1. An apparatus of a location service control entity in a mobile network providing positioning reference signals for location determination, the apparatus comprising:
at least one processor;
at least one memory including computer program code; and
at least one interface configured for communication with at least another apparatus,
the at least one processor, with the at least one memory and the computer program code, being configured to cause the apparatus to perform:
deciding to suspend positioning reference signal transmission using a first positioning reference signal resource, and
configuring, upon a result of said deciding to suspend said positioning reference signal transmission, an access node supplying at least one location determination target with said positioning reference signal transmission using said first positioning reference signal resource, to suspend said positioning reference signal transmission,
wherein
the at least one processor, with the at least one memory and the computer program code, are configured to cause the apparatus to perform:
determining whether a suspension condition to suspend said positioning reference signal transmission is fulfilled, wherein
said deciding to suspend is based on whether said suspension condition is fulfilled,
wherein said positioning reference signal transmission using said first positioning reference signal resource is related to a continuous location service request of a positioning client node requesting said location determination of said location determination target, and
in relation to said determining whether said suspension condition is fulfilled, the at least one processor, with the at least one memory and the computer program code, being configured to cause the apparatus to perform:
receiving, from said location determination target, an indication to suspend said positioning reference signal transmission, or
receiving, from said location determination target, an indication that said location determination target does not utilize said positioning reference signal transmission, or
receiving, from said positioning client node requesting said location determination of said location determination target, a suspend message indicating to suspend said positioning reference signal transmission, or
receiving, from said access node, an indication that said access node is ready to suspend said positioning reference signal transmission, or
perceiving that a validity timer associated with said continuous location service request is expired.
