The so-called co-cell refers to a plurality of stations or radio frequency modules for transmitting and receiving signals in a cell. These stations or radio modules are distributed at different locations and have the same cell identity (ID). This networking mode can utilize the underlying network on the micro-area to absorb traffic in the traffic hotspot area, and enhance network coverage of the blind area, thereby improving the communication quality and network capacity of the entire network.

When the user accesses a location group in the cell, other location groups or macro networks in the cell will reserve corresponding resources for the user to ensure smooth switching when the user moves between the macro base station 101 and the micro base station 102. To avoid affecting the user's business experience.

 As shown in FIG. 2, Embodiment 1 of the present invention provides a channel configuration method, which is applied to a cell based on a macro-initial network structure, and includes:

 201. The micro base station acquires first channel configuration information that is sent by the network side device, where the first channel configuration information is used to configure a service channel of the micro base station on the BCCH carrier of the broadcast control channel, and the service channel of the micro base station on the BCCH carrier The cell is separated from the traffic channel on the BCCH carrier by the macro base station of the cell.

 The micro base station may be a micro base station located in a location group of the traffic hotspot area in the cell, or may be a micro base station located in a weak coverage area location group in the cell.

 202. The micro base station configures a service channel on a BCCH carrier according to the first channel configuration information.

 In this embodiment, the traffic channel configured by the micro base station on the BCCH carrier is separated from the traffic channel of the macro base station on the BCCH carrier, such that the micro base station and the macro base station are not on the BCCH carrier. The service channel reserves resources for the accessed users. The service channel resources of the micro base station on the BCCH carrier are fully translated and can be fully applied to the service data transmission on the macro network, thereby improving the service capacity of the cell.

 In this embodiment, the base station may be located in a location group of the traffic hotspot area in the cell, and the service capacity of the location group where the micro base station is located is increased.

 In this embodiment, if the service capacity of the location group of the micro base station is further increased, the first channel configuration information may be used to configure all channels of the base station on the BCCH carrier as the traffic channel, so that the micro The number of traffic channels configured by the base station according to the first channel configuration information is further increased.

 In this embodiment, before performing step 201, in order to separate the traffic channel of the micro base station on the BCCH carrier from the traffic channel of the macro base station of the cell on the BCCH carrier, the channel configuration method may also be Including the following implementation steps:

The network side device acquires the amount of users carried by the micro base station. In general, the network side device can collect the amount of users carried by the micro base station in real time. After the network side device acquires the user quantity carried by the micro base station, the network side device determines whether the user quantity carried by the micro base station is equal to or greater than a first predetermined user quantity threshold, and determines that the micro base station is in the BCCH. Whether the traffic channel configured on the carrier is co-cell with the traffic channel of the macro base station of the cell on the BCCH carrier, and if the result of the determination is that the amount of users carried by the micro base station is equal to or greater than a first predetermined user amount threshold, and the micro Transmitting, by the base station, the traffic channel configured on the BCCH carrier and the traffic channel of the macro base station of the cell in the BCCH carrier, the first first channel configuration information, the first first channel, to the micro base station The configuration information is further used to separate the traffic channel of the base station on the BCCH carrier from the traffic channel of the macro base station of the cell on the BCCH carrier; the micro base station acquires the After a first channel configuration information, according to the first first channel configuration information, the traffic channel of the activated base station on the BCCH carrier and the macro base of the cell Traffic channels on the BCCH carrier cells were isolated.

 In the above step, when the number of users carried by the micro base station is equal to or greater than the first predetermined user quantity threshold, the situation indicates that the micro base station can be used to carry resources of the user, and the service channel resources are urgently needed to meet the user requirements. . In order to solve the problem of the resource channel shortage of the micro base station, it is necessary to separate the traffic channel of the micro base station on the BCCH carrier from the service channel common cell of the macro base station of the cell on the BCCH carrier. After the traffic channel of the micro base station on the BCCH carrier is separated from the traffic channel of the macro base station of the cell on the BCCH carrier, the micro base station and the macro base station are not on the service channel of the BCCH carrier. The accessed user reserves resources, and the reserved traffic channel resources originally reserved on the BCCH carrier of the micro base station are fully translated, and can be fully applied to service data transmission on the macro network, thereby improving the service capacity of the cell.

 In this embodiment, the first channel configuration information may be used to configure a control channel of the base station on the BCCH carrier, in order to ensure that the control channel covers the location group of the micro base station. The base station may further configure a control channel on the BCCH carrier according to the first channel configuration information. Specifically, the micro base station may simultaneously configure a control channel and a traffic channel on the BCCH carrier according to the first channel configuration information, configure a partial time slot on a part of the BCCH wave as a control channel, and configure a partial time slot into a service. channel. For example, if the BCCH wave contains 8 time slots, the first three time slots can be configured as a control channel, and the last five time slots can be configured as a traffic channel.

In this embodiment, the micro base station may also be located in a weak coverage area location group in the cell, where the first channel configuration information is further used to configure the second base station to control on a BCCH carrier. Channel: The micro base station may further configure a control channel on the BCCH carrier according to the first channel configuration information. Specifically, the base station may simultaneously configure a control channel and a traffic channel on the BCCH carrier according to the first channel configuration information, configure a partial time slot on a part of the BCCH wave as a control channel, and configure a partial time slot as a traffic channel. . Since the control channel transmitted by the macro base station may not adequately cover the weak coverage area, the control channel configured by the micro base station can ensure that the user terminal on the weak coverage area location group can receive a good control signal.

 In this embodiment, the first channel configuration information may also be used to use the RFU common cell in the macro network in the traffic channel of the base station on the BCCH carrier, and the macro base station uses the RFU to transmit and receive signals. Or the first channel configuration information is further used to use the RRU common cell in the macro network in the service channel of the base station on the BCCH carrier, and the macro base station uses the RRU to send and receive signals. If a plurality of the micro base stations are located in the cell, the user terminal accessing the traffic channel of the micro base station on the BCCH carrier can smoothly switch to the service channel of the other micro base station on the BCCH carrier.

 In the embodiment, the service channel of the micro base station on the TCH wave and the service channel of the macro base station on the TCH wave may be shared by the cell, so that the user can smoothly switch between the location group where the micro base station is located and the macro network. .

The micro base stations on the location group 2 and the location group 4 configure a channel on the BCCH carrier, and the channel configured on the BCCH carrier includes a control channel and a traffic channel, and a traffic channel is configured on the TCH carrier. The base station on the location group 3 configures a channel on the BCCH carrier, and the channels configured on the BCCH carrier are all control channels, and the traffic channel is configured on the TCH carrier. The base station on the location group 5 configures the channel on the BCCH carrier, and the channels configured on the BCCH carrier are all traffic channels, and the traffic channel is configured on the TCH carrier.

When the macro base station or the micro base station configures a channel on the BCCH carrier, as shown in FIG. 4, the first time slot to the third time slot of the BCCH carrier can be configured as BCCH, SDCCH, and SDCCH, respectively, and the BCCH carrier is used. The 4th time slot to the 8th time slot are respectively configured as TCH, TCH, PDCH, PDCH and PDCH. The traffic channel configured on the BCCH carrier of the micro base station on the location group 2 and the location group 4 is separated from the traffic channel of the macro base station of the cell on the BCCH carrier, so that the micro base station on the location group 2 and the location group 4 The macro base stations do not reserve resources for the accessed users on the traffic channels on the BCCH carrier. When there is a user accessing the traffic channel of the macro base station on the BCCH carrier, the base station on the location group 2 and the location group 4 does not need to reserve the corresponding traffic channel on the BCCH carrier, and these corresponding services on the BCCH carrier The channel can be used to access users on location group 2 and location group 4, thereby increasing the traffic capacity of location group 2 and location group 4. The channel configured on the BCCH carrier by the micro base station at position 5 is all a traffic channel, and is co-cell separated from the traffic channel of the macro base station of the cell on the BCCH carrier, so that the micro base station and the macro base station on the location group 5 All the channels on the BCCH carrier of the micro base station on the BCCH carrier can be used to access the users on the location group 5, thereby greatly improving the location group. 5 business capacity.

If the result of the determination is that the amount of users carried by the micro base station is equal to or greater than a first predetermined user quantity threshold, and the traffic channel configured by the micro base station on the BCCH carrier is the same as the macro base station of the cell.

The traffic channel common cell on the BCCH carrier transmits the first channel configuration information to the base station. The first channel configuration information is used to separate a traffic channel of the micro base station on a BCCH carrier from a traffic channel common cell of a macro base station of the cell on a BCCH carrier.

Since the control channel transmitted by the macro base station can well cover the location group of the traffic hotspot area in the cell, even if the micro base station no longer transmits the control channel, the user on the location group will not be bad. influences. Therefore, the micro base station may configure, according to the first channel configuration information, all channels of the micro base station on the BCCH carrier as a traffic channel, and the configured traffic channels and the macro base station of the cell are on the BCCH carrier. The traffic channels are separated from each other, so that the service channel capable of providing user access on the location group of the micro base station is greatly increased, and the service capacity of the location group of the micro base station is improved.
