A system and related method for processing messages may include one or more processors and a memory in communication with the one or more processors. The memory may include a communications module, a deduplication module, and a message processing module. The communications module may cause the one or more processors to send or receive a first message via a first transmission protocol having a first temporary identifier value and a second message via a second transmission protocol having a second temporary identifier value. The deduplication module may cause the one or more processors to determine if the first temporary identifier value is related to the second temporary identifier value. In the event, the identifier values are related, the second message is discarded. Thereafter, the message processing module may cause the one or more processors to process the first message.

Wireless communication device

A communication device is used in a mobile communication system switching alternately two communication time zones of a control channel (CCH) time zone in which communication using a control channel (CCH) is performed and a service channel time zone in which communication using a service channel is performed. A CCH transmission processor section transmits data using the control channel. When a generated data by a data generator section is determined by an importance determiner section to be equivalent to a data having a high-importance level, the generated data is transmitted in the CCH time zone by the CCH transmission processor section. By contrast, when the generated data is determined to be equivalent to a data having a low-importance level, the generated data is transmitted in the SCH time zone by the CCH transmission processor section.

The service provision device designates a communication method for performing the communication with the mobile object side device using the service channel indicated by the service start information. The service provision device transmits the service start information designating an immediate start method in a latter half of the control channel time period.
