Problems solved by technology

Therefore, since the RLP frame corresponding to the erroneous frame is repeatedly requested and received a predetermined number of times in a relatively poor radio environment, the overall data transfer speed decreases and the mobile communication system load increases.

Embodiment Construction

[0023] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0024] The RLP frame reception method will now be described with reference to the drawings.

[0025] figure 1 It is a schematic diagram of a general GSM-based mobile communication system. like figure 1 As shown, the mobile communication system based on the GSM method includes terminal equipment (TE) 10 for generating, analyzing, storing, inputting / outputting data. A mobile terminal (MT) 20 is connected with the TE 10 and wirelessly connected with another party to communicate anytime and anywhere. A Base Station / Mobile Switching Center (BS / MSC) 30 communicates with the MT 20 while establishing a communication path with another MT, and controls the following communication system according to the GSM method. An Interworking Function (IWF) 40 connects the BS / MSC 30 with different public networks.

[0026] The MT 20 includ...

Abstract

An RLP (Radio Link Protocol) frame receiving method transmits an RLP frame entirely and quickly in consideration of a radio environment in a mobile communication system. The method discriminates an error frame from the received RLP frame, measures a degree of loss of the received RLP frame and compares the measured degree of loss with a reference value when the error frame is detected. XID parameters (Exchange Identification Parameters) set during an initial stage of reception are varied on the basis of a comparison result and retransmission is then requested of the RLP frame corresponding to the error frame on the basis of the varied XID parameters.

Description

technical field [0001] The present invention relates to a mobile communication system based on the GSM (Global System for Mobile Communications) method, in particular to a method for receiving RLP frames that can transmit RLP (Radio Link Protocol) frames instantly and accurately. Background technique [0002] The mobile communication system enables users to communicate with others at any place and at any time through radio paging and wireless connection while moving within the service area. With the development of mobile communication-related technologies, mobile communication systems can perform data communication as well as voice-level signal communication. There is a mobile communication system utilizing the GSM (Global System for Mobile Communications) method, which is a TDMA (Time Division Multiple Access) method. [0003] Due to the influence of various radio environments, mobile communication systems are very likely to generate data errors because the system transmit...
