Description

Data transmitting method, data transmitting terminal, and base station Technical field

The present invention relates to the field of communications, and in particular, to a data transmitting method, a data transmitting terminal, and a base station.

Background technique

With the development of wireless multimedia services, people's demand for high data rates and user experience is increasing, which puts high demands on the system capacity and coverage of traditional cellular networks. On the other hand, the popularity of applications such as social networking, near-field data sharing, and local advertising has led to an increasing demand for people who understand and communicate with nearby people (Proximity Services). Traditional cell-based cellular networks have significant limitations in supporting high data rates and proximity services. In this context, D2D (Device-to-Device), which represents a new direction for future communication technologies, is emerging. Technology came into being. The application of D2D technology can reduce the burden of cellular networks, reduce the battery power consumption of user equipment, increase the data rate, and improve the robustness of the network infrastructure, which satisfies the requirements of the above high data rate services and proximity services.

D2D technology can work in licensed or unlicensed bands, allowing multiple D2D-enabled user equipment (D2D User Equipment, D2D UEs to perform direct discovery with or without network infrastructure). Direct communication. D2D technology usually includes D2D discovery technology and D2D communication technology. D2D discovery technology refers to determining/determining the proximity between two or more D2D user devices (for example, within the scope of direct D2D communication) or A technique for determining/determining that a first user equipment is adjacent to a second user equipment. The D2D communication technology refers to a technology in which some or all of communication data between D2D user equipments can communicate directly without going through a network infrastructure.

FIG. 1 is a schematic diagram of data interaction according to the related art. As shown in FIG. 1 , there are mainly three D2D application scenarios of R12 and R13:

1) UE1 and UE2 perform data interaction under the coverage of the cellular network, and the user plane data does not pass through the network infrastructure, as shown in mode 1 of FIG. 1;

2) UE relay transmission in the weak/uncovered area, as shown in mode 2 of FIG. 1, allows UE4 with poor signal quality to communicate with the network through UE3 with network coverage nearby, which can help operators expand coverage and increase capacity. ;

3) In the event of an earthquake or emergency, the cellular network is not working properly, allowing direct communication between devices, as in Mode 3 of Figure 1, the control plane and user plane between UE5, UE6 and UE7 do not pass through the network infrastructure. Perform one-hop or multi-hop data communication.

In the above R13D2D scenarios 2) and 3), the D2D UE can serve as a relay node, so that the remote D2D UE covering the edge of the cellular network or the outside of the coverage can perform cellular communication with the network through the relay node UE, and the D2D UE passes through the medium. The node UE performs D2D communication. In R13 D2D, a D2D UE (also called a relay UE) as a relay node forwards data according to information such as a target IP address/port number in layer 3 (ie, IP layer), and in R14 D2D technology, consider wearable. The device (for example, the MTE or the NB-IoT device) accesses the network scenario through the relay UE, so that the operator (ie, the core network element MME, etc., and the base station) can more effectively manage the wearable device (ie, the remote UE). The relay UE is required to perform data routing and forwarding at layer 2, and the non-3GPP access technology (for example, WIFI or Bluetooth) is used between the remote UE and the relay UE. However, the prior art does not provide the remote UE through the non-3GPP. The access technology is connected to the relay UE and adopts the bearer configuration and mapping method in the layer 2 data routing and forwarding mode, so that the layer 2 relay function cannot be correctly executed.

Therefore, for the problem that the remote UE or the relay UE cannot normally transmit data when the remote UE is connected to the relay UE through the non-3GPP access technology in the related art, no solution has been proposed.

Embodiment 1

This embodiment describes a method for how a remote UE sends a data packet to a relay UE. The remote UE and the relay UE can communicate with a non-3GPP access technology, such as WIFI or Bluetooth. The WIFI technology can be used between the remote UE and the relay UE as an example. In the method of this embodiment, the process of sending the data packet to the relay UE by the remote UE is as follows:

The upper layer of the remote UE generates a data packet, and the data packet needs to be sent to the network side or other UE through the relay of the relay UE. Therefore, the remote UE needs to first send the data packet to the relay UE. Specifically, the remote UE sends the data packet generated by the upper layer to the relay UE through WLAN communication. In order to ensure the QoS of the data transmission, when the WLAN MAC layer data is encapsulated, the data packet of the remote UE is corresponding to the corresponding QoS parameter for the WLAN and sent to the relay UE.

The remote UE may obtain a mapping table between the Qu parameter of the Uu interface and the QoS parameter (for example, the user priority, UP) of the WLAN, and the remote UE may obtain the mapping table by using a pre-configured manner, or may be obtained from the core network element ( For example, ProSe Function) obtains the mapping table, or the mapping table can be obtained from the base station through system messages or RRC dedicated signaling.

The remote UE determines the user priority value corresponding to the data packet according to the QCI value of the bearer to which the data packet belongs, and the mapping table between the previously obtained Uu interface QCI parameter and the QoS parameter for the WLAN (for example, user priority, UP), and The user priority value is encapsulated in the MAC header when the WLAN MAC layer data encapsulation is performed. The remote UE then sends the data packet to the relay UE over the WLAN.

Embodiment 2

This embodiment describes a method 2 of how a remote UE sends a data packet to a relay UE, and a non-3GPP access technology communication, such as WIFI, between the remote UE and the relay UE. Bluetooth. The WIFI technology can be used between the remote UE and the relay UE as an example. In the method of this embodiment, the process of sending the data packet to the relay UE by the remote UE is as follows:

The upper layer of the remote UE generates a data packet, and the data packet needs to be sent to the network side or other UE through the relay of the relay UE. Therefore, the remote UE needs to first send the data packet to the relay UE. Specifically, the remote UE sends the data packet generated by the upper layer to the relay UE through WLAN communication. In order to ensure the QoS of the data transmission, when the WLAN MAC layer data is encapsulated, the data packet of the remote UE is corresponding to the corresponding QoS parameter for the WLAN and sent to the relay UE.

When the base station configures the EPS bearer/Uu bearer for the remote UE, the remote UE configures the bearer corresponding/associated QoS parameters for the WLAN (for example, user priority, UP). The base station may send the EPS bearer/Uu bearer of the remote UE and the corresponding QoS parameter for the WLAN to the remote UE through an RRC reconfiguration message.

The remote UE determines the user priority value corresponding to the QoS parameter (for example, user priority, UP) corresponding to the bearer of the data packet and the bearer configured by the base station, and the user priority is used when the WLAN MAC layer data is encapsulated. The priority value is encapsulated in the MAC header. The remote UE then sends the data packet to the relay UE over the WLAN.

Embodiment 3

This embodiment describes a method 1 in which a relay UE relays a data packet of a remote UE to a base station, and a non-3GPP access technology communication between the remote UE and the relay UE, such as WIFI and Bluetooth. The WIFI technology can be used between the remote UE and the relay UE as an example. In the method of this embodiment, the process in which the relay UE sends the data packet to the base station is as follows:

The relay UE receives the data packet sent by the remote UE, and identifies that the data packet needs to be forwarded to the base station, and forwards the data packet of the remote UE to the base station by using the Uu bearer of the relay UE.
