Definitions

  • the present invention relates to mobile systems and particularly to the management of subscriber data therein.
  • a solution for maintaining subscriber data in a home location register (HLR) and in a visitor location register (VLR) is previously known in for example the GSM system (Global System for Mobile Communication).
  • the home location register maintains subscriber data regarding all mobile subscribers in a network.
  • the structure of a home location register is a computer and a data storage associated therewith.
  • As a mobile subscriber moves in the mobile network necessary subscriber data are copied from the home location register to the visitor location register within whose area the mobile subscriber is located at each particular time.
  • information on the visitor location register in whose area the mobile subscriber is located is stored in the home location register.
  • a visitor location register may be located in association with a mobile services switching centre, in which case the area of the visitor register may be the area covered by said mobile services switching centre.
  • the object of the invention is to solve the above problems by providing a solution allowing simpler management of large amounts of subscriber data in a mobile system.
  • a mobile system comprising a mobile network having a mobile services switching centre for switching connections in the mobile network, and at least one subscriber database server for maintaining data on the subscribers of the mobile network.
  • the mobile services switching centre comprises means for querying for and receiving subscriber data from the subscriber database server wherein subscriber data are maintained in www (World Wide Web) page format
  • the subscriber database server comprises at least one www page for each subscriber in the mobile network, in which page the subscriber's subscriber data are stored, the search address of the www page being created based on the subscriber's identity.
  • the invention also relates to a mobile services switching centre for switching connections in a mobile network.
  • the mobile services switching centre is characterized in that the mobile services switching centre comprises means for querying for and receiving subscriber data from a subscriber database server wherein subscriber data are maintained in www page format.
  • the invention further relates to a subscriber data main server for maintaining subscriber data in a mobile network.
  • the main server is characterized in that the main server comprises, for each subscriber in the mobile network, at least one www page wherein the subscriber's subscriber data are stored, the search address of the www page being created based on the subscriber's identity.
  • the invention still further relates to a subscriber data local server for temporary storage of subscriber data.
  • the local server is characterized in that it comprises means for receiving queries for the subscriber data from a mobile services switching centre, means for retrieving the queried subscriber data from a database in the local server, means for retrieving the queried subscriber data further from a main server if said data are not found in the database of the local server, means for transferring the retrieved subscriber data to the mobile services switching centre, and means for storing the retrieved subscriber data in the local server in www page format.
  • the idea of the invention is to apply www, http (Hypertext Transfer Protocol), html (Hypertext Markup Language), IP (Internet Protocol) and other Internet technology in the subscriber databases instead of the present HLR/VLR technology.
  • the mobile services switching centre has to be provided with an IP interface, via which call control and other programs requiring data are able to query for the information they require, i.e. www pages.
  • the mobile services switching centre uses a www address as the search address, the address indicating the desired subscriber data page and being created based on the subscriber's identity and a control function.
  • the mobile services switching centre provides a path for data to be transferred, but the data associated with special services are processed and managed in the IP network.
  • IP network having higher-capacity hardware facilitates data retrieval and management. As services become more versatile, necessary new functions are increasingly easier to incorporate into IP network servers with different programming tools.
  • the system comprises a subscriber data main server wherein subscriber-specific www pages are stored, and at least one subscriber data local server between a mobile services switching centre and the main server for temporarily maintaining subscriber data.
  • the local server is used for buffering subscriber data. Since not all queries have to be transferred all the way to the main server, but the data are found in the local server, access to data does not become unnecessarily slow even in a large network.
  • the main server comprises at least a subscriber-specific main page wherein the most generally needed subscriber data are stored and whereto said search address points, and at least one subpage wherein the subscriber data needed in special cases are stored and whose search address is created by completing the search address of said main page.
  • This division also aims at faster data retrieval.
  • the main server comprises means for maintaining a www page specific log regarding subscriber data queries such that the log contains information on the local server that sent a query for a page and the time the query was sent. For example, when an operator or dispatcher changes the subscriber data, the changed data have to be transferred to the local servers that, based on a time stamp, have corresponding usable data. In this case, a check can be made in the log to find out the location of such no-good data and transfer an update there.
  • the local server comprises means for providing the new or changed subscriber data to be stored in the local server with a time stamp, means for checking the time stamp when the next query or notice of change regarding the same subscriber data is received, means for selecting the stored data if a predetermined term from the storage has not lapsed. This avoids unnecessary data searches.
  • the data may be stored in the local server, provided with a time stamp. If the same data are queried for again soon, the data do not have to be searched for again in the main server, but sufficiently recent stored data can be used directly. This requires that a term be set indicating how long the old data are usable.
  • FIG. 1 is a block diagram of the system of the invention in a situation when a query is made for the subscriber data of subscriber A,
  • FIG. 2 is a block diagram of the system of the invention in a situation when a call is established between subscribers A and B,
  • FIG. 3 is a block diagram of the system of the invention in a situation when a group call is established
  • FIG. 4 is a block diagram of the system of the invention in a situation when subscriber location data are updated
  • FIG. 5 is a block diagram of the system of the invention in a situation when a dispatcher updates group data
  • FIG. 6 is a block diagram of the system of the invention in a situation when an operator updates subscriber data.
  • the figures schematically show different data search and management cases. For example, they may describe the invention applied to the TETRA system (Terrestrial Trunked Radio) or some other mobile system.
  • TETRA Terrestrial Trunked Radio
  • FIG. 1 is a block diagram of the system of the invention in a situation when a query is made for the subscriber data of subscriber A.
  • the system shown comprises a mobile station MSA of subscriber A, base stations (BS) BSA, mobile services switching centres (MSC) MSCA, and a local server LSE and a main server CSE.
  • BS base stations
  • MSC mobile services switching centres
  • LSE local server
  • main server CSE main server
  • the main server CSE comprises a subscriber database. All changes in the data are primarily made therein. Depending on the size of the network, the number of subscribers and service types, there may be several main servers CSE, which divide the load so as to optimize the management of the number of subscribers, service types or other data. As FIG. 1 shows, besides a main server CSE, a large network comprises local servers LSE.
  • the www pages generated from mobile subscriber data are retrieved from the subscriber database server according to the http standard. For example, the search address http://www.mobile-data.xxxnetwork/subsdata/ ⁇ subsid>, where ⁇ subsid>is the identifier of the desired subscriber, gains access to a page containing subscriber-specific data.
  • This page may contain links to other pages that contain data needed in special cases and are accessed by merely completing the address.
  • the address of a subpage containing subscriber data relating to special services is e.g. http://www.mobiledata.xxxnetwork/subsdata/ ⁇ subsid>/ ⁇ addinfo>, where ⁇ subsid>is the identifier of the desired subscriber and ⁇ addinfo>the address of the desired special information. Since for example in the TETRA system, a subscriber may have several different identifier numbers and a text form identifier, the same subscriber data may have several different ⁇ subsid>addresses referring to it.
  • step 1 in FIG. 1 subscriber A makes a call or registers via the base station BSA.
  • step 2 the MSCA queries for a www page including the subscriber's service data of the subscriber database server. This could be e.g. a ‘services of subscriber A’ www page. Since in this exemplary case, said information is not found in the local server LSE, the query is sent forward to the main server CSE in step 3.
  • step 4 the main server CSE returns the queried subscriber data to the local server LSE, which in step 5 sends the service data further to the querying MSCA.
  • the local server LSE stores the data in its files.
  • the MSCA receives the data stored in association with the previous call directly from the local server LSE. This means that the data does not have to be queried for again from the main server CSE.
  • FIG. 2 is a block diagram of the system of the invention in a situation when a call is established between subscribers A and B.
  • the system shown comprises a mobile station MSA of subscriber A, a mobile station MSB of subscriber B, base stations BSA, BSB, mobile services switching centres MSCA, MSCB, local servers LSEA, LSEB, and a main server CSE.
  • subscriber A makes a call via the BSA.
  • the MSCA of subscriber A inquires about the location of the MSB of subscriber B from its local server LSEA. For example, a ‘subscriber location’ www-page could be involved.
  • step 3 an inquiry is made to the main server CSE.
  • step 4 the main server CSE returns the inquired data to the LSEA, which in step 5 sends the received data further to the MSCA.
  • the LSEA stores the data for future inquiries.
  • step 6 the call is routed via the network of MSCA and MSC to the MSCB of subscriber B.
  • step 7 the MSB of subscriber B queries its LSEB for the service data of subscriber B, e.g. from a ‘called subscriber services’ www page. If need be, the inquiry passes all the way to the CSE. If the data indicate that a call is allowed to subscriber B, the MSCB switches it to subscriber B in step 8.
  • FIG. 3 is a block diagram of the system of the invention in a situation when a group call is established.
  • the system shown comprises a mobile station MSA of subscriber A, other mobile stations MS, base stations BSA, BS, mobile services switching centres MSCA, MSC, local servers LSEA, LSE, a main server CSE, and a dispatcher workstation DWS.
  • subscriber A initiates a group call.
  • the MSCA inquires group data of its local server LSEA, e.g. from a ‘group services’ www page. Since in this exemplary case the group data are not found in the LSEA, in step 3, the LSEA makes an inquiry for the data further to the main server CSE.
  • step 4 the CSE returns the group data to the LSEA in the form of a www page, and, in step 5, the LSEA transfers the data to the MSCA.
  • step 6 the MSCA makes group call switchings to other mobile services switching centres MSC in the group's area and to the DWS.
  • step 7 the other mobile services switching centres MSC inquire group data of their local servers LSE. If need be, the inquiry for these data is made all the way to the CSE.
  • the mobile services switching centres make group call switchings to a radio network.
  • FIG. 4 is a block diagram of the system of the invention in a situation when subscriber location data are updated.
  • the system shown comprises a mobile station MSA of subscriber A, a base station BSA, a mobile services switching centre MSC, local servers LSEA, LSE, a main server CSE and a dispatcher workstation DWS.
  • subscriber A changes his location.
  • the MSCA requests that the LSEA change the location data.
  • the LSEA relays the task to the CSE using e.g. a POST or PUT operation, which updates the data in e.g. a ‘subscriber location’ www page.
  • the CSE returns new location data to the LSEA in the form of a www page.
  • step 5 the LSEA acknowledges the change in the location data to the MSCA.
  • step 6 if need be, the CSE notifies also other local servers LSE of the change in the location of subscriber A in the form of a www page.
  • step 7 the CSE notifies the change in the location to other special servers, such as the DWS, in the form of a www page. Steps 6, 7 and 4 may occur simultaneously.
  • step 1 subscriber A performs e.g. a group attach/detach measure, i.e. attaches to or detaches from a group.
  • step 2 the MSCA notifies the change to the LSE, which may be a separate local server for group data.
  • step 3 the LSE notifies the change in the group data further to the CSE.
  • steps 4 to 7 are the same as in a location data update, i.e. comprise returning the new group data to the LSEA, transferring an acknowledgement to the MSCA and transferring the changed data to other local servers LSE and to special servers, such as the dispatcher workstation DWS.
  • FIG. 5 is a block diagram of the system of the invention in a situation when a dispatcher updates group data.
  • the system shown comprises a dispatcher workstation DWS, a local server LSE, a main server CSE and one special server CIS (Communications Interface Server).
  • the dispatcher uses the DWS, the dispatcher changes the group data in the CSE using e.g. a POST or PUT operation e.g. to the www page of said services of the group. Since the LSE may have data that are usable according to the time stamp but in reality out of date, the changed data are to be relayed to the LSE.
  • the CSE notifies the change to one or more group data local servers LSE.
  • the CSE keeps a page-specific log of the inquiring local servers LSE.
