Abstract

A set of performance-related data that represents both normal and abnormal conditions in the network is determined and stored in a mobile station MS. The set or a sub-set of this data is transmitted to a computer for analysis upon a triggering event, and the MS user is informed of the analysis results. The triggering event is receipt by the MS of an encrypted message to transmit the set or sub-set of the data. The MS decrypts the received message using an associated public key stored in the MS and transmits the set or the sub-set of the performance-related data only in response to correctly decrypting the encrypted message. The public key is one of a set of public keys stored in the mobile station, wherein individual members of the set are associated with applications executable by the MS in cooperation with a received encrypted command or encrypted data set.

5. The method of claim 1, wherein transmitting the set or a sub-set of the performance-related data comprises:

receiving the transmitted set or subset of the performance-related data at a control center associated with a network service provider; and

analyzing the data to determine an indication of an occurrence of at least one of a fault in the mobile station, a fault in a system of the network service provider, or a no fault condition.

6. The method of claim 1, wherein transmitting the set or a sub-set of the performance-related data comprises:

receiving the transmitted set or sub-set of the performance-related data at a remote diagnostic center; and

analyzing the data to determine an indication of an occurrence of at least one of a fault in the mobile station, a fault in a system of the network service provider, or a no fault condition.

7. The method of claim 1, wherein the analysis includes determining statistical information regarding a population of mobile stations.

8. The method of claim 1, wherein the analysis includes determining whether an operational fault has occurred and, if it has, determining whether the operational fault occurred in the mobile station or in the wireless network that serves the mobile station.

9. The method of claim 1, wherein transmitting the set or a sub-set of the performance-related data comprises:

receiving the transmitted set or sub-set of the performance-related data at a local computer that is coupled to the mobile station through a data interface; and

analyzing the data to determine an indication of an occurrence of at least one of a fault in the mobile station, a fault in a system of the network service provider, or a no fault condition.

10. The method of claim 1, wherein determining and storing a set of performance-related data in the mobile station comprises continually determining the set of performance-related data in the mobile station.

11. A mobile station comprising a wireless transceiver for conducting bidirectional communications with a wireless network, said mobile station further comprising a memory and a controller coupled to said memory and to said transceiver, characterized by said controller being operable for determining, during the operation of said mobile station, a set of performance-related data and for storing said determined set of performance-related data in said memory, wherein said performance-related data comprises information that represents both normal and abnormal conditions in the network and in the mobile station, said controller being responsive to an occurrence of a triggering event for transmitting said set or a subset of said performance-related data to a computer for analysis;

wherein the triggering event is comprised of a receipt by the mobile station of an encrypted message to transmit the set or sub-set of the performance-related data, and said controller being responsive to the receipt of the message for decrypting the received message using an associated public key stored in the mobile station and for transmitting the set or the sub-set of the performance-related data only in response to correctly decrypting the encrypted message,
