Abstract
An apparatus and method for fast signal acquisition on a preferred communication channel is disclosed. The apparatus includes a frequency and identification guidance system that can have a hardware as well software implementation. The memory of the device includes a prioritized multi-level system of channels and a prioritized multi-level system of identifiers. The frequency and identification guidance system utilizes both multi-level systems to guide the device to a channel belonging to the preferred Service Provider.
Claims1
A method of fast signal acquisition on a preferred wireless frequency channel by a wireless communication apparatus said wireless communication apparatus including a memory and a frequency and identification guidance system, said method comprising the steps of:
- (A) configuring said frequency and identification guidance system by:
- (A1) storing a multi-level system of channels in a first main list of said memory;
- and
- (A2) storing a multi-level system of identifiers in a second main list of said memory;
- and
- (B) selecting said preferred wireless frequency channel provided by at least one radio transceiver by utilizing said frequency and identification guidance system, said one radio transceiver being a part of a plurality of networks of external radio transceivers,
- (B1) selecting a highest priority level in said multi-level system of identifiers;
- (B2) checking a channel level with the 1-st highest priority including a first plurality of channels to achieve the preferred connection:
- (B3) if a preferred connection is not achieved in the step (B2), checking a channel level with the 2-nd highest priority including a second plurality of channels to achieve preferred connection:
- (B4) if a preferred connection is not achieved in the step (B3), checking consecutively each channel level with the i3-th priority including an i3-th plurality of channels to achieve preferred connection, i3 being an integer greater than two and less than or equal to N, wherein said first main list includes a plurality of N levels with different priority wherein N is an integer greater or equal to one;
- (B5) selecting the next highest priority level in said multi-level system of identifiers, if a connection is not achieved;
- and
- (B6) repeating said steps (B2-B5) until said preferred connection is achieved, wherein the step of checking the channel level with the next highest priority if a preferred connection is not achieved in the preceding step, further comprises the steps of:
- (a) arranging at said channel level with the next highest priority a plurality of channels in order of highest channel priority to lowest channel priority and marking said arrangement of channels as a prioritized channel list;
- (b) selecting a channel with the highest channel priority on said prioritized channel list;
- (c) checking whether the strength of the received signal on said selected channel is above a threshold;
- (d) checking whether communication is available on said selected channel;
- (e) confirming said selected channel if the second main list including a multi-level system of identifiers is not used;
- (f) confirming said selecting channel if the second main list including said multi-level system of identifiers is used and if said selected level of identifiers in said second main list includes the identifier provided by a network of external radio transceivers during the communication step (d);
- (g) selecting a channel with the next highest channel priority on said prioritized channel list, if said selected channel is not confirmed;
- and
- (h) repeating said steps (c-g).
