The present invention relates to a service in an IMS based network, and more particularly, to a service system, a service method thereof, and a terminal registration method in an IMS based network.

As the user's communication environment has evolved into the 3rd generation (3G) network and the IMS (IP Multimedia Subsystem) structure is introduced to provide various convergence types of services, there is a limitation in providing a service using a number embedded in an existing terminal. There is. In particular, when a user uses various types of terminals, there is a need for a method of identifying a user in order to provide a user-based service while using a different number according to the type of a call service.

In addition, when a user uses various types of terminals such as cell phones, VoIP phones, and the like, call services are provided based on numbers, while content services need to be provided based on users. For example, it is necessary to make specific ringtone contents available only once to make them available to different terminals of the same user, or even to purchase coloring contents only once, the same contents need to be provided to the other party calling his / her own terminal as ring back tone. .

In this case, when a user tries to use a service through different types of terminals, a system for applying identifiers of the user and the terminal is required to provide a consistent service.

As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

In addition, when a part is said to "include" a certain component, this means that it may further include other components, except to exclude other components unless otherwise stated.

1 is a configuration diagram of a service system in an IMS based network according to an embodiment of the present invention.

1, a service system in an IMS-based network according to an embodiment of the present invention, the content DB 110, content purchase server 120, application server 130, subscriber information DB 140, call processing The server 150 includes a registration server 160.

User 1 has different types of terminals as needed. For example, you can use cellular phones and Internet phones, each with a different number. The subscriber information DB 140 stores the user identifier of the subscriber, the type of the terminal owned by the subscriber, and a telephone number corresponding thereto. The content DB 110 stores the content purchase information of the subscriber. The information registration server 160 maintains subscriber information, receives a registration request from the terminal when power is applied to each terminal, processes it, and verifies a valid number to the terminal and informs the terminal. The call processing server 150 delivers a message for a basic call, and passes a message to a corresponding application server 130 when a specific additional service is to be provided. The content purchase server 120 shows the content desired by the subscriber and maintains the purchase information when the subscriber purchases specific content. The application server 130 may provide various types of call supplementary services according to types. For example, the application server 130 may provide a coloring service (providing music or video to a call connection tone), and the corresponding content may be a content DB ( 110).

The service system in the IMS-based network according to an embodiment of the present invention comprises a process of using a call service through an initial terminal registration process and a content purchase process. Each detailed operation will be described below.

It is assumed that user 1 has several terminals that must receive different numbers. For example, a user may have a portable terminal with a 010 number, a terminal with a 02 number at home, and a terminal with a 070 number for a Voice of Internet Protocol (VOIP), for convenience of description. This is an example and applies even if a user identifier is used. The new user identifier is registered in advance when the user opens the terminal in the form of ID, and one user uses one user identifier.

The registration process is performed based on the Session Initiation Protocal (SIP) protocol and transmits the corresponding information through the registration message among the SIP messages. In the registration message, the registration request target domain information and the sender's additional information are included in the message header, and the registration server authenticates it and returns a confirmation message. According to an embodiment of the present invention, the user identifier is specified in the information header of the identifier of the terminal in the registration message, and additionally the message is transmitted including the terminal type information, and the registration server 160 authenticates the user and as a result, Returns the number corresponding to the specific terminal type.

2 is a diagram illustrating a method in which a user registers a specific type of terminal to a network in an IMS-based network. Here, it is assumed that terminal 1 210 and terminal 2 220 are caller terminals, and terminal 3 300 is called receiver terminal.

Referring to FIG. 2, when a user applies power to the terminal 1 210 or explicitly logs in, the terminal 1 210 requests a registration including a user's personal identifier (ID) to the network. Transfer (S11). At this time, the terminal 1 210 transmits the necessary number type information together. The number type information is type information of a terminal and may indicate whether a mobile phone or a VOIP phone is present.

The registration request of the terminal 1 210 is delivered to the network and transmitted to the registration server 160 (HSS) through the call processing server 150 (P-CSCF or S-CSCF) that processes the registration request of the terminal (S13). At this time, the registration server 160 is stored in the subscriber information DB 14 in advance the number information to be allocated according to the user's personal identifier and the terminal type set in advance when the user subscribes to the service, the terminal 1 (210) After confirming the personal identifier and the terminal type with respect to the registration request, and returns the number corresponding to the corresponding user terminal 1 (210) through the call processing server 150 (S12). The phone number is included in the response message for the registration request, and may include, for example, corresponding information in the P-Associated-Identity header.

The terminal 1 210 stores the number returned from the network and recognizes that it can use it. According to the network / operator requirement, the terminal 1 210 may optionally perform an additional number registration procedure by re-registering the received number with the network again. In this case, the terminal 1 210 may confirm that it is normally registered after performing an additional number registration procedure, and the terminal 1 210 may be able to use a number assigned and confirmed from an initially set user identifier and network.

Subsequently, the user registers another type of terminal 2 (220) to which the user has subscribed through the same processes (S17, S16, and S17) as described above (S11, S13, and S12) and uses a number that can be used by the corresponding terminal from the network. Granted.

Even if there are more terminals, multiple terminals are registered and numbered through the same process.

In the above process, when the terminal performs the registration process in the network, the basic message may apply a Session Initiation Protocol (SIP) message defined in the IMS network. The SIP message consists of header information and a body, and the information required in the embodiment of the present invention is described in the header information of the SIP message. When the terminal transmits the registration request message to the network, the main information proposed in the embodiment of the present invention is user personal identifier and terminal type information. For example, the user personal identifier may be specified as a Unified Resource Identifier (URI) included in a SIP message transmitted from a terminal, and the terminal type may be added to the contact header of the SIP message. Can be specified as information. For example, if a domain.com subscriber registers abcd with his or her ID, each terminal designates sip: abcd@domain.com in the From header of the registration message and Contact: 'general contact information' in the Contact header; By adding a terminal type identifier such as description = 010 or description = mobile, the user information and the terminal type information are transmitted to the network.

After the registration process is normally performed, the terminal 1 210 of the user 1 maintains the identifier of the user 1 and the unique telephone number assigned to the terminal 1 210 therein, and the terminal 2 220 stores the user 1 therein. It maintains the personal identifier of and the unique telephone number assigned to the terminal 2 (220). Unlike the existing registration process based on the number, in the embodiment of the present invention, after registering the user personal identifier with the registration server 160 in advance, the registration server 160 receives a unique telephone number for each terminal. It is possible to find out which terminal the user is currently using.

After the registration process is performed, a process in which a user uses a service through a specific terminal will be described with reference to FIG. 3.

3 is a diagram illustrating a service method of a service system in an IMS-based network.

Referring to FIG. 3, user 1 may purchase content using his specific type of terminal 210. Examples of the content include a ringtone or coloring content, and the same procedure described later applies to the purchase of other types of content. When the terminal 1 210 accesses the content purchase server for content purchase, the user personal identifier embedded in the terminal 1 210 and a unique phone number of the terminal 1 210 are transferred together to the content purchase server 120 (S21). ). In this case, a method for delivering the information may be separately designated according to the content server 120 and the access protocol. For example, in the case of a web-based server, the terminal may transmit the information when the HTTP request message is transmitted from the terminal. It can be transmitted in addition. The content purchase server 120 may present an option at the time of content purchase. One option is to designate a use right to be used only on a specific terminal in a conventional manner, and the other option is that the content is based on user personal identifier information. It will also be available to all terminals. According to the user's selection, the corresponding content purchase information is stored in the content DB 110. At this time, the content application range is recorded to store whether the content is applied only to a specific terminal or is applicable / available in another terminal of the user 1. .

In particular, when the type of content is a download type such as a music file, the content purchase server 120 downloads the corresponding content to the terminal 1 (210) (S22). The scope of application of the right to download is available according to the content application information stored in step S21.

When the same user attempts to use the call service through the terminal 1 210, the corresponding information is transmitted to the network in the form of an invitation request (INVITE) message (S23). Sending an invitation request message generally means to make a call, but in an IMS-based network, other services may also be started through an invitation request message, and thus the application target of the invitation request message is not limited to call origination. The SIP-based invitation request message includes caller information and called party information, which typically specify a telephone number or ID assigned to the terminal. In an embodiment of the present invention, the invitation message includes a phone number assigned to the caller's terminal as the caller information and the caller personal identifier. The called party's information may be specified by the calling party, for example, may include a telephone number for the called party's specific terminal, or may include a called party identifier. In the case of including the called party identifier, the called party number search for the final incoming call is performed in the call processing server 150, and the corresponding number inquiry procedure follows the conventional method. For example, the sender identifier information included in the invitation request message may be included in the From header, and the number assigned to the specific terminal of the sender may be added to the P-Preferred-Identity.

At this time, the call processing server 150 checks the user's invitation request message and adds the caller identifier and the telephone number authenticated in the network to the SIP message header again (S24). The process of checking the validity of the invitation request message and adding the verified identifier follows a conventional procedure. However, in the embodiment of the present invention, the information to be added is not limited to one phone number, but a user (caller) personal identifier and a telephone. Adding the numbers together is a major difference. This information may be added using, for example, a P-Asserted-Identity header. Thereafter, the call processing server 150 confirms that there is an additional service required for call processing, and if necessary, transmits an invitation request message to the corresponding application server 130.

The application server 130 provides the caller identifier and the caller added by the call processing server 150 when providing a telephone number-based service, for example, coloring, multimedia CID, and various call additional services, to the invitation request message received by the application server. The information is identified using the number and the service is provided based on the number (S25).

For example, the caller-based call unit provides a service, for example, a multimedia CID is provided based on the caller's phone number, but according to an embodiment of the present invention, when the content is purchased based on the user according to the S21 process, the content is provided through user personal identifier information. Can be provided.

Thereafter, the call processing server 150 transmits the invitation request message to which the caller information is added to the called terminal 300 (S26), and the called terminal 300 receives the caller's user personal identifier and the phone number included in the message. And identify. If the calling party terminal 300 can only understand the calling party's telephone number, the calling party's telephone number may be provided as a CID, and in other cases, that is, if the calling party's identifier is available (for example, in advance of the called party's terminal). If you are registered as a messenger buddy or if you have registered the caller identifier in the phone number), you can use the information. If the caller personal identifier is registered as a buddy in the called terminal 300, it may show additional buddy information, a picture set by the caller, a phrase, and the like.

The invitation request message for the call is performed based on SIP, and typically includes call control information in a corresponding message header and media negotiation information in a body. Media negotiation information is not relevant to the embodiment of the present invention and necessary information is included in the header information. The header information of the invitation request message includes sender information and called party information. Conventionally, the caller's telephone number and the caller's telephone number have been designated as the corresponding information. However, in the embodiment of the present invention, the caller's personal identifier and the caller's telephone number are used as caller information. Apply optionally. In general, when attempting a telephone call, the telephone number of the called party is input. In this case, the called party information is designated as the telephone number. On the other hand, when the called party identifier is input, the corresponding information is recognized by the call processing server 150 and converted into an appropriate called party number. Since such a procedure is previously defined, the contents of the present invention are not described separately.

The process of extracting caller information in step S24 of the call processing server 150 will be described in detail as follows.

FIG. 4 is a diagram illustrating a user terminal identification processing method of the IMS call processing server in FIG. 3.

Referring to FIG. 4, the call processing server 150 determines whether to connect a call or provide a service through a message received from the terminal.

First, the call processing server 150 first receives a message transmitted from the terminal 1 210 and checks an identifier (usually a SIP URI) included in the From header (S41).

Thereafter, the call processing server 150 checks whether additional identifier information is included in the message, and whether the terminal 1 210 is a terminal conforming to an old SIP standard or a terminal according to an embodiment of the present invention through a corresponding process. Judge. For example, if a message includes a phone number in a P-Preferred-Identity header, the call processing server 150 performs S43 to further analyze the message. In contrast, in general, the identifier is processed according to S44.

In the case of the terminal to which the embodiment of the present invention is applied, the caller identifier information and the caller's telephone number may be distinguished by checking the header information of the invitation request message. For example, the TEL URI included in the P-Preferred-Identity header may be classified as a terminal identifier, and the SIP URI of the From header may be regarded as a user identifier. Then, after determining whether each URI is valid based on the information authenticated by the registration server 160, and adding the corresponding information to the header again, the server or the receiver receiving the corresponding message processed by the call processing server 160 after the S45 process. The terminal can identify the user and the terminal requesting the service.

In the case of the terminal complying with the old SIP standard, only the identifier included in the From header can be checked (S44). Typically, the identifier information is designated as the caller's telephone number, and the server includes only the information in the P-Asserted-Identity header.

With the identifier information extracted in the above process, the call processing server 150 adds the confirmed information to the message header again after checking the validity of the identifier (s) (S45). Then, when the corresponding message is delivered, the application server 160 uses a user identifier for a subscriber-based service, for example, content, and the like, and uses a phone number to provide a service for a terminal / number-based service, for example, coloring and other calling units. . If there is only one identifier, it follows the conventional method provided.

In order for the embodiment of the present invention to operate properly, the terminal may have prefix information on a number it can receive in the operator authentication process, for example, '010' for a mobile / mobile terminal, and an area for a home household terminal. Accordingly, the terminal type information such as area code (02, 042, etc.) and '070' in the case of the VoIP terminal are included therein. The terminal authenticated by the operator undergoes a registration / opening process when the subscriber uses it. The operator issues a unique ID, which is a user's personal identifier, for each user, and assigns an actual telephone number available for each terminal type. At this time, a unique ID is unique to the same user, and a number is specified differently for each terminal type.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation may be easily implemented by those skilled in the art from the description of the above-described embodiments. In addition, the embodiment of the present invention is not limited to the IMS network but may be applied to other networks.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

As described above, in the embodiment of the present invention, the terminal registration procedure, service provision procedure and method applicable to a user to receive a service using various types of terminals in an IMS-based network have been described. Accordingly, it is easy to apply and use an existing number or a newly assigned number for each terminal type in the user's position, and the service provider can distinguish the identifier according to the type of service to be provided by identifying the user and the terminal information together. Accordingly, a user can receive a user-based service regardless of various terminal types. In addition, the present invention is easy to apply the system and method for identifying the user and the terminal by applying and applying the IMS infrastructure and call control protocol widely applied in the third generation network.
