Abstract: A communications network system with discrete terminal mobility and remote user registration associated with said mobility, which comprises at least: a terminal controller (TC) software component for maintaining and updating data of terminal configuration, access interface references of a provider agent (PA), conditions for accepting or rejecting remote user registrations, and for terminal registration or deregistration; a terminal mobility management (TMM) software component for controlling data related to the terminal connection, creating or suppressing registered terminal agents (TA), checking discrete terminal mobility subscription, maintaining subscription agent (SubA) references of the subscribed terminals with discrete mobility, and obtaining references of terminal agents (TA) for terminals with discrete mobility in other federated retailer domains (1).

Abstract: Method for distributing radio channels in a radiocommunications system in which a fixed unit (11-j) allocates radio channels to a plurality of remote units (12-1 to 12-m), and in which the radio channels are defined by a time slot of a frame and a pseudo-random sequence. Processor means carry out an analysis of the quality requirements in relation with an incoming, or in process, or foreseen incoming call, and of a list of occupied channels prepared by the fixed unit (11-j), with the object of releasing, by means of a handover procedure, a busy channel on the list and belonging to a time slot having the quality closest to that required for the call to which it is desired to allocate a channel. The fixed unit (11-j) allocates to said call the time slot that includes the released radio channel.

Abstract: System and method for confirming calls in a telephone system. The method is based in that a user subscribed to this service has the option of selecting a call confirmation state. According to the method of the invention, a user selects an incoming call confirmation state, and in the event of a call occurring for this user, the calling party receives a confirmation request by means of a message that is sent to him from a control center (5), this latter party being that which decides to set up the call. Said control center (5) is situated either in the telephone network or in the telephone terminal itself.
