Flow control of short message service messages in a cellular telephone network

摘要

Measurements of the load being carried on the control channel of a cellular telephone network air interface are made and then processed to identify a maximum permitted short message service message length for control channel transmission. Short message service messages with lengths less than the permitted maximum are authorized for transmission over the control channel. Any short message service message having a length exceeding the determined maximum length, however, is refused authorization for control channel transmission. The refused messages are either saved for control channel transmission at a later time when the measured loading permits or transmitted over the traffic channel portion of the air interface.
