Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 2, the system of embodiment of the invention message transmission comprises: network equipment 10 and user terminal 20.
Wherein, initial NAS message comprises but not to be limited to a kind of in the following message:
NAS Service Request (NAS service request), NAS Attach (NAS adheres to) and NASTracking Area Update (renewal of the NAS band of position) etc.
Wherein, user terminal 20 sends the Preamble sign indicating number to network equipment 10, and network equipment 10 is determined first sub-frame of uplink and second sub-frame of uplink after receiving the Preamble sign indicating number.
Concrete, user terminal 20 is that inserting at random of purpose initiated under the idle state with initial access.
The MAC of user terminal 20 (Media Access Control, the medium access control) layer is initiated random access procedure, according to Msg (message) 3 sizes, Group A, Group B and path loss information etc. are selected suitable Preamble group, picked at random Preamble in selected group goes up transmission Preamble at suitable Prach (Physical Random Access Channel).
Especially, if user terminal 20 is R10UE, can utilize methods such as special P reamble or Prach resource to inform that network equipment 10 self is R10UE.
Wherein, it is multiple that first sub-frame of uplink that network equipment 10 bases are determined and second sub-frame of uplink determine that the mode of resource indication information has, and enumerates several below:
Mode one, be applicable to that the resource of distributing to user terminal 20 in the resource of distributing to user terminal 20 in first sub-frame of uplink and second sub-frame of uplink is identical.
In specific implementation process, distribute to the resource of user terminal 20 in network equipment 10 is distributed to user terminal 20 in first sub-frame of uplink resource and second sub-frame of uplink when identical, with UL grant (ascending resource distribution) information of identical resource correspondence as resource indication information.
Accordingly, the resource of user terminal 20 by first sub-frame of uplink of UL grant information indication sends RRC and connects and set up request message, and the resource of second sub-frame of uplink by the indication of UL grant information sends initial NAS message.
Because it is identical to distribute to the resource of user terminal 20 in the resource of distributing to user terminal 20 in first sub-frame of uplink and second sub-frame of uplink, so only need a UL grant information to get final product.
In specific implementation process, network equipment 10 can send accidental access response message to user terminal 20 in the Msg2 window, wherein comprise UL grant information; After the MAC layer of user terminal 20 receives accidental access response message, on corresponding resource, sending Msg3 (promptly comprise RRC and connect the message of setting up request message) and initial NAS message according to the indication of UL grant information.
Concrete, user terminal 20 with first sub-frame of uplink after the Msg26ms that receives as the transmission upstream data moment (i.e. first sub-frame of uplink) that is UL grant appointment.
For mode one, can adopt the position of implicit expression notice or explicit notification mode informing user terminal 20 second sub-frame of uplink.
The implicit expression advice method can be stipulated in agreement in advance, as long as then user terminal 20 is received accidental access response message, and after having determined first sub-frame of uplink according to accidental access response message, with an immediate sub-frame of uplink after first sub-frame of uplink as second sub-frame of uplink.Continuous two sub-frame of uplink that promptly use the Msg3 subframe to begin send RRC message and initial NAS message respectively.
The explicit notification mode can be by the position of network equipment 10 informing user terminals 20 second sub-frame of uplink.Concrete, network equipment 10 as resource indication information, is used for the subframe indication information indicating user terminal 20 and determines second sub-frame of uplink according to the subframe indication information; Accordingly, user terminal 20 just can be determined second sub-frame of uplink according to the subframe indication information.
The subframe indication information can be to be used for distinguishing a frame or two frames, can only represent with 0 or 1; Such as 0 expression conventional allocation mode (being only to distribute a sub-frame of uplink resource in the accidental access response in order to transmission Msg3), continuous two sub-frame of uplink that 1 expression uses the Msg3 subframe to begin send RRC message and initial NAS message respectively; Then user terminal 20 is after receiving 1, with an immediate sub-frame of uplink after first sub-frame of uplink as second sub-frame of uplink.
The subframe indication information can also be represented the position of second sub-frame of uplink, such as 3, represents that then the 3rd sub-frame of uplink is second sub-frame of uplink after first sub-frame of uplink.
The subframe indication information can adopt the 1bit R in MAC RAR (MAC accidental access response) form to indicate, and also can indicate with other modes.
Mode two, be applicable to that the resource of distributing to user terminal 20 in the resource of distributing to user terminal 20 in first sub-frame of uplink and second sub-frame of uplink is different.
In specific implementation process, network equipment 10 in first sub-frame of uplink, distribute to distribute to user terminal 20 in the resource of user terminal 20 and second sub-frame of uplink resource not simultaneously, UL grant information with the resource correspondence of first sub-frame of uplink, and the 2nd ULgrant information of the resource correspondence of second sub-frame of uplink sends to user terminal as resource indication information.
Accordingly, the resource of user terminal 20 by first sub-frame of uplink of UL grant information indication sends RRC and connects and set up request message, and the resource of second sub-frame of uplink by the indication of the 2nd UL grant information sends initial NAS message.
Because it is different to distribute to the resource of user terminal 20 in the resource of distributing to user terminal 20 in first sub-frame of uplink and second sub-frame of uplink, so two UL grant information all need be sent to user terminal 20.
In specific implementation process, can expand the resource of corresponding first sub-frame of uplink in first UL grant territory, the resource of second corresponding second sub-frame of uplink in UL grant territory to UL grant territory.
For mode two, can adopt the position of implicit expression notice or explicit notification mode informing user terminal 20 second sub-frame of uplink.
In the mode two in implicit expression notice and explicit notification side and the mode one implicit expression notify identically with the explicit notification mode, do not repeat them here.
Mode three, employing PDCCH (physical downlink control channel, Physical Downlink Control Channel) schedule information mode.
Accordingly, the resource of user terminal 20 by first sub-frame of uplink of UL grant information indication sends RRC and connects and set up request message, and the resource of second sub-frame of uplink by the indication of PDCCH schedule information sends initial NAS message.
Concrete, the moment that network equipment 10 sends PDCCH need guarantee that second sub-frame of uplink is positioned at after first sub-frame of uplink, and is positioned at before the RRC connection foundation request, the resource of PDCCH indication can be distributed by existing dispatching algorithm;
Accordingly, user terminal 20 is received PDCCH, and first sub-frame of uplink after 4ms (i.e. second sub-frame of uplink) sends data according to the resource of PDCCH indication.
In specific implementation process, network equipment 10 can send accidental access response message to user terminal 20 in the Msg2 window, wherein comprise UL grant information, supposes that the moment of transmission accidental access response message is t;
After the MAC layer of user terminal 20 received accidental access response message, the indication according to ULgrant information after 6ms sent Msg3 on corresponding resource, i.e. delivery time=t+6;
Wherein, user terminal 20 can place initial NAS message among the SRB (Signal Radio Bear, Signaling Radio Bearer) 0, sends by CCCH (Common Control Channel, Common Control Channel) channel.
Accordingly, in the message of CCCH carrying, need to increase initial NAS message, specifically referring to table 1:
Table 1
Initial NAS message definition is as follows:
Signalling radio bearer (Signaling Radio Bearer): SRB0
RLC-SAP (RLC transmission mode): TM
Logical channel (logic channel): CCCH
Direction (direction): UE to E-UTRAN
Table 2UL Information Transfer CCCH message (at the NAS of CCCH channel message format).
If request message is set up in the RRC connection and initial these two signalings of NAS message all send by CCCH, because RLC (Radio Link Control, Radio Link control) transmission mode is TM (TransparentMode, transparent mode), TM does not have the function that reorders, if these two message occur out of order and lose and can take following method to solve:
At the MAC layer these two message are reordered.
The MAC layer of network equipment 10 is known two signalings running time-frequency resource and progress information separately, can introduce particular processing to the reception of these two message, guarantees to submit according to the order of sequence.For example, when request message is set up in the RRC connection also less than correct the reception, if initial NAS message is correctly received, then carry out buffer memory at the MAC layer, connect until RRC and to set up request message and receive again two message are forwarded to high level according to the order of sequence, the perhaps RRC transmission of messages failure NAS message of then deleting buffer memory is thought procedure failure.
Concrete, network equipment 10 was received initial NAS message, the initial NAS message that buffer memory is received before receiving that request message is set up in the RRC connection;
After receiving that request message is set up in the RRC connection, connect initial NAS message and the user terminal 20 of setting up request message and buffer memory according to RRC and connect; Or do not receive that in setting-up time RRC connects when setting up request message, the initial NAS message of deletion buffer memory.
At rrc layer these two message are handled.
If the rrc layer of network equipment 10 has been received initial NAS message earlier, then set up MME and be connected (promptly send to MME, make MME initiate to set up process) with user terminal 20, treat that RRC connects to set up request message and receive, begin to set up RRC again and connect.Set up the request message failure if follow-up RRC connects, then delete MME and connect.
Concrete, network equipment 10 was received initial NAS message before receiving that request message is set up in the RRC connection, set up MME according to initial NAS message with user terminal 20 and be connected;
Receive RRC connect set up request message after, connect according to RRC and to set up request message and set up RRC with user terminal 20 and be connected; Or not receiving that in setting-up time RRC connects when setting up request message, the MME that deletion is set up connects.
If initial NAS message sends failure, the embodiment of the invention also provides a kind of re-transmission scheme:
If user terminal 20 determines that initial NAS message sends failure, initial NAS message can be placed the RRC connection setup complete message, send to network equipment 10.
After determining that according to the ACK/NACK feedback initial NAS message sends failure such as the MAC layer of user terminal 20, can report to the rrc layer of user terminal 20, the rrc layer of user terminal 20 places the RRC connection setup complete message with initial NAS message, sends to network equipment 10.
Wherein, the network equipment of the embodiment of the invention can be the base station, also can be other equipment of network side, can also be the new equipment of network side.
As shown in Figure 3A, first kind of network equipment of the embodiment of the invention comprises: subframe determination module 100 and information sending module 110.
In specific implementation process, subframe determination module 100 can be determined first sub-frame of uplink and second sub-frame of uplink after receiving from the Preamble sign indicating number of user terminal.
Wherein, it is multiple that first sub-frame of uplink that information sending module 110 bases are determined and second sub-frame of uplink determine that the mode of resource indication information has, and enumerates several below:
Mode one, be applicable to that the resource of distributing to user terminal in the resource of distributing to user terminal in first sub-frame of uplink and second sub-frame of uplink is identical.
For mode one, can adopt the position of implicit expression notice or explicit notification mode informing user terminal 20 second sub-frame of uplink.
The implicit expression advice method can be stipulated in agreement in advance, as long as then user terminal is received accidental access response message, and after having determined first sub-frame of uplink according to accidental access response message, with an immediate sub-frame of uplink after first sub-frame of uplink as second sub-frame of uplink.
The explicit notification mode can be by information sending module 110 with the subframe indication information as resource indication information, be used for indicating user terminal and determine second sub-frame of uplink according to the subframe indication information.
Mode two, be applicable to that the resource of distributing to user terminal in the resource of distributing to user terminal in first sub-frame of uplink and second sub-frame of uplink is different.
In specific implementation process, information sending module 110 is with a UL grant information of the resource correspondence of first sub-frame of uplink, and the 2nd UL grant information of the resource correspondence of second sub-frame of uplink is as resource indication information, send to user terminal, wherein a UL grant information is used to indicate the resource of first sub-frame of uplink of distributing to user terminal, and the 2nd UL grant information is used to indicate the resource of second sub-frame of uplink of distributing to user terminal.
For mode two, can adopt the position of implicit expression notice or explicit notification mode informing user terminal 20 second sub-frame of uplink.
In the mode two in implicit expression notice and explicit notification side and the mode one implicit expression notify identically with the explicit notification mode, do not repeat them here.
Mode three, employing PDCCH schedule information mode.
If request message is set up in the RRC connection and initial these two signalings of NAS message all send by CCCH, because the transmission mode of RLC is TM, TM does not have the function that reorders, if these two message occur out of order and lose also needing to carry out respective handling, two kinds of schemes is arranged specifically:
The network equipment of scheme one, the embodiment of the invention can further include: first processing module 120, and referring to Fig. 3 B.
After receiving that request message is set up in the RRC connection, connect initial NAS message and the user terminal of setting up request message and buffer memory according to RRC and connect; Or do not receive that in setting-up time RRC connects when setting up request message, the initial NAS message of deletion buffer memory.
The network equipment of scheme two, the embodiment of the invention can further include: second processing module, 1 equipment 130, and referring to Fig. 3 C.
Receive RRC connect set up request message after, connect according to RRC and to set up request message and set up RRC with user terminal and be connected; Or not receiving that in setting-up time RRC connects when setting up request message, the MME that deletion is set up connects.
As shown in Figure 4, embodiment of the invention user terminal comprises: receiver module 200 and message transmission module 210.
Wherein, if resource indication information comprises a UL grant information, resource and the resource of second sub-frame of uplink of message transmission module 210 by first sub-frame of uplink of the UL grant information in resource indication information indication sends RRC respectively and is connected the resource of setting up the request message and second sub-frame of uplink and sends initial NAS message.
If resource indication information comprises UL grant information and the 2nd UL grant information, the resource of message transmission module 210 by first sub-frame of uplink of the UL grant information in resource indication information indication sends RRC and connects and set up request message, and the resource of second sub-frame of uplink by the indication of the 2nd UL grant information in the resource indication information sends initial NAS message.
In specific implementation process, receive the message resource indication information after, sending module 210 can be with an immediate sub-frame of uplink after first sub-frame of uplink as second sub-frame of uplink.
If the message resource indication information (promptly comprises a UL grant information except comprising UL grant information, perhaps comprise UL grant information and the 2nd UL grant information), also comprise the subframe indication information, then message transmission module 210 is determined second sub-frame of uplink according to the subframe indication information in the resource indication information of receiving.
Wherein, if network side adopts the PDCCH schedule information to indicate, then receiver module 200 can be received twice resource indication information from network side; Accordingly, message transmission module 210 is set up request message by the resource transmission RRC connection of first sub-frame of uplink of UL grant information indication in the resource indication information, and sends initial NAS message by the resource of second sub-frame of uplink of PDCCH schedule information indication in the resource indication information.
In specific implementation process, message transmission module 210 can also place SRB0 with initial NAS message, sends by the CCCH channel.
If message transmission module 210 determines that initial NAS message sends failure, initial NAS message can be placed the RRC connection setup complete message, send to network side.
Need to prove that the embodiment of the invention is not limited to initial NAS message is placed the RRC connection setup complete message, any message in setting up the RRC connection procedure can be carried initial NAS message.
As shown in Figure 5, the method for inventive embodiments message transmission comprises the following steps:
Wherein, initial NAS message comprises but not to be limited to a kind of in the following message:
NAS Service Request, NAS Attach and NAS Tracking Area Update etc.
Wherein, can further include after the step 502:
First sub-frame of uplink that step 503, user terminal are indicated by the resource indication information of receiving sends the RRC connection and sets up request message, and second sub-frame of uplink of indicating by the resource indication information of receiving sends initial NAS message.
In the step 501, network side is determined first sub-frame of uplink and second sub-frame of uplink after receiving from the Preamble sign indicating number of user terminal.
Concrete, user terminal is that inserting at random of purpose initiated under the idle state with initial access.
The MAC layer of user terminal is initiated random access procedure, according to the Msg3 size, Group A, GroupB and path loss information etc. are selected suitable Preamble group, picked at random Preamble in selected group sends Preamble on suitable Prach resource.
Especially, if user terminal is R10UE, can utilize methods such as special P reamble or Prach resource to inform that network side self is R10UE.
Wherein, it is multiple that first sub-frame of uplink that the network side basis is determined in the step 502 and second sub-frame of uplink determine that the mode of resource indication information has, and enumerates several below:
Mode one, be applicable to that the resource of distributing to user terminal in the resource of distributing to user terminal in first sub-frame of uplink and second sub-frame of uplink is identical.

Concrete, user terminal with first sub-frame of uplink after the Msg2 6ms that receives as the transmission upstream data moment (i.e. first sub-frame of uplink) that is the ULgrant appointment.
For mode one, can adopt the position of implicit expression notice or explicit notification mode informing user terminal 20 second sub-frame of uplink.
The implicit expression advice method can be stipulated in agreement in advance, as long as then user terminal is received accidental access response message in the step 503, and after having determined first sub-frame of uplink according to accidental access response message, with an immediate sub-frame of uplink after first sub-frame of uplink as second sub-frame of uplink.Continuous two sub-frame of uplink that promptly use the Msg3 subframe to begin send RRC message and initial NAS message respectively.
The explicit notification mode can be by the position of network side informing user terminal second sub-frame of uplink.Concrete, network side as resource indication information, is used for the subframe indication information indicating user terminal and determines second sub-frame of uplink according to the subframe indication information in the step 502; Accordingly, user terminal just can be determined second sub-frame of uplink according to the subframe indication information in the step 503.
The subframe indication information can be to be used for distinguishing a frame or two frames, can only represent with 0 or 1; Such as 0 expression conventional allocation mode (being only to distribute a sub-frame of uplink resource in the accidental access response in order to transmission Msg3), continuous two sub-frame of uplink that 1 expression uses the Msg3 subframe to begin send RRC message and initial NAS message respectively; Then user terminal is after receiving 1, with an immediate sub-frame of uplink after first sub-frame of uplink as second sub-frame of uplink.
The subframe indication information can also be represented the position of second sub-frame of uplink, such as 3, represents that then the 3rd sub-frame of uplink is second sub-frame of uplink after first sub-frame of uplink.
In specific implementation process, network side determines that user terminal is the surplus yield of R10UE or network side during greater than threshold value, can be set to 1 by the subframe indication information.
The subframe indication information can adopt the 1bit R in the MAC RAR form to indicate, and also can indicate with other modes.
Mode two, be applicable to that the resource of distributing to user terminal in the resource of distributing to user terminal in first sub-frame of uplink and second sub-frame of uplink is different.
In the step 502, network side in first sub-frame of uplink, distribute to distribute to user terminal in the resource of user terminal and second sub-frame of uplink resource not simultaneously, ULgrant information with the resource correspondence of first sub-frame of uplink, and the 2nd UL grant information of the resource correspondence of second sub-frame of uplink sends to user terminal as resource indication information;
Accordingly, in the step 503, the resource of user terminal by first sub-frame of uplink of UL grant information indication sends RRC and connects and set up request message, and the resource of second sub-frame of uplink by the indication of the 2nd UL grant information sends initial NAS message.
Because it is different to distribute to the resource of user terminal in the resource of distributing to user terminal in first sub-frame of uplink and second sub-frame of uplink, so two UL grant information all need be sent to user terminal.
In specific implementation process, can expand the resource of corresponding first sub-frame of uplink in first UL grant territory, the resource of second corresponding second sub-frame of uplink in UL grant territory to UL grant territory.
In the step 502, network side can send accidental access response message to user terminal in the Msg2 window, wherein comprise UL grant information and the 2nd UL grant information; In the step 503, after the MAC layer of user terminal receives accidental access response message, on corresponding resource, sending Msg3 (promptly comprise RRC and is connected the message of setting up request message) and initial NAS message according to the indication of UL grant information and the 2nd UL grant information.
For mode two, can adopt the position of implicit expression notice or explicit notification mode informing user terminal second sub-frame of uplink.
In the mode two in implicit expression notice and explicit notification side and the mode one implicit expression notify identically with the explicit notification mode, do not repeat them here.
Mode three, employing PDCCH schedule information mode.
In the step 502, network side with the UL grant information of the resource correspondence of first sub-frame of uplink as resource indication information, after user terminal sends, with the physical downlink control channel PDCCH schedule information as resource indication information, send to user terminal, wherein the PDCCH schedule information is used to indicate second sub-frame of uplink of distributing to user terminal, and the resource of second sub-frame of uplink;
Accordingly, the resource of user terminal by first sub-frame of uplink of UL grant information indication sends RRC and connects and set up request message in the step 503, and the resource of second sub-frame of uplink by the indication of PDCCH schedule information sends initial NAS message.
Concrete, the moment that network side sends PDCCH need guarantee that second sub-frame of uplink is positioned at after first sub-frame of uplink, and is positioned at before the RRC connection foundation request, the resource of PDCCH indication can be distributed by existing dispatching algorithm;
Accordingly, user terminal is received PDCCH, and first sub-frame of uplink after 4ms (i.e. second sub-frame of uplink) sends data according to the resource of PDCCH indication.
In the step 502, network side can send accidental access response message to user terminal in the Msg2 window, wherein comprise UL grant information, supposes that the moment of transmission accidental access response message is t;
Network side at least after the 3ms, sends the PDCCH schedule information, i.e. delivery time 〉=t+3 after Msg2 sends;
In the step 503, after the MAC layer of user terminal received accidental access response message, the indication according to UL grant information after 6ms sent Msg3 on corresponding resource, i.e. delivery time=t+6;
User terminal is after receiving the PDCCH scheduling message, and the resource of indicating according to the PDCCH schedule information sends initial NAS message, promptly sends the initial NAS message of the RRC connection setup complete message moment 〉=transmission moment 〉=t+7.
Wherein, user terminal can place SRB0 with initial NAS message, sends by the CCCH channel.
Accordingly, in the message of CCCH carrying, need to increase initial NAS message, specifically referring to table 1.
Initial NAS message definition mode and identical in initial NAS message definition mode and the system that embodiment of the invention message sends does not repeat them here.
If the RRC connection is set up request message and all sent by CCCH with initial these two signalings of NAS message, because the transmission mode of RLC is TM, TM does not have the function that reorders, and can take following method to solve if these two message appearance are out of order with losing:
At the MAC layer these two message are reordered.
The MAC layer of network side is known two signalings running time-frequency resource and progress information separately, can introduce particular processing to the reception of these two message, guarantees to submit according to the order of sequence.For example, when request message is set up in the RRC connection also less than correct the reception, if initial NAS message is correctly received, then carry out buffer memory at the MAC layer, connect until RRC and to set up request message and receive again two message are forwarded to high level according to the order of sequence, the perhaps RRC transmission of messages failure NAS message of then deleting buffer memory is thought procedure failure.
Concrete, can further include after the step 503:
Step a504, network side were received initial NAS message, the initial NAS message that buffer memory is received before receiving that request message is set up in the RRC connection;
After receiving that request message is set up in the RRC connection, connect initial NAS message and the user terminal of setting up request message and buffer memory according to RRC and connect; Or do not receive that in setting-up time RRC connects when setting up request message, the initial NAS message of deletion buffer memory.
At rrc layer these two message are handled.
If the rrc layer of network side has been received initial NAS message earlier, then set up MME and be connected (promptly send to MME, make MME initiate to set up process) with user terminal 20, treat that RRC connects to set up request message and receive, begin to set up RRC again and connect.Set up the request message failure if follow-up RRC connects, then delete MME and connect.
Concrete, can further include after the step 503:
Step b504, network side were received initial NAS message before receiving that request message is set up in the RRC connection, set up MME according to initial NAS message with user terminal and be connected;
Receive RRC connect set up request message after, connect according to RRC and to set up request message and set up RRC with user terminal and be connected; Or not receiving that in setting-up time RRC connects when setting up request message, the MME that deletion is set up connects.
If initial NAS message sends failure, the embodiment of the invention also provides a kind of re-transmission scheme.Can further include after the step 503:
If user terminal is determined initial NAS message and is sent failure, initial NAS message can be placed the RRC connection setup complete message, send to network side.
After determining that according to the ACK/NACK feedback initial NAS message sends failure such as the MAC layer of user terminal, can report to the rrc layer of user terminal, the rrc layer of user terminal places the RRC connection setup complete message with initial NAS message, sends to network side.
Need to prove that the embodiment of the invention is not limited to initial NAS message is placed the RRC connection setup complete message, any message in setting up the RRC connection procedure can be carried initial NAS message.
From the foregoing description as can be seen: embodiment of the invention network side is identified for carrying radio resource control RRC and connects first sub-frame of uplink of setting up request message and be used to carry second sub-frame of uplink of initial non access stratum NAS message, and wherein said second sub-frame of uplink is a sub-frame of uplink before the sub-frame of uplink of carrying RRC connection setup complete message; Described network side is determined resource indication information according to described first sub-frame of uplink and described second sub-frame of uplink determined, and send described resource indication information to user terminal, be used to indicate described user terminal to set up request message, and send initial NAS message by described second sub-frame of uplink of described resource indication information indication by described first sub-frame of uplink transmission RRC connection of described resource indication information indication.
