Description

Method and System for Providing Call Back Number Service in WCDMA Communication System

The present invention relates to a method and system for providing a callback number in a wideband code division multiple access (WCDMA) system. More specifically, the TP-PID (Transfer Protocol-Protocol Identifier) value and the user data header (Header) in the short message service of Short Message Service (SMS) defined in the conventional WCDMA mobile communication system. The present invention relates to a method and a system in which various callback numbers can be provided in a WCDMA system by providing a coding and decoding function of user data by additionally defining a value).

Since the Internet communication service, which is symbolized by the World Wide Web, has been in the spotlight, communication service has already made a big difference in human life in all aspects of society, economy and politics. It is hard to imagine life without the Internet, and the Internet is a part of life. Therefore, in recent years, the use of various high-speed communication networks, such as in order to use a variety of communication services in a better environment has increased significantly.

However, communication services such as the Internet using a computer have advantages in that the transmission speed is high and data input is convenient. However, communication services such as the Internet can no longer be used once the computer is out of the environment. It has the disadvantage of using the service.

Therefore, in recent years, many telecommunication companies have spurred the development of new technology called wireless Internet to provide communication services such as the Internet beyond the space. Wireless Internet refers to an environment and technology in which a user can use an Internet service through a wireless network while using a mobile communication terminal. The development of mobile communication technology and the rapid increase in the penetration rate of mobile communication terminal further promoted the development of this wireless Internet environment.

Thanks to the development of the wireless Internet environment, mobile operators and other telecommunication operators are further promoting the use of the wireless Internet by providing various and useful services to the users of the wireless Internet. Such wireless Internet services include text messages, e-mails, cards, letters, games, geography / life information, learning, cartoons, and the like.

In particular, the short message service refers to a service for transferring a text message of limited length from a computer connected to the Internet to a mobile communication terminal or between mobile communication terminals regardless of whether a mobile subscriber is in a call state. The short message service that can transmit texts of about 80 bytes (80 Korean characters) on the LCD screen of mobile communication terminals has exploded in utilization due to the wide range of use from personal use to corporate use. to be. In other words, the recent SMS goes beyond simple interpersonal message transmission, and can be used for group transmission, reservation transmission, email arrival notification, personal information management, stock information notification, product information notification, financial information notification, and callback number service. It is widely used for various purposes.

Here, the callback number transmission in the short message service not only transmits the caller's phone number but also transmits specific URL (Uniform Resource Locator) address information for wireless Internet access so that the receiver of the short message is transmitted to the mobile terminal. It also provides a function to automatically access a wireless Internet web page with the URL by pressing a specific button.

However, as the mobile communication system evolves, related standards for short message services must be newly defined according to the evolutionary path. That is, according to whether the current 2G (2.5G) or 2.5G (2.5G) mobile communication system is evolving into synchronous 3G (CDMA 2000) or asynchronous 3G (WCDMA), it is appropriate to meet the specification for short message service. It must be newly defined.

Currently, the WCDMA communication method is a radio protocol recommended by IMT-2000, and is being provided or prepared for by many communication service providers around the world. W-CDMA systems have a high call quality and use a spread spectrum method, which is suitable for transmitting a large amount of data. The WCDMA system adopts 32 Kbps Adaptive Differential Pulse Code Modulation (ADPCM) for voice coding, and supports high mobility enough to make a call even if the user moves at a speed of about 100 km / h. In addition, WCDMA communication is adopted by most countries, and many institutions such as Korea, Europe, Japan, USA, and China have formed 3GPP (3rd Generation Partnership Project) to develop technical specifications for WCDMA. have.

However, the short message service related standard defined in the current WCDMA scheme is only related to the transmission of a simple short message. Therefore, the current WCDMA communication system does not provide a callback number service related to a caller's telephone number, a specific URL access function, and the like provided by a short message service of 2G or 2.5G. Accordingly, there is a problem in that it does not provide various and convenient functions to mobile communication subscribers using the WCDMA system and is not connected with 2G or 2.5G services.

In order to solve the above problems, the present invention additionally defines the TP-PID and the user data header value in the short message standard of the short message service defined in the mobile communication system using the conventional WCDMA scheme to encode and decode user data. It is an object of the present invention to provide a method and system for providing various callback number services in a WCDMA system by providing a function.

The mobile communication terminal 110 is a terminal that uses a short message service through a circuit switched network (CSN) and a packet switched network (PSN), and performs packet data communication using an asynchronous WCDMA network as a packet network. Voice call is performed using IS-95B (Interim Standard-95B) network. Of course, the mobile communication terminal 110 according to the embodiment of the present invention is a hybrid access terminal (HAT) that supports both the IS-95B system and the WCDMA system.

In addition, the mobile communication terminal 110 stores a predetermined program for generating a short message including the callback number in WCDMA or decoding the short message including the received callback number in a method according to the technical idea of the present invention. have. On the other hand, the mobile communication terminal according to an embodiment of the present invention includes a mobile phone, PDA (PDA) and the like.

The wireless base station 120 includes a Radio Transceiver Subsystem (RTS) 122 and a Radio Network Controller (RNC) 124 with an additional function for supporting WCDMA in an existing IS-95B system. . The RTS 122 performs a wireless access termination function with the mobile communication terminal 110 according to the 3GPP wireless access standard, and transmits and receives voice, video, and data traffic in a WCDMA manner, and a mobile communication terminal through a transmit / receive antenna. Transmit and receive information with 110. In general, the internal subsystem of the RTS 122 is composed of a Base Station Interconnection Subsystem (BIS), a Base Band Subsystem (BBS) and a Radio Frequency Subsystem (RF).

The wireless control station 124 is wired or wireless channel management, mobile communication terminal 110 protocol matching, base station protocol matching. It is responsible for functions such as soft handoff processing, core network protocol processing, GPRS (General Packet Radio Service) access, fault management, and system loading. Here, GPRS is an asynchronous communication system that supports a data transmission rate of 115 Kbps, provides a multimedia mail, and maximizes the efficiency of a transmission line by packet data transmission.

The mobile switching center 130 will have a soft switching structure to speed up call processing in addition to the basic functions for voice call in the existing IS-95B network. Here, soft switching is a technology capable of processing voice, data, and video signals with a high speed packet switch by upgrading a circuit switch of a conventional exchange to a software switch.

The visitor location register 132 registers and manages location information of the mobile communication terminal 110 coming into the jurisdiction of the mobile switching center 130 and transmits the newly acquired location information of the mobile communication terminal 110 to the mobile communication terminal 110. The home location register (160). In addition, while taking over and managing a copy of the profile information of the mobile communication terminal 110 received from the home location register 160, the function of utilizing the location control, call processing, external operation processing of the mobile communication terminal 110, etc. Do this. Here, the profile information refers to a mobile identification number (MIN), an electrical serial number (ESN), and registered service information of the corresponding mobile communication terminal 110. In FIG. 1, the visitor location register 132 is separately installed outside the mobile switching center 130 for convenience of description. However, the visitor location register 132 is generally installed inside the mobile switching center 130. to be.

The SGSN 140 has a hardware structure for providing an Asynchronous Transfer Mode (ATM) -based switch and routing connection for a GPRS service, and supports an operating system (OS) according to various data service processes. The operating system's functions consist of GPRS mobility management, GPRS session management, GPRS authentication, and billing functions.

The GGSN 150 is a serving node of an Internet Protocol (IP) -based packet network that provides a high-speed packet data service for GPRS data service. The GGSN 150 provides mobility of packet data service and performs various data related protocol processing functions. And a packet data network 192. In addition, the GGSN 150 provides address assignment, domain address change, billing information, and maintenance functions.

The home location register 160 receives the location information of the mobile communication terminal 110 from the visitor location register 132 and performs functions such as registration recognition, registration deletion, and location verification. In addition, the home location register 160 obtains profile information of the mobile communication terminal 110 from the home location register to which the mobile communication terminal 110 is initially subscribed using the location information received from the visitor location register 132. In addition, the home location register 160 checks the connection status of the mobile communication terminal 110 that is registered to the location of the mobile terminal 110 to check whether the Idle mode or Active (active) mode, Active In mode, it is continuously checked whether it is connected to the circuit network or the packet network.

The SMS-GMSC 170 receives a short message transmitted from the SMSC 180 and sets a path for transmitting the short message to the transmission target mobile communication terminal 110 through a packet network or a circuit network. Message service gateway. That is, the SMS-GMSC 170 inquires the network connection information of the mobile communication terminal 110 to be transmitted to the home location register 160 having the location information and the network connection information of the mobile communication terminal 110 and responds to the response result. The short message thus received is transmitted to the mobile switching center 130 of the circuit network or the SGSN 140 of the packet network.

Meanwhile, although SMS-GMSC 170 is illustrated as a short message service gateway in FIG. 1, an SMS-IWMSC (Inter Working Message Service Center) is also possible.

The SMSC 180 receives a short message transmitted from the mobile communication terminal 110 or the connected SMS server 190 and the MIN of the called mobile communication terminal. When the SMSC 180 receives the acknowledgment signal of the short message transmitted from the mobile communication terminal 110 from the line network or the packet network, the SMSC 180 sets the state of the stored short message to 'SENT' and then deletes it after a certain period of time. That is, the SMSC 180 temporarily stores the received short message and stores the short message periodically at predetermined time intervals.

Meanwhile, the SMSC 180 according to an embodiment of the present invention supports the transmission of a short message to which various callback numbers are added in the WCDMA scheme using the data encoding method defined in the embodiment of the present invention. A method for adding a callback number to a short message according to an embodiment of the present invention will be described in more detail with reference to FIG. 3.

Meanwhile, the SMSC 180 receives a short message transmitted from the mobile switching center 130 or the SGSN 140 and MIN information of the target mobile communication terminal 110 so that the corresponding mobile communication terminal 110 is set to a certain mode. The SMS server 190 queries whether the short message service including the callback number is supported. The SMSC 180 receives the response message transmitted from the SMS server 190 and checks whether the short message service including the callback number is supported in the transmission target mobile communication terminal 110 and whether it is operating in which mode. It is determined whether the short message including the number can be transmitted and which network of the circuit network and the packet network is to be transmitted.

Accordingly, the SMS-GMSC 170 receives a short message including mode information (line network connection, packet network connection, Idle status, etc.) of the mobile communication terminal 110 from the SMSC 180, and receives the short message through the corresponding network. In step 110, the received short message is transmitted.

The SMS server 190 receives a short message creation request signal transmitted from another connected server, creates a short message, and transmits the short message to the SMSC 180. Also, the SMS server 190 checks whether the transmission target mobile communication terminal 110 can use the short message service including the callback number by using its own database or connected home location register 160. do. That is, the home location register 160 receives a query message regarding whether the callback number service of the mobile communication terminal 110 is available from the SMS server 190 and maintains a query message of the mobile communication terminal 110. The profile information is retrieved and a response to whether the callback number service is available is transmitted to the SMS server 190.

2 is a diagram showing the structure of a protocol defined for short message service in 3GPP.

As can be seen from FIG. 2, protocols defined for short message service in 3GPP are SM-LL (Short Message-Link Layer), SM-RL (Relay Layer), SM-TL (TransferLayer), and SM-AL (Application Layer). ) And the like. In addition, in FIG. 2, a short message entity (SME) refers to a mobile communication terminal or a server for transmitting and receiving a short message.

The short message service protocol defined by 3GPP is transmitted on a paging channel or a forward traffic channel for a forward channel, and an access channel for a reverse channel. In addition, it is transmitted as a data burst message of a reverse traffic channel. In addition, when a user is in a call, the user is operated in a multiplex mode that enables data transmission during a voice call.

Data Burst Message is transmitted and received to the SM-LL, and the SM-RL functions to set a transmission channel according to the state of the mobile communication terminal (Idle Mode, Traffic Mode, etc.) and the message length. In addition, the SM-RL receives the message of the SM-TL and transmits it to the relay point or the end point indicated by the next stage, and if the message is not transmitted to the next relay point or the endpoint. Generates and sends an error message with SM-TL.

SM-TL basically establishes a peer-to-peer connection between the SMSC that generates the message and the mobile station (MS), receives the short message parameter from the SM-AL, composes the message, and configures the configured message. It transfers to SM-RL. In addition, a short message is received from the SM-RL, and the received short message is transferred to the SM-AL. The messages of SM-TL include Teleservice Identifier, calling party number, Bearer Reply Option, and bearer data to distinguish services such as voice mailbox and general message.

SM-AL transmits the destination address to SM-TL when the mobile terminal sends the SMS User Ack Message, and when the message received by the mobile terminal is the SMS Deliver Message, the Relay option is disabled. When set, it transmits the fact to the mobile communication terminal. The SM-AL consists of user data containing the contents of the received message, whether the short message is confidential, a message arrival notification, and a language delimiter.

3 is a diagram illustrating a format of user data in SM-AL defined in 3GPP.

Referring to each component (element) shown in FIG. 3, UDL (User Data Length) is the total length of user data, UDHL (User Data Header Length) is the total length of the user data header, and information (IEI) Element Indicator (IE) is an indicator indicating that information starts, IEIDL (IEI Data Length) is a data length of IEI, and Information Element Data (IED) represents data actually transmitted. That is, the UDL element to the IEDn element is a user data header. Therefore, the SM (8 bit data or UCS-2 data) element following the user data header contains the actual content of the message.

According to the technical idea of the present invention, a specific range of values are set in a TP-PID (TP-Protocol Identifier) used for a short message format to predefine that data transmitted and received is used for a specific purpose. Here, the TP-PID has an 8-bit value as a protocol indicating a parameter of an upper layer. That is, the mobile communication terminal 110 or the SMSC 180 that transmits and receives the short message checks the TP-PID value included in the short message and determines that the short message is used for a specific purpose, or uses the message for a specific purpose. Short messages are generated by allocating a predefined specific TP-PID value for use as a.

In addition, according to the technical idea of the present invention, to implement the short message service including the callback number using the TP-PID value defined for the purpose of a specific short message service by specifying the IEI of the above-described user data header callback number Defines that it is a short message containing. According to an embodiment of the present invention, if the value of IEI is FE (Octets), it indicates that a callback number is included in the short message. Of course, the value of the IEI for the callback number service may be changed at any time.

Accordingly, the mobile communication terminal 110 first decodes the value of the TP-PID included in the received short message, recognizes that the message is used for a specific purpose, and then decodes the IEI value of the user data header to decode the short message. Check that the callback number is included in the. In addition, the mobile communication terminal 110 or the SMSC 180 generating the short message adds a value set for the specific purpose to the TP-PID in order to generate the short message to which the callback number is added, and the callback to the IEI of the user data header. Assigns a specific value (FE) set in the number service.

Meanwhile, in FIG. 3, IEDa includes Data Codec Scheme (DCS) information on a callback number. That is, the mobile communication terminal 110 that receives and decodes the short message including the callback number may know what data format the callback number is configured by using the DCS information included in the IEDa. According to an embodiment of the present invention, if 7 bits to 5 bits of the DCS are 000, the callback number is a number (for example, a telephone number, etc.), and if 001 is a URL coded with Group Special Mobile (GSM) 7, 010 is UCS URL coded with (UniCode System) 2, and 011 indicates URL coded with ASCII. Meanwhile, the remaining values 100, 101, 110, and 111 are left in a reserved state in consideration of future scalability.

On the other hand, although not shown in Figure 3, elements above the IEDb includes a callback number. The callback number according to an embodiment of the present invention may be URL information of English or Korean composed of numbers and various data formats. Therefore, the mobile communication terminal 110 that receives and decodes the short message including the callback number decodes the callback number included in the element of IEDb or more, and displays the callback number on the LCD screen. If the key value related to the connection connection of is inputted, try to make a call to the displayed phone number or try to connect to the Internet using a URL address.

4 is a flowchart illustrating a process of creating and sending a short message including a callback number in a mobile communication terminal 110 according to an embodiment of the present invention.

According to an embodiment of the present invention, the user selects a menu for creating a short message using a key button of the mobile communication terminal 110 capable of using the callback number service (S400).

The user inputs a predetermined short message using a key button on the short message input screen displayed on the mobile communication terminal 110 (S402). The user who has completed the input of the short message in step S402 determines whether to input a callback number (S404).

The user inputs a predetermined callback number using a key button, and inputs an origination key of a short message including the callback number (S406). When the short message and the callback number are input by the user, the mobile communication terminal 110 allocates a specific service TP-PID value and an IEI value for the callback number service to the short message to be sent (S408).

The mobile communication terminal 110 transmits a short message including a TP-PID value and an IEI value for callback number service in step S408 (S410). If the callback number input menu is not selected by the user in step S404, the mobile communication terminal 110 encodes only the input short message by the existing short message service providing method and proceeds to step S410.

The short message transmitted from the mobile communication terminal 110 is transmitted to the UTRAN 120 and the SMSC 180, and the UTRAN 120 and the SMSC 180 which successfully receive the short message transmit the acknowledgment response message to the mobile communication terminal. Transmit to 110 (S412). The mobile communication terminal 110 that has received the acknowledgment response message from the UTRAN 120 and the SMSC 180 returns to the standby state (S414).

5 is a flowchart illustrating a process of processing a short message including a callback number sent from a mobile communication terminal 110 in a WCDMA network according to an embodiment of the present invention.

The short message including the callback number generated by the originating terminal through the process described with reference to FIG. 5 is transmitted to the MSC 130 via the UTRAN 120 (S500). Of course, in FIG. 5, the short message transmitted from the originating terminal is illustrated as being transmitted to the MSC 130. However, as described in FIG. 1, the short message transmitted from the originating terminal may also be transmitted to the SGSN 140. This is determined by the RNC 124 of the UTRAN 120 to determine which network to send the short message to by determining whether the originating terminal is using the circuit network service or the packet network service when sending the short message. Is done.

Upon receiving the short message from the originating terminal, the MSC 130 transmits the short message received to the SMSC 180 (S502). The SMSC 180, which has normally received the short message transmission request from the MSC 130, transmits an outgoing response signal to the MSC 130 (S504), and the MSC 130, which has received the outgoing response signal from the SMSC 180, also receives the request. The outgoing response signal is transmitted to the calling terminal (S506).

In addition, the SMSC 180, which has normally received the short message transmission request from the MSC 130, inquires of the SMS server 190 whether the receiving terminal can use the short message service including the callback number (S508). .

Upon receiving an inquiry related to the availability of the short message service including the callback number of the receiving terminal from the SMSC 180, the SMS server 190 receives the receiving terminal stored in a built-in database or connected home location register 160. Search the profile information of S to search whether the short message service including the callback number is available (S510).

The SMS server 190 transmits a search result of whether the call back number service of the receiving terminal is supported in the step S510 to the SMSC 180 (S512). SMSC 180 notified from SMS server 190 that the receiving terminal is a terminal capable of using the short message service including the callback number transmits the received short message to the receiving terminal via a circuit network or a packet network, and the receiving terminal transmits the received short message. The incoming short message is received (S514).

The receiving terminal receiving the short message decodes the short message including the callback number by the method described with reference to FIG. 3 and displays the short message on the LCD screen (S516). In addition, the receiving terminal receiving the short message notifies the SMSC 180 that the reception is normally completed, and the SMSC 180 receiving the receiving response signal from the receiving terminal changes the state of the short message to 'SENT'. If a predetermined time elapses, the control deletes the data (S518).

6 is a flowchart illustrating a process of processing a request for transmission of a short message including a callback number requested by an SME in a WCDMA network according to an embodiment of the present invention.

A request for transmission of a short message including a callback number from a specific SME (eg, a server) to a receiving terminal is transmitted to the SMS server 190 (S600). Upon receiving a request for transmitting a short message including a callback number from a specific SME, the SMS server 190 transmits a short message transmission request signal to the SMSC 180 (S602).

The SMSC 180, which has received the transmission request signal of the short message including the callback number from the SMS server 190, assigns a predetermined TP-PID and an IEI value for the callback number service to the received short message as described in FIG. After the encoding, the short message encoded by the MSC 130 is transmitted (S604).

Upon receiving the short message from the SMSC 180, the MSC 130 checks the location registration information of the receiving terminal in the home location register 160 or the visitor location register 132 to determine the location of the receiving terminal. The short message is transmitted to the RNC 124, and the UTRAN 120 transmits the short message to the corresponding receiving terminal (S606).

In step S606, the receiving terminal receiving the short message including the callback number decodes the short message encoded by the method described with reference to FIG. 3, and displays the content of the short message and the information of the callback number on the LCD screen (S608). Of course, the receiving terminal successfully receiving the short message transmitted from the MSC 130 transmits a reception confirmation signal to the MSC 130 (S610), the MSC 130 transmits to the SMSC 180 (S612), The SMSC 180 transmits to the SMS server 190 (S614).

Of course, although FIG. 6 describes the processing of the short message service including the callback number in the circuit network, the short message service is smoothly performed by the SGSN 140 performing a function similar to the MSC 130 in the circuit network in the packet network. Is processed.

7 is a flowchart illustrating a process of receiving and processing a short message including a callback number in the mobile communication terminal 110 according to an embodiment of the present invention.

First, the mobile communication terminal 110 receiving the short message maintains a normal standby state capable of receiving the short message (S700). In the normal standby state, the mobile communication terminal 110 receives a short message transmitted from the RTS 122 (S702).

The mobile communication terminal 110 receiving the short message decodes and analyzes the TP-PID value and the user data header value included in the short message (S704). The mobile communication terminal 110 determines whether the callback number is included in the short message as a result of the analysis in step S704 (S706).

As a result of the determination in step S706, when it is determined that the short message includes the callback number, the mobile terminal 110 decodes the callback number using the DCS information included in the user data header (S708).
