Embodiment
Core of the present invention is in net system switching process, abandons the segmented data block that repeats in the handoff procedure.In the specific implementation, can the segmented data block of packet abandon with receiving completely from the cell-of-origin in the hand-off execution process by terminal, perhaps the repeating data piece that receives from Target cell in the hand-off execution process is abandoned by terminal, in addition, can also be terminal by with the Signalling exchange of Target cell, the data message that the notification target sub-district has received, Target cell abandon the segmented data block of repetition when sending packet.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, Fig. 1 shows the principle of first embodiment of the invention:
During beginning, terminal normally receives packet from the cell-of-origin, switches to begin to carry out after receiving preceding two segmented data blocks of packet 2.T1 is for switching the initial moment, and promptly terminal disconnects and being connected of cell-of-origin, and T2 finishes constantly for switching, and promptly terminal has been set up and being connected of Target cell, and time of execution is switched in [T1, T2] interval expression.
When disconnecting with being connected of cell-of-origin, terminal receives only two segmented data blocks of packet 2, concerning packet 2, receives not exclusively, is regarded as invalid data block, and terminal abandons this two segmented data blocks.
Set up with being connected of Target cell after, terminal restarts to receive packet 2.
Because terminal abandons from the cell-of-origin and receives incomplete data block, has eliminated the repeating data piece, thereby has guaranteed the integrality of packet.
Fig. 2 shows the realization flow of the inventive method first embodiment, may further comprise the steps:
Step 201, switching begin to carry out, and the terminal disconnection is connected with the cell-of-origin.
Step 202, terminal will not receive completely, and segmented data block abandons.
When terminal disconnects with being connected of cell-of-origin,, then need it is abandoned if end side does not receive segmented data block completely; If terminal is when disconnecting with being connected of cell-of-origin, just in time receiving all segmented data blocks of a complete packet or the minimum data unit of reception is a packet, does not then need to abandon operation.
When abandoning segmented data block, can adopt following dual mode:
(1) segmented data block of packet does not carry out Timing Processing to terminal to receiving completely in the buffer memory, after timing arrives, the segmented data block of the packet in the buffer memory is abandoned.Wherein, can set timing and be no more than break period, promptly terminal receive on the cell-of-origin last data block to terminal in the time that begins on the Target cell to receive between the data block.
(2) in the receiver window of terminal setting, do not receive data after, terminal will not receive completely that the segmented data block of packet abandons.
Step 203, terminal foundation are connected with Target cell, and receive the segmented data block of packet or packet from Target cell.
Terminal set up with being connected of Target cell after, terminal is capable to receive data from Target cell.Needs do not carry out segmentation if the size of high level data bag satisfies the requirement that transmits on physical layer, and the data that receive from Target cell of terminal are exactly a complete packet so.And if high level data Bao Taida can't satisfy the requirement that transmits on physical layer, Target cell just need carry out segment processing with it so, then segmented data block is sent to terminal, and what at this moment terminal received is exactly segmented data block.
After step 204, packet received fully, packet or segmented data block that end-on is received were handled.This processing procedure comprises segmented data block is decrypted, sorts, removes processing such as packet header, extracts data net load unit then.High-rise data net load unit with extraction is reassembled as complete packet.
Referring to Fig. 3, Fig. 3 shows the principle of second embodiment of the invention:
During beginning, terminal normally receives packet from the cell-of-origin, switches to begin to carry out after receiving preceding two segmented data blocks of packet 2.T1 is for switching the initial moment, and promptly terminal disconnects and being connected of cell-of-origin, and T2 finishes constantly for switching, and promptly terminal has been set up and being connected of Target cell, and time of execution is switched in [T1, T2] interval expression.
When disconnecting with being connected of cell-of-origin, terminal receives only two segmented data blocks of packet 2, concerning packet 2, receives not exclusively, and after being connected of disconnection and cell-of-origin, terminal is preserved this two segmented data blocks.
Set up with being connected of Target cell after, terminal restarts to receive packet 2.
The segment data block message of all packets 2 that terminal will receive and two segmented data blocks preserving previously compare, and judge whether current data block receives, if do not receive, then preserve, otherwise abandon.As data block S2 among the figure, the data block S1 that had received from the cell-of-origin with terminal repeats, and through after relatively, S2 abandons with data block.
Fig. 4 shows the realization flow of the inventive method second embodiment, may further comprise the steps:
Step 401, terminal disconnection are connected with the cell-of-origin.
Step 402, terminal are preserved and are not received the segmented data block of packet completely.
If this moment, end side did not receive segmented data block completely, then it is kept in the buffer area; If end side is when disconnecting connection, just in time receiving all segmented data blocks of a complete packet or the minimum data unit of reception is exactly a packet, so directly this packet is treated to the high level data unit.
Step 403, terminal set up with being connected of Target cell after, from the segmented data block of Target cell reception packet or packet.
Terminal set up with being connected of Target cell after, terminal is capable to receive data from Target cell.Needs do not carry out segmentation if the size of high level data bag satisfies the requirement that transmits on physical layer, and the data that receive from Target cell of terminal are exactly a complete packet so.And if high level data Bao Taida can't satisfy the requirement that transmits on physical layer, Target cell just need carry out segment processing with it so, then segmented data block is sent to terminal, and what at this moment terminal received is exactly segmented data block.
Step 404, terminal compare the packet that receives from Target cell or the segmented data block of packet, judge whether the new segmented data block that receives is identical with the segmented data block that receives from the cell-of-origin of its preservation from the Target cell.
In this step, after terminal receives the packet or segmented data block of Target cell transmission, can compare judgement by the sequence number of packet or segmented data block, if comparative result shows this packet or data block and received and be kept at from the cell-of-origin the memory block, then enters step 405; Otherwise, enter step 406.
Step 405, this packet or segmented data block are abandoned.
Step 406, this packet or segmented data block are kept in the memory block.
After step 407, packet received fully, the packet that end-on is received or the segment data packet of packet were handled.This processing procedure comprises segmented data block is decrypted, sorts, removes processing such as packet header, extracts data net load unit then.High-rise data net load unit with extraction is reassembled as complete packet.
In the evolution system handoff procedure, in order to guarantee harmless the switching, need to use data forwarding mechanism, promptly the cell-of-origin packet that sends that will fail is forwarded to Target cell, and then is retransmitted to terminal by Target cell.In forwarding and retransmission processes, Target cell need retransmit whole packet, if and in retransmission processes, by the segmented data block notification target sub-district of terminal with its packet that successfully receives, make Target cell no longer retransmit these segmented data blocks, then can guarantee under the prerequisite that packet is not lost, not only can avoid terminal to receive the data block that repeats, but also can further improve efficiency of retransmission.
With reference to Fig. 5, Fig. 5 shows the realization flow of the inventive method the 3rd embodiment, may further comprise the steps:
If this moment, end side did not receive segmented data block completely, then it is kept in the buffer area; If end side is when disconnecting connection, just in time receiving all segmented data blocks of a complete packet or the minimum data unit of reception is exactly a packet, so directly this packet is treated to the high level data unit.
After Target cell obtains these information, at first needs are carried out segment processing to the packet that terminal sends according to the segmentation control information of packet, according to the serial number information of packet or segmented data block, Target cell knows that terminal has successfully received which packet and segmented data block.Therefore, the segmented data block of the segmented data block same sequence number that received with terminal after the segmentation can be abandoned, and the packet and the segmented data block that only those terminals are not received send to terminal.
After step 507, packet received fully, terminal was handled the packet that receives or the segmented data block of packet, and is reassembled as packet at high level.This processing procedure comprises segmented data block is decrypted, sorts, removes processing such as packet header, extracts data net load unit then.High-rise data net load unit with extraction is reassembled as complete packet.
