Embodiment Construction

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] figure 1 is a schematic block diagram depicting a system 100 for accelerating the acquisition of operating channels in a wireless communication telephony device according to the present invention. The system 100 is applicable to a wireless communication telephony device 102 . As mentioned in the background section above, when a wireless device is powered on for the first time, the wireless device must obtain initialization information from the number assignment module (NAM) appropriate to the wireless device's current location, and obtain listed channels. System 100 enables wireless device 102 to determine and retrieve the NAM, and expedites the acquisition of channels listed in the NAM. System 100 includes positioning subsystem 104 and NAM subsystem 106 . Positioning subsystem 104 determines the current geographic location of wireless device 102 and provides that location in a location signal via an output o...

Abstract

A system and method are presented for expediting acquisition of an operating channel in a wireless communications telephone device. The method activates a wireless communications telephone device and identifies the wireless device geographical location. The method correlates a Number Assignment Module (NAM) with geographical location information and selects the NAM. The method also correlates a predetermined group of channels in a Priority Roaming List (PRL) in the selected NAM with geographical location information and selects the channel group. The method scans channels in the PRL beginning with channels in the selected channel group.

Description

technical field [0001] FIELD OF THE INVENTION The present invention relates generally to radiotelephone devices and, more particularly, to a system and method for acquiring a channel when a radiotelephone device is activated. Background technique [0002] When a wireless communication telephone device is started for the first time, the wireless device must obtain initialization information and a list of channels to which the wireless device can connect. The initialization information allows the wireless device to find a suitable carrier channel and obtain carrier system information. This initialization information is typically contained in a Number Assignment Module (NAM) preloaded in the wireless device memory. The wireless device user can also utilize the wireless device user interface to load the appropriate NAM into the wireless device. If multiple NAMs are preloaded in the wireless device memory, the wireless device user is required to manually select the NAM appropri...
