METHOD AND APPARATUS FOR AVOIDING DATA LOSS DURING A PPP RENEGOTIATION ON A UM INTERFACE

摘要

A method and a wireless communication device capable of flow controlling data to be sent from a TE2 (102) device over a Rm interface when PPP renegotiation occurs over a U.m interface. Flow control is asserted by the MT2(104) device by means of manipulating electrical signaling of a physical interface between the MT2(104) device and the TE2(102) device. A second embodiment provides a method and a wireless communication device for buffering data on the MT2(104) device when the PPP renegotiation of the U ..m interface occurs. In a third embodiment, data is buffered when the PPP renegotiation of the U m interface occurs. When an amount of free buffer space is less that a predetermined threshold, flow control is asserted to the TE2(102)device. (figure.1)
