In order to make the objects, technical solutions, and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below. Example 1

This embodiment provides a method for controlling uplink data transmission. For convenience of description, the terminal side performs the method provided by the embodiment of the present invention as an example. Referring to FIG. 1, the uplink data transmission control method includes: The terminal receives the identifiers of the multiple uplink time slots allocated by the network side for the terminal and a first USF, where the first USF is a unique USF allocated by the network side for multiple uplink time slots, and is in multiple uplink time slots. One upstream time slot corresponds.

The identifier of the multiple uplink time slots allocated by the network side for the terminal and the first USF may be sent to the terminal in the uplink assignment message (Packet Up), and the terminal receives the uplink assignment message sent by the network side. According to the uplink assignment message, multiple uplink time slots and a first USF allocated by the network side are obtained. Of course, the network side may further send the identifiers of the allocated multiple uplink time slots and the first USF to the terminal by using other methods. This embodiment does not specifically limit this.

102. The downlink radio block that is sent by the network side in the downlink time slot corresponding to the uplink time slot corresponding to the first USG, where the downlink radio block carries the second USF.

For this step, the first USF allocated by the network side corresponds to one uplink time slot of the allocated uplink time slots, in order to prevent the terminal from listening to the downlink time slot corresponding to each allocated uplink time slot, this embodiment In the method provided, the network side sends a downlink radio block in a downlink time slot corresponding to the uplink time slot corresponding to the first USF, and the terminal only listens to the downlink time slot corresponding to the uplink time slot corresponding to the first USF, The downlink radio block delivered by the network side is received. Therefore, terminal power can be saved compared to listening to multiple downlink time slots.

103. Perform uplink block transmission control on the allocated multiple uplink time slots according to the first USF allocated by the network side and the second USF carried in the downlink radio block.

Specifically, if the first USF is the same as the second USF, the uplink block is sent in the allocated multiple uplink time slots; if the first USF is different from the second USF, the multiple uplink time slots are allocated. Do not send upstream blocks.

This embodiment further provides another method for controlling the sending of the uplink data. For convenience of description, the method provided by the embodiment is taken as an example. Referring to FIG. 2, the method for controlling the sending of the uplink data includes:

The network side allocates a plurality of uplink time slots and a first USF to the terminal, and sends the identifiers of the multiple uplink time slots and the first USF to the terminal, where the first USF is allocated by the network side for multiple uplink time slots. A unique USF and corresponds to one of the plurality of upstream time slots.

The downlink radio slot carrying the second USF is sent in the downlink time slot corresponding to the uplink time slot corresponding to the first USG, so that the terminal allocates the second USF according to the first USF and the second USF carried in the downlink radio block. A plurality of uplink time slots perform uplink block transmission control.

Specifically, if the first USF is the same as the second USF, the terminal is configured to send an uplink block in the allocated multiple uplink time slots; if the first USF is different from the second USF, the terminal is configured to be in multiple Upstream No uplink block is sent in the time slot.

In the uplink data transmission control method provided by the embodiment, when the network side device allocates multiple uplink time slots for the terminal having the multi-slot function, only one USF is allocated to the multiple uplink time slots, so that the terminal is configured according to the network side device. The USF and the allocated USF control included in the downlink radio block that is sent are used to send the uplink block on the allocated multiple uplink time slots, and the terminal with the multi-slot function only occupies one USF, so that when the USF resources are limited, The network side can allocate the USF to more terminals, thereby increasing the number of terminals that can be accessed. In addition, the downlink radio block is sent by the network side in the downlink time slot corresponding to the uplink time slot corresponding to the first USF, so that the terminal is enabled. The downlink radio block delivered by the network side can be received only by listening to the downlink time slot, thereby saving terminal power. Example 2

Referring to FIG. 3, this embodiment provides a method for controlling uplink data transmission. In order to increase the number of terminals that can be accessed, the method uses only a plurality of uplink time slots for a terminal having a multi-slot function, and only A plurality of uplink time slots are allocated with one USF, so that the terminal can implement uplink block transmission control of multiple uplink time slots according to one USF. The method includes:

301. The terminal sends an access request message to the network side, where the access request message carries an identifier that supports uplink block sending control of multiple uplink time slots according to one USF.

The access request message sent by the terminal to the network side includes, but is not limited to, a Channel Request, a Packet Channel Request, an EGPRS Packet Channel Request message, and the like. The specific access request message sent by the terminal is not limited, and the access request message carrying terminal does not support the manner in which the identifier of the uplink block sending control of multiple uplink time slots is implemented by one USF. For example, an identifier may be added to the original field in the access request message, or a new field may be added to identify that the terminal supports uplink block transmission control for implementing multiple uplink time slots according to one USF.

The access request message sent by the terminal to the network side is an EGPRS Packet Channel Request message. When the message carrying terminal supports the identifier of the uplink block sending control of multiple uplink time slots according to a USF, the message may be in the message. The value of the Mult i slotClass field is used as an identifier to identify that the terminal supports uplink block transmission control for implementing multiple uplink time slots according to one USF. For example, if the value of the Multi slotClass field in the EGPRS Packet Channel Request message is 11 101, The identifier terminal supports the uplink block sending control of multiple uplink time slots according to one USF. Of course, the 11101 is only an exemplary value, and other values may be selected in the actual application, which is not specifically limited in this embodiment. Set.

If the terminal does not support the uplink block sending control of multiple uplink time slots according to one USF, when the terminal sends the access request message to the network side, the terminal may not carry the identifier in the access request message, or send the same in the same manner. In the case of the above-mentioned identifier, the value of the identifier is set to not support the uplink block transmission control of multiple uplink time slots according to one USF. For this case, the uplink data transmission control is the same as the prior art, and details are not described herein again. .

302. The network side receives an access request message sent by the terminal, and allocates, according to the identifier carried in the access request message, a plurality of uplink time slots and a first USF, where the first USF is a plurality of uplink time slots on the network side. The unique USF assigned and corresponding to one of the plurality of upstream time slots.

Specifically, if a USF is allocated to each uplink time slot allocated to the terminal, a large amount of USF resources are consumed. Therefore, the network side receives the uplink block supported by the terminal to implement multiple uplink time slots according to one USF. Sending an identifier of the control, according to the identifier, after the terminal supports uplink block transmission control of multiple uplink time slots according to one USF, assigning multiple uplink time slots to the terminal, and assigning a unique USF to multiple uplink time slots simultaneously The subsequent USF assigned to the terminal on the network side is referred to as a first USF. And because a plurality of uplink time slots are only assigned one USF, the first USF corresponds to one of the plurality of uplink time slots. For example, the first USF corresponds to an uplink time slot with the smallest slot number, or corresponds to an uplink time slot with the largest slot number, or corresponds to other uplink time slots, and which uplink time is used by the first USF. Corresponding to the gap, this embodiment does not specifically limit this.

It should be noted that, in the foregoing step 301 and step 302, the network side can accurately know whether the terminal supports the uplink block sending control of multiple uplink time slots according to one USF when the network side performs the transmission control of the uplink data, if the network side has obtained If the terminal supports the uplink block transmission control of multiple uplink time slots according to one USF, the above steps 301 and 302 may be omitted.

303. The network side terminal sends an uplink assignment message, where the uplink assignment message includes an identifier of the multiple uplink time slots allocated by the network side for the terminal, and a first USF.

Specifically, since the network side knows that the terminal supports the uplink block sending control of multiple uplink time slots according to one USF through the foregoing steps 301 and 302, the network side allocates multiple uplink time slots and one first for the terminal. After the USF, it is sent to the terminal through the uplink assignment message, so that the terminal knows the multiple uplink time slots and the first chaos that are allocated.

In the specific implementation, the time slot and the first USF may be allocated to the terminal in the <0 11 & 111 Al locati on struct > field in the uplink assignment message. Since the USF field is 3, a maximum of 8 USF values can be allocated, but in the existing protocol. A value is reserved, which is not used to debug any terminal, such as USF equals 7, now When the USF value in the row radio block header is 7, it indicates that the corresponding uplink block has been reserved, and no terminal is scheduled. When the terminal is assigned the value in the uplink assignment message, it indicates that the terminal does not need to allocate the USF value on the uplink channel. The network side allocates time slots 0, 1, and 3 times as an example. The time slot 0 allocates an available USF value 2 to the terminal, and assigns one terminal to the terminal in time slot 1 and time slot 2. The USF value used, such as 7. In addition, when the network side sends an uplink assignment message to the terminal, the network may add an indication identifier to the original field in the information or add a new field to indicate that the terminal performs the uplink according to the method in this embodiment. Transmission control of data.

304. The terminal receives an uplink assignment message sent by the network side, and obtains, according to the uplink assignment message, identifiers of multiple uplink time slots allocated by the network side and a first USF.

Specifically, the terminal receives the uplink assignment message sent by the network side, and the identifier of the multiple uplink time slots allocated by the network side to the terminal is a first USF. Therefore, after receiving the uplink assignment message sent by the network side, the terminal may The first USF allocated to the network side and the first USF allocated to the multiple uplink time slots are corresponding to the uplink time slot with the smallest serial number. For example, refer to FIG. 5, the network side. The uplink time slots allocated for the terminal are uplink time slot 1, uplink time slot 2, and uplink time slot 3, and the three uplink time slots sequentially correspond to the uplink PDCH (Packet Data Channe l), the uplink PDCHj, and the uplink PDCHk. The first USF allocated to the three uplink time slots on the network side corresponds to the uplink time slot 1 as an example.

305. The network side sends a downlink radio block in a downlink time slot corresponding to the uplink time slot corresponding to the first USG, where the downlink radio block carries the second USF.

For this step, after the network side allocates multiple uplink time slots to the terminal, only one USF is allocated to the multiple uplink time slots. Therefore, when the network side sends the downlink wireless block, only one USF needs to be carried in the wireless block. In order to reduce the number of the terminal monitoring time slots, the network side sends a downlink radio block in the downlink time slot corresponding to the uplink time slot corresponding to the first USF, and the downlink wireless mode is adopted. If the block carries the second USF, the terminal may perform uplink block transmission control on multiple uplink time slots according to whether the first USF and the second USF carried in the downlink radio block are the same. The specific control manner is as follows.

Optionally, in order to further refine the manner in which the terminal performs uplink block transmission control on multiple uplink time slots according to a USF, the downlink wireless block sent by the network side may further carry a sending identifier, where the sending identifier is used, according to a specific application scenario. The terminal is instructed to send an uplink block in multiple uplink time slots or to identify the terminal to send an uplink block in one uplink time slot. In a specific implementation, the sending identifier may be a sending indication value, and the structure diagram of the downlink radio block shown in FIG. 4 is taken as an example, in a BSN (Block Sequence Number), FBI (Final Block Indicator, last block means no), payload, spare, S/P (Supplementary Block/Poll), RRBP (Relative Reserved Block Period), etc. The value may be carried in the payload field or the spare field or other fields in the downlink radio block. In addition, the combined value of the two fields S/P and RRBP may be used as the sending indication value to indicate that the terminal is in an uplink time slot. The uplink block is sent on the uplink block or the uplink block is sent on multiple uplink time slots. This embodiment does not limit the carrying position of the transmission indication value. For example, when the S/P value is 0, the RRBP field is used to indicate whether the terminal sends an uplink block on an uplink time slot or an uplink block on multiple uplink time slots, for example, an S/P value of 0, an RRBP field. When it is 00, it indicates that the terminal sends the uplink block only on one uplink time slot. When the RRPB field is 01, it indicates that the terminal sends the uplink block on multiple uplink time slots. Of course, the value here is only an example, and other values may be taken in the actual application, or other manners may be used as the sending identifier.

306. The terminal monitors a downlink time slot corresponding to the uplink time slot corresponding to the first USF, and receives a downlink wireless block that is sent by the network side through the downlink time slot.

Specifically, since the network side sends the downlink radio block in the downlink time slot corresponding to the uplink time slot corresponding to the first USG, the terminal does not need to monitor the downlink time slot corresponding to each allocated uplink time slot, but only needs to monitor and The downlink time slot corresponding to the uplink time slot corresponding to the first USF may be used. For example, the first USF allocated by the network side in the foregoing step 304 corresponds to the uplink time slot with the smallest sequence number among the multiple uplink time slots allocated by the network side, and in this step, the terminal only needs to monitor the uplink with the smallest sequence number. The downlink time slot corresponding to the time slot is received, and the downlink wireless block sent by the network side in the downlink time slot is received. For example, in Figure 5, the terminal listens to the downlink radio block transmitted by the network side in the downlink time slot 1. Of course, if the first USF allocated on the network side corresponds to the uplink time slot 2 in FIG. 5, in this step, the terminal can listen to the downlink time slot 2 and receive the downlink sent by the network side in the downlink time slot 2. And the radio block, so that the uplink data transmission control is performed on the plurality of uplink time slots according to the allocated first USF and the second USF carried in the downlink radio block.

307. The terminal performs uplink block transmission control on the allocated multiple uplink time slots according to the allocated first USF and the second USF carried in the downlink radio block.

Specifically, according to the content carried in the downlink radio block received by the terminal in step 306, the manner in which the terminal performs uplink block transmission control on multiple uplink time slots is divided into the following two situations:

Situation one

When the downlink radio block carries the second USF delivered by the network side and does not carry the transmission identifier, if the second USF sent by the network side is the same as the first USF pre-allocated by the network side, the terminal is allocated more. The uplink block is sent on the uplink time slot; if the second USF and the network are sent by the network side The first USF that is pre-allocated on the network side is different, and the terminal does not send the uplink block in multiple uplink time slots allocated. Taking the situation 1 shown in FIG. 5 as an example, the uplink time slots allocated by the network side for the terminal are uplink time slot 1, uplink time slot 2, and uplink time slot 3, and the three uplink time slots sequentially correspond to the uplink PDCHi, the uplink PDCHj, and the uplink. PDCHk, the first USF allocated by the network side for the three uplink time slots corresponds to the uplink time slot 1, and the value is X. Because the downlink radio block sent by the network side in the downlink time slot 1 carries the second USF sent by the network side, the terminal monitors the downlink time slot 1 and receives the downlink radio block sent by the network side in the downlink time slot 1. The second USF is sent by the network side. If the second USF value carried in the downlink radio block sent by the network side is also X, the terminal sends the uplink time slot 1, the uplink time slot 2, and the uplink time slot 3. If the second USF value carried in the downlink radio block delivered by the network side is non-X, the terminal does not send the uplink block in the uplink time slot 1, the uplink time slot 2, and the uplink time slot 3.

Situation 2

When the downlink radio block carries the second USF and the sending identifier sent by the network side, if the second USF sent by the network side is different from the first USF allocated by the network side, the terminal allocates multiple uplinks on the network side. The uplink block is not sent on the network side; if the second USF sent by the network side is the same as the first USF pre-allocated on the network side, when the sending identifier indicates that the uplink block is sent in multiple uplink time slots, the terminal allocates multiple on the network side. The uplink block is sent on the uplink time slot; when the transmission identifier indicates that the uplink block is sent in an uplink time slot, the terminal sends the uplink block in the uplink time slot allocated to the USF.

Taking case 2 shown in FIG. 6 as an example, the uplink time slots allocated by the network side for the terminal are uplink time slot 1, uplink time slot 2, and uplink time slot 3, and the three uplink time slots sequentially correspond to uplink PDCHi, uplink PDCHj, and uplink. PDCHk, the first USF allocated by the network side for the three uplink time slots corresponds to the uplink time slot 1, and the value is X. The downlink radio block sent by the network side in the downlink time slot 1 includes the second USF and the transmission identifier sent by the network side, and the terminal only needs to listen to the downlink time slot 1 and receive the downlink radio block sent by the network side in the downlink time slot 1 And parsing the downlink radio block sent in the downlink time slot 1 to obtain the second USF and the sending identifier sent by the network side, if the second USF value sent by the network side is also X, when the sending identifier indicates that the number is When the uplink time slot transmits the uplink block (that is, the transmission indication value is 1), the terminal sends the uplink block in the uplink time slot 1, the uplink time slot 2, and the uplink time slot 3; when the sending identifier indicates that the uplink block is sent in an uplink time slot. When the uplink block (that is, the transmission indication value is 0), the terminal transmits the uplink block only on the uplink time slot 1. The value of the indication value sent here is only an example function, and other values can be taken as well.

When the present embodiment is implemented, the terminal only listens to the downlink time slot of the downlink radio block, that is, only the downlink time slot corresponding to the uplink time slot corresponding to the first USF, and does not need to monitor and allocate all the uplinks. The downlink time slot corresponding to the time slot, therefore, the power of the terminal can be saved. In the uplink data transmission control method provided by the embodiment, when the network side device allocates multiple uplink time slots for the terminal having the multi-slot function, only one USF is allocated to one of the uplink time slots, and the terminal is configured according to the network side device. The USF and the allocated USF control included in the downlink radio block are sent to send uplink blocks on one or more uplink time slots, and the terminal with multi-slot function only occupies one USF, so that when the USF resources are limited, The network side can allocate the USF to more terminals, thereby increasing the number of terminals that can be accessed. In addition, the downlink radio block is sent by the network side in the downlink time slot corresponding to the uplink time slot corresponding to the first USF, so that the terminal only The downlink radio block that is sent by the network side can be received by monitoring the downlink time slot, thereby saving terminal power. Example 3

The second receiving module 702 is configured to receive a downlink radio block that is sent by the network side in a downlink time slot corresponding to the uplink time slot corresponding to the first USG, where the downlink radio block carries the second USF.

The control module 703 is configured to perform uplink block transmission control on the allocated multiple uplink time slots according to the first USF allocated by the network side and the second USF carried in the downlink radio block.

The first receiving module 701 can receive the uplink time slot and the first USF allocated by the network side, and the network side can carry it in the uplink assignment message, and the first receiving module 701 can receive the network side. The uplink assignment information is sent, and the identifier of the multiple uplink time slots allocated by the network side and a first USF are obtained according to the uplink assignment information. For details, refer to the description of step 101 in the first embodiment, and the foregoing embodiment 2. Description of steps 303 and 304.

For details of the manner in which the second receiving module 702 receives the downlink radio block delivered by the network side, refer to the related descriptions of step 305 and step 306 in the second embodiment.

Specifically, the control module 703 is specifically configured to: if the first USF and the second USF are the same, send the uplink block in the allocated multiple uplink time slots; if the first USF and the second USF are different, the multiple uplinks are allocated. No uplink block is sent in the time slot.

In the process of implementing the embodiment, if the downlink radio block received by the second receiving module 602 further carries the sending identifier, the control module 703 is specifically configured to: if the first USF and the second USF are the same, and send the label If the uplink block is sent in multiple uplink time slots, the uplink block is sent in multiple uplink time slots; if the first USF and the second USF are the same, and the sending identifier indicates that the uplink block is sent in one uplink time slot, The uplink block is sent in an uplink time slot corresponding to the first USF; if the first USF and the second USF are not the same, the uplink block is not sent in the allocated multiple uplink time slots.

For details of the control mode of the control module 703, refer to the related description of the step 307 in the second embodiment.
