Definitions

  • the present invention relates generally to a telecommunications system and method for improved paging, particularly, to a telecommunications system and method for improving paging through use of paging history characteristics associated with each mobile subscriber in the telecommunications system.
  • paging channels used to page or contact mobile stations within the system, e.g., a car cellular phone, which listens for paging signals.
  • a car cellular phone which listens for paging signals.
  • the number of new mobile subscribers and cellular phones in operation has rapidly increased. Since there are usually few paging channels available in a given wireless or cellular telecommunications system, it is clear that conservation of this limited system resource is important to preserve adequate paging capability and prevent excessive communication delays.
  • the present invention is directed to a system and method for controlling the number and scope of pages to a mobile subscriber in a wireless telecommunications system.
  • Paging information about each subscriber is stored within the respective Mobile Switching Center/Visitor Location Register for that subscriber, and pages to the subscriber are modified in accordance with the paging information.
  • FIGURE 1 is a schematic diagram of a conventional cellular network system
  • FIGURE 2 is a schematic diagram further illustrating the cellular network shown in FIGURE 1;
  • FIGURE 3 is a schematic diagram further illustrating the portion of the cellular network shown in FIGURE 2.
  • FIGURE 4 is a block diagram of a Mobile Switching
  • FIGURE 1 of the drawings there is illustrated a Public Land Mobile Network (PLMN) , such as cellular network 10, which in turn is composed of a plurality of areas 12, each with a Mobile Switching Center (MSC) 14 and an integrated Visitor Location Register (VLR) 16 therein.
  • PLMN Public Land Mobile Network
  • MSC Mobile Switching Center
  • VLR Visitor Location Register
  • LA Location Area
  • Each Location Area 18 is divided into a number of cells 22.
  • Mobile Station 20 is the physical equipment, e.g.. a car phone or other portable phone, used by mobile subscribers to communicate with the cellular network 10.
  • a Base Station (BS) 24 is the physical equipment, illustrated for simplicity as a radio tower, that provides radio coverage to the geographical area of the cell 22 in which to handle radio traffic to and from the MS 20.
  • the PLMN Service Area or cellular network 10 includes a Home Location Register (HLR) 26, which is a database maintaining all subscriber information, e.g.. user profiles, current location and routing information, International Mobile Subscriber Identity (IMSI) numbers, and other administrative information.
  • HLR Home Location Register
  • the HLR 26 may be co-located with a given MSC 14 or service one or more separate MSCs 14, the latter of which is illustrated in FIGURE 1.
  • IMSI is a unique 15-digit identification number assigned to each mobile station 20, and includes a Mobile Country Code (MCC) of three digits, a Mobile Network Code (MNC) of two (or three) digits, and a Mobile Subscriber Identification Number (MSIN) , the latter two constituting a National Mobile Subscriber Identity (NMSI) number.
  • MCC Mobile Country Code
  • MNC Mobile Network Code
  • MSIN Mobile Subscriber Identification Number
  • the VLR 16 is a database containing information about all of the mobile stations 20 currently located within the MSC/VLR area 12. If a mobile station 20 roams into a new MSC/VLR area 12, the VLR 16 connected to that MSC 14 will request data about that mobile station 20 from the HLR database 26 (simultaneously informing the HLR 26 about the current location of the mobile station 20) . Accordingly, if the user of the mobile station 20 then wants to make a call, the local VLR 16 will have the requisite identification information without having to reinterrogate the HLR 26.
  • FIGURE 2 there is shown another view of the PLMN Service Area 10, illustrating an MSC 14 and integrated VLR 16 for one of the aforedescribed MSC/VLR areas 12, which contain Location Areas 18a-18f, respectively, therein.
  • a particular MS 20 may roam within a particular LA 18 without forwarding update data.
  • a mobile subscriber, who last used their MS 20 in a particular LA 18, e.g.. LA 18a will be paged there first .
  • the mobile network in looking for said particular MS 20 of said mobile subscriber may page them throughout the entire LA 18a, i.e.. in all of the cells 22 therein, or a subset thereof. In this manner, the mobile subscriber, whose MS 20 is preferably in an active state, may readily communicate and respond to a paging communication.
  • each Location Area 18 within the coverage area of the particular MSC 14/VLR 16 is, as described and illustrated in connection with FIGURE 1, subdivided into a multiplicity of cells 22, shown as cells 22a-f in FIGURE 3.
  • each cell 22, being within a respective LA 18, is served by the same MSC 14/VLR 16 of that respective LA 18.
  • the serving mobile network may identify a particular radio coverage area for a given cell 22 using a Cell Global Identity (CGI) .
  • CGI Cell Global Identity
  • Different cells 22 within a given LA 18 may be distinguished using a Cell Identity and Base Station Identity Code (BSIC) assigned to each serving base station, as is understood to those skilled in this art.
  • BSIC Cell Identity and Base Station Identity Code
  • the initial "local" page is usually within one Location Area, e.g. , within the highlighted LA 18f as illustrated in the figure. It should be understood, however, that the initial page may be more narrow and instead be within one of the particular cells 22a-22f therein. If the mobile subscriber fails to respond to the local page within LA 18f, then a "global" page is performed throughout all of the Location Areas 18 serviced by that MSC 14/VLR 16, i.e.. LAs 18a-f.
  • FIGURE 4 Shown in FIGURE 4 is a representation of the VLR 16 illustrated in the previous figures including therein a multiplicity of subscriber operational data records 16A for a corresponding multiplicity of mobile subscribers in contact with the MSC 14/VLR 16 in question.
  • the respective subscriber data records 16A contain information about the respective mobile subscriber's paging history, i.e.. information about the particular circumstances of that subscriber's paging.
  • the paging history information stored in the respective data records 16A may include some or all of the following illustrative examples:
  • Last known cell identification where mobile subscriber made contact with network (ID) .
  • All or some of the above operational data may be stored within respective fields within the data records 16A.
  • each data record 16A within the VLR 16 has an identifier, e.g.. a pointer, uniquely identifying the particular mobile subscriber.
  • identifier thus preferably contains at least the unique International Mobile Station Identification (IMSI) number for the subscriber, as illustrated.
  • IMSI International Mobile Station Identification
  • TIME and TIME_RESP indicate a standard time reference
  • SUCC is a Boolean flag
  • TOTAL, NUM_UNSUCC and ID are preferably integers. All of the aforedescribed field variables and any additional or alternate field variables may be stored in a conventional manner within the respective fields of the respective data records 16A.
  • a heuristic or rules database 16B used to make decisions based upon the information stored within the aforedescribed data records 16A. It should be understood that either or both of the operational data records 16A and heuristic database 16B may be stored in the MSC 14 or in a combined MSC 14/VLR 16. It should also be understood that the heuristic database 16B stored, for example, in the VLR 16 may be modified by the system operator to better optimize paging performance within the system.
  • SECOND PAGE NO_SECOND_PAGE .
  • a mobile subscriber satisfying the above paging criteria, set forth in the above illustrative rule or heuristic, is most likely out of range since there have been three or more attempts to page them within the last time period without response. Accordingly, local paging is superfluous and not performed. Instead, the system immediately performs a global page. As discussed, this saves paging resources and also reduces the time before indication is sent to the calling subscriber, which in turn saves network resources since the calling party completes their call sooner.
  • SECOND PAGE GLOBAL.
  • the mobile subscriber has just answered a page within the last 5 minutes.
  • the subscriber is likely to still be within the particular cell, e.g.. cell 22e in FIGURE 3, or one of the immediately surrounding cells, e.g.. cells 22a, 22b, 22c, 22d and 22f in LA 18f (and the cells adjoining cell 22e in the neighboring LA 18, not shown) .
  • paging resources may be optimized by first targeting the specific cells in question. If unsuccessful, the subscriber is then preferably paged globally.
  • the twin goals of preservation of system resources and customer satisfaction may be achieved.
  • the data records 16A may include a priority level for the page, e.g.. the priority field illustrated in FIGURE 4.
  • a mobile subscriber or a caller
  • a subscriber may indicate a low priority, e.g.. if the respective MS 20 is only used within a narrow area.
  • the aforementioned parameters i.e.. TIME, TOTAL, SUCC, etc., are preferably initialized at the time of registration or IMSI attachment.
  • the heuristic database 16B is preferably a dynamic database, which, in addition to be modified by the system operator, is able to modify itself as it accumulates a multiplicity of subscribers' data, and respond to patterns within that data to better serve the subscriber base.
  • the variable limits for TIME and TOTAL may be manually or automatically changed in response to subscribers' usage and system needs.
