Problems solved by technology

[0007] (1) In the scheduling process of system messages, there is no difference in the importance of system information blocks;
[0008] (2) For the scheduling of system information blocks, it is required to first realize the encoding of system messages and obtain the length after encoding, thereby increasing the requirements for system message scheduling and making the system message scheduling process complicated;
[0009] (3) Whether the system information block is segmented or not and the scheduling of the system information block requires manual participation, which makes the system message scheduling difficult to be accurate and unified;
[0010] (4) The cascade connection between the system information blocks is not realized, so that the system information blocks with a smaller length waste the capacity of the broadcast channel;
[0011] (5) In the case of system information configuration modification, it is necessary to manually re-complete the scheduling of all system information blocks, resulting in duplication of labor and low efficiency of scheduling system information

Abstract

The invention discloses a system message dynamic scheduling method in a broadband code division multiple access system, which is characterized in that the method includes the following steps: A. determining the master information block (MIB) and the scheduling information block (SB) in the system message, The priority of each system information block (SIB) and the period upper limit and lower limit corresponding to each priority; B. Obtain the size after compression and encoding of each SIB, and segment each SIB with the transport block size as the unit, according to each Segment number of SIB predicts MIB and SB; C. Concatenate MIB, SB and SIB in order of priority from high to low, and re-segment SIB according to the result of concatenation during concatenation; D. Determine the update period of the system message in the order of priority from high to low and the corresponding upper and lower limits of the period, and allocate the sending time in the broadcast channel for each system message according to the update period and the segmentation and cascading conditions.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, in particular to a method for dynamic scheduling of system messages in a mobile communication system. Background technique [0002] As a spread spectrum mobile communication technology, Code Division Multiple Access (CDMA) was originally mainly used in the field of military communication. Due to its excellent performance, this technology has been increasingly widely used in the field of civilian communication. Currently, there are practical examples of operating commercial CDMA cellular mobile communication systems in telecommunication networks. [0003] In a cellular mobile communication system, the entire network is composed of several divided cells, and different cells are configured with different cell configuration attributes according to actual conditions. The configuration attribute may specifically include the public land mobile network (PLMN) area to which the cell belongs,...
