It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
As shown in fig. 1, a data transmission method according to an embodiment of the present invention is applied to a terminal, and includes:
According to step 101, the terminal applying the method of the embodiment of the present invention can send the first packet to a first network device of a first type of network (first network) that is a sending object of the first packet, because the first packet includes the first packet and routing information, and the routing information is used to instruct a second network device of a second type of network (second network) that the first packet is transmitted to a core network, the first network device forwards the first packet to the second network device, and the second network device forwards the packet to the core network of the second network, thereby implementing inter-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, that is, 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 present invention may be applied to a heterogeneous network cooperative communication scenario in which the first network is an EUHT network and the second network is a 5G network; the method can also be applied to a scene that the first network is a wireless local area network (WIFI) network and the second network is heterogeneous network cooperative communication of 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 comprises at least one of:
an identification ID of the terminal;
an ID of the first network device;
an ID of the second network device;
the bearer ID.
Here, the source of the first packet is known by the ID of the terminal; knowing a transmission node of the first data packet in the first network through the ID of the first network equipment; the transmission node of the first data packet in the second network can be known through the ID of the second network equipment; by the bearer ID, the data transport bearer is known. 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 negotiated agreement or is 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, specifically:
receiving indication information sent by the second network equipment;
and selecting the first network equipment according to the indication information and the signal strength of at least one network equipment in the first network.
Here, the terminal is instruction information transmitted from the second network device and used for instructing the terminal to communicate with the device of the first network when accessing the second network. Thus, 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 first network device can be selected by combining the received indication information and the signal strength of at least one network device in the first network.
Preferably, the first network device is a first network device with the largest signal strength or greater than a preset threshold value in at least one network device in the first network.
Of course, the selection of the first network device may be performed using the signal power or other indicators derived from the signal power, besides the signal strength, which is not listed here.
Wherein the indication information comprises at least one of:
an indication of the measurement;
a frequency point of the second network device;
the ID of the second network device.
Here, the measurement indication is for instructing 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 equipment are used for indicating the second network equipment expected by the terminal so as to measure in a targeted manner and improve the measurement efficiency.
In addition, in this embodiment, after the first data packet is delivered to the core network, the core network would perform corresponding downlink data transmission. Thus, optionally, the method further comprises:
receiving a second packet via the first network device, wherein the second packet comprises 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 in reverse direction to the upload of the first packet. That is, the core network of the second network sends the second data packet (downlink data) to the second network device, and the second network device sends the second information packet including the second data packet and the routing information to the first network device, and finally, the first network device transfers the second information packet to the terminal. Of course, the format of the second packet received by the terminal is already in the packet format of the first network at this time because the second packet passes through the first network device, that is, the second packet is carried by the packet format of the first network.
The routing information of the second information packet is realized in the same way as the routing information of the first information packet, and comprises at least one of the following items: the ID of the terminal; an ID of the first network device; an ID of the second network device; the bearer ID. The details are not described herein.
Optionally, in this embodiment, before selecting the first network device of the first network, the method further includes:
in the case of returning from a connected state to an inactivated state, storing security configuration information used in the connected state; and when the terminal is in the connection state, the terminal accesses the second network.
Optionally, the first data packet and the second data packet are both encrypted and/or integrity-protected by using 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 was established with the second network, considering that the data security of the operator managing network is manageable. The security configuration information includes a key, encryption algorithm information, and the like. In the data transmission process, the terminal can adopt the security configuration information to encrypt and/or protect the integrity of the first data packet and then transmit the first data packet to the network side; and the second network equipment 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 equipment.
Of course, in the embodiment, if the terminal wants to obtain final data for the second packet subjected to the encryption and/or integrity protection processing, optionally, after receiving the second packet via the first network device, the method further includes:
and decrypting and/or verifying integrity protection on the second data packet according to the security configuration information, and obtaining a decoded data packet.
For example, the terminal decrypts the second data packet encrypted using the key based on the key in the security configuration information. Of course, the form of the key may be a symmetric key, an asymmetric key, etc.
The application of the method of the embodiment of the present invention is described below with reference to specific scenarios:
1. after the terminal registers and accesses to 5G or LTE (second network), the terminal resides in a cell of the 5G or LTE. The implementation of registration and access is not described 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 bearer.
3. And the base station of the cell sends indication information of the EUHT or WIFI system (first network) to the terminal. The terminal detects the signal power of the network equipment in the first network and selects the first network equipment from the signal power.
4. When the terminal has uplink data to send, the terminal sends an information packet to a first network device (a communication unit of a first network), and the information packet carries at least one of the following information:
a data packet encrypted using an encryption algorithm (security configuration information) configured by a second network device (communication unit of the second network);
terminal ID (routing information);
second network device ID (routing information);
bearer ID (routing information).
And the first network equipment receives the information packet and sends a data packet and/or routing information or a part of the routing information to the second network equipment 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 from the first network to the Internet, but must be sent via the second network deployed by the operator, and the unification of the charging function can be achieved, that is, the operator of the second network uniformly charges the data regardless of whether the terminal directly sends the data through the second network (5G) or the first network (WIFI or EUHT). 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, that is, after receiving the information packet, the data is forwarded to the corresponding network device according to the routing table.
As shown in fig. 2, the first network (EUHT or WIFI network) has only a physical layer (PHY layer) and a network layer (MAC layer), and the second network (5G or LTE network) has 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). When the different networks are used for cooperative communication, 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 from the PDCP layer or the RLC layer of the second network and transmitted downwards 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 can also be transmitted only in the second network, from the PDCP layer down to the PHY layer.
