Abstract: A traffic accident prevention service provides a method for improving traffic safety by using beacons. Each vehicle participating in the traffic accident prevention service includes a system for determining the speed of the vehicle, and a terminal connected to the system that has access to a wireless access network. Positioning beacons are located at different points of the road network and communicate via radio with the vehicles circulating close to them. The network warns the terminal of the safety parameters by knowing the position of the vehicle when it passes close to a beacon so that the driver can take appropriate actions.

Abstract: The invention relates to a system enabling IP (internet protocol) services for user terminals based on SIP (session initiation protocol) signaling applicable in fixed and mobile terminals (1) of user (2) provided with means of access to an IP network (5) connected to an IMS network (6) communicating with other terminals (1) of user (2) or other services (3). It comprises a communications interface (15) connecting an application processor (7) with at least one access module (26-34) connected to an SIP signaling module (10) for the interaction of the application processor (7) by means of events with other terminals (1) of user (2) and with services (3). It comprises an event dispatcher module (19) receiving the produced events and in which the processor (7) loads filtration criteria of the events required by each application, to send each received event to the applications (8) requiring it.

Abstract: A method for preventing overload in telecommunications networks with IMS by always-on for a call received by a user. The user sends a request message in order to activate a new PDP Context to his SGSN, which sends it to a GGSN. The GGSN sends an Accounting Request message to an AAA server. If the GGSN is going to deactivate the user PDP Context for having been inactive, the association is not eliminated from an AAA server in which this association has been saved and, when an incoming call is received: the status of the user PDP Context is verified by an indicator, and if it is not active, the PDP Context is reactivated, and if the IP address has not been assigned to another user, an attempt is made to reactivate the PDP Context; and if said IP address has already been assigned, a restart is carried out after the failure of the call.

Abstract: A method for preventing overload in telecommunications networks with IMS by always-on for a call generated by a user, in which process the user makes a PDP Context request and a GGSN of said network provides a free IP address to him or her and the PDP Context becomes active. An S-CSCF of the network creates a record in which an association between the IP address and a characteristic identity of the IMS network is included. When the GGSN is going to deactivate the PDP Context for having been inactive for a preestablished time, an indication of such deactivation is sent to the IMS client which maintains the characteristic IMS identity-IP address association and marks it as fictitious. When the user generates a new call, the IMS client informs the UMTS terminal about the characteristic IMS identity-IP address association marked as fictitious, and the UMTS terminal sends a PDP Context request message, in which message the IP address of the IMS association is included.

Abstract: Method for SIM card replacement, aimed to obtain the functionality of a first SIM card storing a real IMSI number associated to a real MSISDN (MSISDNrA,MSISDNrB), the method comprising: providing a user with a replacement SIM card storing a fake IMSI number (IMSIfA,IMSIfB); associating the fake IMSI number (IMSIfA,IMSIfB) with a fake MSISDN (MSISDNfA,MSISDNfB); setting unconditional call forwarding of all incoming calls aimed to the real MSISDN (MSISDNrB) to the fake MSISDN (MSISDNfB); for each call originated from a calling mobile station (1af) using a replacement SIM card, replacing the calling party number (MSISDNfA) with the real MSISDN (MSISDNrA).

Abstract: The invention relates to a method for preventing overload in telecommunications networks with IMS by always-on for a call received by a user; if the GGSN is going to deactivate said user PDP Context for having been inactive, the association [user IP, GGSN IP, SGSN IP] is not eliminated from an AAA server in which this association has been previously saved, and furthermore the P-CSCF in which said user is located adds an indicator that said user is registered in IMS but without an active PDP Context; and, when an incoming call is received: the P-CSCF verifies the status of the user PDP Context by means of said indicator, and if it is not active, said PDP Context is reactivated for which the P-CSCF informs the GGSN about the IP address which must be assigned to said user, and if said IP address has not been assigned to another user, an attempt is made to reactivate the PDP Context using the address given by the P-CSCF for which the GGSN uses the Network-Requested PDP context activation procedure, a consul

Abstract: The invention relates to a method for improving traffic safety by means of using beacons, using for each vehicle (3) participating in the accident prevention TAP service means (1) of determining the speed of the vehicle and a terminal TE (2) connected to said means (1) and with access to a wireless access network (4). It further uses positioning beacons (6) located at different points of the road network (8), communicating through radio with the vehicles circulating close to them. By knowing the position of the vehicle (3) when it passes close to a beacon (6), the network (4) warns the terminal TE (2) of the safety parameters (maximum speed allowed, safety distance with the vehicle in front of it) at the point of the road network (8) in which the vehicle (3) circulates. The terminal (2) warns driver of said safety parameters so that he or she can take the appropriate actions.
