• the TE 3 terminal subscribes to the service for the first time. For this, it sends a registration request to a wireless access network 4, in charge of managing the PATSEMB Traffic Accident Prevention Service for Emergency Services through Beacons.
• the parameters included in the request are: - the service identifier PATSEMB, ID PATSEMB ;
• the wireless access network 4 has for example a database 5 with the pairs (ID VE . IDVEp A ss) allowed for the PATSEM service; Y

• an authentication mechanism for example a credential sending mechanism.
• network 4 and user using the user's identity and password parameters as input, network 4 and user generate a response that must be the same at both ends to consider the user authenticated and facilitate access. As the calculation of that response is based on something that only network 4 and user know, if the answer is the same, it is the registered user.
• Network 4 will verify that the pair (ID V E. IDVE PASS ) is correct. If it is not correct, it will reject the request.
• step P3 If it is correct, I will confirm your subscription to the PATSEMB service and send to the TE 3 terminal a temporary ID of the IDVE TEMP - P4 emergency vehicle. If in step P1 the emergency vehicle 1 was not able to enter its position, optionally the network 4 will attempt to calculate its position and inform the other vehicles as described in step P7. Otherwise, the network will inform the rest of the vehicles as described in step P7.
• the TE 3 will be put into listening mode so that it will be dedicated to listen to the information radiated by the beacons 6. In case the beacon 6 transmits via RFID, the terminal TE 2 will listen on the frequency referred to for this service. P6 The TE 3 when listening to the message broadcast by a beacon 6 will check the identifier of the service provided by said beacon 6. If it matches that of the PATSEMB service, ID PATSEMB , the TE 3 will send to the network 4 the identifier of the beacon, ID 6 and its IDVE ID TEMP - Another possibility is that the TE 3 sends this data to the beacon 6 and it forwards it to the network 4, as shown in Figure 2 and is contemplated in claim 6.
• the network 4 stores then the values received in the database BD 5 of the service, confirms to the terminal TE 3 the reception of the data sent, and informs the rest of vehicles 7 of its presence, as described in step P7.
• P7 The rest of the vehicles 7 are informed of the presence of the emergency vehicle 1 in the vicinity of the beacon 6.
• a- The network informs the rest of the vehicles that are less than a predetermined distance of The beacon 6 of the presence of the emergency vehicle 1.
• b- The network informs the appropriate beacons to disseminate particular information, such as maximum allowed speed, particular instructions such as clearing a lane, etc.
• the information sent to these vehicles will depend on where they are:
• the network 4 will send an update of the safety parameters and may request a lane change.
