specific Embodiment

[0059] This embodiment is a preferred implementation manner of the wireless Modem uplink packet data processing method of the present invention.

[0060] see figure 2 ,Such as figure 2 As shown, the uplink packet data processing method of this embodiment includes:

[0061] The interface driver module receives the data sent by the host;

[0062] S101. The interface driver module applies for a PDDU storage space;

[0063] S102. The interface driver module sets a first offset address;

[0064] First offset address = length of PDDU header + maximum length of PDCP header;

[0065] S103. The interface driver module receives the data sent by the host, acquires uplink packet data from the data sent by the host, and saves it in the packet data storage unit;

[0066] As a preferred implementation of the present invention, in this embodiment, this step may further include:

[0067] S1031, the interface driver module judges the connection mode between the host computer and the wir...

Abstract

The invention discloses a wireless modem uplink packet data processing method, comprising the following steps: when a wireless Modem receives uplink data sent by a host, an interface driver module applies for a PDDU storage space; and in an uplink packet data processing procedure, the interface driver module, an interface adapter module, a PDCP module and an RLC module directly add encapsulation information of the current layer to a PDDU and / or modify offset addresses stored in uplink packet data and data lengths, and then send the offset addresses and the data lengths to the next module to achieve the processing of each module to the uplink packet data. According to the technical scheme of the invention, the number of operations of data copy and storage as well as storage space application and release in the uplink packet data processing procedure can be reduced, and the efficiency of the uplink packet data processing procedure can be effectively improved.

Description

technical field [0001] The present invention relates to the data processing technology of the mobile communication system, in particular to an uplink packet data processing method in a wireless modem (abbreviated as wireless Modem) of the mobile communication system. Background technique [0002] In the terrestrial mobile communication system or satellite mobile communication system, in order to meet the user's access to the Internet based on the Internet Protocol (abbreviation, IP), the connection between the wireless Modem and the host needs to be designed to be logically compatible and transmit two kinds of data. Packet data in format: one is Point-to-Point Protocol (PPP) packet data encapsulated in High-level Data Link Control (abbreviation, HDLC) frame format. IP packet data, this connection method is called virtual Ethernet method. Among them, in the first type of packet data packet, according to the PPP protocol, IP packet data is encapsulated in the HDLC frame forma...
