Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a data transmission method and a network node device.
Background
With the development of wireless communication networks, the research on the fifth-Generation communication technology (5th-Generation, 5G) has been started worldwide, and 5G is a communication with multi-technology convergence, and meets the requirements of wide data and connection services through technology alternation and innovation. In the standard conference, the third Generation Partnership Project (3 GPP) has established a research Project si (study item) for the 5G new air interface study. According to the division of the vertical scene by 5G, the 3GPP mainly performs research on a new air interface technology from three aspects, including: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc). In a 5G network, the network is densely deployed as a necessary choice, but the problems of site selection of base stations, backhaul of densely deployed cells, and the like all appear in a large number. In addition, the huge number of terminals may impose a heavy load on the core network. The terminal cell has the functions of both the terminal and the base station, and can better solve the problems. Therefore, a terminating Cell (T-SC) is proposed by the industry and is becoming a possible trend of the future mobile communication network development.
In the prior art, a T-SC serving as a data transfer node often simply integrates functions of a terminal and a base station, for example, in the T-SC, the T-SC data is transmitted to a mobile communication network node by simply integrating the functions of the base station in the terminal and by using a backhaul method of a macro network base station NB. From the performance perspective, the T-SC uses the wireless network as a backhaul, and Remote user Remote UE plane data connected to the T-SC, and the signaling plane data needs to be backhauled to a Serving GateWay (SGW) of the mobile communication network through the macro network wireless network. However, the bandwidth and stability provided by the wireless backhaul are difficult to guarantee, so that the throughput is limited, and the throughput of users accessing the T-SC is not high, thereby seriously affecting the QoS of the Remote UE.
Therefore, how to improve the throughput and robustness of T-SC becomes a hot spot of research.

The embodiment of the invention provides a data transmission method and network node equipment aiming at the problem that the throughput of a user accessing a terminal cell is not high due to the limitation of the throughput of the terminal cell.
Currently, 3GPP Rel-12 defines a connection for performing handover based on PDN granularity (MAPCON), where data of 3GPP and non-3GPP are aggregated in a PDN GateWay (PDN GateWay, PGW), and this scheme needs to perform network modification, requires that non-3GPP be connected to PGW through an evolved packet data GateWay (evolved packet data GateWay, ePDG)/GTP mobility management based on S2a interface (S2a-based mobility over GTP, saMog), and also needs to authorize and manage the non-3GPP network.
The embodiment of the invention can meet the data aggregation between the 3GPP and the non-3GPP by adding the aggregation network element outside the PGW, and meanwhile, the non-3GPP network can not be limited by an operator, does not influence the existing network equipment, and does not need to upgrade and reform the existing network. Specifically, the description may be made according to fig. 1, where fig. 1 is a networking diagram of data aggregation provided in an embodiment of the present invention, and as shown in fig. 1, the networking diagram provided in the implementation of the present invention includes a user equipment 11, a terminating cell 12, a base station 13, an evolved packet core EPC14, a Wi-Fi 15, an aggregation network element 16, and a server 17.
As shown in fig. 1, in an uplink direction, a aggregation network element 16 may obtain a first path of data and a second path of data sent by a terminating cell 12, where the first path of data and the second path of data are obtained by the terminating cell 12 after processing user data received from a user equipment 11, and after obtaining the first path of data and the second path of data, the aggregation network element 16 may aggregate the first path of data and the second path of data obtained from the terminating cell 12 according to a preset aggregation policy, and send the data obtained after aggregation to the server 17. In the downlink direction, the aggregation network element 16 may be data transmitted by the server 17, where the data is data transmitted by the server 17 to the user equipment 11, and after acquiring the data transmitted by the server 17, the aggregation network element 16 may split the data transmitted by the server 17 to the user equipment 11 into third data and fourth data according to a preset splitting policy, and send the third data and the fourth data acquired by splitting to the terminating cell 12, and then the terminating cell 12 distributes the data to the user equipment 11.
Referring to fig. 2, fig. 2 is a schematic flowchart of a data transmission method according to an embodiment of the present invention, and as shown in fig. 2, the data transmission method may be applied to a network node transmission device, where the network node transmission device may be an aggregation network element set in a network, the aggregation network element is set between a data gateway and a server, and the data transmission method is applied to a terminating cell to transmit uplink data to the server, where the method may include:
s201: and acquiring the first path of data and the second path of data sent by the terminal cell.
In the embodiment of the present invention, a network node device may obtain a first path of data and a second path of data sent by a terminating cell, where the first path of data and the second path of data are obtained by processing, by the terminating cell, user data received from a user equipment. It should be noted that the first path of data and the second path of data acquired by the network node device are obtained by splitting, by the terminating cell, the encapsulated data acquired from the user equipment according to a preset load sharing policy. The first path of data is transmitted from a 3GPP Network, the second path of data is transmitted from a non-3GPP Network, and the Network node may further acquire a preset load sharing policy transmitted by a terminating cell through a Software Defined Network (SDN), where the preset load sharing policy is a policy for splitting data acquired from a user equipment and encapsulated by the terminating cell; the SDN is a novel network innovation architecture and is an implementation mode of network virtualization, and the core technology OpenFlow separates a control plane and a data plane of network equipment, so that the flexible control of network flow is realized, and the network becomes more intelligent as a pipeline.
In an embodiment, the network node device may obtain, from a 3GPP network, a first path of data uploaded to a server by a user equipment through a terminating cell, may also obtain, from a non-3GPP network, a second path of data uploaded to the server by the user equipment through the terminating cell, and obtain, through an SDN network, a splitting policy that the terminating cell splits data uploaded to the server by the user equipment into the first path of data and the second path of data. The first path of data acquired by the network node device is data obtained by encapsulating a tunneling protocol GTP-U of a user plane, and the second path of data is data obtained by encapsulating a network protocol IP. For example, assuming that a terminating cell acquires user data uploaded to a server by two user equipments, the terminating cell may split the user data into a first path of data obtained by GTP-U protocol encapsulation and a second path of data obtained by IP protocol encapsulation, send the first path of data to an aggregation network element (network node equipment) through a 3GPP network, and send the second path of data to the aggregation network element through non-3GPP, so that the aggregation network element (network node equipment) may acquire the first path of data and the second path of data sent by the terminating cell. It can be seen that this implementation of the embodiments of the present invention can increase the throughput of the terminating cell.

In the embodiment of the present invention, the network node device may aggregate the first path of data and the second path of data acquired from the terminating cell according to a preset aggregation policy. The preset aggregation strategy corresponds to a splitting strategy for splitting data uploaded to a server by user equipment into a first path of data and a second path of data by a terminal cell acquired through an SDN network. For example, assuming that a terminating cell acquires user data uploaded to a server by two user equipments, the terminating cell may split the user data into a first path of data obtained by GTP-U protocol encapsulation and a second path of data obtained by IP protocol encapsulation, send the first path of data to an aggregation network element (network node equipment) through a 3GPP network, and send the second path of data to the aggregation network element through a non-3GPP network, so that the aggregation network element (network node equipment) may acquire the first path of data and the second path of data sent by the terminating cell, and aggregate the first path of data and the second path of data according to a preset aggregation policy.
S203: and sending the data obtained after aggregation to a server.

S302: and splitting the data which is acquired from the server and transmitted to the user equipment into a third path of data and a fourth path of data according to a preset splitting strategy.
In the embodiment of the present invention, the network node device may split, according to a preset splitting policy, data transmitted to the user equipment and acquired from the server into the third path of data and the fourth path of data. The third path of data and the fourth path of data are obtained by splitting the data acquired from the server according to a preset load sharing strategy. It should be noted that the third path of data is data encapsulated by a tunneling protocol GTP-U on the user plane, and the fourth path of data is data encapsulated by a network protocol IP.
In an embodiment, when the network node device receives data transmitted to the user device by the server, the network node device may split and encapsulate the data into a third path of data encapsulated by a tunneling protocol GTP-U on a user plane and a fourth path of data encapsulated by a network protocol IP according to a preset splitting policy.

For example, if the network node device acquires data transmitted by a server to two user devices, the network node device may send, through a third generation partnership project 3GPP network, the split third path of data to the terminating cell, and send, through a non-3GPP network, the split fourth path of data to the terminating cell, so that the terminating cell aggregates the third path of data and the fourth path of data according to a determined aggregation policy, and sends the aggregated data to the two user devices.
In the embodiment of the invention, the network node equipment divides the data transmitted to the user equipment acquired from the server into the third path of data and the fourth path of data according to a preset dividing strategy by acquiring the data transmitted by the server, and transmits the third path of data and the fourth path of data acquired after division to the terminating cell, so that the data can be divided by the network node equipment arranged in the network and the divided data can be transmitted through the 3GPP network and the non-3GPP network, and the throughput of the terminating cell is improved.
