The present invention relates to a method for controlling an additional service in a mobile communication system, and more particularly, to a method capable of reducing the load of an originating HLR in performing an additional service of an originating subscriber.

It can be said that the difference between a mobile communication network and a fixed communication network is in subscriber mobility. Mobility should be able to grasp subscriber's location movement from network node. The function is being performed by the Home Location Register. In addition, the HLR manages the service registered by the subscriber and delivers the service registered by the subscriber to the exchange to perform the service.

For all services defined in the general specification, the calling subscriber service is controlled by the calling exchanger and the signaling message in the HLR to which the calling party belongs, and the called subscriber service is controlled by the signaling message exchange with the called exchange in the called HLR.

However, as the types of services provided to subscriber terminals are diversified, it is sometimes necessary to perform additional services of the calling subscriber in the called HLR in consideration of the relationship between the calling subscriber and the called subscriber service. In the originating exchange, a large number of signal messages are performed to control the originating subscriber, which causes a lot of load on the originating HLR and the network.

Accordingly, the present invention has been made to solve the problems of the prior art, after storing the calling party service information to the calling exchange when the signal message is delivered, the service information without the call processing process to contact the calling HLR when performing outgoing call processing It is to include in the message sent to the destination HLR to control the subscriber service information in the destination HLR.

Calling subscriber service control method according to the present invention,
(a) at the originating HLR, service characteristic information of the originating subscriber is transmitted to the originating exchange;
(b) if the call processing request is received from the calling subscriber, the calling exchange includes the service characteristic information in a call processing message and transmits it to the called HLR; And
(c) extracting the service characteristic information from the call processing message such that the service of the calling subscriber is controlled in the called HLR.

2 is a signal flowchart illustrating a method for providing additional service according to another embodiment of the present invention.

Referring to FIG. 2, the location information of the mobile terminal is registered with the visitor location register (VLR) of the switching center (MSC) in accordance with the movement of the subscriber carrying the mobile terminal. Hereinafter, the base station (BTS) and the base station controller ( BSC) is collectively referred to as a base station (BS) of a higher concept, and the additional service providing method will be described in detail.

First, when a subscriber carrying a mobile terminal moves to a communication area managed by an arbitrary base station, the base station BS transmits the location information of the mobile terminal detected through wireless communication with the mobile terminal. It is transmitted to the exchange 210 is connected to. Accordingly, the switch 210 transmits a location registration request signal (RegNot: Registration Notification) requesting registration of location information of the mobile terminal 200 to the home location register 220 that manages subscriber information of the mobile terminal. The home location register 220 receiving the location registration request signal RegNot is a database storing subscriber information of the mobile terminal, for example, location information which is an identification number of the exchange 210. Search for and transmitting a registration cancellation (RegCan: Registration Cancellation) signal of the mobile terminal to an exchange and a visitor location register that manage the communication area where the subscriber of the mobile terminal was previously located, RegCan) allows the corresponding exchange and visitor location register to delete all information of the subscriber, and location information indicating the deletion. When receiving a registration cancellation return (regcan) signal, the home location register 220 updates and stores new location information of the mobile terminal in a database, and then registers a location registration request signal for notifying update storage. : Registration Notification Return Result) is transmitted to the corresponding exchange and visitor location register that manages the communication area of the mobile terminal 200, wherein additional service information for the subscriber of the mobile terminal 200 registered location, that is, additional service Subscription and activation information will be sent together.

Accordingly, the switch 210 receiving the location registration response signal regnot stores and manages additional service subscription and activation information for the subscriber of the mobile terminal.

Then, when a dial digit (Dial Digit) is received from the mobile terminal through the base station (BS) is received, it is determined based on the base station data set in the exchange process and processed, the dial digit in advance to provide a specific additional service In the case of a feature code defined as, the device determines the additional service request for each special code and transmits a corresponding message including information identifying the corresponding additional service and its contents to the home location register 220, and accordingly Routing information with the corresponding service node received from the home location register 220, for example, a specific server that provides various additional services, such as a voice message system (VMS) 7z that provides a voice announcement message service or The call connection with the system is performed and processed so that the requested additional service is provided.

As such, in the general mobile telephone system, particularly, the switching center (MSC), the subscriber service and the additional service subscription / activation information stored and managed in the home location register (HLR) are received and requested, so that the additional service requested from the mobile terminal can be provided. In order to perform the call connection with the service node that provides the supplementary service, or to provide a series of supplementary services for updating the supplementary service activation information set in the home location register.

3 is a signal flow diagram illustrating a method for controlling an additional service of an originating subscriber in a destination home location register according to another embodiment of the present invention.

Referring to FIG. 3, a location registration request signal is first transmitted from a mobile terminal to an originating exchange 300, and the originating exchange 300 transmits a location registration request message (RegistrationNotification) to the originating HLR 310. The originating HLR 310 transmits an Origination-Service Feature indicator (O-SFI) to a detailed information request message (QualificationDirective Invoke), a location notification response message (RegistrationNotification ReturnResult), or a detailed information response message (QualificationRequest ReturnResult). Included in the transmission to the outgoing exchange 300. In addition, when O_SFI value is included in FeatureRequest and OriginationRequest ReturResult and transmitted, it is included in a location request request message (LocationRequest Invoke) and transmitted. That is, it transmits in preference to O_SFI stored in the exchange.

When the originating MSC 300 receives the service characteristic information SFI included in the operation QUD, RegNot, the corresponding MSC 300 stores the corresponding information without conversion and outputs the subscriber information when the subscriber information is output. This is similar to the form in which an Origination Trigger, or an Initiation Trigger TerminationTrigger signal is output.

Optionally, when the originating subscriber service characteristic information (OSFI) is stored in the visitor location register (VLR) at the time of SMS transmission, the OSFI parameter is added and transmitted in the SMDPP.

The originating subscriber service characteristic information (OSFI) must be delivered to the destination HLR similarly to the CallingPartyNumberDigits. That is, in the case of A => B => C => D, the calling number transmitted to the D HLR is A, and OSFI must also be A subscriber information.

Subsequently, a dial digit is input from the mobile terminal to transmit the called subscriber location inquiry request message (LFI) including the service characteristic information (SFI) when the calling exchange location request message is transmitted from the originating exchange 300 to the called HLR 320. The service characteristic information (SFI) included here transfers the value received by QUD, QUL or RegNot to the destination HLR 320 without change.

The called HLR 320 controls the additional service of the calling subscriber according to the received service characteristic information (OSFI) of the calling subscriber.

4 illustrates service characteristic information parameters for providing additional service according to another embodiment of the present invention.

Referring to FIG. 4, the Origination Service Feature Indicator includes length information indicating a data length of transmission information; Tag information indicating that transmission information transmitted afterwards is activation information for an additional service; And activation information (feature activity) indicating whether to activate each additional service.

As shown in FIG. 4, the activation information enables identification of activation of each additional service allocated to 2 bits in four states.

That is, each supplementary service is not provided ('00'), "not set ('01')", "set but not activated ('10')", "set and activated ( "11 ')" is activation information for identification. For example, when the 2-bit activation information corresponding to the caller's telephone number verification service (Caller_ID), which is an additional service for requesting and displaying the caller's telephone number, is set to '11', the caller's telephone number verification service is set and set. You can identify that it is active.
