Description
Technical field
The present invention relates to the switching subsystem in CDMA (code division multiple access) mobile communication system, the method for chargeing behind particularly a kind of inter-system paging.
Background technology
CDMA mobile communication system comprises network entities such as MSC/VLR (mobile switching center), HLR (attaching position register), BSC (base station controller) and travelling carriage.
When inter-system paging is meant the lane place distributing paging of service MSC (travelling carriage registration MSC) under this MSC, paging request between edge MSC (and MSC of service MSC adjacency) transmitting system simultaneously, require edge MSC in corresponding adjoining position district also this travelling carriage of paging simultaneously.When travelling carriage after edge MSC paging success, call setup is to edge MSC.The 3GPP2ANSI-41D agreement has been stipulated two kinds of inter-system paging scheme: ISPAGE and ISPAGE2.The inter-system paging that this paper relates to only refers to ISPAGE2.
Chargeing based on customer location will be that following mobile-phone carrier branches out, the important means that attracts clients.Operator is according to position segmentation service district, and promptly the user has different charging regulations under different service areas, is embodied among user's the Profile (business list).The division minimum of service area is a unit with CELL (sub-district).Among user's the Profile,, also comprise the tabulation of the logical identifier and the corresponding individual character charging regulation corresponding to this user of newly-increased service area except original charging regulation (default Profile).When travelling carriage generation business operation, according to the current area of travelling carriage, obtain service area and individual character Profile, check that with this which kind of rule travelling carriage should charge by in this sub-district, promptly realizes the location based charging function.
Realize location based charging, MSC must know the sub-district at current mobile station place and the business list of the service area under this sub-district.In the ISPAGE2 scheme, after the inter-system paging success, show that the actual location of travelling carriage is in the coverage of edge MSC, but travelling carriage is not also initiated registration at edge MSC, does not have Profile information, can't be at edge MSC location based charging; And, also the positional information of edge MSC can't be delivered to service MSC, so also can't serve the MSC location based charging according to the message structure of the inter-system paging of existing ANSI41D protocol definition.
