As shown in fig. 1, a data transmission method in an embodiment of the present invention is applied to a terminal, and includes:
Step 101, a first information packet is sent to a first network device of a first network; wherein the first network is a first type of network; the first information packet includes a first data packet and routing information, where the routing information is used to indicate a second network device through which the first data packet is transmitted to a core network, the second network device belongs to a second network, and the second network is a second type network.
According to step 101, the terminal applying the method of the embodiment of the present invention can send the first packet to a sending object of the first packet, that is, a first network device of a first type network (first network), and the first packet includes a first data packet and routing information, where the routing information is used to indicate a second network device of a second type network (second network) through which the first data packet is transmitted to the core network, so that the first network device forwards the first data packet to the second network device, and the second network device submits the data packet to the core network of the second network, thereby implementing heterogeneous network cooperative communication.
Wherein the first network device and the second network device are communication units of a network, which may be base stations, hotspots, cells, etc.
Optionally, the first network is a first type of network, i.e. a wireless local area network; the second network is a second type of network, i.e. a cellular mobile network. For example, the method of the embodiment of the invention can be applied to a heterogeneous network cooperative communication scene in which a first network is EUHT networks and a second network is 5G networks; the method can also be applied to a heterogeneous network cooperative communication scene in which the first network is a wireless local area network (WIFI) network and the second network is an LTE network.
Of course, the first type of network may also be a cellular mobile network, and correspondingly, the second type of network may also be a wireless local area network.
In this embodiment, the routing information is information for identifying a destination node, a source node, a path, or a bearer, so as to implement transmission of information between the network device and the terminal. Optionally, the routing information includes at least one of:
An identification ID of the terminal;
an ID of the first network device;
An ID of the second network device;
carrying the ID.
Here, the source of the first packet is known by the ID of the terminal; knowing the transmission node of the first data packet in the first network through the ID of the first network device; knowing the transmission node of the first data packet in the second network through the ID of the second network device; the data transmission bearer is known by the bearer ID. Of course, at least one of the identification ID of the terminal, the ID of the first network device and the ID of the second network device has been agreed, or otherwise known, and the routing information may not include the information.
Additionally, optionally, the method further comprises: selecting a first network device of a first network, in particular:
Receiving indication information sent by the second network equipment;
and selecting the first network equipment according to the indication information and the signal intensity of at least one network equipment under the first network.
Here, the terminal is indication information transmitted by the second network device and received in the case of accessing the second network, where the indication information is used to instruct the terminal to communicate with the device of the first network. When the second network releases the terminal and the terminal returns to the inactive state and needs to transmit data to the core network of the second network via the first network, the received indication information and the signal strength of at least one network device in the first network can be combined to select the first network device.
Preferably, the first network device is a first network device with the maximum signal strength or greater than a preset threshold value in at least one network device under the first network.
Of course, the selection of the first network device may be accomplished using signal power or other indicators derived from signal power in addition to signal strength, which is not explicitly recited herein.
Wherein the indication information includes at least one of:
A measurement indication;
A frequency point of the second network device;

Here, the measurement indication is used to instruct the terminal to initiate a signal strength measurement to select the first network device based on the signal strength; the frequency point and the ID of the second network device are used for indicating the second network device expected by the terminal so as to measure in a targeted manner, and the measurement efficiency is improved.
In addition, in this embodiment, after the first data packet is submitted to the core network, the core network will often perform corresponding downlink data transmission. Thus, optionally, the method further comprises:
A second packet is received via the first network device, wherein the second packet includes a second data packet and the routing information, and the second packet is forwarded via the second network device.
Here, the terminal receives the downlink data of the core network of the second network and the uploading of the first data packet is performed in reverse. That is, the core network of the second network transmits a second data packet (downlink data) to the second network device, and the second network device transmits a second packet including the second data packet and routing information to the first network device, and finally the first network device delivers the second packet to the terminal. Of course, the second packet received by the terminal, because of the first network device, has been in the packet format of the first network at this time, i.e. the second packet is carried by the packet format of the first network.
The implementation of the routing information of the second information packet is the same as that of the first information packet, and the routing information of the second information packet comprises at least one of the following: an ID of the terminal; an ID of the first network device; an ID of the second network device; carrying the ID. The details are not described here.
Optionally, in this embodiment, before the selecting the first network device of the first network, the method further includes:
storing security configuration information used by the connection state under the condition of returning to the non-activated state from the connection state; and when the terminal is in the connection state, the terminal is accessed to the second network.
Optionally, the first data packet and the second data packet are encrypted and/or integrity protected by adopting the security configuration information.
Here, the second network is preferably a cellular mobile network, and the terminal stores security configuration information used when a connection is established or has been established with the second network in consideration of the fact that data security of the operator-controlled network is controllable. Wherein the security configuration information includes a key, encryption algorithm information, and the like. In the data transmission process, the terminal can encrypt and/or protect the integrity of the first data packet by adopting the security configuration information and then transmit the first data packet to the network side; and the second network device adopts the security configuration information to encrypt and/or protect the integrity of the second data packet, and then transmits the second data packet to the terminal through the first network device.
Of course, for the second data packet subjected to encryption and/or integrity protection processing, if the terminal is to obtain the final data, in this embodiment, optionally, after receiving the second data packet via the first network device, the method further includes:
And decrypting and/or checking the integrity protection of the second data packet according to the security configuration information, and obtaining the decoded data packet.
For example, the terminal uses the decryption of the second data packet encrypted by the key based on the key in the security configuration information. Of course, the key may be in the form of a symmetric key, an asymmetric key, etc.
The application of the method according to the embodiment of the present invention is described below with reference to specific scenarios:
1. after the terminal registers and accesses 5G or LTE (second network), the terminal resides in the cell of the 5G or LTE. The implementation of registration and access is not described in detail herein.
2. The base station (second network device) of the cell configures an encryption algorithm for the terminal and starts encryption to establish user plane bearing.
3. The base station of the cell sends EUHT or indication information of the WIFI system (first network) to the terminal. The terminal detects the signal power of the network device under the first network and selects the first network device from the signal power.
4. When the terminal has uplink data to send, the terminal sends an information packet to the first network device (communication unit of the first network), wherein the information packet carries at least one of the following information:
A data packet encrypted using an encryption algorithm (security configuration information) configured by the second network device (communication unit of the second network);
Terminal ID (routing information);
a second network device ID (routing information);
Bearer ID (routing information).
The first network device receives the information packet, and sends the data packet and/or the routing information or a part of the routing information to the second network device according to the routing information carried in the information packet. The second network device delivers the data packet to a PDCP (PACKET DATA Convergence Protocol ) layer of the bearer of the terminal in the second network, and further delivers the data packet to the core network. Here, the data is not directly sent to the Internet by the first network, but must be sent via a second network deployed by the operator, and the charging function can be unified, that is, the data sent by the terminal directly through the second network (5G) or the first network (WIFI or EUHT) is uniformly charged by the operator of the second network. Unlike the existing dual connectivity architecture, the network side does not need to establish a connection between the first network and the second network for each UE. Only the routing connection is maintained between the first network and the second network, namely, after the information packet is received, the data is forwarded to the corresponding network equipment according to the routing table.
As shown in fig. 2, the network protocol stack of the network side includes a first network (EUHT or WIFI network) having only a physical layer (PHY layer) and a network layer (MAC layer), and a second network (5G or LTE network) having a PHY layer, a MAC layer, a radio link control layer (RLC layer), a PDCP layer, a radio resource control layer (RRC layer), and a service data adaptation layer (SDAP). During the cooperative communication of the different networks, the data of the second network is transmitted to the first network, and the data can be transmitted to the MAC layer of the first network by the PDCP layer or the RLC layer of the second network and downwards transmitted to the PHY layer; and the data of the first network is transmitted to the second network, and the data is reversely transmitted based on the transmission path. Of course, the data of the second network may also be transmitted only within the second network, down to the PHY layer by the PDCP layer.
