REFERENCE TO RELATED APPLICATIONS This application discloses subject matter related to the subject matter disclosed in the following commonly owned co-pending U.S. patent application(s): (i) �SYSTEM AND METHOD FOR ACCELERATING NETWORK SELECTION BY A WIRELESS USER EQUIPMENT (UE) DEVICE,� filed Jul. 1, 2005; application Ser. No. 11/173,083, in the name(s) of: Adrian Buckley, Andrew Allen and G. Scott Henderson and (ii) �SYSTEM AND METHOD FOR ACCELERATING NETWORK SELECTION BY A WIRELESS USER EQUIPMENT (UE) DEVICE USING SATELLITE-BASED POSITIONING SYSTEM,� filed Jul. 1, 2005; application Ser.

FIELD OF THE DISCLOSURE The present patent disclosure generally relates to communication networks. More particularly, and not by way of any limitation, the present patent application is directed to a system and method for facilitating accelerated network selection by a wireless user equipment (UE) device.
BACKGROUND When a wireless user equipment (UE) device is first powered up or when it tries to recover from loss of coverage, it is typically required to search for its last registered Public Land Mobile Network (RPLMN) in every supported radio access technology and frequency bands associated therewith before attempting to register on another PLMN. The issue for operators is that when a UE device powers up after a power off condition and subsequent relocation to a new location, it may have to perform a full band scan (FBS) of all supported bands before possibly selecting a National Roaming Partner (NRP). Today, such a full scan already takes a fairly long time in a dense or complex radio environment, which will be further exacerbated when additional frequency bands are introduced and more access technologies are integrated.
DETAILED DESCRIPTION OF THE DRAWINGS In one embodiment, the present disclosure is directed to a method for facilitating accelerated network selection by a wireless UE device, comprising: prior to performing a full band scan, interrogating a list of networks with which the wireless UE device has registered at least once in a given period of time; determining a network availability likelihood score associated with each of the list of networks; and selecting a network from the list of networks based on its network availability likelihood score.
In another embodiment, the present disclosure is directed to a method of assigning values to networks in a list of networks operable for connecting a wireless UE device, comprising: determining an array of data values corresponding to at least one prior connection attempt of the wireless UE device to a particular network, if the wireless UE device has previously attempted to connect to the particular network; and determining a network availability likelihood score for the particular network based upon the array of data values. It will be realized by one of ordinary skill in the art that an �array� as used herein merely refers to a list of elements, either in one-dimensional form (e.g., a vector) or in multidimensional form. Accordingly, where provided in a vector form, it should be understood that a data vector does not refer to any physical/spatial quantity having a magnitude and direction in conventional sense.
An apparatus and method of the present patent disclosure will now be described with reference to various examples of how the embodiments can best be made and used. Like reference numerals are used throughout the description and several views of the drawings to indicate like or corresponding parts, wherein the various elements are not necessarily drawn to scale. Referring now to the drawings, and more particularly to FIG. 1, depicted therein is an exemplary generalized radio network environment 100 wherein one or more embodiments of the present patent disclosure may be practiced when a wireless user equipment (UE) device relocates to a new geographic area having the exemplary radio environment. For purposes of the teachings herein, a generalized wireless UE device 102 is deemed to be a mobile equipment (ME) device having a removable storage module, and may comprise any portable computer (e.g., laptops, palmtops, or handheld computing devices) or a mobile communications device (e.g., cellular phones or data-enabled handheld devices capable of receiving and sending messages, web browsing, et cetera), or any enhanced personal digital assistant (PDA) device or integrated information appliance capable of email, video mail, Internet access, corporate data access, messaging, calendaring and scheduling, information management, and the like, that is preferably operable in one or more modes of operation and in a number of frequency bands and/or radio access technologies (RATs). For example, UE device 102 may operate in the cellular telephony band frequencies such as 450 MHz, 700 MHz, 900 MHz, 1800 MHz, 1900 MHz, and 2.4 GHz, etc., as well as Wireless Local Area Network (WLAN) bands. Further, other bands in which the UE device could operate wirelessly may comprise Wi-Max bands or one or more satellite bands. Accordingly, for purposes of the present patent disclosure, those skilled in the art should recognize that the term �UE device� or �wireless device� may comprise a ME device (with or without any removable storage module such as a USIM/RUIM/SIM card, or a compact Flash card, SD card, etc.) as well as other portable wireless information appliances, also with or without such storage modules.
Further, UE device 102 is operable to obtain service from an access network (AN) space 106 that is connected to the WACN space 104. In one implementation, the AN space 106 includes one or more generic access networks (GANs) 118 as well as any type of wireless LAN (WLAN) arrangements 120, both of which may be generalized as any wireless AN that is operable to provide access services between UE device 102 and a PLMN core network using a broadband Internet Protocol (IP)-based network. WLAN arrangements 120 provide short-range wireless connectivity to UE device 102 via access points (APs) or �hot spots,� and can be implemented using a variety of standards, e.g., IEEE 802.11b, IEEE 802.11a, IEEE 802.11g, IEEE 802.11n, HiperLan and HiperLan II standards, Wi-Max standard (IEEE 802.16 and IEEE 802.16e), OpenAir standard, and the Bluetooth standard (IEEE 802.15), and the like.
Where CDMA networks are exemplified for use by a UE device, such networks may be identified by System Identifiers (SIDs) and Network Identifiers (NIDs), where a SID typically covers the area of a city or large town although there are no strict guidelines or requirements for the size of SIDs. Accordingly, the definition of each CDMA network may be determined by individual operators and/or national regulatory bodies. A �NID� is an optional subdivision of a SID, where a NID can identify, e.g., different rating areas, toll areas, private networks, MSC boundaries, or any other subdivision that an operator may want to distinguish within a SID. A national operator may have coverage over an entire country, where for certain countries, this can amount to tens and sometimes hundreds of cities/regions being covered.
If the list of networks is not indexed, then the UE device 102 may search through the list of networks to find a network whose network availability likelihood score indicates a greater likelihood of network availability than any other network of the list of networks. The UE device 102 may select a �most likely� network, and then may select a different network of the list of networks if the list of networks has more than one network and if the different network has a network availability likelihood score indicating a greater likelihood of being available. Since the list of networks may have only a few networks therein, and since the processing speed of the UE device 102 can be significant, a network of the list of networks can be selected promptly.
While updating the data arrays may be performed without significant computation, and while updating the network availability likelihood score for a network may be performed in response to the data arrays, updating the weighting factors may be more involved, and may include adjusting the means, modules and/or methods by which the network availability likelihood score is updated. Accordingly, updating the weighting factors may provide �feedback� to the updating of the network availability likelihood score.
FIGS. 3-6 depict exemplary database embodiments, e.g., tables, that include a Last Recent PLMNs list structure as well as certain channel frequency coding schema according to the teachings of the present disclosure. Table 300 of FIG. 3 may include a data array for each network of the list of networks. For example, in a first row, table 300 may include a data array or data vector pertaining to a network identified by a network IDa 302. The first row array may also include a channel and/or frequency band(s) 304 on which the UE device was last camped as well as a network time stamp 306 and a total time on network value 308. Other rows of the table of FIG. 3 may include other data arrays pertaining to other networks, e.g., IDb 310 and IDc 312, and may also include networks available nearby (i.e., �neighbor frequencies�).
Table 500 depicted in FIG. 5 may allow further expansion of the table depicted in FIG. 4, which may be useful when a tag �A0� is present within a GSM block of data. Similarly, table 600 depicted in FIG. 6 may allow further expansion of the table depicted in FIG. 4, which may be useful when a tag �A1� is present within an FDD block of data. Although not shown, a similar table may also allow further expansion of the table depicted in FIG. 4, which may be useful when a tag �A2� is present within a TDD block of data.
