Network node data scheduling method, apparatus, and system

User equipment, comprising:

• an obtaining module, configured to:
• obtain system information of multiple micro network nodes in a current serving micro network node group, and extract first system information of a serving micro network node of the user equipment from the system information;
• a processing module, configured to determine a first shared carrier of the serving micro network node group according to the first system information obtained by the obtaining module;
• a transmission module, configured to transmit, according to the first system information by using the first shared carrier, service data in a serving cell covered by the serving micro network node;
• wherein the obtaining module is further configured to:
• when it is determined that a preset cell handover condition is met, hand over to a target cell, and obtain second system information of a target micro network node corresponding to the target cell;
• and
• wherein the transmission module is further configured to transmit the service data in the target cell according to the second system information by using a second shared carrier of a micro network node group to which the target micro network node belongs.

A base station, comprising:

• a processing module, configured to combine multiple micro network nodes in a preset physical area into one micro network node group according to a preset policy;
• and
• a sending module, configured to send configuration information of the micro network node group to each micro network node in the micro network node group obtained by the processing module by means of combining, so that each micro network node configures the micro network node according to the configuration information, and broadcasts system information of the micro network node on a shared carrier of the micro network node group, and user equipment moving in the micro network node group extracts first system information of a serving micro network node of the user equipment from the system information, determines a first shared carrier of a serving micro network node group according to the first system information, and transmits, by using the first shared carrier, service data in a serving cell covered by the serving micro network node;
• when it is determined that a preset cell handover condition is met, the user equipment hands over to a target cell, obtains second system information of a target micro network node corresponding to the target cell, determines, according to the second system information, a second shared carrier of a micro network node group to which the target micro network node belongs, and transmits the service data in the target cell by using the second shared carrier.
