Abstract

A mobile communication terminal device such as a cellular telephone is provided with a preliminary identifier stored in memory. The identifier allows access to a cellular network for verification and provides essentially unique identification by the network, but is insufficient to allow further use of the network. During verification, the identifier is analyzed by a cellular network processor and a determination is made whether the cellular telephone should have restricted access to the network. Upon favorable completion of the identifier analysis, a signal may be transmitted to the cellular telephone that allows the cellular telephone to have less restricted access to the network.

Claims

1. A method of controlling access by a wireless terminal to a wireless link available from a communications service provider, said method comprising:

receiving from a wireless terminal an identifier transmitted, at least in part, on the wireless link, wherein the identifier includes first and second numbers, the first number including a serial number that is permanently associated with the wireless terminal;

analyzing the identifier to determine whether the second number transmitted by the wireless terminal is a preliminary identifier, the preliminary identifier providing the wireless terminal restricted access to the wireless link, and if the second number is a preliminary identifier, analyzing a customer data record using the first and second numbers to determine whether the wireless terminal should continue to have restricted access to the wireless link; and

transmitting, upon favorable completion of said analyzing step, a signal to the wireless terminal so that the wireless terminal transmits a replacement identifier the next time the wireless terminal transmits an identifier, the replacement identifier allowing the wireless terminal to have less restricted access to the wireless link than the preliminary identifier.

2. The method of claim 1, wherein the preliminary identifier received during said receiving step includes first and second numbers that together are essentially unique to die wireless terminal.

3. The method of claim 1, wherein the wireless terminal is a cellular terminal and one of the first aid second numbers is in mobile identification number (MIN) format.

4. The method of claim 1, wherein the analyzing step further comprises transmitting a signal representative of a query to the wireless terminal at least in part on a wireless link, the query requesting data.

5. The method of claim 4, wherein the analyzing step further comprises comparing data received from said wireless terminal after the query with data in a customer data record associated with the preliminary identifier.

6. The method of claim 1, wherein the signal transmitted during the transmitting step represents the replacement identifier.

7. The method of claim 6, wherein the signal transmitted during the transmitting step also represents an instruction to overwrite the preliminary identifier with the replacement identifier.

8. The method of claim 1, wherein the preliminary identifier is associated with a customer data record available to the wireless communication network.

9. The method of claim 8, further comprising the steps of:

transmitting a query requesting data from the wireless terminal; and

comparing data received from the wireless terminal to the customer data record.

10. The method of claim 1, wherein the step of transmitting the signal to the wireless terminal further includes the step of instructing the wireless terminal to overwrite the preliminary identifier with the replacement identifier.
