摘要： Embodiments of the present disclosure relate to a method, a device and a computer-readable medium for guaranteeing communication service. According to embodiments of the present disclosure, a source network device that currently serves the terminal device transmits, to a target network device which will serve the terminal device, information about the amount of resources of network slices utilized by the terminal device. The target network device configures the amount of resources based on the information. In this way, successful handover of the terminal device from the source network device to the target network device is guaranteed, so as to ensure continuity of communication services of the terminal device. In addition, embodiments of the present disclosure creates a network slice in the target network device, which avoids possible interruptions of communication service caused by mapping from the terminal device to the slices supported by the target network device.

摘要： The inventors of the present invention desire to provide through at least one embodiment of the present invention, a method of and apparatus for transmitting uplink scheduling information that belongs to an unlicensed band from a network device to a user equipment. Through implementing the embodiments of the present invention, if a user equipment is to perform uplink transmission on an unlicensed band, it has to obtain uplink scheduling information from a network end; however, because strong resource contention might exist on the unlicensed band, if the uplink scheduling information is also transmitted over the unlicensed band, timely transmission of the information cannot be guaranteed. If the uplink scheduling information is transmitted over a licensed band whose resources are more guaranteed, its timely transmission can be assured, and the user equipment can obtain the information required by uplink transmission on the unlicensed band, coexistence of the LTE or LTE-A network with other networks or protocols such as Zigbee or Wi-Fi on the unlicensed band can be more effectively achieved.
摘要翻译：本发明的发明人期望通过本发明的至少一个实施例提供一种用于从网络设备向用户发送属于非授权频段的上行链路调度信息的方法和设备设备。通过实施本发明实施例，若用户设备要在非授权频段上进行上行传输，则必须从网络侧获取上行调度信息，但是由于非授权频段可能存在较强的资源争夺，所以如果上行调度信息也是通过未授权频段传输的，则无法保证信息的及时传输。如果通过资源更有保证的授权频段传输上行调度信息，可以保证其及时传输，用户设备可以获得非授权频段上的上行传输所需的信息，LTE或LTE-A网络共存与其他网络或协议如Zigbee或Wi-Fi无证书频段可以更有效地实现。
