Abstract

The present invention provides a method for realizing the grouping data transmission, which comprises the steps of: founding a temporary data block flow TBF which is not released before the completion of the business; transmitting data block by the transmitting side with the founded TBF; releasing TBF when the transmission side confirms that the business has complete. The invention avoids the problem that the user feels that the larger service interruption exists caused by the long time to found the TBF by founding the TBF which is not released before the completion of the business. Otherwise, the invention realizes that the power consumption of the MS is not increased when the TBF is not released for a long time to avoid the effect to the capability of the whole GPRS network with that the TBF which is not released before the completion of the business has a preference usufruct and that a TBF sleep and awakening flow path are increased. The present invention also discloses a system for realizing the transmission of the grouping data.

Description

A kind of implementation method of packet data transmission and system

Technical field

The present invention relates to packet data transmission technique, particularly a kind of implementation method of packet data transmission and system.

Background technology

In GPRS (GPRS), carry out before the packet data transmission, Temporary Block Flow (TBF) need be set up earlier,, the transmission of Radio Link control (RLC) data block can be carried out between travelling carriage (MS) and the network by the grouping resources of network allocation.

If MS will as base station sub-system (BSS), send up RLC data block to network side, then at first need to set up a up TBF by grouping access procedure (packet access procedure); If network side will send descending RLC data block to MS, then need to set up earlier descending TBF.

Fig. 1 sets up the flow chart of uplink and downlink TBF for prior art.As shown in Figure 1, the flow process of setting up up TBF comprises the steps:

Step 101, MS goes up to network side at Physical Random Access Channel (PRACH) and sends packet channel request message (PACKET CHANNEL REQUEST), and the request network is self allocation packets resource.

Step 102, after network is received packet channel request message, distribute the resource on one or more packet traffic channels (PDCH) to give MS, and go up to MS at the Packet Access Grant Channel of receiving the Packet Common Control CHannel of packet channel request message (PCCCH) (PAGCH) and to send packet uplink assignment messages (PACKET UPLINK ASSIGNMENT) message, inform that MS is the resource on the packet traffic channel of its distribution.

In the prior art, the foundation of TBF can be used a step access procedure, also can use for two steps inserted (Two phase packet access) process.A so-called step access procedure is meant that after step 102 is finished up TBF just sets up and finishes, and MS can send up RLC data block to network by this up TBF; And two step access procedures are meant after step 102, and before up TBF set up and finishes, MS also needed to send the grouping resources request message to network once more, as step 103 as described in the step 104.

Step 103, MS sends grouping resources request (PACKET RESOURCE REQUEST) to network side on the grouping resources that distributes, the grouping resources that amount of the claim is outer.

The additional packet resource notification MS that step 104, network use the packet uplink assignment messages to distribute as MS.

Step 105, up TBF sets up and finishes, and MS sends up RLC data block to network side.

As shown in Figure 1, the flow process of setting up descending TBF comprises the steps:

Step 106, network side send grouping downlink and assign (PACKET DOWNLINK ASSIGNMENT) message on the PCCCH under the MS, the resource on the downlink grouping traffic channel that will distribute for MS is informed MS.

Step 107, the reservation up-link wireless piece (uplinkradio block) of MS appointment in the grouping downlink assignment messages go up to network example transmission grouping control confirms (PACKET CONTROLACKNOWLEDGEMENT) message, confirms.

Step 108, descending TBF sets up and finishes, and network sends descending RLC data block to MS by this descending TBF.

In GPRS network, the distinguishing feature of TBF is provisional at present, if TBF does not have new transfer of data, then discharges TBF immediately; If have new data to need transmission again, then need to rebulid TBF.Because setting up the time frame of TBF is hundred milliseconds even second level, so the provisional of TBF makes the continuity of Packet Service and user's experience be subjected to very big influence.As: in the packet voice business, when in both sides' communication process, a side does not speak for a long time, makes corresponding TBF not have transfer of data in a period of time, causes TBF to be released, and when this side's user speaks again, need rebulid TBF.Owing to the time of setting up TBF is long, generally need 3 Round Trip Time Measurement (RTT) times, therefore can cause talk business long start-up time, make the user feel that talk business has interruption.

For the continuity and the user experience that can improve Packet Service, agreement has been carried out certain enhancing to TBF at present, even make do not have new transfer of data also not discharge TBF immediately in a period of time, discharges but wait for a period of time again.This Enhancement Method mainly contains two kinds of patterns: descending TBF postpones to discharge (Delayed downlink TBF release) and expansion up TBF pattern (Extended uplinkTBF mode).

Postpone in the release mode at descending TBF, after network sends all downlink data block of preserving in the buffering area, for when new upper layer data (LLC PDU) arrives, can continue to use this descending TBF to carry out descending RLC transfer of data, network does not discharge this descending TBF immediately.At this moment, do not have the descending RLC data block of new user to need transmission, but will keep descending TBF, network need transmit the descending RLC data block that inserts filling information to MS, to keep descending TBF link.Under the A/Gb pattern, can reach the purpose that postpones release by in descending TBF, inserting logical link control layer UI dummy argument instruction (LLC UI Dummy command).If an end that keeps at descending TBF is in the time, when having new upper layer data to send, network stops to send the descending RLC data block that inserts filling information to MS, sends the descending RLC data block of user to MS again.If in a period of time that descending TBF keeps, never having the descending RLC data block of new user needs to send, and then network can discharge this descending TBF.

The method that this delay discharges need be when not having new RLC data block to transmit, transmit some non-user data to guarantee not discharge TBF, influence to MS is very big, the power consumption of MS is increased, therefore, cause too much influence for fear of the overall performance to GPRS network, generally the time that TBF is postponed to discharge is decided to be 5 seconds.

In the up TBF pattern of expansion, carry out the release of up TBF by network control.Network is replied designator (Final Ack Indicator) with the termination in packet uplink affirmation/non-affirmation (the PACKET UPLINK ACK/NACK) message and is set to 1, informs that MS discharges up TBF; MS uses grouping control affirmation (PACKET CONTROL ACKNOWLEDGEMENT) message to reply, and discharges up TBF, and promptly MS does not re-use the resource that network side is this MS distribution, leaves the channel at these resource places.After network was received grouping control acknowledge message, the temporary data block flow identifier (TFI) that this up TBF is shared and uplink state sign (USF) resource can be redistributed to other MS and use.If network is not received this grouping control acknowledge message, then can the up affirmation of packet retransmission/non-acknowledge message, and increase the value of N3101 counter.If the value of N3101 counter reaches predefined maximum, then network will stop to be this up TBF scheduling USF, and starts timer T3169, when the T3169 timer expiry, network is reused TFI and the USF resource that this up TBF takies, and it is distributed to other TBF or MS.

Expand in the up TBF pattern, if up TBF does not have RLC data block to send, then MS need send packet uplink dummy argument controll block (PACKET UPLINK DUMMYCONTROL BLOCK) to network side, to keep up TBF link.

In order to reduce the power consumption of MS as far as possible, reduce the influence that the overall performance to GPRS network causes, existing descending TBF postpones release mode the craticular stage that TBF postpones to discharge is defined as 5 seconds, and inertia also can discharge TBF after the time limit.Like this, after discharging TBF, when having downlink data block to transmit again, still need to rebulid descending TBF.

Above-mentioned descending TBF postpones to discharge and expand up TBF pattern, all need be when not having new RLC data block to transmit, transmit some specific non-user data to guarantee not discharge TBF, such practice can increase the power consumption of MS greatly, and the overall performance of GPRS network is caused very big influence.In order to reduce the power consumption of MS as far as possible, reduce the influence that the overall performance to GPRS network causes, over time, be generally 5 seconds, still can discharge TBF.

Therefore, utilize existing TBF to postpone release mode, can not solve MS power consumption and the problem that influences the GPRS network performance fully, still can't avoid to spend the long time, and make the user feel the professional problem that has bigger interruption owing to set up TBF.

Summary of the invention

Embodiment

For making purpose of the present invention, technical scheme and beneficial effect clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.

The implementation method of packet data transmission of the present invention and system, make before business is finished that the TBF of foundation can not be released by setting up the TBF that does not discharge before business is finished.

The implementation method of packet data transmission of the present invention comprises the steps: the TBF that do not discharge before setting up business finishes; The TBF that does not discharge before the business that the transmit leg utilization is set up is finished sends data block to the recipient; After business is finished, discharge the TBF that does not discharge before this business is finished.The present invention has avoided need spending the long time owing to set up TBF, and has made the user feel to exist the problem of big service disconnection by being based upon the TBF that does not discharge before business is finished.

Below the TBF that do not discharge before business finished abbreviate semipermanent TBF as.

Before setting up semipermanent TBF, MS and network side need mutual notice whether to possess the ability of setting up semipermanent TBF.Network side can increase a cell or flag bit in system message or control signaling, be used for describing the tenability to semipermanent TBF, informs that by system message broadcasting all MS network sides are to the tenability of semipermanent TBF in this sub-district; Or by the tenability of the specific MS network side of control signaled to semipermanent TBF.MS also need increase a cell or flag bit in sending to the signaling of network side, be used for describing tenability, as can in wireless access capability (Radio Access Capability) cell, describing tenability to semipermanent TBF to semipermanent TBF.

If MS and network side are all supported semipermanent TBF, just can between MS and network side, set up semipermanent TBF.MS is setting up TBF and network side when MS sends assignment messages to the network side request, that need indication foundation is semipermanent TBF.In addition, when network side reshuffled, divides into groups switching or double-transmission mode (DTM) handoff procedure in execution, that also need indicate description in the information that sends to MS be semipermanent TBF.

In addition, the present invention distributes by resource being carried out classification, the TBF that does not discharge before identification service is finished has preferential right to the resource of being distributed, and in professional transmission course, increase the TBF sleep and wake flow process up, make after the TBF sleep, can distribute to other user for the resource of its distribution uses temporarily, thereby realized not increasing the power consumption of MS, avoided the performance of whole GPRS network is impacted not discharging under the situation of TBF for a long time.

The classification of resource distributes, referring to network side can be with a grouping resources unit, as channel, time slot or grouping block, use priority assignment to use according to difference to different user, take and take two kinds of different use priority temporarily as being divided into domination, the domination occupancy mode represents that the user has preferential right to the resource of being distributed, and takies the expression user temporarily the resource that is assigned to is had the interim right to use, and network side can be regained these resources at any time.

Fig. 2 is the flow chart of first preferred embodiment of the implementation method of packet data transmission of the present invention.This embodiment utilizes up TBF to carry out the realization flow of packet data transmission, and this flow process comprises the steps:

Step 201, MS sends packet channel request message to network side, and indication is set up up semipermanent TBF, the up TBF that does not discharge before the business that promptly is based upon is finished in this message.

Here, indication is set up up semipermanent TBF and can be carried the indication of setting up up semipermanent TBF by increase a cell or flag bit in packet channel request message in packet channel request message.Can also comprise a cell in the packet channel request message, carry the time span value that is used for the monitoring of TBF quiet period.

Step 202, after network side receives and carries the packet channel request message of setting up up semipermanent TBF indication, distribute the resource on one or more packet traffic channels (PDCH) to give this up semipermanent TBF, and identify this up semipermanent TBF network is had preferential right for the resource of its distribution, and the Packet Access Grant Channel (PAGCH) on the Packet Common Control CHannel of receiving the packet channel request message place (PCCCH) informs that upward to MS transmission packet uplink assignment messages the MS network side is the resource on the packet traffic channel that this up semipermanent TBF distributed.

The up semipermanent TBF of described sign to network side for the resource of its distribution have preferential right can for: network side identifies described up semipermanent TBF to have the highest use priority for the resource of its distribution; Other TBF of described sign or MS to the resource that is assigned to have the interim right to use can for: network side identify other TBF or MS the resource that is assigned to is had different, than the low priority of the highest described use priority.

Each grouped channels resource can be distributed to a plurality of users, and each user's use priority is all inequality.Network side need use the highest user of priority among the user of this grouped channels resource of use with the grouped channels resource allocation to current.

Below for convenience, abbreviate up semipermanent TBF as up TBF.

Step 203, up TBF sets up and finishes, and network begins to be this up TBF scheduling USF that MS monitors USF on the channel that this up TBF distributed, so that send up RLC data block to network side.

Present embodiment adopts the step access procedure of TBF, also can adopt the two step access procedures of TBF, promptly after step 202, send the grouping resources request to network side on the grouping resources that preceding following steps: the MS of increasing of step 203 is its distribution at network side, the request network side is the outer grouping resources of self allocation; Network side is the outer grouping resources of MS allocation, and sign MS is to for the resource of its distribution has preferential right, and the additional packet resource notification MS that uses the packet uplink assignment messages to distribute as MS.

Step 204, network side detects up TBF according to the time span of setting and whether enters quiet period, promptly detect in default time span, whether not receive the new upstream data that this up TBF sends, and when confirming that up TBF enters quiet period, execution in step 205.

Here, the setting of time span can be that network side preestablishes time span, also can be that MS preestablishes time span.Network side can be carried at all MS that are broadcast in the system message in the sub-district with default time span.MS can be carried at default time span in the packet channel request message, sends to network side, and network side is determined time span according to the time span that the MS that receives sets again.

Step 205, network side sends grouping TBF sleep (Packet TBF Sleep) message to MS, carry sign and the sleep reason of TBF in this message, the sign of described TBF can be in the sub-district this up TBF of unique identification, can be packet flow identifier (PFI) or the temporary flow identity symbol (TFI) of this up TBF.

Step 206, MS no longer monitors the USF of network for this TBF scheduling after receiving grouping TBF sleep message, finishes sleep, and returns grouping control acknowledge message to network side, and the sleep flow process is confirmed.

After the up TBF sleep, MS does not re-use this up TBF and sends upstream data to network, and network no longer is this TBF scheduling USF.After up TBF sleep,, then handle according to the mode of present agreement regulation if this MS also has other TBF; If there is not other TBF, then MS can select to leave packet transfer mode (Packet Transfer Mode), forwards on Packet Common Control CHannel (PCCCH) or the Common Control Channel (CCCH).

After described up TBF sleep, network side can be distributed to other user with the resource on the grouped channels that distributes for this TBF temporarily and use, other user can be other TBF or MS, and the user that sign is assigned to these resources has the interim right to use to the resource of being distributed, when the TBF that these resources is had preferential right need reuse these resources, network side can reclaim these resources at any time, gives the described TBF that these resources is had preferential right with resource assignment again.

When MS defines new upstream data and need use the above-mentioned TBF that has slept to be transferred to network side, carry out following steps:

Step 207, MS sends grouping TBF and wakes (Packet TBF Wakeup) message up on PRACH, the PACCH that perhaps utilizes same MS to go up on other TBF sends grouping TBF wakeup message, the sign of carrying this up TBF in this message, and MS recovers to monitor USF on the channel that this TBF distributed simultaneously.

After step 208, network receive grouping TBF wakeup message, for this up TBF carries out the USF scheduling.

If the resource of this up TBF is distributed to other user by network side and used temporarily, then network side need be regained these resources, uses for again this up TBF.

Step 209 when MS listens to the USF of network for its scheduling, then uses this up TBF to send upstream data to network side.

MS can start a timer after sending grouping TBF wakeup message, be used for monitoring and whether receive the USF scheduling.Timer length can be set by MS, as 100 milliseconds.If MS behind timer expiry, does not detect the USF scheduling, then return step 207 again and carry out retry, and restart timer; If repeatedly retry invalid after, behind retry 3 times, then initiate to rebuild up TBF flow process.

Step 210 after business is finished, discharges this up TBF.

Among the described embodiment of Fig. 2, the sleep procedure of up TBF is by network control, and promptly whether the time span detection TBF by network based setting enters quiet period, and after monitoring, sends grouping TBF sleep message to MS; Returning grouping control acknowledge message to network side after MS receives grouping TBF sleep message confirms.

As shown in Figure 3, Fig. 3 is the flow chart of second preferred embodiment of the implementation method of packet data transmission of the present invention, and this process step 301 is consistent to step 203 with the step 201 of flow chart shown in Figure 2 to step 303; Step 307 is consistent with step 210 with step 207 to step 310, and difference only is that the TBF quiet period detects and TBF sleep flow process, shown in step 304 to 306:

Step 304, MS detects up TBF according to default time span and whether enters quiet period, and promptly detect and in default time span, whether do not utilize this up TBF to send up RLC data block to network, and when confirming not send, execution in step 305.

Here, the setting of time span can be that network side is predefined, also can be MS setting-up time length.MS can be carried at the time span of setting in the packet channel request message, sends to network side, and network side is determined time span and notified MS according to the time span that the MS that receives sets again; Network can carry a default time span in system message, be broadcast to all MS in the sub-district, and MS can select to use this value, also can use time span of preceding method request.

Step 305, MS sends grouping TBF sleep (Packet TBF Sleep) message to network side, carry sign and the sleep reason of TBF in this message, the sign of described TBF can be in the sub-district this up TBF of unique identification, can be packet flow identifier (PFI) or the temporary flow identity symbol (TFI) of this up TBF.

After step 306, network side receive grouping TBF sleep message, no longer be this TBF scheduling USF, and return grouping control acknowledge message, the sleep flow process is confirmed to MS.

After MS receives acknowledge message, leave all channels that this TBF distributes, no longer monitor USF, finish sleep.If this MS also has other TBF, then handle according to the mode of present agreement regulation; If there is not other TBF, then forward on Packet Common Control CHannel (PCCCH) or the Common Control Channel (CCCH).

Here, the sleep procedure of semipermanent TBF is initiated by MS, promptly detects TBF by MS according to the time span of setting and whether enters quiet period, and after monitoring, send grouping TBF sleep message to network side; After receiving grouping TBF sleep message, network side returns grouping control acknowledge message to MS.

Fig. 4 is the flow chart of the 3rd preferred embodiment of the implementation method of packet data transmission of the present invention.This embodiment utilizes descending TBF to carry out the realization flow of packet data transmission, and this flow process comprises the steps:

Step 401, network side is the resource on the descending TBF allocation of downlink packet traffic channel that will set up, identify this descending TBF these resources are had preferential right, and will be carried in the grouping downlink assignment messages for the resource on the downlink grouping traffic channel of this descending TBF distribution, send to the affiliated MS of this descending TBF, and that indication is set up is descending semipermanent TBF, the descending TBF that does not discharge before promptly professional the finishing.

The descending TBF of described sign to network side for the resource of its distribution have preferential right can for: network side identifies described descending TBF to have the highest use priority for the resource of its distribution; Other TBF of described sign or MS to the resource that is assigned to have the interim right to use can for: network side identify other TBF or MS the resource that is assigned to is had different, than the low priority of the highest described use priority.

Below for convenience, abbreviate descending semipermanent TBF as descending TBF.

Can also comprise a cell in the grouping downlink assignment messages, carry the time span value that is used for the quiet period monitoring.

Network side can pass through on the PCCCH or CCCH at this MS place, or on the PACCH channel of this other TBF of MS, the grouping downlink assignment messages is sent to MS.

Step 402, the reservation up-link wireless piece (uplinkradio block) of MS appointment in the grouping downlink assignment messages go up to network side and send grouping control affirmation (PACKET CONTROLACKNOWLEDGEMENT) message, confirm.

Step 403, descending TBF sets up and finishes, and network sends descending RLC data block to MS.

Step 404, network side detects descending TBF according to the time span of setting and whether enters quiet period, promptly detects in default time span, whether does not send new descending RLC data block, and when confirming that descending TBF enters quiet period, execution in step 405.

Here, the setting of time span can be that network side is predefined, also can be MS setting-up time length.Network can use a default time span, and carries all MS that are broadcast in the sub-district in system message; MS can be carried at the time span of a setting in the packet channel request message, sends to network side, and network side is determined time span according to the time span that the MS that receives sets again.

Step 405, network side sends grouping TBF sleep (Packet TBF Sleep) message to MS, carry descriptor and the sleep reason of descending TBF in this message, the descriptor of described descending TBF can be packet flow identifier (PFI) or the temporary flow identity symbol (TFI) of this descending TBF at sub-district, MS place this descending TBF of unique identification.

Step 406, MS returns grouping control acknowledge message to network side after receiving grouping TBF sleep message, the sleep flow process is confirmed, and left all channels that this descending TBF distributes.

If this MS also has other descending TBF, handle according to the mode of present agreement regulation; If there is not other descending TBF, then forward on Packet Common Control CHannel (PCCCH) or the Common Control Channel (CCCH).

After descending TBF sleep, network side does not re-use this descending TBF and sends data.Network side can be distributed to other user with the resource of distributing for this descending TBF temporarily and use, and identify other user these resources are only had the interim right to use, need use these resources in case these resources are had the descending TBF of preferential right, network side can reclaim these resources at any time and be assigned to the described descending TBF that these resources is had preferential right again.The user here can be MS or TBF.If this descending TBF place MS does not have movable in addition TBF, MS can select to leave packet transfer mode.

When network side has new downlink data need use the above-mentioned descending TBF that has slept to be transferred to MS, carry out following steps:

Step 407, network side send grouping TBF wakeup message to MS on the PCCCH at the MS place that has this descending TBF or CCCH;

The PACCH that perhaps utilizes same MS to go up on other TBF sends grouping TBF wakeup message to MS;

Perhaps have the downstream assigned message (Packet DownlinkAssignment) of waking sign up, assign this descending TBF again to the MS transmission,

Carry the identification information of this descending TBF in above-mentioned grouping TBF wakeup message or the downstream assigned message.

After sending grouping TBF wakeup message or downstream assigned message, whether network side is used for monitoring and wakes up successful for this TBF starts a timer.Timer length is determined by network, is generally 100ms.

Step 408, network side send descending RLC data block to MS after one very short period, and in this data block RRBP are set, and require MS echo reply message.

If timer expiry, and do not receive and reply, this descending TBF then rebuild.

Step 409, after MS receives described TBF wakeup message or carries the downstream assigned message of TBF wakeup message, MS gets back to network side at once on the Traffic Channel that this descending TBF distributed, prepare to receive data, after receiving first RLC downlink data block, reply grouping downlink affirmation/non-acknowledge message according to RRBP to network side, inform that this descending TBF of network side recovers successfully.

Here, also can in the grouping TBF wakeup message that MS sends, RRBP be set, require MS to return acknowledge message at step 407 network side;

After MS receives the grouping TBF wakeup message that is provided with RRBP, return grouping downlink affirmation/non-acknowledge message, inform that this descending TBF of network recovers successfully to network side;

Network side stops described timer, and thinks and wake success up after receiving the grouping downlink affirmation/non-acknowledge message that MS returns, and utilizes described descending TBF to send descending RLC data block to MS.

Step 410 after business is finished, discharges this descending TBF.

Among the described embodiment of Fig. 4, the sleep procedure of descending TBF is by network control, promptly detects descending TBF by the time span of network based setting and whether enters quiet period, and after affirmation, send grouping TBF sleep message to MS; After receiving grouping TBF sleep message, MS returns grouping control acknowledge message to network side.Here, the sleep procedure of descending TBF also can be initiated by MS, promptly detects descending TBF by MS according to the time span of setting and whether enters quiet period, and after affirmation, send grouping TBF sleep message to network side; After receiving grouping TBF sleep message, network side returns grouping control acknowledge message to MS.

As shown in Figure 5, be the flow chart of the 4th preferred embodiment of the implementation method of packet data transmission of the present invention, it is consistent that this process step 501 arrives step 403 to the step 503 and the step 401 of flow chart shown in Figure 4; Step 507 is consistent with step 410 with step 407 to step 510, and difference only is that the TBF quiet period detects and TBF sleep flow process, shown in step 504 to 506:

Step 504, MS detects descending TBF according to default time span and whether enters quiet period, promptly detects in default time span, whether not receive the new descending RLC data block that this descending TBF sends, and when confirming not receive, execution in step 505.

Step 505, MS sends grouping TBF sleep (Packet TBF Sleep) message to network side, carry descriptor and the sleep reason of TBF in this message, the description of described TBF can be packet flow identifier (PFI) or the temporary flow identity symbol (TFI) of TBF at sub-district, MS place this up TBF of unique identification.

Step 506, network side are returned grouping control acknowledge message to MS after receiving grouping TBF sleep message, and the sleep flow process is confirmed.After MS receives acknowledge message, leave all channels that this TBF distributes, finish sleep.If this MS also has other TBF, handle according to the mode of present agreement regulation; If there is not other TBF, then forward on Packet Common Control CHannel (PCCCH) or the Common Control Channel (CCCH).

Fig. 2 discharges among the TBF identification service and has finished two kinds of situations in flow process shown in Figure 5 after business is finished:

Whether finish by whether finishing PDP context deactivation process (PDP Context DeactivationProcedure) identification service; Or whether finish deletion packet flow context process (Delete PFC Procedure) identification service by network side and whether finish.

For the release of up TBF, refer to MS and no longer monitor USF and use the channel of this TBF to be used for transmitting uplink data, network no longer is its scheduling USF, the TFI and the USF that distribute to this TBF use for other users; For the release of descending TBF, refer to the channel that MS no longer monitors this TBF, network does not re-use the channel user downlink data transmission of this TBF, and the TFI that distributes to this TBF uses for other users.

For by whether finishing the situation that PDP context deactivation process identifier business is finished, the flow process that discharges TBF in two kinds of situation: if the PDP context deactivation process is initiated by MS, then the release of TBF is triggered by MS, flow process as shown in Figure 6:

Step 601, MS initiates the PDP context deactivation process, after deactivation process is finished, execution in step 602.

Step 602, MS sends to network side and discharges the TBF request, and request discharges TBF.Carry the TFI of correspondence of TBF or PFI, release cause in this request, and require network answer.

Step 603, network side discharge corresponding TBF according to the information of wherein carrying after receiving the TBF release request of MS transmission.

Step 604, network side confirms to discharge TBF by grouping control acknowledge message to MS.

Step 605, MS receives the grouping control acknowledge message that network side sends, and discharges TBF.

More reliable for the release flow process that makes TBF, after MS sends release TBF message, start a timer simultaneously, timer length can be determined voluntarily by MS, be generally 100ms.If receive the grouping control acknowledge message of confirming that TBF discharges before this timer expiry, then this timer stops timing, and MS discharges this TBF; If this timer expiry and do not receive the grouping control acknowledge message of confirming that TBF discharges, then MS needs to send grouping TBF release message to network again, restart this timer, reclocking.If after the MS retry preset times, as 3 times, do not receive the grouping control acknowledge message that affirmation TBF that network side sends discharges yet, then retry no longer discharges this TBF simultaneously.

If the PDP context deactivation process is initiated by network side, then the release of TBF is triggered by network side, flow process as shown in Figure 7:

Step 701, network side is initiated the PDP context deactivation process, after deactivation process is finished, execution in step 702.

Step 702, network side send to MS and discharge the TBF request, and request discharges TBF.Carry the TFI of TBF correspondence or PFI, release cause in this request, and require MS echo reply message.

Step 703, MS discharges corresponding TBF according to the information of wherein carrying after receiving the TBF release request of network side transmission.

Step 704, MS discharges corresponding TBF by grouping control acknowledge message to network validation.

Step 705, network side discharge corresponding TBF after receiving the grouping control acknowledge message of MS transmission.

For whether finished the situation whether PFC delete procedure identification service is finished by network side, the flow process that discharges TBF is triggered by network side, and as shown in Figure 8, this flow process comprises the steps:

Step 801, network side are carried out deletion PFC process, after confirming that deletion PFC finishes, and execution in step 802.

Step 802, network side determine whether this PFC has corresponding TBF to exist, if any, execution in step 803.

Step 803, network side send to MS and discharge the TBF request, and request discharges TBF.Carry the TFI of TBF correspondence or PFI, release cause in this request, and require the MS response message.

Step 804, MS discharges corresponding TBF after receiving this release TBF message.

Step 805, MS returns grouping control acknowledge message to network side the TBF release message is replied, and confirms to discharge corresponding TBF.

Step 806, network side discharge corresponding TBF after receiving the grouping control acknowledge message of MS transmission.

Fig. 7 and TBF shown in Figure 8 discharge in the flow process, after network side sends release TBF message, can start a timer Timer1 simultaneously, and timer length can be determined voluntarily by network side, be generally 100ms.Before if Timer1 is overtime, network side receives that TBF discharges the affirmation message of finishing, and then stops timer Timer1, discharges this TBF.Do not receive that before timer expiry TBF discharges the affirmation message of finishing, can repeating step 803.

If timer Timer1 is overtime, and network side do not receive that TBF discharges the affirmation message finish, and then network side discharges this TBF.Network side also needs to restart another one timer Timer2 simultaneously, and Timer2 length is generally 200ms, and after Timer2 was overtime, network side just can be distributed to other TBF use with the TFI and the USF of this TBF correspondence.

Network side of the present invention can be base station sub-system (BSS).
