The communication system method and the device provided by the embodiment of the invention are applied to an application scene that UE needs to be connected to a network, in particular to the application scene that the UE needs to be accessed to the network to further acquire service data from the network. When the location information of the SRU device (the location information of the UE is the same as the location information of the SRU device) changes, the communication distance between the original DU device (i.e., the DU device connected to the SRU at the initial location, for example, the first DU device) and the SRU may be longer, so that the SRU device needs to determine the DU device (for example, the second DU device) with a shorter communication distance and establish a communication relationship with the second DU device, and then the SRU device may obtain the service data through the second DU device and send the service data to the UE.
As shown in fig. 3, the communication method provided by the embodiment of the present invention may include S101-S104.
S101, the SRU equipment acquires the current position information of the SRU equipment from the network management equipment.
It should be understood that the network management device may obtain the current location information of the SRU device, which is the same as the current location information of the UE, that is, the location information of the UE and the location information of the SRU device are changed at the same time.
For example, in a high-speed train scenario, the SRU device may be deployed in a certain car of a high-speed train, and the UE may be understood as a user handheld device on the train.
S102, the SRU determines the identification information of at least one second DU device according to the current position information of the SRU device.
It should be understood that the SRU device may store therein a correspondence between location information of the SRU and identification information of the DU device. For the SRU device, one location information thereof may correspond to one DU device identification information, or may correspond to a plurality of DU device identification information; for a DU device, it corresponds to only one identification information.
Illustratively, table 1 and table 2 below are an example of location information of an SRU device and identification information of a DU device, and an example of identification information of a DU device and a DU device, respectively.
TABLE 1
Location information for SRU devices Identification information of DU device
Location information 1 Identification information 1
Location information 2 Identification information 1 and identification information 2
Position information 3 Identification information 2 and identification information 3
Location information 4 Identification information 3 and identification information 4
Position information 5 Identification information 4
TABLE 2
Identification information of DU device DU device
Identification information 1 DU arrangement 1
Identification information 2 DU arrangement 2
Identification information 3 DU arrangement 3
Identification information 4 DU arrangement 4
From tables 1 and 2, assuming that the current location information of the SRU device is location information 3, the SRU device determines the identification information of the at least one second DU device to be identification information 2 and identification information 3, and the SRU device determines the at least one second DU device to be DU device 2 and DU device 3.
S103, the SRU equipment determines whether the identification information which is different from the identification information of the at least one first DU exists in the identification information of the at least one second DU.
And at least one first DU device is a DU device for establishing communication connection at the initial position by the SRU device.
It should be understood that, the at least one first DU device indicates, for a DU device that establishes a communication connection at an initial location for the SRU device, that the identification information of the at least one first DU device is the location information corresponding to the initial location, and the identification information of the corresponding DU device.
It is to be appreciated that the SRU device may determine whether the location of the SRU device has changed by determining whether there is identification information in the identification information of the at least one second DU device that is different from the identification information of the at least one first DU device. In the presence of identification information that is different from the identification information of the at least one first DU device in the identification information of the at least one second DU device, it is described that the location of the SRU device changes, specifically, the current location of the SRU device is different from the initial location of the SRU device, and the SRU device may need to connect a new DU device; in the case that there is no identification information different from the identification information of the at least one first DU device in the identification information of the at least one second DU device (i.e., in the case that the identification information of the at least one second DU device is the same as the identification information of the at least one first DU device), it indicates that the location of the SRU device has not changed, and the SRU device may continue to communicate with the at least one first DU device.
For example, in combination with table 1 and table 2, assuming that the location information corresponding to the initial location of the SRU device is location information 2, the SRU device determines that the identification information of the at least one first DU device is identification information 1 and identification information 2, and the SRU device determines that the at least one first DU device is DU device 1 and DU device 2.
S104, in the case that the identification information of the at least one second DU device is different from the identification information of the at least one first DU device, the SRU device sends a connection request message to the target second DU device.
The target second DU device is a DU device corresponding to identification information different from the identification information of the at least one first DU device in the at least one second DU device, and the connection request message is used to request the target second DU device to establish a communication connection with the SRU device.
It should be understood that the identification information of the target second DU device is different from the identification information of the at least one first DU device, indicating that the target second DU device is closer in communication distance to the SRU device with which the target second DU device is more suitable for communication.
Exemplarily, with reference to the examples in S102 and S103, the identification information of the at least one second DU device is identification information 2 and identification information 3, and the identification information of the at least one first DU device is identification information 1 and identification information 2, that is, the SRU device determines that, in the identification information of the at least one second DU device, there is identification information that is different from the identification information of the at least one first DU device (specifically, identification information 3 is identification information that is different from the identification information of the at least one first DU device), since the DU device corresponding to identification information 3 is DU device 3, the SRU device determines that the DU device 3 is the target second DU device, and the SRU device sends the connection request message to the DU device 3.
In an implementation manner of the embodiment of the present invention, in the case that there is no identification information that is different from the identification information of the at least one first DU device in the identification information of the at least one second DU device, the SRU device continues to communicate with the at least one first DU device.
In the communication method provided by the embodiment of the invention, the SRU equipment acquires the current position information of the SRU equipment from the network management equipment; then, the SRU device determines the identification information of at least one second DU device according to the current position information of the SRU, and determines whether the identification information of the at least one second DU device is different from the identification information of the at least one DU device, and the at least one DU device establishes communication connection for the SRU device at the initial position; then, in the presence of identification information that is different from the identification information of the at least one first DU device in the identification information of the at least one second DU device, the SRU device sends a connection request message to the target second DU device, where the target second DU device is a DU device corresponding to identification information that is different from the identification information of the at least one first DU device in the at least one second DU device, and the connection request message is used to request the target second DU device to establish a communication connection with the SRU device. In the embodiment of the invention, under the condition that the SRU equipment determines that the position of the SRU equipment changes, the communication connection can be established with the DU equipment with a shorter communication distance (namely the target second DU equipment), so that the UE can acquire the service data through the DU equipment with the shorter communication distance, the efficiency of the UE in acquiring the service data can be improved, and the communication quality is improved.
In one implementation manner, the communication method provided by the embodiment of the present invention further includes step a.
Step A, under the condition that identification information different from the identification information of the at least one first DU device exists in the identification information of the at least one second DU device, the SRU device disconnects the communication relation with the target first DU device.
The target first DU device is a DU device corresponding to identification information different from identification information of at least one second DU device in at least one first DU device.
It should be understood that the identification information of the target first DU device is different from the identification information of the at least one second DU device, indicating that the target first DU device is already unsuitable for communication with an SRU device at a relatively large communication distance from the SRU device.
Exemplarily, with reference to the example in S104, the SRU device determines that the identification information 1 is identification information different from the identification information of the at least one second DU device, and because the DU device corresponding to the identification information 1 is the DU device 1, the SRU device determines that the DU device 1 is the target first DU device, and the SRU device disconnects the communication relationship with the DU device 1.
It should be noted that the execution sequence of the above step a and step S104 is not limited in the embodiment of the present invention. For example, step a may be performed after step S104 is performed, or step a may be performed before step S104 is performed, or both step a and step S104 may be performed.
In another implementation manner, the communication method provided by the embodiment of the present invention further includes steps B to C.
And step B, under the condition that the identification information which is different from the identification information of the at least one first DU equipment exists in the identification information of the at least one second DU equipment, the SRU equipment determines whether the identification information which is the same as the identification information of the at least one first DU equipment exists in the identification information of the at least one second DU equipment.
In conjunction with the above description of the embodiments, it should be understood that the SRU device is able to determine whether the location of the SRU device has changed by determining whether there is identification information different from the identification information of the at least one first DU device in the identification information of the at least one second DU device. On the basis that the SRU device determines that its location has changed, the SRU device may also determine that the location of the SRU device has changed by determining whether the same identification information as that of the at least one first DU device exists in the identification information of the at least one second DU device.
And step C, if the identification information of the at least one second DU equipment is the same as the identification information of the at least one first DU equipment, the SRU equipment determines that the current position of the SRU equipment is the adjacent position of the initial position.
It should be understood that, if the SRU device determines that the identification information of the at least one second DU device is the same as the identification information of the at least one first DU device, it indicates that the at least one second DU device is the same as the at least one first DU device (hereinafter referred to as a target DU device), that is, the SRU device may communicate with the target DU device at the initial location and may also communicate with the target DU device at the current location. In the embodiment of the invention, the SRU equipment determines the adjacent positions of two positions corresponding to the same DU equipment (namely, the two positions are communicated with the same DU equipment).
Illustratively, in conjunction with the example in S104, the SRU device determines that the DU device 2 is the target DU device, and at this time, the SRU device determines that the current location of the SRU device is an adjacent location to the initial location of the SRU device.
Optionally, in combination with the high-speed train scenario example in S101, a power carrier device may also be deployed on the high-speed train. Specifically, the power carrier device is used for demodulating a power signal, and the SRU device is further configured to convert a baseband digital signal sent by the DU device to the SRU device into an analog signal, so that the UE can use the analog signal. In addition, the DU device can be deployed in a high-speed rail traction substation, that is, signals between the DU device and the SRU device are transmitted on a power line, and at this time, the DU device also has a relay function.
It should be understood that, in the above embodiment, the CU device and the plurality of DU devices may transmit data through the F1 interface through optical fiber, that is, the CU device performs data transmission with the plurality of DU devices through the F1 interface in a communication manner using optical fiber. The SRU device may transmit NGCPRI data with the at least one DU device through a power line carrier, that is, the SRU device performs data transmission with the at least one DU device through an NGCPRI interface in a power line carrier communication manner.
