METHODS AND APPARATUSES FOR TRIGGERING THE REPORTING OF NEIGHBOR RELATION INFORMATION
Various methods for triggering the reporting of neighbor relation information are provided. One example method may include causing neighbor cell relation information to be stored in association with a transition from a first radio access technology to a second radio access technology, and determining that a user equipment has idle mode signaling reduction enabled. The example method may also include in response to at least performing the transition and determining that the user equipment has idle mode signaling reduction enabled, causing a connection to be established to send a neighbor cell relation information indicator, which indicates that the neighbor cell relation information is available to be reported from a user equipment to a network entity. Similar and related example methods, example apparatuses, and example computer program products are also provided.

The apparatus of claim 7 , wherein the processing system configured to cause the connection to be established includes being configured to cause a radio resource control session to be initiated in response to the transition and determining that the user equipment has the idle mode signal reduction enabled.
11 . The apparatus of claim 7 , wherein the processing system is further configured to receive a request for the neighbour cell relation information from the network entity and cause the neighbour cell relation information to be sent to the network entity.
12 . The apparatus of claim 7 , wherein the processing system configured to cause neighbour cell relation information to be stored includes being configured to cause the neighbour cell relation information to be stored in association with the transition from the first radio access technology to the second radio access technology, the second radio access technology being a universal mobile telecommunications system terrestrial radio access (UTRA) technology.
13 . The apparatus of claim 7 , wherein the apparatus comprises a communications interface configured to wirelessly send the neighbour cell relation information indicator.
14 . A nontransitory computer readable medium having program code stored thereon, the program code, when executed, configures a processing system of a user equipment at least to:
cause neighbour cell relation information to be stored in association with a transition from a first radio access technology to a second radio access technology;
determine that the user equipment is implementing idle mode signalling reduction; and
in response to at least performing the transition and determining that the user equipment has idle mode signalling reduction enabled, cause a connection to be established to send a neighbour cell relation information indicator, which indicates that the neighbour cell relation information is available to be reported from the user equipment to a network entity.
15 . The computer readable medium of claim 14 , wherein the program code further configures the processing system to verify that the neighbour cell relation information is valid; and wherein program code that configures the processing system to cause the neighbour cell relation information indicator to be sent further configures the processing system to cause the neighbour cell relation information indicator to be sent in response to at least performing the transition and verifying that the neighbour cell relation information is valid.
