Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1, a flowchart illustrating steps of a method for implementing data transmission according to an embodiment of the present invention is shown, which may specifically include the following steps:
step 110: setting and starting a plurality of GE transmission interfaces;
specifically, a plurality of GE transmission interfaces are set and started in a transmission control device in the eNodeB; it should be noted that, in order to be fused with the existing eNodeB to the greatest extent, the present embodiment proposes to provide two external GE transmission interfaces and two internal GE transmission interfaces, that is, two GE transmission interfaces are provided for the transmission between the eNodeB and the external network element, and two GE transmission interfaces are also provided between the internal and baseband processors through the NP chip. Therefore, the external traffic aggregation and distribution of the eNodeB is realized through the link aggregation function of the two external GE transmission interfaces, the maximum aggregation transmission bandwidth supports 2Gbps, the two internal GE transmission interfaces ensure the uniform aggregation and distribution of the traffic through different control algorithms, and the transmission with each baseband processor is realized through the exchange chip.
Step 120: configuring a data stream distribution strategy;
it is to be noted that, in this embodiment, two GE transmission interfaces PORT0 and PORT1 may be set on the transmission main control board SCTE and simultaneously turned on, so as to implement a link aggregation function of the external 802.3ad in the standard protocol, and an OM (Operation Maintenance) entity configures the link aggregation control function. By the mode, the main control board NP chip can be a data high-speed forwarding channel, so that rule matching and forwarding of data can be realized, for example, specified fields can be matched, and a forwarding rule can be selected. Meanwhile, the NP chip also internally opens two transmission PORT PORTs and communicates with each baseband card through the Ethernet switch chip. In this embodiment, the eNodeB performs traffic aggregation and distribution on service or signaling data mainly by controlling the ingress and egress of packets from two different PORTs of the NP, and meets the standard protocol requirements between the external PORT and other external network elements, thereby ensuring that the two PORTs operate normally, and under abnormal conditions, there are related alarms and post-processing, and ensuring that no or few packets are lost as far as possible.
Specifically, the core of the eNodeB for implementing the distribution control of the data traffic is to implement the selection of the port according to a distribution policy, and although the standard protocol does not specify the distribution policy, any distribution policy needs to ensure that all frames constituting a service flow are transmitted on a link in the order of the transmitting end, and cannot be out of order or repeated; based on this, the present embodiment proposes to configure the data stream distribution policy by the following way, but is not limited to this:
A. based on the current transmission architecture of the eNodeB, establishing a mapping relation list between the data message and the GE transmission interface by using the parameter information carried by the data message; when an uplink data message or a downlink data message is received, inquiring the mapping relation list according to parameter information carried by the uplink data message or the downlink data message, and determining a GE transmission interface for sending the uplink data message or the downlink data message;
B. performing hash operation on the parameter information carried by the data message; establishing a mapping relation list of the hash operation value and the GE transmission interface; and when an uplink data message or a downlink data message is received, inquiring the mapping relation list according to the parameter information carried by the uplink data message or the downlink data message, and determining a GE transmission interface for sending the uplink data message or the downlink data message.
It should be noted that, in this embodiment, when the data flow distribution policy is configured in the a or B mode, the parameter information image carried in the data packet at least includes any one of the following parameters, but is not limited to this: the source or destination MAC address of the data packet ethernet frame, the source or destination IP address of the data packet, the source or destination port numbers of UDP, TCP, SCTP, and the TEID (Tunnel Endpoint ID) of the GTP-U packet.
Specifically, the GE transmission port for sending the message can be determined simply by using the above 4 kinds of message information: for example, if the MAC address of the message is 00:01:02:03:04:05, the corresponding GE transport interface is PORT 0; if the MAC address of the message is 00:21:22:23:24:25, the corresponding GE transmission interface is PORT 1; that is, the mapping between the MAC address, IP or port number and the GE transmission interface is established, and the NP chip can determine the GE transmission interface for sending the packet through the mapping relationship; for example, by using the information such as MAC, IP, port number, TEID, etc., a hash algorithm is used to perform an xor or other hash operation on the source MAC and the destination MAC address of the packet to obtain a hash value, and a mapping relationship is established between the hash value and the GE transmission interface.
C. In addition, in order to meet the requirement of maintaining the frame order, it is necessary to ensure that all frames on the same SCTP link, GTP-U link, or OM channel of the eNodeB are sent in sequence. The present embodiment provides a method for configuring a data stream distribution policy based on different baseband boards, cells, or bearers for distributing data traffic to a specified GE transmission interface, which specifically includes: receiving a system data stream distribution rule configured by an upper entity and forwarding the system data stream distribution rule to a baseband processor; setting an uplink external GE transmission interface and a downlink internal GE transmission interface corresponding to system data by using the data stream distribution rule; and after the baseband processor establishes a GTP-U link corresponding to the system data according to the system data flow distribution rule, acquiring uplink internal GE transmission interface information set by the baseband processor according to a target MAC address of the GTP-U message. The system data at least comprises one of different baseband processing board card data, different cell data and load-bearing data corresponding to different QCI values.
The OM, HL, BPOG PDCP and SCTDD system modules of the eNodeB are taken as an example for detailed description as follows:
(1) data distribution based on different baseband board cards:
a) the OM configures sending ports of different baseband processing board card data according to the planning and informs the HL;
b) after receiving the configuration of OM, HL calls the SCT DD interface to establish a corresponding NP flow rule and informs the BPOG PDCP of corresponding configuration information

d) and the BPOG PDCP establishes a corresponding GTP-U link according to the configuration information, and appoints the baseband board card to transmit to the internal PORT through which the SCT board card passes through by the target MAC of the GTP-U message.
(2) Data distribution based on different cells:
a) OM configures the sending port of data in different cells and informs HL according to the plan;
b) the HL receives the configuration of the OM, when the services of different cells are generated, the SCDD interface is called according to the planning to establish the corresponding NP FLOW, and the BPOG PDCP is informed of the corresponding configuration information;
c) SCT DD establishes corresponding FLOW rule through NP drive according to interface configuration of HL, specifies external transmission PORT of message and internal PORT which is transmitted from SCT board card to baseband board card and passes through
d) The BPOG PDCP establishes GTP-U links corresponding to different cell services according to the configuration information, and specifies a baseband board card to send to an internal PORT through which the SCT board card passes by through a target MAC of a GTP-U message;
(3) data distribution based on different bearers:
a) OM distinguishes the load-bearing business of different QCI values according to planning, appoints the sending port of the corresponding load-bearing data and notifies HL;
b) the HL receives the configuration of the OM, calls the SCT DD interface to establish corresponding NP FLOW according to the planning of different bearers and the TEID values of GTP-U messages of different bearer links, and informs the BPOG PDCP of corresponding configuration information;
c) according to the interface configuration of the HL, the SCT DD establishes a corresponding FLOW rule through the NP drive, distinguishes TEID values of different GTP-U messages, specifies an external PORT for sending the messages and an internal PORT for sending the SCT board to the baseband board to pass through;
d) and the BPOG PDCP establishes GTP-U links corresponding to different TEID values according to the configuration information, and appoints the baseband board card to transmit to the internal PORT through which the SCT board card passes by through the target MAC of the GTP-U message.
Step 130: and selecting the GE transmission interface to transmit the data message by using the data stream distribution strategy.
It should be noted that, in this embodiment, the GE transmission interface preferably includes at least two external transmission interfaces and two internal transmission interfaces; based on this, the embodiment proposes that when a downlink message sent by an external network element through an external GE transmission interface is received, an internal GE transmission interface is selected to send the downlink message by using the data stream distribution policy; and when receiving an uplink message sent by the baseband processor through the internal GE transmission interface, selecting an external GE transmission interface to send the uplink message by using the data stream distribution strategy.
