Carry out transfer of data by IP link and L1/L2 (1/ layer 2 on layer is as E1, optical fiber/ATM, 802.3 etc.) layer between ENB and the CPS.
Describe as can be known as above-mentioned E1 interface, ENB has part RRC function, can identification control plane signaling and user face data by Upper ARQ or MAC layer.Can discern by the message identifier of RRC is Lower RRC message or Upper RRC message.For Upper RRC message, then message is encapsulated in the ENBAP message of CO protocol carrying and on IP, transmits.For NAS message, ENB with it as Upper RRC (ENB can not discern its for NAS message) message.
Form logic interfacing E2 by E1 interface and E3 interface, be used to represent that UE is connected with the RRC of network.
Sending a Upper RRC message with UE to network below is example, and three network node entities being connected with the E3 interface by E1 interface handling process to this Upper RRC message is described below:
The Upper rrc layer of UE side adds that with Upper RRC message agreement packet header (as sign) passes to the lower of lower floor rrc layer then; The lower rrc layer is done this layer processing equally, and (Service Data Unit SDU), adds the packet header of this layer etc. then, passes to the UpperARQ of lower floor as service data unit with the data that receive; Upper ARQ does this layer processing equally, as segmentation, Flow Control, add this layer information and pass to the MAC layer, transmission may be the later packet of segmentation; MAC layer processing such as the MAC layer works as dispatcher add that this layer information sends physical layer to; Physical layer is carried out physical layer process with the data of receiving, as chnnel coding, and spread spectrum, modulation sends data eating dishes without rice or wine.
The physical layer of network side ENB is come out data demodulates by physical layer operations such as demodulation, despreading and channel-decodings, passes to upper strata MAC layer; The MAC layer is handled the header packet information of MAC layer wherein according to the data received, and remaining UpperARQ data are sent to upper strata UpperARQ; If the UpperARQ layer of UE side has carried out segment processing, then all segment datas are collected together at the UpperARQ of ENB layer, send to upper strata lower RRC then; It is Upper RRC that lower RRC on ENB goes out this message according to the information Recognition of this layer, then message is encapsulated in the ENBAP message of CO protocol carrying and on IP, transmits, by and CPS between the E3 interface, handle at last by the Upper RRC that E3 interface protocal layers arrive CPS in the CPS side.
The E3 interface also transmits the control signaling between ENB and the CPS, similar NodeB application protocol of the prior art (NodeB Application Protocol, NBAP) interface function.CPS can control ENB by the ENBAP signaling, and ENBAP can distinguish each user on connection-oriented signaling bear, can carry out configuration on the ENB to each user.
