Abstract: A method for controlled delivery of a service from a server (S) to a client (C), includes the steps of sending a download descriptor, from server (S) to client (C), retrieving of the service by the client, sending of a first type confirmation message by the client, activating the service by the client (C), wherein the service is first transformed within the server (S) into a sequence of individual blocks, wherein download descriptor (descn) and first type of confirmation message (confn) are generated and transmitted per at least one block of said sequence, and wherein the first type confirmation message (confn) is sent upon receipt of said at least one block by said client (C).

Abstract: Customer triggered resource reservation requests (131) are granted or refused in an access node (104) on the basis of available resources on downlinks (102) between the access node (104) and customer premises, and eventually uplinks (105) between the access node (104) and an aggregation network (106). Network triggered resource reservation requests (121) are granted or refused in a central resource admission control device (108) on the basis of knowledge of available resources in the aggregation network (106) and the contents of an admission control report (123) received from the access node (104). The admission control report (123) is generated by the access node (104) on the basis of available resources on downlinks (102) between the access node (104) and customer premises, and eventually uplinks (105) between the access node (104) and an aggregation network (106).

Abstract: To resolve a Uniform Resource Identifier (URI) for use in routing messages in or between IP Multimedia Subsystem (IMS) networks, a query (101;201) is sent to resolve this URI from a device (120;220) to a private name server (121;221). The private name server (121;221) attempts to resolve the URI. In case of failure the method further involves the sending of a new query (104;203) for resolving the URI to a public name server (122;222). The public name server (122;222) resolves the URI in the new query (104;203).

Abstract: A telecommunication network (TN) comprises a radio access network (2) defining cells in which user equipments (7) are localized and a core network (1) linked to the radio access network and adapted to establish a multimedia broadcast multicast context for the user equipments (7) located in the cells.
