Abstract

Aspects of the disclosure relate to improve user equipment (UE) handover and mobility within a telecommunication network. Events that trigger a handover operation are defined by multiple thresholds corresponding to (and reflecting the requirements of) network-supported services. In one example, a base station detects an execution of a network-supported service at a UE and responsively transmits a threshold corresponding to the network-supported service to the UE. The UE monitors reference signals according to the threshold and transmits measurement reports if the thresholds are exceeded or satisfied. In some examples, at any given time, the UE monitors one or more thresholds corresponding to which (if any) network-supported services are presently being executed by the UE.

Dependent claims

A wireless communication node comprising at least one data processor and a memory storing instructions that, when executed by the at least one data processor, cause the wireless communication node to:

during a registration process for a wireless communication device with a communications network, transmit an indication of a first threshold to the wireless communication device,
wherein the first threshold defines an occurrence of a handover event with respect to at least one communications signal parameter;
detect that a first network-supported service is being executed at the wireless communication device based on a presence of a service-specific communication link between the communications network and the wireless communication device,
wherein the service-specific communication link is associated with the first network-supported service;
in response to detecting that the first network-supported service is being executed, transmit an indication of a second threshold to the wireless communication device,
wherein the second threshold is one of a plurality of pre-determined thresholds each associated with a respective network-supported service,
wherein the second threshold re-defines the occurrence of the handover event with respect to the at least one communications signal parameter;
receive, from the wireless communication device, an indication of the occurrence of the handover event based on the at least one communications signal parameter satisfying the second threshold while the first network-supported service is being executed;
and
perform at least one operation for a handover of the wireless communication device between cells of the communications network according to the handover event.

A wireless communication device comprising at least one data processor and a memory storing instructions that, when executed by the at least one data processor, cause the wireless communication device to:

monitor at least one signal parameter according to a first threshold that defines an occurrence of a handover event;
initiate an execution of a network-supported service;
in response to the execution of the network-supported service being initiated, receive an indication of a second threshold from a wireless communication node of a network supporting the network-supported service,
wherein the second threshold redefines the occurrence of the handover event with respect to the at least one signal parameter;
monitor the at least one signal parameter according to the second threshold during the execution of the network-supported service;
and
in response to the at least one signal parameter satisfying the second threshold during the execution of the network-supported service, generate and transmit a report to the wireless communication node,
wherein the report indicates the occurrence of the handover event.

5 more elements

At least one non-transitory computer-readable storage medium storing instructions that, when executed by at least one data processor, cause the at least one data processor to:

store a plurality of service-specific thresholds each defining an occurrence of a handover event with respect to a signal parameter and each corresponding to a network-supported service;
detect that a wireless communication device is executing one or more network-supported services;
select a particular service-specific threshold from a subset of service-specific thresholds that correspond to the one or more network-supported services being executed by the wireless communication device;
and
transmit, to the wireless communication device, an indication of the particular service-specific threshold to the wireless communication device,
wherein the indication causes the wireless communication device to monitor the signal parameter according to the particular service-specific threshold.
