services vis-a-vis resources of various security domains of a communication network, an item of equipment, on reception of a domain name resolution request coming from a client device, performs: authentication operations checking whether the client device that sent the request was previously registered; authorisation operations checking whether the client device actually has right of access to the resources of said domain name; and domain name resolution operations by means of a cache storing associations of IP addresses and domain names. The cache is populated by means of the results of domain name resolutions performed by external name servers to which said equipment resort to via respective secure tunnels, independently of said security domains, when the cache does not include data allowing to effect the domain name resolution required.

Abstract: A method for federating at least two communication networks for mobile terminals by establishing a dedicated link between the two networks and then configuring one of the networks to use elements of the other network, in particular the user database and the communication policy manager.
