202: according to said RNTI resource, with the user equipment (UE) access network.
In order more clearly to set forth the present invention, below the cut-in method of the network that provides of the present invention is carried out detailed introduction through concrete access process:
As shown in Figure 3, the cut-in method of a kind of network that the embodiment of the invention provides below is that example describes with UE through the flow process of a via node access network.
LTE system uplink coverage is by the decision of control signaling coverage, when RN is deployed in its eNB coverage edge or beyond the eNB coverage time, the UE in the RN coverage need be through via node RN from the correct reception control signaling of eNB.The concrete realization flow of the access network at random of UE is following in the RN coverage:
301:eNB distributes the RNTI resource for via node RN; Described eNB be via node distribute the RNTI resource mode can for: the static allocation mode or the semi-static method of salary distribution, promptly said eNB allocates its part RNTI resource to RN in advance with the static allocation mode or the semi-static distribution method of salary distribution.
302: when UE needed access network, UE mated the RN system broadcast information that receives and himself sequence; If mate successfully, then accomplish the down-going synchronous of UE and RN.
303:UE sends and inserts request message at random to RN; Wherein, the described access in the request at random carries random access leader sequence (Preamble).UE sends to insert at random and asks to give the concrete implementation procedure of RN following:
At first, UE selectes Preamble, if UE has been assigned with Preamble, then uses this Preamble, otherwise UE selects a group among two groups of Preamble of sub-district internal fixation; Then; UE is according to Physical Random Access Channel (the Physical Random Access Channel that reads from the RN system broadcasts; Abbreviation PRACH) position; Selected Preamble is sent to RN on the PRACH channel, the power of transmission can be controlled the initial power that (Radio Resource Control is called for short RRC) layer configures for Radio Resource.
304: after RN received the request message of access at random from UE, RN sent repeated link ascending resource request (Uplink Source Require is called for short UL SR) message to eNB, and this UL SR message is used for the RRC Signalling exchange.
305: after RN received the request message of access at random from UE, RN replied an accidental access response message to UE; Described accidental access response message comprises: ascending resource distributes permission (UL grant) transmission RRC connection to set up the indication of request message, up time synchronized adjustment (Timing Advance; Be called for short TA) with the interim sub-district of distributing to the user ID (Temporary Cell-Radio NetworkTemporary Identifier, abbreviation TC-RNTI) of eating dishes without rice or wine.
Wherein, UE is following in the process of receiving random access response message:
UE monitors the PDCCH channel at one or several Transmission Time Interval (Transmission Timing Interval is called for short TTI) in the window time, be used for obtaining downlink resource and distribute (Downlink assignment is called for short DL assigment) indication.UE distributes indication to go up receiving random access response message at Physical Downlink Shared Channel (Physical downlink share channel is called for short PDSCH) according to said downlink resource, after UE receives accidental access response message, and UE and RN uplink synchronous.
After 306:eNB receives the UL SR message from RN, feed back a repeated link uplink resource allocation permission (UL grant) that is used to transmit next RRC signaling to RN.
307:UE sends RRC according to the UL grant that carries in the accidental access response message that receives in the step 305 and connects the indication of setting up request message, sends the RRC connection request of setting up and gives RN, and RN can set up route table items for this UE.Wherein, having carried RN in the described RRC connection foundation request is the TC-RNTI of UE distribution and the ID of non-access sublayer (Non-access stratum is called for short NAS).
308: after RN received the RRC connection foundation request from UE, RN sent repeated link RRC connection to this UE to eNB according to the UL grant that receives in the step 306 and sets up request message; Described repeated link RRC connects that to set up request message except carrying RN be the TC-RNTI that distributes of UE and the ID of NAS layer; Also carry RRC and set up reason item (RRC establishment cause) and RN self information; Like the RNTI of this RN, this RRC sets up reason item and RN self information, and to be used to indicate this RRC to connect the request of foundation be to come from the connection of the UE this RN under to set up and ask.
309:RN receive from the RRC of UE connect set up request message after, reply access link RRC to UE and connect and set up message.
310:eNB receive from the repeated link RRC of RN connect set up request message after, utilize the TC-RNTI of the UE that carries in this message, can set up route table items for this UE, and reply repeated link RRC to RN and connect and set up message.
What be worth explanation is, RN described in the step 309 replys access link RRC to UE and connects and set up in message and the step 310 eNB and be connected the sending order of setting up message to RN answer repeated link RRC and do not do qualification.
After 311:UE correctly receives RRC connection foundation; TC-RNTI is upgraded to the ID of eating dishes without rice or wine in the sub-district (Cell Radio Network Temporary Identifier; Be called for short C-RNTI); Be that UE confirms as C-RNTI with described TC-RNTI, RN can not give described TC-RNTI other UE again.At this moment, UE replys the RRC connection setup complete message to RN.Carried in the described RRC connection setup complete message and given the Mobility Management Entity Non-Access Stratum of (Mobile management entity is called for short MME) (Non-access stratum is called for short NAS) message, i.e. services request (Service Request) message.
After 312:RN receives the RRC connection setup complete message from UE, can upgrade the route table items of this UE, send repeated link RRC connection setup complete message to eNB then, and be carried in this repeated link message for the NAS message of MME UE.
What be worth explanation is that RN also can be at UE before RN sends access link RRC connection setup complete message to the repeated link RRC connection setup complete message that eNB sends.In this case, RN is behind the access link RRC connection setup complete message that receives the UE transmission, and RN need trigger a repeated link message again, and this repeated link message is used for giving eNB for the NAS forwards of MME UE, is transmitted to MME by eNB again.
After 313:eNB receives the RRC connection setup complete message that comprises UE NAS message, can the corresponding route table items that upgrades this UE, and this NAS message is encapsulated in the S1-AP message is transmitted to MME; What be worth explanation is to have comprised the operation of routing update here, so need in initial the access, not start a routing update flow process specially.
315:MME sends S1-AP (the S1-AP Initial ContextSetup Request) message of UE initial context foundation request and gives eNB, and the radio bearer and the S1 that activate the packet switching system (Active EPSEvolved Packet System) that is used for all evolution carry.ENB is with safe context; MME signaling connection identifier (Identifier; Be called for short ID), bearer quality of service context (Quality of Service profile is called for short QoS profile) and S1 Tunnel Identifier (S1-Tunnel End Point Identifier; Be called for short S1-TEID) be stored in wireless access network (Radio Access Network the is called for short RAN) context.
Before MME carries out initial UE context setup flow process, in the present embodiment, can further comprise alternatively and carry out reliability certification between step 314:UE and the MME.
316: after receiving the UE initial context, eNB starts the security configuration flow process and RRC reshuffles flow process.
After 317:eNB receives that safe mode is accomplished affirmation, send the S1-AP message (S1-AP Initial Context Setup Complete) of an initial context foundation completion and give MME, the UE networking flow process under the whole RN is accomplished.
The cut-in method of a kind of network that present embodiment provides is that via node distributes the RNTI resource through eNB, thereby makes that UE is the RNTI access network that said via node distributes through eNB.So just make via node carry out information interaction, thereby realize that the user is through the via node access network through information and network side base station that its user side that receives sends.
As shown in Figure 4, the cut-in method of a kind of network that the embodiment of the invention provides below is that example describe through at least two via nodes with the flow process of distributed access way access network with UE.Its concrete realization flow is following:
Step 401 to step 402 repeats no more with reference to step 301 to the step 302 in embodiment illustrated in fig. 3 here.
403:UE sends and inserts request message at random to RN; Wherein, the described access in the request at random carried Preamble.UE sends to insert at random and asks to give the concrete implementation procedure of RN following:
At first, UE selectes Preamble, if UE has been assigned with Preamble, then uses this Preamble, otherwise UE selects a group among two groups of Preamble of sub-district internal fixation; Then, UE sends to RN with selected Preamble according to the position of the PRACH that reads from the RN system broadcasts on the PRACH channel, the initial power that the power of transmission can configure for rrc layer.
404: after RN received the request message of access at random from UE, RN sent repeated link UL SR message to next RN successively, described repeated link UL SR message is sent to eNB always, and UL SR message is used for the RRC Signalling exchange.
405: after RN received the request message of access at random from UE, RN replied an accidental access response message to UE; Described accidental access response message comprises: ascending resource distributes permission to send RRC and connects indication, TA and the TC-RNTI that sets up request message.
Wherein, UE is following in the process of receiving random access response message:
UE monitors the PDCCH channel in one or several TTI window time, be used for obtaining DL assigment indication.UE indicates receiving random access response message on PDSCH according to said DL assigment, after UE receives accidental access response message, and UE and RN uplink synchronous.
After 406:eNB received the UL SR message from RN, at first the feedback UL grant that is used to transmit next RRC signaling gave a RN nearest with it, then, successively said UL grant is sent to a RN nearest with UE.
407:UE sends RRC according to the UL grant that carries in the accidental access response message that receives in the step 405 and connects the indication of setting up request message, sends the RRC connection request of setting up and gives a nearest RN of this UE, and RN can set up route table items for this UE.Wherein, having carried RN in the described RRC connection foundation request is the ID of the TC-RNTI of UE distribution with NAS.
408: when with after the nearest RN of UE receives that RRC from UE is connected the request of foundation; RN sends repeated link RRC connection to this UE and sets up request message to next RN; Every through a RN; RN will send to eNB up to request message is set up in said repeated link RRC connection for this UE sets up route table items; Described repeated link RRC connects and sets up request message to connect the RN that sets up in the request message be the TC-RNTI that distributes of UE and the ID of NAS layer except carrying RRC that UE sends, also carry RRC set up the reason item with and the relevant information of the RN that passed through.
409:RN receive from the RRC of UE connect set up request message after, reply access link RRC to UE and connect and set up message.
410:eNB receive from the repeated link RRC of RN connect set up request message after; The TC-RNTI that utilizes the UE that carries in this message with and the relevant information of the RN that passed through; Can be for this UE set up route table items, and reply repeated link RRC to RN and connect and set up message.
What be worth explanation is, RN described in the step 409 replys access link RRC to UE and connects and set up in message and the step 410 eNB and be connected the sending order of setting up message to RN answer repeated link RRC and do not do qualification.
411:UE upgrades to C-RNTI with TC-RNTI after correctly receiving RRC connection foundation, and promptly UE confirms as C-RNTI with described TC-RNTI, and RN can not give described TC-RNTI other UE again.At this moment, UE replys the RRC connection setup complete message to RN.Carried a NAS message of giving MME in the described RRC connection setup complete message.
After 412:RN receives the RRC connection setup complete message from UE; Can upgrade the route table items of this UE; Successively repeated link RRC connection setup complete message is transmitted to eNB through a plurality of RN then, and is carried in this repeated link message for the NAS message of MME UE.Wherein, described repeated link RRC connection setup complete message whenever all can carry its routing iinformation through a RN when transmitting through a plurality of RN successively.
What be worth explanation is that RN also can be at UE before RN sends access link RRC connection setup complete message to the repeated link RRC connection setup complete message that eNB sends.In this case, RN is behind the access link RRC connection setup complete message that receives the UE transmission, and RN need trigger a repeated link message again.Described repeated link message is used for giving eNB for the NAS forwards of MME UE, is transmitted to MME by eNB again.
In sum, step 403 to step 412 is that with the different of the above-mentioned step of mentioning 303 to step 312 described UE is through at least two via node access networks.Through in the process of a via node access network, UE need send repeated link message and eNB carries out information interaction through via node at the UE shown in Fig. 3; And access procedure shown in Figure 4, UE then need transmit said repeated link message through a plurality of via nodes could carry out information interaction with eNB; Being that described repeated link message is every all adds the relevant information of process via node in the repeated link message to through a via node; And then give next via node with the repeated link forwards of the relevant information of having added via node; Up to sending to eNB; Thereby make to be in beyond the eNB coverage and also can carry out information interaction, access network with eNB through a plurality of RN transfers than UE at a distance.
