Also, the scenarios and the messages are defined according to the service provided by the service provider.

Therefore, there has been a demand for technical means and methods for subscribers to receive data services by subscribing to PPS in the IMT-2000 network.

Accordingly, the present invention has been made in view of the above-described needs, and an object of the present invention is to exist in the 3GPP standard through interworking between a Serving GPRS Support Node (SGSN) and an SCP (Service Control Point) of an IMT-2000 asynchronous network. The present invention provides a method for providing PPS in a mobile communication network suitable for selecting a message to be written and a scenario.

In order to achieve the above object, the present invention provides a method for providing a prepayment service in a mobile communication network through the interworking of the SGSN and SCP, the first step of activating / deactivating a data service within a certain usage limit; A second step of activating the data service up to a usage limit; A third step of moving the SGSN while activating a data service within a usage limit; Updating a routing area; A fifth step of moving the SGSN without using the data service; And a sixth process of moving a routing area without using a data service.

(Serving GPRS Support Node) 106, Gateway GPRS Support Node (GGSN) 108, and Service Control Point (SCP) 110.

As shown, the MS 100 is a terminal, that is, an asynchronous terminal in this embodiment, and the subscriber can use the MS 100 to wirelessly connect to the network.

Node B 102 is an asynchronous base station that arbitrates between the MS 100 and the RNC 102, enabling wireless communication with the MS 100 to exchange messages with each other. Although only one node B 102 is shown for convenience of description, it will be readily apparent to those skilled in the art that a plurality of Node Bs 102 may be connected in one RNC 104.

RNC 104 is an asynchronous base station controller, which refers to an automated system that interfaces user communications over a wireless network.

SGSN 106 and GGSN 108 are asynchronous IMT-2000 data service nodes and service gateway nodes, and SGSN 106 exchanges data service related information, subscriber information, etc. in cooperation with SCP 110, which will be described later. That is, when the SGSN 106 registers in the packet network at the MS 100, it extracts subscriber information from a Home Location Register (HLR) (not shown) and generates data service related information through a subscriber authentication process. do. That is, in order to receive data service from the MS 100, data activation is required. In this case, data service related information (eg, an IP address) is generated in the GGSN 108 and the SGSN 106, and the subscriber is a PPS service subscriber. SGSN 106 transmits subscriber information to SCP 110 in conjunction with SCP 110. In addition, SGSN 106 also performs a function of reporting to SCP 110 when a certain amount of use and a predetermined time.

SCP 110 refers to a service controller, and requests SGSN 106 to report data usage and usage time based on subscriber information. In addition, SCP 110 performs a function of controlling the PPS service through real-time charging based on usage and usage time.

First, if MS 100 requests data service activation from SGSN 106 (1), SGSN 106 requests radio resource allocation to UTRAN (2).

SGSN 106 requests GGSN 108 to generate information for data service activation, and GGSN 106 responds (3).

SGSN 106 verifies subscriber information and informs SCP 110 that the PDP context has been activated (4), and SCP 110 causes SGSN 106 to report upon PDP context disconnection and location change. (5).

In addition, SCP 110 requests the SGSN 106 to report when a certain amount of time expires (6), and requires the SGSN 106 to continue processing (7).

At this time, SGSN 106 grants data service activation to MS 100. Thus, the user can receive data service (8).

Next, SGSN 106 monitors usage time and usage, and reports the fact to SCP 110 when SCP 110 requests a certain amount of time and amount required (9).

In addition, SCP 110 requests to report when SGSN 106 expires for a certain amount of time (10).

Thereafter, if the user requests data service deactivation (11), SGSN 106 reports to SCP 110 that a PDP context release event has occurred (12).

In addition, SGSN 106 reports to SCP 110 the last usage time and usage amount used by the user (13).

The SGSN 106 then requests the GGSN 108 to delete the PDP context, and the SGSN 106 responds 14.

Accordingly, the SGSN 106 allows data service deactivation to the MS 100 (15) and releases radio network resources (16).

3 is a timing chart of a data service activation process when a subscriber has used up a certain usage limit as a prepayment service process in a mobile communication network according to another embodiment of the present invention.

SGSN 106 requests GGSN 108 to generate information for data service activation, and GGSN 106 responds (3).

SGSN 106 verifies subscriber information and informs SCP 110 that the PDP context has been activated (4), and SCP 110 causes SGSN 106 to report upon PDP context disconnection and location change. (5).

In addition, SCP 110 requests the SGSN 106 to report when a certain amount of time expires (6), and requires the SGSN 106 to continue processing (7).

At this time, SGSN 106 grants data service activation to MS 100. Thus, the user can receive data service (8).

Next, SGSN 106 monitors usage time and usage, and reports the fact to SCP 110 when SCP 110 requests a certain amount of time and amount required (9).

In addition, SCP 110 requests to report when SGSN 106 expires for a certain amount of time (10).

In addition, the SGSN 106 monitors usage time and usage, and reports to SCP 110 when the predetermined time and amount required by SCP 110 expire (11).

If the user has used up all the subscribed amounts, SCP 110 requests SGSN 106 to delete the PDP context (12).                     

The SGSN 106 then requests the GGSN 108 to delete the PDP context, and the GGSN 108 responds to the SGSN 106 (13).

Accordingly, SGSN 106 requests data service deactivation to MS 100 (14), and MS 100 accepts data service deactivation to SGSN 106 (15).
