Description

Push service method in next generation mobile communication system {Method for Push Service in IMT-2000}

The present invention relates to a push service method in a next generation mobile communication system and a computer readable recording medium storing a program for realizing the method.

Push service provides information necessary for mobile communication terminal (MS) of user who wants to receive service such as weather, stock, sports information, etc. when the next generation mobile communication service is in earnest at the designated time or when any event occurs. If necessary, the service is delivered to the user's mobile terminal.

In the next-generation mobile communication packet network, push services can be provided in two ways. One is "always on" and the other is static (without PDP context activation). We can consider NRPCA (Network Requested PDP Context Activation) method that can support push service by assigning static or dynamic IP address.

However, the "Always on" method always uses the PDP context activation to access the network, receive an IP address, wait for a push service, and currently use IPv4 (Internet Protocol). There was a problem that it was difficult to provide a public IP address to all users through "Always on" until the IPv6 (Internet Protocol Version 6) appeared in a situation where the IP address for Version 4) was insufficient.

In addition, the NRPCA method is not always connected to the user, but in this case, the signal amount (Signaling) is large, there was a problem that the load on the home location register (HLR: Home Location Register) and the entire network.

The present invention has been proposed in order to solve the above problems, and provides information required for a mobile communication terminal (MS) of a user who wants to receive services such as weather, stocks, sports information, etc. in a next-generation mobile communication service at a specified time or any It is an object of the present invention to provide a push service method in a next generation mobile communication system that delivers a user's mobile communication terminal as needed when an event occurs, and a computer-readable recording medium recording a program for realizing the method.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a mobile communication system to which the present invention is applied.

In the figure, "101" is a mobile communication terminal, "102" is a base station, "103" is a base station controller, "104" is a Gateway GPRS Supporting Node (GGSN), "105" is a Serving GPRS Supporting Node (SGSN), " 106 "denotes a home location register (HLR), and" 107 "denotes a push server.

The base station 102 is a radio station established on the land and not moving for communication with the mobile communication terminal 101 or communication by the relay of the mobile relay station.

The base station controller (RNC) 103 is in charge of access to the core network of mobile communication, such as radio resource management, base station operation management.

The Gateway GPRS Support Node (GGSN) 104 serves to link the General Packet Radio Services (GPRS) network to other networks, such as the Internet.

The Serving GPRS Support Node (SGSN) 105 tracks the location of the mobile communication terminal 101 and transmits a packet to the mobile communication terminal 101 in the service area.

The home location register (HLR) 106 is located at a fixed point in the network with respect to the mobile communication terminal 101 and manages an in-network database function for managing subscriber information and location information for providing a service. Is a register.

The push server 107 is connected to the Internet to provide a push service to the user.

The GGSN 104, SGSN 105, home location register 106, and base station controller 103 are connected to a third generation IP backbone.

According to the present invention, when an existing 3GPP IMT-2000 packet subscriber subscribes to a push service, a parameter (for example, "Push Service Allowed") that is not defined in the current 3GPP standard may be converted into a home location register (HLR) 106. Define in to store in the home location register 106 whether to subscribe to the push service.

In this way, the push service subscriber and the general packet service user are distinguished from each other in the service providing method.

Looking at the following Figure 2 will be described in more detail.

2 is a diagram illustrating an embodiment of a push service method according to the present invention.

As shown in FIG. 2, in the push service method according to the present invention, an attachment request is first made from the mobile communication terminal 201 to the SGSN 203 (211).

Next, an authentication process is performed between the mobile communication terminal 201 and the GGSN 205 (212).

The home location register 204 then sends subscriber information to the SGSN 203 (213) and sends a response to the home location register 204 from the SGSN 203 to the home location register 204 (214). In this case, the transmitted subscriber information includes information on the push service subscriber.

In operation 215, a packet data protocol (PDP) context activation procedure is performed.

In this case, when the user who does not subscribe to the push service does not exchange data, the RAB or Iu distribution procedure is performed between the base station controller 202 and the SGSN 203. In this case, the SGSN 203 operates a timer. When is terminated, the PDP context deactivation procedure by the SGSN 203 is performed.

On the other hand, when the user subscribed to the push service has no data exchange, the RAB or lu distribution procedure is performed between the base station controller 202 and the SGSN 203, and the PDP context is maintained.

The present invention as described above in more detail as follows.

The general subscriber may or may not subscribe to the IMT-2000 Push Service through a distributor. In addition, the push service subscription adds a "Push Service allowed" item to the PDP context subscriber information field of the home location register 204 to record whether the push service is provided to the subscriber.

A user who wants to receive packet service in the IMT-2000 network first attaches to the packet network (211). At this time, the subscriber information is sent from the home location register 204 to the Serving GPRS Support Node (SGSN). (213). In this process, the SGSN 203 is informed whether a user who wants to receive a packet service is a user who is subscribed to a push service or a general user. Subsequently, a PDP context activation procedure is performed to obtain routing information (this is called PDP context information) for the data service (215). After the PDP context activation 215, the subscriber is assigned an IP address, and the routing information and the terminal IP address are stored in the PDP context information generated in the SGSN 203 and the GGSN 205. .

After that, the push service subscriber keeps receiving the packet service except when the subscriber does not detach itself or in other error cases, and when the push message is received, the user through the PDP context information. It becomes a structure that can be delivered to (terminal)

However, when the general subscriber does not use the data for a predetermined time after activation of the PDP context, the SGSN 203 obtains information from a base station controller (RNC). In this case, the SGSN 203 operates a timer for a specific time after a predetermined time after obtaining information from the base station controller 202.

If the user does not use data through the network during the timer period, the SGSN 203 deletes the PDP context information in the SGSN 203 and the GGSN 205 by performing a PDP context deactivation process. In addition, the IP address assigned to the user (terminal) can be distributed, thereby saving the network and IPv4 public IP address.

That is, through the above process, after the PDP context activation process is completed, the packet service can be continuously provided to the "always on" user who receives the push service through the assigned IP address, and the packet service to the general user. In the absence of data exchange, the PDP context can be deactivated to release the assigned IP address so that it can be provided to other users.

3 is a diagram illustrating an embodiment of a home location register according to the present invention.

According to the present invention, the following functions have been newly added to the 3GPP standard in order to provide a push service by subscriber management through "Always on".

First, a PDP context deletion function is added to a home location register by adding a field on whether a push service is subscribed and a timer operation for a general user without data exchange of the SGSN 203.

In other words, in addition to the existing "PDP Type", "PDP Address", "Access Point Name", "VPLM Address Allowed" items in the drawing to add the "Push Service Allowed" item to record the push service provided to the subscriber.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention allows a user who is provided with a push service to always allow a service and a general user who is not provided with a push service deactivates the PDP context in the network when the data is not used for a specific time, thereby disabling the IP address. It can save the address and network resources.
