TECHNICAL FIELD Embodiments of the present invention relate to communication technologies, and in particular, to a transmission delay processing method, and a device and device thereof. Background technique

In the Wideband Code Division Multiple Access (WCDMA) Frequency Division Duplex (FDD) mode, the one-way Transport Propagation Delay (TP) of the air interface is determined by the physics in the base station. The random access channel (Physical Random Access Channel, PRACH for short) is calculated.

The base station sends the transmission delay to the Radio Network Controller (RNC) in the form of a Frame Protocol (FP) packet. The meaning, bearer and value range of TP are defined in the 3rd Generation Partnership Project (3GPP) 25.435 and 25.433 protocols, which are used in the previous protocols of WCDMA Release 7 (Release 7). The Propagation Delay indicates that the protocol field is 8 bits, the value range is 0 to 255, the quantization precision is 3 chips, and the actual range is 0 to 765 chips. In the Release 7 version, the force is increased. . The Extended Propagation Delay field expands the range of TP values. The protocol field is 10 bits, ranging from 255 to 1023, with a step size of 3 chips and an actual range of 765 to 3096 chips. Among them, the distance corresponding to 1 chip is 78.125 meters. According to the transmission delay, the distance between the base station and the user equipment can be obtained. When the dedicated channel is established, the RNC can send the TP value reported by the PRACH to the base station for configuring the corresponding dedicated channel.

However, in actual wireless networks, the coverage of hotspots, remote suburbs, and microcells is completely different. For hotspots and microcells, the stations are densely distributed, and most of the user equipment in the cell is distributed within 2 km of the base station ( The TP is less than 30 chips, and the distribution is dense, and the quantization precision of the TP in the FP packet is too coarse, resulting in low transmission delay accuracy.

It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic flowchart diagram of Embodiment 1 of a method for processing a transmission delay according to the present invention. Embodiments of the present invention provide a transmission delay processing method, which may be performed by any apparatus that performs a transmission delay processing method, and the apparatus may be implemented by software and/or hardware. In this embodiment, the device can be integrated in the base station. As shown in FIG. 1, the method in this embodiment may include:

Step 101: Acquire a transmission delay value, where the quantization precision of the transmission delay value is less than 3 codes. Film.

In this embodiment, the quantization precision of the transmission delay value is less than 3 chips. Those skilled in the art can understand that the quantization precision of the transmission delay value in this embodiment can be selected from 0.5 chips, 1 chip, 1.5 chips, 2 chips, and the like according to actual needs. In the specific implementation process, the appropriate quantization precision may be selected according to the experience or the distribution of the user equipment. For example, when the user equipment is densely distributed, 0.5 chips are selected, and when the user equipment is generally densely distributed, 1 chip is selected. For the selection of the specific value of the quantization precision, the embodiment is not particularly limited herein.

Step 102: Convert the transmission delay value into a transmission delay report value according to the quantization precision of the transmission delay value.

After obtaining the transmission delay value, the base station converts the transmission delay value into a transmission delay report value according to the quantization precision. In the actual application process, the base station may convert the obtained transmission delay value into a transmission delay report value according to the quantization precision and the rounding manner in the orientation, for example, when the quantization precision is 1 chip, the base station obtains the transmission. When the delay value is 2.5 chips, the transmission delay value of 2.5 chips is converted into the transmission delay reported value of 2 chips according to the quantization precision. However, if the quantization precision of 3 chips in the prior art is utilized, the value of the transmission delay is 0. It can be seen from the above that the finer the quantization precision, the more accurate the obtained transmission delay is.

Step 103: Report the transmission delay to the radio network controller to report the value.

According to the existing protocol, after the base station obtains the one-way transmission delay value of the air interface, the base station converts the transmission delay value into a transmission delay report value, and reports the transmission delay report value to the RNC in the form of an FP packet. The base station obtains the transmission delay report value sent by the RNC, and configures the dedicated channel according to the transmission delay and the 艮 value. In this embodiment, the dedicated channel (Dedicated Physical Channel, abbreviated as DPCH) includes a dedicated physical control channel (DPCCH) and a dedicated physical data channel (DPDCH).

Accurate refinement makes the transmission delay report higher accuracy.

FIG. 2 is a schematic flowchart diagram of Embodiment 2 of a method for processing a transmission delay according to the present invention. The embodiment of the invention provides a transmission delay processing method, which can be performed by any device that performs a transmission delay processing method, and the device can be implemented by software and/or hardware. In this embodiment, the device The device can be integrated in the wireless network controller. In this embodiment, on the basis of Embodiment 1 of the method for processing the transmission delay, the RNC receives the transmission delay reported by the base station, and sends the transmission delay value to the base station, so that the specific process of the base station establishing the dedicated channel is performed. Detailed description. As shown in FIG. 2, the method in this embodiment may include:

Step 201: Receive a transmission delay report value reported by the base station, where the quantization precision of the transmission delay report value is less than 3 chips.

After the base station converts the transmission delay value into the transmission delay report value according to the quantization precision, the base station sends a transmission delay report value to the RNC, and the RNC stores the transmission delay report value. The quantization precision of the transmission delay is less than 3 chips.

In addition, the RNC can also obtain the measurement report of the user equipment. In the specific implementation process, after the user equipment measures the wireless network to obtain a measurement report, the measurement report is sent to the base station, and then the base station sends the measurement report to the RNC. The measurement report includes the transmit power of the base station, the signal-to-noise ratio of the channel, and the Received Signal Code Power (RSCP).

The RNC can determine the network coverage information according to the transmission delay report value and the measurement report. Specifically, the RNC can determine the distance between the base station and the user equipment according to the transmission delay report value, and draw the coverage map of the user equipment. For example, when the quantization precision is 1 chip and the transmission delay is 20 chips, the distance between the base station and the user equipment is 1562.5 meters. The RNC can determine the distance between each user equipment and the base station according to multiple transmission delays. , draw an overlay map. The RNC can know the wireless coverage of the cell based on the measurement report. At the same time, the RNC can also comprehensively consider the transmission delay and the measurement report, and calculate the signal quality distribution of the user equipment corresponding to the different transmission delays, and analyze the coverage of the network.

In turn, the RNC can optimize the wireless network based on the network coverage information. For example, when the user equipment in the hotspot area is densely distributed and the network coverage is poor, the RNC may indicate to add a macro base station or a micro base station in the hotspot area. When the user equipment in the remote suburbs is loosely distributed and the network coverage is good, the configuration of the base station in the corresponding area is reduced.

A person skilled in the art can understand that in this embodiment, the quantization precision is refined, and the distance between the base station and the user equipment can be accurately obtained according to the transmission delay report value, and the coverage map drawn is highly identifiable, and the existing network optimization is supported. The need to provide an accurate basis for network optimization.

Step 202: Send a radio link setup request message to the base station, and the radio link setup request is cancelled. The information includes an indication of the transmission delay report value and the quantization precision.

When the base station needs to establish a dedicated channel, the RNC sends an identifier of the transmission delay report value and the quantization precision to the base station by sending a radio link setup request message to the base station.

In the embodiment of the present invention, by receiving the transmission delay report value reported by the base station, the quantization precision of the transmission delay value is less than 3 chips, and the quantization precision is more accurately refined, and the accuracy of the transmission delay reporting value is higher.

The technical solutions of the first embodiment of the transmission delay processing method and the second embodiment of the transmission delay processing method are described in detail below by using several specific embodiments.

FIG. 3 is a schematic flowchart diagram of Embodiment 3 of a method for processing a transmission delay according to the present invention. In this embodiment, in the embodiment 1 of the transmission delay processing method and the second embodiment of the transmission delay processing method, the base station obtains the transmission delay value, and reports the transmission delay value to the radio network controller. Do a detailed description. As shown in FIG. 3, the method in this embodiment may include:

Step 301: The base station searches for an access preamble sent by the user equipment by using a first search window, where a window length of the first search window is a multiple of the quantization precision.

The user equipment sends an access preamble (Preamble) before the user equipment sends a Radio Resource Control (RRC) connection request message to the base station to establish a network connection. The base station searches for the access preamble sent by the user equipment by using the first search window. The starting position of the first search window starts from 0, and when the base station receives the access preamble sent by the user equipment, the base station stops searching. The window length of the first search window is a multiple of the quantization precision.

Step 302: The base station acquires a transmission delay value of the physical random access channel according to the window length of the first search window and the location of the search for the preamble.

After receiving the access preamble sent by the user equipment, the base station may search for the location of the access preamble according to the window length of the first search window, and use the existing physical random access channel (Physical Random Access Channel, PRACH for short). A method of transmitting a delay value to obtain a transmission delay value.

Step 303: The base station converts the transmission delay value into a transmission delay report value according to the quantization precision of the transmission delay value.

After obtaining the transmission delay value, the base station converts the transmission delay value into a transmission delay report value according to the quantization precision. In this example, the value of the quantization precision may specifically be one chip. For example, when the transmission delay value is 6.5 chips, the transmission delay value is converted into 6 chips according to the quantization precision, 6 chips are reported as transmission delays.

Step 304: The base station writes the identifier of the transmission delay report value and the quantization precision into the frame protocol packet, and reports the frame protocol packet to the radio network controller.

Step 305: The radio network controller receives the frame protocol packet sent by the base station, and parses the identifier of the transmission delay report value and the quantization precision from the frame protocol packet.

In steps 304 and 305, the identification of the quantization precision may indicate a specific value of the quantization precision. In this embodiment, the identification of the quantization precision may preferably be a transmission delay index of the quantization precision. The quantization delay transmission delay index can be written into two idle bits of the frame protocol packet, such as the two idle bits specified in the protocol (Spare 7-6). The value of the specific transmission delay index can be 3⁄4:

If the quantization precision is 1 chip, the value of the transmission delay index is 1;

Those skilled in the art can understand that the processing method of the transmission delay in this embodiment can be compatible with the processing method of the transmission delay in the prior art. When the quantization precision is 3 chips, the value of the transmission delay index may be set to 0, or the transmission delay index of the frame protocol packet does not carry the quantization precision. Those skilled in the art can understand that the base station and the radio network controller can obtain corresponding quantization precision according to the transmission delay index. In a specific implementation process, a correspondence table between the transmission delay index and the quantization precision may be stored in the base station and the radio network controller, and the base station and the radio network controller may obtain the quantization precision of the transmission delay value according to the correspondence table.

In particular, depending on the difference in quantization precision, and the difference between the reported bit of the transmission delay and the reported bit of the extended transmission delay, the base station writes the transmission delay report value to the frame protocol packet in two ways.

The reporting bit of the transmission delay is 8 bits, and the value ranges from 0 to 255, and the reporting bit of the extended transmission delay is 10 bits, and the value ranges from 255 to 1023. Therefore, one way of writing is: determining the value of the transmission delay of less than 255 XN chips as the reporting delay of the Propagation delay, and the other writing mode is: Will be greater than 255 Ν Ν The transmission delay report value of the slice is determined as the upper 4 bits of the Extended Propagation Delay, and N is the quantization precision. A person skilled in the art can understand that the transmission delay value is converted into a transmission delay report value according to the quantization precision, and the transmission delay report value is determined as the reporting bit of the transmission delay and the extended transmission. When the input delay is reported, the quantization accuracy is the same.

In this embodiment, the quantization precision is 1 chip as an example. When the quantization precision is 1 chip, the transmission delay value of less than 255 chips is determined as the reporting bit of the transmission delay, and the transmission delay value of more than 255 chips and less than 1023 chips is determined as the extended transmission delay. Report the bit. Those skilled in the art can understand that the quantization precision can also be selected according to the distance between the base station and the user equipment and the distance corresponding to the maximum value of the extended transmission delay. For example, for a super-far coverage scenario, the maximum value of the extended transmission delay corresponding to the quantization precision of 1 chip is 1023 chips, and the corresponding distance is 799.875 meters, and the distance between the base station and the user equipment is 90 kilometers, which is greater than the extended transmission time. To extend the distance corresponding to the maximum value, the quantization precision of 1.5 chips can be selected as the quantization precision of the transmission delay value. It can be understood by those skilled in the art that when the quantization precision is 1.5 chips, since the reporting delay bit and the extended transmission delay reporting bit are the same, the transmission delay report value corresponding to the transmission delay reporting bit is in the range of 0 to 382.5 chips, the transmission delay time corresponding to the extended transmission delay reporting bit ranges from 382.5 chips to 1534.5 chips, and the maximum value of the extended transmission delay corresponds to 1 19882.8125 meters, which is about 120. Kilometers, greater than 90 kilometers, indicating that the quantization accuracy of 1.5 chips is correct.

The transmission delay processing method provided in this embodiment can obtain an accurate transmission delay value of the physical random access channel by finely configuring the quantization precision, and the base station converts the transmission delay value into a transmission delay report value, and The transmission delay report value is reported to the radio network controller, so that the radio network controller can perform network optimization.

FIG. 4 is a schematic flowchart diagram of Embodiment 4 of a method for processing a transmission delay according to the present invention. In this embodiment, after the base station reports the transmission delay to the radio network controller, the base station obtains the transmission delay report value from the radio network controller, and according to the transmission, on the basis of the first to the third embodiment of the transmission delay processing method. The delay report value determines the uplink dedicated physical channel for detailed description. Meanwhile, the steps of the embodiment may optionally be performed after step 305 shown in FIG. As shown in FIG. 4, the method in this embodiment may include:

Step 401: The base station receives a transmission delay report value sent by the radio network controller.

The base station receives the radio link setup request message sent by the radio network controller, where the radio link setup request message includes an identifier for transmitting the delay report value and the quantization precision, and the base station may obtain the transmission delay report value from the radio link setup request message. And the identification of the quantization precision, and the quantization precision is determined according to the identification of the quantization precision. Preferably, the identification of the quantization precision in this embodiment is the quantization precision. The transmission delay index. In particular, a transmission delay index field of quantization precision may be added to the radio link setup request message.

Step 402: The base station determines, according to the transmission delay report value, a starting position of the second search window for searching for the multipath of the uplink dedicated physical channel, and determines the length of the second search window according to the quantization precision of the transmission delay value.

In a specific implementation process, the base station may set the transmission delay report value to search for the starting position of the uplink dedicated physical channel multipath. For example, in this embodiment, the quantization precision is 1 chip, and the transmission delay is 8 chips, and the start position of the second search window for searching the uplink dedicated physical channel is set to 8 chips. A person skilled in the art can understand that if the quantization precision of the prior art is 3 chips, if the transmission delay value is 8 chips, the transmission delay is reported as 6 chips, and the base station obtains the transmission delay reported by the RNC. The value is 6 chips and the base station sets the start position of the second search window to 6 chips.

As can be seen from the above, in this embodiment, the quantization precision of the refined configuration is used, the starting position of the search window is closer to the real position, and the search precision is higher.

Step 403: The base station searches for a multipath of the uplink dedicated physical channel in the second search window, and determines an uplink dedicated physical channel according to the search result.

The base station searches for the multipath of the uplink dedicated physical channel in the second search window. After searching for the multipath, the uplink dedicated physical channel can be determined according to the prior art. Those skilled in the art can understand that if the error of the transmission delay is large, the actual multipath will fall outside the second search window. In this embodiment, the error of the transmission delay on the transmission delay is extremely small, and the actual multipath falls within the search window, thereby improving the accuracy of the search.

The transmission delay processing method provided in this embodiment can improve the search precision of the multipath search by finely configuring the quantization precision and obtaining an accurate transmission delay value.
