Abstract: Embodiments of the present application relate to the technical field of wireless communications, and in particular, to a method, a device and a system for transmitting a data packet, which are used to resolve the problem existing in the prior art that an LTE network structure causes a signaling burden on a backhaul between a radio access network and a core network and causes a transmission delay on the backhaul. In the embodiments of the present application, a control point sends a data packet that is from at least one base station to an access network gateway or a core network gateway; and a data packet that is from the access network gateway or the core network gateway is sent to the at least one base station, the control point being a connection control point of a terminal and a mobility control point of the terminal. In the embodiments of the present invention, a control plane signaling process of a core network of a new network architecture is greatly simplified; therefore, the control delay and traffic pressure on a Backhaul between an access network and a core network are reduced. Under the control of a control point, a transmission mode is flexibly selected at an access network side, so that requirements of different services on aspects of the delay and reliability can be met.

Abstract: A method and an apparatus for maintenance of a bandwidth part. The method and apparatus resolve an issue of the prior art in which expiration of a bandwidth part deactivation timer during a random access process changes the bandwidth part to a default bandwidth part, such that data cannot be transmitted on an optimal bandwidth part, and may even cause an interruption of an ongoing data transmission, while also affecting an ongoing random access process. In embodiments of the present invention, a terminal keeps a current active bandwidth part unchanged during a random access process, and performs a restart operation of a bandwidth part deactivation timer after the random access process is successfully completed, such that a situation where a bandwidth part changes to a default bandwidth part does not occur during the random access process, thereby reducing interruption to ongoing data transmissions and reducing the impact on ongoing random access processes.

Abstract: The present disclosure relates to a method and a device for responding to a random access. The method includes: a user equipment (UE) sending a random access request, wherein information including a UE identifier is carried in the random access request; and the UE receiving a random access response, wherein when UE identifier carried in the random access response is consistent with the UE identifier in the random access request, a contention resolution is completed; when the UE identifier carried in the random access response is inconsistent with the UE identifier in the random access request, the UE determines that the random access fails this time, and re-initiates a random access attempt; and when no UE identifier is carried in the random access response, the UE falls back to a random access process in which no UE identifier information is carried in the random access request.
