A method performed by a first node (111) is described herein. The first node (111) operates in a communications network (10). The first node (111) sends (204) a query to a second node (112) operating in the communications network (10). The query requests information on a location of a communication device (130) operating in the communications network (10). The communication device (130) is identified by the first node (111) as a constrained communication device (130) lacking a capability to query the second node (112). The first node (111) obtains (205) the information from the second node (112), in response to the sent query, and initiates updating (207) an object in the communication device (130) based on the obtained information. A method performed by the communication device (130) is also described, whereby the device sends (301), to the first node (111), an indication that it is constrained, and obtains (304) the update.
