Abstract
Examples in this application provide an identifier management method and apparatus. One example method includes receiving, by a first donor node, first indication information sent by a first node, where the first indication information indicates that the first node can be configured to provide a wireless backhaul service, and sending, by the first donor node to the first node, a first identifier, where the first identifier uniquely identifies the first node on a wireless backhaul link within a service range of the first donor node.
Claims12
An identifier management method, comprising:
- receiving, by a first donor node, first indication information sent by a first node to the first donor node, wherein the first indication information indicates to the first donor node that the first node is an integrated access and backhaul (IAB) node;
- in response to receiving the first indication information, obtaining, by the first donor node, a first identifier, wherein the first identifier includes an IP address of the first node that is allocated by an OAM to the first node;
- sending, by the first donor node, handover request information to a second donor node, wherein the handover request information requests to connect the first node to the second donor node;
- receiving, by the first donor node from the second donor node, identification information of the first node allocated by the second donor node, wherein the identification information of the first node is an adaptation layer identifier;
- and
- in response to receiving the identification information of the first node from the second donor node, sending, by the first donor node to the first node, a handover command, wherein the handover command carries the identification information of the first node;
- wherein the first donor node comprises a distributed unit (DU) and a centralized unit (CU), and wherein the method further comprises:
- receiving, by the DU, first configuration information sent by the CU, wherein the first configuration information comprises a first adaptation layer identifier of the first node and the IP address of the first node;
- receiving, by the DU, a first data packet sent by the CU, wherein the first data packet comprises the IP address of the first node and data;
- and
- sending, by the DU to the first node, a second data packet, wherein the second data packet comprises the IP address of the first node and the data.
A first donor node, comprising at least one processor and at least memory storing instructions, wherein the instructions are executed by the at least one processor to cause the first donor node to perform a method of:
- receiving first indication information sent by a first node to the first donor node, wherein the first indication information indicates to the first donor node that the first node is an integrated access and backhaul (IAB) node;
- in response to receiving the first indication information, obtaining a first identifier, wherein the first identifier includes an IP address of the first node that is allocated by an OAM to the first node;
- sending handover request information to a second donor node, wherein the handover request information requests to connect the first node to the second donor node;
- receiving, from the second donor node, identification information of the first node allocated by the second donor node, wherein the identification information of the first node is an adaptation layer identifier;
- and
- in response to receiving the identification information of the first node from the second donor node, sending, to the first node, a handover command, wherein the handover command carries the identification information of the first node;
- wherein the first donor node comprises a distributed unit (DU) and a centralized unit (CU), and wherein the DU is configured to:
- receive first configuration information sent by the CU, wherein the first configuration information comprises a first adaptation layer identifier of the first node and the IP address of the first node;
- receive a first data packet sent by the CU, wherein the first data packet comprises the IP address of the first node and data;
- and
- send a second data packet to the first node, wherein the second data packet comprises the IP address of the first node and the data.
