The RRC connection resume request message is used to request to resume an RRC connection of the terminal device. The method also includes sending a first message to a second network device. The first message includes auxiliary information. The auxiliary information includes at least one of information used by the terminal device to perform redirection or information used by the terminal device to perform cell reselection, or the auxiliary information indicates that the first network device cannot respond to the RRC connection resume request message of the terminal device. The method further includes receiving an RRC release message from the second network device. The method additionally includes sending the RRC release message to the terminal device.

Abstract: Provided are a system for implementing multiple Radio Access Networks (RANs) convergence and a method thereof. The method includes: an anchor RAN establishes a connection with a User Equipment (UE); the anchor receives a RAB establishment request from a Core Network (CN); the anchor RAN selects an auxiliary RAN; the anchor RAN sends quality of service (QoS) parameters to the auxiliary RAN, so that the auxiliary RAN establishes a connection with the UE according to the QoS parameters, while the anchor RAN keep the connection with the UE. With the methods provided in embodiments for the present disclosure, multiple RANs convergence is implemented, and the UE establishes connections with the anchor RAN and the auxiliary RAN at the same time, so as to improve the peak rate of the UE.

Abstract: A random access method and apparatus are provided. The method includes: a terminal device obtains a position of the terminal device and a position of a network device, the terminal device determines a time adjustment value based on the position of the terminal device and the position of the network device, and the terminal device sends a random access preamble based on the time adjustment value and a random access channel (RACH) resource configured by the network device. Based on this solution, the terminal device may determine the time adjustment value based on the position of the terminal device and the position of the network device, and adjust a time for sending the random access preamble on the RACH resource. This helps avoid a problem that random access preamble receiving time windows overlap, thereby increasing a success rate of accessing the network device by the terminal device.

Abstract: Embodiments of this application disclose a random access method and apparatus. In one example method, when a terminal device supports positioning, the terminal device may adjust, based on a positioning capability, time for sending a preamble on a RACH Occasion (RO) resource. When the terminal device does not support positioning, a corresponding RO resource periodicity may be configured to be large. Therefore, regardless of whether the terminal device supports positioning, a network device can receive, at the same time or in a short preamble receiving time window, preambles sent on a same RO resource, and receive, at different time, in different small time ranges, or in different short preamble receiving time windows, preambles sent on different RO resources.

Abstract: Embodiments of this application provide a communication method and an apparatus, relate to the communication field, and in particular, are applicable to a broadcast system. The method includes: A terminal device receives a first downlink channel from an access network device, where the first downlink channel is scrambled by using a first identifier and is used to carry first data. The terminal device receives a second downlink channel from the access network device, where the second downlink channel is scrambled by using a second identifier and is used to retransmit the first data. The first identifier and the second identifier are identifiers configured by the access network device. This method can implement a feedback retransmission mechanism combining broadcast initial transmission and partial retransmission, to further improve spectral efficiency of a communication system.
