Abstract
An apparatus and method are provided for a communication device for locating a wireless service provider in a multi service-provider environment. The communication device has a stored search schedule associated with a plurality of frequencies. A
processor determines whether a last frequency used by the communication device has an optimal service provider. If the last frequency used does not have an optimal service provider, one of the stored frequencies is examined until a frequency is located having an acceptable service provider.
processor determines whether a last frequency used by the communication device has an optimal service provider. If the last frequency used does not have an optimal service provider, one of the stored frequencies is examined until a frequency is located having an acceptable service provider.
Claims (16)
1. A method for a communication device to locate a wireless service provider in a multi service-provider environment, the communication device having a stored search schedule associated with a plurality of frequencies, the method comprising:
determining whether a last frequency used by the communication device has an optimal service provider; and if the last frequency used does not have an optimal service provider, examining one of the stored frequencies until a frequency is located having an acceptable service provider.
determining whether a last frequency used by the communication device has an optimal service provider; and if the last frequency used does not have an optimal service provider, examining one of the stored frequencies until a frequency is located having an acceptable service provider.
2. The method of claim 1, further comprising examining the at least one of the stored frequencies in an order optimized to reduce a time necessary to locate an acceptable service provider.
3. The method of claim 1, wherein the search schedule includes a prioritized list of frequencies.
4. The method of claim 3, wherein a first one of the frequencies is a home frequency of the communication device.
5. The method of claim 1, further comprising, after determining that the last frequency does not have an optimal service provider and before examining other ones of the stored frequencies, determining whether a home frequency of the communication device has an acceptable service provider.
6. The method of claim 1, further comprising registering with an acceptable service provider.
7. The method of claim 1, wherein examining one of the stored frequencies further comprises examining frequencies in the search schedule until a first frequency having a highest priority with an acceptable service provider is determined.
8. The method of claim 1, wherein examining one of the stored frequencies further comprises skipping the last frequency used if the last frequency used is in the search schedule.
9. A wireless communication device that locates a wireless service provider in a multi service-provider environment, comprising:
a memory that stores frequencies; and a processor that determines whether a last frequency used by the communication device has an optimal service provider, and if the last frequency used does not have an optimal service provider, examines one of the stored frequencies until a frequency is located having an acceptable service provider.
a memory that stores frequencies; and a processor that determines whether a last frequency used by the communication device has an optimal service provider, and if the last frequency used does not have an optimal service provider, examines one of the stored frequencies until a frequency is located having an acceptable service provider.
10. The wireless communication device of claim 9, wherein:
the memory stores a last frequency used by the communication device and a home frequency of the communication device; and the processor determines whether the last frequency used by the communication device has an optimal service provider and if the last frequency does not have an optimal service provider, the processor determines whether the home frequency of the communication device has an acceptable service provider.
the memory stores a last frequency used by the communication device and a home frequency of the communication device; and the processor determines whether the last frequency used by the communication device has an optimal service provider and if the last frequency does not have an optimal service provider, the processor determines whether the home frequency of the communication device has an acceptable service provider.
11. The wireless communication device of claim 10, further comprising a memory that stores a frequency search schedule having a prioritized list of frequencies, the home frequency used by the communication device being stored in the memory as a highest priority frequency.
12. The wireless communication device of claim 11, wherein the processor examines the last frequency used and then examines the frequencies in the frequency search schedule in a prioritized order until an acceptable service provider is located.
13. The wireless communication device of claim 9, wherein the processor causes the wireless communication device to register with the acceptable service provider.
14. The wireless communication device of claim 9, wherein:
the memory stores a frequency search schedule having a prioritized list of frequencies; and the processor determines whether a last frequency used by the communication device has an optimal service provider, and if the processor determines that the last frequency does not have an optimal service provider, the processor examines the frequencies in the frequency search schedule in a prioritized order until an acceptable service provider is located.
the memory stores a frequency search schedule having a prioritized list of frequencies; and the processor determines whether a last frequency used by the communication device has an optimal service provider, and if the processor determines that the last frequency does not have an optimal service provider, the processor examines the frequencies in the frequency search schedule in a prioritized order until an acceptable service provider is located.
15. The wireless communication device of claim 9, wherein the memory stores frequency bands, and the processor determines whether a last frequency band used by the communication device has an optimal service provider, and if the last frequency band used does not have an optimal service provider, examines one of the stored frequency bands until a frequency band is located having an acceptable service provider.
16. The method of claim 1, wherein the stored search schedule has a plurality of frequency bands, and the method determines whether a last frequency band used by the communication device has an optimal service provider; and if the last frequency bands used does not have an optimal service provider, examining one of the stored frequency bands until a frequency band is located having an acceptable service provider.
