Identifying coverage holes using inter-rat handover measurements
First Claim
1. One or more non-transitory computer readable media having program code that, when executed by one or more processors, causes a Coverage and Capacity Optimization (CCO) function to:
- determine a coverage hole based on obtained measurement data, wherein the measurement data is associated with coverage areas of one or more evolved universal terrestrial radio access network (E-UTRAN) cells that provide connectivity to a Long Term Evolution (LTE) network and the measurement data includes inter-radio access technology (RAT) measurements, and wherein the coverage hole is an area with insufficient signal strength to provide reliable connectivity to the LTE network; and
send an instruction to alter a service parameter of at least one E-UTRAN cell of the one or more E-UTRAN cells to increase connectivity to the LTE network in the coverage hole area.

Abstract
Embodiments of systems and techniques for identifying coverage holes in a radio access technology (RAT) are described. In some embodiments, a network management (NM) apparatus may receive a first report, including one or more measurements taken by a first user equipment (UE), in response to an event related to a handover of the first UE between a first radio access technology (RAT) and a second RAT different from the first RAT. The NM apparatus may receive a second report including one or more measurements taken by a second UE in response to an event related to a handover of the second UE between the first RAT and a third RAT different from the first RAT. The NM apparatus may identify a hole in a coverage area of the first RAT based at least in part on the first and second reports. Other embodiments may be described and claimed.

9. A network management (NM) apparatus to implement a Coverage and Capacity Optimization (CCO) function, the apparatus comprising:
-
communications circuitry to receive, from one or more evolved nodeBs (eNBs), measurement data of one or more evolved universal terrestrial radio access network (E-UTRAN) cells provided by the one or more eNBs, wherein each E-UTRAN cell is to provide connectivity to a Long Term Evolution (LTE) network, and wherein the measurement data is based on measurements performed during handovers from each E-UTRAN cell to other cells provided by radio access technologies (RATs) different than E-UTRAN; and processor circuitry to identify an E-UTRAN coverage hole based on the measurement data, and determine an E-UTRAN coverage area to be adjusted based on the E-UTRAN coverage hole, and wherein the communications circuitry is to transmit, to at least one eNB of the one or more eNBs, an instruction to adjust a service parameter of an E-UTRAN cell provided by the at least one eNB to adjust the E-UTRAN coverage area. - View Dependent Claims (10, 11, 12, 13, 14)

15. One or more non-transitory computer readable media having program code that, when executed by one or more processors, causes an evolved nodeB (eNB) to:
-
receive measurement data from one or more user equipment (UEs), wherein the measurement data includes inter-radio access technology (RAT) measurements; transmit the measurement data to a Coverage and Capacity Optimization (CCO) function of a network management (NM) apparatus; receive, from the CCO function, an instruction to adjust a service parameter of a cell coverage area based on the measurement data, wherein adjustment of the service parameter is based on an identified coverage hole indicative of a reduction in connectivity to a Long Term Evolution (LTE) network; and adjust the service parameter to provide an increase in connectivity to the LTE network in the coverage hole area. - View Dependent Claims (16, 17, 18, 19, 20)
