Definitions

  • the present invention relates generally to a method of providing and synchronizing separate data sets. More specifically, the present invention relates to a method in a wireless communication device synchronizing one data set with another based upon a data parameter.
  • CDMA Code Division Multiple Access
  • PRL Preferred Roaming List
  • SID System Identification
  • NID Network Identification
  • the mobile determines the most appropriate network to register itself.
  • the mobile may receive a new PRL appropriate for the current environment of the mobile over the air to replace the existing PRL.
  • the mobile supports three types of roaming indicators associated with the PRL, which help notify the user the roaming status of the mobile in the current environment.
  • the first type of the indicators may indicate that the mobile is in a home network, i.e., not roaming, by having the roaming indicator light turned off; the second type of the indicators may indicate that the mobile is in a preferred roaming network by having the roaming indicator light turned on; and the third type of the indicators may indicate that the mobile is in a non- preferred roaming network by having the roaming indicator light flashing.
  • enhanced roaming indicators As defined in TIA/EIA TSB58b section 8.1, enhanced roaming indicators (“ERI"), supporting more than three types of indicators, may be provided in the mobile to enhance the roaming condition conveyed to the user. However, as the mobile roams and its PRL is replaced with a new and different PRL, the ERI may not be correctly associated with the new PRL.
  • FIG. 1 is an exemplary environment where the method of the present invention may be initiated
  • FIG. 2 is an exemplary flow chart of the first embodiment of the present invention in a wireless communication device
  • FIG. 3 is an exemplary flow chart of the second embodiment of the present invention in a wireless communication device.
  • FIG. 4 is an exemplary flow chart of the third embodiment of the present invention in a network.
  • the present invention generally relates to a method in a wireless communication device for synchronizing two sets of data that are received at two separate instances.
  • a first set of data for example, a preferred roaming list
  • PRL PRL
  • EPRL extended preferred roaming list
  • ERI enhanced roaming indicators
  • the wireless communication device may receive a new PRL, which may not be synchronized to the current ERI already stored in the device, depending upon the availability of systems and networks in the new environment.
  • the wireless communication device receives an ERI that is synchronized to the new PRL based on a parameter of the new PRL.
  • FIG. 1 is an exemplary environment where some aspects of the present inventions may be practiced.
  • a wireless communication device 102 located in a first region 104 which has been operating in a first network 106 provided by Carrier A, leaves the first region and enters a second region 108, it may be necessary for the wireless command device to register and operate in a second network 110 provided by a different carrier, Carrier B.
  • a home carrier of the wireless communication device may have different contracts with each of the Carriers A and B, which may affect the fee charged to the wireless communication device, for example when the wireless communication device is roaming.
  • the wireless communication device may receive a preferred roaming list. In other applications, the mobile device may receive lists or data sets other than a preferred roaming list.
  • this process is initiated when the wireless portable communication device, preferably a portable radiophone, leaves a first region and enters a second region.
  • the wireless communication device receives a preferred roaming list information such as, but not limited to, a preferred roaming list ("PRL") or an extended preferred roaming list (“EPRL”), at block 204.
  • PRL preferred roaming list
  • EPRL extended preferred roaming list
  • the wireless communication device determines if the received preferred roaming list information contains information referring to a functionality extension table such as but not limited to, a roaming indicator and an enhanced roaming indicator, which may compliment the functionality of the received preferred roaming list information.
  • any functionality extension table previously stored may be deleted in block 208, and the wireless communication resumes its normal operation in block 210.
  • the wireless communication device requests for the functionality extension table information in block 212, and in response to the request, the wireless communication device receives the functionality extension table information that is synchronized to the received preferred roaming list information in block 214. The wireless communication device then updates the stored functionality extension table information in block 216, ends the process in block 210, and resumes its normal operation.
  • a third database such as, but not limited to, a call prompt table further complimenting at least one of the preferred roaming list and the functionality extension table, may be received based upon a reference included in the preferred roaming list information or the functionality extension table information.
  • the call prompt table may be included in the preferred roaming list or the functionality extension table.
  • FIG. 3 there is provided an exemplary flow chart of another aspect of the invention in a wireless communication device.
  • this process is initiated when the wireless portable communication device leaves the first region and enters the second region in block 302.
  • the wireless communication device Upon entering the second region, the wireless communication device receives functionality extension table information in block 304. Based upon the received functionality extension table information, the wireless communication device requests to receive a corresponding preferred roaming list information in block 306. The wireless communication device then receives the corresponding preferred roaming list information that is synchronized to the received functionality extension table information in block 308, ends the process in block 310, and resumes its normal operation.
  • the synchronization between the preferred roaming list information and the functionality extension table information may be accomplished by maintaining a list of compatible versions or a list of compatible pairs in the network from which the wireless communication device receives the information.
  • the network maintains a plurality of preferred roaming lists and roaming indicator table, which may be updated periodically.
  • the network also maintains a listing of a plurality of compatible preferred roaming list and roaming indicator table pairs in block 404.
  • the preferred roaming list version 1 may be compatible with the roaming indicator table version 3 but not with the roaming indicator table version 2; and the preferred roaming list version 2 may be only compatible with the roaming indicator table version 5.
  • the network detects a wireless communication device leaving the first region and entering the second region, the network transmit one of the preferred roaming list having a version number of the plurality of preferred roaming lists maintained in the network in block 406.
  • the network receives the version number and a request for a corresponding roaming indicator table in block 408.
  • the network may receive the capability and status of the wireless communication device to avoid transmitting a roaming indicator table that is compatible with the preferred roaming list but not with the wireless communication device.
  • the network selects the appropriate roaming indicator table that is synchronized with the preferred roaming list having that version number in block 410.
  • the network then transmits the selected roaming indicator table in block 412, and completes the process in block 414.
