METHOD AND APPARATUS OF COMMUNICATION MODE SWITCH AND SYSTEM |
| 摘要 |
Disclosed herein are an apparatus and method, the method includes: determining a mode switch manner by an eNB according to a predetermined policy; transmitting a first mode switch command by the eNB to UE in D2D communication if the mode switch manner is no packet data convergence protocol (PDCP) parameter exchange, and resetting all PDCP transmitter parameters and PDCP receiver parameters by the eNB to be 0; and transmitting a mode switch preparation command by the eNB to UE in D2D communication if the mode switch manner is full PDCP parameter exchange, so that the UE reports PDCP transmitter parameters, PDCP receiver parameters and a PDCP status report or reports a first missing PDCP reception SN and a corresponding HFN, thereby completing PDCP parameter setting and mode switch. |

1. An eNB, comprising:
a determining unit configured to determine a mode switch manner according to a predetermined policy; and a processing unit configured to transmit a first mode switch command to UE in D2D communication if the mode switch manner determined by the determining unit is no PDCP parameters exchange, and reset all PDCP transmitter parameters and PDCP receiver parameters to be 0. |
