The present invention relates to a packet processing method and apparatus of a mobile communication service system. More particularly, when a voice call connection request message is received when a mobile station (MS) is in a dormant state for a packet service, The present invention relates to a packet processing method and apparatus for a mobile communication service system that minimizes a service providing time for providing an SVD service by simultaneously transmitting a packet to an MS and provides various multimedia additional services when establishing a voice call.

The mobile communication service technology provides a wireless communication service to a mobile station (MS) by building a packet transmission network in an existing mobile communication network. The packet network is composed of a Packet Data Service Node (PDSN) for setting an environment for providing a packet service, and a packet transmission network for transmitting a packet to an MS.

The packet transmission network can be divided into Universal Mobile Telecommunications System (UMTS) standardized by 3GPP, a European-based standardization organization, and CDMA2000 standardized by 3GPP2, a North American-based standardization organization.

A packet transmission network according to CDMA 2000 includes a PCF (Packet Control Function) and a PDSN, and is connected to a base station system (BSS) that exchanges code division multiple access (CDMA) signals with an MS.

The PCF manages the buffering of packets sent from the PDSN to wireless transmission, and manages the status of the MS. The PDSN provides the Network Access Server (NAS) function of establishing a Point-to-Point Protocol (PPP) session with the MS. Process. That is, the PDSN establishes, maintains, and terminates a PPP session for the terminal and a logical link for exchanging packets wirelessly, converts a packet transmitted from the MS into a packet, and transmits the packet to the IP network.

In a CDMA 2000 1X system, which is a general mobile communication service system, caller's telephone number information or character string information, which is voice reception information, is transmitted to a destination MS through an incoming signaling message.

The incoming MS displays phone number information and character string information included in the incoming signal message received together with the preset incoming information, or outputs through an audio transmitting device, but the incoming information to be transmitted to the destination MS is simple. Because it is limited to number information or character string information, there is a problem in that it cannot satisfy the needs of subscribers requesting various multimedia information as incoming information.

In addition, in the SVD (Simultaneously Voice & Data) service provided by the mobile communication service system, that is, a service that simultaneously provides a voice service and a packet service to the destination MS, a packet service is established after establishing a voice channel for a voice service in a wireless section. Since the traffic channel for providing is set, the channel setting time for providing the SVD service is greatly increased, and the quality of service is deteriorated.

That is, the time for setting up a channel for receiving a packet by the destination terminal from the service providing server that provides the packet in the SVD service is delayed, so that the destination MS accesses the service providing server and receives the packet to provide the SVD service to the subscriber. There is a problem with this delay.

Accordingly, the present invention has been made to solve the above problems, and in the mobile communication service system, a call connection request message for a voice service is received in a state in which a packet to be transmitted to a MS having a dormant state of a packet service of a mobile station exists. If the receiving MS receives the packet, or if the packet capacity is small, the step of re-establishing the packet service in the process of setting the voice channel for the voice service at the same time, the process of setting the voice channel An object of the present invention is to provide a packet processing method and apparatus of a mobile communication service system for transmitting a packet to a destination MS through a short data burst message (SDB).

Hereinafter, a method and apparatus for processing a packet in a mobile communication service system according to the present invention will be described in detail with reference to the accompanying drawings, and the description of the exchanged message and channel setting defines the specification of 'CDMA2000 1X radio interval standard and exchanger'. It is omitted since it is described in detail in the IOS literature.

1 is a block diagram illustrating a mobile communication service system according to a preferred embodiment of the present invention.

As shown in FIG. 1, a plurality of MSs 30 are connected to a Mobile Switching Center (MSC) 10 through each BSS 20, and the MSC 10 provides a service through a network. It is connected to a server 40 and a public switched telephone network (PSTN) exchange 50.

The service providing server 40 provides a push service (for example, a mail service, a messenger service, a news service, etc.) to each MS 30.

That is, if there is a packet for providing a push service to each MS 30 to the MSC 10, the service providing server 40 notifies that there is a packet to be transmitted to the MS 30 through the network. When the traffic channel is established through 30, the packet is transmitted to the MS 30 or the packet is provided to the MSC 10 so that the MSC 10 transmits the packet to the MS 30.

In this case, the network to which the MSC 10 and the service providing server 40 are connected may include a PDSN (not shown).

When the PSTN exchange 50 receives a call connection request signal for a voice service from a terminal connected to the PSTN, the PSTN switch 50 transmits a call connection request message to the MSC 10 or receives a call connection request message from the MSC 10. If so, the call connection request signal is transmitted to the terminal connected to the PSTN.

The MS 30 refers to a terminal for receiving a mobile communication service by a subscriber of the mobile communication service. When the call connection request message is received through the BSS 20, the MS 30 transmits a response message to set up a voice channel for the voice service. When the traffic channel setting for the packet service is requested, the traffic channel is set and the packets are exchanged.

In addition, the BSS 20 may include a base transformer system (BTS) and a base station controller (BSC), and the BTS is a base station wireless device that provides a wireless connection with the MS 30 and a wired / wireless connection function between the MS 30 and the BSC. In addition, the BSC is located between the BSS and the MSC 10 as a base station controller to process the management and control of the BSS 20.

The MSC 10 is a mobile communication switch for providing a mobile communication service to a subscriber of a mobile communication service, and processes such as circuit switching between subscribers, incoming / outgoing relay processing, hand-off, and roaming. do.

When the call connection request message is received through the PSTN exchange 50 or another MSC, the MSC 10 transmits the call connection request message to the corresponding MS 30 through the BSS 20.

When the response message is received from the MS 30, the MSC 10 checks whether the packet to be transmitted to the MS 10 exists in the service providing server 40, and if there is a packet, the call allocation request message. In the IOS standard, information indicating that there is a packet to be transmitted, that is, packet presence information, is added to the BSS 20.

In this case, the packet presence information transmitted by the MSC 10 through the BSS 20 may be transmitted in a Short Data Brust (SDB) form or a Short Massage Service (SMS) form, and the MSC 10 stores the packet. In this case, the MS 10 transmits the packet to the corresponding MS 10 in SDB form or SMS form, or transmits the unique information of the service providing server 40 providing the packet to the corresponding MS 10 so that the MS 10 provides the corresponding service. It is possible to receive a packet from the server 40.

That is, when the MSC 10 provides the SVD service, if there is a packet to be transmitted to the MS 30, the MSC 10 sets up a voice channel for providing a voice service while simultaneously setting up a traffic channel for providing a packet service. If the packet for the packet service is transmitted to the MS 30 or the capacity of the packet can be transmitted in the SDB form or the SMS form during the time spent in setting up the voice channel, the packet is transmitted in the SDB form while setting the voice channel. Alternatively, the SMS 30 is transmitted to the corresponding MS 30.

In the process of establishing a voice channel, a method of transmitting a packet to a corresponding MS 30 is to provide a SVD service by resetting a channel for a packet service as well as a voice service, and in this case, VP1 (Voice & Packet Service Type 1). It is preferable to set the channel according to the method.

This method transmits a packet using the FCH as a basic traffic channel because a call call for providing a voice service is established and used exclusively through a fundamental channel (FCH) to exchange packets before actual voice is transmitted. .

A method of transmitting a packet to the MS 30 in the form of SDB or SMS is a method of setting only V1 (Voice only Type 1, using FCH) and transmitting the packet through a signaling message according to DBM.

If the BSS 20 includes packet presence information in the allocation request message received from the MSC 10, the BSS 20 sets up a traffic channel with the MS 30 so that the packet provided from the service providing server 40 is transmitted to the MS 30. To be sent).

The BSS 20 transmits whether the multimedia information provided from the service providing server 40 is included in the MS 30 through an extended alert with information message.

2 is a flowchart illustrating a flow of a packet transmission method of a mobile communication system according to an embodiment of the present invention.

Referring to FIG. 2, if no traffic exchange occurs for a predetermined time through the traffic channel of the MS 30, the state of the traffic channel transitions to a dormant state (S 1).

In addition, when the MSC 10 receives a voice call connection request message to the MS 30 in a state where the traffic channel of the MS 30 transitions to a dormant state, the MSC 10 sends a paging request message to each BSS 20. The request message (Paging Request) is transmitted (S 2).

When the destination MS 30 is included in the serving cell, the BSS 20 transmits a GPM requesting voice channel establishment for voice service to the corresponding MS 30 when the paging request message is received (S 3).

When the GPM is received, the MS 30 transmits a page response message (Page Response), which is a response message, to the BSS 20 (S 4).

When the page response message is received, the BSS 20 transmits a paging response message, which is a response message of the paging request message, to the MSC 10 (S5).

When the paging response message is received from the BSS 20, the MSC 10 checks whether there is a packet to be transmitted to the MS 30 (S6), and if there is a packet, a call connection request message (Assignment Request). ) Is transmitted to the BSS 20 by including packet existence information (Multimedia Termination Info existed) indicating that the packet exists (S7).

In this case, the packet to be transmitted to the MS 30 by the MSC 10 is a packet for providing a push service, which is one of various types of multimedia data to be delivered by the service providing server 40 to the MS 30, according to an example. When the service providing server 40 needs to transmit a packet for providing a push service to the corresponding MS 30, the service providing server 40 notifies the MSC 10 that the packet exists, and the MSC 10 informs the packet presence information of the service providing server. The unique information of 40 is included and transmitted to the BSS 20.

3A is a diagram illustrating an allocation request message according to an embodiment of the present invention.

As shown in FIG. 3A, when there is a packet to be transmitted to the MS 30, the MSC 10 includes packet termination information in an information element of an assignment request message. Can be transmitted to the BSS 20.

The packet presence information added by the MSC 10 is determined by whether the service providing server 40 transmits the packet to the corresponding MS 30 through the network or the packet provided by the MSC 10 from the service providing server 40 in the form of SDB. Alternatively, packet transmission information indicating whether to transmit to the MS 30 in the form of SMS may be included.

3B is a diagram for explaining packet presence information according to an embodiment of the present invention.

As illustrated in FIG. 3B, the packet presence information included in the allocation request message includes element identifier information and packet transmission information (MTI value), which is information on a path through which a packet is received.

In this case, the packet transmission information may indicate whether the MS 10 receives a packet for providing a push service to the MS 30 from the service providing server 40 through the network, or the MSC 10 receives the packet in SDB or SMS form. Information about whether to transmit to the MS 30, and the BSS 20 simultaneously sets the traffic channel for the packet service and the MS 30 according to packet transmission information included in the call connection request message. Alternatively, the DBM including the received SDB or SMS may be transmitted to the MS 30.

3C is a diagram for explaining packet transmission information according to an embodiment of the present invention.

As shown in FIG. 3C, the MSC 10 may set packet transmission information differently according to a method of transmitting a packet to the MS 30.

According to an example, the MSC 10 temporarily stores the packet provided from the service providing server 40 and transmits the packet to the MS 30 in the SDB form or the SMS form during the process of setting up the voice channel for the voice service. If the packet transmission information is set to '0000 0000', the call connection request message is transmitted to the BSS 20, and the BSS 20 sets the packet transmission information of the received call connection request message to '0000 0000'. The DBM including the packet received in the SDB form or the SMS form is transmitted to the corresponding MS 30.

When the MS 30 receives a packet from the service providing server 40 through the network, the MSC 10 transmits a call connection request message to which the packet transmission information is set to '0000 0001' to the BSS 20. If the packet transmission information of the received call connection request message is set to '0000 0001', the BSS 20 also sets up a traffic channel for packet service with the MS 30 so that the MS 30 establishes a network. Through the service providing server 40 to receive a packet.

When the packet transmission information of the call connection assignment request message is set to '0000 0001', when the call connection request message is received from the MSC 10, the BSS 20 sends an extended channel assignment message (ECAM). And transmits the packet ID information (SCR = SR_ID: 1) and voice ID information (SCR = SR_ID: 6) in the service negotiation message (SCM), and transmits them to the MS 30 (S8). The voice channel is set (S 9).

In this case, the MSC 10 includes the unique information of the service providing server 40 providing the packet in the call connection request message, and the BSS 20 includes the unique information of the service providing server 40 included in the call connection request message. Is transmitted to the corresponding MS 30 so that the MS 30 can receive a packet from the corresponding service providing server 40 through the network.

When the MSC 10 transmits a packet to the MS 30 through the network, for example, the capacity of the packet to be transmitted from the service providing server 40 to the MS 30 is SDB. Alternatively, if it is too large to transmit in the form of SMS, the packet transmission information of the call connection request message is set to 0000 00001 and transmitted to the BSS 20.

At this time, the channel in which the MS 30 and the BSS 20 are configured through the service negotiation message may be VP1 (Physical fundicate channel: F / R-FCH only) or VP2 (Physical fundicate channel: F / R FCH + F / R -DCCH) can be used, and VP1 uses both F / R Forward / Reverse Fundamental Channel (FCH) for both voice packets and packet packets, and VP2 can be used according to service characteristics (quality requirements or user-specific classes). The MS 30 and the BSS 20 support a stable SVD service by using a dedicated control channel (DCCH) as a packet service and a basic channel (FCH) as a packet service.

Meanwhile, when the call connection request message is received from the MSC 10, the BSS 20 sets a voice channel for providing a voice service by including packet ID information and voice ID information in a universal handoff direction message (UHDM). In this case, the time for which a traffic channel is established can be minimized (S 10).

In addition, the service providing server 40 transmits a packet to the MS 30 when the traffic channel transitions to an active state or is set to the MS 30, and the BSS 20 receives a call to the MS 30. If there is multimedia information provided as signal information, an Extended Alert With Information Message including multimedia information is transmitted (S 11).

In this case, the MS 30 may receive a packet provided from the service providing server 40 in the form of an IP packet in the form of a PPP frame on a RLP (Radio Link Protocol).

In addition, when the packet service transitions to the active state in the process of setting up the voice channel through the service negotiation message, the destination MS 30 displays the multimedia information according to the packet provided from the service providing server 40 through the display means. Output through the voice output device.

4 is a flowchart illustrating a flow of a packet transmission method of a mobile communication system according to another exemplary embodiment of the present invention.

Referring to FIG. 4, when the traffic channel for the packet service set in the MS 30 transitions to a dormant state because no traffic exchange occurs for a predetermined time (S 20), the MSC 10 receives a call connection request message. When received, a Paging Request message, which is a call connection request message, is transmitted to each BSS 20 (S 21), and each BSS 20 receives a paging request message to a corresponding MS 30 when a paging request message is received. The GPM requesting the setting is transmitted (S 22).

When the GPM is received, the MS 30 transmits a page response message (Page Response), which is a response message, to the BSS 20 (S 23), and when the page response message is received, the BSS 20 receives a paging request message. A paging response message (paging response), which is a response message, is transmitted to the MSC 10 (S 24).

When the paging response message is received from the BSS 20, the MSC 10 checks whether a packet to be transmitted to the MS 30 exists. If the packet exists, the MSC 10 has a capacity of one or more SDBs. Or it is determined whether the transmission to the MS in the form of SMS (S 25).

In this case, the service providing server 40 transmits the packet to the MSC 10 if the capacity of the packet for providing the push service to the MS 30 is a capacity that can be included in one or a plurality of SDBs or SMSs.

When the MSC 10 determines that the packet can be transmitted in the SDB or SMS form, the MSC 10 includes a packet termination information (Multimedia Termination Info existed) indicating that the packet exists in the call request request message (BSS). 20) (S 26).

When the BSS 20 receives an allocation request message from the MSC 10, the BSS 20 transmits a channel assignment message (ECAM) to the corresponding MS 30 so that a voice channel for voice service is established (S 27).

In addition, the MSC 10 generates an SDB or SMS including a packet to be transmitted to the MS 30, and BSS a packet delivery message (ADD Delivery Request) for transmitting the generated SDB or SMS to the MS 30. Transmit to 20 (S 28).

According to an example, when the MSC stores the packet provided from the service providing server 40, the MSC transmits a call connection request message with the packet transmission information set to '0000 0000' to the BSS 20, and the BSS 20. If the packet transmission information of the received call connection request message is set to '0000 0000', it recognizes that there is a packet transmitted in the SDB form or the SMS form, and is included in the SDB form or the SMS form of the received packet transfer message. The packet is transmitted to the corresponding MS 30 through the DBM (S 29).

In this case, the SDB or SMS for transmitting the packet to the corresponding MS 30 may be generated in the MSC 10 or the PCF (not shown).

The BSS 20 includes the voice ID information in the service negotiation message (SCM) and transmits it, so that the voice channel for the voice service can be set (S30).

If there is multimedia information to be provided as the incoming signal information, the BSS 20 transmits an extended alert message including the multimedia information (S 31).

5 is a flowchart illustrating a packet transmission method of a mobile communication system according to an embodiment of the present invention.

Referring to FIG. 5, if the traffic channel for packet service does not exchange traffic for a predetermined time, the MS 30 of the mobile communication service system transitions to a dormant state (S 100).

When the service providing server 40 providing the push service to each MS 30 of the mobile communication service system needs to transmit a packet for providing a push service to each MS 30 to the corresponding MS 30, Send the packet to the MSC 10, or inform the MSC 10 that there is a packet to send.

When the call connection request message is received, the MSC 10 checks whether there is a packet to send to the destination MS 30, and determines whether to send the packet in the form of SDB or SMS (S 110).

That is, when the MSC 10 receives an SVD service request, for example, when there is a voice service request with the packet service set to the dormant state, the MSC 10 establishes a voice channel for providing a voice service. While setting, it is checked whether there is a packet to be transmitted to the MS 30, and if there is a packet, whether to transmit the packet to the MS 30 in SDB or SMS form or setting a traffic channel, It is determined whether or not to allow 30 to receive a packet from the service providing server 40 through the network.

In addition, when the MSC 10 temporarily stores the packet provided from the service providing server 40, the MSC 10 transmits the packet to the corresponding MS 30 in the form of SDB or SMS, and has a packet to be transmitted to the MS 30. When received from the service providing server 40, the MS 30 establishes a traffic channel so that the MS 30 can receive a packet from the service providing server 40 via the network.

When the MSC 10 determines that the packet should be transmitted to the MS 30 in the SDB form or the SMS form, the MSC 10 transmits a call connection request message including the packet presence information to the BSS 20 and includes the packet. SDB or SMS is generated and transmitted to the BSS 20 (S 120).

At this time, the SDB or SMS may be generated in the MSC 10 or PCF (not shown).

When the BSS 20 receives a call connection request message including packet presence information received from the MSC 10, the BSS 20 transmits a channel assignment message for establishing a voice channel to the corresponding MS 30, and receives the received SDB or SMS. The DBM is transmitted to the corresponding MS 30 (S 130).

After the BSS 20 transmits the service negotiation message for establishing the voice channel to the corresponding MS 30, the BSS 20 transmits an incoming signal message including the multimedia information to the MS 30 (S 140).

The MS 30 displays the display information according to the multimedia information included in the packet or the incoming signal message received through the DBM or outputs the voice information (S 180).

Meanwhile, when the MS 30 needs to receive a packet from the service providing server 40 through the network, the MSC 10 transmits an allocation request message including the packet presence information to the BSS 20 (S 150). .

In this case, the packet presence information included in the allocation request message by the MSC 10 may include unique information of the service providing server 40 providing the packet, and the unique information may be provided by the corresponding MS 30 through a network. This may correspond to address information for receiving a packet by accessing the server 40.

If the packet allocation information is included in the received allocation request message, the BSS 20 sets the voice channel for providing the voice service by including the voice ID information and the packet ID information in the service negotiation message for establishing the channel. In step S160, the MS 30 may receive a packet provided by the service providing server 40 through the traffic channel.

In addition, the BSS 20 transmits an Extended Alerting With Information Message including multimedia information to the corresponding MS 30.

The MS 30 sets the voice channel according to the voice ID information included in the service negotiation message and sets up the traffic channel according to the packet ID information.

When the traffic channel is established, the MS 30 uses the unique information of the service providing server 40 to access the service providing server 40 through a network, and receives the packet provided from the service providing server 40. Receive (S 170).

Then, the MS 30 outputs the display information or the voice information according to the packet provided from the multimedia information or the service providing server 40 included in the received incoming signal message (S 180).

In the detailed description of the present invention, when the packet service state of the MS for providing the packet service is in the dormant state, the voice service request is described. However, the same is true when the packet service state is in the active state or the null state. It can be seen that it applies.
