The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Embodiment 1

Referring to FIG. 1, this embodiment provides a method for controlling a dynamic slot reduction mode, and the method is specifically as follows:

1 01: Determine the amount of data to be processed by the terminal device in DTR mode;

1 02: The corresponding DTR control indication is sent to the terminal device according to the determined data volume size, so that the terminal device exits or maintains the DTR mode according to the DTR control indication.

In this embodiment, the data to be processed by the terminal device refers to data that the terminal device needs to transmit to the network side device, or data that the network side device needs to send to the terminal device.

This embodiment can be implemented on a network side device, such as a base station controller. The data that the terminal device needs to transmit to the base station controller is sent by using the uplink TBF, and the data that the base station controller needs to transmit to the terminal device can be sent by using the downlink TBF.

On the network side, the amount of data to be processed by the terminal device may be determined according to the amount of data to be transmitted by the terminal device, or the amount of data to be processed by the terminal device.

The terminal device may notify the network side device to report the amount of data to be transmitted through separate signaling. The first uplink data block or the empty data block that is sent may also carry the amount of data to be transmitted.

The DTR control indication may include: instructing the terminal device to exit the DTR mode and enter the normal mode, or instructing the terminal to maintain the DTR mode.

If the amount of data to be processed is large, the network side device sends the exit DT mode to the terminal device, enters the normal mode, and receives or sends data. If the amount of data to be processed is small, the network side device instructs the terminal device to continue to maintain the DTR mode. The terminal device receives data in DT mode.

The solution in this embodiment can be applied to services that are not very demanding in real-time and have a relatively small amount of data transmission, for example, various timely short message services, including QQ services and Fetion services.

The method provided in this embodiment determines the amount of data to be processed by the terminal device, and according to The terminal sends a corresponding DTR control indication to the terminal device, so that the terminal device selects to exit or maintain the DTR mode according to the DTR control indication sent by the network side device, so that the terminal device does not need to exit the DTR mode every time the data is processed, and further Improve the power saving efficiency of the terminal equipment. Embodiment 2

This embodiment provides a method for controlling a dynamic slot reduction mode. The data transmission mode is divided into an uplink TBF direction and a downlink TBF direction. For convenience of description, this embodiment first sends a terminal device in the DTR mode in the TBF direction. The uplink data is taken as an example, and the method provided in this embodiment is described in detail. Referring to FIG. 2, the method provided by this embodiment is as follows:

201: The terminal device sends the uplink data on the corresponding time slot monitored in the DTR mode, and reports the data volume;

In this embodiment, the method for limiting the amount of data on the terminal device is not limited, including but not limited to: the terminal device may carry the amount of data sent by the terminal device by using parameters in the sent data block header, for example, by EGPRS Up l. The parameter CV ( Countdo 丽 Va lue ) in the ink RLC (Radio Link Control)/MAC (Media Acces s Control) header carries the amount of data transmitted by the terminal device, the parameter CV It is used by the terminal device to indicate the number of RLC data blocks that the terminal device is ready to transmit in the current uplink TBF direction.

In addition, the terminal device may determine whether to exit the DTR mode or maintain the DTR mode according to the data amount of the uplink data that is actually needed, and send a corresponding DTR mode request to the network side device, so that the network side device is in the DTR mode. Under the trigger of the request, the corresponding DTR control indication is sent according to the amount of data reported by the terminal device.

The manner in which the terminal device sends a request to the network side device includes, but is not limited to, adding an identifier in the data block or the block header, which is not specifically limited in this embodiment. For example, a request indication bit DTR Reques t is added to the uplink HLC data block sent by the terminal device to the network side device, and when the indication bit is 0, it is used to request the network side device. Exiting the DTR mode; when the indicator bit is 1, it is used to request the network side device to continue to maintain the DTR mode. As a show For example, the indicator bit can be an idle bit in the header of the data block, which is 2 bits.

The amount of data reported by the terminal device and the DTR mode request may be sent in the same data block or signaling, or may be sent in different data blocks or signaling.

202: The network side device determines, according to the amount of data reported by the terminal device, the amount of data to be processed by the terminal device, and sends a corresponding DTR control indication to the terminal device according to the determined data volume size, so that the terminal device exits or maintains according to the DTR control indication. DTR mode.

For this step, in order to effectively control the DTR mode of the terminal device, after determining the amount of data to be processed by the terminal device, the network-side device may send the data to the terminal device after determining that the determined data volume reaches a preset threshold. Corresponding DTR control indication.

For example, the network side device first determines whether the determined data volume size reaches a preset threshold; if yes, sends a DTR control indication that exits the DTR mode to the terminal device;

If not, the DTR control indication for maintaining the DTR mode is issued to the terminal device.

In this embodiment, the preset threshold is not specifically limited. In an actual application, an empirical value may be used. If the network side device determines that the determined data volume is smaller than the network experience value, the network side device sends the DTR to the terminal device. The DTR control indication of the mode is used to indicate that the terminal device continues to maintain the DTR mode; if the network side device determines that the determined data volume size is greater than the network experience value, the network side device sends a DTR control indication that exits the DTR mode to the terminal device, where Indicates that the terminal device exits the DTR mode.

Alternatively, the network side device may also determine whether to exit the DTR mode or maintain the DTR mode in combination with the service type.

Regarding the manner in which the network side device sends the DTR control indication, the present embodiment does not specifically limit this. Since the network side device needs to send a PACKET UPLINK ACK/NACK message to the terminal device, the network side device sends the DTR control to the terminal device. The instructions include but are not limited to the following two ways:

1) carrying the DTR control indication through the parameters in the PACKET UPLINK ACK/NACK message; for example, in the PACKET UPLINK ACK/NACK inf ormat ion cell, the parameter CI_DTR, TN-PDCH- pa ir- DTK, DTR B l ks is valid.

Wherein the parameter is used to indicate CI _DTR carrier terminal device needs to monitor the parameter TN_PDCH_ _P air _ DT slot is used for indicating the terminal device need to be monitored, the parameter block for DTK B l ks cycle indicating terminal device needs to be monitored, three The value of the parameter may be the same as the value when the terminal device enters the DTR mode, or may be different, which is not specifically limited in this embodiment.

2) Carry the DTR control indication by adding an indicator bit to the PACKET UPL INK ACK/NAC message.

For example, an indication bit DTR S tay is added to the PACKET UPL INK ACK/NACK message. When the indication bit is 0, it is used to indicate that the terminal device exits the DTR mode. When the indication bit is 1, it is used to indicate that the terminal device continues. Keep the DTR mode.

In the following TLF direction, the network side device needs to send downlink data to the terminal device in the DTR mode as an example to further explain the method provided in this embodiment. Referring to FIG. 3, the process of the method provided in this embodiment is specifically as follows:

301: Before sending the downlink data to the terminal device in the DTR mode, the network side device determines the amount of data to be sent to the terminal device, and determines the amount of data to be processed by the terminal device according to the amount of data to be sent to the terminal device.

If the network side device needs to send data to the terminal device, the amount of data sent by the network side device is the amount of data to be processed by the terminal device. Therefore, the network device can determine the terminal device to be sent according to the amount of data to be sent to the terminal device. The amount of data processed.

302: The network side device sends a corresponding DTR control indication to the terminal device according to the determined data volume size, so that the terminal device exits or maintains the DTR mode according to the DTR control indication.

After determining the amount of the data to be processed by the terminal device, the network side device may also send the corresponding DTR control indication to the terminal device after determining that the determined data volume reaches the preset threshold, as described in step 202 above. , will not repeat them here.

The network side device may carry the corresponding DTR control indication in the sent data. The DTR control indication may also be sent in a separate signaling. For example, if the determined amount of data is smaller than the preset threshold, that is, the amount of data to be processed by the terminal device is small, the network side device carries the DTR control indication in the block header or the data portion of the first data block in the sent downlink data. Instructing the terminal to maintain the DTR mode, the terminal device is in the DTR mode before receiving the data block, and after receiving the data block, continues to maintain the DTR mode without going to the normal mode.

If the determined amount of data is greater than the preset threshold, that is, the amount of data to be processed by the terminal device is large, the network side device does not carry the DTR control indication in the block header or the data portion of the first data block in the sent downlink data, or Setting the cell value corresponding to the DTR control indication to 0, causing the terminal device to exit the DTR mode, the terminal device is in the DTR mode before receiving the data block, and after receiving the data block, exits the DTR mode and enters the normal mode, and Continue to receive data through the downstream TBF connection.

In addition, the network side device may also issue the DTR control indication in other manners, which is not specifically limited in this embodiment. For example, if the determined amount of data is smaller than the preset value, the first data block of the downlink data sent by the network side device does not add an indication for indicating that the terminal device maintains the DTR mode; instead, if the determined data size If the value is greater than the preset threshold, the network side device adds an indication to the first data block in the sent downlink data, and is used to indicate that the terminal device exits the DTR mode after receiving the data block.

In the method provided by the embodiment, the network device determines the size of the data to be processed by the terminal device, and sends a corresponding DTR control indication to the terminal device, so that the terminal device selects to exit according to the DTR control indication sent by the network device. Or maintaining the DTR mode, so that the terminal device does not need to exit the DTR mode every time data is processed, so as to improve the power saving efficiency of the terminal device; in addition, the terminal device selects to send the DTR to the network side device according to the situation of processing the data by itself. The mode request increases the flexibility of the terminal device while improving the power saving efficiency of the terminal device. Embodiment 3
