  • METHOD AND DEVICE FOR RELEASING COMMON E-DCH RESOURCE
    Publication number: 20150201458
    Abstract: The present invention provides a method and a device for releasing a common E-DCH resource. A base station receives time information of an implicit resource releasing timer sent by a base station controlling device, so that the base station releases or does not release, according to the time information of the implicit resource releasing timer, a common E-DCH resource occupied by a terminal. Because the base station no longer releases or does not release, only according to SI whose value is 0, the common E-DCH resource occupied by the terminal, a problem in the prior art that the terminal needs to compete again if there is data to be sent so as to obtain the common E-DCH resource because the base station improperly releases the E-DCH resource occupied by the terminal, can be avoided, thereby reducing delay in sending the data.
