With the popularization and development of the internet, when a user needs to use a User Equipment (UE) and the UE is not located at the user's side, many people use remote desktop control software to connect the UE.
At present, a remote desktop application program with application software is used for remote desktop control, but the remote desktop application program with application software has the defects of high resource occupation and poor image quality effect. For example, the QQ remote desktop control has the advantages of large User group and early application period, but the QQ remote desktop control is encoded and sent by means of screen capturing and recording by depending on all User Interface (UI) information of the controlled User equipment, and then transmitted to the control equipment in real time through a network, received by the control equipment, decoded and restored, namely, consistent with the UI information of the currently controlled equipment, so that the transmission process causes large system resource occupation and frequent occurrence of frame rate or jamming.
The other is microsoft (Windows) remote desktop connection, which is a native remote desktop connection, belonging to the C/S (client/server) mode, using the remote desktop protocol (Remote Desktop Protocol, RDP) protocol.
At present, the remote connection computer schemes are mostly connected through WIFI or optical fibers, the activation time delay is longer, the standby power consumption is high, and each scheme has respective defects, such as high resources occupation, low image quality, complex Windows remote desktop connection configuration, and no defects of connection using multiple network modes, which also causes the problem of poor user experience.
In view of this, the embodiment of the invention provides a remote connection method with simple operation, low occupied resource, low power consumption and short activation time delay, and the remote connection method provided by the embodiment of the invention is described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a remote connection method according to an embodiment of the present invention. As shown in fig. 1, the remote connection method may include the steps of:
first, steps S101 to S103 are performed by the control device, specifically including:
s101, the control device acquires an address of the request control device and a password of the request control device.
The address of the control device obtaining request control device may be a physical address (Media Access Control, MAC) address of the user device, and the data packet can be uniquely corresponding to the target device due to the uniqueness of the MAC address in the whole network.
The password of the request control device is that the device for requesting control authenticates according to the password.
S102, the control device generates a data frame according to the address of the request control device and the password of the request control device.
In some embodiments, after the control device obtains the address of the requesting control device and the password of the requesting control device, a data frame is generated according to the address of the requesting control device and the password of the requesting control device.
As a specific example, the control device generates a corresponding remote wakeup data frame according to a Magic Packet (Magic Packet) standard, where the remote wakeup data frame may include a MAC address and a password for requesting control of the computer.
And S103, broadcasting a data frame to the user equipment by the control equipment, activating the user equipment by the user equipment according to the data frame, and establishing remote connection based on the network enhancement application slice with the control equipment.
In some embodiments, the control device may send the magic packet using a connectionless transport protocol, such as the user datagram protocol (User Datagram Protocol, UDP), sending port 7 or 9.
The magic packet may be sent on the data link layer, and during the sending process, may be broadcast onto a given network using a broadcast address, without using an internet protocol (Internet Protocol, IP) address.
As a specific example, a magic packet may be formed using 255 (FF FF FF FF FF FF) of 6 bytes, followed by 48 MAC addresses for the requesting control devices, repeated 16 times, followed by 4-6 bytes of cryptographic information, e.g., 123456123456 MAC addresses, 7890 for the requesting control devices, the magic packet being in the format:
FFFFFFFFFFFF 123456123456 123456123456 123456123456
123456123456 123456123456 123456123456 123456123456
123456123456 123456123456 123456123456 123456123456
123456123456 123456123456 123456123456 123456123456
123456123456 7890
the data frame is then transmitted to the internet by IP broadcasting using the UDP protocol.
In some embodiments, when the network card of the request control device supports a message that can be monitored under the conditions of ultra-low power consumption, such as standby, sleep, and soft-off, especially when the 5G large-scale internet of things (massive Machine Type of Communication, mctc) application slice is used, standby can be performed with lower power consumption.
After the user equipment is powered on, the user equipment is connected to a network, starts a large-scale internet of things (mMTC) application slice, and starts Wake-on-LAN (WOL) and is in a standby state.
The Wake On LAN is started in the network card setting of the main board basic input output system (Basic Input Output System, BIOS) of the user equipment, so that the network card can keep electrified under the conditions of sleeping, dormancy and soft shutdown of the user equipment, receives the information of the magic packet and wakes up the user equipment.
After the network card of the user equipment receives the magic packet with the same MAC address and checks the password successfully, the user equipment wakes up the computer, and the S104 to S105 can be executed specifically.
S104, the user equipment is switched from a standby state to an active state according to the data frame.
In some embodiments, after the user equipment receives the data frame sent by the control device, the user equipment may determine whether the device requesting control and the user equipment are the same device according to the address of the request control device and the password of the request control device, because the data frame includes the address of the request control device and the password of the request control device.
When the device requesting control is the same device as the user device, the user device switches from the standby state to the active state. The standby state of the user equipment is not limited to standby, sleep, soft-off, etc., and it is understood that the user equipment may also receive a data frame sent by the control device in an activated state.
As a specific example, the user device may be a personal computer of the user, where the network card of the personal computer analyzes the received data frame, and analyzes that the data frame includes the MAC address of the network card and the corresponding password information, and then the network card sends a wake-up signal to the power supply or the motherboard, activates the personal computer from the standby mode, and executes S105.
S105, the user equipment sends switching request information of the network slice to the core network equipment, wherein the switching request information comprises slice information of the network enhanced application slice requested to be switched by the user equipment; the switching request information is used for the core network equipment to route the network application slice corresponding to the user equipment to the network enhancement application slice according to the slice information of the network enhancement application slice.
In some embodiments, the network application slice may be an emtc application slice and the network enhanced application slice may be an enhanced mobile broadband (Enhanced Mobile Broadband, eMBB).
After receiving the handover request information of the network slice sent by the receiving user equipment, the core network device performs steps S106 to S107.
And S106, the core network equipment routes the network application slice corresponding to the user equipment to the network enhancement application slice according to the switching request information, and generates switching feedback information.
Because the handover request information received by the core network device includes slice information of the network enhanced application slice requested to be handed over by the user device, the core network device obtains slice information of the network enhanced application slice requested to be handed over by the user device, and then routes the network application slice corresponding to the user device to the network enhanced application slice.
In order to provide services for users more accurately, before switching, the core network equipment determines slice information of the corresponding network enhancement application slice which is set by the corresponding user equipment according to the slice information of the network enhancement application slice which is requested to be switched.
As a specific example, determining slice information of a network enhanced application slice to which the corresponding user equipment has set may be to confirm that the user has contracted and obtain network enhanced application slice usage rights.
After the core network device routes the network application slice corresponding to the user device to the network enhanced application slice, S107 is executed.
And S107, the core network equipment sends switching feedback information to the user equipment.
The core network device can be used for disconnecting the remote connection based on the network application slice with the control device according to the switching feedback information, and establishing the remote connection based on the network enhancement application slice with the control device.
After receiving the handover feedback information sent by the core network device based on the network enhanced application slice, the user device executes S108.
S108, the user equipment disconnects the connection with the control equipment based on the network application slice according to the switching feedback information, and establishes remote connection with the control equipment based on the network enhanced application slice.
In some embodiments, the remote connection of the control device to the user device may be established by RDP according to a data layer established by the international organization for standardization (International Organization for Standardization, ISO), first, the control device is connected to a server of the user device, and then, according to RDP protocol, the respective layers at the time of data transfer are established.
Wherein each level of data transfer includes a network connection layer defining a complete RDP data logical packet to avoid data loss due to fragmentation of the network packet length.
Above the network connection layer is an ISO data layer, which represents the normal connection communication of RDP data.
And on the ISO data layer, the virtual channel layer is used for splitting the data marked with different virtual channels, so that the processing speed of the user equipment is increased, and the time for occupying a network interface is saved.
And the data encryption and decryption layer is arranged above the virtual channel layer and is used for encrypting and decrypting all the functional data.
Above the encryption and decryption layer, a functional data layer is used for processing all functional data such as picture information, local resource conversion, sound data, print data and the like.
After the connection of the data layer is established, the user equipment and the control equipment receive encryption and decryption keys and apply for and open a virtual channel for transmitting functional data according to the related information of the initial protocol.
After the virtual channel is opened, the function data sent and received in the network connection is encrypted and decrypted through an encryption and decryption layer, wherein the encryption and decryption layer can comprise verification of an encryption protocol, authentication of a platform software certificate and the like.
Finally, after each function establishes connection successfully, the transmission of each function data between the control equipment and the user equipment is realized in the function data layer.
By adopting the RDP protocol, the data loss caused by the division of the network packet with overlong length can be avoided, the processing speed can be increased, and the time for occupying the network interface can be saved.
In the embodiment of the invention, after receiving the data frame sent by the control device, the user device can quickly analyze, verify and wake up the user device, and then the user device sends the slice switching request information to the core network.
After the user equipment receives the switching feedback information sent by the core network based on the network enhanced application slice, the user equipment can rapidly disconnect the connection with the control equipment based on the network application slice, establish the remote connection with the control equipment based on the network enhanced application slice, especially interact with the core network equipment through the access network equipment, then select the corresponding slice by the network slice selection function (Network Slice Selection Function, NSSF), and the AMF directly switches the slice by rerouting, thereby avoiding time delay caused by disconnection and reconnection, and realizing rapid slice conversion.
As a specific example, to clearly describe the flow of the core network device routing the network application slice corresponding to the user device to the network enhanced application slice according to the handover request information and generating the handover feedback information, the application slice handover flow is described below in connection with the application slice handover flow shown in fig. 2, and the application slice handover flow may include steps S201-S207.
S201, the access network equipment receives a slice switching request sent by the network card. The core network device receives the switching request information through the access network device, and the access network device accesses the access and mobility management function (Access and Mobility Management Function, AMF) in the currently used mMTC slice.
S202, the access network equipment accesses the currently used mMTC AMF.
S203, emtc AMF interacts with the unit deployment manager (Unit Deployment Manager, UDM) to confirm that the user has signed up for eMBB slices.
S204, the mMTC AMF uploads the eMBB slice requirement to the NSSF and requests the NSSF to select a corresponding slice.
S205, NSSF determines eMBB slices and returns an Allowed NSSAI to mMTC AMF, AMF Set.
S206, the mMTC reroutes to the target AMF, namely eMBB AMF according to the Allowed NSSAI returned by NSSF and the AMF Set.
S207, the eMBB AMF sends a switching response to the network card of the user equipment through the access network equipment.
As a specific example, the user equipment can connect with the eMBB AMF through the access network device based on the received handover feedback sent back by the core network device.
The user equipment receives the switching feedback information sent back by the core network equipment, disconnects the network card from the mMTC application slice in the user equipment, connects the eMBB application slice, and then the control equipment can control the user equipment.
The remote connection method provided by the invention has the advantages of low power consumption of the user equipment, short activation time delay, simple network mode switching realization and wide application effect, and can achieve the effects of low delay and low energy consumption in the application scene of the actual control user equipment due to the establishment of the remote connection based on the network enhanced application slice between the user equipment and the control equipment, thereby having better user experience.
