The number of messages required in networks where both location and presence services are deployed may be reduced, by retrieving presence data from messages otherwise intended to provide only location information. Thus, information determined in a location service scheme is utilized to provide a presence service as well. A location server requests mobile subscriber (MS) information from a Core Network (CN) Node (i.e. HLR, MSC, etc.) that can be used in determining the Location of the MS. A single message aggregates retrieval of information for two services, specifically, for both location and presence.
