Abstract
The embodiments of the present invention disclose a user equipment migration method and device to implement flexible migration of UE in a core network device pool. The method includes that a source core network device receives a migration instruction carrying first identification information of a target core network device and migration information of to-be-migrated UE, sends an indication message used to instruct the to-be-migrated UE to detach, and sends a migration rule to an access network device according to the migration instruction, so that the access network device migrates the to-be-migrated UE from the source core network device to the target core network device.
Claims18
A core network device, comprising:
- a processor;
- and
- a memory coupled to the processor, wherein the memory stores processor-readable instructions which when executed cause the processor to implement operations including:
- receiving a migration instruction sent by a core network management device, wherein the migration instruction carries first identification information of a target core network device and migration information of a to-be-migrated user equipment (UE);
- sending to the to-be-migrated UE an indication message, according to the migration information of the to-be-migrated UE, wherein the indication message is used to instruct the to-be-migrated UE to detach;
- and
- sending a migration rule to an access network device according to the migration instruction, so that an access network device migrates, according to the migration rule, the to-be-migrated UE from a source core network device to the target core network device, wherein the migration rule comprises identification information of the source core network device and second identification information of the target core network device.

An access network device, comprising:
- a processor;
- and
- a memory coupled to the processor, wherein the memory stores processor-readable instructions which when executed cause the processor to implement operations including:
- receiving a migration rule sent by a source core network device, wherein the migration rule comprises identification information of a target core network device and identification information of the source core network device;
- and
- migrating, according to the migration rule, a to-be-migrated user equipment (UE) from the source core network device to the target core network device,
- wherein the operations also include:
- receiving an access request message sent by the to-be-migrated UE before the to-be-migrated UE is migrated from the source core network device to the target core network device, wherein the access request message carries identification information of a core network device to which the to-be-migrated UE is connected;
- and
- when determining that the identification information of the core network device to which the to-be-migrated UE is connected and the identification information of the source core network device are the same, migrating, according to the migration rule received by the receiving module, the to-be-migrated UE from the source core network device to the target core network device.
