Mobility management
First Claim
Patent Images
1. A method, comprising:
- at a serving network access node, obtaining mobility management properties for a plurality of terminals served by the serving network access node,grouping at the serving network access node the plurality of terminals into groups based on correlating the obtained mobility management properties of the plurality of terminals,deciding on a necessity for a handover per group of terminals to form a decision, andforwarding information indicative of the decision from the serving network access node to a target network access node via a network interface established between serving network access node and the target network access node;
where the method further comprises invalidating, at the serving network access node, a decision on the necessity for handover for an individual terminal in a group, if the obtained mobility management properties of the individual terminal after the deciding do not necessitate a handover of the individual terminal; and
wheredeciding further comprises evaluating at the serving network access node a set of mobility management properties associated with a reference terminal, where the set of mobility management parameters associated with the reference terminal are mobility management properties that are received prior to other sets of mobility management properties associated with other terminals of the group.

Abstract
The present invention concerns mobility management. A method is proposed that involves obtaining mobility management properties for a plurality of terminals served by an access node, as well as grouping the plurality of terminals into groups based on correlating the obtained mobility management properties of the plurality of terminals. Decisions on the necessity for a handover are taken per group and then forwarded per group to a target access node. Also, a corresponding apparatus is proposed.

10. An apparatus, comprising:
-
a processor embodied at a serving network access node; and a memory embodied at the serving access node to store computer program code, where the computer program code is configured when executed by the processor to cause the serving network access node to perform, obtaining mobility management properties for a plurality of terminals served by the serving access node, grouping the plurality of terminals into groups based on correlating the obtained mobility management properties of the plurality of terminals, deciding on a necessity for a handover per group of terminals to form a decision, forwarding information indicative of the decision from the serving access node to a target access node via a network interface established between serving network access node and the target network access node; and invalidating, at the serving network access node, a decision on the necessity for handover for an individual terminal in a group at the serving network access node if the obtained mobility management properties of the individual terminal after the deciding do not necessitate a handover of the individual terminal to the target network access node;
wheredeciding further comprises evaluating at the serving network access node a set of mobility management properties associated with a reference terminal, where the set of mobility management parameters associated with the reference terminal are mobility management properties that are received prior to other sets of mobility management properties associated with other terminals of the group. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
