Description

SELECTION OF NETWORK WHEN MULTIPLE NETWORKS ARE AVAILABLE IN A COVERAGE AREA FIELD OF DESCRIPTION The present description relates generally to communication networks. More particularly, and not by way of limitation, the present patent application is directed to a scheme for network selection when several networks are available in a coverage area. BACKGROUND When deploying a wireless network, there is a need to transmit an identifier such that a wireless user equipment device (UE) desiring service can identify the wireless network. In a typical implementation, the name of the network may be displayed to the user in accordance with known cellular telephone standards. If several networks have the same name because they are equivalent, only that name is shown to the user, thus denying any control by the user in the selection of the network. Additionally, this aspect is particularly disadvantageous when multiple networks have different capabilities. SUMMARY OF THE INVENTION In one embodiment, a network selection scheme is provided by a UE wireless device that is operable to discover multiple Public Land Mobile Networks (PLMN) available in a location area. Each discovered PLMN is identified and a clue associated with the PLMN is presented to the user in such a way that he can select a particular PLMN. In one aspect, a selection method is set forth which covers: Identifying a list of available PLMNs discovered through the scanning of an UE device in a location area; present a user with a clue associated with each of the available PLMNs; and the selection of a particular PLMN by the user based at least in part on the indico to register there. In a following aspect, a UE device is set forth to encompass: A communication subsystem including an operable transmitter-receiver module for scanning a cellular band to discover available PLMNs in a location area; an operable logical module to identify a list of available PLMN discovered by scanning the cellular band; and a logic module for presenting a user with a clue associated with each of the PLMNs, wherein the user can select a particular PLMN based at least in part on the clue.

DETAILED DESCRIPTION OF THE DRAWINGS A system and method of the present patent description will be described below with reference to several examples of how the modalities can be made and used. As a numerical reference it is used throughout the description and several views of the drawings to indicate corresponding or similar parts, where the various elements are not necessarily drawn to scale. Referring now to the drawings, and more particularly to FIGURE 1, there is shown a generalized exemplary network 100 wherein one embodiment of the present patent description can be practiced. A user equipment device (UE) 102 may encompass any portable computer (e.g., laptops, handheld computers, or hand-held computing devices) or a mobile communications device (e.g., cell phones or handheld computers capable of receiving and send messages, explorers.

Internet, etc.), or any specialized personal assistant (PDA) or integrated information application with email capability, email with video, access to the Internet, access to corporate data, send messages, schedule schedules and calendars, information management, and similar that is preferably operable in one or more modes of operation in a number of frequency bands. For example, the UE device 102 can operate in a cellular frequency band as well as in local wireless network (WLAN) bands, other bands in which the UE device can operate wirelessly can include Wi-Max bands or one or more satellite bands. As an illustration, the network environment 100 is comprised of two broad categories of communication spaces capable of providing service to a device 102 where access to a public mobile land network (PMLN) can be achieved in accordance with the teachings that continue here. In the wide area cellular network space (WACN) 104, there may be any number of PLMN that are operable to provide cellular telephone services that may or may not include data services activated per packet. Depending on the area or coverage areas and whether the user makes use of the spatial search, the WACN space 104 may include a number of local network 110 telephones (e.g., home PLMN or HPLMN, or equivalent HPLMN or EHPLMN) , visited networks (for example: VPLMN) 112, each with appropriate infrastructure such as home location registration nodes (HLR) 115, central exchange center (MSC) nodes 116, and the like. Since the WACN 104 space can include a general radio service packet network (GPRS) that provides packet radio access for mobile devices using cellular infrastructure of a network based on a global communication system for mobile communication (GSM), a GPRS service support node 114 is exemplified there. Additionally, as a generalization, the PLMN of the WACN space 104 may include networks selected from the group of the network consisting of special information ranges for evolution GSM (EDGE), a special integrated digital network (IDEN), an access code division network Multiple network (CDMA), a multiple access time division network (TDMA), a universal telecommunications system network (UMTS), or any third-generation Community (3GPP) project type network (for example: 3GPP or 3GPP2), all operating with bandwidth and well-known frequency protocols. In addition, the UE device 102 is operable to obtain service from an access network space (AN) 106 connected to the WACN space 104. In one implementation, the AN space 106 includes one or more generic access networks (GAN) 118 as well as any type of wireless LAN (WLAN) 120 arrangements, both of which can be generalized as any AN that serves to provide access services between an UE 102 device and a PLMN core network using a network based on Internet protocol (IP) broadband. WLAN arrays 120 provide ortho-range wireless connectivity to the UE 102 device via access points (APs) or "hot spots" and can be implemented using a variety of standards for example IEEE 802.11b, IEEE 802.11a, IEEE 802 standards . llg, HiperLan and HiperLan II, Wi-Max, OpenAir and Bluetooth. In one embodiment, the interfaces between the WACN and AN spaces can be made according to certain standards. For example, GAN 118 can interface one or more PLMNs using the procedures described in documents 3GPP TR 43.901 and 3GPP TS 43. XXX as well as the related documentation. Similarly, WLAN 120 may interface with at least one PLMN core using the procedures indicated in the 3GPP TS 22.234, 3GPP TS 23.234 and 3GPP TS 24.234 documents as well as the related documents, and can therefore be called an interactive WLAN array (I -WLAN). For this purpose of the present description, those standards are incorporated as a reference where applicable. Since the mosaic of the environment of the network 100 in which the UE 102 device can be placed, it is desired that a mechanism exist in such a way that the user can select a particular PLMN from a PLMN host that can be discovered in a location area by scanning the cell bands or in WLAN bands. It would be further advantageous to uniquely identify multiple EHPLMNs in such a way that the user can specify a particular network for the service. In order to formalize the teachings of the present disclosure, reference is now made to Figure 2 when an exemplary embodiment of a network environment 200 is shown which is a specific subset of the generalized network environment 100 illustrated in Figure 1. As shown the wireless device UE 102 is operably arranged to discover a set of PLMNs that allow access by means of a conventional radio access network (RAN) infrastructure in addition to having connectivity to one or more accessible AN networks for the UE device 102. By way of example AN-1 2002-1 to 1N-N 2002- which are now generalized for the purposes of the present patent description to include any type of GAN, WLAN and / or I-WLAN arrangement (known or unknown), serve to provide access to one or more PLMN once they are discovered by the UE device. As illustrated a wireless AN can support connectivity to one or more PLMN, or none of them, which may include VPLMN 201-1 to 204. M as well as HPLMN (for example HPLMN 206) and one or more EHPLMN 208 with respect to to the UE device 102. Where the AN-PLMN connectivity is supported, which PLMN behind a particular AN are visible to the UE 102 device may depend on several commercial factors, for example the contractual arrangements between the AN operators and the PLMN operators. By way of illustration, AN-1 202-1 supports connectivity to VPLMN-1 204-1, VPLMN-1 204-2 and EHPLMN 208. Likewise AN-2002-1 supports connectivity to VPLMN-M 204-M as well as HPLMN 206 and EHPLMN 208. On the other hand, AN-N 202-N has no connectivity to wide area PLMNs. Furthermore, in addition to being able to access the different PLMNs by means of a wireless AN, UE 102 also serves to scan the cellular bands to directly discover the PLMNs. As is well known, each of the wide area cellular PLMN can be distributed in several cells (eg typically three sectors of 10 degrees per base station (BS) or cell). Each individual cell is provided with a Global Cell Identification parameter (CGI) to identify them. A group of cells is designated as a Localization Area (LA) and can be identified by means of an LA identifier (LAI). At a macro level, the PLMN can be identified according to the base cellular technology. For example GSM-based PLMN can be identified by means of an identifier consisting of a Mobile Country Code (MCC) and a mobile network code (MNC). The PLMAs based on CDMA / TDMA can be identified by means of a System Identification Parameter (SID) and / or a network identification parameter (NID). In spite of the cellular infrastructure, all the cells transmit the macro-level identifiers PLMN in such a way that a wireless device (for example an UE 102 device) that wishes to obtain the service can identify the wireless network. Additionally, a subscriber also receives a unique identifier that can vary depending on the base cellular infrastructure and can be constructed at least in part from some of the parametric ones that are used when building the network identifiers. In GSM, for example, an International Mobile Subscriber Identity (IMSI) parameter identifies only the subscriber and is constructed as [MCC] [MNC] [MIN], where [MCC] identifies the country where the subscriber is from, [MNC] ] identifies the PLMN network, and [MINI [] is the only ID that identifies the mobile unit (this is the UE wireless device) within the network. For purposes of illustration, the embodiments of the present disclosure will be particularly exemplified by reference to GSM networks, although it should be appreciated that the teachings herein shown can be applied mutatis mutandis in other cellular networks. Figures 3A and 3B show exemplary structures for databases, which may be provided with a UE device to facilitate the selection of the network according to a modality. The reference number 300A refers to the basic structure of the database consisting of a list of combinations [MCC] 302A and [MNC] 302B that can be identified as the same networks. In the case of equivalent networks, combinations [MCC] [MNC] can identify a series of EHPLMN for the IMSI associated with the subscriber. The reference numbers 304, 306 and 308 refer to three exemplary networks, where networks 304 and 406 share the same [MCC], that is [ABC] and networks 304 and 308 share the same [MCN] (this is [X AND Z] ) . In a modality and format, the data structure 300A can be stored as an elementary file structure (EF) in a subscriber identity module (SIM) card or a removable user identity module (RUIM) card that operates in a wireless UE device. In another embodiment, the data structure 300A could be stored in a memory module integrated in the wireless UE device. The reference number 300B refers to an improved database structure in which additional information can be provided to facilitate the selection of the network. A master column [MCC] [MNC] 320 identifies the combinations [MCC] and [MNC] to match the [MCC] / [MNC] part of the IMSI (this is a master local PLMN). A network name column 322 identifies the master network by name. A local network column (EHPLMN) 324 includes a list of local networks for each pair of [MCC] [MNC] masters. In an implementation the combinations [MCC] [MNC] that identify the local networks can be provided in a priority order. For example, a position priority can be implemented where a combination [MCC] [MNC] at the top has a higher priority than the one below, or a combination [MCC] [MNC] at the left has a higher priority over the one on the right. An explicit priority range can also be provided where an indicator indicating the priority of the PLMN is appended to the structure of the database 300B. For example, a value of [0] can indicate the highest priority. When there is no stored priority indicator, all PLMNs have equal priority. A cue column 325 is provided to uniquely identify each PLMN listed in the local network list 324. Where the cue may consist of a unique identity name which may include some reference to the master [MCC] [MNC] pair or the name of the associated network. Continuing with the reference to Figure 3B, the master combinations [MCC] [MNC] 304 and 308 are identified by the names ALPHA-CELLULAR 326 and BETA-CELLULAR 328, respectively. Three local networks are provided for the master mix [MCC] [MNC] 304: [MCCa, MNCa] 330-1, [MCCb, MNCb] 330-2, [MCCc, MNCc] 330-3, each of which is identified particularly with a name. In the same way, two networks are provided for the master combination [MCC] [MNC] 308: [MCCg, MNCg] 332-1 and [MCCh, MNCh] 332-2. As before, the structure of the data 300B may be provided as part of a storage module integrated with the wireless device UE. In one implementation, the wireless device UE operates by being energized to determine the capacity of the SIM / RUIM card that has been inserted. If the wireless device discovers that the SIM / RUIM card contains an EHPLMN list, the device uses the list for subsequent network selection operations. If the SIM / RUIM card does not contain a PLMN list, the wireless device serves to read the subscriber's IMSI. After this if the wireless device is provided with stored local network lists its memory for the [MCC] [MNC] pairs of the IMSI, the PLMN database can then be used to find the list of HPLMN associated with a particular IMSI. Otherwise, the UE wireless device serves to perform the network discovery procedure as currently specified. Figure 4 shows a flow chart of a modality of a network selection method. As illustrated, the wireless UE device serves to scan in one or more frequency bands it supports in a broadband scanning procedure to discover all available PLMNs in a location area where the device is placed (block 402). As alluded to above, some of the PLMNs can be discovered through the UE through an appropriate wireless AN scanning process that is performed in a frequency band that complies with a WLAN standard selected from the group consisting of: IEEE 802.11 standard b, HiperLan standard, HiperLan II standard, WI-Max standard, Open Air standard, and Bluetooth standard. By way of example, where the UE is capable of dual operation and when the UE finds a PLMN, it stores the identity of the network (for example a combination [MCC] [MNC]) in the memory or in the SIM card or RUIM associated with the user until they can no longer find PLMN. As another variation, in addition to storing the combinations [MCC, MNC] of all discovered PLMNs, the UE is capable of storing its a particular PLMN is suitable for GPRS or not, this capacity may be transmitted from the PLMN infrastructure. The UE serves to perform the network discovery procedures for WLAN as defined in the current 3GPP specifications TS 23234 and 3GPP TS 24,234 (incorporated by reference). If the WLAN finds a Service Group ID (SSID) that knows the HPPLMN, the UE authenticates with the WLAN using the Root Network Access Identifier (NAI). Otherwise the UE performs network discovery as specified in the 3GPP TS 23.234 and 3GPP TS 24.234 specifications. As another variation, in addition to the SSID lists defined in the 3GPP specifications for WLAN access, the extra SSID / PLMN lists and the associated filtering criteria can be stored in such a way that the UE not only knows the WLANs that support PLMN access. But a mechanism is provided to speed up network selection as well as optimize / adjust the user experience. By way of illustration, the following lists can be defined: - Preferred SSIDs controlled by the operator for WLAN access; - SSID controller by the user for access to WLAN; - SSIDs prohibited for WLAN access; Preferred PLMN controller by the operator for WLAN access; - PLMN controlled by user for WLAN access; - PLMN prohibited for WLAN access; where the priority of SSID and PLMN is dictated by its position in the list. After identifying a list of available PLMNs in the location area of the UE (block 404), a unique cue associated with each of the PLMNs is presented to the user by means of a screen (block 406). The only indication may include a reference, by name or otherwise, to the master HPLMN (identifying an equivalent HPLMN). Additionally, an indication based on the capacity can also be presented in some modalities.

After this the user can select a particular PLMN based at least partially on the indicia associated with the network to register it (block 408). If the user wishes to change the selected PLMN for any reason (insufficient signal strength, lack of IP capabilities, quality of service, etc.) (decision block 410), another PLMN can be selected from the list of available PLMNs (block 412) ). Otherwise, the user can proceed with the registration process of the previously selected PLMN (block 414). Figure 5 shows a flow diagram of an exemplary message with reference to the methodology indicated above. One or more network nodes 504 serve to disseminate the information through associated control channels through the air interface 502. In accordance with the teachings of the present patent specification, the network nodes 504 may consist of nodes of Base Transceiver Station (BTS) used in several cellular networks. The reference numbers 506-1 to 506-N refer to the control channel messages that are broadcast by the nodes of the network at a designated repetition rate. In one implementation the broadcast information may include network identity information, capacity information, adjacent cell information, among other types of information. The UE 102 serves to read the information broadcast through the air interface 502 and based on at least a part of the stored PLMN indices database, it shows the appropriate indications to the user that uniquely identifies each of the PLMN discovered (block 510). After selection of a particular network, UE 102 is capable of performing registration 512 with the selected network 514. Figure 6 shows a graphic representation of the availability of multiple PLMNs in an exemplary location area 600. Three networks are illustrated: PLMNa 602-1, PLMNb 602-2, PLMNc 602-3. Due to the overlap of network coverage, one or more multi-network coverage areas or MNCA are possible in the illustrated scenario. For example, MNCA 604-1 defines a coverage area where PLMNa and PLMNc are available. Similarly, MNCA 604-2 and MNCA 604-3 define a coverage area with combinations PLMNa / PLMNb and PLMNb / PLMNc, respectively. Also MNCA 606 defines a region where all three networks are available. When a UE describes multiple networks in the location area 600, each is shown to the user with a unique ID, even when the networks are EHPLMN. Below are some scenarios in which the network selection can be made according to the teachings of the present description. I. When the UE device discovers a PLMN that it can identify as a local network, two possible implementations arise. In the case in which the HPLMN, the device can present only the network ID (for example the combination [MCC] [MNC]) that is identified as the master HPLMN, or if it is stored on the device, the name / index which is associated with the ID network. In another implementation, additional identification or reference to the master network ID or its name may be attached. II. In a manual selection mode, when the UE discovers two or more PLMNs that it identifies having the same network name, then the device can show the user that two or more instances of the network are available. In the case of EHPLMN, identification can be resolved by attaching the master local network ID with some additional information in text or numeric form. III. In another implementation with respect to the case of multiple EHPLMNs, the wireless UE may display the master local network ID and proceed with one of the following actions: (a) The user of the device would select the master local network, the device performs the task to select a particular HPLMN with the highest priority in the list that is being used by the device; (b) The user of the device would select the master local network, the device performs the task to deselect the first HPLMN that is found; (c) The user of the device would select the master local network, a task performed by the device to select a particular HPLMN with the highest signal strength; (d) After selecting the master local network by the user, the device may select a particular HPLMN with the highest priority in the list that is being used by the device. If another scan is required by the device and subsequently the same or a subgroup of the PLMN is found, the device could select another network that may not necessarily be the HPLMN previously selected, and € After selecting the master local network by the user, the device can randomly select a particular HPLMN from the list. IV. When there are multiple combinations [MCC] [MNC] that have been provided with a unique network name, the wireless UE can display the name of the network for each combination including a suffix to indicate that they are different networks. Additionally, the capabilities of each network can be determined or displayed to the user. Figure 7 shows a block diagram of a modality of the wireless device UE 700 that serves to perform the network selection procedures indicated in accordance with the teachings of the present disclosure. Those skilled in the art will recognize after referencing that although the UE mode 102 may comprise an array similar to that shown in FIG. 7, there may be a number of variations and modifications in hardware, software or firmware, with respect to the different modules shown. Accordingly, the arrangement of Figure 7 should be taken in an illustrative non-limiting manner with respect to the embodiments of the present disclosure. A microprocessor 702 providing general control of UE 700 is operably coupled to a communication subsystem 704 that includes transmitter / receiver (transceiver) functionality to perform multimodal communications across a plurality of bands. By way of example, a broadband wireless Tx / Rx module 706 and a Tx / Rx module AN 708. Although not particularly shown, each Tx / Rx module may include other associated components such as one more local oscillator modules (LO ), RF switches, band pass filters, A / D and D / A converters, processing modules such as digital signal processors (DSP), local memory, etc. As will be apparent to those skilled in the field of communications, the particular design of the communication subsystem 704 may depend on the communications networks with which the UE is intended to operate. In one embodiment, communication subsystem 704 operates with both voice and data communications. The microprocessor 702 also interfaces with other device subsystems such as auxiliary inputs / outputs (1/0) 718, serial ports 720, screens 722, keypad 724, speaker 726, microphone 728, random access memory (RAM) 730, a short range communications subsystem 732, and other device subsystems generally labeled as reference number 733. To control access, a SIM / RUIM 734 interface is also provided in communication with the microprocessor 702. In one implementation, the SIM / RUIM interface 734 operates with a SIM / RUIM card having a number of key configurations 744 and other information 746 such as identification data and data related to the subscriber as well as one or more SSID / PLMN lists and filters described in detail above. The operating system software and other control software may be made in a constant storage module (this is a non-volatile storage) such as a flash memory 735. In one implementation, the flash memory 735 may be segregated in different areas, for example storage area for 736 computer programs as well as storage regions such as 737 device status, address book 739, or other personal information manager (PIM) data 741, and other data storage areas tagged with reference number 743. Additionally, logical discovery / network 740 systems may be provided as part of the of the persistent storage to execute the different procedures, the correlation techniques and the mechanisms of selection of means of presentation indicated in the previous sections. Associated here is a storage module 738 for storing the SSID / PLMN lists, selection / scanning filters, capacity indicators, etc., also described in detail above. It is believed that the operation and construction of the embodiments of the present patent application will be evident from the detailed description indicated above. While the exemplary embodiments shown and described have been characterized as preferred, it should be understood that different changes and modifications may be made without departing from the scope of the present invention indicated in the following claims.
