1. A processor-implemented method for almanac version control, comprising:
reporting, by a mobile station (MS), a plurality of MS-held version identifiers to a server, wherein:
each MS-held version identifier corresponds to a distinct MS-held partitioned terrestrial radio resource almanac version of a plurality of MS-held partitioned terrestrial radio resource almanac versions, and,
each partitioned terrestrial radio resource almanac version corresponds to a geographical region and comprises assistance data to enable the MS to perform positioning based on signals received by the MS from one or more terrestrial radio sources in the geographic region corresponding to the partitioned terrestrial radio resource almanac version;
receiving, at the MS, in response to the plurality of MS-held version identifiers reported by the MS, information to enable the MS to determine whether to update one or more of the plurality of MS-held partitioned terrestrial radio resource almanac versions; and
determining, by the MS, based, in part, on the received information, whether to update the one or more of the plurality of MS-held partitioned terrestrial radio resource almanac versions.
