The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention. As shown in FIG. 1 , a method for allocating a service channel according to an embodiment of the present invention is specifically as follows.

101. Select an available idle channel that matches the type of the access service according to the type of the access service.

 The type of the access service mainly includes a voice service and a data service. The voice service may include: a voice call service; the data service may include: web browsing, instant messaging, data downloading, video, audio, and the like.

 The available idle channel refers to an idle channel with a normal channel state and capable of carrying a service. For example, an idle channel is unavailable in the case of a blocked state or a failure, and cannot carry traffic. Therefore, when channel allocation is performed, an available idle channel is selected for allocation. The available idle channel that matches the type of the access service refers to an available idle channel capable of carrying the access service. For example, when the type of the access service is a voice service, the available idle channel that matches the type of the access service may include an available idle voice channel, and may also include an available voice service capable of carrying voice services after channel type conversion. Idle data channel or signaling channel.

 102. Obtain a time slot condition of the multi-carrier transmit channel of the available idle channel.

 The time slot condition of the multi-carrier transmitting channel includes at least one of a slot occupancy state of the multi-carrier transmitting channel, a carrier slot occupancy state of the multi-carrier transmitting channel, and a slot output power of the multi-carrier transmitting channel. The details are as follows.

 The time slot occupied state of the multi-carrier transmit channel refers to the occupied state of the same time slot of all carriers on the multi-carrier transmit channel; when the same time slot of at least one carrier on the multi-carrier transmit channel is occupied The time slot occupation status of the multi-carrier transmission channel of the same time slot is occupied; when the same time slot of all carriers on the multi-carrier transmission channel is not occupied, the same time slot The slot occupancy status of the multi-carrier transmit channel is unoccupied.

For example, it is assumed that the multi-carrier single board includes a first multi-carrier transmission channel and a second multi-carrier transmission channel, and each of the multi-carrier transmission channels is configured with three carriers, which are a first carrier, a second carrier, and a third carrier, respectively. There are two available idle channels that match the type of access service obtained in step 101, and both are on the first multi-carrier transmit channel. Wherein the first available idle channel is on the 2 slots of the first carrier, The second available idle channel is on the 3 slots of the second carrier, and the slot occupancy status of the multi-carrier transmit channel of the available idle channel refers to 2 slots and 3 slots on the first multi-carrier transmit channel. If the time slot of the at least one carrier of the first multi-carrier transmission channel is already occupied, the time slot occupation status of the multi-carrier transmission channel of the first available idle channel is occupied; The two slots of the three carriers on the multi-carrier transmit channel are unoccupied. Then, the slot occupancy status of the multi-carrier transmit channel of the first available idle channel is unoccupied.

 The slot output power of the multi-carrier transmit channel refers to the sum of the slot output powers of all the carriers on the multi-carrier transmit channel, and the slot output power of the multi-carrier transmit channel can be calculated by using the power control information. The power control information includes a carrier power type configured by the base station controller or the base station, a carrier static power level and power fine adjustment, and a channel dynamic power level obtained according to the base station dynamic power control algorithm.

 The carrier slot occupancy state of the multi-carrier transmit channel refers to the occupied state of all slots of the carrier on the multi-carrier transmit channel; if all slots of the carrier are not occupied, the carrier of the multi-carrier transmit channel The slot status is unoccupied; if at least one slot in all slots of the carrier is occupied, the carrier slot status of the multi-carrier transmission channel is occupied. The carrier refers to a carrier where the available idle channel is located.

 103. Allocate the service channel to the access service according to a time slot condition of the multi-carrier transmit channel.

At present, there are two main types of multi-carrier energy-saving technologies: multi-carrier power amplifier shutdown and multi-carrier power amplifier intelligent voltage adjustment. Multi-carrier power amplifier shutdown is based on the occupancy of the time slot on the multi-carrier power amplifier, dynamically turning off the power amplifier of the idle time slot, reducing the power consumption of the power amplifier; the more idle time slots on the multi-carrier transmission channel, the multi-carrier power amplifier off The more energy-saving effect of the break is more significant. The multi-carrier intelligent voltage adjustment is based on the output power of the multi-carrier transmission channel over a period of time, dynamically adjusting the power amplifier bias voltage, improving the working efficiency of the multi-carrier module power amplifier under the same output power; the smoother the output power of the multi-carrier transmission channel is adjusted The more accurate the MCPA bias voltage, the higher the efficiency of the multi-carrier module amplifier. The output power of the multi-carrier transmitting channel and the service occupation of each time slot on the multi-carrier transmitting channel and the power control signal of the service occupied time slot Interest related. According to the service channel allocation method provided in this embodiment, according to the type of the access service, an available idle channel matching the type of the access service is selected to ensure normal access of the service, and at the same time, according to the multi-carrier transmission. The time slot condition of the channel, the traffic channel is allocated to the access service, that is, the traffic channel allocation is from the perspective of energy saving, so that more idle time slots can be obtained on the multi-carrier transmission channel, and the MCPA can be turned off longer. Or, the output power of the multi-carrier transmitting channel is made smoother, so that the bias voltage of the MCPA is more stable, and the power amplifier can be in an efficient working state for a long time, thereby improving the energy-saving effect of the multi-carrier base station.

 As shown in FIG. 2, a method for allocating traffic channels according to an embodiment of the present invention is specifically as follows.

201. Select, according to the type of the access service, an available idle channel that matches the type of the access service.

 The type of the access service and the available idle channel that matches the type of the access service are consistent with the related description in step 101.

 202. Determine whether the multi-carrier transmit channel where the available idle channel is located includes a Broadcast Control Channel (BCCH) carrier, and if there is at least one available idle channel in the available idle channel, the multi-carrier transmit channel includes a BCCH carrier. Then, step 203 is performed; otherwise, step 206 is performed.

 It should be noted that the BCCH carrier always outputs power regardless of whether it carries the service. Therefore, the available idle channel on the multi-carrier transmission channel where the BCCH carrier is located can be preferentially allocated to the access service. When there is no service occupation on the multi-carrier transmission channel where the non-BCCH carrier is located, the MCPA of the multi-carrier transmission channel can be turned off, and a better energy-saving effect is obtained.

 203. Determine whether the carrier where the at least one available idle channel is located includes a BCCH carrier, if the carrier where the at least one available idle channel is located includes a BCCH carrier, perform step 204; if the carrier where the at least one available idle channel is located does not include For the BCCH carrier, go to step 205.

 204. Select an available idle channel on the BCCH carrier as the traffic channel, and allocate the access service to the access service.

It should be noted that when there are two or more available air in the at least one available idle channel The idle channel is on the BCCH carrier, and the traffic channel can be selected and allocated to the access service by one or more service channel selection methods in the prior art. For example, the method for selecting a traffic channel in the prior art may be a range of use of the channel, a quality of the channel, or a random selection.

 For example, if the type of the access service is voice service, step 201 is performed to obtain two available idle channels that match the type of the access service, and the channel types are respectively a Packet Data Channel (PDCH) and a service. The channel (Traffic Channel, TCH), and both are on the BCCH carrier. In this case, a random selection method may be used to select an available idle channel for allocation to the access service, or a quality selection method may be used to select the best quality idle channel. The allocation to the access service may also be selected according to the range of use of the channel, that is, the TCH channel with a small channel usage range is allocated to the access service.

 205. Determine a slot output power of the multi-carrier transmit channel of the at least one available idle channel, and select an available idle channel with a minimum slot output power of the multi-carrier transmit channel as the traffic channel, and allocate the access service to the access service.

 The time slot output power of the multi-carrier transmit channel refers to the sum of the slot output power of each carrier on the multi-carrier transmit channel, which can be obtained by using power control information. The power control information includes a carrier power type configured by the base station controller or the base station, a carrier static power level and power fine adjustment, and a channel dynamic power level obtained according to the base station dynamic power control algorithm.

 206. Determine a slot occupancy status of the multi-carrier transmit channel of the available idle channel. If the slot occupancy status of the multi-carrier transmit channel of the at least one available idle channel is occupied, perform step 207; The time slot occupation status of the multi-carrier transmission channel of the channel is unoccupied, and step 208 is performed.

 207. Select the traffic channel in the at least one available idle channel, and allocate the traffic channel to the access service.

Wherein, when there are two or more of the at least one available idle channel, the traffic channel may be selected and allocated to the access service by one or more service channel selection methods in the prior art. 208. Select the service channel in the available idle channel, and allocate the traffic channel to the access service. The service channel may be selected and allocated to the access service by using one or more service channel selection methods in the prior art. For details, refer to the steps. 204.

 In an implementation scenario, when the carriers of the multi-carrier module are all located on the multi-carrier transmit channel where the BCCH carrier is located, the channel allocation method may only include steps 201-205; in another implementation scenario, the multi-carrier module configuration When multiple carriers are used, and one of the multi-carrier transmit channels includes only the BCCH carrier, the channel allocation method may include only step 201, step 202, and steps 206-208.

 It should be noted that when the number of the service channels to be allocated by the access service is greater than the number of available idle channels obtained by matching the type of the access service obtained on the multi-carrier transmission channel where the BCCH carrier is located, After all available idle channels that match the type of the access service obtained on the multi-carrier transmit channel where the BCCH carrier is located are allocated as the traffic channel to the access service, steps 206-208 are performed, where the non-BCCH carrier is located. A traffic channel is selected on the carrier transmit channel and allocated to the access service.

 In the above embodiment, when the multi-carrier transmit channel in which the available idle channel is located includes a BCCH carrier, the access service is preferentially allocated to the multi-carrier transmit channel on the multi-carrier transmit channel where the BCCH carrier is located. The available idle channel makes the output power of the multi-carrier transmit channel where the BCCH carrier is located more stable, so that the bias voltage of the MCPA is more stable, and the power amplifier can be in an efficient working state for a long time, and the energy saving effect is more significant; when the available idle channel is available When the multi-carrier transmit channel is not included in the BCCH carrier, the time slot occupied by the access service to the multi-carrier transmit channel is occupied as an available idle channel, and the number of idle slots on the multi-carrier transmit channel is increased. The more the multi-carrier power amplifier shutdown function can be fully utilized, the maximum energy saving of the multi-carrier base station can be realized.

It should be noted that when the access service needs to allocate more traffic channels than the available idle channels obtained by the type of the access service obtained on the multi-carrier transmission channel where the BCCH carrier is located, all the BCCH carriers are located. After the available idle channel obtained on the carrier transmit channel that matches the type of the access service is allocated as the traffic channel to the access service, step 306 is performed on the non-BCCH. A service channel selected on the multi-carrier transmission channel where the carrier is located is allocated to the access service.

 In the above embodiment, the access service is preferentially allocated to the available idle channel with the smallest slot output power of the multi-carrier transmit channel, so that the output power of the multi-carrier transmit channel is more stable, thereby making the bias voltage of the MCPA more Smooth, MCPA can be in a state of high efficiency for a long time, improve
