Abstract: Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping. In one embodiment, a base station adds a component carrier (CC) for a user equipment (UE). The base station determines a timing advance (TA) group to which the added CC belongs. The TA group is a set of CCs that can share a TA. The base station sends identification information that identifies the TA group to the UE.

Abstract: Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping, and relate to the field of communications, the method, device and system for determining timing advance grouping. The method includes adding, by a base station (eNodeB), a component carrier (CC) for a user equipment (UE); according to obtained timing advance (TA) group information or a preset rule, determining a TA group that the added CC belongs to, where the TA group is a set of CCs that can share a TA; and sending identification information that identifies the TA group to the UE. Embodiments of the present invention are used to determine TA grouping when the eNodeB adds the CC for the UE.

Abstract: The embodiments of present invention provide a mobile communications method, a device, and a system. The method is performed by an access network device, including: receiving, by using a terrestrial interface of a first network standard between an access network and a first core network, a first terrestrial interface message of the first network standard sent by the first core network; generating, according to an air interface protocol of an air interface of a second network standard between the access network and UE and the first terrestrial interface message, a first air interface message of the second network standard; and sending, by using the air interface of the second network standard, the first air interface message to the UE. The method implements direct communication between network devices of different standards in a mobile communications system, thereby decoupling an air interface from a terrestrial interface.
