As shown in Figure 1, it is the schematic network structure of the business cross-layer optimizing based on big data operation, in CN (core Net) and the CU (centralized unit) and DU (distribution unit) of RAN (wireless access network) in increase separately big data computing module (BDC, Big Data Computing).CN includes MME (mobile management entity), S-GW (gateway), P-GW (packet data gateway) And BDC, wherein MME and S-GW can merge deployment.CU include rrc layer functional entity, SDAP (service data adapting protocol)/ PDCP layer function entity and BDC.Wherein, pass through NG interface (including NG-C (control plane) and NG-U (user face)) between CN and CU Logical interaction, is interacted between CU and DU by F1 interface (including F1-C (control plane) and F1-U (user face)).

When it is implemented, the interface between CU and DU is F1 interface, F1-C is based on SCTP/IP agreement, and F1-U is with regard to GTP-U/ The function of F1-C: udp protocol manages (establishing reset/error indication process), system message management, UE context on F1 interface Management, bearer management, RRC information transmission etc., F1-U function: user data transmission and flow control etc..

As shown in Fig. 2, the implementation process diagram of its service optimization method implemented for core-network side, may include following Step:

S21, business data packet packet header is obtained.

When it is implemented, CN can be obtained accordingly at upper layer (Upper layer) or low layer (Lower layer) IP data packet.CN can intercept the packet header of IP data packet when carrying out data-moving by the way.

S22, header packet information is extracted from the business data packet packet header.

S23, according to the header packet information of extraction and the signal deployment information of acquisition, determine QoS of survice parameter.

Wherein, signal deployment information may include that service bearer establishes signaling and reconfigures signaling etc., and the present invention is implemented Example is to this without limiting.CN determines QoS of survice parameter according to the signal deployment information of acquisition and the header packet information of extraction.

S24, the qos parameter determined is sent to CU.

When it is implemented, CN can obtain packet header according to following either type in step S31:

The first embodiment obtains business data packet, and the number of preset length is intercepted from the business data packet of acquisition According to packet packet header.

Preferably, in order to which the load for lowering data packet head interception can not be to the IP data more having in the embodiment of the present invention Packet carries out packet header interception, but is intercepted by the way of discrete.It, can be according to following either type in the embodiment of the present invention with regard to this Data intercept packet packet header:

Mode one obtains business data packet according to the preset interception period, and intercepts in advance from the business data packet of acquisition If the packet header of length.

Specifically, CN can intercept IP packet header as unit of the time.Such as setting certain time interval T, T can To be using 1ms as unit granularity, being also possible to other times unit is granularity.An IP data packet is intercepted every time T, CN Packet header.

Mode two obtains a business data packet at interval of the business data packet of preset quantity, and from the business number of acquisition According to the packet header for intercepting preset length in packet.

Specifically, CN can intercept IP packet header as unit of the number of IP data packet.Such as setting one Packet_Num thresholding, Packet_Num can be the number less than 10, be also possible to the number greater than 10.When it is implemented, Number of data packets counter can be set to start counting from 0, often receive Packet_Num data packet, then intercept an IP Packet, and resetting number of data packets counter is 0.

Mode three obtains a business data packet at interval of preset byte, and intercepts in advance from the business data packet of acquisition If the packet header of length.

Second of embodiment, the packet header that preset length is copied from the transmission buffer of business data packet.

Under this embodiment, CN can intercept the packet header of IP data packet " by the way ", i.e., not individually entire IP data packet From being copied in new caching in its normal transmission buffer, but certain length is copied directly from its normal transmission buffer IP packet header, this length can be set into fixed.Such as preceding 256bytes.Be possible in this way copy length be more than Actual head length, in this way will not analysis to IP packet header is influenced.

CN can parse layer 3 after the packet header for getting IP data packet, the various head information of layer 4 or even layer 7, then Analyze the various head information, including type of service, service provider mark, business self-demand information etc. extracted.For example, according to The L3/L4/ even mark of L7 in datagram header, can judge the type of business, for example be HTTP (hypertext transfer protocol) industry Business or FTP (File Transfer Protocol) business etc..CN generates the QoS of survice ginseng towards RAN according to the business head information of analysis Number, including QCI (service quality rating mark), ARP (distribution and reservation priority), GBR (guaranteeing bit rate) and AMBR are (poly- Close maximum bit rate), data transmission time intervals, longest that the maximum value and minimum value of propagation delay time, that is, data packet require and Minimum access net propagation delay time etc..

CN is sent to CU by NG interface after determining qos parameter, by the qos parameter determined.When it is implemented, CN can use the existing signaling of NG interface or newly-increased signaling carries the qos parameter.For example, utilizing the QoS of CN configuration CU The Interface Flowchart (NG QoS configuration) of parameter carries qos parameter；Or increase new NAS QoS configuration flow or The QoS configuration process that person increases NG-AP specifically can be directed to each QoS Flow (service quality service stream) or user Configuration.It can also configure when existing user's initial context is established or when updating context for example, available existing NG- AP process: 1, INITIAL CONTEXT SETUP REQUEST 2, UE CONTEXT MODIFICATION REQUEST, or Other available NGAP Signalling exchange processes, the embodiment of the present invention is to this without limiting.

CU, can be according to the qos parameter configuration wireless network side data transmission control received after receiving qos parameter Parameter processed, specifically, CU can configure QOS Flow or DRB.For example, CU can be according to QOS for QoS Flow Parameter selects corresponding DRB (wireless data carrying) for it.And for DRB: according to the data packet period, size, requirement caching Time selects the configuration of suitable HARQ (hybrid automatic repeat-request) process, the mode (asynchronous or synchronous) of HARQ, control letter The TTI (transmission intercal) that road is configured, eated dishes without rice or wine, for example, being configurable to 1ms or 0.2ms etc..

Further, after the completion of CU configures QOS Flow or DRB according to the qos parameter received, data are being carried out During transmitting-receiving, qos parameter adjustment information can also be fed back to CN according to the real-time data transmission state of wireless net side, so that CN adjusts the qos parameter of wireless net side according to real-time data transmission state dynamic.Based on this, the service optimization side that the side CN is implemented Method can also include step shown in Fig. 3:
