Step 801: the wireless transceiver unit 102 receives the message sent by the UE101.

Step 802: The wireless transceiver unit 102 estimates and obtains the speed information of the UE 101 according to the received message.

Step 803: The wireless transceiver unit 102 adds the speed information to the message sent by the UE101.

Step 804: The wireless transceiver unit 102 reports the message carrying the speed information to the resource management unit 103.

The transmission method of the speed information in the uplink direction is described in detail below by taking the connection establishment request message, the cell update request message and the service data message as examples respectively.

Referring to FIG. 9, the specific implementation process of the speed information transmission method when UE101 sends a connection establishment request message is as follows:

Step 901: The wireless transceiver unit 102 receives the connection establishment request message sent by the UE 101 through the RACH.

Step 902: The wireless transceiver unit 102 estimates the velocity value of the UE 101 according to the connection establishment request message, and determines the accuracy value of the moving velocity.

Step 905: The wireless transceiver unit 102 sends a connection establishment request message carrying a speed code and a precision code to the resource management unit 103 through the RACH.

Step 908: The resource management unit 103 converts the speed code into an actual speed value, and converts the precision code into a precision value according to the corresponding relationships shown in FIGS. 3 , 6 and 7 .

Step 909: The resource management unit 103 compares the actual speed value with threshold 1 (low speed threshold in this embodiment) and threshold 2 (high speed threshold in this embodiment) to determine the cell type. An example of a specific implementation process is: first compare the actual speed value with the threshold value 1, if it is lower than the threshold value 1, it is determined that a pico cell needs to be accessed, otherwise the actual speed value is compared with the threshold value 2, if it is lower than the threshold value 1 If it is lower than the threshold value 2, it is determined that access to a micro cell is required, and if it is not lower than the threshold value 2, it is determined that access to a macro cell is required. The Accuracy value can be used as a reference for comparisons with Threshold 1 and Threshold 2. For example, if the actual value is 30km/h and the accuracy value is 60km/h, then the speed range is -30Km/h-90km/h, if the threshold value 1 is 80km/h, and the threshold value 2 is 120km/h, then The maximum speed of 90km/h exceeds the threshold value 1, indicating that the measurement result is inaccurate, and the UE in this situation can be fixedly connected to a certain type of cell (such as a pico cell).

Step 910: The resource management unit 103 determines the cell that the UE 101 needs to access according to the determined cell type.

Step 911: The resource management unit 103 sends a connection establishment response message to the UE101 through the wireless transceiver unit 102, which includes resource information allocated for the UE101 (including the access cell ID, etc.).

In step 908 and step 909, the resource management unit 103 can also obtain the speed value, take the absolute value of the speed value and compare it with the threshold value, or set a threshold value with a sign (including positive and negative signs), and compare the speed value Compared with the signed threshold value, -30 in Figure 3 is a threshold value.

Referring to Figure 11, the specific implementation process of the speed information transmission method when UE101 sends a cell update request message is as follows:

Step 1101: The wireless transceiver unit 102 receives the cell update request message sent by the UE 101 through the RACH.

Step 1102: The wireless transceiver unit 102 estimates the velocity value of the UE 101 according to the cell update request message, and determines the accuracy value of the moving velocity.

Step 1103: The wireless transceiver unit 102 converts the obtained speed value into a corresponding speed code, and converts the precision value into a precision code.

Step 1104: The wireless transceiver unit 102 adds the obtained speed code and precision code to the cell update request message.

Step 1106: The resource management unit 103 receives the cell update request message carrying the speed code and precision code.

Step 1107: The resource management unit 103 extracts the speed code and precision code from the cell update request message.

Step 1108: The resource management unit 103 converts the speed code into an actual speed value, and converts the precision code into a precision value according to the corresponding relationships shown in FIGS. 3 , 6 and 7 .

Step 1109: The resource management unit 103 compares the actual speed value with threshold 1 and threshold 2 respectively to determine the cell type.

Step 1110 : the resource management unit 103 compares the determined cell type with the cell type of the cell to which the UE 101 currently belongs, and if the cell types are the same, proceed to step 1111 , otherwise proceed to step 1112 .

Step 1111 : the resource management unit 103 sends a cell update response message to the UE 101 through the wireless transceiver unit 102 .

Step 1112: The resource management unit 103 determines that the UE 101 needs cross-layer access, and initiates a handover process, so that the UE 101 is handed over to a cell corresponding to the determined cell type. For example, the UE 101 is handed over from the micro cell where it is located to the macro cell where it is located.

Referring to Figure 12, the specific implementation process of the speed information transmission method when UE101 sends a service data message is as follows:

Step 1201: The wireless transceiver unit 102 receives the service data message sent by the UE 101 through the DCH.

Step 1202: The wireless transceiver unit 102 estimates the velocity value of the UE 101 according to each service data message, and determines the accuracy value of the moving velocity.

Each time a cycle is reached, continue with the following steps. Wherein, the wireless transceiver unit 102 knows that a cycle has been reached through the triggering of the internal timer. The wireless transceiver unit 102 can report speed information in real time through each service data message, so that the resource management unit 103 can monitor the moving speed of the UE 101 in real time, and can adjust allocated resources in real time. The wireless transceiver unit 102 uses periodic reporting, which can save system resources.

Step 1203: The wireless transceiver unit 102 converts the obtained speed value into a corresponding speed code, and converts the precision value into a precision code.

The structure of the DCH data frame Can be defined by yourself.

Step 1205: The wireless transceiver unit 102 sends the service data message carrying the speed code and precision code to the resource management unit 103 through the DCH.

Step 1206: The resource management unit 103 receives the service data message carrying the speed code and precision code.

Step 1207: The resource management unit 103 extracts the speed code and precision code from the service data message.

Step 1208: The resource management unit 103 converts the speed code into an actual speed value, and converts the precision code into a precision value according to the corresponding relationships shown in FIGS. 3 , 6 and 7 .

Step 1209: The resource management unit 103 compares the actual speed value with the threshold value 1 and the threshold value 2 to determine the cell type.

Step 1210: The resource management unit 103 compares the determined cell type with the cell type of the cell that UE101 currently belongs to. If the cell type is the same, end this process, or continue to step 1206. If UE101 needs to switch cells, make UE101 Switch to the cell at the same layer; if the cell types are inconsistent, proceed to step 1211.

Step 1211: The resource management unit 103 determines that the UE 101 needs cross-layer access, and initiates a handover process, so that the UE 101 is handed over to a cell corresponding to the determined cell type.

The foregoing embodiments describe in detail the implementation process of uplink speed information transmission, and describe the process in which the resource management unit 103 allocates resources according to the speed information. The following is an introduction to the implementation method of downlink speed information transmission, as shown in Figure 13, the main method flow of downlink speed information transmission is as follows:

Step 1301: The resource management unit 103 determines that there is a message that needs to be sent to the UE101.

Step 1302: The resource management unit 103 determines that the speed information of the UE 101 is stored locally.

Step 1303: The resource management unit 103 adds the speed information to the message to be sent to the UE 101 .

Step 1304: The resource management unit 103 sends a message carrying speed information to the wireless transceiver unit 102.

The messages that need to be sent to UE101 include connection establishment response message, cell update response message, service data message and so on. The following takes the connection establishment response message as an example for a detailed description, as shown in Figure 14, and the specific method flow is as follows:

Step 1401: The resource management unit 103 determines that there is a message that needs to be sent to the UE 101 by receiving a message sent by an external device or a message generated internally. For example, the resource management unit 103 generates a connection establishment response message.

Step 1402: The resource management unit 103 searches locally for the speed information corresponding to the UE 101 according to the identifier of the UE 101. This embodiment uses the speed value as an example for illustration.

Step 1403: The resource management unit 103 adds the speed value to the connection establishment response message, wherein the structure of the FACH data frame used to carry the connection establishment response message is similar to that of the RACH data frame, as shown in FIG. 10 .

Step 1404: The resource management unit 103 sends a connection establishment response message carrying a speed value to the wireless transceiver unit 102 through the FACH.

The above steps realize the transmission of the speed information on the downlink, and an example of an application scenario of the speed information on the downlink will be described below.

Step 1405: The wireless transceiver unit 102 receives the connection establishment response message carrying the speed value.

Step 1406: The wireless transceiver unit 102 extracts the speed value from the received connection establishment response message.

Step 1407: The wireless transceiver unit 102 estimates some parameter values when sending a message to the UE 101 according to the obtained speed value.

Step 1408: The wireless transceiver unit 102 sends a connection establishment response message to the UE 101 according to the obtained parameter value.

The embodiment of the present invention is described in detail by taking the wireless transceiver unit to estimate the speed of the UE and report the speed information as an example. If the UE also has the function of speed estimation, the UE can carry the local speed information in the sent message and report it to the network. On the side, the wireless transceiver unit only needs to forward the message of the UE to the resource management unit. The data frame structure adopted by the UE when sending a message is the same as the data frame structure adopted by the wireless transceiver unit in the above embodiment, as shown in FIG. 10 .

Usually, the UE only needs to occupy a large amount of system resources when it is in the active state, so when the UE is in the active state, it pays more attention to the speed information of the UE, and allocates appropriate system resources for it. When the UE enters the active state, it sends messages through the RACH; when it remains active, it exchanges service data with the network side through the DCH. This embodiment provides a specific implementation method of transmitting speed information through data frames of RACH and DCH, which covers the whole process of UE being in the active state, and can obtain the speed information of UE in time and allocate appropriate system resources to it, which not only meets the requirements of UE needs and save system resources. When the UE is in a state other than the active state (such as idle state, detached state, etc.), it occupies less system resources and can be ignored, so the speed of the UE at this time may not be concerned. If the speed information of the UE also needs to be obtained when the UE is in a state other than the activated state, the method for transmitting the speed information may refer to the foregoing embodiments, which will not be repeated here.
