Wireless device communication using carrier priority

摘要

In systems and methods of wireless device communication using carrier priority, it is determined for a wireless device using a lower priority carrier that a signal strength of a higher priority carrier meets a signal strength criteria. It is further determined that a loading of the higher priority carrier meets a loading criteria. When the loading meets the loading criteria and the signal strength meets the signal strength criteria, a handover is performed of the wireless device from the lower priority carrier to the higher priority carrier.

主权项

1. A method of wireless device communication, comprising:
exchanging loading information between a first access node controlled by a first network operator and a neighboring access node controlled by a second network operator, the loading information being associated with a plurality of wireless devices communicating with the first access node using a first spectrum carrier and the neighboring access node using a second spectrum carrier; starting a timer at the first access node for a period of time; after the timer expires, determining that a maximum permitted delay of one or more wireless devices communicating with the first access node using the first spectrum carrier meets a priority associated with the second spectrum carrier of the neighboring access node, wherein the second spectrum carrier has a higher priority than the first spectrum carrier and comprises greater structure penetration characteristics than the first spectrum carrier, wherein the structure penetration characteristics of the first spectrum carrier and the second spectrum carrier are based on a throughout to the one or more wireless devices, an available modulation and coding scheme (MCS), and a location of the one or more wireless devices; determining, at the first access node, that a loading of the second spectrum carrier meets an overload criteria, the overload criteria being based on a capacity of the second spectrum carrier to support the one or more wireless devices communicating with the first access node using the first spectrum carrier and historical loading information of the second spectrum carrier; and performing a handover of the one or more wireless devices communicating with the first access node using the first spectrum carrier from the first spectrum carrier to the second spectrum carrier of the neighboring access node when a signal strength of the second spectrum carrier meets a signal strength criteria.
