The present invention relates to a packet data service system, and more particularly, to dynamically adjust a dormant timer applied to a system according to the type of content required by a mobile terminal to improve system resources and operation efficiency. It relates to a packet data service method.

With the development of computer and communication technology, various wireless communication services are provided using a wireless communication network. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while supplementing the voice call service by providing a text message service, recently, a wireless Internet service that provides an Internet communication service through a wireless communication network to a user of a mobile terminal has emerged.

As part of the wireless Internet service, in recent years, a packet data service system for converting various multimedia contents including video into packet data using a mobile communication system and providing them to a mobile terminal has been developed to satisfy various needs of mobile subscribers. Efforts to meet are ongoing.

The packet data service system described above includes three states, namely, active / connected state, dormant state, and idle state, for efficient data communication in packet communication between the mobile terminal and the system. It has a null / inactive state.

In the active / connected state, a physical traffic channel for packet data transmission between a mobile station and a base station system is formed, and a point-to-point protocol between the mobile terminal and a packet data service node (PDSN) is provided. ; PPP) maintains the link.

The dormant state refers to a state in which no physical traffic channel exists between the mobile station and the base station system, and a PPP link is maintained between the mobile station and the PDSN.

The idle / inactive state refers to an idle state in which no physical traffic channel exists between the mobile station and the base station system, and at the same time, there is no PPP link between the mobile station and the PDSN.

On the other hand, if the mobile terminal does not use the data for a certain time in the active / connected state of the system, the system is switched to the doping state, at this time, a dormant timer (Dormant Timer) for a certain time that does not use the data continuously It is referred to as.

In general, the dome timer is managed by the system and the mobile terminal uniformly without considering the type of service. Therefore, when the dormant timer is large, the physical traffic channel formed between the mobile terminal and the system is maintained for a long time, thereby reducing the system resource efficiency for packet data transmission. On the other hand, if the dormant timer is too small, the transition to the dormant state of the system becomes frequent, which lowers the system operating efficiency.

Therefore, when the conventional packet data service system downloads content once and terminates the service, the above-mentioned conventional dormant timer does not act as a deterrent to system operation. However, when a conventional packet data service system repeatedly downloads content of a relatively small size, such as a newspaper, and checks the content while maintaining a connection, the packet data service system is managed uniformly regardless of the type of content. Existing dormant timers hinder system resources and operational efficiency.

The present invention was created to solve the problems inherent in the prior art as described above, and an object of the present invention is to dynamically change a Dormant Timer on a system according to the type of content required by the mobile terminal. The present invention provides a packet data service method to be adjusted and applied.

In order to achieve the above object, in accordance with an aspect of the present invention, there is provided a packet data service method comprising: a packet data service node (PDSN) in a packet data service network, the packet data of any mobile terminal from a base station system; A destination address (IP) is provided according to the service request, and a dormant timer according to the type of content provided from the content providing server corresponding to the destination address is applied.

In the above configuration, the packet data service node stores an address of a plurality of content providing servers that provide the packet data service and types of content provided by the respective content providing servers, and is optimized according to the content type. Mapping timer.

According to yet another aspect of the present invention, there is provided a packet data service method comprising: a) a mobile terminal requesting a base station system to transmit packet data of specific content; b) the base station system receiving a packet data request of the mobile station to determine a destination address (IP) for call processing; And c) a packet data service node (PDSN) receiving the destination address from the base station system and applying a Dormant Timer according to the type of content provided at the destination address.

In the above configuration, step c) includes: c-1) receiving the destination address from a base station system; c-2) identifying a content providing server corresponding to the destination address, and identifying a type of content provided by the identified content providing server; c-3) extracting a dormant timer suitable for the identified content type based on the mapped information; And c-4) applying the extracted dormant timer to a system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic structural diagram of a packet data service system according to an embodiment of the present invention.

As shown in FIG. 1, the system includes a mobile terminal 100, a base station 200, a base station controller 300, a switch 400, a PCF 500, a packet data service node (PDSN, 600); And IP router 700; has a configuration including.

The base station 200 provides a radio interface function with the mobile terminal 100.

The base station controller 300 matches with the base station 200, matches with the switch 400, and performs resource allocation, call control, handoff control, power saving control, voice and packet processing, and the like.

The switch 400 matches the base station controller 300 to perform voice call switch control, call processing, billing / authentication / subscriber information processing, and the like.

The PDSN 600 is responsible for an interface between packet data transmission on a fixed network, packet data transmission on a wireless network, and packet data transmission on a wireless network, and the switch 400 through the PCF 500. Interface with. In addition, the PDSN 600 stores the addresses of the plurality of content providing servers 800_1 to 800_n that provide packet data services and the types of contents provided by the respective content providing servers, and stores the stored information and the respective information. The dome timer optimized according to the content type provided by the content providing servers 800_1 to 800_n includes a mapping table mapped.

The IP router 700 plays a role of providing a path for an interface with a corresponding content providing server 700_1 to 700_n according to a system and a destination address.

Through such a configuration, the PDSN 600 receives a destination address (IP) according to a packet data service request of the mobile terminal 100 from the switch 400 through the PCF 500, and receives the destination address. A dormant timer optimized according to the type of content provided from the content providing servers 800_1 to 800_n corresponding to the application is applied to the system.

Hereinafter, a packet data service method according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. 2 and 3 are flowcharts illustrating a packet data service method according to an embodiment of the present invention.

First, the mobile terminal 100 requests packet data transmission of specific content to a base station system including the base station 200, the base station controller 300, the exchange 400, and the PCF 500 (S100).

Subsequently, the base station system receiving the packet data transmission request from the mobile terminal 100 determines a destination address (IP) for any content providing server 800_1 to 800_n to which the mobile terminal 100 is to access. The packet data call is set (S200). That is, the exchange 400 receives the packet data transmission request transmitted from the mobile terminal 100, grasps the destination address included in the packet data transmission request, and based on the determined destination address, the PCF 500. And a packet data call with the corresponding content providing servers 800_1 to 800_n through the PDSN 600.

At the same time, the PDSN 600 receives the destination address provided from the exchange 400 through the PCF 500 to identify specific content providing servers 800_1 to 800_n according to the destination address. A dome timer suitable for the content type provided by the content providing servers 800_1 to 800_n is extracted and applied to the system (S300). That is, as shown in FIG. 3, the PDSN 600 receives the destination address from the PCF 500 (S310), and checks the content providing servers 800_1 to 800_n corresponding to the destination address (S320). . Thereafter, the PDSN 600 identifies the type of content provided from the identified content providing server (S330), extracts a dormant timer optimized for the identified content type through the mapping table (S340), and extracts the extracted content timer. The dome timer is applied to the system (S350).

As described above, the PDSN 600 according to the present invention, for example, the mobile terminal 100 is connected to a specific content providing server (800_1 ~ 800_n), download the content of a relatively small size, such as newspaper, and access In the case of repeatedly performing the process of checking the corresponding content while maintaining the state, by applying a dormant timer having a long time (first time) to the system, the system is activated / connected until the user is provided with all the corresponding contents. Maintain state. On the other hand, when the mobile terminal 100 connects to a specific content providing server 800_1 to 800_n, downloads the content one time and terminates the service, the mobile terminal 100 has less time (second time) than the long time (first time). A dormant timer is applied to the system, bringing the system to the dormant state at about the same time as the content delivery completion time.

As can be seen from the above, the packet data service method according to the present invention includes a dormant timer optimized according to the type of content and the type of content provided from a specific content providing server to a packet data service node (PDSN).
