The present invention provides a service scheduling method and device. The service scheduling method of the present invention includes: separately determining a service type of a service on each bearer in a same preset time period, where each bearer has a same quality of service class identifier QCI, and types of the service type include: signaling, voice, and data; scheduling the service on eachbearer according to the service type of the service on the bearer and a preset scheduling sequence, where the preset scheduling sequence is: preferentially scheduling a signaling service, and then scheduling a voice service, and finally scheduling a data service. The present invention solves a problem that the signaling service and the voice service are not transmitted in time when data service traffic is large, and reduces a transmission delay of the signaling service and the voice service.

The invention discloses a voice service migration method, a voice service migration device, voice service migration equipment and a medium. The method comprises the steps of obtaining a call request initiated by a terminal; enabling a network node MME to send a scale value QCI1 bearer establishment request according to the call request; determining a cell where the terminal resides according to the call request, and determining a physical resource block PRB uplink interference average value of the cell; judging whether the PRB uplink interference average value of the cell is greater than a preset high-interference trigger circuit switched fallback (CSFB) threshold or not; if so, refusing the QCI1 bearer establishment request, so that the terminal triggers the CSFB to fall back to a 2G or 3G network of a second or third generation mobile communication technology, and the call request is established in the 2G or 3G network. According to the embodiment of the invention, the migration of the voice service can be realized, the situation that rescue is carried out after the voice quality is deteriorated is avoided, and the risks of service establishment failure and call drop are reduced.

To deal with the ever-growing demand for data service, the small cell network (SCN), a new structure network has been proposed. Although through spatial reuse SCNs may greatly increase the networks’ throughput, it may also lead to severe intra-layer interference and excessive handover (HO) overheads. Besides, the large-amount small cell scenery can also lead to severe network energy consumption. In the article, a dynamic power control scheme is proposed for small cells to handle the interference and HO problems. It can not only guarantee the cell edge users’ perception but also reduce the network energy consumption. The set of experiments in the big data analysis shows the scheme can bring a substantial growth in cell edge users’ throughput as well as decrease system outage probability.
