Abstract

PURPOSE: A method and system for processing message transmission between a CDMA network and a GSM network is provided to transmit messages interactively between a CDMA network and a GSM network. CONSTITUTION: If a CDMA subscriber makes out and transmits a message, the message is transmits to a CDMA MSC. The CDMA MSC transmits an SMDPP(Short Message Delivery Point-Point) message containing the received message to an ISMSC(Integrated Short Message Service Center)(310). Receiving the SMDPP message, the ISMSC transmits an SMDPP Ack Message to the CDMA MSC(315). The ISMSC confirms the destination number contained in the SMDPP message and judges whether the terminal to receive the first message is a GSM terminal(320). In case that the destination terminal is a GSM-subscribed terminal, the ISMSC transmits an SRI(SendRoutingInfoSM) message to a GMSC(Gateway MSC) of a GSM network in order to confirm the location of the destination terminal(325). An HLR in the GSM network grasps the location information of the destination terminal and transmits an SRI Ack Message, including the location information, to the GMSC(330). The GMSC transmits the location information to the ISMSC(335).

Description

METHOD AND SYSTEM FOR PROVIDING MESSAGING SERVICE BETWEEN CDMA NETWORK AND GSM NETWORK}

The present invention relates to a message transmission method of a mobile communication terminal, and more particularly, to a method and system for transmitting a message in both directions between a CDMA network and a GSM network.

Currently, the SMS message interworking method between the GSM network and the CDMA network has a different standard. For this reason, when using the SMS service, the SMS service is not provided to the G / W system by using a protocol (TCP / IP) arbitrarily defined between operators, or SMS service is not provided between these service providers.

In the case of CDMA, when subscriber A sends a message to subscriber B, the subscriber A terminal first transmits the message, and the exchange in the area where subscriber A is located receives the message. When the exchange receives the message, it checks the destination number (subscriber B) of the message and transmits a SMDPP message (Short Message Delivery Point-Point Message) to the home SMSC (Short Message System Center). Here, the Home SMSC refers to a specific SMSC classified according to the called number, which occurs because the mobile communication service provider designates and uses the SMSC according to the called number. The SMSC system receives a SMDPP message from an exchange, and in case of a normal message, transmits an SMDPP acknowledgment message and, in the case of an abnormal message, an error code in a SMDPP NAK message. Next, the transmission failure is displayed on the terminal A's terminal screen. The SMSC system sends an SMSREQ message to the HLR (Home Location Register) to which the called number belongs, and the received HLR system accepts the called number of the message and sends the location information (MSC information) of the subscriber to the SMSREQ Ack. Send it in a message. If subscriber B's terminal is in the state of 'POWER OFF', the information 'POWER OFF' is transmitted to the SMSREQ Ack information. The SMSC system acquires MSC information (MSC A) from the HLR, generates a SMDPP message, transmits it to the exchange (MSC A), and receives the message from the terminal, and receives the success success message. The exchange sends a SMDPP Ack (SMDPP) message to the SMSC system. The SMSC system generates charging data after the terminal successfully receives the message. The billing is charged only when the message is successfully received through this process.

In the case of GSM, the following process is performed.

First, the sender composes and transmits an SMS message to the mobile communication terminal, and the sending MSC (Mobile Switching Center) transmits the message to the SMSC through a FSM message (ForwardSM Message). When the SMSC receives a normal message, it transmits a FSM Ack message (ForwardSM Acknowledge Message), and in case of an abnormal message (parametererror, encoding error), etc., the FSM NAK message. If the SMSC has received a normal message, it indicates to the calling terminal that the message was successfully sent so that the user can know. The SMSC sends an SRI message (SendRoutingInfoSM Message) to the HLR that accepts the incoming call to query the called party's location. The HLR sends an SRI Ack message (SendRoutingInfoSM Acknowledge Message) to the SMSC to transmit the location information of the called party (information of the called party MSC corresponding to the called party). The SMSC sends the FSM message to the called MSC and the called MSC sends the message to the called terminal. The Ack value of message success is transmitted to the terminal to the exchange, and the destination MSC sends an FMS Ack message to the SMSC. The SMSC system generates the charge only for the successful transmission of the message.

In order to provide an SMS service to subscribers of an existing GSM mobile carrier, a new mobile operator providing a CDMA service uses the following G / W system.

1 is a diagram illustrating a network connection for performing a message transmission process between a CDMA network and a GSM network according to the prior art, and FIG. 2 is a view for explaining a method of using an SMS service between GSM operators in a GSM network according to the prior art. A diagram illustrating a network connection.

As shown in Figure 2, using the SMS service between GSM operators in the GSM network goes through the following process. First, the subscriber A terminal transmits an SMS message to the subscriber B terminal. Next, the MSC of GSM # 1 receives the message and the MSC of GSM # 1 sends the message to the SMSC via the FSM message. When the SMSC receives the normal message, it sends a FSM Ack message to the MSC of GSM # 1. SMSC sends SRI message to GMSC of GSM # 1. Next, the SRI message is transmitted from GMSC of GSM # 1 to GMSC of GSM # 2. Sends SRI message from GMSC of GSM # 2 to HLR of GSM # 2 and receives SRI Ack message. The GMSC of GSM # 2 receives the SRI Ack message and transmits the SRI Ack message to the GMSC of GSM # 1. GMSC in GSM # 1 sends SRI Ack message to GSM # 1 SMSC, SMSC in GSM # 1 sends FSM message to GMSC in GSM # 1, GMSC in GSM # 1 sends FSM message to GSM # 2 GMSC . Next, after sending the FSM message from the GMSC of GSM # 2 to the MSC of GSM # 2, and the subscriber B of GSM # 2 receives the message, the MSC of GSM # 2 sends the FSM Ack message to the GMSC of GSM # 2. . Next, the GMSC of GSM # 2 receives the FSM Ack message, sends the FSM Ack message to the GMSC of GSM # 1, and the GMSC of GSM # 1 sends the FSM Ack message to the SMSC of GSM # 1. Billing data is generated only for successful messages in SMSC of GSM # 1.

When the SMS message is transmitted from the GSM provider # 1, the message is stored in the SMSC system of the GSM provider # 1. When sending a message to the subscriber of GSM provider # 2 If the terminal does not receive the message, such as the shadow area, the terminal POWER OFF, the message is pending in the SMSC system of the GSM provider # 1. When the terminal of the GSM provider # 2 can receive the message, the SMSC of the GSM provider # 1 retransmits the message and performs a charging function for the successful message.

As shown in FIG. 1, in a structure using a G / W system, when a message is transmitted from a CDMA G / W to a GSM G / W, the GSM G / W gives a response to the message reception. The SMSC system of the CDMA network performs the charging function regardless of whether the GSM subscriber has received the message. That is, the information on whether the receiving user has normally received the message is not transmitted to the SMSC of the CDMA network, and only the message is received in the GSM G / W. Regardless of which billing is performed. Therefore, even when the subscriber of the GSM network does not receive a message, there is a problem in that a charging mismatch phenomenon occurs in which the charging is performed to the sender sent by CDMA. According to the related art, charging is generated regardless of whether the receiving user receives the message normally even when transmitting the message from the CDMA network to the GSM network as well as transmitting the message from the GSM network to the CDMA network. There is a problem.

SUMMARY OF THE INVENTION The present invention has been made to improve the prior art as described above, and an object thereof is to provide a method and apparatus capable of transmitting a message in both directions between a CDMA network and a GSM network.

It is still another object of the present invention to provide a method and apparatus for resolving a mismatch on billing generated when a message is transmitted between an existing CDMA network and a GSM network.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

3 is a flowchart illustrating a message transmission from a CDMA network to a GSM network according to an embodiment of the present invention.

First, a CDMA subscriber creates a message using a subscription terminal and transmits it. The message is transmitted to a CDMA Mobile Switching Center (CDMA MSC), which receives the CDMA mobile switching center, in step 310, a SMDPP message including the created first message according to the present invention. Send to an Intergrated Short Message Service Center (ISMSC) (step 310). The internal configuration of the integrated message center (ISMSC) is described in detail later with reference to FIG. The first message becomes bearer data of the SMDPP message. In step 315 the ISMSC sends a SMDPP Ack Message to the CDMA mobile switching center in response to receiving the SMDPP message.

In step 320, the ISMSC checks the called number included in the SMDPP message to determine whether the terminal receiving the first message is a GSM terminal. Whether the terminal is joined to the GSM network or the terminal to the CDMA network can be determined from the called number (telephone number) because the telephone numbers are distinguished according to the subscription network.

In step 320, when the called terminal is a GSM subscriber station, a SendRountingInfoSM message for knowing the called party's location is transmitted to a gateway MSC of a GSM network. When the called terminal receiving the first message is a CDMA terminal of the same kind, the first message may be delivered without a predetermined conversion process, but in the case of a GSM terminal, the first message should go through a predetermined conversion process. In step 310, the SMDPP message received by the ISMSC includes the terminal number of the called party that receives the first message. Through this, the called party terminal number may be extracted to check whether it is a GSM terminal or a CDMA terminal. In operation 315, the ISMSC may transmit a SMDPP Ack message to the CDMA mobile switching station in response to receiving the SMDPP message.

In the next step 330, the HLR of the GSM network grasps the location information of the terminal of the called party to receive the message and transmits the location information to the gateway mobile switching center (GSMC) through an SRI response message (SendRoutingInfoSM Ack Message). GMSC transmits location information received from HLR of GSM network to ISMSC.

In step 340, the ISMSC system transmits the ForwardSM message (FSM) according to the GSM standard to the exchange in which the called party is located, and the message transmitted from the transmitting terminal is transmitted to the receiving terminal (Msg Send). The receiving terminal then sends an acknowledgment of receipt to the receiving MSC.

In step 350, the receiving MSC sends an FSM response message to the GMSC. The GMSC again sends the FSM response message to the ISMSC. In response to receiving the FSM response message, the ISMSC confirms whether the message has been received at the called party's terminal and generates charging data. The FSM includes a second message obtained by converting the first message into a GSM scheme, and the second message becomes TPDU data of the FSM message. The conversion from the first message to the second message will be described later in detail.

The charging data is made by receiving a FSM response message from the gateway mobile switching center (GSMS) and confirming that the second message, which is converted into the GSM scheme and transmitted, is transmitted to the called party's terminal. If the second message is not normally sent to the called terminal, charging is not made.

4 is a diagram illustrating a flow of converting a first message into a second message according to an embodiment of the present invention.

First, in step 410, user data of bearer data is converted into TP user data of TPDU data.

In a next step 420, a message center time stamp of the bearer data is converted into a TP service center time stamp of the TPDU data.

In step 430, the callback number of the bearer data is converted into a TP origination address of the TPDU data, and in step 440, a language indicator of the bearer data is converted into the TP data of the TPDU data. Convert to TP Data Coding Scheme.

CDMA and GSM have different specifications, and different parameters are used. There is no exact match between the CDMA and GSM MAP values. Since the basic concept for serving a user is the same, parameters used in the same concept can perform a conversion function. Parameters used for other purposes are not matched because both CDMA and GSM networks have different functions. In the present invention, rather than using the CDMA MAP and GSM MAP to match each other can be referred to as a function that supports two different network MAP functions together.

5 is a flowchart illustrating a message transmission from a GSM network to a CDMA network according to an embodiment of the present invention.

First, a GSM subscriber composes and transmits a first message in a GSM network. Next, a SendRoutingInfo SM message (SRI message) is transmitted from the gateway MSC (GMSC) of the GSM network receiving the first message to the ISMSC. The SMSC system extracts the called number from the first message and determines whether the terminal of the extracted called number is GSM or CDMA. In the case of the CDMA method, the SendRoutingInfoSM message is transmitted to the ISMSC system of the CDMA network to inquire the location information of the called party. At this time, the ISMSC system converts the SRI message including the first message into an SMSREQ message because the SRI message is written in the GSM method and cannot be read by the difference between the specification and the parameter value in the CDMA HLR server. Thus, the ISMSC converts the value of the msisdn parameter included in the SRI message into the value of the MIN parameter included in the SMSREQ message so that it can be read by the HLR of the CDMA network.

The HLR server inquires the location of the called terminal and transmits an SMSREQ Ack Message including the location information of the called terminal to the ISMSC. The ISMSC system inquires an SMSREQ message, which is a CDMA standard, to the HLR system of the CDMA network and transmits the corresponding location information to the gateway mobile switching center (GMSC). The SMSC system receives the first message to the ISMSC system. The ISMSC system receives the first message and transmits a SMDPP message including a second message obtained by converting the first message to a CDMA method to a corresponding exchange, and when the called party normally receives the second message, a gateway mobile switching center ( GMSC) checks this to generate billing data, and whether or not it is received can be known by receiving the FSM response message. The SMREQ response message may be converted into an SRI response message by setting a predetermined fixed value to the IMSI parameter value of the SRI response message. In addition, when receiving an FSM message from the gateway mobile switching center (GMSC), first converts the FSM message into a SMDPP message, and transmits the SMDPP message to a mobile switching center (MSC) associated with the location of the called terminal and the mobile switching center (MSC). Receive an SMDPP response message and transmit an FSM Ack message to the gateway mobile switching center (GMSC).

The process of converting an FSM message into an SMDPP message is as follows. First, convert the value of the SM PR OA parameter included in the FSM message into the value of the OA parameter included in the SMDPP message, and convert the value of the SM RP DA parameter included in the FSM message into the value of the DA parameter included in the SMDPP message. Convert. Next, the value of the SM RP UI parameter included in the FSM message is converted into a value of a bearer data parameter included in the SMDPP message. At this time, the value of the SM RP UI parameter is the TPDU data of the FSM message, the parameter value of the bearer data (Bearerdata) is the bearer data of the SMDPP message.

The conversion of the value of the SM RP UI parameter included in the FSM message to the value of the bearer data parameter included in the SMDPP message may be performed through the following process. First, TP user data of TPDU data is converted into user data of the bearer data. Next, convert the TP Service Center Time Stamp of the TPDU data into the Message Center Time Stamp of the bearer data and the TP Originating Address of the TPDU data. Converts to a callback number of bearer data. Finally, the TP data coding scheme of the TPDU data is converted into a language indicator of the bearer data.

Changing the SRI (SendRoutingInfoSM) MAP data to SMSREQ MAP data is possible by changing the msisdn parameter value of the GSM SRI to the MIN parameter value. The parameters correspond to the parameters of msisdn, SM RP PRI, and serviceCentreAddress of GSM SRI, and MIN, ESN, SMS NI parameter of CDMA SMSREQ and are used for the same purpose.

When SMSREQ Ack MAP data is converted to SRI Ack MAP data, the sms Access Denied Reason, ESN and SMS Address values of CDMA SMSREQ Ack (SMSREQ) are changed to IMSI and msc Number values of GSM SRI Ack. In CDMA, the SMS address contains the location of the actual exchange, and the GSM identifies the location of the exchange with the value of IMSI. Matching matches SMS address and IMSI, but the information used uses unique value specified in the network. Also, other values are not conversions but additional values.

Similarly, replacing SMDPP MAP data with FSM (Forward SM) MAP data uses CDMA SMDPP's OA, DA, Bearer Data, TI, NI, MIN, SMS Charge Indicator, and SMS Message Count values.For GSM FSM, SM RP DA , SM RP OA, SM RP UI, More Message to Send The conversion converts the OA value of CDMA SMDPP to SM RP OA value of GSM, DA value to SM RP DA value, and bearer data to SM RP UI value. The rest of the values can be different for each operator.

The UMTS standard is also the 3GPP standard of WCDAM. CDMA is an IS-41.C / D standard. This standard is the standard of all systems linked by SS7 (Signaling System 7), and it is in charge of the interworking part of SMSC system and exchange, and the interworking part of SMSC and HLR. GSM is a GSM 09.20 specification. This document defines MAP data between all systems linked by SS7 used in GSM network. Similarly, the GSM 09.20 standard is a document that defines the GSM SMSC and GSM MSC / HLR interworking standard.

As shown in the figure, ISMSC decodes MAP data defined in IS-41.C / D and IS-637 standards and stores them in Short Message DB when SMS message is received from CDMA network. In the case of the subscriber, the CDMA message is encoded. In the case of the GSM subscriber, the GSM message is encoded. That is, the CDMA and GSM standards interworking with the SS7 interface can be simultaneously accommodated, and this type of network can provide SMS service to each other.
