1. A mobile terminal comprising:

  • at least one antenna;

    at least one Global Positioning System (GPS) receiver;

    at least two different applications;

    wherein each of the at least two different applications is executable on the mobile terminal,the mobile terminal configured to wirelessly transmit information to and wirelessly receive information from a mobile communication network;

    the mobile terminal further configured to use positioning data from a plurality of positioning methods including at least a GPS method and a Wireless Local Area Network (WLAN) positioning method;

    at least one processor; and

    at least one memory including computer program code,the at least one memory and the computer program code being configured, with the at least one processor, to cause the mobile terminal at least to;

    receive positioning data associated with at least two of the plurality of positioning methods;

    store the received positioning data;

    determine if the stored positioning data meets one or more conditions associated with positioning data used by at least one of said at least two different applications,and if not, select at least one of said plurality of positioning methods in dependence on the one or more conditions associated with positioning data requested by said at least one of said at least two different applications to provide positioning data for combining with positioning data provided by at least one other one of said plurality of positioning methods;

    perform a combining of stored positioning data received from said at least one selected one of said plurality of positioning methods and said at least one other one of said plurality of positioning methods to form combined positioning data;

    store said combined positioning data, whereby said stored combined positioning data is made available to said at least two different applications,wherein said one or more conditions associated with positioning data comprise a set of one or more parameters indicative of a quality of the positioning data,wherein, the causing of the mobile terminal to at least select at least one of said plurality of positioning methods comprises the mobile terminal being caused to at least;

    select, responsive to one of said at least two different applications requesting positioning data associated with said one or more conditions, at least two positioning methods, each of said at least two positioning methods providing positioning data for combining to form said combined positioning data conforming with the one or more conditions associated with the requested positioning data;

    centrally manage for the at least two different applications the stored combined positioning data associated with said plurality of positioning methods; and

    andmake available said centrally managed combined positioning data to at least one application of the at least two different applications.
