Memory operating managing method and memory operating managing device

Abstract

The invention discloses a memory operating managing method comprising the steps: a subnetwork dependence convergence protocol (SNDCP) layer saves SNDCP parameters obtained by partitioning and identifying compressed uplink data in a preset SNDCP data queue and sends the characteristic parameters of the SNDCP data queue, which are obtained after saving the SNDCP parameters, to a logical link control (LLC) layer; the LLC layer saves the characteristic parameters of the SNDCP data queue in a preset LLC data queue and sends the characteristic parameters of the LLC data queue, which are obtained after saving the characteristic parameters of the SNDCP data queue, to a radio link control (RLC) layer; after applying for the radio resource, the RLC sequentially calls back LLC callback function and SNDCP callback function according to the received characteristic parameters of the LLC data queue so as to acquire an LLC data packet, process the LLC data packet and send the LLC data packet through the applied radio resource. The invention also discloses a memory operating managing device. Due to the adoption of the memory operating managing method and the memory operating managing device, the space of the memory can be effectively saved.

Description

technical field [0001] The invention relates to memory operation management technology, in particular to a method and device for memory operation management in the general packet radio service (GPRS) transmission plane protocol layer. Background technique [0002] In the GPRS terminal system, methods such as reducing message transmission between modules, reducing system calls, and reasonable memory operation management can be used to improve system efficiency and smoothness of sending data. One of the memory operation management methods is described below. [0003] In the whole GPRS terminal system, the transmission plane protocol layer mainly includes the Subnetwork Dependent Convergence Protocol Layer (SNDCP), Logical Link Control Layer (LLC) and Radio Link Control Layer (RLC). Among them, SNDCP provides data access functions belonging to different types of protocols, and performs operations such as compression of data and control parts, data segmentation and assembly; LL...

Problems solved by technology

[0008] 2. The application for the memory in the data area of ​​the transmission plane, the application for the memory in the data area of ​​the control plane, and the application for the memory of the message when sending a message all apply to the same memory. The data on the control plane cannot be applied for in memory, resulting in some control failures;

[0009] 3. A large amount of data will accumulate in the RLC, thereby increasing the amount of calculation of the RLC, thereby reducing the efficiency of data transmission;

[0010] 4. In LLC, most of the data needs to be encrypted. Generally, encryption takes up resources. If a data transmission fails, the LLC link will be rebuilt, and all LLC data packets previously sent to RLC will be cleared. In this way Resulting in useless work previously done by the LLC

[0011] In addition, the existing technology also uses the memory pool method to manage the memory, which can avoid some shortcomings of the above method, but still cannot avoid a large number of dynamic memory application releases and cumbersome memory pool operations.
