Equally when handling other message, for example, there are similar problem in SECURITY COMMAND COMPLETE message and UPLINK DIRECT TRANSFER message, RB SETUP COMPLETE and UPLINKDIRECT TRANSFER message, need promptly to wait for that all PDU that receive previous message are by the RLC ACK message after collecting, just send next message, thereby introduce more time delay.
First kind of handshaking procedure be by Radio Resource control (RRC) entity that is in layer three and Radio Link control (RLC) entity of being in layer two finish information between UE and RNC alternately.UE is as transmitting terminal, and RNC is as receiving terminal, the information interactive process of the two can be abstract for as shown in Figure 2:
The RRC entity of UE is delivered to the RLC entity of UE with RRC MESSAGE message, and the RLC entity of UE is responsible for message is split as a plurality of PDU, sends to the RLC entity of RNC respectively.
The RLC entity of RNC receives a plurality of PDU that the RLC entity of described UE sends to, and after confirming to collect article one RRC MESSAGE message, it is uploaded to the RRC entity of RNC;
The RLC entity of RNC is received PDU, feeds back to the ACK of UE RLC entity to PDU;
The RLC entity of the RLC entity reception RNC of UE returns the ACK of the segmentation PDU of first RRC MESSAGE message, when knowing the RLC ACK that whole PDU obtain, this information is reported the RRC entity of UE;
After the RRC entity of described UE is known this information, send a piece of news down.
After the RRC of RNC entity receives all RRC MESSAGE message that the RLC entity of neat RNC submits, trigger and the relevant flow process of article one RRC MESSAGE message.
Second kind of handshaking procedure comprises that RNC is sending RB SETUP message to behind the UE, and to the process of NodeB transmission RL RECONFIG COMMIT message, its signaling process comprises as shown in Figure 3:
Step 2, RNC internal resource are prepared.
After step 4, NodeB finish internal resource foundation, send RL RECONFIG READY message to RNC.
Step 7, RNC send RL RECONFIG COMMIT message to NodeB.
In the 7th step, when RNC is ready for sending RL RECONFIG COMMIT message to NodeB, collect RB SETUP earlier in order to guarantee UE, can wait for the ACK that the whole PDU of RB SETUP message are collected, send RL RECONFIG COMMIT message again to NodeB.Be equivalent to exist the time delay of Tack.
Second kind of handshaking procedure is to finish the mutual of information between UE and RNC by RRC entity that is in layer three and the RLC entity that is in layer two.RNC is as transmitting terminal, and UE is as receiving terminal, the information interactive process of the two still can be abstract for as shown in Figure 2:
The RRC entity of RNC is delivered to article one RRC MESSAGE message the RLC entity of RNC;
The RLC entity of RNC is responsible for message is split as a plurality of PDU, sends to the RLC entity of UE respectively;
The RLC entity of UE receives a plurality of PDU that the rlc layer of described RNC sends to, and after confirming to collect article one RRC MESSAGE message, it is uploaded to the RRC entity of UE;
After the RRC entity of UE receives article one RRC MESSAGE message, feeding back ACK message, and send the RLC entity of RNC to by the RLC entity;
The RLC entity of the RLC entity of RNC by UE returns in first RRC MESSAGE message all RLC ACK of PDU, knows whether UE has collected whole PDU unit of first RRC MESSAGE message.Then this information is reported the RRC entity of RNC;
After the RRC entity of described RNC is known this information, send a piece of news down.
After the RRC of UE entity receives all RRC MESSAGE message that the RLC entity of neat UE submits, trigger and the relevant flow process of article one RRC MESSAGE message.
By the technical scheme of above-mentioned prior art as can be seen, after the RRC of transmitting terminal entity sends article one RRC MESSAGE message, after must waiting for the RLC ACK message of the whole PDU of article one message that receiving terminal feeds back, just sending down, therefore a piece of news exists the long time delay that continues to the RLC entity.
