Abstract

A method is disclosed for operating a mobile station. The method has a first step of storing data into a memory within the mobile station, the stored data including at least one system operator code (SOC) having an assigned priority value. Upon the mobile station receiving a system identification (SID) associated with the stored SOC, the method stores the SID into the memory so as to have the same priority value that is assigned to the SOC. When the mobile station subsequently receives a transmission containing the SID and not the SOC, the mobile station accesses the memory to determine the priority value associated with the SID, and then controls the operation of the mobile station based on the determined priority value. The step of controlling the operation of the mobile station preferably controls at least one of a scanning behavior or a camping behavior of the mobile station.

Claims

1. A method for operating a mobile station, comprising steps of:

storing data into a memory within the mobile station, the stored data comprising first descriptor information specifying an identity of at least one wireless system, the at least one wireless system having an assigned priority value; and

upon the mobile station receiving second descriptor information from a system that has first descriptor information stored in the database, storing the received second descriptor information into the memory so as to have the same priority value that is assigned to the system identified by the first descriptor information.

2. A method as in claim 1, and further comprising steps of:

receiving a transmission containing the second descriptor information and not the first descriptor information;

accessing the memory to determine the priority value associated with the second descriptor information; and

controlling the operation of the mobile station based on the determined priority value.

3. A method as in claim 2, wherein the step of controlling the operation of the mobile station based on the determined priority value controls at least one of a scanning behavior or a camping behavior of the mobile station.

4. A method as in claim 1, wherein the first descriptor information is comprised of a system operator code (SOC), and wherein the second descriptor information is comprised of a system identification (SID).

5. A method as in claim 1, wherein there are at least two wireless systems having different air interface protocols.

6. A method as in claim 5, wherein one of the at least two wireless systems is an ANSI-136 wireless system.

7. A method for operating a mobile station, comprising steps of:

storing data into a memory within the mobile station, the stored data comprising at least one system operator code (SOC) having an assigned priority value;

upon the mobile station receiving a system identification (SID) associated with the stored SOC, storing the SID into the memory so as to have the same priority value that is assigned to the SOC;

subsequently receiving a transmission containing the SID and not the SOC;

accessing the memory to determine the priority value associated with the SID; and

controlling the operation of the mobile station based on the determined priority value.

8. A method as in claim 7, wherein the step of controlling the operation of the mobile station based on the determined priority value controls at least one of a scanning behavior or a camping behavior of the mobile station.

9. A method as in claim 7, wherein there are at least two wireless systems having different air interface protocols.

10. A method as in claim 9, wherein one of the at least two wireless systems is an ANSI-136 wireless system.

11. A mobile station, comprising:

a controller;

a wireless transceiver for conducting bidirectional communications with a wireless system; and

a memory storing data representing first descriptor information specifying an identity of at least one wireless system, the at least one wireless system having an assigned priority value stored in the memory;

wherein

said controller is responsive to said mobile station receiving second descriptor information from a system that has first descriptor information stored in the memory for storing the received second descriptor information into the memory so as to have the same priority value that is assigned to the system identified by the first descriptor information, said controller being further responsive to the mobile station receiving a transmission containing the second descriptor information and not the first descriptor information for accessing the memory to determine the priority value associated with the second descriptor information, and subsequently controlling further operation of the mobile station based on the determined priority value.

12. A mobile station as in claim 11, wherein the first descriptor information is comprised of a system operator code (SOC), and wherein the second descriptor information is comprised of a system identification (SID).

13. A mobile station as in claim 11, wherein said priority value assigns said system to be one of a Forbidden system, a Neutral system, a Favored system, a Partner system, or a Home system.
