Description
Technical field
The present invention relates to moving communicating field, particularly the technology of setting up of Temporary Block Flow.
Background technology
GPRS (General Packet Radio Service is called for short " GPRS ") network is the network that is used to provide the packet data exchanged business that grows up on existing GSM network foundation.
The GPRS network agreement is made up of transport plane and signaling plane.Transport plane provides the transmission and the relevant control procedure of user profile, as the message transmission of processes such as Flow Control, error detection, error correcting and wrong recovery; Signaling plane provides the control of transport plane and support, finishes the association of control that GPRS network insert to connect, packet data protocol and supplementary service etc.
In the protocol stack of GPRS, the sublayer that has two transfer of data, logical link control layer agreement (Logic Link Control Layer is called for short " LLC ") sublayer and wireless chain control layer agreement (RadioLink Control Layer is called for short " RLC ") sublayer.
In GPRS, the RLC between portable terminal and the network connects and is called Temporary Block Flow (TemporaryBlock Flow is called for short " TBF ").TBF is in order to support the transmitted in both directions of grouped data on PDCH (grouping physical channel).Single TBF is always unidirectional, and it can be divided into up TBF and descending TBF, is that up TBF or descending TBF only exist during RLC connects.
In order to guarantee the reliability of RLC data in the transmission course, the TBF of RLC sublayer can select the automatic repetitive requests of a kind of RLC (RLC ARQ) to transmit.The TBF of RLC sublayer supports three kinds of automatic repetitive requests operator schemes of RLC at present: RLC affirmation mode (RLC acknowledged mode), RLC Unacknowledged Mode (RLC unacknowledged mode) and RLC non-persistent mode (RLCnon-persistent mode).At same direction, synchronization, same TBF can only use a kind of RLC pattern to carry out transfer of data.The characteristics of these three kinds of ARQ are:
1, the RLC affirmation mode does not have the correct RLC data block that receives can both correctly to be received to guarantee each data block by retransmitting each, and RLC guarantees LLC-PDU (protocol Data Unit, ProtocolData Unit are called for short " PDU ") is transferred to peer layer;
2, the RLC Unacknowledged Mode does not carry out the repeating transmission of RLC data block, and RLC does not guarantee LLC-PDU is transferred to peer layer reliably;
3, the RLC non-persistent mode uses non-retransmit fully (non-exhaustiveretransmission) of RLC data block, and some pieces that do not have correctly to receive may be not retransmitted, and RLC partly guarantees LLC-PDU is transferred to peer layer reliably.
In order to realize session service, support low time delay business, TBF generally adopts the RLC non-persistent mode to carry out packet data transmission.
In the prior art, portable terminal will send grouped data to network, at first will set up up TBF.The up TBF of typical R-L-C non-persistent mode to set up process as follows:
In step 110, portable terminal is to network transmitting channel resource request (PACKETRESOURCE REQUEST), up TBF is set up in requirement, carries wireless access capability (Radio Access Capability) cell in this message, tells whether network mobile terminal supports non-persistent mode;
Then entering step 120, after network is received request, after the tenability of acquisition portable terminal to non-persistent mode, is the TBF that this portable terminal distributes non-persistent mode, sends resource allocation to it.
Then enter step 130, portable terminal begins to send uplink data block on the non-persistent mode TBF that distributes.
RLC non-persistent mode TBF is generally at Enhanced Data rates for GSM Evolution (EDGE, EnhancedData rates for GSM Evolution) uses in, network is being described EGPRS TBF in the message for setting up of portable terminal distribution T BF, tells whether portable terminal has set up a non-persistent mode TBF.
The description to EGPRS TBF mainly comprises following content in the agreement at present:
1, RLC pattern (RLC_MODE) is described the employed RLC pattern of current TBF, uses 1 bit to represent;
2, window size (EGPRS Window Size) is described the window size of current TBF, generally uses 5 bits to represent;
3, temporary flow identity symbol (TFI) is used for identifying this TBF;
4, packet flow identifier (PFI) is used for identifying a packet flow context (Packet Flow Context) that is associated with TFI;
5, channel resource is described the radio channel resource of distributing to current TBF.
For portable terminal and the network of supporting non-persistent mode, judge the ARQ pattern (ARQ determination methods one) of current TBF by the RLC_MODE in the TBF descriptor and two cells of EGPRS Window Size:
1, RLC_MODE is 0, is affirmation mode;
2, RLC_MODE be 1 and EGPRS Window Size zero the time, be Unacknowledged Mode for complete;
3, RLC_MODE be 1 and EGPRS Window Size zero the time, be not non-persistent mode for complete.
And for the network of not supporting non-persistent mode TBF and portable terminal, it only decides TBF ARQ pattern (ARQ determination methods two) according to RLC_MODE:
1, RLC_MODE is 0, is affirmation mode;
2, RLC_MODE is 1, is Unacknowledged Mode.
Above-described method is to adopt when network is portable terminal distribution T BF.Network is that the scene of portable terminal distribution T BF comprises that TBF assigns process, handoff procedure, and other distribution or reshuffle the flow process of TBF.
As shown in Figure 1, for a sub-district of not supporting non-persistent mode, assign three identical TBF for respectively two different portable terminals, wherein NPM (non-persistent mode, Non-Persistent Mode) is supported in portable terminal _ 1, and NPM is not supported in portable terminal _ 2.The appointment content that issues shown in the form of top among the figure, two portable terminals to the understanding of this message respectively shown in below form among the figure.With regard to TBF_1, network-assigned be Unacknowledged Mode, support portable terminal _ 1 of NPM then it to be misinterpreted as non-persistent mode.
As seen, the present method of salary distribution can make the portable terminal of supporting NPM and not support and produce assigning understanding differently of content to cause between the network of NPM, the processing mode that makes portable terminal and BSS adopt in data transmission procedure is different, thereby make follow-up operation bigger problem occur, cause link undesired.If that network is given portable terminal _ 1 distribution is the up TBF of a Unacknowledged Mode, and the TBF of a non-persistent mode is thought in portable terminal _ 1, will retransmit the data block of not receiving confirmation of receipt in the send window, promptly be designated the data block of (PENDING_ACK); For descending TBF, portable terminal _ 1 can be according to the incorrect piece that receives in the non-persistent mode feedback receive window.These abnormal problems have all increased the power consumption of mobile phone, have influenced the performance of GPRS network.
The main cause that above-mentioned situation occurs, be that portable terminal does not know whether the TBF of network allocation has used NPM, cause the ignorant this situation of portable terminal, mainly be because network is not informed its support situation to non-persistent mode TBF of portable terminal, and network does not inform clearly whether the current TBF that assigns of portable terminal uses non-persistent mode TBF.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is: network is by the message informing portable terminal, makes portable terminal know network is whether the TBF of its distribution has used NPM.Specifically can be, network is by informing its tenability to non-persistent mode TBF of message informing portable terminal, perhaps when setting up TBF, tell clearly that portable terminal is current and whether use non-persistent mode by setting up message, perhaps adopt and inform message and set up the mode that message cooperates for its distribution T BF.Avoid because network is not informed its support situation to non-persistent mode TBF of portable terminal with this, and network do not inform clearly whether the current TBF that sets up of portable terminal uses non-persistent mode, makes when BSS sets up TBF portable terminal with BSS same TBF be described and has different understanding.
Among the present invention, network increases non-persistent mode sign (NPM_USED or NPM_SPT) in the message that sends for portable terminal.The network of having introduced non-persistent mode TBF is called new network, uses the non-persistent mode sign in this network.New network can be supported non-persistent mode TBF, also can not support non-persistent mode TBF, identify by NPM_SPT and represent, and the TBF pattern indication when specifically setting up identifies by NPM_USED; Do not introduce the network of non-persistent mode TBF (yet not using NPM_USED), be called the existing network network.These two kinds of networks are referred to as network.Among the present invention,, the portable terminal of not supporting non-persistent mode TBF is called existing portable terminal with supporting the portable terminal of non-persistent mode TBF to be called new portable terminal.
The present invention program totally comprises two parts: network is informed portable terminal and portable terminal judges according to informing of network.
At first, network can be as follows to the informing method of portable terminal:
1, new its tenability of network notice portable terminal to non-persistent mode TBF
New network is by informing message, informs that all mobile terminal networks under the current area are to the support situation of non-persistent mode TBF; Support under the non-persistent mode TBF situation at portable terminal, inform that message can be system message or control signaling, do not support under the non-persistent mode TBF situation, inform that message can be system message at portable terminal.
In above-mentioned situation, new network comes the explicit portable terminal current network of informing whether to support non-persistent mode TBF by increase RLC non-persistent mode support sign (NPM_SPT) in message, and portable terminal judges according to this sign whether network supports NPM TBF.NPM_SPT can use a plurality of bits to represent, full null representation does not support that other express support for dissimilar non-persistent modes.Can use a bit to represent, 0 expression does not support that 1 expresses support for yet.
2, new network is for setting up of portable terminal distribution T BF provides the mode of whether using non-persistent mode TBF in the message, and comprising appointment, reshuffling with the switch instances lower network is the description of portable terminal distribution T BF.
1) assigns, reshuffle under the situation, comprise, the appointment of descending TBF or reconfiguration message are assigned (PACKET UPLINK ASSIGNMENT) message as packet uplink, the up appointment of many TBF (MULTIPLE TBF UPLINK ASSIGNMENT) message, grouping downlink is assigned (PACKETDOWNLINK ASSIGNMENT) message, many TBF downstream assigned (MULTIPLE TBFDOWNLINK ASSIGNMENT) message, the grouping time slot is reshuffled (PACKET TIMESLOTRECONFIGURE) message, many TBF time slot is reshuffled (MULTIPLE TBF TIMESLOTRECONFIGURE) message, immediate assignment (IMMEDIATE ASSIGNMENT) message, DTM assigns order (DTM ASSIGNMENT COMMAND) message, grouping CS discharges indication (PACKET CS RELEASE INDICATION) message;
2) under the switch instances, comprise grouping switching command (PS HANDOVER COMMAND) message, DTM switching command (DTM HANDOVER COMMAND) message.
Whether in above-mentioned situation, new network uses sign (NPM_USED) by increasing by a RLC non-persistent mode in the message, in conjunction with the determination methods of prior art, come the explicit TBF of portable terminal Current Delegations that informs to use the non-persistent mode mode to distribute.It can be description to single TBF that the non-persistent mode that increases uses sign, also can be to setting up the description of a plurality of or whole TBF in the message.NPM_USED can use a plurality of bits to represent, full null representation does not support that other express support for dissimilar non-persistent modes.Can use a bit to represent, 0 expression does not support that 1 expresses support for yet.
Portable terminal judges informing of network: portable terminal need be distinguished the message of informing that network sends, judge whether network supports non-persistent mode TBF, and network for portable terminal distribution T BF set up whether assigned non-persistent mode TBF in the message.Concrete judgement is as follows:
1) supports the portable terminal of non-persistent mode to attempt obtaining the non-persistent mode support sign of informing in the message, whether support non-persistent mode TBF to judge network.If the existing network network is not with this sign, then can not obtain, think that network do not support non-persistent mode TBF; If get access to NPM_SPT, if the NPM_SPT non-full zero, then think support, otherwise think and do not support.And the portable terminal of not supporting non-persistent mode does not attempt obtaining this sign.When network was not supported NPM TBF, portable terminal judged that network is specially for the method for the TBF pattern of its foundation: ARQ determination methods two; During network support NPM TBF, portable terminal judges that network is specially for the method for the TBF pattern of its foundation: ARQ determination methods one.
2) support that at portable terminal under the situation of non-persistent mode, portable terminal attempts obtaining the NPM_USED that sets up in the message, with judge network be its distribution T BF set up whether assigned non-persistent mode TBF in the message.If do not obtain (the existing network network that does not promptly use this sign), think and do not use non-persistent mode TBF, distinguish the TBF pattern according to " ARQ determination methods two "; If get access to, distinguish the TBF pattern according to following " ARQ determination methods three ".And the portable terminal of not supporting non-persistent mode does not attempt obtaining this sign.
Wherein, when new network is the message of setting up that portable terminal sends distribution T BF, portable terminal judges by this NPM_USED sign of setting up in the message whether network has assigned non-persistent mode TBF, and determination methods is " ARQ judges ten thousand methods three ":
1, NPM_USED is complete zero, judges the TBF pattern according to " ARQ determination methods two " in the prior art;
2, NPM_USED is a non-full zero, is non-persistent mode.
As a kind of possibility, also can adopt following determination methods:
If NPM_USED is complete zero, judge the TBF pattern according to " ARQ determination methods two ";
If NPM_USED is a non-full zero, when RLC_MODE=0, be affirmation mode; When RLC_MODE=1, be non-persistent mode.
By said method, network and portable terminal are just understood the description of TBF conveniently, clearly mutually, have avoided taking place the situation of different understanding.
According to inventive principle, in conjunction with the accompanying drawings, first embodiment of the invention TBF method for building up is described below.In the present embodiment, support the portable terminal of NPM to be linked into the network of not supporting NPM, setting up process with up TBF is example, and network is told clearly by assignment messages that portable terminal is current and whether used non-persistent mode for its distribution T BF.Step is as shown in Figure 2:
201, portable terminal sends the grouped channels resource request to network, requires to set up up TBF, carries wireless access capability (Radio Access Capability) cell in this message;
In this step, because of portable terminal and do not know whether network supports NPM TBF, so in the wireless access capability cell that portable terminal carries in request message, NPM TBF is supported in indication.
202, after network receives the grouped channels resource request of up TBF,, be that portable terminal is assigned one or more up TBF by assignment messages according to self-ability;
203, after portable terminal is received this assignment messages, trial removes to obtain NPM_USED, if do not get access to, distinguishes each TBF pattern according to " ARQ determination methods two ", if get access to, distinguish each TBF pattern according to " ARQ determination methods three ";
In this step, not getting access to the situation of NPM_USED, may be that network is the existing network network, though may be new network also, carry NPM_USED in the assignment messages of new network.If get access to, NPM_USED is complete zero, judges according to " ARQ determination methods three " to get final product.
As a kind of possibility, this step also can adopt following determination methods: if do not get access to, judge according to " ARQ determination methods two ", if get access to NPM_USED for complete zero, judge the TBF pattern according to " ARQ determination methods two " in the prior art; If NPM_USED is a non-full zero, when RLC_MODE=0, be affirmation mode; When RLC_MODE=1, be non-persistent mode.In the present embodiment, if get access to, then NPM_USED is complete zero.
204, after portable terminal is judged the pattern of all TBF in the assignment messages,, begin on the grouped channels that up TBF distributes, to send uplink data block according to the scheduling of network according to the pattern of TBF separately.
Because by said method, network is told clearly by assignment messages that portable terminal is current and whether is used non-persistent mode for its distribution T BF, the misunderstanding of having avoided network and portable terminal may occur the TBF pattern.
Below second embodiment of the invention TBF method for building up is described.In the present embodiment, support the portable terminal of NPM to be linked into the network of not supporting NPM, situation with switching is an example, created one or more TBF between portable terminal and source BSS and be used for transfer of data, owing to reasons such as link-quality problem, NLB need switch to another one BSS (target BS S).In handoff procedure, network sends to portable terminal by switching command with the TBF that objective network distributes, and portable terminal judges currently whether use non-persistent mode for the TBF of its distribution according to the TBF descriptor in the switching command.Step is as shown in Figure 3:
301, at handoff preparation phase (Handover Preparation Phase), source BSS sends grouping and switches requirement (PS Handover Required) message to SGSN, whether the wireless access capability cell that comprises portable terminal in the message, this cell not indicating mobile terminal support NPM TBF.SGSN is transmitted to target BS S by grouping handoff request (PS Handover Request) message with the wireless access capability cell of portable terminal.Target BS S is that portable terminal has distributed one or more TBF, by grouping Handover Request Acknowledge (PS Handover Request Acknowledge) message informing SGSN, carries NPM_USED in the message and is complete zero;
Perhaps:
At handoff preparation phase (Handover Preparation Phase), source BSS sends grouping and switches requirement (PS Handover Required) message to SGSN, the wireless access capability cell that comprises portable terminal in the message, indicating mobile terminal is supported NPM TBF in this cell.SGSN is transmitted to target BS S by grouping handoff request (PS Handover Request) message with the wireless access capability cell of portable terminal.Target BS S is not owing to support NPM TBF, ignore the tenability of portable terminal to NPM TBF, for portable terminal has distributed one or more TBF,, do not carry NPM_USED in the message by grouping Handover Request Acknowledge (PS HandoverRequest Acknowledge) message informing SGSN;
302, at handover execution stage (Handover Execution Phase), it is that the TBF that portable terminal distributed describes to source BSS that SGSN switches confirmation request (PS Handover Required Acknowledge) forwards target BS S by grouping;
303, source BSS sends grouping switching command (PS Handover Command) and gives portable terminal, order this portable terminal to switch to Target cell, source BSS carries or does not carry NPM_USED according to the ability of grouping switching confirmation request message and portable terminal in the grouping switching command;
304, after portable terminal is received the grouping switching command, attempt obtaining NPM_USED,, distinguish each TBF pattern according to " ARQ determination methods three " if get access to NPM_USED; If no, distinguish each TBF pattern according to " ARQ determination methods two ";
305, portable terminal begins to send uplink data block according to the pattern of TBF separately on the grouped channels that up TBF distributes, downlink data receiving on the channel that descending TBF distributes.
Below third embodiment of the invention TBF method for building up is described.In the present embodiment, supporting the portable terminal of NPM to be linked into the network of not supporting NPM, is example with the process of reshuffling, and network is told clearly by reconfiguration message that portable terminal is current and whether used non-persistent mode for its distribution T BF.Step is as shown in Figure 4:
401, network is reshuffled the TBF that portable terminal distributed, by reconfiguration message notice portable terminal;
In this step,, can carry NPM_USED in the reconfiguration message and be complete zero sign for new network; If the existing network network does not then use this sign.Reconfiguration message also can not carried NPM_USED.
402, after portable terminal is received reconfiguration message, attempt removing to obtain NPM_USED and judging the TBF pattern;
In this step,, judge the pattern of each TBF,, judge the pattern of each TBF according to " ARQ determination methods three " if get access to according to " ARQ determination methods two " if do not get access to.
403, portable terminal is according to the pattern of TBF separately, and beginning sends uplink data block on the grouped channels that up TBF distributes, downlink data receiving on the channel that descending TBF distributes.
Because by said method, network is told clearly by reconfiguration message that portable terminal is current and whether is used non-persistent mode for its distribution T BF, the misunderstanding of having avoided network and portable terminal may occur the TBF pattern.
Because network has increased NPM_USED in the description of distribution T BF, therefore need make amendment to the processing mode of existing portable terminal and network, avoid supporting or not supporting the portable terminal of NPM TBF to the mistake in the description appearance processing of TBF.Following two kinds of scenes are made description with embodiment.
Embodiment four, and the portable terminal of not supporting NPM is linked into the network of supporting NPM, and setting up process with up TBF is example, step as shown in Figure 5:
501, portable terminal sends the grouped channels resource request to network, requires to set up up TBF, carries wireless access capability (Radio Access Capability) cell in this message;
In this step, because of portable terminal is not supported NPM, thus though portable terminal has carried the wireless access capability cell in request message, do not indicate whether to support NPM TBF, and directly one or more TBF are set up in request.
502, after network receives the grouped channels resource request of up TBF,, be that portable terminal is assigned up TBF by the packet uplink assignment messages according to self-ability;
503, after portable terminal is received assignment messages, distinguish the TBF pattern according to " ARQ determination methods two ";
In this step, because of portable terminal is not supported NPM, thus do not attempt obtaining NPM_USED in the assignment messages, and directly judge the pattern of each TBF according to " ARQ determination methods two ".
504, portable terminal begins to send uplink data block on the grouped channels that up TBF distributes according to network scheduling.
Embodiment five, and the portable terminal of supporting NPM is linked into the network of supporting NPM, and setting up process with up TBF is example, step as shown in Figure 6:
601, portable terminal sends the grouped channels resource request to network, requires to set up up TBF, carries wireless access capability (Radio Access Capability) cell in this message, and NPM TBF is supported in this cell indication, and one or more TBF are set up in request;
602, after network receives the grouped channels resource request of up TBF,, be portable terminal distribution T BF according to self-ability and NPM_USED value, and by packet uplink assignment messages notice portable terminal;
In this step, NPM is supported in the portable terminal indication, and then network can distribute NPMTBF for portable terminal, also can not distribute NPM TBF.If distributed NPM TBF, having NPM_USED in assignment messages is non-full zero; If do not distribute, have NPM_USED for complete zero, or do not carry NPM_USED.
603, after portable terminal is received assignment messages, attempt going to obtain NPM_USED;
In this step,, then distinguish the pattern of each TBF according to " ARQ determination methods three " if get access to NPM_USED; If do not get access to NPM_USED, then distinguish the pattern of each TBF according to " ARQ determination methods two ".
In this step, not getting access to the situation of NPM_USED, may be not carry the NPM_USED sign in the assignment messages that sends of new network.
604, portable terminal begins to send uplink data block on the grouped channels that up TBF distributes according to the scheduling of network.
To above embodiment four and five, comprise appointment equally, reshuffle and situation such as switching, with the relation object of embodiment one to three seemingly, also repeat no more herein.
In addition, if do not support the portable terminal of NPM to be linked into the network of not supporting NPM, directly judge to get final product according to " ARQ determination methods two " in the prior art.Portable terminal does not attempt obtaining the NPM_SPT that informs in the message, sends the grouped channels resource request at portable terminal to network, requires to set up up TBF, does not indicate whether to support NPM TBF.Network based grouped channels resource request is that portable terminal distributes one or more TBF, sets up the message informing portable terminal by packet uplink.If new network informs that not carrying NPM_SPT in the message identifies, in setting up message, do not carry the NPM_USED sign and be used to indicate whether to use NPM TBF.If the existing network network does not then use sign.Portable terminal does not attempt obtaining this sign.Portable terminal is distinguished the pattern of setting up each TBF in the message according to " ARQ determination methods two ", and portable terminal begins to send uplink data block on the grouped channels that up TBF distributes according to the scheduling of network then.
Network also can be by informing its tenability to non-persistent mode TBF of message informing portable terminal.If portable terminal is supported NPM TBF, then attempt obtaining the NPM_SPT:NPM_SPT that informs in the message for complete zero the time, network is not supported NPM TBF, judges that network is specially for the method for the TBF pattern of its foundation: " ARQ determination methods two "; When NPM_SPT was non-full zero, network support NPMTBF, portable terminal judged that network is specially for the method for the TBF pattern of its foundation: " ARQ determination methods one ".
Below embodiment six is described.Be linked into the network of supporting NPM for the portable terminal of supporting NPM, setting up process with up TBF is example, step as shown in Figure 7:
701, new network sends the system message of carrying NPM_SPT, and NPM_SPT is a non-full zero;
702, portable terminal attempts obtaining the NPM_SPT in the system message, and getting access to NPM_SPT is non-full zero, then thinks network support NPM TBF;
703, portable terminal sends the grouped channels resource request to network, requires to set up up TBF, carries wireless access capability (Radio Access Capability) cell in this message;
In this step, because of portable terminal has been learnt network support NPM TBF, so portable terminal indicates whether to support NPM TBF in the wireless access capability cell.
704, after network receives the grouped channels resource request of up TBF,, be that portable terminal is assigned one or more up TBF by assignment messages according to self-ability;
705, after portable terminal is received this assignment messages,, distinguish each TBF pattern according to " ARQ determination methods one ":, be affirmation mode when RLC_MODE is 0 because the portable terminal known network is supported NPMTBF; When RLC_MODE be 1 and EGPRS Window Size zero the time, be Unacknowledged Mode for complete; When RLC_MODE be 1 and EGPRS Window Size zero the time, be not non-persistent mode for complete;
706, after portable terminal is judged the pattern of all TBF in the assignment messages,, begin on the grouped channels that up TBF distributes, to send uplink data block according to the scheduling of network according to the pattern of TBF separately.
Under this scene, system message is carried the function of NPM_SPT, also can be finished by the control signaling.
Because by said method, network is told clearly by system message that portable terminal is current and whether is used non-persistent mode for its distribution T BF, the misunderstanding of having avoided network and portable terminal may occur the TBF pattern.
In actual scene, carried NPM_SPT though inform message, may be owing to the new reasons such as sub-district, switching that insert, portable terminal can successfully not obtain this sign, can be by informing message and setting up the technical solution that message cooperates.In the case, then set up whether contain the TBF pattern of NPM_USED sign judgement network for its foundation in the message according to the TBF that obtains, method is specially:
Do not get access to NPM_USED, use " ARQ determination methods two "; Get access to NPM_USED, use " ARQ determination methods three ".
Can adopt the another kind of informing message and setting up the message coordinated scheme again, no matter whether obtain NPM_SPT, all attempt obtaining the NPM_USED that sets up in the message, and with the NPM_USED judgement that is as the criterion: do not get access to NPM_USED, use " ARQ determination methods two "; Get access to NPM_USED, use " ARQ determination methods three ".
Below embodiment seven is described.Be linked into the network of not supporting NPM for the portable terminal of supporting NPM, setting up process with up TBF is example, step as shown in Figure 8:
801, new network sends the system message of carrying NPM_SPT, and NPM_SPT is complete zero; The existing network network sends the system message of not carrying NPM_SPT;
802, portable terminal attempts obtaining the NPM_SPT in the system message, if do not obtain or get access to NPM_SPT for complete zero, thinks that then network do not support NPM TBF;
803, portable terminal sends the grouped channels resource request to network, requires to set up up TBF, carries wireless access capability (Radio Access Capability) cell in this message;
In this step, learnt network because of portable terminal and do not supported NPM TBF that so though portable terminal has carried the wireless access capability cell in request message, do not indicate whether to support NPMTBF in the cell, directly one or more TBF are set up in request;
804, after network receives the grouped channels resource request of up TBF,, be that portable terminal is assigned one or more up TBF by assignment messages according to self-ability;
805, after portable terminal is received this assignment messages, distinguish each TBF pattern according to " ARQ determination methods two ";
806, after portable terminal is judged the pattern of all TBF in the assignment messages,, begin on the grouped channels that up TBF distributes, to send uplink data block according to the scheduling of network according to the pattern of TBF separately.
Under this scene, system message is carried the function of NPM_SPT, also can be realized by the control signaling.
Because by said method, network is by informing message, setting up message and tell clearly that portable terminal is current and whether use non-persistent mode for its distribution T BF, the misunderstanding of having avoided network and portable terminal may occur the TBF pattern.Same, the different situations that the method also comprises appointment, switches and reshuffles also can be applicable to repeat no more under portable terminal and the various scenes of network to the different tenabilities of non-persistent mode herein.
The system that sets up to the Temporary Block Flow of the embodiment of the invention eight is described below, as shown in Figure 9:
This system comprises portable terminal and the base station that is connected with mobile terminal network.Wherein, portable terminal comprises message acquiring unit 901, judging unit 902 and is connected transmission unit 903.The base station comprises message sending unit 904 and linkage unit 905.
If portable terminal is supported NPM TBF:
In these cases, judging unit 902 sends to judged result and connects transmission unit 903, and the latter sets up TBF with the linkage unit 905 of network and is connected, and sends grouped data.
If portable terminal is not supported NPM TBF, receive the process of message and judge that the process that connects afterwards is the same, different is:
If described message is to set up message, judging unit 902 is made as judging: when RLC_MODE=0, be affirmation mode; When RLC_MODE=1, be Unacknowledged Mode.
If described message is to inform that message, judging unit 902 makes as judging: when RLC_MODE=0, be affirmation mode; When RLC_MODE=1, be Unacknowledged Mode.
This embodiment has carried the message of non-persistent mode sign to terminal by message sending unit 904 transmissions of network, terminal by obtain, deterministic process, allow portable terminal learn clearly and currently whether use non-persistent mode for its distribution T BF, the misunderstanding of having avoided network and portable terminal may occur the TBF pattern.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
