Abstract
Embodiments of this application disclose a random access method. The method includes: obtaining, by a first network device, resource information corresponding to a target service unit, where the resource information is used to indicate a resource to be used, by a user equipment (UE) that has established a connection to the first network device, to send a physical random access channel (PRACH) via the target service unit, and the target service unit is a cell to be accessed by the UE or at least one beam to be accessed by the UE; and sending, by the first network device, a notification message to the UE, where the notification message includes the resource information.
Claims20
A method, comprising:
- sending, by a first network device, a request message to a second network device, wherein the request message comprises a first identifier of a beam of the second network device;
- receiving, by the first network device, a response message responding to the request message from the second network device, wherein the response message comprises first information, wherein the first information comprises a second identifier of the beam and random access resource information associated with the second identifier of the beam, and the first identifier and the second identifier are the same or different identifiers of the beam;
- and
- sending, by the first network device, the first information to a user equipment (UE), wherein the first information enables the UE to initiate a random access to the second network device.
A method, comprising:
- sending, by a first network device, a request message to a second network device, wherein the request message comprises a first identifier of a beam of the second network device;
- receiving, by the second network device, the request message;
- sending, by the second network device, a response message responding to the request message, wherein the response message comprises first information, the first information comprises a second identifier of the beam and random access resource information associated with the identifier of the beam, and the first identifier and the second identifier are the same or different identifiers of the beam;
- receiving, by the first network device, the response message;
- and
- sending, by the first network device, the first information to a user equipment (UE), wherein the first information enables the UE to initiate a random access to the second network device.
A communications apparatus for a first network device, comprising:
- a memory;
- and
- a processor;
- wherein the memory is configured to store a computer program instruction, and when the computer program instruction is run on the processor, the computer program instruction causes the apparatus to perform the following:
- sending a request message to a second network device, wherein the request message comprises a first identifier of a beam of the second network device;
- receiving a response message responding to the request message from the second network device, wherein the response message comprises first information, wherein the first information comprises a second identifier of the beam and random access resource information associated with the second identifier of the beam, and the first identifier and the second identifier are the same or different identifiers of the beam;
- and
- sending the first information to a user equipment (UE), wherein the first information enables the UE to initiate a random access to the second network device.
A communications apparatus for a second network device, comprising:
- a memory;
- and
- a processor;
- wherein the memory is configured to store a computer program instruction, and when the computer program instruction is run on the processor, the computer program instruction causes the apparatus to perform the following:
- receiving a request message from a first network device, wherein the request message comprises a first identifier of a beam of the second network device;
- sending a response message responding to the request message to the first network device, wherein the response message comprises first information, wherein the first information comprises a second identifier of the beam and random access resource information associated with the second identifier of the beam, and the first identifier and the second identifier are the same or different identifiers of the beam.
