FIG. 12 depicts a block diagram of an embodiment of a UE device operable according to the teachings of the present patent disclosure.
The present patent disclosure is broadly directed to a scheme for providing operator-differentiated messaging to a UE device that is operable in wide area cellular network (WACN) bands as well as in wireless access network bands (e.g., GAN bands and/or UMA bands). A network node (e.g., a GAN controller (GANC) or a UMA network controller (UNC)) is equipped with logic for resolving service requirements as well as network information gathered by the UE device. Based thereon, a response message is transmitted to the UE device, the response message including supplementary fields for carrying operator-differentiated information in free-form text.
In one aspect, an embodiment of a network messaging method is disclosed which comprises: gathering network information by a UE device via scanning in at least one band; transmitting by the UE device at least one of the network information and a set of service requirements to a network node via a registration request message; and responsive to the registration request message, transmitting a response message by the network node to the UE device, the response message including operator-differentiated textual information.
In another aspect, an embodiment of a network messaging system is disclosed which comprises: means associated with a UE device for gathering network information via scanning in at least one band; means associated with the UE device for transmitting at least one of the network information and a set of service requirements to a network node via a registration request message; and means associated with the network node, responsive to the registration request message, for transmitting a response message to the UE device, the response message including operator-differentiated textual information.
In a still further aspect, an embodiment of a UE device is disclosed which comprises: a logic module for facilitating identification of a set of appropriate service requirements relative to operating the UE device; a communication subsystem for gathering network information via scanning in at least one band and for transmitting at least one of the gathered network information and the service requirements to a network node via a registration request message; and a logic module for processing operator-differentiated textual information received from the network node via a response message responsive to the registration request message.
In yet another aspect, an embodiment of a GANC node operable with a UE device disposed in a wireless environment is disclosed which comprises: means for receiving at least one of network information and a set of service requirements from the UE device via a registration request message; and means, operable responsive to the registration request message, for transmitting a response message to the UE device, the response message including operator-differentiated textual information.
With respect to operating in GAN-mode, the UE device is operable to provide a number of information elements to a GANC node with which it establishes initial connectivity. Preferably, as pointed out in the foregoing discussion, such information can include network information gathered via scanning in other bands or modes as well as service requirements. Referring to FIG. 7B in particular, upon successful registration a PLMN or failure to register on any PLMN (block 750), the UE device is operable to search for a GAN network (block 752), preferably according to applicable 3GPP specifications. Once a Uniform Resource Locator (URL) or IP address of a GANC node has been obtained (block 754), the UE device authenticates and registers with the GANC using, for instance, known Generic Access-Resource Control (GA-RC) REGISTER REQUEST messaging (block 756). In accordance with the discussion set forth in the foregoing sections, such a registration message to the GANC may include information elements pertaining to any of the following in any combination:
BCCH/PCCH information for available PLMNs. For instance, in one implementation, BCCH/PCCH information for all available PLMNs are included. In other implementations, BCCH/PCCH information for a portion of available PLMNs may be included.
Those skilled in the art should recognize upon reference hereto that additional operations and/or information elements may be involved if the registration processes take place after the initial network discovery and registration process by the UE device as set forth above. For instance, with respect to WACN space (e.g., GERAN), if the UE device receives a redirect message from a GANC node (which could be a separate message or part of a general redirect message, as will be set forth in further detail below), the UE device may deregister from the current serving GERAN VPLMN and attempt registration on the VPLMNs in a number of ways. By way of illustration, the VPLMNs may be provided by the GANC in some priority order that may be followed by the UE device. Alternatively, if no order has been provided, a VPLMN may be chosen from the supplied list at random. With respect to subsequent registrations in GAN space, if the UE device has been redirected to another VPLMN and registration with that new VPLMN is successful, the UE device may be required to reregister with the home GANC using the same GAN as before. Alternatively, the UE device may register with the GANC associated with the new VPLMN if that information has been made available by the redirecting GANC. In a still further variation, there may be no subsequent GANC registration pursuant to instructions from the GANC.
It should be apparent that the service logic is preferably operable to evaluate and resolve a number of service scenarios based on the combinations of service and feature requirements as well as the network information received from the UE device. Additional details and flowcharts regarding exemplary service scenarios may be found in one or more of the above-referenced U.S. provisional patent application(s) and nonprovisional patent application(s), which are incorporated by reference. Set forth below is a discussion on providing operator-differentiated messaging to a wireless UE device by a network server node in certain exemplary scenarios.
Referring now to FIG. 9, shown therein is a flowchart associated with a scheme for providing operator-differentiated messaging to a wireless UE device according to one implementation of the present disclosure. As illustrated in the flowchart, the implementation is exemplary of the scenario wherein only HPLMN services are requested by the UE device (block 902). If voice-only services (block 904) or voice-and-data services (block 906) are requested (which may be determined at least in part based on the working mode of the UE device or on the application(s) being used), the registered PLMN in the WACN space is considered acceptable (block 908). The UE device then registers with an access network server node (i.e., GANC or UNC, as the case may be) associated with the home network by means of a suitable registration request message (e.g., GA-RC REGISTER REQUEST) block 910). Upon registration, the UE device may be informed that HPLMN dialing is available. Additionally, the network server node is operable to provide messaging with respect to various operator-specific and/or subscriber-specific service information (e.g., applicability of international calling or long distance charges, location-specific information, calling plans and associated pricing information, other operator-differentiated indicators including free-form textual information, et cetera) to the UE device. Such response messaging may be effectuated via a suitable REGISTER ACCEPT message or via a Short Messaging Service (SMS) or Unstructured Supplementary Service Data (USSD) message. Further, the network server node may send an indication to the UE device that it is registered with a GANC/UNC node in the HPLMN (i.e., home GANC/UNC node). These various message responses and processes are set forth in block 912.
FIG. 10 depicts a flowchart associated with a scheme for providing operator-differentiated messaging to a wireless UE device according to another exemplary service scenario of the present disclosure. For purposes of illustration, an HPLMN GANC node is provided as the network server node that eventually resolves the various service and feature requirements as well as the network information gathered by a UE device. Upon receiving the pertinent information from the UE device (e.g., via a REGISTER REQUEST message, as alluded to previously), the GANC node may perform one or more database queries involving local and/or remote databases in order to evaluate roaming service agreements, service capabilities, address lookup, etc. (block 1002). If the VPLMN that the UE device is registered on is determined to have GAN connectivity (block 1004), then the HPLMN GANC is operable to send a redirect message to the UE device (e.g., a GA-RC REGISTER REDIRECT message) which contains the URL/IP address of the VPLMN GANC node (block 1006). On the other hand, where the registered VPLMN does not have GAN connectivity, the service logic is operable to determine whether there exist other PLMNs that support GANCs. If so, their URL/IP address information may also be determined by performing appropriate database queries. Additionally, such determinations may be evaluated responsive to other information such as the UE's location, existence of applicable service arrangements, etc. These determinations are consolidated in block 1008. In one embodiment, it may involve verifying that the cells identified in received broadcast information still include cells that are available for use. The VPLMNs that are still available after this initial investigation may optionally be sent to a roaming database to determine of a roaming agreement exists between the HPLMN and VPLMN(s). If a suitable roaming agreement exists, preferred PLMN information may also be returned to the HPLMN GANC. After these optional procedures, the service logic of the GANC may transmit the filtered VPLMN information to another database to determine the URLs/IP addresses of available GANCs. Where redirection is established to be appropriate, a suitable redirect message (e.g., a GA-RC REGISTER REDIRECT message) may be transmitted to the UE device which includes one or more URLs/IP addresses of GANCs associated with a plurality of available VPLMNs (block 1010). Otherwise, a response message may be provided to the UE device that indicates a number of options (block 1012). For example, the response message may include an indication that no GAN services are available to the UE device. Another indication may be that only home network services are available. Alternatively or additionally, the response message may also include one or more supplementary fields (e.g., free-form text fields) operable to indicate additional capabilities where applicable. By way of illustration, such fields may be used with respect to various operator-specific and/or subscriber-specific service information (e.g., applicability of international calling or long distance charges, location-specific information, and other operator-differentiated indicators including textual information, et cetera) as described above. Further, as before, such messaging may be effectuated via a suitable GA-RC REGISTER ACCEPT message or via an SMS or USSD message.
With respect to the general syntax of the redirect messages set forth above, one embodiment may include a list of PLMN Identities (e.g., {MCC, MNC} combinations) as well as supported services and/or features that may be mandatory or optional. In another embodiment, the redirect message may include a list of GANC addresses (i.e., URLs, IP addresses) as well as supported services and/or features. Additional details regarding the structure and syntax of redirect messaging as well as the usage and taxonomy of location information may be found in one or more provisional and nonprovisional patent application(s) cross-referenced hereinabove.
In the scenarios where a GA-RC REGISTER ACCEPT message may be employed (as described above with respect to the flowcharts of FIGS. 9 and 10), its content may include various standardized information elements such as, e.g., GA-RC protocol indicator, message identity, cell identity, location area identification, timer and band information, GAN Service Zone information, etc., in addition to any supplementary fields as alluded to in the foregoing description.
Referring now to FIG. 11, shown therein is a functional block diagram of an exemplary AN server node 1100, e.g., GANC/UNC node 1100 according to one embodiment. Those skilled in the art should appreciate that AN server node 1100 may be provided in any of the configurations depicted in FIGS. 5A and 5B described hereinabove. Regardless, AN server node 1100 includes appropriate network selection logic 1102 operable to perform one or more of the procedures set forth above with respect to resolving gathered network information and service/feature requirement information that is provided by a UE device. Accordingly, in one embodiment, suitable storage areas may be provided for storing service/feature requirements 1104 as well as gathered network information 1106. Database query logic 1108 is provided to facilitate database query and interrogation of local and/or remote databases, e.g., DB 1110-1 through DB 1110-N.
FIG. 12 depicts a block diagram of an embodiment of a UE device operable according to the teachings of the present patent disclosure. It will be recognized by those skilled in the art upon reference hereto that although an embodiment of UE 102 may comprise an arrangement similar to one shown in FIG. 12, there can be a number of variations and modifications, in hardware, software or firmware, with respect to the various modules depicted. Accordingly, the arrangement of FIG. 12 should be taken as illustrative rather than limiting with respect to the embodiments of the present patent disclosure. A microprocessor 1202 providing for the overall control of an embodiment of UE 102 is operably coupled to a communication subsystem 1204 which includes transmitter/receiver (transceiver) functionality for effectuating multi-mode communications over a plurality of bands. By way of example, a wide area wireless Tx/Rx module 1206, a GAN Tx/Rx module 1208 and an I-WLAN Tx/Rx module 1210 are illustrated. Although not particularly shown, each Tx/Rx module may include other associated components such as one or more local oscillator (LO) modules, RF switches, RF bandpass filters, A/D and D/A converters, processing modules such as digital signal processors (DSPs), local memory, etc. As will be apparent to those skilled in the field of communications, the particular design of the communication subsystem 1204 may be dependent upon the communications networks with which the UE device is intended to operate. In one embodiment, the communication subsystem 1204 is operable with both voice and data communications.
Microprocessor 1202 also interfaces with further device subsystems such as auxiliary input/output (I/O) 1218, serial port 1220, display 1222, keyboard 1224, speaker 1226, microphone 1228, random access memory (RAM) 1230, a short-range communications subsystem 1232, and any other device subsystems generally labeled as reference numeral 1233. To control access, a SIM/RUIM interface 1234 is also provided in communication with the microprocessor 1202. In one implementation, SIM/RUIM interface 1234 is operable with a SIM/RUIM card having a number of key configurations 1244 and other information 1246 such as identification and subscriber-related data as well as one or more PLMN and Service Set ID (SSID) lists and filters alluded to hereinabove.
