Description
Technical field
The present invention relates to the communications fields, more particularly to a kind of method and apparatus for coordinating base station and terminal serial number.
Background technique
In long term evolution (Long Term Evolution, LTE) wireless communication system, with terminal geographic position
Constantly variation, in order to guarantee the continuity of business, terminal needs switch between different community.Particularly, for confirming mould
Formula (Acknowledged mode, AM) business, in handoff procedure, source cell is needed the sequence number (Serial of business
Number, SN) pass through signaling message informing purpose cell.It sees shown in Fig. 1, hand off signaling stream is illustrated so that X2 switches as an example
Journey:
Step 100: terminal send measurement report (Measurement Report) to source base station (Evolved Node B,
eNB)。
Step 110: source eNB sends switching request (HANDOVER REQUEST) signaling and gives target eNB.
Step 120: target eNB sends Handover Request Acknowledge (HANDOVER REQUEST ACKNOWLEDGE) signaling to source
eNB。
Specifically, target eNB switching be ready to complete after send (HANDOVER REQUEST ACKNOWLEDGE) signaling to
Source eNB.
Step 130: source eNB issues wireless resource control connection reconfiguration (RRC Connection
Reconfiguration) signaling is to terminal.
Step 140: eNB state transfer (the SN STATUS TRANSFER) signaling that transmits Sequence Number in source gives target eNB.
Step 150: terminal sends configuration and completes (RRC Connection Reconfiguration Complete) signaling
Give target eNB.
Step 160: target eNB transmitting path convert requests (PATH SWITCH REQUEST) signaling gives mobile management reality
Body (Mobility Management Entity, MME)；
Step 170:MME reverse-path convert requests confirm (PATH SWITCH REQUEST ACKNOWLEDGE) signaling
Give target eNB.
Step 180: target eNB sends user's context release (UE CONTEXT RELEASE) signaling and gives source eNB.
In real network environment, due to transmission packet loss, eNB abnormality processing, MME abnormality processing etc., it may appear that cut
Change that destination is later to receive or can not receive the case where including the signaling message of SN.
Such case will lead to hand off signaling surface current journey and be completed, but service surface can not extensive data the phenomenon that transmitting again.
And once there is the situation, even across subsequent normal switching flow, AM business can not also be restored.
Currently, terminal is in mesh after target eNB receives RRC Connection Reconfiguration Complete
Mark eNB can carry out uplink and downlink data transmission.For AM business, at this time if target eNB does not receive the SN of source eNB transmission
STATUS TRANSFER, then target eNB will with initial SN and initial Hyper Frame Number (Hyper Frame Number, HFN) to it is upper,
Downlink data is handled.
However, under the prior art, after uplink AM data reach, it may appear that the case where SN exit window abandons and decryption fails,
Lead to uplink data transmission interrupt；After downlink AM data are sent to terminal, there is terminal and check that SN exit window abandons and decrypt failure
Situation leads to downlink data transmission interrupt.Once there is the problem, even if later handover processes SN STATUS TRANSFER can be normal
Transmission all will be unable to restore with the business data transmission that AM is carried out.
Summary of the invention

It is initialized with Hyper Frame Number HFN, and, disappear to terminal transmission comprising reconfiguring the RRC connection reconfiguration of field completely and setting
Breath, the SN and HFN of instruction terminal are initialized.
After target eNB and terminal execute initialization operation, the SN of target eNB and the SN of terminal are consistent, target eNB's
HFN is consistent with the HFN of terminal.
Further, purpose eNB data packet is numbered according to the SN after initialization, and according to HFN pairs after initialization
Data packet is encrypted, and encrypted data packet is sent to terminal；
And the data packet returned using the SN monitor terminal after initialization, and according to the HFN after initialization to listening to
Data packet be decrypted.
For example, purpose eNB is numbered from SN=0 for downlink data packet, and encryption is sent to end since HFN=0
End, for upstream data packet, purpose eNB begins listening for the data packet that terminal is sent from SN=0, and decrypts since HFN=0.

Specifically, thening follow the steps 330 if received, otherwise, step 340 is executed.
Step 330: being grouped data convergence protocol (Packet Data Convergence according to normal process
Protocol, PDCP) data processing.
Step 340: starting waiting timer (Twait).
Step 350: judging whether to receive SN STATUS TRANSFER message in preset time range.
If do not received, 360 are thened follow the steps, otherwise, executes step 330.
In general, preset time range is arranged within 500ms, as long as receiving SN STATUS in 500ms
TRANSFER message then carries out PDCP data processing according to normal process.
Step 360: target eNB executes initialization operation to the PDCP information of the terminal saved in itself PDCP layers, and to
Terminal, which is sent, sets message comprising the RRC connection reconfiguration for reconfiguring field completely, and instruction terminal executes the PDCP layer of terminal local
Initialization operation (referred to as executes switching within cell signaling process).
During executing step 360, target eNB is indicated in the PDCP information of the terminal saved in itself PDCP layers
SN and HFN is initialized and the SN and HFN of instruction terminal are initialized, in this way, making target eNB's
SN, HFN and SN, HFN of terminal are consistent.
