The rapid development of computer, electronic and communication technologies is a driving force behind the provision of diverse wireless communication services through wireless communication networks. The most basic wireless communication service is a wireless voice call service, which enables an MS user to make a voice call wirelessly regardless of time and place. Wireless internet services are also provided, which enable users to communicate data via the internet through a wireless communication network anywhere while the users are moving. In particular, a Short Message Service (SMS) can transfer a text message of a limited length between MSs, in other words, between MSs in an idle mode, regardless of a communication state of a receiving MS. Typically, SMS limits text messages to about 80 bytes on a liquid crystal screen. At present, the rate of use of SMS has increased dramatically from personal use to business use. In addition to simple message exchange between individuals, SMS has recently found a wide range of uses in mass messaging, scheduled message transmission, email receipt alerts, personal credit management, financial information alerts, and the like.
In order to solve the above technical problems in the prior art, paired and unpaired frequency spectrums cannot be used comprehensively, the frequency spectrum use efficiency is improved, the service provision capability is enhanced, and the comprehensive cost of the base station and the terminal is reduced.
