Embodiment Construction

[0041] Please refer to FIG. 4 , which is a schematic diagram of the data buffer structure of the present invention. The data buffer structure is the uplink data buffer structure of the SGSN-SNDCP non-confirmation mode of the present invention. The present invention adopts a two-layer buffer management mechanism. Each SN-PDP buffer stores a pointer to a packet buffer. All packet buffers belonging to the same SN-PDP buffer are connected in series in the form of a sequential linked list. Each packet buffer stores a pointer to a fragment buffer. Pointer, all fragment buffers belonging to the same packet buffer are connected in series in the form of sequential linked list. The number of buffered packets (N-PDUs) attached to each SN-PDP buffer is limited, for example, a maximum of 4 may be specified. The number of fragment (SN-PDU) buffers attached to each packet buffer is limited, and the maximum number of fragments cannot exceed the maximum number of fragments of a packet suppor...

Abstract

The utility model discloses a data loss solution, which comprises 1. Create a SN -PDP buffer; 2. Each SN -PDP buffer is connected with one or a couple of N-PDU buffers which can receive the SN -PDU piece as per the packet number of SN PDU piece. When the receiving timer of N-PDU buffer is timing out and failing to receive all SN -PDU pieces, the N-PDU can release the buffer occupied by the SN -PDU piece; 3. Each N-PDU buffer is connected with one or a couple of SN -PDU piece buffers; 4. Each SN -PDP buffer is connected with one or a couple of buffers which lose the memory. The packet number of the SN -PDU piece without the complete package shall be left in the memory buffer via SGSN. Also, as per the packet number, the unconfirmed upper pieces with the same packet numbers can be discarded. The utility model solves the upper data package loss of SGSN via non-confirming method.

Description

technical field [0001] The invention relates to a method for reducing data loss in a mobile communication system, in particular to a method for reducing uplink data loss in a non-confirmed transmission mode on core network service support node equipment in a general packet radio service system. Background technique [0002] In recent years, various GSM (Global System for Mobile Communications, Global System for Mobile Communications) operators have begun to gradually expand many GSM network systems to support GPRS (General Packet Radio Service, General Wireless Packet service) system, which greatly improves the data service rate. Specifically, MS (Mobile Station, mobile terminal) needs to support a set of GPRS protocol stack suitable for terminal equipment, and BSC (Base Station Controller, base station control system) needs to add PCU (Packet Control Unit, packet control unit) equipment , to realize the protocol stack communicating with the core network GPRS equipment, nee...
