Method and apparatus for processing incoming data {Method And Apparatus for Processing Receipt Data}

One embodiment of the invention relates to a method and apparatus for processing incoming data. In more detail, each time data reception occurs to the mobile communication terminal, first, without allocating a radio resource from the incoming data processing apparatus to the mobile communication terminal, confirming whether a paging processing procedure is being performed first, and checking the result. On the basis of storing the newly received Downlink Protocal Data Unit (PDU) in the buffer and then completing the previously performed paging process, the paging procedure for the downlink PDU stored in the buffer is performed to receive the incoming data. And a method and apparatus for receiving data processing to reduce the load on internal routing processing.

In the mobile communication network, the base station performing the wireless communication and the mobile communication terminal are connected to each other by a wireless link to maintain the continuity of the call even while the subscriber is moving. At this time, the base station controller is connected to the base station to perform a handoff function, the exchange is connected to the base station controller to connect the subscriber's call path and exchange with other exchanges or other communication networks. The exchange is connected to the Internet network through the data service access node, and the data service access node performs a dynamic IP address allocation and routing function for the corresponding mobile communication terminal that wants data service.

The operation of the case where the data service request signal (that is, the packet data call including the address of the corresponding server) is transmitted from the mobile communication terminal will be described briefly. Is transmitted to the data service access node, and the data service access node allocates a dynamic IP address to the terminal based on the received data service request signal and routes it to the internet network, whereby the terminal is connected to the internet network. Allows you to obtain the information from the server.

When data reception occurs to the mobile communication terminal, the data service access node allocates radio resources to the corresponding mobile communication terminal in order to activate the mobile communication terminal in a preservation state to enable data reception. Send the data. However, each time a request for incoming data is received, when internal routing processing is performed on the incoming data to the corresponding mobile communication terminal, traffic is crowded, thereby increasing the system load for processing the incoming data.

In order to solve the above-mentioned problem, an embodiment of the present invention is to store a received downlink PDU in a buffer, and then complete a paging process performed on a buffer so that a paging procedure for the downlink PDU stored in the buffer is performed.

The controller 120 refers to a network end point device that is directly connected to the mobile communication terminal 110 by performing baseband signal processing, wired / wireless conversion, and wireless signal transmission and the like in association with a transmitter. The controller 120 controls the transmitter to allocate and release radio channels for the mobile communication terminal 110, to control transmission output of the mobile communication terminal 110 and the transmitter, and to soft handoff and hard handoff between cells. Determination of handoff, transcoding and vocoding, global positioning system (GPS) clock distribution, and operation and maintenance of the base station are performed.

The packet switch 130 is preferably a Serving GPRS Support Node (SGSN), but is not necessarily limited thereto. The packet exchanger 130 performs a location registration procedure for providing a packet data service, establishes a session, which is a path through which packet data is transmitted and received, and, if necessary, works with the home location register 140 to provide subscriber profile information. Performs the function of sending it. Meanwhile, the packet switch 130 interworks with the home location register 140 through the SS7 network and interworks with the gateway 150 through an intra Public Land Mobile Network (PLMN).

The packet switch 130 according to the embodiment of the present invention receives the first downlink PDU request signal from the gateway 150 and checks whether a paging processing procedure associated with the second downlink PDU is already performed. . The packet exchanger 130 stores the first downlink PDU in the buffer based on the determination result of the paging processing procedure that is already being performed, and when the paging processing procedure for the second downlink PDU already being performed is completed. In addition, the paging procedure for the first downlink PDU stored in the buffer is newly performed. Here, the buffer is a static memory allocated to a preset capacity. That is, when the buffer is a dynamic memory, each time the downlink PDU is stored in the buffer, the memory load is increased because the capacity is dynamically allocated and the downlink PDU is stored.
