The value of the data segment directly determines how the decoding module parses the subsequent packet. The data value of the field. When 10 indicates a request packet, the corresponding 403 data segment is represented as a request query short number, and the data of the 404 data segment is represented as the number of the called terminal that issued the USSD request.

After receiving the USSD request packet, the USSD server performs data parsing according to the packet format definition, obtains the group short number in the data packet, and the number of the called terminal that requests the query, and then performs further data processing.

(2) The data format definition of the USSD response phase (that is, the above USSD response packet) is mainly composed of four parts:

The packet header is consistent with the request phase packet header (ie, data segment 401) and is also *1101. The data segment 405 is used to identify the packet type, and 11 indicates that the packet is a group short number query response packet, which determines the data segment subsequent data segment allocation of the data packet. The subsequent 406 data segment indicates the full number corresponding to the group short number obtained in the query result. If the data segment is empty, it means that the user who initiated the request does not have the right to query the group short number. The 407 data segment represents the user name corresponding to the data trombone, and the user name can be used for caller ID and directory update of subsequent terminals.
