Abstract
Methods and devices enable communication via a wireless network with moving vehicles, depending on the likelihood or presence of an emergency situation. The communication may be enabled also when an Internet connection is present.
Claims23
A method for dynamically allocating/de-allocating a Mobile Station International Subscriber Directory Number, (MSISDN) in a wireless communication network, the method comprising:
- obtaining an international mobile subscriber identity (IMSI) related to a moving vehicle to which no MSISDN is allocated;
- predicting an accident likelihood for the moving vehicle;
- determining whether the accident likelihood for the moving vehicle exceeds a first predetermined threshold;
- and
- causing an MSISDN to be allocated to the moving vehicle as a result of determining that the accident likelihood exceeds the first predetermined threshold.
(canceled)
A network device configured to selectively enable allocating/de-allocating of a Mobile Station International Subscriber Directory Number (MSISDN) to/from a vehicle, the network device comprising:
- a communication interface;
- and
- a processing unit connected to the communication interface and configured to:
- control the communication interface to obtain an international mobile subscriber identity (IMSI) related to a moving vehicle to which no MSISDN is allocated,
- predict an accident likelihood for the moving vehicle, and
- control the communication interface to send first messages causing an MSISDN to be allocated to the moving vehicle, if the accident likelihood exceeds a first predetermined threshold.
18-25. (canceled)
A method for enabling a vehicle connected to Internet to make an eCall, the method comprising:
- receiving a request to allocate an international mobile subscriber identity (IMSI) to the vehicle, the request including a unique vehicle identifier;
- allocating a temporary IMSI to the vehicle, based on the unique identifier;
- prompting a pool of available MSISDNs to indicate an MSISDN;
- and
- storing a link between the temporary IMSI and the MSISDN in a network database.
(canceled)
A network device for enabling a vehicle to make an eCall, the device comprising:
- a communication interface configured to receive a request to allocate international mobile subscriber identity (IMSI) to the vehicle, the request including a unique vehicle identifier;
- and
- a processing unit connected to the communication interface and configured to:
- control the communication interface to send messages triggering:
- i) an allocation of a temporary IMSI to the vehicle based on the unique identifier, ii) an MSISDN pool to indicate an available MSISDN, and iii) the storage of a link between the temporary IMSI and the MSISDN in a network database.
