Description

A small cell sleep control method and network equipment

technical field

The present invention relates to the communication field, in particular to a small cell sleep control method and network equipment.

Background technique

In recent years, resource crisis, especially energy shortage, has attracted people's attention. Studies have shown that wireless communication is one of the major energy-consuming industries. At present, cellular networks are the main wireless communication networks. In cellular networks, cellular base stations need to adopt Larger transmit power to transmit signals to ensure coverage of a wide range of service cells. User equipment needs to use relatively large transmit power to transmit signals so that the transmitted signals can still meet a certain communication quality when reaching the base station. Therefore, wireless communication networks Especially the cellular network consumes a lot of energy in daily life.

The macro cell uses the macro base station to provide network services for the user equipment. The macro cell has the characteristics of large coverage and high transmission power. Small cells use micro base stations to provide network services for user equipment. Compared with macro cells, small cells have smaller coverage and lower transmission power. Small cells use smaller transmission power to transmit signals to ensure a small range. , a small number of user equipments obtain network services, therefore, using a small cell to provide network services for a small range of user equipment consumes less energy. However, in order to make the small cell more green and energy-saving, people have proposed a more advanced technology-sleep technology. Sleep technology means that when the device is not in service, most or even all hardware and software modules are turned off, and only a small amount of necessary activities are performed. of a technique. When the small cell is not performing network services, it is placed in a sleep state, and when it is required to provide network services, the small cell is controlled to enter a wake-up state to provide network services for user equipment that needs services.

There are mainly two methods for small cell sleep control in the prior art. One method is that the base station sends downlink paging to the user equipment or the user equipment sends an uplink connection request to the base station to establish a connection, and then MME (Mobile Management Entity, mobility management The entity) first detects the small cells around the user equipment that can provide services for the user equipment, and then sends service request messages to these small cells, and the small cells that receive the service request messages enter the wake-up state to provide services for the user equipment. Another method is that the user equipment broadcasts a service request message to the small cell, and the small cell that receives the service request message enters an awake state to provide service for the user equipment. However, in the above two control methods, any small cell that receives the service request message will enter the wake-up state to provide services for the user equipment, and it is inevitable that multiple small cells will be woken up, so the energy consumption is relatively large.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

An embodiment of the present invention provides a sleep control method for a small cell, which is applied to a network device, as shown in FIG. 1 , including:

101. Receive a service request message sent by a user equipment, where the service request message includes a user equipment identifier and a service priority, where the service priority is a service priority required by the user equipment for current communication.

It should be noted that the network device provided by the embodiment of the present invention may specifically be a micro base station or MME to which the small cell belongs. When the network device is a micro base station, the micro base station receives the service request message sent by the user equipment, or the macro base station first The service request message sent by the user equipment is received, and then the macro base station sends the service request message to the micro base station to which the small cell belongs, and finally the micro base station receives the service request message sent by the user equipment. When the network device is an MME, the MME receives the service request message sent by the user equipment.

102. Store the user equipment identifier and the service priority in a service list of serving small cells, where the serving small cells are small cells that can satisfy the service request of the user equipment.

After the network device receives the service request message sent by the user equipment, it stores the user equipment information contained in the received service request message in the service list of the serving small cell, the user equipment information including the user equipment identifier and service priority, The service priority is the service priority required by the user equipment for current communication.

It should be noted that the serving small cell is a small cell that can provide a service for the user equipment, or a small cell that is relatively close to the user equipment and whose signal quality can meet the service request of the user equipment.

103. Determine whether the serving small cell corresponding to the service list satisfies a wake-up condition.

104. When the serving small cell corresponding to the service list satisfies the wake-up condition, control the serving small cell to enter the wake-up state.

In this way, when there is a serving small cell meeting the wake-up condition in the service list, the network device controls the serving small cell to enter the wake-up state, which can prevent the network device from waking up multiple small cells and reduce energy consumption.

An embodiment of the present invention provides a sleep control method for a small cell, as shown in FIG. 2 , including:

201. The user equipment sends a service request message to a network device.

The user equipment may send a service request message in a broadcast manner, where the service request message includes a user equipment identifier and a service priority, and the user equipment identifier is used to identify different user equipments. Exemplarily, the user equipment identity may be an IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity). The service priority is the service priority required by the user equipment for current communication. According to the service type of the communication, the communication service required by the user equipment may be prioritized. For example, the communication service may be prioritized according to the type of voice, data service, value-added service, etc., and the priority of the voice service may be set to 1. , set the priority of the data service as 2, set the priority of the value-added service as 3, and so on.

It should be noted that there is a one-to-one correspondence between the user equipment identifier and the service priority in the service request message.

202. The network device receives a service request message sent by the user equipment, where the service request message includes a user equipment identifier and a service priority, where the service priority is a service priority required by the user equipment for current communication.

203. The network device stores the user equipment identifier and the service priority in a service list of serving small cells, where the serving small cells are small cells that can satisfy the service request of the user equipment.

Step 203 specifically includes: when the network device is the micro base station, the micro base station receives the service request message broadcast by the user equipment, and stores the user equipment identifier and service priority carried in the service request message to the service list of the serving small cell managed by the micro base station; or the micro base station receives the service request message forwarded by the macro base station, where the service request message is a message sent by the user equipment to the macro base station, And store the user equipment identifier and service priority in the service request message into the service list of the serving small cell managed by the micro base station. It should be noted that the serving small cell is one or more small cells managed by the micro base station.

When the network device is the MME, the MME receives the service request message sent by the user equipment, and searches for a serving small cell for the user equipment among the multiple small cells it manages, and then sends the service request message in the service request message The user equipment identifier and service priority of the user equipment are stored in the service list of the serving small cell. It should be noted that the serving small cell is a small cell that can provide services for the user equipment among the small cells managed by the MME, the signal quality of the small cell can meet the service request of the user equipment, and the number of the serving small cells Can be multiple. In practical application, the MME may select the serving small cell according to whether the channel condition of the small cell meets the requirement or according to factors such as whether the service provided by the small cell is an open service or a closed service. After the MME selects one or more small cells that can provide services for the user equipment, the MME stores the user equipment information in the service list of these small cells.

204. The network device judges whether the serving small cell corresponding to the service list satisfies the wake-up condition.

There are three methods for the network device to determine whether the serving small cell corresponding to the service list meets the wake-up condition: first, the network device determines whether there is a service with a service priority greater than or equal to a preset service priority in the service list Priority, the preset service priority is preset by the network device for the small cell it manages, and is used to indicate the priority of the service request processed by the small cell managed by the network device; the second type, the network The device judges whether the number of user equipment identifiers in the service list is greater than or equal to a preset threshold; thirdly, the network device judges whether there is a service priority in the service list with a service priority greater than or equal to a preset service priority, And judging whether the number of user equipment identifiers in the service list is greater than or equal to a preset threshold.

It should be noted that, each time the network device stores service request information of a user equipment in the service list of the serving small cell, it needs to judge whether the serving small cell corresponding to the service list satisfies the wake-up condition. Whether the small cell meets the wake-up condition includes: comparing the service priority in the service request message with the preset service priority, and judging whether the service priority of the user equipment is greater than or equal to the preset service priority according to the comparison result; Or compare the number of user equipment identifiers in the service list with the preset threshold, and judge whether the service priority of the user equipment is greater than or equal to the preset service priority according to the comparison result; or the service request The service priority in the message is compared with the preset service priority, and at the same time, the number of user equipment identifiers in the service list is compared with the preset threshold, and the service priority of the user equipment is determined according to the comparison result whether it is greater than or equal to the preset service priority and simultaneously determine whether the service priority of the user equipment is greater than or equal to the preset service priority.

205. When the serving small cell corresponding to the service list satisfies the wake-up condition, control the serving small cell to enter the wake-up state.

Step 205 specifically includes: when there is a service priority greater than or equal to a preset service priority in the service list, or when the number of user equipment identifiers in the service list is greater than or equal to a preset threshold, or in the service list When there is a service priority with a service priority greater than or equal to a preset service priority and the number of user equipment identities in the service list is greater than or equal to a preset threshold, the MME sends a service request to the serving small cell message, so that the serving small cell enters the wake-up state according to the service request message.

For example, when the network device is a micro base station, as shown in FIG. 3 , FIG. 3 is a control method for user equipment 1 to wake up a small cell a. The user equipment 1 indicates that the identity of the user equipment is 1, and the micro base station A manages The small cell a, it should be noted that the micro base station A may also manage other small cells except the small cell a. The method includes:

301. User equipment 1 sends a service request message to Femtocell A.

Specifically, the user equipment 1 may send a service request message in the form of broadcast, the service request message includes the identification 1 of the user equipment 1 and the service priority 5, and the service priority 5 indicates that the user equipment 1 needs The service priority is 5.

The micro base stations in the network that are closer to the user equipment 1 will receive the service request message broadcast by the user equipment 1, or the macro base stations in the network that are closer to the user equipment 1 can also receive the service request message, and receive the service request message. The macro base station of the service request message sends the service request message to the micro base station near the user equipment 1, and the micro base station near the user equipment 1 receives the service request message.

Assuming that the micro base station A is a micro base station close to the user equipment 1, and the small cell a is a small cell managed by the micro base station A, the small cell a may be used as the serving small cell. The embodiment of the present invention illustrates a method for waking up the small cell a after the micro base station A receives the service request message sent by the user equipment 1 .

302. The micro base station A receives the service request message of the user equipment 1, and stores the user equipment identifier and the service priority in the service request message into the service list of the serving small cell a.

Assume that the micro base station A is a base station closer to the user equipment 1, the micro base station A manages the small cell a, and the micro base station A receives the service request message. It can be known from step 301 that the user equipment identifier included in the service request message is 1, and the priority of the service required by the user equipment 1 for current communication is 5. The micro base station A stores the received user equipment information in the service list of the small cell a. Assume that up to the current moment, the service list of the small cell a has stored information of 5 user equipments in total.

303. The micro base station A judges whether the small cell a satisfies the wake-up condition.

The micro base station A can judge whether the small cell a satisfies the wake-up condition according to the three methods described in step 204, specifically, including: first, the micro base station A judges whether the service list of the small cell a is There is a service priority greater than or equal to the preset service priority; second, the micro base station A judges whether the number of user equipment identities in the service list of the small cell a is greater than or equal to a preset threshold, and the second In the above method, the micro base station A judges whether there is a service priority greater than or equal to the preset service priority in the service list of the small cell a, and at the same time judges whether the number of user equipment identifiers in the service list is greater than or equal to equal to the preset threshold.

Exemplarily, the micro base station A judging whether the small cell a satisfies the wake-up condition according to the first method above includes: the micro base station A judging whether there is a service priority greater than or equal to the preset service priority in the service list of the small cell a service priority. Assuming that the preset service priority is 6, since the service priority of the user equipment 1 is 5, the preset service priority 6 is greater than the service priority 5 of the user equipment 1, therefore, the micro base station A determines that the small cell a There is no service priority greater than or equal to the preset service priority in the service list, therefore, the small cell a does not meet the wake-up condition. It should be noted that the above method indicates that there is no service priority higher than the preset service priority in the first 4 user equipment information stored in the service list of the small cell a.

In particular, in practical applications, the micro base station will simultaneously determine whether the multiple small cells it manages meet the wake-up condition.

The micro base station A judging whether the small cell a satisfies the wake-up condition according to the second method above includes: the micro base station A judging whether the number of user equipment identifiers in the service list of the small cell a is greater than or equal to a preset threshold. Assuming that the preset threshold is 5, since 5 user equipment information are stored in the service list of the small cell a at the current moment, it can be judged that the number 5 of user equipment identities in the service list is equal to the preset threshold 5, Therefore, the small cell a satisfies the wake-up condition.

The micro base station A judging whether the small cell a satisfies the wake-up condition according to the second method above includes: the micro base station A judges whether there is a service priority greater than or equal to the preset service priority in the service list of the small cell a, and At the same time, it is determined whether the number of user equipment identities in the service list of the small cell a is greater than or equal to a preset threshold. The micro base station A judges by using the first method and the second method that there is no service priority in the service list of the small cell a that is greater than or equal to the preset service priority, and the service of the small cell a The number of user equipment identities in the list is equal to the preset threshold, therefore, the small cell a does not meet the wake-up condition.

304. When the small cell a satisfies the wake-up condition, the small cell a of the micro base station A enters the wake-up state.

Step 303 shows that the first method and the third method are used to determine that the small cell a does not meet the wake-up condition, and the second method is used to determine that the small cell a meets the wake-up condition. When the small cell a meets the wake-up condition, the micro base station A The small cell a can be woken up. The small cell a switches from the sleep state to the wake-up state, that is, the small cell a enters a normal working mode, and the small cell a can provide communication services for user equipments in the service list in the normal working mode.

Further, when the network device is an MME, as shown in FIG. 4, FIG. 4 is a control method for the user equipment 1 to wake up the small cell a, the micro base station A manages the small cell a, and the MME manages the micro base station A. The method includes:

401. The user equipment 1 sends a service request message to the MME, where the service request message includes the identifier of the user equipment 1 and a service priority, where the service priority is the service priority required by the user equipment for current communication.

402. The MME searches for a small cell meeting communication requirements for the user equipment 1 .

First, the MME receives the service request message sent by the user equipment 1; then, the MME searches for a small cell that meets the communication requirements for the user equipment 1. In practical applications, the MME searches for the user equipment 1 and the user equipment 1. A small cell that is closer and has better signal quality is used as a serving small cell, or a small cell that can provide services for the user equipment 1 is used as a serving small cell. The embodiment of the present invention assumes that the serving small cell found by the MME for the user equipment 1 is the small cell a.

403. The MME stores the user equipment identifier and the service priority in the service request message of the user equipment 1 into the service list of the small cell a.

404. The MME judges whether the small cell a satisfies the wake-up condition.

The method for the MME to judge whether the small cell a satisfies the wake-up condition may refer to the method for the micro base station A to judge whether the small cell a satisfies the wake-up condition in step 303, which will not be repeated here.

Then, according to step 303, it can be seen that the small cell a does not meet the wake-up condition determined by the first method and the third method, and the small cell a meets the wake-up condition determined by the second method.

405. When the small cell a meets the wake-up condition, the MME notifies the small cell a to enter the wake-up state.

According to step 404, it can be known that the small cell a does not meet the wake-up condition by using the first method and the third method, and the small cell a meets the wake-up condition by using the second method. Therefore, when the small cell a satisfies the wake-up condition, the MME may send a wake-up command to the small cell a to notify the small cell a to enter the wake-up state.

406. The small cell a enters the wake-up state.

The small cell a receives the wake-up command sent by the MME, the small cell a switches from the sleep state to the wake-up state, that is, the small cell a enters the normal working mode, and the small cell a can serve all user equipments in the service list in the normal working mode Provide communication services.

In this way, when there is a service priority in the service list that is greater than or equal to the preset service priority or when the number of user equipment identifiers in the service list is greater than or equal to the preset threshold, or the service list When there is a service priority with a service priority greater than or equal to a preset service priority and the number of user equipment identities in the service list is greater than or equal to a preset threshold, the network device controls the small cell corresponding to the service list to enter the wake-up state , which can prevent network devices from waking up multiple small cells, reducing energy consumption.

It should be noted that the order of the steps of the small cell sleep control method provided by the embodiment of the present invention can be adjusted appropriately, and the steps can also be increased or decreased according to the situation. Within, the method of change can be easily thought of, so I won't repeat them here.
