Method and system for transmitting optional field in data packet

Abstract

The method can correctly indicate whether or not the optional fields exist in the data packet in case of not adding the extra field. In the invention, the different filling modes are used to indicate whether or not the optional fields exist; the typical filling mode is all bits are 0 or 1.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to the transmission of optional fields in data packets. Background technique [0002] UMTS (Universal Mobile Telecommunication System, Universal Mobile Telecommunication System) is one of the main third generation mobile communication (The Third Generation, "3G" for short) systems in the world at present. The UMTS system consists of three parts, namely the core network (Core Network, referred to as "CN"), Universal Mobile Telecommunications System Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, referred to as "UTRAN") and user equipment (User Equipment, referred to as " UE") composition. The interface between CN and UTRAN is defined as Iu interface, and the interface between UTRAN and UE is defined as Uu interface. [0003] The earliest protocol version of UMTS is R99. In this version, the bearing of uplink and downlink services is based on dedicated chan...

Problems solved by technology

[0016] In practical applications, the above scheme has the following problems: UE sends redundant SI, which increases unnecessary processing burden on UE and Node B

Therefore, at times other than normal triggering of SI, due to the limitation of the MAC-e PDU format, UE must send SI reports to Node B. In order to send SI reports, UE needs to update SI reports, and Node B needs to renew SI reports based on these redundant SI reports. Evaluate uplink resource status and allocate resources, increasing unnecessary processing burden on UE and Node B
