Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The schematic diagram of a kind of access process at random that triggers by false alarm information that Fig. 1 provides for embodiments of the invention, described method comprises:
S11: transfer of data is carried out in subscriber equipment and base station.
S12: subscriber equipment detects false alarm information, and resolves acquisition and insert relevant information at random.UE is in blind detection process, may detect that to obtain not be the PDCCH order that is issued by eNB, it is false-alarm PDCCH order, this order can be the 1A format physical downlink control channel commands, it is the PDCCH order of DCI1A, UE can obtain random access information by the indication of this false alarm information, the Preamble that random access information has indicated UE to be adopted when inserting at random, and described Preamble belongs to public Preamble sequence scope.
S13: subscriber equipment sends random access lead code according to the described indication that inserts relevant information at random to the base station.UE carries out non-competing solution according to the indication that inserts relevant information in the false alarm information at random and inserts at random, and promptly UE sends to eNB with the Preamble of false alarm information indication.
S14: the base station is the user equipment allocation temporary resource, and issues accidental access response message.After Preamble from UE was received in the base station, can take for was that new UE inserts, and eNB can be that this UE distributes relevant temporary resource, and issues RAR (Random Access Response, accidental access response) message, and begins to wait for the arrival of news 3.The described message 3 of present embodiment is to comprise C-RNTI (Cell Radio Network Temporary Identifier/Identity, Cell-RNTI) MAC CE (Control Element in up channel transmission, control unit) or CCCH (CommonControl Channel, Common Control Channel) SDU (Service Data Unit, Service Data Unit) message, this message solves to identify from high level and with the competition of UE and is associated, and is used for random access procedure.
S15: subscriber equipment resume data transmission.After UE receives RAR, think and insert successfully at random, and resume data transmission, message 3 no longer sent.
ENB can be in 3 the state of waiting for the arrival of news always after issuing RAR message, just the interim resource of distributing is discharged up to default timer expiry.Because the existence of false alarm information, transfer of data can be interrupted certain hour, and eNB to be UE distribute temporary resource and wait for the arrival of news and 3 also can cause the wasting of resources.
The schematic diagram of the access process at random that the another kind that Fig. 2 provides for embodiments of the invention is triggered by false alarm information, described method comprises:
S21: transfer of data is carried out in subscriber equipment and base station.
S22: subscriber equipment detects false alarm information, and resolves acquisition and insert relevant information at random.The UE blind Detecting obtains false-alarm PDCCH order, obtains random access information by the indication of this false alarm information, the Preamble that random access information has indicated UE to be adopted when inserting at random, and described Preamble belongs to non-public Preamble sequence scope.
S23: subscriber equipment sends random access lead code according to the described indication that inserts relevant information at random to the base station.
S24: it is not the dedicated preamble that this base station issues that the base station detects described random access lead code, does not carry out and inserts associative operation at random.For example, because the Preamble that receives is not that eNB oneself issues, this eNB can not continue to issue RAR message.
S25: subscriber equipment resends described random access lead code.UE waits for RAR message, if the RAR timer expiry then can resend and describedly insert the Preamble sequence at random, if still do not receive RAR message before the RAR timer expiry, UE can repeatedly send the described Preamble sequence that inserts at random, up to reaching maximum number of retransmissions.
S26: after subscriber equipment repeats to send described random access lead code and reaches maximum number of retransmissions, rebulid with the base station and to be connected.UE sends described special-purpose Preamble sequence and reaches can trigger after the default maximum times and rebuild flow process and eNB carries out link re-establishment, and is rebuilding successfully afterwards and eNB resume data transmission again.
Because UE sends the Preamble sequence many times in the present embodiment, transfer of data break period may be longer, caused that simultaneously unnecessary reconstruction founds flow process.
For reducing the access process at random that false alarm information triggers, need to determine that the PDCCH order that the UE blind Detecting obtains is order or the false-alarm order that eNB issues, the embodiment of the invention provides a kind of false alarm information detection method for this reason.The schematic diagram of a kind of false alarm information detection method that Fig. 3 provides for embodiments of the invention, described method comprises:
S31: obtain the 1A format physical downlink control channel commands.
S32: whether the setting of judging bit information in the described 1A format physical downlink control channel commands is satisfied pre-conditioned, if it is pre-conditioned that the setting of described bit information is not satisfied, determine that then described 1A format physical downlink control channel commands is a false alarm information, perhaps
Whether the preamble sequence of judging the indication of described 1A format physical downlink control channel commands number belongs to number set of default preamble sequence, if described preamble sequence number is not 0 and does not belong to number set of default preamble sequence, determines that then described 1A format physical downlink control channel commands is a false alarm information.
It is pre-conditioned to judge whether this PDCCH order is false alarm information whether present embodiment satisfies by the PDCCH order of judging DCI format 1A, if being provided with of the bit information of PDCCH order is unreasonable, perhaps the preamble sequence of PDCCH order indication number neither is 0 also not belong to the described preamble sequence number set of establishing, and then UE can confirm that described PDCCH order is false alarm information.The embodiment of the invention can prevent from the false alarm information misjudgement is the information that eNB issues, and can reduce the access process at random that false alarm information triggers, and improves data transmission stability.Further, UE can carry out above-mentioned 2 kinds of judgements simultaneously, to determine whether the PDCCH order is false alarm information, if any does not satisfy predetermined condition in described bit information and the described preamble sequence number, determine that then described PDCCH order is false alarm information, can increase the success rate that detects false alarm information like this, more help determining false-alarm PDCCH order, execution sequence for 2 kinds of judgment modes, present embodiment is not done qualification, and those skilled in the art can decide according to the actual requirements and at first carry out which kind of judgement.For example, if it is pre-conditioned that being provided with of described bit information satisfied, can't determine that the PDCCH order is the false-alarm order, whether the preamble sequence that then can continue to judge described 1A format physical downlink control channel commands indication number belongs to default preamble sequence number set, if described preamble sequence number is not 0 and does not belong to default preamble sequence number set, determines that then described 1A format physical downlink control channel commands is a false alarm information.If 2 times are judged the problem that all do not detect, then detected PDCCH order is not regarded as false alarm information.Similarly, UE can judge at first whether the preamble sequence of described 1A format physical downlink control channel commands indication number belongs to default preamble sequence number set, if this preamble sequence number belongs to default preamble sequence number set or is 0, all be normal, can not assert in view of the above that this PDCCH order is a false alarm information, then can continue to detect described bit information, determine according to bit information whether the PDCCH order is unusual, if it is unusual, can determine that this order is false alarm information, if judge for 2 times all to occur unusually, show that then this order is not the false-alarm order.Alternatively, UE is when detecting the PDCCH order for false alarm information, and discardable this PDCCH order makes UE can not continue to use this order.Number set of default preamble sequence in the present embodiment can comprise the whole special-purpose Preamble sequence number of the current eNB of UE, if the Preamble sequence number of indication is not the special-purpose Preamble of described eNB in the PDCCH that the UE blind Detecting the obtains order, can determine that then this PDCCH order is false alarm information.
Further, UE can judge in the described 1A format physical downlink control channel commands Resource Block be provided with the position whether be 1 and described 1A format physical downlink control channel commands in the reservation bit position whether be 0, if described Resource Block be provided with the position not all be 1 or described reservation bit position not all be 0, then the setting of described bit information is not satisfied pre-conditionedly, can determine that described 1A format physical downlink control channel commands is a false alarm information; If described Resource Block be provided with the position all be 1 and described reservation bit position all be 0, then being provided with of described bit information satisfied pre-conditionedly, the setting of bit information does not exist unusually in the then described PDCCH order, can not judge this order is false alarm information.Above-mentioned deterministic process is at existing LTE technology, because in the PDCCH of existing LTE technology order, all Resource Block is provided with position (Resource blockassignment bits) and is defined as 1, (Remaining bits) is defined as 0 in all reservation bit positions, if wherein regulation is not satisfied in the related bits position in the PDCCH order, then this PDCCH order is false alarm information.It will be understood by those skilled in the art that the regulation of existing protocol can change in follow-up technology evolution, for example all Resource Block is provided with the position and also can be defined as 0; Perhaps all Resource Block are provided with in the position partial bit position and can be defined as 0 and another part bit can be defined as 1, this moment, respective change can take place in the Rule of judgment to bit information in the PDCCH order, as long as it is pre-conditioned that the setting of described bit information is not satisfied, can think that all this PDCCH order is the unreasonable message of false-alarm.ENB available resources piece is provided with the position to the available Resource Block of UE indication in the present embodiment, is a kind of available resource block indication information; The reservation bit position then is a still untapped bit in the present agreement.Be appreciated that, evolution along with the LTE technology, new PDCCH order may appear for follow-up, the bit information of described new appearance order also may change, the bit of other various realization deixises for example may appear being used to realize, being provided with of these bits can have special regulation, and whether the setting that still can judge described bit this moment is satisfied default regulation and determined whether PDCCH orders is false alarm information, and present embodiment does not limit this.
