Abstract
To reduce handover latency experienced by a user using a user equipment that is served for offloaded user data traffic by a first small cell, a handover between a first macro cell deploying the first small cell and a second macro cell deploying a second small cell is triggered when information indicating that the user equipment has associated with the second small cell not deployed by the first macro cell is received.
Claims8
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least:
- receive a first information indicating that a user equipment served with offloaded user data traffic by a first small cell has associated with a second small cell, the first small cell controlled by a first macro cell;
- detect that the second small cell is not controlled by the first macro cell;
- based on the detecting that the second small cell is not controlled by the first macro cell, trigger a handover of the user equipment from the first macro cell to a second macro cell controlling the second small cell;
- send a query to a network node maintaining mapping information on the user equipment having at least some user data offloaded from a macro cell to a small cell, the mapping information comprising at least some context information;
- and
- receive information comprising the context information in a query response.
