Description

    CROSS-REFERENCE TO RELATED APPLICATION(S)
  • This application discloses subject matter related to the subject matter disclosed in the following commonly owned co-pending U.S. patent application(s): “NETWORK SELECTION SCHEME USING A ROAMING BROKER (RB),” filed even date herewith, in the name(s) of: Adrian Buckley, Paul Carpenter, Nicholas P. Alfano, and Andrew Allen (Attorney Docket No. 1400-1037US); each of which is hereby incorporated by reference in their entirety.

  • DETAILED DESCRIPTION OF THE DRAWINGS
  • A scheme is provided for acquiring network advertisement information in a network environment having one or more radio access networks (RANs), one or more core networks (CNs) and one or more service networks (SNs). A combination of codes is provided to a wireless user equipment (UE) device for facilitating discovery of applicable RAN-CN-SN combinations and subsequent network selection by the UE device.
  • In one embodiment, the present disclosure is directed to a network advertisement method operable in a network environment having one or more RANs, one or more CNs and one or more SNs, comprising: broadcasting an advertisement message by each RAN on a broadcast control channel associated therewith, the advertisement message including a combination of identification codes, wherein each combination comprises (i) an identification code associated with each particular RAN available to the wireless UE device, (ii) an identification code associated with a CN that is supported by the particular RAN, and (iii) an identification code associated with an SN that is supported by a particular CN; and receiving each advertisement message by a wireless UE device in a scanning procedure for facilitating network selection based at least in part upon the combination of identification codes.
  • In another embodiment, the present disclosure is directed to a network advertisement system operable in a network environment having one or more RANs, one or more CNs, and one or more SNs, comprising: means associated with each RAN for broadcasting an advertisement message on a broadcast control channel for reception by a wireless UE device; and means for including in the advertisement message a combination of identification codes, wherein each combination comprises (i) an identification code associated with each particular RAN available to the wireless UE device, (ii) an identification code associated with a CN that is supported by the particular RAN, and (iii) an identification code associated with an SN that is supported by a particular CN.
  • In a still further embodiment, the present disclosure is directed to a method of acquiring network advertisement information in a network environment, comprising: scanning by a wireless UE device in a frequency band for discovering available radio access networks; upon selecting a particular RAN, authenticating by the wireless UE device with an authentication server; upon successful authentication, obtaining an Internet Protocol (IP) address of a network advertisement broker (NAB) from a domain name server (DNS); contacting the NAB by the wireless UE device using the IP address; and obtaining network advertisement information from the NAB.
  • In yet another embodiment, the present disclosure is directed to a system for acquiring network advertisement information in a network environment, comprising: means associated with a wireless UE device for scanning in a frequency band for discovering available radio access networks; means for authenticating the wireless UE device with an authentication server; means, operable responsive to successful authentication of the wireless UE device, for obtaining an IP address of a NAB from a DNS; and means associated with the wireless UE equipment for contacting the NAB using the IP address and obtaining network advertisement information from the NAB.
  • A system 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 network environment 100 wherein an embodiment of the present patent disclosure may be practiced. A user equipment (UE) device 102 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. For example, UE device 102 may operate in the cellular telephony band frequencies 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. By way of illustration, the network environment 100 is envisioned as two broad categories of communication spaces capable of providing service to UE device 102 wherein acquisition of network advertisement information may be accomplished in accordance with the teachings set forth herein. In wide area cellular network (WACN) space 104, there may exist any number of Public Land Mobile Networks (PLMNs) that are operable to provide cellular telephony services which may or may not include packet-switched data services. Depending on the coverage area(s) and whether the user is roaming, WACN space 104 can include a number of home networks 110 (i.e., home PLMNs or HPLMNs, or equivalent HPLMNs or EHPLMNs), visited networks (i.e., VPLMNs) 112, each with appropriate infrastructure such as Home Location Register (HLR) nodes 115, Mobile Switching Center (MSC) nodes 116, and the like. Since the WACN space 104 may also include a General Packet Radio Service (GPRS) network that provides a packet radio access for mobile devices using the cellular infrastructure of a Global System for Mobile Communications (GSM)-based carrier network, a Serving GPRS Support Node (SGSN) 114 is exemplified therein. Additionally, by way of generalization, the PLMNs of the WACN space 104 may comprise radio access and core networks selected from the group comprising Enhanced Data Rates for GSM Evolution (EDGE) networks, Integrated Digital Enhanced Networks (IDENs), Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Universal Mobile Telecommunications System (UMTS) networks, or any 3rd Generation Partnership Project (3GPP)-compliant network (e.g., 3GPP or 3GPP2), all operating with well known frequency bandwidths and protocols.
  • 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, HiperLan and HiperLan II standards, Wi-Max standard, OpenAir standard, and the Bluetooth standard.
  • In one embodiment, interfacing between the WACN and AN spaces may be effectuated in accordance with certain standards. For instance, GAN 118 may be interfaced with one or more PLMNs using the procedures set forth in the 3GPP TR 43.901 and 3GPP TS 43.xxx documents as well as related documentation. Likewise, WLAN 120 may be interfaced with at least one PLMN core using the procedures set forth in the 3GPP TS 22.234, 3GPP TS 23.234 and 3GPP TS 24.234 documents as well as related documentation, and may therefore be referred to as an Interworking WLAN (I-WLAN) arrangement.
  • Based on the foregoing, it should be recognized that the service infrastructure of the network environment 100 may be generalized into three broad segments: one or more radio access network (RANs) (which can include cellular band technologies as well as WLAN technologies), one or more core networks (CNs), and one or more service network (SNs). Depending on network ownership arrangements and service-level agreements, each RAN may support one or more CNs, each of which in turn may support one or more SNs. Such combinations of infrastructure equipment across multiple owners are sometimes used to create Mobile Virtual Network Operators (MVNOs). The teachings of the present patent disclosure are equally applicable to MVNOs as to PLMNs. Since each RAN, CN, or SN may be provided with its own network identifier (ID code), and further because of the numerous RAN-CN-SN combinations available in the network environment 100, traditional broadcasting of a single broadcast identifier for providing network advertisement information becomes unworkable.
  • To formalize the teachings of the present disclosure, reference is now taken to FIG. 2 wherein an exemplary embodiment of a network environment 200 is shown that is a more concrete subset of the generalized network environment 100 illustrated in FIG. 1. As depicted, wireless UE device 102 is operably disposed for acquiring network advertisement information from a RAN segment 202 that is coupled to a CN segment 204 which in turn is coupled to an SN segment 206. Three RANs are illustrative: RAN-1 208-1, RAN-2 208-2 and RAN-3 208-3, which are identified with the network codes MANC1, MANC2 and MANC3, respectively. The CN segment 204 is also illustrated with three CNs: CN-1 210-1 (having an ID code of MCNC1), CN-2 210-2 (having an ID code of MCNC2) and CN-3 210-3 (having an ID code of MCNC3). Likewise, the SN segment 206 is illustrated with SN-1 212-1 (having an ID code of MSNC1), SN-2 212-2 (having an ID code of MSNC2) and SN-3 212-3 (having an ID code of MSNC3).
  • By way of example, RAN-1 208-1 is operable to support connectivity to two CNs, CN-1 210-1 and CN-2 210-2. In similar fashion, RAN-2 208-2 supports three CNs and RAN-3 208-3 supports only one CN. Each CN supports connectivity to one or more SNs: e.g., CN-3 210-3 connects to SN-2 212-2 as well as SN-3 212-3. Given the interconnectivity of the RAN/CN/SN segments, several combinations of identification codes may be obtained for purposes of uniquely identifying the various RAN-CN-SN combinations that the wireless UE device 102 can potentially discover and select from. For instance, with a suitable Mobile Country Code (MCC) being included, the three ID code combinations associated with RAN-1 208-1 are:
      • [MCC.MANC1.MCNC1.MSNC1];
      • [MCC.MANC1.MCNC1.MSNC2]; and
      • [MCC.MANC1.MCNC2.MSNC2].
  • Likewise, the ID code combinations associated with RAN-2 208-2 are:
      • [MCC.MANC2.MCNC1.MSNC1];
      • [MCC.MANC2.MCNC1.MSNC2];
      • [MCC.MANC2.MCNC2.MSNC2];
      • [MCC.MANC2.MCNC3.MSNC2]; and
      • [MCC.MANC2.MCNC3.MSNC3].
  • The two ID code combinations associated with RAN-3 208-3 are: [MCC.MANC3.MCNC3.MSNC2] and [MCC.MANC3.MCNC3.MSNC2]. As will be described in detail hereinbelow, a number of options are available for providing the applicable network ID code information to the UE device 102 either in an initial scan procedure (i.e., when the device is not registered on any networks) or in a background scan procedure (i.e. when the device is registered on a network).
  • Further, a network advertisement broker (NAB) entity 214 is disposed in the network environment 200 that is operable as a depository of various RAN-CN-SN ID code combinations as well as information relating to supported services, capabilities, et cetera, on a network-by-network basis. For instance, a database structure associated with NAB 214 can contain RAN IDs, CN IDs to which each RAN is connected, services supported by each RAN, other access networks supported or operated by a RAN (which could be any radio technology such as 3GPP, 3GPP2, or any IEEE-based WLAN, as alluded to in the foregoing discussion), and the like, any or all of which information may be updated periodically or as needed. Additionally, depending on implementation, NAB 214 may be associated with a RAN, a CN, or an SN, or in any combination thereof. In a still further embodiment, NAB 214 may be provided as a third-party entity accessible via a public packet-switched Internet Protocol (IP) network 216, e.g., the Internet.
  • Referring now to FIG. 3, depicted therein is an exemplary database structure 300 provided as part of a network advertisement broker (NAB) in accordance with the teachings of the present patent disclosure. Based on the scope of coverage of the database as well as any third-party commercial arrangements, the database structure 300 may be provisioned with the data pertaining to a fairly large number of RANs. Reference numeral 302 refers to one or more RANs identified by their RAN ID codes. Services supported by each RAN are identified in column 304. For example, RAN-1 is operable to support High Speed Datalink Packet Access (HSDPA), EDGE, and the like. Cross-relationship or interoperability of a particular RAN with other access networks is indicated in column 306. As illustrated, RAN-1 interoperates with additional RANs, RAN-X, RAN-Y, and RAN-Z, as well as WLANs, WLAN-A and WLAN-C. Reference numeral 308 refers to the core networks supported by each particular RAN identified in column 302. Reference numeral 310 refers to the various services supported by each CN, such as, e.g., IP Multimedia Subsystem (IMS), Presence, Push-to-Talk over Cellular (PoC), and the like.
  • In accordance with the teachings of the present patent disclosure, at least three options are available for providing network advertisement information (i.e., information indicating which networks and network combinations are available to a wireless device):
      • Broadcast on a per RAN basis. In this option, existing broadcast messages may be expanded or additional broadcast messages be created to carry the combinations of network ID codes.
      • Broadcast all available networks and network combinations via a beacon channel which may be provided by a third-party, e.g., a public body, a consumer group, etc.
      • Provided via querying a NAB entity.
  • FIG. 4 depicts an exemplary message flow diagram of the present patent disclosure for acquiring network advertisement information according to one embodiment where advertisement messages are broadcast from RANs. One or more RANs 404 are operable to broadcast information via associated control channels over the air interface 402. In one arrangement, the RAN nodes 404 may comprise Base Transceiver Station (BTS) nodes deployed in various cellular networks. Reference numerals 406-1 through 406-N refer to the control channel messages that are broadcast by the network nodes at a designated repetition rate. In one implementation, the broadcast information may include network ID code combination information, capability information, adjacent cell information, among other types of information. UE 102 is operable to read the broadcast information over the air interface 402 and based at least in part upon the received advertisement information, appropriate network selection may be carried out which may be mediated through application of such preferences and prohibitions as may be configured by the subscriber, network operators, and the like.
  • In one implementation, the various RAN-CN-SN ID code combinations may be transmitted in their entirety. That is, each RAN-CN-SN ID code combination is completely resolved and transmitted explicitly. For example, each of the three combinations [MCC.MANC1.MCNC1.MSNC1]; [MCC.MANC1.MCNC1.MSNC2]; and [MCC.MANC1.MCNC2.MSNC2] provided in association with RAN-1 of FIG. 2 may be broadcast by RAN-1 in complete form. In another implementation, each CN may advertise all SN ID codes it supports. For instance, the [MCC.MANC1.MCNC1.MSNC1:MSNC2] combination format indicates that both MSNC1 and MSNC2 are supported by the CN identified by MCNC1.
  • As alluded to before, for each network there is a corresponding broadcast message that defines the services that are available. In one aspect, UE 102 can also request the services information by transmitting a particular ID code combination (e.g., [MCC.MANC1.MCNC1.MSNC2]) to the appropriate network node to obtain such information. Additionally, the ID code information as well as the services information may be provided to the individual RANs by one or more NABs for broadcasting.
  • FIG. 5 depicts an exemplary message flow diagram of the present patent disclosure for acquiring network advertisement information according to another embodiment. As before, UE 102 is operable to read broadcast messages over the air interface 402 from the individual RANs. Using such applicable selection filters (e.g., positive filters (i.e., preferences) as well as negative filters (i.e., prohibitions)) as may be configured on the device, a particular RAN may be selected (block 506). Thereafter, the device/user is authenticated by engaging in an authentication mechanism 508 with an Authentication, Authorization and Accounting (AAA) server 504. Upon successful authentication, the RAN is operable to permit the device to contact a suitable NAB, e.g., NAB 214, using the NAB's IP address. In one implementation, the IP address may be obtained via a Fully Qualified Domain Name (FQDN) query initiated by the device, wherein the FQDN is constructed using the RAN's a Mobile Country Code (MCC) and Mobile Network Code (MNC). In another implementation, the AAA server 504 may provide the IP address or FQDN. Reference numerals 510 and 512 refer to a IP address request via FQDN query to a domain name server (DNS) 502 and the response therefrom. Once the NAB's IP address is available to UE device 102, it then contacts NAB 214 via a request message 514 and obtains the requisite NAB information via a reply 516. As part the request message 514, UE device 102 may include any or all of the following data: subscriber ID (e.g., International Mobile Subscriber Identity (IMSI) which is constructed as [MCC] [MNC] [MIN] in GSM, where [MCC] identifies the country that the subscriber is from, [MNC] identifies the PLMN network, and [MIN] is the unique ID that identifies the wireless UE device), network ID, (e.g., Cell Global Identification (CGI) or System Identification (SID)), network IDs of other networks, location information of the wireless UE device (e.g., Global Positioning System or GPS coordinates), media access control (MAC) addresses of available access points, and MAC address of the wireless UE device.
  • As part of the reply message 516, NAB 214 is operable to transmit the stored RAN-CN-SN ID information as well as the services and capabilities associated therewith. Based on the geographic location information of the wireless UE device, the NAB information may be appropriately customized. Upon receipt of the requisite information, the wireless UE device 102 may store it locally.
  • FIG. 6 is a flowchart associated with an embodiment of the method described hereinabove. At block 602, the wireless UE device is operable to scan for available RANs including WLANs in one or more frequency bands and in one or more radio access technologies, depending on the device configuration, et cetera. For example, it is possible to configure the wireless UE device for a number of technology modes that are used, wherein the configuration information may be stored as an elementary file (EF) structure on a Subscriber Identity Module (SIM) card or Removable User Identity Module (RUIM) card operable with the device. Other removable memory forms may include compact Flash, secure SD, et cetera. In another embodiment, such data could be stored in a fixed memory module integrated with the device and/or as part of a managed object information tree. Additionally, the device configuration data may be modified by the network operator via an Over the Air (OTA) mechanism such as Short Message Service (SMS), Cell Broadcast, Multimedia Broadcast/Multicast Service (MBMS), or Unstructured Supplementary Service Data (USSD). In a still further embodiment, it may be possible for the subscriber to modify the device configuration data.
  • Given the diversity of the exemplary network environment 100 described earlier with respect to FIG. 1, it is envisaged that scanning may be effectuated in a frequency band in which at least one of the following technologies is operating: GERAN (without EDGE), GERAN (with EDGE), an IDEN network, a CDMA/CDMA2000/TDMA network, a UMTS network, and so on. Additionally, scanning may be effectuated in a frequency band compliant with a WLAN standard selected from: IEEE 802.11b standard, IEEE 802.11a standard, IEEE 802.11g standard, HiperLan standard, HiperLan II standard, Wi-Max standard, OpenAir standard, and Bluetooth standard. Further, the UE device includes logic for selecting a RAN based at least in part upon the network information obtained via scanning. Thereafter, an authentication mechanism using AAA is employed for authenticating the device and subscriber (block 604). The IP address of suitable NAB is obtained using, e.g., FQDN (block 606). Subsequently, the NAB is contacted using the IP address obtained in block 606, whereupon appropriate network advertisement information including services/capabilities information may be obtained from the NAB. As alluded to previously, such information may be customized based on the geographic location of the device, for example. These operations are illustrated in blocks 608 and 610.
  • FIG. 7 depicts an exemplary database structure 700 that may be provided as an operated-based list, a user-based list or an enterprise-based list, or any combination thereof, for configurably setting network selection preferences and prohibitions according to one aspect of the present patent disclosure. In one embodiment, the database structure 700 is configured as an operator-defined network list that specifies a plurality of network IDs which should be considered as preferred networks in one or more radio access technologies, wherein the network IDs are populated by the operator. In another embodiment, the database structure 700 may be configured as one or more user network lists, with one list per user using the wireless UE device, for example. Each such list may be accessed by the users upon identifying themselves to the device, wherein the contents of the list (i.e., network IDs) are populated by the respective users. In yet another embodiment, the database structure 700 may be configured as a list of network IDs that are preferred by an enterprise owning the wireless devices for the benefit of its employee-users.
  • Irrespective of the particular configuration, the database structure 700 defines a plurality of radio access technologies, e.g., EDGE technology 702A, WLAN technology 702B, and UMTS technology 702C, wherein a number of RAN IDs are provided for each technology. As illustrated in FIG. 7, column 704A identifies multiple RAN IDs for the EDGE technology, each RAN supporting one or more core networks identified in corresponding column 706A. Likewise columns 704B/706B and columns 704C/706C are provided for the WLAN and UMTS technologies respectively. As one skilled in the art may appreciate, the various IDs can be Service Set IDs (SSIDs) (for WLAN), SIDs (for IS-95 and IS-136), or [MCC,MNC] combinations (for GSM).
  • Similar to the network preference lists set forth above, an analogous database structure may be provided that identifies one or more networks that are forbidden for use. Such a list of prohibited networks may be configured as, for example, an operator-barred RAN list (i.e., specified by an operator), enterprise-barred RAN list (i.e., specified by an enterprise), operator-barred CN list (i.e., specified by an operator), and enterprise-barred CN list (i.e., specified by an enterprise).
  • In addition to one or more of the embodiments and configurations of the database structures identifying network preferences and prohibitions, one or more home network lists (including equivalent home networks) may be provided for facilitating network selection in conjunction with a network entity referred to as a roaming broker (RB). Additional details regarding RB provisioning and its interaction with a NAB may be found in the following commonly owned co-pending U.S. patent application entitled “NETWORK SELECTION SCHEME USING A ROAMING BROKER (RB),” filed even date herewith (Attorney Docket No. 1400-1037US) and cross-referenced hereinabove.
  • Given that there are a number of lists that could be used in the radio part, appropriate intelligence or logic may be provided as part of the wireless UE device in order to resolve priority among various radio access technologies, preferences and prohibitions. Where the wireless device is operable in multiple modes (i.e., different technologies), a particular mode may be designated as its primary operating mode (highest priority). Secondary and tertiary operating modes may be accorded lower priorities accordingly. Again, it is envisaged that the operating modes may be configured or reconfigured dynamically, based on operator-defined criteria, subscriber-defined criteria, or enterprise-defined criteria. Some exemplary parameters used in controlling the operating mode may be: device location information (e.g., GPS information), SSIDs, SIDs, [MCC,MNC] combinations, cell IDs, and the like. Additionally, certain override criteria may be provided for operators, enterprises or subscribers (i.e., for hard set). In one implementation, the interaction of these parameters defines when a particular technology takes either primary, secondary, or tertiary operating mode. Each defined parameter may be provisioned with a flag associated therewith, indicating whether the defined condition has to occur in order to set an operating mode. For example, consider that the wireless UE device discovers a specific cell ID upon performing an initial scan. It is assumed that the subscriber has defined the condition that if a home SSID is found in this cell, WLAN is to be set as the primary operating mode. Accordingly, the device's primary mode would be set to WLAN in this particular cell provided the home SSID has been found, and the secondary mode may be set to GSM.
  • As pointed out earlier, the provisioning of various preferred and barred network lists necessitates appropriate device logic for specifying the order in which to use them. Moreover, each country may have its own regulatory requirements as to which list should take precedence. An enterprise company for instance may forbid access to a public WLAN access point that operates in the vicinity of the company's premises. Additionally, certain device logic may be necessary for specifying the scanning behavior as well, since there may be a number of bands on per-technology basis in which the device is capable of scanning. FIGS. 8A-8C depict exemplary database structures or logic for facilitating configuration of the operation of a wireless UE device. In particular, reference numeral 800A of FIG. 8A refers to a list ordering scheme operable with the device wherein a priority is imposed on the device's various network lists. In FIG. 8B, reference numeral 800B refers to a scheme for specifying initial scan behavior of the device. As illustrated, when the device performs an initial scan, it is provided that Technology A should be scanned in bands A, B, and C.
