Abstract:
Embodiments of the present invention disclose a communication method, a source base station, a target base station, a core network device, and a terminal device, where the method includes: receiving, by an access network device, a first message from a first core network device; receiving, by the access network device, a second message from a second core network device; receiving, by the access network device, a third message from a terminal device; and selecting, by the access network device, a core network device to service the terminal device.
Abstract:
Embodiments of this application provide a communication method, an apparatus, and a system. In this solution, after determining that a connection failure occurs, a terminal device records and sends a first report. The first report includes cell information of a first logical cell, or the first report includes a PLMN identifier of a first logical cell and cell information of a second logical cell. The first logical cell includes a source logical cell and/or a failed logical cell in which the connection failure occurs. The second logical cell includes a 1st logical cell that shares a same physical cell with the source logical cell and/or a 1st logical cell that shares a same physical cell with the failed logical cell. Based on this, a connection failure rate of the terminal device in a RAN sharing scenario can be reduced, and a handover success rate can be improved.
Abstract:

Abstract:
A method and apparatus of allocating a Physical Cell Identifier (PCI) is disclosed in an embodiment of the present invention allowing different cells to operate on different frequencies while eliminating or reducing risk of PCI conflicts. Thereby PCI allocation is provided that is effective also in a multi-frequency environment.
Abstract:
A method of the embodiments of the present invention includes: sending, by a source base station, identifier information to a user equipment, where the identifier information carries an identifier of a CIO configuration reason, and receiving, by the source base station, a first radio link failure indication sent by a first target base station, where the first radio link failure indication is sent by the first target base station to the source base station after the first target base station receives a Radio Resource Control protocol RRC reestablishment request message sent by the user equipment, and the RRC reestablishment request message carries the identifier of the CIO configuration reason.
Abstract:
In a communication method, a first network node sends a first message to a second network node, where the first message includes first configuration information. The first network node receives a second message from the second network node, where the second message includes second configuration information determined based on the first message. The first network node includes at least one of a packet data convergence protocol layer, a service data adaptation protocol layer, or a radio resource control protocol layer. The second network node includes at least one of a radio link control protocol layer, a media access control layer, or a physical layer.
Abstract:
This application discloses a communication method, apparatus, and system, so that a load balancing function between network elements is improved and enhanced, and an exchange process is simple, direct, and effective. In the method, a first network device sends a message requesting to change a mobility parameter, wherein the message is at a beam granularity.
Abstract:
A first network node is configured to: group served cells into a first set of cells and at least one second set of cells, the cells in the first set of cells being associated with a first set of cell information and cells in the second set of cells being associated with a second set of cell information; generate a setup request including a first indication indicating the first set of cells and their respective first set of cell information and the second set of cells and their respective second set of cell information; and transmit the setup request to the second network node. The second network node is configured to receive a setup request from a first network node, the setup request including a first indication.
Abstract:
Embodiments of the present invention disclose a communication method, a source base station, a target base station, a core network device, and a terminal device, where the method includes: sending, by a source base station, a handover request to a target base station, where the handover request is used to request to hand over a session of a terminal device from the source base station to the target base station, and the handover request includes an identifier of a session requested to be handed over and indication information of a network slice corresponding to the session; and receiving, by the source base station, a handover response message from the target base station.
