an initialization process: the OAM process of the master control panel needs to execute an initialization process at the initial start-up stage, and the specific steps are as follows.
Step 1, creating a database table, defining each field in the database table, wherein the field contains a transmission control operation type (inquiry, modification, deletion or specific service flow, such as deleting and building a cell) and an operation parameter.
Step 2, calling a registration interface to complete a registration process of a registration node task; the interface is used for associating tasks on a master control disk with a database table and transmission control messages, and a function return value is a database management node pointer, and the specific steps are as follows:
step 2.1, applying for a memory, and creating a registration node task, wherein a data structure schematic diagram of the registration node task is shown in fig. 2.

For example: the initialization process creates a 4G disk related database table, and the task 1 relates to the query process of the cell frequency point parameters of the 4G disk database table. If the OAM receives a message of a background network manager, the message is a cell frequency point for inquiring a 4G disk, the OAM only needs to operate a database and insert a record, the content of the record contains a transmission control operation type (inquiry) (please note that the operation type is not the operation type of the database), an operation parameter (cell frequency point) database monitors the change of the database monitored by a task, an insert record is found in a 4G disk database table, a global registration linked list is traversed, the task 1 is found to be associated with the inquiry process of the cell frequency point parameter of the 4G disk database table, then a message is sent to the task 1, and the message content is 'inquiry cell frequency point'.

step 2, locking;
step 3, deleting the registration management node from the global linked list;
and 4, unlocking to finish de-registration.
Referring to fig. 5, a control message transmission system is provided, which includes a front-end device and a background network manager, where the front-end device is integrated with a master control disk and multiple service disks.
