Description

Method and device for data transmission

The present invention relates to the field of communications, and in particular, to a method and apparatus for data transmission. Background technique

HSDPA (High Speed Downlink Packet Access:) is a mobile communication protocol for data transmission.

The data transmitted using the HSDPA protocol is called HSDPA data. HSDPA data needs to go through the HSDPA service setup and capacity allocation process before it can be transmitted. In the capacity allocation process, the RNC (Radio Network Controller) sends a capacity request control frame to the base station, and the capacity request control frame is used to request bandwidth resources from the base station. After receiving the capacity request control frame sent by the RNC, the base station sends a capacity allocation control frame to the RNC to allocate bandwidth resources to the RNC.

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 flowchart of a method for data transmission according to an embodiment of the present invention. Referring to FIG. 1, an embodiment of the present invention provides a data transmission method, where the method is described based on an RNC, and includes:

11. The RNC sends a capacity request control frame to the base station, where the capacity request control frame is used to request bandwidth resources from the base station.

In the embodiment of the present invention, the RNC may request a bandwidth resource from the base station by sending a capacity request control frame to the base station, and correspondingly, after receiving the capacity request control frame, the base station may The RNC responds to the capacity allocation control frame to allocate bandwidth resources to the RNC.

12. The RNC determines whether a capacity allocation control frame sent by the base station is received within a preset time after transmitting the capacity request control frame.

The preset time can be set as needed, for example, 400 ms, etc., and the present invention does not limit this.

After transmitting the capacity request control frame, the RNC waits for the base station to respond to the capacity allocation control frame. The RNC may use different processing methods for data transmission according to whether the capacity allocation control frame received by the base station is received within a preset time.

13. If the capacity allocation control frame sent by the base station is not received within a preset time after sending the capacity request control frame, the RNC uses the pre-acquired initial capacity allocation. The bandwidth specified by the information is used for HSDPA data transmission, or DCH data transmission is performed by using a pre-established DCH (Dedicated Channel).

The initial capacity allocation information is used to specify a bandwidth of data transmission.

The manner in which the RNC obtains the initial capacity allocation information may be: the RNC receives a message sent by the base station that carries the initial capacity allocation information, where the initial capacity allocation information is used to specify the bandwidth of the data transmission.

In this embodiment of the present invention, the message may be a RadioLink Reconfiguration Ready message or a RadioLink Setup Response message. The initial capacity allocation information is carried in a RadioLink Reconfiguration Ready message or a RadioLink Setup Response message. Specifically, if the HSDPA service is directly established, the message is a RadioLink Reconfiguration Ready message; if the HSDPA service DRD (Directed Retry Decision) is established, the message is RadioLink Setup. Response (Radio Link Setup Response:) message.

After receiving the message carrying the initial capacity allocation information, the RNC may parse the message to obtain the initial capacity allocation information carried in the message.

In addition, in the embodiment of the present invention, before the data transmission, the mobile station establishes a DCH with the wireless network, and in the process, the DCH is also established between the RNC and the base station. Specifically, before performing data transmission, the RNC may send a RadioLink Setup Request message to the base station, and after receiving the RadioLink Setup Request message, the base station may respond to the RNC with a RadioLink Setup Response ( The radio link setup response message, in this way, after the above process, the establishment of the DCH between the RNC and the base station can be completed.

14. If the capacity allocation control frame sent by the base station is received within a preset time after sending the capacity request control frame, the RNC performs HSDPA data transmission by using the bandwidth specified by the capacity allocation control frame.

When the capacity request control frame and the capacity allocation control frame are transmitted between the RNC and the base station, processing errors may occur in the RNC, the base station, or the transmission network between them. These processing errors include: 1) The RNC fails to correctly transmit the capacity request control. 2) The base station fails to correctly receive the capacity request control frame sent by the RNC; 3) the base station fails to correctly transmit the capacity allocation control frame; 4) the transmission network transmits a packet loss or a wrong packet. These errors will eventually cause the RNC to fail to receive the capacity allocation frame correctly. As a result, the RNC data cannot be sent, resulting in downlink data transmission. Interrupt, causing a sudden drop in traffic or even a web page that cannot be opened. The data transmission method provided by the embodiment of the present invention, when the RNC does not receive the capacity allocation control frame sent by the base station, performs HSDPA data transmission by using the bandwidth specified by the initial capacity allocation information or performs DCH data transmission by using the DCH, thereby avoiding The problem that the RNC data cannot be delivered due to the failure of the RNC to correctly receive the capacity allocation frame can effectively prevent the downlink data transmission from being interrupted.

Optionally, in an embodiment of the data transmission method of the present invention, when the HSDPA data transmission is performed by using the foregoing step 13 or step 14, in addition to the steps 11 to 14, the method may further include:

If the HSDPA data transmission is abnormal, the RNC uses the pre-established DCH for data transmission.

Specifically, if the RNC performs HSDPA data transmission by using the bandwidth specified by the capacity allocation control frame or performs HSDPA data transmission by using the bandwidth specified by the initial capacity allocation information, the RNC may determine the HSDPA data by: Whether the transmission is abnormal: the RNC determines whether the downlink data can be sent to the base station, and if the downlink data cannot be sent to the base station, determines that the HSDPA data transmission is abnormal, and if the downlink data can be sent to the base station, determines the HSDPA data transmission. No exception occurred.

When the HSDPA data transmission is abnormal, the data transmission method provided by the embodiment of the present invention can not only ensure normal data transmission, but also determine a network device that fails during HSDPA data transmission.

In another embodiment of the method for data transmission of the present invention, optionally, the RNC does not receive the capacity allocation control frame sent by the base station within the preset time after sending the capacity request control frame. In addition to steps 11-14, the method may further include:

The RNC determines a failed network device;

The RNC reports the faulty network device to the network management system.

In this way, after the network management system learns the faulty network device, it can prompt the user for the faulty network device, and then the user can repair the faulty network device. A, if the number of the RNC transmission capacity request control frames is zero, determining that the failed network device is an RNC;

The following four cases of A, B, C, and D are further explained.

In case A, the RN C may count the number of capacity request control frames sent to the base station, and further determine the number of capacity request control frames sent to the base station. If the number of capacity request control frames sent by the RNC is zero, it indicates that the RNC does not correctly send the capacity request control frame, and the fault occurs in the RNC processing.

In the case of B, the RNC may perform statistics on the number of capacity request control frames sent to the base station, and further determine the number of capacity request control frames sent to the base station. At the same time, the base station may perform statistics on the number of the received capacity request control frames, and then notify the RNC of the statistical result of the number of the received capacity request control frames by using a message carrying the statistical result. The number of capacity request control frames received by the base station can be determined. If the number of the RNC transmission capacity request control frames is greater than zero, and the number of capacity request control frames received by the base station is zero, it indicates that the capacity request control frame is lost during the downlink transmission, and the failure occurs in the transmission device.

In the case of the C case and the D case, the base station may perform statistics on the number of the transmission capacity allocation control frames, and further notify the RNC of the statistics result of the number of transmission capacity allocation control frames by receiving the statistical result. The message can determine the number of transmission allocation control frames transmitted by the base station. If the number of capacity allocation control frames sent by the base station is zero, it indicates that the base station does not correctly send the capacity allocation control frame, and the fault occurs in the processing of the base station. If the number of capacity allocation control frames sent by the base station is greater than zero, it indicates that the capacity allocation control frame is lost during the uplink transmission, and the failure occurs in the transmission device.

22. The RNC acquires the initial capacity allocation information carried in the message.

Specifically, after receiving the message carrying the initial capacity allocation information, the RNC may parse the message, and obtain the initial capacity allocation information carried in the message.

It is to be understood that steps 11 and 12 are performed during the preparation phase prior to data transmission. After the data transfer is ready, the capacity allocation process can be performed.

23. The RNC sends a capacity request control frame to the base station, where the capacity request control frame is used to request a bandwidth resource from the base station.

24. The RNC determines whether a capacity allocation control frame sent by the base station is received within a preset time after transmitting the capacity request control frame.

After transmitting the capacity request control frame, the RNC waits for the base station to respond to the capacity allocation control frame. The RNC may perform different HSDPA data transmissions according to a capacity allocation control frame that is received by the base station in a preset time.

25. If the capacity allocation control frame sent by the base station is not received within a preset time after sending the capacity request control frame, the RNC uses the initial capacity allocation signal, the packet, and the specified bandwidth to perform HSDPA. data transmission.

26. If the capacity allocation control frame sent by the base station is received within a preset time after sending the capacity request control frame, use the bandwidth specified by the capacity allocation control frame to enter HSDPA data transfer.

The problem that the RNC data cannot be delivered due to the capacity allocation frame can effectively prevent the downlink data transmission from being interrupted.

Correspondingly, the embodiment of the present invention further provides a data transmission method, where the method is described based on a base station, and includes:

In addition, when the HSDPA data transmission is abnormal, the data transmission method provided by the embodiment of the present invention not only ensures normal data transmission, but also determines a network device that fails during HSDPA data transmission. In another embodiment of the present invention, the method may further include:

The following four cases of A, B, C, and D are separately explained.

In the case of A, the RN C may perform statistics on the number of request control frames sent to the base station, and may inform the base station of the statistical result of the number of the request control frames by using a message. The base station can determine the number of the RNC transmission capacity request control frames by receiving the message carrying the statistical result. If the number of the RNC transmission capacity request control frames is zero, it indicates that the RNC does not correctly send the capacity request control frame, and the failure occurs in the RNC processing.

In the case of B, the RNC may perform statistics on the number of request control frames sent to the base station, and may notify the base station by using a message to send statistics of the number of request control frames, and the base station carries the statistical result by receiving The message can determine the number of RNC transmission capacity request control frames. At the same time, the base station can count the number of received capacity request frames. If the number of RNC transmission capacity request control frames is greater than zero, and the number of capacity request control frames received by the base station is zero, it indicates that the capacity request control frame is lost during downlink transmission, and the failure occurs in the transmission device.

In the case of C and D, the base station can count the number of capacity allocation control frames transmitted to the RNC. If the number of capacity allocation control frames sent by the base station is zero, it indicates that the base station does not correctly send the capacity allocation control frame, and the fault occurs in the processing of the base station. If the number of capacity allocation control frames sent by the base station is greater than zero, it indicates that the capacity allocation control frame is lost during the uplink transmission, and the failure occurs in the transmission device. The data transmission method provided by the embodiment of the present invention performs HSDPA data transmission by using the bandwidth specified by the initial capacity allocation information or DCH data transmission by using the DCH, thereby avoiding the RNC data caused by the RNC failing to correctly receive the capacity allocation frame.

In order to better understand the present invention, the present invention will be further described by way of specific examples. It is also to be noted that the embodiments exemplified below are only a part of the embodiments of the present invention, and those skilled in the art can easily conceive other embodiments, which are within the scope of the present invention.

FIG. 3 is a specific flowchart of a method for data transmission provided by an embodiment of the present invention. Referring to FIG. 3, the present embodiment provides a data transmission method capable of preventing downlink data transmission interruption due to incorrect reception of a capacity allocation frame. The data transmission method provided in this embodiment may include:

31. The RNC sends a RadioLink Setup Request message to the base station. After receiving the RadioLink Setup Request message, the base station sends a RadioLink Setup Response message to the RNC to complete establishment of a DCH between the RNC and the base station.

33. The base station sends a message carrying initial capacity allocation information to the RNC, where the initial capacity allocation information is used to specify a bandwidth for performing data transmission to the RNC. The message may be a RadioLink Reconfiguration Ready message or a RadioLink Setup Response message.

34. The RN C receives a message that is sent by the base station and carries initial capacity allocation information, and acquires the initial capacity allocation information carried in the message.

35. The RNC sends a capacity request control frame to the base station.

After receiving the capacity request control frame, the base station sends a capacity allocation control frame to the RNC, where the capacity allocation control frame is used to specify a bandwidth for data transmission to the RNC.

37. The RNC determines whether a capacity allocation control frame sent by the base station is received within a preset time when the capacity request control frame is sent. If the capacity allocation control frame sent by the base station is not received within the preset time, steps 381 and 382 are performed; if the capacity allocation control frame sent by the base station is received within the preset time, then execution is performed. Step 39.

381. The RNC performs HSDPA data transmission by using a bandwidth specified by the initial capacity allocation information or performs DCH data transmission by using a pre-established DCH.

382. The RNC determines a faulty network device, and sends the faulty network device to the network management system.

C. If the number of the capacity allocation control frames sent by the base station is zero, determining that the faulty network device is the base station; D. If the number of capacity allocation control frames sent by the base station is greater than zero, determine that the failed network device is a transmission device between the RNC and the base station.

39. If the capacity allocation control frame sent by the base station is received within the preset time, the RNC uses the bandwidth specified by the capacity allocation control frame to perform HSDPA data transmission.

It should be noted that, in this embodiment, if the RNC performs HSDPA data transmission, the RNC may determine whether an abnormality occurs in the HSDPA data transmission during the HSDPA data transmission.

The HSDPA data transmission includes HSDPA data transmission by using a bandwidth specified by the capacity allocation control frame, and HSDPA data transmission by using a bandwidth specified by the initial capacity allocation information;

In the embodiment of the present invention, if the RNC does not receive the capacity allocation control frame sent by the base station, the RNC may preferentially use the bandwidth specified by the initial capacity allocation information to send the HSDPA data. If the data transmission is normal, the RNC always uses the initial capacity allocation information. The specified bandwidth is used to send HSDPA data. If the RNC receives the capacity allocation control frame sent by the base station, the RNC uses the bandwidth indicated by the capacity allocation control frame to transmit the HSDPA data.
