Abstract
Disclosed is an apparatus for initiating an over the air parameter administration (OTAPA) of a mobile station without the need for interacting with a mobile station user. A unique service option number included with the initial page indicates to the mobile station that an update is being requested. The mobile station performs a network validation check (SPASM) before permitting the update to take place. Flags are used in the network to alert the system that an attempted update was not completed because a mobile station was not update accessible for any of several reasons. The flags cause the system to update when the mobile station next becomes update accessible.
Claims8
A method of alerting a wireless communications network that an attempt to update operational parameters in a mobile station has failed comprising the steps of:
- setting a network based over-the-air parameter administration pending flag;
- storing a network based over-the-air functional address for reinitiating the update process;
- and
- the over-the-air parameter administration pending flag is set in conjunction with home location register data when the location of a mobile station is not available.
Apparatus for alerting a wireless communications network that an attempt to update operational parameters in a mobile station has failed comprising:
- means for setting a network based over-the-air parameter administration pending flag;
- means for storing a network based over-the-air functionality address for reinitiating the update process;
- and
- means for setting the over-the-air parameter administration pending flag in conjunction with home location register data when the location of a mobile station is not available.
A method of validating a wireless communication network communicating with a mobile station comprising the steps of:
- generating a first secret word, within a mobile station, comprising a predetermined combination of a first word stored internal to the mobile station and a second word generated internal to said mobile station;
- generating a second secret word, derived from data stored at the home location network, comprising a predetermined combination of said second word obtained from said mobile station and a copy of said first word as obtained from a home location network register;
- supplying said second secret word to said mobile station;
- and
- comparing said first and second secret words within said mobile station to validate the communicating network.

- means for generating a second secret word, at the home location network, comprising a predetermined combination of said second word received from said mobile station and a copy of said first word as obtained from a home location network register;
- means for supplying said second secret word to said mobile station;
- and
- means for comparing said first and second secret words within said mobile station to validate the communicating network.
