US 9,544,829 B1 · Dynamic selection and use of handoff threshold

Abstract

A network node receives from a mobile terminal being served by a first coverage area a measurement report indicating signal level of a second coverage area detected by the mobile terminal. The network node then makes a determination, by considering PLMNs of the mobile terminal and of the coverage areas, of (i) whether the mobile node is a home mobile node of the first coverage area and (ii) whether the mobile node is a home mobile node of the second coverage area. Based on that determination, the network node then selects a handoff threshold. And based on the handoff threshold and the reported signal level, the network node decides whether to trigger handoff of the mobile terminal from the first coverage area to the second coverage area. The network node then triggers the handoff if the decision is to do so.

Dependent claims

A method comprising:

receiving into a network node a measurement report from a mobile terminal being served by a serving coverage area, wherein the measurement report specifies a signal level of a neighboring coverage area, and wherein the mobile terminal subscribes to service of a public land mobile network (PLMN);
making a determination by the network node of (i) whether the serving coverage area corresponds with the PLMN and (ii) whether the neighboring coverage area corresponds with the PLMN;
based on the determination, selecting by the network node a handoff threshold;
making a decision by the network node, based on the selected handoff threshold and the specified signal level of the neighboring coverage area, of whether to trigger a handoff of the mobile terminal from the serving coverage area to the neighboring coverage area;
and
triggering the handoff by the network node only if the decision is to trigger the handoff.

A method comprising:

wirelessly receiving into a first base station, from a mobile terminal served by the first base station, a measurement report indicating signal level of a second base station as determined by the mobile terminal;
making a determination, by the first base station, of (i) whether the mobile terminal is a home mobile terminal of the first base station and (ii) whether the mobile terminal is a home mobile terminal of the second base station;
based on the determination, selecting by the first base station a handoff threshold;
making a decision by the first base station, based on the selected handoff threshold and the specified signal level of the second base station, of whether to trigger a handoff of the mobile terminal from being served by the first base station to being served by the second base station;
and
triggering the handoff by the first base station only if the decision is to trigger the handoff.
