Description
Technical field
The present invention relates to the radio communication channel control technology, particularly a kind of indicating means of ascending control channel and device.
Background technology
At GPRS (GPRS, General Packet Radio Service) and the GPRS (EGPRS that strengthens, Enhanced GPRS) in the technology, distribute to the time slot (TS of GPRS/EGPRS, Timeslot) be called Packet Data Channel (PDCH, Packet Data Channel), grouped data is in repeating process, travelling carriage (MS, Mobile Station) and need between the network to set up interim the connection by air interface, promptly set up Temporary Block Flow (TBF, Temporary Block Flow) connection, network distributes Temporary Block Flow indication (TFI, Temporary Flow Identity) for each TBF, and GPRS/EGPRS supports a MS to have a plurality of TBF to connect in one direction, a TBF can use Radio Resource on one or more PDCH, also can be a plurality of TBF simultaneously multiplexing on same PDCH, among multiplexing a plurality of TBF on same PDCH, use different TFI to distinguish each TBF simultaneously.
In the GPRS/EGPRS network, each TBF has the grouping assist control channel (PACCH of a correspondence, Packet Associated Control Channel), comprise downlink grouped assist control channel (PACCH/D, PACCH/Downlink) and upstream packet assist control channel (PACCH/U, PACCH/Uplink), this PACCH is mapped on the PDCH at its corresponding TBF place.For example, network is a certain MS allocation of downlink TBF1 on descending PDCH1, PDCH2, PDCH3, and when network carried out poll (poll) to TBF1 on which descending PDCH, MS just transmitted control message on the up PDCH of this TBF1 correspondence.
Fig. 1 is that the up PACCH of the descending TBF correspondence of prior art is mapped in the schematic diagram on the identical up PDCH, referring to Fig. 1, TBF uses Radio Resource on PDCH1, PDCH2 and PDCH3, when network on descending PDCH2 during to the TBF1 poll, MS just transmits control message on the up PDCH2 of correspondence.
If being a certain MS, network distributed a plurality of TBF or TBF to use a plurality of Radio Resources, because the multislot capability of MS is the MS timeslot number that can receive, the timeslot number that can send and from the restriction of time slot change-over time of receiving that transmission needs for example, if still on the up PDCH of correspondence, transmit control message, MS will occur and occur in the situation that same time slot receives descending TBF and FEEDBACK CONTROL message simultaneously, this is unallowed for MS.The method that solves is that a plurality of TBF or the TBF with this MS uses the PACCH of a plurality of Radio Resource correspondences to be mapped on the identical PDCH, network passes through when descending TBF configuration and resource reconfiguration, upload control time slot (Uplink controltimeslot) is set, promptly set up or the assignment messages of reprovision at indicating downlink TBF, as the grouping downlink assignment messages, many TBF downstream assigned, the grouping time slot is reshuffled, many TBF time slot is reshuffled, the grouping switching command, the field of indication Uplink control timeslot is set in the message related news such as grouping CS release indication, come instruct MS to go up the control messages that sends specific T BF at which ascending time slot number (TN, Timeslot Number); And, when network is provided with correlation reserved block period (RRBP in a certain descending radio block, Relative Reserved Block Period) when carrying out poll, MS up-link wireless piece according to the RRBP indication on the time slot of Uplink control timeslot indication sends grouping control acknowledge message (PACKET CONTROL ACKNOWLEDGEMENT MESSAGE) or other control messages.
When Fig. 2 disposes a plurality of TBF for prior art MS and is subjected to the multislot capability restriction, the up PACCH of a plurality of TBF correspondences is mapped in the schematic diagram of identical PDCH, referring to Fig. 2, network is that MS has distributed 3 TBF, respectively at PDCH1,2, on 3, owing to limited by multislot capability, the up PACCH of a plurality of TBF correspondences is mapped on the identical PDCH, promptly in assignment messages, carry out the configuration of Uplink control timeslot=TN2, therefore, no matter network carries out poll (promptly asking at descending PDCH1 or 2 or 3 enterprising road wheels) to TBF1 or 2 or 3, MS transmits control message on PDCH2, the situation that can't receive descending TBF that causes in the time of can avoiding MS to transmit control message.
Fig. 3 is limited by multislot capability when disposing many TBF for prior art MS, ascending control channel configuration flow schematic diagram, and referring to Fig. 3, being configured in descending TBF configuration and the resource reconfiguration flow process of ascending control channel carried out, and idiographic flow comprises:
In step 301, (NW Network) sends grouping downlink to MS and assigns many TBF of Packet Downlink Assignment/ downstream assigned Multiple TBF Downlink Assignment message network;
In this step, the MS multislot capability of network based service request and storage sends grouping downlink appointment/many TBF downstream assigned message to MS, and disposes Uplink control timeslot=TN2 in message.
In step 302, NW sends to MS and carries the descending TBF1 data block Downlink TBF1 data block with valid RRBP of effective correlation reserved block period information;
In step 303, MS sends PACCH/U TBF1 control messages PACCH/U for TBF1 on Uplink TN2 at up TN2 time slot;
In step 304, NW sends to MS and carries the descending TBF2 data block Downlink TBF2 data block with valid RRBP of effective correlation reserved block period information;
In step 305, MS sends PACCH/U TBF2 control messages PACCH/U for TBF2 on Uplink TN2 at up TN2 time slot;
In step 306, (NW Network) reshuffles many TBF of Packet Timeslot Reconfigure/ time slot to MS transmission grouping time slot and reshuffles Multiple TBF Timeslot Reconfigure message network;
In this step, configuration Uplink control timeslot=TNx in grouping time slot reconfiguration message.
In step 307, NW sends to MS and carries the descending TBF1 data block Downlink TBF 1data block with valid RRBP of effective correlation reserved block period information;
In step 308, MS sends PACCH/U TBF1 control messages PACCH/Ufor TBF1 on Uplink TN2 at up TNx time slot;
In step 309, NW sends to MS and carries the descending TBF2 data block Downlink TBF2 data block with valid RRBP of effective correlation reserved block period information;
In step 310, MS sends PACCH/U TBF2 control messages PACCH/Ufor TBF2 on Uplink TN2 at up TNx time slot;
In existing GPRS/EGPRS network, a time division multiple access (TDMA, Time Division Multiple Access) frame is made up of 8 time slots, and transfer of data is radio block (Block) at the minimum scheduling unit of physical layer, each Block is made up of 4 time slots, lay respectively at 4 continuous tdma frames, so Transmission Time Interval (TTI of each Block, Transmission Timing Interval) be 20ms, be referred to as basic Transmission Time Interval (BTTI, Basic TTI), such Block is referred to as BTTIBlock.
