Path switch method for dual connectivity in wireless communication system and apparatus for same
First Claim
1. A method of determining a path switch for dual connectivity of a first network entity in a wireless communication system, comprising:
- receiving bearer setup information containing a bearer type for at least one or more bearers;
transmitting a path switch request to a second network entity based on the bearer setup information;
receiving a path switch response from the second network entity in response to the path switch request; and
determining a path switch according to whether or not the path switch response indicates admission of a default bearer,wherein the first network entity corresponds to a MeNB (master eNB), andwherein the second network entity corresponds to a SeNB (secondary eNB).

Abstract
The present invention relates to a method and an apparatus for determining a path switch in a wireless communication system. Specifically, the present invention relates to a method for determining a path switch of a first network entity, the method comprising the steps of: receiving bearer setup information including a bearer type regarding at least one bearer; transmitting a path switch request to a second network entity on the basis of the bearer setup information; receiving a path switch response corresponding to the path switch request from the second network entity; and determining a path switch depending on whether the path switch response indicates admission of a default bearer.

8. A first network entity determining a path switch for dual connectivity in a wireless communication system, comprising:
-
a radio frequency (RF) unit; and a processor, wherein the processor is configured to; control the RF unit to receive bearer setup information containing a bearer type for at least one or more bearers; control the RF unit to transmit a path switch request to a second network entity based on the bearer setup information; control the RF unit to receive a path switch response from the second network entity in response to the path switch request; and determine a path switch according to whether or not the path switch response indicates admission of a default bearer, wherein the first network entity corresponds to a MeNB (master eNB), and wherein the second network entity corresponds to a SeNB (secondary eNB).
