Provision of location service apparatus

A method as claimed in any preceding claim, wherein the first set of information comprises one or more of the following:

• information about the communication system;
• co-ordinates of the sites;
• type of the transmitter and/or receiver apparatus used by the sites;
• identities of the sites;
• information of any site that is excluded from the possible sites;
• information about possible cells of the communication system;
• information about the capacity of the measurement unit;
• information about the radius of the measurement unit coverage;
• information of a threshold level for a cell measurement value.

A planning tool for defining sites for measurement units in a communication system, each of the measurement units providing a measurement coverage, the planning tool comprising:

• information storage means;
• first processor means for defining a first set of information that relates to one or more sites that are possible locations for the location measurement units and to the coverage provided by at least one of the sites if it is provided with a measurement unit;
• second processor means for defining a second set of information that relates to signalling conditions within the coverage of the one or more sites;
• third processor means for defining, based on the first and second sets of information, a third set of information that associates at least one of the possible sites with access entities of the communication system that are covered by said possible sites;
• and
• fourth processor means for selecting, based on the third set of information, sites for the location measurement units such that a predefined coverage is achieved.
