METHOD AND SYSTEM OF PROVIDING PACKET DATA SERVICE TO TERMINAL EQUIPMENT IN DORMANT STATE

Technical Field

[1] The present invention relates to a packet network, and more particularly, to a method and system for waking up a terminal equipment in a dormant state and providing a packet data service to the terminal equipment. Background Art

[2] A content providing server links up with a various types of mobile communication networks to form a packet network through which a packet data service can be provided to terminal equipments in the communication networks.

[3] Generally, a mobile communication network includes a medium access control

(MAC) layer, which dynamically allocates or cancels a communication channel between a base station and a terminal equipment, in order to transmit packet data efficiently.

[4] The terminal equipment and the base station, which are controlled by the MAC layer, maintain one of the following states in common. An active state is a state in which a packet data service is provided. A dormant state is a state in which an Internet Protocol (IP) address is allocated, but data traffic does not exist, and thus a communication channel is canceled. Besides, there are a control hold state in which only a control channel is maintained and a communication channel is ready to be allocated at a data transmission request, a suspended state in which even the control channel is canceled but link to the base station is maintained, and a null state in which even an IP address is not allocated.

[5] Usually, in order to provide a packet data service to a terminal equipment in the dormant state, a content providing server sends a short message, which includes a wake-up request and an address of the content providing server, to the terminal equipment using a short message service (SMS). "Wake-up" indicates the conversion of the terminal equipment transits from the dormant state to the active state. After recognizing the short message, the terminal equipment accesses the content providing server and receives the packet data service.

[6] Such a method of providing a packet data service to a terminal equipment in the dormant state includes many processes before the service is finally provided.

[7] Moreover, a content providing server can provide a packet data service to a terminal equipment using a push service but cannot perform the push service with respect to a terminal equipment in the dormant state. Accordingly, a real-time service cannot be ensured.

[8] In addition, because of the nature of the SMS, if a terminal equipment in the dormant state does not recognize a message within a predetermined period of time, a reliability problem like loss of the message may occur. Moreover, service providers which do not have SMS infrastructure need to construct the SMS infrastructure in order to provide a packet data service to a terminal equipment in the dormant state. Disclosure of Invention Technical Solution

[9] The present invention provides a packet data service providing method for waking up a terminal equipment in a dormant state through signaling in a mobile communication network based on location information of the terminal equipment and transmitting packet data to the terminal equipment in real time instead of connecting the terminal equipment to a content providing server using a short message service (SMS), and a recording medium for recording a computer program for executing the method.

[10] The present invention also provides a system for executing the packet data service providing method.

Advantageous Effects

[11] According to the present invention, in order to provide a packet data service to a terminal equipment in a dormant state, instead of requesting the terminal equipment to access a content providing server using a short message service (SMS), the terminal equipment is directly waken up through signaling in a mobile communication network based on location information of the terminal equipment and the packet data service is provided to the terminal equipment. Accordingly, a push service can be provided in real time even to the terminal equipment in the dormant state and the packet data service can be provided with simpler procedure and improved reliability.

[18] According to an aspect of the present invention, there is provided a method of waking up a terminal equipment in a dormant state and providing a packet data service to the terminal equipment. The method includes requesting to provide the packet data service to the terminal equipment in the dormant state in a predetermined mobile communication network using a predetermined content providing server; requesting and acquiring location information of the terminal equipment in the dormant state based on the request for the packet data transmission; sending a page request to the terminal equipment in the dormant state based on the location information; creating a session between the content providing server and the terminal equipment according to a response to the paging request; and transmitting packet data to the terminal equipment.

[19] According to another aspect of the present invention, there is provided a termination control system for providing a packet data service to a terminal equipment in a dormant state in a mobile communication network. The termination control system includes a location information manager, a paging request unit, and a packet transmitter. The location information manager manages location information of the terminal equipment. The paging request unit requests a base station covering the terminal equipment in the dormant state to page the terminal equipment based on the location information of the terminal equipment when receiving from a predetermined content providing server a request to transmit packet data to the terminal equipment in the dormant state in the mobile communication network so as to page the terminal equipment. The packet transmitter transmits the packet data through a session created for the paged terminal equipment. Mode for the Invention

[20] Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention with reference to the attached drawings, in which like reference numerals refer to like elements throughout.

[21] FIG. 1 illustrates a packet network 100 for providing a packet data service to a terminal equipment (user equipment) 120 in a dormant state in a wide-band code division multiple access (W-CDMA) network 110, according to some embodiments of the present invention. [22] In the current embodiments, a packet data service is provided based on a session initiation protocol (SIP). The SIP is a text-based application-layer control signaling protocol describing procedures for creating, modifying, and terminating sessions. The SIP is completely independent of a network transfer protocol and media and defines the procedure regardless of a type of content and thus has a simple structure and is highly scalable. For this reason, many systems use the SIP recently.

[23] The packet network 100 includes the W-CDMA network 110, an user equipment

(UE) 120 in a dormant state, an Internet protocol (IP) multimedia core network subsystem (IMS) 130 for providing a multimedia service based on an IP, a termination control system (TCS) 140, and a home location register (HLR) 150.

[24] The W-CDMA network 110 includes a gateway general packet radio service

(GPRS) support node (GGSN) 111 functioning as a gateway between the W-CDMA network 110 and the packet network 100, a serving GPRS supporting node (SGSN) 112 processing packet data, and a radio network controller (RNC) 113 controlling a base station.

[25] The IMS 130 uses the SIP as a signaling protocol for setting multimedia connection. The IMS 130 includes a call session control function (CSCF) unit 132 essential to processing a SIP message and an application server (AS) 131 which is a service platform providing a content service to the UE 120 through SIP interface with the CSCF unit 132.

[26] The HLR 150 is a mobile communication subscriber database including terminal information, registered information and location information of a mobile communication subscriber and having an authentication function.

[27] FIG. 2 is a block diagram of the TCS 140.

[28] Referring to FIG. 2, the TCS 140 includes an SIP interface unit 141, a location information manager 142, a paging request unit 143, a packet data transmitter 144, and a controller 145.

[29] The SIP interface unit 141 processes a SIP message.

[30] The location information manager 142 manages location information of UEs. When a message requesting a packet data service is transmitted from the AS 131 to the UE 120 in the dormant state, if the location information manager 142 does not have location information of the UE 120, it requests and acquires the location information of the UE 120 from the HLR 150.

[31] The paging request unit 143 transmits a paging request message to the UE 120 through signaling in the W-CDMA network 110, based on the location information of the UE 120.

[32] When a session is created between the UE 120 and the TCS 140 in response to the paging request message, the packet data transmitter 144 transmits packet data using a push service.

[33] The controller 145 controls the TCS 140 as a whole.

[34] The push service uses push technology of automatically transmitting data to a UE even when the UE does not request a service. [35] FIG. 3 is a flowchart of a method of providing a packet data service to the UE 120 in the dormant state in the W-CDMA network 110, according to some embodiments of the present invention. [36] Referring to FIGS. 1 and 3, the method of providing a packet data service from the

AS 131 to the UE 120 in the dormant state is performed as follows. [37] In operations S301 and S302, the AS 131 transmits a SIP message INVITE, which requests to provide a packet data service to the UE 120 in the dormant state, to the TCS

140 via the CSCF unit 132. [38] In operation S303, the TCS 140 requests location information of the UE 120 from the HLR 150 using a mobile application protocol (MAP) message SendRoutingln- foForGprs, based on the SIP message INVITE. [39] In operation S304, the TCS 140 acquires the location information of the UE 120, that is, an address of the SGSN 112 including the UE 120. [40] In operation S305, the TCS 140 transmits a protocol data unit (PDU) notification request message to the address of the SGSN 112 to request paging. [41] In operation S306, in response to the paging request, the SGSN 112 transmits a packet data protocol (PDP) context activation request message to the UE 120 to request paging. Thereafter, in operation S307, the SGSN 112 transmits a PDU notification response message to the TCS 140 to respond to the paging request. [42] In operation S308, in response to the paging request, the UE 120 transmits an active

PDP context request message to the SGSN 112. In operation S309, the SGSN 112 and the GGSN 111 transmit and receive a create PDP context activation message. As a result, paging is completed and an IP bearer path is secured between the UE 120 and the GGSN 111. [43] The paging is a process of calling a UE in a mobile communication network through a base station controller in a coverage including the location of the UE when the UE has an incoming call.

[44] The IP bearer path is a path through which a packet is transmitted based on an IP.

[45] When the IP bearer path is secured in operation S308, the GGSN 111 informs an

ACR message to the IP address of the UE 120 by the TCS 140 in operation S310. In response to the ACR message, the TCS 140 transmits an ACA message to the GGSN

111 in operation S311. [46] Through operations S303 through S311, an IP connection between the TCS 140 and the UE 120 is created. [47] Thereafter, an IMS call flow is performed as follows.

[48] In operation S312, the UE 120 transmits a SIP message REGISTER to the CSCF unit 132. In operation S313, the CSCF unit 132 transmits the SIP message REGISTER to the TCS 140. Through operations S312 and S313, the UE 120 is registered in the TCS 140.

[49] In operation S314, the TCS 140 transmits a SIP message INVITE to the UE 120 to request a session.

[50] Thereafter, when the TCS 140 receives a response to the session request from the

UE 120, a session is created between the UE 120 and the TCS 140, and the TCS 140 transmits packet data to the UE 120 using a push service in operation S315.

[51] The above-described embodiments relate to a packet network for transmitting packet data to the UE 120 in the dormant state using the push service based on the SIP in the W-CDMA network 110. In other embodiments of the present invention, the push service may be provided based on a wireless application protocol (WAP). The present invention is not restricted to the above-described embodiments. When the packet network is not based on the SIP, the SIP interface unit 141 included in the TCS 140 is replaced with a call processing interface unit which processes a message according to a current protocol instead of a SIP message.

[52] FIG. 4 illustrates a packet network 400 for providing a packet data service to a UE

420 in a dormant state in a wireless broadband (WiBro) Internet 410, according to other embodiments of the present invention.

[53] WiBro enables a various types of mobile Internet terminal equipments to access wireless Internet at high speed at any time and any place regardless of whether the terminal equipments are stationary or moving and is an IP-based wireless data system having a characteristic of asymmetric download/upload allocation.

[54] In the current embodiments of the present invention, a packet data service is provided based on the SIP.

[55] The packet network 400 includes the WiBro Internet 410, the UE 420 in a dormant state, an IMS 430 for providing a multimedia service based on an IP, a TCS 440, and a location management server (LMS) 450.

[56] The WiBro Internet 410 includes an access control router (ACR) 411, which is a

WiBro control office performing subscriber s session management, IP allocation, authentication, billing, and user traffic processing; and a radio access station (RAS) 412, which is a WiBro base station performing communication with the UE 420 through a medium access control (MAC) layer.

[57] The IMS 430 uses the SIP as a signaling protocol for setting multimedia connection. The IMS 430 includes a CSCF unit 432 essential to processing a SIP message and an AS 431 which is a service platform providing a content service to the UE 420 through SIP interface with the CSCF unit 432. [58] The TCS 440 includes an SIP interface unit 441, a location information manager

442, a paging request unit 443, and a packet data transmitter 444. [59] When receiving an SIP message, which requests to provide a packet data service to the UE 420 in the dormant state in the WiBro Internet 410, from the AS 431 via the

SIP interface unit 441, the TCS 440 transmits a message requesting to page the UE 420 to the LMS 450 via the paging request unit 442 based on the location information of the UE 420 obtained from the location information manager 442. The TCS 440 suspends packet data and, when a session is created between the UE 420 and the TCS

440, transmits the packet data to the UE 420 via the packet transmitter 443 using a push service. [60] The LMS 450 is a server, which manages location and session information of the

UE 420 in the WiBro Internet 410 through the interface with the ACR 411, and also serves to request to page the UE 420 based on the location information of the UE 420. [61] FIG. 5 is a block diagram of the TCS 440.

[62] Referring to FIG. 5, the TCS 440 includes the SIP interface unit 441, the location information manager 442, the paging request unit 443, the packet data transmitter 444, and a controller 445. [63] The SIP interface unit 441 processes a SIP message. The location information manager 442 manages location information of UEs. [64] The paging request unit 443 transmits a paging request message to the UE 420 through signaling in the WiBro Internet 410, based on the location information of the

UE 420. [65] When a session is created between the UE 420 and the TCS 440 in response to the paging request message, the packet data transmitter 444 transmits packet data using the push service.

[66] The controller 445 controls the TCS 440 as a whole.

[67] FIG. 6 is a flowchart of a method of providing a packet data service to the UE 420 in the dormant state in the WiBro Internet 410, according to other embodiments of the present invention. [68] Referring to FIGS. 4 and 6, the method of providing a packet data service from the

AS 431 to the UE 420 in the dormant state is performed as follows. [69] In operations S601 and S602, the AS 431 transmits a SIP message INVITE, which requests to provide a packet data service to the UE 420 in the dormant state, to the TCS

440 via the CSCF unit 432. [70] In operation S603, the TCS 440 transmits an AL-PAGE-REQ message requesting to page the UE 420 to the LMS 450 based on the SIP message INVITE. [71] In operation S604, the LMS 450 transmits an AL-TRIG-REQ message requesting paging to the ACR 411 based on the AL-PAGE-REQ message.

[72] In operation 605, the ACR 411 performs a paging function with the UE 420 using an A-PAGE message transmitted via the RAS 412 based on the AL-TRIG-REQ message, so that an IP bearer path is secured between the ACR 411 and the UE 420.

[73] After the IP bearer path is secured in operation S605, the ACR 411 transmits an

AL-LOC-UPDATE message to the LMS 450 in response to the paging request in operation S606 and the LMS 450 transmits an AL-PAGE RES message to the TCS 440 in operation S 607.

[74] Thereafter, an IMS call flow is performed as follows.

[75] In operation S608, the UE 420 transmits a SIP message REGISTER to the CSCF unit 432. In operation S609, the CSCF unit 432 transmits the SIP message REGISTER to the TCS 440. Through operations S608 and S609, the UE 420 is registered in the TCS 440.

[76] After the registration, the TCS 440 transmits a SIP message INVITE to the UE 420 to request a session in operation S610.

[77] Thereafter, when the TCS 440 receives a response to the session request from the

UE 420, a session is created between the UE 420 and the TCS 440, and the TCS 440 transmits packet data to the UE 420 using the push service in operation S611.

[78] The above-described embodiments relate to a packet network for transmitting packet data to the UE 420 in the dormant state using the push service based on the SIP in the WiB ro Internet 410. In other embodiments of the present invention, the push service may be provided based on a WAP. The present invention is not restricted to the above-described embodiments. When the packet network is not based on the SIP, the SIP interface unit 441 included in the TCS 440 is replaced with a call processing interface unit which processes a message according to a current protocol instead of a SIP message.

[79] While the present invention has been shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and detail may be made herein without departing from the spirit and scope of the present invention, as defined by the following claims. Industrial Applicability

[80] According to the present invention, in order to provide a packet data service to a terminal equipment in a dormant state, instead of requesting the terminal equipment to access a content providing server using a short message service (SMS), the terminal equipment is directly waken up through signaling in a mobile communication network based on location information of the terminal equipment and the packet data service is provided to the terminal equipment. Accordingly, a push service can be provided in real time even to the terminal equipment in the dormant state and the packet data service can be provided with simpler procedure and improved reliability.
