The present invention relates to the field of wireless communications, and in particular, to an apparatus and a method for implementing collaborative work of cells.
A collaboration function refers to that a serving cell performs joint processing on data of the cell and data of a collaboration cell. Currently, a method for implementing collaborative work of cells is provided, including: an operator determines a serving cell according to requirements of a preset collaboration function on a transmission delay and a transmission bandwidth that are of the serving cell, and determines a collaboration cell according to requirements of the preset collaboration function on a transmission delay and a transmission bandwidth that are of the collaboration cell, so that the serving cell may perform joint processing on data of the serving cell and data of the collaboration cell by using the collaboration function.

Referring to
Step 301: A collaboration function apparatus acquires a transmission delay and a transmission bandwidth that are of a serving cell and a transmission delay and a transmission bandwidth that are of at least one collaboration cell.
The collaboration function apparatus refers to an apparatus with a collaboration function;
and the collaboration function refers to that a cell performs joint processing on data of multiple cells, where a cell that performs the joint processing on data is referred to as a serving cell, the collaboration function apparatus is generally deployed in the serving cell, and a cell whose data is jointly processed is referred to as a collaboration cell.

The preset condition may include that a data processing capability of the serving cell exceeds a threshold, and the like.
A method used by the collaboration function apparatus to acquire the transmission delay and the transmission bandwidth in step 301 is any one of existing methods for acquiring a transmission delay and a transmission bandwidth. In this embodiment of the present invention, the method used by the collaboration function apparatus to acquire the transmission delay and the transmission bandwidth is not described in detail. For example, the base station stores the transmission delay and the transmission bandwidth that are of the serving cell and the transmission delay and the transmission bandwidth that are of the at least one collaboration cell; the collaboration function apparatus sends an acquisition request to the base station, where the acquisition request carries an identifier of the serving cell and an identifier of the at least one collaboration cell; the base station acquires the transmission delay and the transmission bandwidth that are of the serving cell according to the identifier of the serving cell, and sends the transmission delay and the transmission bandwidth that are of the serving cell to the collaboration function apparatus; the base station acquires the transmission delay and the transmission bandwidth that are of the at least one collaboration cell according to the identifier of the at least one collaboration cell, and sends the transmission delay and the transmission bandwidth that are of the at least one collaboration cell to the collaboration function apparatus.
Step 302: The collaboration function apparatus acquires a transmission type of the serving cell according to the transmission delay and the transmission bandwidth that are of the serving cell.
Step 302 may include the following steps (1) and (2):
(1) The collaboration function apparatus determines a transmission delay range and a transmission bandwidth range that are of the serving cell according to the transmission delay and the transmission bandwidth that are of the serving cell.

The transmission delay range that the transmission delay of the serving cell belongs to may be determined according to the transmission delay and the transmission delay range that are of the serving cell, and the transmission bandwidth range that the transmission bandwidth of the serving cell belongs to may be determined according to the transmission bandwidth and the transmission bandwidth range that are of the serving cell.
For example, a transmission delay range of transmission delay range 1 is 0 to 10 us, a transmission delay range of transmission delay range 2 is 10 us to 130 us, a transmission delay range of transmission delay range 3 is greater than 130 us, a transmission bandwidth range of transmission bandwidth range 1 is greater than 30 G, a transmission bandwidth range of transmission bandwidth range 2 is 10 G to 30 G, a transmission bandwidth range of transmission bandwidth range 3 is less than 10 G, the transmission delay of the serving cell is 8 us, and the transmission bandwidth of the serving cell is 40 G. The transmission delay of the serving cell is in transmission delay range 1, and the transmission bandwidth of the serving cell is in transmission bandwidth range 1, and therefore, the collaboration function apparatus may determine that the transmission delay range of the serving cell is transmission delay range 1, and the transmission bandwidth range of the serving cell is transmission bandwidth range 1.
(2) The collaboration function apparatus acquires the transmission type of the serving cell from a correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type according to the transmission delay range and the transmission bandwidth range that are of the serving cell.
Specifically, the correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type is stored in advance in the collaboration function apparatus, and the transmission type corresponding to the transmission delay range and the transmission bandwidth range that are of the serving cell is acquired from the correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type according to the transmission delay range and the transmission bandwidth range that are of the serving cell.
The collaboration function apparatus may store the correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type in a form of a table, for example, as shown in Table 1.
Because the transmission delay of the serving cell is within 0 to 10 us, and the transmission bandwidth of the serving cell is greater than 30 G, the collaboration function apparatus acquires, according to the transmission delay range of the serving cell: 0 to 10 us and the transmission bandwidth range of the serving cell: greater than 30 G, the transmission type, being transmission type 1, of the serving cell from the correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type.
Step 303: The collaboration function apparatus separately acquires a transmission type of each collaboration cell according to the transmission delay and the transmission bandwidth that are of each collaboration cell.
Step 303 may include the following steps (1) and (2):
(1) The collaboration function apparatus separately determines a transmission delay range and a transmission bandwidth range that are of each collaboration cell according to the transmission delay and the transmission bandwidth that are of each collaboration cell.
The transmission delay range and the transmission bandwidth range are stored in advance in the collaboration function apparatus. The transmission delay range that the transmission delay of each collaboration cell belongs to may be separately determined according to the transmission delay and the transmission delay range that are of each collaboration cell; and the transmission bandwidth range of each collaboration cell may be separately determined according to the transmission bandwidth and the transmission bandwidth range that are of each collaboration cell.
(2) The collaboration function apparatus separately acquires the transmission type of each collaboration cell from a correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type according to the transmission delay range and the transmission bandwidth range that are of each collaboration cell.
Specifically, the correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type is stored in advance in the collaboration function apparatus, and the transmission type corresponding to the transmission delay range and the transmission bandwidth range that are of each collaboration cell is separately acquired from the correspondence among the transmission delay range, the transmission bandwidth range, and the transmission type according to the transmission delay range and the transmission bandwidth range that are of each collaboration cell.
For example, a transmission delay of a collaboration cell is 5 us, and a transmission bandwidth of the collaboration cell is 50 G. The transmission delay of the collaboration cell is within transmission delay range 1, and the transmission bandwidth of the collaboration cell is within transmission bandwidth range 1, and therefore, the collaboration function apparatus may determine, according to Table 1, that a transmission delay range of the collaboration cell is transmission delay range 1, and a transmission bandwidth range of the collaboration cell is transmission bandwidth range 1.
Step 304: The collaboration function apparatus separately acquires a transmission scenario of each collaboration cell according to the transmission type of the serving cell and the transmission type of each collaboration cell.
Specifically, a correspondence among the transmission type of the serving cell, the transmission type of the collaboration cell, and the transmission scenario is stored in advance in the collaboration function apparatus. The transmission scenario of each collaboration cell is separately acquired from the correspondence among the transmission type of the serving cell, the transmission type of the collaboration cell, and the transmission scenario according to the transmission type of the serving cell and the transmission type of each collaboration cell.
The transmission scenario is defined according to a transmission condition difference between the serving cell and the collaboration cell. A transmission condition between the serving cell and the collaboration cell may determine the transmission delay and the transmission bandwidth that are of the serving cell and the transmission delay and the transmission bandwidth that are of the collaboration cell, and therefore, the transmission scenario is essentially determined according to the transmission delay and the transmission bandwidth that are of the serving cell and the transmission delay and the transmission bandwidth that are of the collaboration cell. The transmission scenario of each collaboration cell in this embodiment of the present invention is the transmission scenario between each collaboration cell and the serving cell, and the collaboration function apparatus may store the correspondence among the transmission type of the serving cell, the transmission type of the collaboration cell, and the transmission scenario in a form of a table, for example, as shown in Table 2.
For example, the transmission type of the serving cell is transmission type 1, and the transmission type of the collaboration cell is transmission type 1, and therefore, the collaboration function apparatus acquires, according to transmission type 1 of the serving cell and transmission type 1 of the collaboration cell, the transmission scenario, being transmission scenario 1, between the collaboration cell and the serving cell from the correspondence among the transmission type of the serving cell, the transmission type of the collaboration cell, and the transmission scenario of the collaboration cell.
Step 305: The collaboration function apparatus calls a collaboration function according to the transmission scenario of each collaboration cell, and implements collaborative work of cells by using the collaboration function.
Each collaboration function is corresponding to a first transmission delay range and a first transmission bandwidth range, and a second transmission delay range and a second transmission bandwidth range, where the first transmission delay range and the first transmission bandwidth are requirements of the collaboration function on the transmission delay and the transmission bandwidth that are of the serving cell, and the second transmission delay range and the second transmission bandwidth range are requirements of the collaboration function on the transmission delay and the transmission bandwidth that are of the collaboration cell; according to the first transmission delay range, the first transmission bandwidth range, the second transmission delay range and the second transmission bandwidth range, at least one transmission scenario that is between the serving cell and the collaboration cell and that the collaboration function is applicable to, that is, at least one transmission scenario of the collaboration cell, may be determined, and a correspondence between the collaboration function and the at least one transmission scenario of the collaboration cell is stored.
Step 305 may be implemented by using the following first manner, second manner or third manner. The first manner includes the following steps (1) to (4):
(1) The collaboration function apparatus selects a collaboration cell having a same transmission scenario from each collaboration cell.
Specifically, the collaboration function apparatus selects the collaboration cell having the same transmission scenario from each collaboration cell according to the transmission scenario of each collaboration cell.
The quantity of collaboration cells may be set and modified according to needs of the collaboration function. For example, when the collaboration function supports two collaboration cells, two collaboration cells having a same transmission scenario are selected from each collaboration cell, and if there are no two collaboration cells having a same transmission scenario in each collaboration cell, one collaboration cell may be selected from each collaboration cell.
For example, collaboration cells that may perform collaboration with the serving cell are collaboration cell 1, collaboration cell 2, collaboration cell 3, collaboration cell 4, collaboration cell 5 and collaboration cell 6, a transmission scenario of collaboration cell 1 and a transmission scenario of collaboration cell 6 are transmission scenario 1, a transmission scenario of collaboration cell 2 and a transmission scenario of collaboration cell 4 are transmission scenario 2, and a transmission scenario of collaboration cell 3 and a transmission scenario of collaboration cell 5 are transmission scenario 3. Collaboration cells having a same transmission scenario are selected to perform collaboration. That the quantity of collaboration cells performing collaborative work is two is used as an example for description, and collaboration cells having a same transmission scenario are selected to perform collaboration, that is, collaboration cell 1 and collaboration cell 6 are selected to perform collaboration, or collaboration cell 2 and collaboration cell 4 are selected to perform collaboration, or collaboration cell 3 and collaboration cell 5 are selected to perform collaboration.
(2) Form a first cell connection set by using the serving cell and the selected collaboration cell, and form a first transmission scenario set by using the transmission scenario of the selected collaboration cell.
A transmission scenario set includes at least one transmission scenario, and in this step, the first transmission scenario set includes one transmission scenario.
The foregoing collaboration cell 1 to collaboration cell 6 are still used as an example. For example, the first cell connection set includes the serving cell, collaboration cell 1 and collaboration cell 6, and the first transmission scenario set includes transmission scenario 1; or the first cell connection set includes the serving cell, collaboration cell 2 and collaboration cell 4, and the first transmission scenario set includes transmission scenario 2; or the first cell connection set includes collaboration cell 3 and collaboration cell 5, and the first transmission scenario set includes transmission scenario 3.
(3) The collaboration function apparatus calls a corresponding collaboration function according to the first transmission scenario set.
Specifically, a correspondence between the transmission scenario set and the collaboration function is stored in advance in the collaboration function apparatus, and the collaboration function corresponding to the first transmission scenario set is acquired from the correspondence between the transmission scenario set and the collaboration function according to the first transmission scenario set.
The collaboration function apparatus may store the correspondence between the transmission scenario set and the collaboration function in a form of a table, for example, as shown in Table 3.
For example, the first transmission scenario set is transmission scenario set 1, which includes transmission scenario 1, and a collaboration function corresponding to transmission scenario set 1 is collaboration function 1. The collaboration function apparatus acquires, according to transmission scenario set 1, collaboration function 1 corresponding to transmission scenario set 1 from the correspondence between the transmission scenario set and the collaboration function.
It should be noted that, in this embodiment of the present invention, the transmission scenario between the serving cell and the collaboration cell may be determined according to the transmission delay and the transmission bandwidth that are of the serving cell and the transmission delay and the transmission bandwidth that are of the collaboration cell, and then the collaboration function is called according to the transmission scenario between the serving cell and the collaboration cell.
(4) The collaboration function apparatus performs collaborative work on the cells in the first cell connection set by using the collaboration function.
Specifically, the collaboration cell in the first cell connection set sends data to the serving cell in the first cell connection set, and the serving cell in the first cell connection set receives the data sent by the collaboration cell in the first cell connection set and performs collaboration processing on the received data.
For example, the serving cell performs collaborative work on the cells in cell connection set 1 by using collaboration function 1, that is, collaboration cell 1 and collaboration cell 6 send data to the serving cell, and the serving cell receives the data sent by collaboration cell 1 and collaboration cell 6 and processes the received data in a collaboration manner specified by collaboration function 1.
The second manner includes the following steps (A) to (D):
(A) The collaboration function apparatus selects a first preset quantity of collaboration cells having highest priorities from each collaboration cell.
Specifically, a priority of each collaboration cell is stored in advance in the collaboration function apparatus, and the first preset quantity of collaboration cells having highest priorities are selected from each collaboration cell according to the priority of each collaboration cell.
The first preset quantity may be set and modified according to needs of the collaboration function. In this embodiment of the present invention, the first preset quantity is not specifically limited. For example, the first preset quantity is one, two or the like.
For example, collaboration cells that are applicable to performing collaboration with the serving cell and that are listed in descending order of priorities are: collaboration cell 1, collaboration cell 2, collaboration cell 3, collaboration cell 4, collaboration cell 5 and collaboration cell 6, a transmission scenario of collaboration cell 1 and a transmission scenario of collaboration cell 6 are transmission scenario 1, a transmission scenario of collaboration cell 2 and a transmission scenario of collaboration cell 4 are transmission scenario 2, and a transmission scenario of collaboration cell 3 and a transmission scenario of collaboration cell 5 are transmission scenario 3. That the first preset quantity is two is used as an example for description, and two collaboration cells having highest priorities, collaboration cell 1 and collaboration cell 2, are selected to perform collaboration.
(B) The collaboration function apparatus forms a second cell connection set by using the serving cell and the selected first preset quantity of collaboration cells, and forms a second transmission scenario set by using the transmission scenario of the selected first preset quantity of collaboration cells.
In this step, the second transmission scenario set includes at least one transmission scenario.
For example, the second cell connection set includes the serving cell, collaboration cell 1 and collaboration cell 2; and the second transmission scenario set includes transmission scenario 1 and transmission scenario 2.
(C) The collaboration function apparatus calls a corresponding collaboration function according to the second transmission scenario set.
Specifically, a correspondence between the transmission scenario set and the collaboration function is stored in advance in the collaboration function apparatus, and the collaboration function corresponding to the second transmission scenario set is acquired from the correspondence between the transmission scenario set and the collaboration function according to the second transmission scenario set.
For example, the second transmission scenario set is transmission scenario set 2, which includes transmission scenario 1 and transmission scenario 2, and collaboration function 2 corresponding to transmission scenario set 2 is acquired from the correspondence between the transmission scenario set and the collaboration function according to transmission scenario set 2.
(D) The collaboration function apparatus performs collaborative work on the cells in the second cell connection set by using the collaboration function.
Specifically, the collaboration cell in the second cell connection set sends data to the serving cell in the second cell connection set, and the serving cell in the second cell connection set receives the data sent by the collaboration cell in the second cell connection set and performs collaboration processing on the received data.
For example, the second cell connection set is cell connection set 2, and the serving cell performs collaborative work on the cells in cell connection set 2 by using collaboration function 2, that is, collaboration cell 1 and collaboration cell 2 send data to the serving cell, and the serving cell receives the data sent by collaboration cell 1 and collaboration cell 2 and processes the received data in a collaboration manner specified by collaboration function 2.
The third manner includes the following steps (a) to (e):
(a) The collaboration function apparatus selects a collaboration cell having a highest priority from each collaboration cell.
Specifically, a priority of each collaboration cell is stored in advance in the collaboration function apparatus, and the collaboration cell having the highest priority is selected from each collaboration cell according to the priority of each collaboration cell.
(b) The collaboration function apparatus selects a second preset quantity of collaboration cells having highest priorities from a collaboration cell having a same transmission scenario as the collaboration cell having the highest priority.
Specifically, the collaboration function apparatus acquires, according to the transmission scenario of the collaboration cell having the highest priority, the collaboration cell having the same transmission scenario as the collaboration cell having the highest priority, and selects the second preset quantity of collaboration cells having highest priorities from the acquired collaboration cell.
The second preset quantity may be set and modified according to needs of the collaboration function. In this embodiment of the present invention, the second preset quantity is not specifically limited. For example, the second preset quantity is one, two or the like.
For example, collaboration cells that may perform collaboration with the serving cell and that are listed in descending order of priorities are: collaboration cell 1, collaboration cell 2, collaboration cell 3, collaboration cell 4, collaboration cell 5 and collaboration cell 6, a transmission scenario of collaboration cell 1 and a transmission scenario of collaboration cell 6 are transmission scenario 1, a transmission scenario of collaboration cell 2 and a transmission scenario of collaboration cell 4 are transmission scenario 2, and a transmission scenario of collaboration cell 3 and a transmission scenario of collaboration cell 5 are transmission scenario 3. That the collaboration function supports two collaboration cells is used as an example for description, and the second preset quantity is one, a collaboration cell having a highest priority, that is, collaboration cell 1, is selected, and one collaboration cell having a highest priority is selected from a collaboration cell having a same transmission scenario as collaboration cell 1 to perform collaboration, that is, collaboration cell 6 may be selected to perform collaboration.
(c) The collaboration function apparatus forms a third cell connection set by using the serving cell, the collaboration cell having the highest priority and the selected second preset quantity of collaboration cells, and forms a third transmission scenario set by using the transmission scenario of the collaboration cell having the highest priority.
In this step, the third transmission scenario set includes one transmission scenario.
For example, the third cell connection set includes the serving cell, collaboration cell 1 and collaboration cell 6; the third transmission scenario set includes transmission scenario 1.
(d) The collaboration function apparatus calls a corresponding collaboration function according to the third transmission scenario set.
Specifically, a correspondence between the transmission scenario set and the collaboration function is stored in advance in the collaboration function apparatus, and the collaboration function corresponding to the third transmission scenario set is acquired from the correspondence between the transmission scenario set and the collaboration function according to the third transmission scenario set.
For example, the third transmission scenario is transmission scenario 1, and collaboration function 1 corresponding to transmission scenario set 1 is acquired from the correspondence between the transmission scenario set and the collaboration function according to transmission scenario set 1.
(e) The collaboration function apparatus performs collaborative work on the cells in the third cell connection set by using the collaboration function.
Specifically, the collaboration cell in the third cell connection set sends data to the serving cell in the third cell connection set, and the serving cell in the third cell connection set receives the data sent by the collaboration cell in the third cell connection set and performs collaboration processing on the received data.
For example, the third cell connection set is cell connection set 3, and the serving cell performs collaborative work on the cells in cell connection set 3 by using collaboration function 1, that is, collaboration cell 1 and collaboration cell 6 send data to the serving cell, and the serving cell receives the data sent by collaboration cell 1 and collaboration cell 6 and processes the received data in a collaboration manner specified by collaboration function 1.
It should be noted that, in this embodiment of the present invention, the foregoing step 301 to step 305 are performed every a preset time. The preset time may be set and modified according to needs.
