Abstract

PURPOSE: A method for pushing data in a mobile system is provided to transmit a large amount of data to a terminal at a high speed using an IS-P5C's high-speed data service function. CONSTITUTION: A system confirms the capacity of a base station through an MSC(Mobile Switching Center)(21). A push server in the system acquires a subscriber list from the MSC. At this moment, the system, based on the subscriber list transmitted from the push server, calls a service user's terminal if the base station, in which the service user is located, is in an available state(22,23). The terminal, called from the system, confirms that the call is for push service, and executes an application in charge of push service(24). Accordingly, the traffic channel between the terminal and the base station is set up(25,26). The system transmits push data to the terminal(27). The terminal stores the received data after checking the integrity(28). Then the terminal informs the user that the push data have been received and stored(29).

Description

Data Pushing Method in Mobile Communication System {Method of Data Pushing in Mobile Phone}

The present invention relates to a data service method in a mobile communication system. In particular, a method of receiving data from a push server when a base station is idle in a IS-95C CDMA system using a service option 33 and pushing it to a terminal (MS). The present invention relates to a data push method in a mobile communication system that can efficiently transmit a large amount of information to a terminal (MS, user) using an idle base station (BTS) efficiently.

In general, SMS (Short Message Services) has been used to transmit / receive text messages.

In order to perform the SMS, the IS-637 protocol is performed and a short text message can be transmitted / received using Paging / Access / Traffic Channel.

More specifically, when describing the SMS, the terminal for the SMS should have an ICON that informs the status of the SMS message arrival on a specific key or menu that can access the SMS from the terminal structurally. Since SMS is one of the prominent supplementary services of CDMA, it has a separate access key. This key is used to display the menu of the SMS.

There is no difference in the H / W of the terminal and everything is implemented in S / W. Since SMS-related messages store messages in permanent storage memory, messages sent and received are related to their capacity because they require the use of an EEPROM (electrically erasable permanent memory device). In addition, the EEPROM may be slightly uncomfortable because the EEPROM is slower than other memory devices. For example, it takes some time to clear a message.

Characteristic of terminal S / W should be SMS processing routine added to existing S / W task and additionally interface with EEPROM, DM (Diagnostic Monitor) task. In order to support SMS, IS-637 must be implemented in the terminal, which consists of sending and receiving parameters with the existing S / W task. The SMS Task wakes up when the Service Option is 6 in the terminal Call Processing and performs the corresponding function.

The following is a general description of the conventional data service.

The data service using the service option 33 is a call setup for the terminal MS to access the internet network at high speed. That is, a high-speed data service of 144 Kbps establishes a call using service option 33.

On the other hand, the speed from the base station to the terminal is 144Kbps, and the speed from the terminal to the base station is 9.6Kbps.

In order to access the Internet using a high-speed data service, the terminal originates with a service option 33, and if the base station supports the service option 33, a base channel between the terminal and the base station is allocated by assigning a fundamental channel. Open and transmit / receive general data and control data (Signaling Message) through the channel.

Then, when there is more data to be sent from the base station to the terminal, the base station allocates a supplemental channel to the terminal and maintains the basic channel, and sends a message to the terminal to allocate the supplemental channel through the basic channel. Open to transmit data at high speed.

However, the above defined service option 33 is for connecting to the Internet at a high speed and cannot receive a terminal.

Therefore, in order to solve the above problems, the present invention proposes a high speed mass data push method in which a service provider or a content provider transmits a large amount of data at high speed to a terminal using the high speed data service function of the IS-95C.

The present invention includes the steps of identifying and calling a push service subscriber to provide a data push service; Establishing a call channel by checking whether the call is a push service; Transmitting push data to a terminal through the established channel; And storing and transmitting the transmitted push data to the user.

Other objects and features of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, a data pushing method in a mobile communication system according to the present invention will be described with reference to the accompanying drawings.

1 is a block diagram for a data push service of the present invention.

Looking at the configuration of the data push service of Figure 1, it consists of a system 10 and a mobile communication system 20, that is, a terminal.

The system 10 includes a content server 13, an exchange station 11 (MSC), and a push server 12 (PUSH SERVER) connecting the content server and the exchanger. The HLR 16, the VLR 15, and the base station controller 14 (BTS) are connected.

In addition, the base station 14 is connected to a mobile communication terminal, that is, a mobile station 20.

2 is a flowchart illustrating an embodiment of a data push method according to the configuration of FIG. 1.

As shown in the figure is a flow chart for data push between the system 10 and the terminal 20.

First, the capacity of the base station 14 is checked at the switching center 11 in the system. (Step 21). The HLR 16 then checks the subscriber information and location and sends it to the exchange 11 in a message. Thereafter, the push server 12 obtains subscriber information from the MSC 11, in which the system pushes the corresponding user (terminal) if the base station where the user who is to be provided with the service is available to the base station using the subscriber list from the push server. Call the terminal to know it (service option 33 and the specific phone number). (Steps 22, 23).

When the call is received from the system in step 23, the terminal 20 checks whether the push service is executed and prepares to receive the service by executing an application that is in charge of the push service. (Step 24).

Therefore, a communication channel is established between the terminal 20 and the base station 14 in the system. (Step 25, 26).

Thereafter, the system transmits the push data to the corresponding terminal, and the terminal receiving the data checks and stores the integrity of the received push data. (Step 27,28).

Therefore, the terminal informs the user that the push data is received / stored by using an alarm. (Step 29).

As described above, in the present invention, an idle base station (BTS) receives data from a push server when the base station is idle in the IS-95C CDMA system and receives data from the push server and pushes the data to the terminal MS. Efficiently use it to transmit a large amount of information to the terminal (MS, user) at high speed.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments.

Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

The present invention can transmit a large amount of information to a terminal (user) at a high speed by using an idle base station in a service provider such as a service provider, and the related content company can provide information necessary for the general public in addition to the existing method using the Internet or mail. Can provide.
