Description

CALLER ID SERVICE SYSTEM AND THE METHOD
Technical Field The present invention relates generally to caller identification (ID) services and more particularly to a caller ID services system and method thereof for providing call-recipient terminal with various caller ID information designated by subscribers in a telecommunications network. Background Art Recently, with the development of mobile communications technology, various kinds of communication terminals have been widely used, which simultaneously provide communication function and picture display function, such as mobile phones, PDAs, IMT-2000 terminals or notebooks . Such communication terminals provide various functions and supplementary services such as on/off line game, E- mail, Short Message Service (SMS) , Personal Information Management System (PIMS) or electronic settlement, as well as a basic telephone function. One of universally and widely used services among them is caller ID service, by which, when calling is received to particular subscriber terminal, incoming-side Mobile Switching Center (MSC) caller ID information, i.e., call-originator number, etc. to a display of recipient's terminal. Some of the subscriber terminals offer a function that provides displays of the recipient's terminals with call-originator names or images together with the call-originator number. Also, recently, in conformity with the qualitative and quantitative development of services concerning subscriber terminals, it is practically needed caller ID service that provides further avatar and other information of the call- originator, without satisfying conventional service that simply provides only name and number of the call- originator. With regards to this fact, there has been proposed a technology concerning mobile phone, which is disclosed in Korean Utility Model Application No. 2002-0031183 (title: Mobile phone having function that provides a display thereof with image upon receiving connecting call) , wherein according to caller ID signal simultaneously transmitted when incoming calling bell is ringing at the recipient's mobile phone (cellular phone and PCS phone) , image (such as picture, avatar or moving picture, etc.) concerning call- originator, which has been previously stored in the recipient's mobile phone, is displayed together with call- originator number on a screen of the recipient's mobile phone while bell sound is ringing. However, in the above prior technology, a communication terminal (or mobile phone) a subscriber uses, serves as the central operating body for caller ID and to this end, mass information desired to display together with the call-originator number, for example, picture, avatar or moving picture, etc. has to be stored in a memory of the terminal, so that the subscriber terminal has to support mass storage memory functions. Accordingly, it was caused a problem in that conventional communication terminal, which provides low memory capacity function, cannot sufficiently offer desired caller ID service. Disclosure of the Invention Therefore, the present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide various caller ID information comprising either name (or pet name, etc.), business card, image, bell sound, emoticon, avatar or text, or combinations thereof, which are registered by subscribers in conjunction with caller ID service, typically offered to a communication terminal . Another object of the present invention is to provide recipient's terminal with particular display information designated by subscribers and also to provide even a conventional communication terminal with various caller ID information offering service, by way of registering caller ID information by subscribers, required to caller ID service, to a separate caller information service server. In order to accomplish these objects, there is provided a caller ID service system for providing recipient's terminal with caller ID service in communication network, the system comprising: a Home
Location Register (HLR) for setting information of whether or not subscribed to caller ID service and information on active/inactive state of the system to profile information and for managing the information, and for implementing routing request function for providing recipient's terminal with particular caller ID information service request and the caller ID information; outgoing/incoming Mobile Switching Center (MSC) for temporarily storing particular caller ID information and providing corresponding recipient's terminal with the stored particular caller ID information, in accordance with routing request from the HLR; and a service information server for storing and managing various caller ID information designated by subscribers of caller ID information service, and for providing particular caller ID information response function corresponding to the request from the HLR. Here, it is characterized in that the caller ID service server comprises a subscriber database (DB) interworking process unit for storing caller information identifier to be provided to the recipient's terminal in subscriber DB, together with subscriber information and managing them; caller ID information database (DB) interworking process unit for storing caller ID information designated by subscribers in caller ID information DB, together with caller information identifier and managing them; service process unit for extracting particular caller ID information managed by caller ID information DB interworking process unit based on subscriber information managed by the subscriber DB interworking process unit and transmitting the extracted information; and a network interworking unit for transmitting particular caller ID information extracted by the service process unit to the HLR, by way of interworking with HLR through communication network. It is also characterized in that the subscriber DB stores caller information identifier specified from any one of call-originator number and corresponding caller ID information, recipient group, recipient age group, gender or calling time, or combination thereof. Further, it is characterized in that the caller ID information includes any one of call-originator name with caller information identifier, business card, image, bell sound, emoticon, avatar or text, or combination thereof.

Best Mode for Carrying Out the Invention Reference will now be made in detail to the preferred embodiments of the present invention. Fig. 1 is a schematic view of mobile communication network to which caller ID service of the present invention is offered. Caller ID service of the present invention provides recipient's terminal with various caller ID information designated by call-originator. The caller ID information includes any one of call-originator name (or pet name) corresponding to call-originator number to be displayed on a recipient's terminal, business card, image, bell sound, emoticon, avatar or text, or combination thereof. The caller ID information is provided to the recipient's terminal by way of interworking with existing MSC and other communication network equipment, using a caller information service server for storing and managing the caller ID information. As shown in Fig. 1, caller ID service system of the present invention is operated based on a construction of a mobile communication network, comprising: Mobile switching
Centers (MSCs) 10a and 10b having Visitor Location Register (VLR) ; Home Location Register (HLR) 15 storing subscriber information with a separate computer; Basestation
Transceiver Subsystem (BTS) for processing wireless connection; BaseStation controller (BSC) positioned between MSCs 10a and 10b and BTS so as to control and manage plural BTSs; and Mobile Station (MS or mobile service subscriber) . Caller information service server 20 of the present invention interworks with MSCs 10a and 10b and HLR 15 through communication network so as to embody the present invention. In Fig. 1, for convenience of description, each constitutional element of the mobile communication network is shown to be separated into incoming-side and outgoing- side in conjunction with processing of outgoing/incoming calls. Here, with a more detailed description of communication network equipment for implementing the caller ID service according to present invention, the HLR 15 does not only function as one of components of an existing communication network, but also provide a function for setting information on whether or not subscribed to the caller ID service and information on active or inactive state of the caller ID service to profile information so as to manage them, and requesting particular caller ID information to the caller information service server 20 and routing to incoming-side MSC 10b for providing recipient's terminal with particular caller ID information. The incoming/outgoing-side MSCs 10a and 10b do not only function as one of components of an existing communication network, but also perform a function of temporarily storing particular caller ID information according to a request for particular caller ID information to caller information service server 20 interworking with HLR 15 and a request for routing from HLR 15, and providing recipient's terminal with particular caller ID information. Further, caller information service server 20 stores and manages various caller ID information designated by subscribers so as to provide caller ID service, such as, for example, any one of call-originator name (or pet name) corresponding to call-originator number, business card, image, bell sound, emoticon, avatar or text, or combination thereof, and performs a function for answering particular caller ID information corresponding to request of HLR 15. As shown in Fig. 2, the caller information service server 20 includes a subscriber DB interworking process unit 21 for storing caller information identifier in the subscriber DB, together with subscriber information, and managing them, the caller information identifier being specified according to subscriber information required to specify the caller ID information to be provided on recipient's terminal, including any one of call-originator number and corresponding caller ID information (name or phone number, etc.), recipient group (friends, clubs, family, relatives, company or customer, etc.), recipient age group, gender or calling time, or combination thereof; a caller ID information DB interworking process unit 22 for storing caller ID information designated by subscribers in caller ID information DB, together with caller information identifier and managing them, the caller ID information including call -originator name (or pet name, etc.), business card, image, bell sound, emoticon, avatar or text, or combination thereof; a service process unit 23 for extracting particular caller ID information managed by caller ID information DB interworking process unit 22 based on subscriber information managed by the subscriber DB interworking process unit 21, and transmitting the extracted information HLR 15 through communication network, so as to process an operation of a server concerning a series of caller ID services; and a network interworking unit 24 for transmitting particular caller ID information transmitted from the service process unit 23 to corresponding HLR 15, interworking with HLR 15 through communication network based on No. 7 protocol; and an external inteworking process unit 25 for providing a function for interworking with an external device for storing caller ID information in the subscriber DB interworking process unit 21 and caller ID information DB interworking process unit 22 and managing stored information. Here, the external interworking process unit 25 comprises a web interworking unit 25-1 for providing a function of production and management of caller ID information through a contents provider based on internet; a terminal interworking unit 25-2 for providing a function of management of caller ID information service and a function of storage and management of particular caller ID information through a terminal based on internet; and an ARS (Automatic Response Service) interworking unit 25-3 for providing a function of management of caller ID information service and a function of storage and management of particular caller ID information through auto answering device . Hereinafter, a detailed description will be made regarding operation for performing caller ID service system constructed as mentioned above in accordance with the present invention in reference to FIGs . 3 and 4. First, to receive the foregoing caller ID service, a user must be subscribed to a caller ID service offered by a mobile communication carrier. Additionally, the service must be activated. The HLR 15 makes management of information on whether or not subscribed to this caller ID service and whether or not the service is activated. Further, in order to provide the recipient's terminal with various caller ID information as in the present invention, at least one of call-originator number and particular caller ID information corresponding to the call- originator number, including, for example, any one of call- originator name (or pet name, etc.), business card, image, bell sound, emoticon, avatar or text, or combination thereof, must be not only registered to the service information server 20, but also allowed to be managed. To this end, the caller information identifier is stored in the subscriber DB of the subscriber DB interworking process unit 21 and allowed to be managed, and at the same time, various caller ID information designated by subscribers is stored in the service information DB of the service information interworking process unit 22, together with caller information identifier, and allowed to be managed, the caller information identifier being specified according to caller ID information to be provided on recipient's terminal through the web interworking unit 25-1 or the terminal interworking unit 25-2 and the ARS interworking unit 25-3, including any one of call-originator number and corresponding caller ID information (name or phone number, etc.), recipient group (friends, clubs, family, relatives, company or customer, etc.), recipient age group, gender or calling time, or combination thereof. In this manner, when various caller ID information desired to display on the recipient's terminal 20 by subscribers of caller ID service are registered to the service information server 20 (Step S41) , the caller ID service is provided to the subscriber according to operational procedures described below. That is, as an arbitrary call-originator dials the phone number of desired call-recipient to attempt a call using his communication terminal, it is checked whether or not an outgoing call is generated from the call-originator (Step S42) . If the outgoing call is generated, the outgoing-side MSC 10a requests for location information of the call-recipient to the HLR 15 by transmitting a location request message to the HLR 15. At this time, the HLR 15 receiving the location request message searches subscriber information of the corresponding call-recipient to check whether or not the call-recipient is subscribed to the caller ID service and whether or not the caller ID service is activated (Step S43) . If the call-recipient is not subscribed to the caller ID service or if the service is not activated, a call is established with the incoming-side MSC 10b according to a typical call process procedure (Step S44) . However, if the call-recipient has been subscribed to the caller ID service and if the service has been activated, a caller information request message is transmitted to the service information server 20 in order to provide the caller ID service according to the present invention. Here, as a response to the caller information request, the service information server 20 adds particular caller ID information desired to display on the recipient's terminal to the caller information response message and transmits them to the HLR 15. Thus, when the HLR 15 receiving the request for location information of the corresponding call-recipient to outgoing call from arbitrary call-originator whose subscribed caller ID service is activated, requests for caller ID information to service information server 20 using corresponding call-originator number (step S45) , the service process unit 23 of the service information server 20 selects previously registered caller information identifier from the subscriber DB interworking process unit 21 in conformity with the call-originator number. At this time, the selected caller information identifier is specified according to any one of caller ID information (name or phone number, etc.) corresponding to the call- originator number, recipient group, recipient age group, gender or calling time, or combination thereof. And, the service process unit 23 of the service information server 20 extracts particular caller ID information, including any one of call-originator name (or pet name, etc.) designated by subscribers, business card, image, bell sound, emoticon, avatar or text, or combination thereof and desired to display on the recipient's terminal, from the service information DB interworking process unit 22, using the selected caller information identifier, and then transmits corresponding caller ID information to the HLR 15 through the network interworking unit 24. Then, the HLR 15 adds particular caller ID information, transmitted from the service information server 20 so as to provide recipient's terminal with caller ID service, to the routing request message, and transmits them to the incoming-side MSC 10b (sep S46) . At this time, the incoming-side MSC 10b temporarily, stores corresponding caller ID information to inside memory and adds Temporary Local Directory Number (TLDN) for a call set-up in response to corresponding routing request, i.e., routing information for recipient, to routing response message, and transmits them to the HLR 15 (step S47) . Thus, the HLR 15 receiving the routing response message transmits the incoming information transmitted from the corresponding incoming-side MSC 10b in response to the request for location information of the outgoing-side MSC 10a. In this case, the incoming information is included in the location response message and is transmitted to the outgoing-side MSC 10a. Then, the outgoing-side MSC 10a transmits a call request message including incoming information for a call set-up with incoming-side MSC 10b, to the incoming-side MSC 10b. As a response to this, the incoming-side MSC 10b receiving the corresponding call request message transmits a call connect message to the outgoing-side MSC 10a, so that there is generated one call between the outgoing-side MSC 10a and the incoming-side MSC 10a (step S48) . Further, the incoming-side MSC 10b determines whether or not particular caller ID information temporarily stored to inside memory is displayed on recipient's terminal by checking a function of the corresponding recipient's terminal using incoming information included in the call request message (step S49) . At this time, if particular caller ID information designated by call-originator cannot be displayed on the recipient's terminal, a series of operations for call set-up for calling the recipient's terminal through the BSC and the BTS using the incoming information included in the call request message in accordance with typical call process procedure (Step S50) . After this, when the recipient makes response to the call, the call response message corresponding to incoming call response of the recipient's terminal is transmitted to the outgoing-side MSC 10a, so that speech path between the originator's terminal and the recipient's terminal is formed so as to connect call therebetween (steps S51 and S56) . However, in the step S49, if particular caller ID information designated by call-originator can be displayed on the recipient's terminal, the incoming-side MSC 10b performs a series of operations for call set-up for calling the recipient's terminal through the BSC and the BTS using the incoming information included in the call request message. At this time, the incoming-side MSC extracts particular caller ID information temporarily stored to its inside memory and transmits the extracted information to the recipient's terminal, so that caller ID information is continuously displayed on a screen of the recipient's terminal until the recipient makes response to the call (steps S52 to S54) . After this, when the recipient makes response to the call, the recipient's terminal stops displaying of the corresponding caller ID information (step S55) . In this case, incoming call response of the recipient's terminal is reported to the incoming-side MSC 10b through the BTS and the BSC. Accordingly/ the incoming-side MSC 10b transmits call response message corresponding to incoming call of the recipient's terminal to the outgoing-side MSC 10a, so that speech path between the originator's terminal and the recipient's terminal is formed so as to connect call therebetween (step S56) . Meanwhile, according to another embodiment of the present invention, there can be provided a method for caller ID service, the method comprising the steps of: determining whether or not particular caller ID information can be displayed on the recipient's terminal by checking a function of the recipient's terminal through searching subscriber information for the corresponding recipient, before the HLR receives particular caller ID information desired to display on the recipient's terminal from the service information server and transmits the received information to the incoming-side MSC; and transmitting the corresponding caller ID information to the incoming-side MSC only when particular caller ID information designated by originator can be displayed on the recipient's terminal. If particular caller ID information cannot be displayed on the recipient's terminal, the corresponding caller ID information is not transmitted to the incoming-side MSC, preventing unnecessary consumption of call resources. In this case, an operation of checking a function of the recipient's terminal is unnecessary at the incoming-side MSC. Industrial Applicability AS can seen from the foregoing, according to the present invention, various caller ID information can be provided which includes any one of name (or pet name, etc.) registered by subscribers in conjunction with caller ID service provided to the communication terminal, business card, image, bell sound, emoticon, avatar or text, or combination thereof. Further, according to the present invention, caller ID information by subscribers required for caller ID service is registered to a separate service information server, so that particular caller ID information designated by the originator can be displayed on the recipient's terminal, possibly providing various caller ID services by means of conventional communication terminal. Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
