A method for accounting the fee of soft-switching roaming includes judging if the soft switching takes place in mobile telephone according to the soft switch information recorded in source base station (BS), recording the result and relative soft switch information in the taking list of source MSC, judging if the soft-switching roaming takes place according to said talking list and destination mobile switch senter ID (MSCID), and accounting its fee if it does or not accounting if it does not.
Description
Technical field
The present invention relates to the charging method of mobile communication system, particularly the charging method of roaming about soft handover in code division multiple access (CDMA) system.
Background technology
In the cdma network structure of 3GPP2 definition, A3/A7 interface between base station (BS) is used for realizing the soft handover between the BS: mobile phone is set up at source base station (BS) and is called out, mobile phone enters the area of coverage of purpose BS in communication process, this moment, source BS can be that mobile phone is set up Radio Link by A3/A7 interface requests purpose BS, to improve speech quality and to keep conversation.
Referring to shown in Figure 1, moving exchanging center MSC 1, MSC2 belong to different operators or different roam charges district; When not having the A3/A7 interface between dotted line 1 expression BS, system carries out the Business Stream after the direct-cut operation roaming, when between dotted line 2 expression BS the A3/A7 interface being arranged, and the Business Stream after the soft handover roaming.
If do not have the A3/A7 interface between source BS and the purpose BS, then can not carry out soft handover between BS.In order to make mobile phone call drop not when striding BS, source BS can initiate direct-cut operation and transfer the call among the purpose BS.Because MSC1 belongs to different operator or message areas with MSC2, so roaming taken place from position 1 direct-cut operation in MS to the process of position 3 when conversation, is called " direct-cut operation roaming ".
If between source BS and the purpose BS A3/A7 interface is arranged, 1 place in the position, MS sets up in the area of coverage of source BS and calls out and enter talking state, and this moment, all Radio Links all were based upon among the BS of source; MS moves to position 2, is in the source BS and the overlapping area of coverage of purpose BS, and this moment, source BS was that MS sets up Radio Link through A3/A7 interface requests purpose BS, and MS has Radio Link in source BS and purpose BS; MS moves to position 3, and this moment, MS stepped out the area of coverage of source BS, switched to purpose BS fully, and all Radio Links of MS are based upon among the purpose BS.Because MSC1 belongs to different operator or message areas with MSC2, so roaming taken place in MS from the soft switching process of position 1,2,3 in communication process, is called " soft handover roaming ".
At present, belong to the mobile phone in different operators or different provinces, when roaming took place mobile phone, the charging center was according to chargeing to its roaming, and all roaming informations all are recorded in the ticket, and referring to shown in Figure 2, the process that produces ticket is as follows:
Step 20 1, mobile phone are finished soft handoff procedure (Soft Handoff Procedure).
Step 202, source BSC send Handoff Performed message by the A1 interface to source MSC, are used to notify the Active Set cell ID (ID) of MSC current phone.
After step 203, MSC receive Handoff Perdormed message, first sub-district of Cell Identidier List in this message is recorded in the ticket as designated cell (Designated Cell) and with it, and MSC passes to the charging center with the ticket that produces and charges.
From above-mentioned steps as can be seen, Handoff Performed message only is used for usertracking, does not have the foundation as roam charge.And have only a sub-district (Designated Cell) information in the ticket, the charging center can't judge whether to take place the soft handover roaming exactly according to Designated Cell, so prior art can not realize the charging to the soft handover roaming.
But, because when the soft handover roaming takes place, mobile phone has used the Radio Resource of purpose BS fully, the user has roamed into other operators or area, and present charge system is not considered the soft handover roaming, can not solve the charging problem of soft handover roaming, thereby cause operator can not collect rational roaming charges, lose some deserved economics well-being of workers and staff.
Summary of the invention
In view of this, the invention provides a kind of soft handover roam charging method, when making mobile phone that the soft handover roaming take place in communication process, charge system can detect the generation of roaming, and starts the charging to roaming, for operator brings deserved income.
A kind of soft handover roam charging method is to realize like this.
A. according to the soft handover information that writes down in the source base station, whether the judgement mobile phone soft handover takes place, and court verdict and relevant soft handover information are recorded in the ticket of source mobile switching centre (MSC);
B. the charging center judges whether to take place the soft handover roaming according to ticket and the purpose mobile switching centre sign (MSCID) of source MSC, if take place, then carry out soft handover and charge, otherwise, do not carry out soft handover and charge.
Described steps A is that source MSC adjudicates mobile phone according to source base station information of cell identifier list (Cell Identifier List) in the Handoff of its transmission Performed message whether soft handover takes place.
Described Handoff Performed message source base station when taking place to switch between BS sends to source MSC through the A1 interface.
Described Cell Identifier List comprises CellIdentifier List sign, length, cell ID description (Cell Identification Discriminator) and cell ID (CELL ID), and, when Cell Identification Discriminator is 02H, CELL ID comprises sub-district (CELL) and sector (Sector), when Cell Identification Discriminator was 07H, CELL ID further comprised mobile switching centre's sign (MSCID).
Adjudicate mobile phone when whether soft handover taking place when the Handoff Performed message that sends to source MSC according to source base station, described steps A comprises:
A11. source MSC judges whether the Cell IdentificationDiscriminator in the Handoff Performed message is 07H, if all the MSCID with this MSC is different for the pairing MSCID of all Cell ID among the Cell Identifier List, mobile phone switches to non-source MSC fully, the pairing MSCID of first Cell ID is recorded in the ticket, and provide and switch indication and switching time, otherwise, execution in step A12;
A12. get first Cell ID among the Cell Identifier List, this Cell ID is recorded in the ticket.
Described steps A comprises:
Whether A21.BSC switches to the purpose base station fully according to the information judgement mobile phone of record, and will comprise at least that MSCID and the soft handover time of court verdict, the affiliated MSC in purpose base station are sent to source MSC;
A22. source MSC writes down MSCID and the soft handover time of MSC under court verdict and the purpose base station in ticket.
MSCID that comprises court verdict and the affiliated MSC in purpose base station at least described in the steps A 21 and the information of soft handover time send a newly-increased message to source MSC and transmit.
Described newly-increased message is that source base station passes through the A1/A2 interface and sends to source MSC.
Described newly-increased message parameter comprises that soft handover takes place between type of message, MSC fully indicates and purpose MSCID.
Relevant soft handover information described in the steps A comprises to be switched indication and switching time.
Whether the present invention by the recorded information judgement mobile phone that has among the BS soft handover roaming takes place, and charges for the mobile phone that the soft handover roaming takes place, and this method is simple, easy to implement, for operator brings rational economic well-being of workers and staff.

Embodiment
The present invention carries out the soft handover roam charge at the mobile phone that cdma system carries out soft handover.
Need to prove, if when mobile phone is conversed in the overlapping area of coverage of two BS, be not real roaming, if press roam charge this moment, to mobile subscriber's unfairness.Therefore, the charging principle of soft handover roaming is: only switch to BS under the purpose MSC fully when mobile phone, just can start the soft handover roam charge; In addition, should charge according to non-roaming.
Referring to shown in Figure 3, realize that method of the present invention may further comprise the steps:
Step 301, according to the soft handover information of record in the source base station (BS), whether the judgement mobile phone soft handover takes place, and court verdict and relevant soft handover information are recorded in the ticket of source MSC;
Describe technical scheme of the present invention in detail for embodiment one below.
Present embodiment is that MSC is by detecting the Cell ID of Cell Identifier List in the Handoff Performed message, whether complete soft handover is to other MSC to judge mobile phone, in ticket, increase corresponding information then, judge whether to take place the soft handover roaming by the charging center at last, and roaming is chargeed to soft handover.
The Handoff Performed message parameter that defines among the A.S0014 once at first is described, ginseng is shown in Table 1, and Handoff Performed message parameter comprises type of message (Message Type), reason (Cause), cell identifier list (Cell Identifier List), channel number (ChannelNumber), uses frequency range (Band Class).
| Message parameter | Describe |
| Message Type | Type of message, for Handoff Performed message, its type is 17H (being that Message Type is fixed value 17H).Mandatory parameter. |
| Cause | Point out the reason of soft handover.1BH---Inter-BS soft handoff drop target 1DH---Intra-BS soft handoff drop target mandatory parameter. |
| Cell Identifier List | Description sees the following form.Mandatory parameter. |
| Channel Number | The channel number optional parameters. |
| Band Class | Use frequency range.Only between taking place frequently, during direct-cut operation, just can need to report this parameter.Optional parameters. |
Table 1
Wherein, the Cell Identifier List in this message is the array of cell identifier (Cell Id), is the Active Set cell list of current phone, and it points out that there is Radio Link current phone and which sub-district.Table 2 is the structure of Cell Identifier List.As shown in table 2, Cell Identifier List comprises cell identifier list sign, cell identifier description (Cell Identification Discriminator), Cell ID.

Table 2
As can be seen from Table 2, Cell ID has two kinds of method for expressing, and is indicated by Cell IdentificationDiscriminator.If Discriminator=02H, Cell ID comprises Cell and Sector; If Discriminator=07H, Cell ID comprises MSCID, Cell and Sector.If the sub-district belongs to source BS, can type of service 02H or the Cell ID of 07H; Belong to purpose BS as if the sub-district, then the Cell ID of necessary type of service 07H.And for different MSC, its MSCID is different.Therefore, according to above explanation, and referring to shown in Figure 4, it is as follows that system judges whether to take place between MSC the detailed process of soft handover:
Step 401, judge whether the Discriminator in the Handoff Performed message is 07H, if not, the sub-district that does not have purpose BS among the Cell Identifier List then is described, therefore there is not soft handover between BS, execution in step 402 then; Otherwise, execution in step 403;
Step 402, get first Cell ID among the Cell Identifier List;
Step 403, get first Cell ID among the Cell Identifier List;
Step 404, judge whether the MSCID among the Cell ID is identical with the MSCID of this MSC, if identical, illustrate that this sub-district belongs to source MSC, mobile phone does not switch to purpose MSC fully, execution in step 407, otherwise, execution in step 405;
Step 405, judge whether in addition Cell ID,, get next Cell ID if having, execution in step 404, otherwise, execution in step 406;
Step 406, MSC provide in ticket and switch indication and switching time;
Step 407, MSC record this Cell ID in the ticket as Designated Cell.
As can be seen, as long as have the MSCID of a Cell ID identical with the MSCID of this MSC among the Cell Identifier List, show that then mobile phone has Radio Link in the MSC of source from said process, at this moment, mobile phone does not switch to the BS under the purpose MSC fully; If the MSCID of all Cell ID is different with the MSCID of this MSC, show that then all Radio Links of mobile phone are based upon among the purpose BS of another MSC, mobile phone switches to purpose BS fully, at this moment, indicates in ticket and has taken place soft handover and time between MSC.
The charging center is as follows according to the processing procedure of ticket:
If the charging center has been roamed soft handover and chargeed, then should stop the soft handover roam charge.
This method judges at an easy rate whether mobile phone the soft handover roaming takes place in communication process, and this roaming is chargeed, for operator brings rational economic well-being of workers and staff.This method drops to minimum to the software modification amount of MSC, do not need to revise BS and MS.
Below again for embodiment two explanations technical scheme of the present invention.
This programme is to judge by source BSC whether mobile phone switches to purpose BS fully, with the MSCID of MSC under judged result and the purpose BS mode notification source MSC with message, MSC increases corresponding information according to the indication of message in ticket, by the charging center judgement whether the soft handover roaming takes place at last, and roaming is chargeed to soft handover.
So, judgement, executor as soft handover, source BS knows that by the resource management module of inside the situation of the subdistrict position of mobile phone and wireless channel knows that it still is purpose BS that the branch of the type of current soft handover and increase, deletion belongs to source BS, and source BS can judge whether mobile phone switches to purpose BS fully.Therefore, present embodiment is to notify MSC by newly-increased message that switches to purpose BS fully on the A1/A2 interface, i.e. Inter-MSC Handoff Notation message, and this message does not need response.
The structure of Inter-MSC Handoff Notation message parameter is as shown in table 3.Inter-MSCHandoff Notation message parameter comprises soft handover indication (Inter-MSC Handoff Indicator) between Message Type, MSC.Wherein, Inter-MSC Handoff Indicator indication mobile phone is to move to purpose BS fully, still gets back to fully in the BS of source, if switch to fully among the purpose BS, this message then further comprises MSCID, points out the MSCID of the MSC that purpose BS is affiliated.
| Message parameter | Describe |
| Message Type | Type of message, for Roam Notation message, its type is 70H (being that Message Type is a fixed value 70H) mandatory parameter. |
| Inter-MSC Handoff Indicator | The indication mobile phone is to move to purpose BS fully, still gets back to fully in the BS of source (purpose BS, source BS belong to different MSC).1---mobile phone has moved to (being position 3) 0 in the purpose BS fully---got back in the BS of source (being position 1) by mobile phone fully |
| MSCID | Only when Inter-MSC Handoff Indicator=1, just need this parameter, point out the MSCID of the MSC that purpose BS is affiliated |
Table 3
If mobile phone switches in the purpose BS fully, then source BS is after carrying out soft handoff procedure, send an Inter-MSC Handoff Notation message to source MSC, Inter-MSC HandoffIndicator be set in message be 1 and purpose BS under the MSCID of MSC; Otherwise, sending Inter-MSC HandoffNotation message, it is 0 that Inter-MSC Handoff Indicator is set in message.Source MSC is increased to message parameter in the ticket after receiving Inter-MSC Handoff Notation message, still judges by the charging center whether mobile phone is roamed at last, thereby starts or stops the soft handover roam charge.
