Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 2, the system that embodiment of the present invention message sends comprises: network equipment 10 and user terminal 20.
Wherein, initial NAS message comprises but not to be limited to a kind of in 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 Preamble code to network equipment 10, and network equipment 10 is being received Preamble code definite the first sub-frame of uplink and the second sub-frame of uplink afterwards.
Concrete, user terminal 20 be take the random access initially accessing as object and is initiated under idle state.
The MAC of user terminal 20 (Media Access Control, media access control) layer initiating random access procedure, according to Msg (message) 3 sizes, Group A, Group B and path loss information etc. are selected suitable Preamble group, in selected group, choose at random Preamble, at the upper Preamble that sends of suitable Prach (Physical Random Access Channel).
Especially, if user terminal 20 is R10UE, can utilize the methods such as special Preamble or Prach resource to inform that network equipment 10 self is R10UE.
Wherein, it is multiple that the first sub-frame of uplink that network equipment 10 bases are determined and the second sub-frame of uplink determine that the mode of resource indication information has, and enumerates several below:
Mode one, the resource that is applicable to distribute in the first sub-frame of uplink user terminal 20 are identical with the resource of distributing to user terminal 20 in the second sub-frame of uplink.
In specific implementation process, network equipment 10 is distributed to the resource of user terminal 20 when identical with the resource of distributing to user terminal 20 in the second sub-frame of uplink in the first sub-frame of uplink, using UL grant corresponding to identical resource (ascending resource distribution) information as resource indication information.
Accordingly, user terminal 20 is set up request message by the resource transmission RRC connection of the first sub-frame of uplink of UL grant information indication, and the resource of second sub-frame of uplink of indicating by UL grant information sends initial NAS message.
Owing to distributing in the first sub-frame of uplink, the resource of user terminal 20 is identical with the resource of distributing to user terminal 20 in the second sub-frame of uplink, so only need a UL grant information.
In specific implementation process, network equipment 10 can send accidental access response message to user terminal 20 in Msg2 window, wherein comprises UL grant information; The MAC layer of user terminal 20 receives after accidental access response message, sends Msg3 (comprise RRC and connect the message of setting up request message) and initial NAS message according to the indication of UL grant information in corresponding resource.
Concrete, user terminal 20 first sub-frame of uplink after the Msg26ms receiving is as the transmission upstream data moment (i.e. the 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.
Implicit expression advice method can be stipulated in advance in agreement, as long as user terminal 20 is received accidental access response message, and determined after the first sub-frame of uplink according to accidental access response message, after the first sub-frame of uplink, an immediate sub-frame of uplink is as the second sub-frame of uplink.Use continuous two sub-frame of uplink that Msg3 subframe starts to send respectively RRC message and initial NAS message.
Explicit notification mode can be by the position of network equipment 10 informing user terminal 20 second sub-frame of uplink.Concrete, network equipment 10, using subframe indication information as resource indication information, is used to indicate user terminal 20 and determines the second sub-frame of uplink according to subframe indication information; Accordingly, user terminal 20 just can be determined the second sub-frame of uplink according to subframe indication information.
Subframe indication information can be for distinguishing a frame or two frames, can only with 0 or 1, represent; Such as 0 expression conventional allocation mode (being only to distribute a sub-frame of uplink resource in accidental access response in order to transmit Msg3), 1 represents that continuous two sub-frame of uplink that use Msg3 subframe to start send respectively RRC message and initial NAS message; User terminal 20 is after receiving 1, and after the first sub-frame of uplink, an immediate sub-frame of uplink is as the second sub-frame of uplink.
Subframe indication information can also represent the position of the second sub-frame of uplink, such as 3, represents after the first sub-frame of uplink that the 3rd sub-frame of uplink is the second sub-frame of uplink.
Subframe indication information can adopt the 1bit R in MAC RAR (MAC accidental access response) form to indicate, and also can indicate by other modes.
Mode two, the resource that is applicable to distribute in the first sub-frame of uplink user terminal 20 are different with the resource of distributing to user terminal 20 in the second sub-frame of uplink.
In specific implementation process, network equipment 10 is distributed to the resource of user terminal 20 when different with the resource of distributing to user terminal 20 in the second sub-frame of uplink in the first sub-frame of uplink, by a UL grant information corresponding to the resource of the first sub-frame of uplink, and the 2nd ULgrant information corresponding to the resource of the second sub-frame of uplink is as resource indication information, to user terminal, sends.
Accordingly, user terminal 20 is set up request message by the resource transmission RRC connection of the first sub-frame of uplink of a UL grant information indication, and the resource of second sub-frame of uplink of indicating by the 2nd UL grant information sends initial NAS message.
Owing to distributing in the first sub-frame of uplink, the resource of user terminal 20 is different with the resource of distributing to user terminal 20 in the second sub-frame of uplink, so two UL grant information all need to be sent to user terminal 20.
In specific implementation process, can expand to UL grant territory the resource of corresponding the first sub-frame of uplink in first UL grant territory, the resource of second corresponding the second sub-frame of uplink in 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 mode two, implicit expression notice is identical with explicit notification mode with implicit expression notice in mode one with explicit notification side, does not repeat them here.
Mode three, employing PDCCH (physical downlink control channel, Physical Downlink Control Channel) schedule information mode.
Accordingly, user terminal 20 is set up request message by the resource transmission RRC connection of the first sub-frame of uplink of UL grant information indication, and the resource of second sub-frame of uplink of indicating by PDCCH schedule information sends initial NAS message.
Concrete, after the moment that network equipment 10 sends PDCCH need guarantee that the second sub-frame of uplink is positioned at the first sub-frame of uplink, and be positioned at before RRC connects the request of foundation, 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. the 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 Msg2 window, wherein comprises UL grant information, supposes that the moment of transmission accidental access response message is t;
The MAC layer of user terminal 20 receives after accidental access response message, sends Msg3, i.e. delivery time=t+6 after 6ms according to the indication of ULgrant information in corresponding resource;
Wherein, user terminal 20 can be placed in initial NAS message in SRB (Signal Radio Bear, Signaling Radio Bearer) 0, by CCCH (Common Control Channel, Common Control Channel) channel, sends.
Accordingly, in the message of CCCH carrying, need to increase initial NAS message, specifically referring to table 1:
| --ASN1START UL-CCCH-Message::＝SEQUENCE{ message UL-CCCH-MessageType } UL-CCCH-MessageType::＝CHOICE{ c1 CHOICE{ rrcConnectionReestablishmentRequest RRCConnectionReestablishmentRequest， rrcConnectionRequest RRCConnectionRequest， }， messageClassExtension-v10 CHOICE{ c2 CHOICE{ ulInformationTransferCCCH ULInformationTransferCCCH }， messageClassExtension SEQUENCE{} } } --ASN1Stop |
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
| --ASN1START ULInformationTransferCCCH::＝ SEQUENCE{ criticalExtensions CHOICE{ c1 CHOICE{ ulInformationTransferCCCH ULInformationTransferCCCH-IEs， spare3NULL，spare2NULL，spare1 NULL }， criticalExtensionsFuture SEQUENCE{} } } ULInformationTransferCCCH-IEs::＝SEQUENCE{ dedicatedInfoNAS DedicatedInfoNAS， nonCriticalExtension SEQUENCE{} OPTIONAL } --ASN1Stop |
Table 2UL Information Transfer CCCH message (at the NAS of CCCH channel message format).
If request message is set up in RRC connection and initial these two signalings of NAS message all send by CCCH, due to RLC (Radio Link Control, wireless link control) transmission mode is TM (TransparentMode, transparent mode), TM does not have the function reordering, if these two message occur out of order and lose and can take following method to solve:
At 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 special 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 RRC connection also less than correct reception, if initial NAS message is correctly received, at MAC layer, carry out buffer memory, until RRC connects and to set up request message and receive two message are forwarded to high level according to the order of sequence, or the NAS message that buffer memory is deleted in RRC transmission of messages failure, thinks procedure failure.
Concrete, network equipment 10, before receiving that request message is set up in RRC connection, is received initial NAS message, the initial NAS message that buffer memory is received;
Set up after request message receiving that RRC connects, according to RRC, to connect initial NAS message and the user terminal 20 of setting up request message and buffer memory and connect; Or in setting-up time, do not receive that RRC connects while setting up request message, deletes the initial NAS message of buffer memory.
At rrc layer, these two message are processed.
If the rrc layer of network equipment 10 has first been received initial NAS message, set up MME with user terminal 20 and be connected (send to MME, make MME initiate process of establishing), treat that RRC connects to set up request message and receive, then start to set up RRC and connect.If follow-up RRC connects, set up request message failure, delete MME and connect.
Concrete, network equipment 10, before receiving that request message is set up in RRC connection, is received initial NAS message, sets up MME be connected according to initial NAS message with user terminal 20;
Set up after request message receiving that RRC connects, according to RRC, to connect and set up request message and set up RRC with user terminal 20 and be connected; Or in setting-up time, do not receive that RRC connects while setting up request message, delete the MME setting up and connect.
If initial NAS message sends unsuccessfully, the embodiment of the present invention also provides a kind of re-transmission scheme:
If user terminal 20 determines that initial NAS message sends unsuccessfully, initial NAS message can be placed in to RRC connection setup complete message, to network equipment 10, send.
Such as after the MAC layer of user terminal 20 determines that according to ACK/NACK feedback initial NAS message sends unsuccessfully, can report to the rrc layer of user terminal 20, the rrc layer of user terminal 20 is placed in RRC connection setup complete message by initial NAS message, to network equipment 10, sends.
Wherein, the network equipment of the embodiment of the present invention can be base station, can be also other equipment of network side, can also be the equipment that network side is new.
As shown in Figure 3A, embodiment of the present invention the first network equipment comprises: subframe determination module 100 and information sending module 110.
In specific implementation process, subframe determination module 100 can be determined the first sub-frame of uplink and the second sub-frame of uplink afterwards receiving from the Preamble code of user terminal.
Wherein, it is multiple that the first sub-frame of uplink that information sending module 110 bases are determined and the second sub-frame of uplink determine that the mode of resource indication information has, and enumerates several below:
Mode one, the resource that is applicable to distribute in the first sub-frame of uplink user terminal are identical with the resource of distributing to user terminal in the second sub-frame of uplink.
For mode one, can adopt the position of implicit expression notice or explicit notification mode informing user terminal 20 second sub-frame of uplink.
Implicit expression advice method can be stipulated in advance in agreement, as long as user terminal is received accidental access response message, and determined after the first sub-frame of uplink according to accidental access response message, after the first sub-frame of uplink, an immediate sub-frame of uplink is as the second sub-frame of uplink.
Explicit notification mode can, by information sending module 110 using subframe indication information as resource indication information, be used to indicate user terminal and determine the second sub-frame of uplink according to subframe indication information.
Mode two, the resource that is applicable to distribute in the first sub-frame of uplink user terminal are different with the resource of distributing to user terminal in the second sub-frame of uplink.
In specific implementation process, information sending module 110 is by a UL grant information corresponding to the resource of the first sub-frame of uplink, and the 2nd UL grant information corresponding to the resource of the second sub-frame of uplink is as resource indication information, to user terminal, send, wherein a UL grant information is used to indicate the resource of the first sub-frame of uplink of distributing to user terminal, and the 2nd UL grant information is used to indicate the resource of the 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 mode two, implicit expression notice is identical with explicit notification mode with implicit expression notice in mode one with explicit notification side, does not repeat them here.
Mode three, employing PDCCH schedule information mode.
If request message is set up in 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 reordering, if out of order and loss appears in these two message, also needs to carry out respective handling, specifically has two schemes:

Accordingly, in step 503, user terminal is set up request message by the resource transmission RRC connection of the first sub-frame of uplink of UL grant information indication, and the resource of second sub-frame of uplink of indicating by UL grant information sends initial NAS message.
Owing to distributing in the first sub-frame of uplink, the resource of user terminal is identical with the resource of distributing to user terminal in the second sub-frame of uplink, so only need a UL grant information.
In step 502, network side can send accidental access response message to user terminal in Msg2 window, wherein comprises UL grant information; In step 503, the MAC layer of user terminal receives after accidental access response message, sends Msg3 (comprise RRC and connect the message of setting up request message) and initial NAS message according to the indication of UL grant information in corresponding resource.
Concrete, user terminal first sub-frame of uplink after the Msg2 6ms receiving is as the transmission upstream data moment (i.e. the first sub-frame of uplink) that is 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.
Implicit expression advice method can be stipulated in advance in agreement, as long as in step 503, user terminal is received accidental access response message, and determined after the first sub-frame of uplink according to accidental access response message, after the first sub-frame of uplink, an immediate sub-frame of uplink is as the second sub-frame of uplink.Use continuous two sub-frame of uplink that Msg3 subframe starts to send respectively RRC message and initial NAS message.
Explicit notification mode can be by the position of network side informing user terminal the second sub-frame of uplink.Concrete, in step 502, network side, using subframe indication information as resource indication information, is used to indicate user terminal and determines the second sub-frame of uplink according to subframe indication information; Accordingly, in step 503, user terminal just can be determined the second sub-frame of uplink according to subframe indication information.
Subframe indication information can be for distinguishing a frame or two frames, can only with 0 or 1, represent; Such as 0 expression conventional allocation mode (being only to distribute a sub-frame of uplink resource in accidental access response in order to transmit Msg3), 1 represents that continuous two sub-frame of uplink that use Msg3 subframe to start send respectively RRC message and initial NAS message; User terminal is after receiving 1, and after the first sub-frame of uplink, an immediate sub-frame of uplink is as the second sub-frame of uplink.
Subframe indication information can also represent the position of the second sub-frame of uplink, such as 3, represents after the first sub-frame of uplink that the 3rd sub-frame of uplink is the second sub-frame of uplink.
In specific implementation process, network side determines that user terminal is the surplus yield of R10UE or network side while being greater than threshold value, can be set to 1 by subframe indication information.
Subframe indication information can adopt the 1bit R in MAC RAR form to indicate, and also can indicate by other modes.
Mode two, the resource that is applicable to distribute in the first sub-frame of uplink user terminal are different with the resource of distributing to user terminal in the second sub-frame of uplink.
In step 502, network side is distributed to the resource of user terminal when different with the resource of distributing to user terminal in the second sub-frame of uplink in the first sub-frame of uplink, by a ULgrant information corresponding to the resource of the first sub-frame of uplink, and the 2nd UL grant information corresponding to the resource of the second sub-frame of uplink is as resource indication information, to user terminal, sends;
Accordingly, in step 503, user terminal is set up request message by the resource transmission RRC connection of the first sub-frame of uplink of a UL grant information indication, and the resource of second sub-frame of uplink of indicating by the 2nd UL grant information sends initial NAS message.
Owing to distributing in the first sub-frame of uplink, the resource of user terminal is different with the resource of distributing to user terminal in the second sub-frame of uplink, so two UL grant information all need to be sent to user terminal.
In specific implementation process, can expand to UL grant territory the resource of corresponding the first sub-frame of uplink in first UL grant territory, the resource of second corresponding the second sub-frame of uplink in UL grant territory.
In step 502, network side can send accidental access response message to user terminal in Msg2 window, wherein comprises a UL grant information and the 2nd UL grant information; In step 503, the MAC layer of user terminal receives after accidental access response message, sends Msg3 (comprise RRC and be connected the message of setting up request message) and initial NAS message according to the indication of a UL grant information and the 2nd UL grant information in corresponding resource.
For mode two, can adopt the position of implicit expression notice or explicit notification mode informing user terminal the second sub-frame of uplink.
In mode two, implicit expression notice is identical with explicit notification mode with implicit expression notice in mode one with explicit notification side, does not repeat them here.
Mode three, employing PDCCH schedule information mode.
In step 502, network side is using UL grant information corresponding to the resource of the first sub-frame of uplink as resource indication information, after sending to user terminal, using physical downlink control channel PDCCH schedule information as resource indication information, to user terminal, send, wherein PDCCH schedule information is used to indicate the second sub-frame of uplink of distributing to user terminal, and the resource of the second sub-frame of uplink;
Accordingly, in step 503, user terminal is set up request message by the resource transmission RRC connection of the first sub-frame of uplink of UL grant information indication, and the resource of second sub-frame of uplink of indicating by PDCCH schedule information sends initial NAS message.
Concrete, after the moment that network side sends PDCCH need guarantee that the second sub-frame of uplink is positioned at the first sub-frame of uplink, and be positioned at before RRC connects the request of foundation, 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. the second sub-frame of uplink) sends data according to the resource of PDCCH indication.
In step 502, network side can send accidental access response message to user terminal in Msg2 window, wherein comprises UL grant information, supposes that the moment of transmission accidental access response message is t;
Network side at least after 3ms, sends PDCCH schedule information, i.e. delivery time >=t+3 after Msg2 sends;
In step 503, the MAC layer of user terminal receives after accidental access response message, sends Msg3, i.e. delivery time=t+6 after 6ms according to the indication of UL grant information in corresponding resource;
User terminal, after receiving PDCCH scheduling message, sends initial NAS message according to the resource of PDCCH schedule information indication, send RRC connection setup complete message constantly >=send the initial NAS message moment >=t+7.
Wherein, user terminal can be placed in SRB0 by initial NAS message, by CCCH channel, sends.
Accordingly, in the message of CCCH carrying, need to increase initial NAS message, specifically referring to table 1.
In the system that initial NAS message definition mode sends with embodiment of the present invention message, initial NAS message definition mode and identical, does not repeat them here.
If RRC connects and to set up request message 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 reordering, if these two message occur out of order and lose and can take following method to solve:
At 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 special 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 RRC connection also less than correct reception, if initial NAS message is correctly received, at MAC layer, carry out buffer memory, until RRC connects and to set up request message and receive two message are forwarded to high level according to the order of sequence, or the NAS message that buffer memory is deleted in RRC transmission of messages failure, thinks procedure failure.
Concrete, after step 503, can further include:
Step a504, network side, before receiving that request message is set up in RRC connection, are received initial NAS message, the initial NAS message that buffer memory is received;
Set up after request message receiving that RRC connects, according to RRC, to connect initial NAS message and the user terminal of setting up request message and buffer memory and connect; Or in setting-up time, do not receive that RRC connects while setting up request message, deletes the initial NAS message of buffer memory.
At rrc layer, these two message are processed.
If the rrc layer of network side has first been received initial NAS message, set up MME with user terminal 20 and be connected (send to MME, make MME initiate process of establishing), treat that RRC connects to set up request message and receive, then start to set up RRC and connect.If follow-up RRC connects, set up request message failure, delete MME and connect.
Concrete, after step 503, can further include:
Step b504, network side, before receiving that request message is set up in RRC connection, are received initial NAS message, set up MME be connected according to initial NAS message with user terminal;
Set up after request message receiving that RRC connects, according to RRC, to connect and set up request message and set up RRC with user terminal and be connected; Or in setting-up time, do not receive that RRC connects while setting up request message, delete the MME setting up and connect.
If initial NAS message sends unsuccessfully, the embodiment of the present invention also provides a kind of re-transmission scheme.After step 503, can further include:
If user terminal is determined initial NAS message and is sent unsuccessfully, initial NAS message can be placed in to RRC connection setup complete message, to network side, send.
Such as after the MAC layer of user terminal determines that according to ACK/NACK feedback initial NAS message sends unsuccessfully, can report to the rrc layer of user terminal, the rrc layer of user terminal is placed in RRC connection setup complete message by initial NAS message, to network side, sends.
It should be noted that, the embodiment of the present invention is not limited to initial NAS message is placed in to RRC connection setup complete message, and any message in setting up RRC connection procedure can be carried initial NAS message.
