Common signaling channel is that network side and terminal are not being set up speciallyCarry out with before channel the transmission channel that Signalling exchange uses, common signaling channel can carry multiple simultaneouslyThe Signalling exchange of terminal and network side, common signaling channel can be divided into again reverse common signaling according to uplink and downlinkChannel (corresponding up) and Forward Common Signaling Channel (corresponding descending). Dedicated Signaling Channel is network sideReceiving after the service request of terminal, is the dedicated channel resource of this terminal distribution, only for carrying this terminalTraffic signaling mutual, it is (right that Dedicated Signaling Channel can be divided into Reverse Dedicated Signaling Channel again according to uplink and downlinkShould be up) and Forward Dedicated Signaling Channel (corresponding descending).
Be illustrated in figure 1 network side sends process from the Forward Dedicated Signaling Channel message of band confirmation to terminal, bandThe message of confirming refers to, transmitting terminal sends to receiving terminal that receiving terminal after message need to be to transmitting terminal feedback messageThe message of accepting state. The message sending taking network side to terminal is regular protocol Data Unit (ProtocolDataUnit, PDU) be example, network side sends sequence number as the message of N to terminal, if in time interval TNetwork side does not receive the receiving status information of the message that the sequence number of terminal feedback is N, and network side is to terminal weightNewly send sequence number as the message of N. In the time that the sending times of the sequence number message that is N reaches certain thresholding, network sideStop sending sequence number as the message of N to terminal. In the time that the message sequence number of network side transmission reaches (N+X) mould 8,X represents that network side, to the parallel at most message number sending of terminal, is N's because network side does not receive sequence numberThe receiving status information of message, therefore network side can be to the send sequence number sequence number (N+X) of N association of terminal yetThe message of mould 8 correspondences.
For end side, the message that terminal Receive sequence number is N, now, if message sink mark corresponding to sequence number NWill position is no, represents that terminal did not receive the message that sequence number is N, and terminal is determined disappearing that the sequence number of reception is NBreath is non-repetition message, and it is to represent terminal Receiving Order that the message sink flag bit that sequence number N is corresponding is set toNumber be the message of N, the message that is N by sequence number is submitted to upper strata and processes, and by the sequence number of sequence number N association (N+X)The message sink flag bit of mould 8 correspondences is set to no, makes that terminal is follow-up can by the sequence number of reception be correctly(N+X) message of mould 8 is judged to be non-repetition message. If the message sink flag bit that sequence number N is corresponding is yes,Represent that terminal had received the message that sequence number is N, terminal judges that the message that the sequence number of reception is N disappears as repeatingBreath, the message that is N by this sequence number abandons, and the message of sequence number (N+X) mould 8 correspondences to sequence number N associationReceiving flag position does not arrange. Therefore, if the message that the sequence number that terminal receives is N is non-repetition message, andBe judged to be to the message error that terminal is N by sequence number repetition message, the message that sequence number is N will be dropped,Further, make the follow-up message error that is (N+X) mould 8 by the sequence number receiving of terminal and be judged to be repetitionMessage, causing sequence number is that the message of (N+X) mould 8 is dropped.
In sum, message sink end adopt current repetition message determine mechanism, due to eat dishes without rice or wine wait environment because ofElement, may be judged to be repetition message mistakenly by the non-repetition message receiving, and causes this non-repetition message to be lostAbandon. Further, also can cause receiving terminal by the non-repetition message of this non-repetition message association of follow-up receptionBe judged to be mistakenly repetition message, cause message to abandon.
