Abstract
Methods and systems for IMEI registration are provided. In accordance with exemplary embodiments of the present invention, when an IMEI registration fails due to a network failure, the mobile station implements a back-off algorithm for future IMEI registration attempts. Specifically, the present invention provides a back-off algorithm which determines a different amount of time for the time period between each unsuccessful IMEI registration.
Claims39
A method of registering a subscriber unit with a network, the method comprising the acts of:
- transmitting an equipment identifier over the network;
- determining if a subscriber identifier has been received in response to said transmitting act, and, if not;
- determining a wait period based on a number of previous attempts to register said subscriber unit with the network;
- and
- re-transmitting said equipment identifier over the network after said wait period has elapsed.
A communication network, comprising:
- a base station;
- a subscriber unit in wireless communication with said base station, wherein in order to register with said communication network, the subscriber unit:
- transmits an equipment identifier to the network,
- determines if a subscriber identifier has been received in response to the equipment identifier, and if not,
- determines a wait period based on a number of previous attempts to register said subscriber unit with the network, and
- re-transmits said equipment identifier over the network after said wait period has elapsed.
A method of registering a subscriber unit with a network, the method comprising the acts of:
- transmitting an equipment identifier wirelessly to the network for a plurality of registration attempts, wherein said plurality of registration attempts is equal to the lesser of a number of equipment identifier transmissions needed to register said subscriber unit, and a predetermined number of times;
- determining if a subscriber identifier has been received in response to said transmitting the equipment identifier for each of said plurality of registration attempts;
- and
- determining a wait period between each of said plurality of registration attempts.
