Abstract

A method for processing data, in a wireless application protocol for wireless applications using Unstructured Supplementary Service Data (USSD), includes the steps of: (a) receiving data from an upper layer into a Wireless Datagram Protocol (WDP) layer; (b) storing the data received in the WDP layer in step (a) in a common buffer which is commonly used by the WDP layer and a USSD Dialogue Control Protocol (UDCP) layer; and (c) forming packets in the UDCP layer using the data stored in the common buffer in step (b), and then transmitting the packets through the USSD. According to the method, memories for the WDP layer and the UDCP layer, which is an adaptation layer for a Global System for Mobile communication (GSM) USSD bearer, are integrated into one, effectively reducing a required memory size compared to conventional methods in which the WDP layer and the UDCP layer use separate memories.

Claims

1. A method of processing data for wireless Applications using Unstructured Supplementary Service Data (USSD), comprising:

(a) receiving transmission data from an upper layer in a Wireless Datagram Protocol (WDP) layer;

(b) storing the received data in a common buffer, the common buffer being commonly used by the WDP layer and a USSD Dialogue Control Protocol (UDCP) layer; and

(c) forming a transmission packet using the data stored in the common buffer, and then transmitting the packet through the USSD.

2. The method as claimed in claim 1, wherein in operation (c) the UDCP layer forms the packet by adding WDP and UDCP headers to the data stored in the operation (b).

3. The method as claimed in claim 1, wherein in operation (c) the transmission packet is formed in the UDCP layer.

4. A program recorded on a computer readable medium, the program executed in a computer for processing data for wireless Applications using Unstructured Supplementary Service Data (USSD), the program comprising:

(a) receiving transmission data from a layer above a Wireless Datagram Protocol (WDP) layer;

(b) storing the received data in a common buffer commonly used by the WDP layer and a USSD Dialogue Control Protocol (UDCP) layer; and

(c) forming a transmission packet using the data stored in the common buffer, and then transmitting the packet through the USSD.

5. The program recorded on a computer readable medium as claimed in claim 10, wherein in operation (c) the transmission packet is formed in the UDCP layer using the stored common buffer data.
