Bearer handover control device and control method
First Claim
1. An apparatus, comprising:
- at least one processor; and
a memory storing a program;
wherein the program comprises computer code that when executed by the at least one processor causes the apparatus to carry out operations comprising;
receiving a bearer modification request message from a mobility management entity, wherein the bearer modification request message corresponds to one packet data network (PDN) connection of a user equipment, the bearer modification request message comprises bearer contexts corresponding to all the bearers in the PDN connection;
matching fully qualified tunnel endpoint identifiers (F-TEIDs) in the bearer contexts in the bearer modification request message with F-TEIDs in bearer contexts that are stored in the memory;
determining that a bearer with changed F-TEID is a bearer needing to be handed over to a target base station; and
sending an end marker message to a source base station only for the bearer needing to be handed over.

Abstract
Embodiments of the present invention disclose a bearer handover control device and control method. The method includes: receiving, by a network side device, a bearer handover message; and determining, by the network side device according to the bearer handover message, a bearer needing to be handed over in all bearers, so that an end marker End Marker message is sent to a source base station only for the bearer needing to be handed over. By using the foregoing solutions, for a multi-connection scenario, a network side device can determine a bearer needing to be handed over, so that an end marker message is sent only for the bearer needing to be handed over, which can prevent discarding of subsequent data of a bearer that is not to be handed over, and ensure multiple connections between a UE and base stations, thereby improving stability of a system.
