Description
Technical field
Relate generally to mobile communication of the present invention is specifically related to the charging method of prepayment user to send SMS upon cross-network roaming.
Background technology
At present, in the mobile network, the prepaid user does not realize internetwork roaming, thus the prepaid user can't be under the internetwork roaming state short-message sending.If the prepaid user roams into other carrier networks and sends SMS message, the MSC (mobile switching centre) on the ground of being interviewed sends MAP-MO-FORWARD-SHORT-MESSAGE (MAP changes short message before starting) message and gives the short message service center of ownership place.Present short message service center can not judge this message from which network is sent, and can not judge that this user is prepaid user or postpaid service user, thereby has the problem of chargeing.
Present stage,, mainly contain following dual mode if realize that the prepaid user sends SMS message under the internetwork roaming state.First kind of CAMEL (mobile network strengthens the customized application of logic) 3 mode that mode is the employing standard.Just when the user roams into other carrier networks, if the zone network of being interviewed is supported CAMEL3, so, the be interviewed SSP (Service Switching Point) on ground and the SCP (service control point) of ownership place carry out alternately, the authentication of finishing the user with deduct fees.In this manner, the zone network of being interviewed need be supported CAMEL3.Yet present GSM (global system for mobile communications) network is only supported CAMEL2.WCDMA (Wideband Code Division Multiple Access (WCDMA))/TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) does not carry out Interoperability Testing though network is supported CAMEL3 between the different operators, therefore be difficult to realize prepaid user's roaming.To be operator adopt independent number segment to the prepaid user to the second way when carrying out sign indicating number number planning, to make a distinction with the postpaid service user.In this manner, the user is behind the ground short-message sending of being interviewed, and short message is sent back to home network short message service center by signaling network, and short message service center triggers the charging that corresponding SCP carries out caller according to number segment.But in this manner, operator need keep independent number segment for the prepaid user, and the user can not independently select way of paying, changes between can not paying in pre-payment and back.
Above dual mode can be realized the short message service of prepaid user when internetwork roaming in theory, but operability is not strong, and the former needs to cooperate between the operator, and the latter lacks flexibility.
Summary of the invention
For addressing the above problem, the present invention proposes to have the method that is used to realize the short message service of prepaid user when internetwork roaming of strong operability.
According to a first aspect of the invention, propose a kind of ownership place short message service center and judge that the user that sends SMS message is whether in the method for internetwork roaming, wherein, after the MAP-MO-FORWARD-SHORT-MESSAGE message that this user sends is received by ownership place short message service center, whether GT (overall identification) number by transmit leg in SCCP (SCCP) layer of analyzing this message judges this message from other carrier networks, thereby judges that whether this user is at internetwork roaming.
According to a second aspect of the invention, propose a kind of ownership place short message service center and obtain method at internetwork roaming and the user's that sends SMS message Originating CAMEL Subscription Information, wherein, ownership place short message service center adopts the restore data flow process of MAP (MAP) agreement to obtain this user's Originating CAMEL Subscription Information.
According to a third aspect of the invention we, a kind of charging method that sends SMS message when the internetwork roaming for the prepaid user is proposed, may further comprise the steps: after the MAP-MO-FORWARD-SHORT-MESSAGE message that this user sends is received by ownership place short message service center, whether judge this message from other carrier networks by the GT number of transmit leg in the SCCP layer of analyzing this message, thereby judge that whether this user is at internetwork roaming; If judge this user at internetwork roaming, then ownership place short message service center adopts the restore data flow process of MAP to obtain this user's Originating CAMEL Subscription Information; Whether comprise MO-SMS-CSI (the short message service CAMEL-Subscription-Information starts) in this user's that judgement is obtained the Originating CAMEL Subscription Information; Comprise MO-SMS-CSI if judge in the described Originating CAMEL Subscription Information, determine that then this user is the prepaid user, ownership place short message service center and ownership place SCP handle this short message according to pre-payment processing method in the net then alternately so that this short message is chargeed.
According to said method of the present invention, when the prepaid user roams into other carrier networks and sends SMS message, this user's ownership place short message service center can easily judge this user at internetwork roaming and be the prepaid user, thereby charges according to pre-payment processing method in the net.
