Abstract
An apparatus comprising means for performing: receiving, while connected to a first cell, preparation information for preparing the apparatus for a conditional handover of the apparatus to at least one other cell; receiving, from the first cell, a message, wherein the message causes the apparatus to transition from a connected state to an inactive state; receiving, from the first cell, information of a release condition; when it is determined that the release condition is met, sending a release indication and releasing the preparation information from the apparatus.
Claims16
An apparatus, comprising
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform:
- receiving, while connected to a first cell, preparation information configured to prepare the apparatus for a conditional handover of the apparatus to at least one other cell;
- receiving, from the first cell, a message, wherein the message is configured to cause the apparatus to transition from a connected state to an inactive state;
- receiving, from the first cell, information of a release condition;
- when it is determined that the release condition is met, sending a release indication and releasing the preparation information from the apparatus.
An apparatus, comprising
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code being configured to, with the at least one processor, cause the device at least to perform:
- sending, to a user equipment, preparation information configured to prepare the user equipment for a conditional handover to at least one cell;
- sending, to the user equipment, a message, wherein the message is configured to cause the user equipment to transition from a connected state to an inactive state;
- sending, to the user equipment, information of a release condition;
- and
- receiving, from the user equipment, a release indication for the at least one cell when it is determined that the release condition is met.
A method comprising:
- receiving, at an apparatus while connected to a first cell, preparation information configured to prepare the apparatus for a conditional handover to at least one other cell;
- receiving, from the first cell, a message, wherein the message is configured to cause the apparatus to transition from a connected state to an inactive state;
- receiving, from the first cell, information of a release condition;
- when it is determined that the release condition is met, sending a release indication and releasing the preparation information.
A method, comprising:
- sending, to a user equipment, preparation information configured to prepare the user equipment for a conditional handover to at least one cell;
- sending, to the user equipment, a message, wherein the message is configured to cause the user equipment to transition from a connected state to an inactive state;
- sending, to the user equipment, information of a release condition;
- and
- receiving, from the user equipment, a release indication for the at least one cell when it is determined that the release condition is met.
