Abstract
Abstract A method and system used in a wireless network that provides communication service on both analog control channels (ACCs) and digital control channels (DCCHs) controls access to wireless services by a mobile station. The method comprises the steps of acquiring wireless services on a select ACC; periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC; initially attempting to acquire wireless service on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not, then indicating the preferred DCCH as rejected; storing information on the rejected DCCH; and subsequently attempting to acquire wireless service on the rejected DCCH only if the DCCH was rejected due to received signal strength not being acceptable.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
131 words
A method for use in a wireless network that provides communication services on both analog control channels (ACCs) and digital control channels (DCCHs), to control access to wireless services by a mobile station, the method comprising the steps of: acquiring wireless services on a select ACC; periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC; initially attempting to acquire wireless services on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not then indicating the preferred DCCH as rejected; storing information on the rejected DCCH; and subsequently attempting to acquire wireless service on the rejected DCCH if the DCCH was rejected due to receive signal strength not being acceptable.
Claim 2
Independent Claim
131 words
A method for use in a wireless network that provides communication services on both analog control channels (ACCs) and digital control channels (DCCHs), to control access to wireless services by a mobile station, the method comprising the steps of: acquiring wireless services on a select ACC; periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC; initially attempting to acquire wireless services on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not then indicating the preferred DCCH as rejected; storing information on the rejected DCCH; and subsequently attempting to acquire wireless service on the rejected DCCH if the DCCH was rejected due to receive signal strength not being acceptable.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein the storing step includes storing channel number, hyberband and digital verification color code associated with the rejected DCCH.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein the storing step includes storing an indicator of the reason that the DCCH acquisition was rejected.
Claim 5
Dependent Claim
28 words
The method of claim 3 wherein the storing step includes storing the reasons that the DCCH was rejected as due to signal strength, due to service or unknown.
Claim 6
Dependent Claim
22 words
The method of claim 1 wherein the storing step includes storing a minimum signal strength necessary to camp on the rejected DCCH.
Claim 7
Dependent Claim
25 words
The method of claim 1 wherein in subsequently attempting to acquire wireless service on the rejected DCCH the mobile station obtains a signal strength measurement.
Claim 8
Dependent Claim
14 words
The method of claim 6 further comprising the step of averaging signal strength measurements.
Claim 9
Dependent Claim
24 words
The method of claim 6 wherein further comprising the step of resetting the DCCH to preferred if the subsequent received signal strength is acceptable.
Claim 10
Dependent Claim
26 words
The method of claim 1 wherein the storing step includes storing information indicating if a wireless service provider for the acquired ACC is acceptable or unacceptable.
Claim 11
Dependent Claim
41 words
The method of claim 9 further comprising the step of starting a triggered scan timer if on an unacceptable service provider or if on an acceptable service provider and the rejected DCCH was rejected because received signal strength was not acceptable.
Claim 12
Dependent Claim
21 words
The method of claim 10 further comprising the step of resetting the DCCH to preferred after the triggered scan timer expires.
Claim 13
Dependent Claim
163 words
A mobile station for use in a wireless network that provides communication services on both analog control channels (ACCs) and digital control channels (DCCHs), the mobile station comprising: a receiver and transmitter for communicating with the wireless network via ACCs and DCCHs; and a programmed controller operable to control the receiver and transmitter and operating in accordance with a program stored in a memory to acquire service including acquiring wireless services on a select ACC, periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC, initially attempting to acquire wireless services on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not then indicating the preferred DCCH as rejected, storing in the memory information on the rejected DCCH, and subsequently attempting to acquire wireless service on the rejected DCCH if the DCCH was rejected due to receive signal strength not being acceptable.
Claim 14
Dependent Claim
163 words
A mobile station for use in a wireless network that provides communication services on both analog control channels (ACCs) and digital control channels (DCCHs), the mobile station comprising: a receiver and transmitter for communicating with the wireless network via ACCs and DCCHs; and a programmed controller operable to control the receiver and transmitter and operating in accordance with a program stored in a memory to acquire service including acquiring wireless services on a select ACC, periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC, initially attempting to acquire wireless services on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not then indicating the preferred DCCH as rejected, storing in the memory information on the rejected DCCH, and subsequently attempting to acquire wireless service on the rejected DCCH if the DCCH was rejected due to receive signal strength not being acceptable.
