Lightweight MRRM with radio agnostic access selection in the core network
First Claim
1. An arrangement for making a handover decision in a multi-access communication network comprising a core network and at least one user terminal network communicating with said core network on at least two access paths via at least two access networks, whereby data sessions are routed on at least a first access path via a first access network and a second access path via a second access network, wherein the arrangement comprises:
- means for determining a first set of criteria for when a handover between said at least two access paths should be performed;
means for sending a first report when at least one criterion of said first set of criteria is fulfilled;
means for determining a second set of criteria for when a handover between said at least two access paths should be performed;
means for sending a second report when at least one criterion of said second set of criteria is fulfilled;
means for determining one or more data sessions of said at least one user terminal network to be handed over based on at least one of the sent first and second report;
means for executing a handover by re-routing said determined data sessions from one access path to an alternative access path.

Abstract
A method and arrangement for making a handover decision in a multi-access communication network is disclosed. A first set of criteria is determined for when a handover between at least two access paths should be performed and a report is sent when at least one criterion of a first set of criteria is fulfilled. A second set of criteria is determined for when a handover between said at least two access paths should be performed and a report is sent when at least one criterion of said second set of criteria is fulfilled. One or more data sessions of at least one user terminal network are determined to be handed over based on the sent reports and a core network anchor and a terminal anchor are directed to execute a handover by re-routing said determined data sessions from one access path to an alternative access path.

11. An arrangement in an access network for making a handover decision in a multi-access communication network comprising a core network and at least one user terminal network communicating with said core network on at least two access paths via at least two access network nodes, whereby data sessions are routed on at least a first access path via a first access network node and a second access path via a second access network node, wherein the arrangement comprises:
-
means for determining a set of criteria for when a handover between said at least two access paths should be performed; means for sending a report to a superior access selection function node when at least one criterion of said set of criteria is fulfilled, whereby said access selection function node is arranged to determine one or more data sessions of said at least one user terminal network to be handed over based on said sent report.

12. An arrangement in a user terminal network for making a handover decision in a multi-access communication network comprising a core network and at least one user terminal network communicating with said core network on at least two access paths via at least two access networks, whereby data sessions are routed on at least a first access path via a first access network and a second access path via a second access network, wherein the arrangement comprises:
-
means for determining a set of criteria for when a handover between said at least two access paths should be performed; means for sending a report to a superior access selection function node when at least one criterion of said set of criteria is fulfilled, whereby said access selection function node is arranged to determine one or more data sessions of said at least one user terminal network to be handed over based on said sent report.

13. An access selection function for making a handover decision in a multi-access communication network comprising a core network and at least one user terminal network communicating with said core network on at least two access paths via at least two access networks, whereby data sessions are routed on at least a first access path via a first access network and a second access path via a second access network, wherein the access selection function comprises:
means for receiving a report if at least one criteria for when a handover between said at least two access paths should be performed is determined means for determining one or more data sessions of said at least one user terminal network to be handed over based on said sent report, whereby a handover is executed by re-routing said determined data sessions from one access path to an alternative access path. - View Dependent Claims (14, 15)

16. A method for making a handover decision in a multi-access communication network comprising a core network and at least one user terminal network communicating with said core network on at least two access paths via at least two access networks, whereby data sessions are routed on at least a first access path via a first access network and a second access path via a second access network wherein the method comprises the steps of:
-
determining a first set of criteria for when a handover between said at least two access paths should be performed; sending a first report when at least one criterion of said first set of criteria is fulfilled; determining a second set of criteria for when a handover between said at least two access paths should be performed; sending a second report when at least one criterion of said second set of criteria is fulfilled; determining one or more data sessions of said at least one user terminal network to be handed over based on at least one of the sent first and second report; executing a handover by re-routing said determined data sessions from one access path to an alternative access path. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
