Abstract: In one aspect, there is provided is a method for preventing congestion at radio access in a mobile or wireless communication system, said method comprising, in an embodiment, a step of: barring a Mobile Terminal from radio access, except if said Mobile Terminal belongs to a given one of different ranges into which Mobile Terminals are split, said given range being referred to as allowed range, said allowed range changing upon time.

Abstract: In an embodiment, there is provided a method for handling Machine to Machine M2M services in a communication system, said method comprising a step of, for charging for IP Connectivity Access Network IP-CAN bearer services in said communication system: providing global charging information for a plurality of terminals using a same M2M service.

Abstract: In order to manage at least one communications device (DC) implementing an application that uses a service offered by an application server (SA) over a telecommunications network (RT), the device (DC) comprising application data (DonA) specific to the application and communication data (DonC) related to communication parameters for the operation of the service over the telecommunications network, the communication data (DonC) being managed by a management server (SG), the application server (SA) and the device (DC) negotiate and save an encryption key (Kc), and exchange messages by means of the management server (SG), at least one of the messages comprising application data (DonA) which is encrypted with the key by at least one of either the device (DC) or the server (SA).

Abstract: In order to accept a new call for setting up in a UMTS network node, the method consists in particular in: calculating for the new call an equivalent passband as a function of: the quality of service requested for the new call; and the quality of service attributes of the UMTS medium corresponding to the call; then comparing the sum of the equivalent passband for the new call plus the equivalent passbands of all of the calls already set up in the UMTS network node with a predetermined maximum value; and accepting the new call with guaranteed requested quality of service only if the sum is less than or equal to said predetermined maximum value.
