Whether, in the present embodiment, the UE being configured with EAB once receives the DCI1X of existing RNTI scrambling, the most currently have access request to need to initiate, and EAB information comes into force at once, and timer starts timing, and such network side, as eNB is controlled for the time of its effect of EAB.The up-to-date EAB information received as UE can cover before information, and timer restarts.After not receiving new EAB information and timer expired, it is believed that the most several times there is no EAB, access request can be initiated to network side.
In the present embodiment, PDCCH includes DCI1A, and alternatively, Access Control information is carried on DCI1A by network equipment, uses P-RNTI to scramble DCI1A, and described Access Control information is carried on the reserved bit position in the DCI1A after described scrambling.In the present embodiment, use P-RNTI that CRC is scrambled in DCI1A, HARQ (HybridAutomaticRepeatRequest therein, hybrid automatic repeat-request) process number (3bits) is reserved, so i.e. can carry EAB information on reserved bit with the spare bits of this 3bit of multiplexing for the UE being configured with EAB.Such as can index with wherein 2 bit, the UE that representative is not prohibited by UE access, generation random number is less than 0.3 forbids that the UE that access, generation random number are less than 0.5 forbids that the UE that access, generation random number are less than 0.8 forbids access etc.；1 bit can also be separated and do the index of EAB time.If 3bit all makees probability factor index, then need one the EAB time of over-specification.
Except HARQ process, also has PUCCH (PhysicalUplinkControlCHannel, physical uplink control channel) bit in power control territory can use, for TDD system, it is also possible to the DownlinkAssignmentIndex (downlink indicator of distribution) of 2bit can use.
When network side determines to start EAB when, the reserved bit position of DCI1A carries EAB information, by PDCCH corresponding for DCI1A, EAB information is handed down to be configured with the UE of EAB, described PDCCH is resolved by the UE being correspondingly configured with EAB, obtain the described Access Control information after descrambling, including: judge whether described DCI1A scrambles with P-RNTI, if it is read the reserved bit position in described DCI1A, obtain Access Control information.In the present embodiment, it is configured with the UE of EAB, at any time receives the DCI1A of P-RNTI scrambling, all detect the 3bit in HARQ process number territory, and be considered as up-to-date EAB information.The up-to-date EAB information that UE receives can cover before information, and timer restarts.After not receiving new EAB information and timer expired, it is believed that there is no EAB, access request information can be initiated to network side.
In the present embodiment, require that eNB can not arbitrarily arrange the reserved bit position of DCI1A, need to be considered as EAB information and arrange, i.e. without EAB demand, again common UE is sent the DCI1A of P-RNTI scrambling, HARQ process number territory is set to the index being not prohibited by accessing.Wherein, common UE refers to not configure the UE of EAB.
The method of the Access Control that the embodiment of the present invention provides can coordinate with traditional EAB scheme based on SIB, it is also possible to individually becomes EAB scheme, as described below:
(1) when the present embodiment provides the method for Access Control and EAB scheme based on SIB coordinate:
In the present embodiment, when network side determines to start EAB when, send the quick EAB information of PDCCH so that the UE being configured with EAB stops accessing.Meanwhile, at next system broadcasts change cycle change SIB.EAB information in the PDCCH that UE receives is the most expired, when having read again EAB information based on SIB, is as the criterion with the EAB information of SIB, performs Access Control.EAB parameter/the intervalometer relevant to PDCCH all discharges.
In the present embodiment, connection for Quick stop UE, send PDCCH to UE, first terminate the access of UE, meanwhile, the broadcast of change system, in broadcast, add the strategy that network side is new, be broadcast to UE the most again, after UE receives broadcast, it is as the criterion with the information in broadcast, performs Access Control.The UE of configuration EAB is after receiving PDCCH and performing EAB, some variable and timer are assigned, such as access probability factor, also it is prohibited timer of time etc., so after hearing the EAB information of broadcast, will be all rinsing out according to the relevant assignment of the quick EAB of PDCCH reception before, assignment again.
(2) when the method controlling to access that the present embodiment provides is used alone:
In the present embodiment, PDCCH can be individually used to issue Access Control information, the PDCCH that UE only issues in this case based on network side.
But, after network side have sent the EAB that PDCCH carries, have UE access network that is that newly wake up up or that move to this community.These UE do not know before the EAB information that sends of PDCCH, it is believed that do not have EAB to control information, it is possible to normal access network.In this case, in community, real EAB access probability factor slowly can increase owing to community increases EABUE newly, the EAB probability factor carried in deviation PDCCH.After network side detects the change of access probability factor, can be according to self control algolithm, the in good time EAB parameter of transmission again, to solve the deviation of EAB probability factor.
The embodiment of the method that the present invention provides provides the benefit that: Access Control information is carried on PDCCH be handed down to be configured with the UE of Access Control by network equipment, UE is enable to timely receive Access Control information and no longer to ask the connection with network side according to control information in time, so make the UE being configured with Access Control will not take the resource of H2H user network congestion when, thus solve the UE being configured with Access Control in traditional approach and be also connected with network side in request within the change cycle of broadcast, seize H2H user resources, cause H2H conversation loss, thus the problem affecting H2H user's communication quality.Meanwhile, Access Control information can be handed down to UE by different DCI format, it is achieved convenient, easily operates.
