Description

A cell billing method, system and device

technical field

The present invention relates to the field of communication technology, in particular to a cell charging method, system and equipment.

Background technique

In order to encourage mobile users to use mobile phones instead of fixed phones at home, many mobile operators have launched HomeZone services. The HomeZone service is to sign a list for the user. When the user initiates a call or forwards the call in this type of cell, the preferential rate is implemented. It is a custom-made service based on location information.

Regarding the location change event processing method under the preferential cell, the commonly used CAMEL (CustomizedApplications for Mobile network Enhanced Logic, customized application of mobile network enhanced logic) 1/2/3 protocol only supports the IDP (Initial detection point, start the detection point) ) message to the SCP (Service Control Point, Service Control Point) to deliver the user's location information (LocationInformation, including cell and location area and VLRID).

In the prior art, there are billing preferential services based on location information, such as HomeZOne. At present, the industry has both intelligent and non-intelligent implementation solutions for the HomeZone service.

Existing technology 1: intelligent implementation scheme, the preferential cell list of each user is stored on the SCP. The SCP extracts the cell information in the IDP message reported by the SSP (Service Switching Point, Service Switching Point), compares the user's subscription preferential cell list to determine the rate of the call, and the final rate is inserted into the MSC by sending the FCI message Single. The billing center finally deducts fees according to the FCI information in the MSC bill.

In the process of realizing the present invention, the inventor finds that there is the following shortcoming in the prior art:

The current intelligent solutions are all based on CAMEL1/2/3, and these standard protocols do not support real-time reporting of location change information during calls to SCP. Therefore, it is impossible to adjust the rate in real time by detecting the change of the user's location, and it does not support the adjustment of the rate when the user switches between systems.

As a result, the rate can only be determined when the call is initiated, and subsequent users cannot enjoy the preferential rate when they move to a non-preferential cell or move from a non-preferential cell to a preferential cell.

Moreover, in the current intelligent scheme, the SCP cannot obtain the inter-system switching of the call and the switching information between the MSC (Mobile Switching Center, Mobile Switching Center), and cannot respond accordingly.

Prior Art 2: non-intelligent implementation scheme, the user's preferential cell list is generally signed in the HLR (Home Location Register, home location register). It is common to sign a ZoneCode list for the user, and MSC binds one or more cells for each ZoneCode and defines a rate code. When a call is initiated or forwarded late, the MSC checks whether the cell of the current user appears in its ZoneCode list, and if so, puts a special mark in the bill and fills in the rate code corresponding to the ZoneCode. The billing center finally executes deduction according to the rate code in the MSC bill.

In the process of realizing the present invention, the inventor found that the second prior art also has the following disadvantages:

The rate adjustment of the non-intelligent implementation scheme is carried out offline, so it is impossible to realize the real-time notification to the user when the rate changes. The user experience is not good. On the other hand, the user subscription method of the non-intelligent implementation scheme is not standard, especially the implementation scheme using ZoneCode may conflict with the roaming restriction service based on ZoneCode, which is not conducive to the promotion of the scheme.

Detailed ways

The embodiments of the present invention will be further described below in conjunction with the drawings and examples.

Embodiment 1 of the present invention provides a preferential cell charging method, as shown in Figure 1, comprising the following steps:

Step S101, the MSC/SSP triggers the preferential cell charging service when the MS initiates a call or the called party makes a late forwarding, and the MS is an MS that has signed the preferential cell charging service based on the customized application CAMEL4 protocol based on mobile network enhancement logic .

Step S102: MSC/SSP receives the location change event information list issued by the SCP according to the preferential cell charging service, monitors the location change event information in the MS cell handover in real time, and reports the location change event information to the SCP .

After the above steps, it also includes: the MSC/SSP receives the cell charge rate information sent by the SCP according to the location change event information, and sends the charge rate information in the cell handover to the MS. Try to ensure that the rate information is sent in real time, but it can also be set reasonably according to the system performance. Real-time transmission is not required, but it does not affect the realization of the service. However, the real-time transmission of the rate information during the switching process is guaranteed, and the user experience is better. If the MSC/SSP allows it, the SCP can also send the location change information list and rate information to the MSC/SSP together. Usually the former is the preferred method, because each equipment has a reasonable division of labor and is easier to implement on an existing basis.

At the same time, in the above steps, it also includes MS and SCP signing a preferential cell charging service based on the CAMEL4 protocol; at the same time, on the basis of signing with the SCP, the MS can also sign a preferential cell charging service with the MSC/SSP, which can be used for Set the way to send the charging rate information during the switching process to the mobile station, for example: send the charging rate information during the call to the mobile station regularly, or only send the charging rate information once when staying in the same cell during the cell switching process rate information, and display the rate information of the cell to which it belongs when it is turned on.

In this embodiment, the MSC/SSP also includes creating a bill during the information exchange process, and the bill includes at least the location change event information and the switching time stamp reported by the MSC/SSP to the SCP. And when the location change event information exchanged between the MSC/SSP and the SCP is correlated with the charging rate information, the bill further includes the charging rate information issued by the SCP. The MSC/SSP transmits the bill file to the mobile billing center, and the mobile billing center directly deducts charges according to the location change event information, switching time stamp, and the rate information. On the other hand, the location change event information and the rate information may not be associated, and the rate information is not filled in the bill, and the MSC/SSP transmits the bill file to the mobile billing center to process the service When the offline bill of the mobile billing center is used, the mobile billing center queries the user database of the SCP in real time to obtain the charging rate information of the MS in different preferential cells, and proceeds according to the location change event information of the bill file and the charging rate information. Deduction. Through the above deduction method, the rate information sent to the MS, the rate information in the bill, and the rate information in the SCP user database are consistent with the rate information deducted by the BC.

The correlation between the location change event information and the tariff information is realized by extending the private object of the location change criterion. The private object of the extended location change criterion specifically includes: the MSC/SSP and the SCP add a location change charging area ChargeAreaCode attribute in the location change criterion; and the MSC/SSP matches the SCP described above Assign a location change sequence ChangOfLocationCounter identifier to the location change sequence after the location change criterion.

When the location change event information and the charging rate information may not be associated, when the cell charging rate information in the preferential cell charging service signed by the MS is adjusted, the charging rate information is stored in the or the old cell rate information or the latest rate information is selected according to the generation time of the offline bill.

Embodiment 2 of the present invention provides an enhanced preferential cell charging method. Embodiment 1 is applied to a specific scenario, as shown in FIG. 2 , including the following steps:

Step S201, MS signs CAMEL4 preferential cell/common preferential cell intelligent service (OCSI/DCSI); and customizes the list of preferential cells (2G and 3G)/location areas to which the MS belongs and corresponding tariffs in SCP.

In this step, the CAMEL4 protocol provides a location change event reporting mechanism, which allows the SSP to report the switching behavior of the user to the SCP in real time during the call process. This reporting is conditional. SSP needs to implement certain guidelines. The guidelines defined in the standard protocol (29.078650) are:

1. Entering or leaving a 2G (The Second Generation, second-generation mobile communication technology) cell (enteringCellGlobalId/leavingCellGlobalId);

2. Entering or leaving a 3G (The Third Generation, third-generation mobile communication technology) cell (enteringServiceAreaId/leavingServiceAreaId);

3. Entering or leaving a location area (enteringLocationAreaId/leavingLocationAreaId);

4. Switch from GSM (Global System for Mobile Communications, Global System for Mobile Communications) to UMTS (Universal Mobile Telecommunication System, Universal Wireless Communications System) (inter-SystemHandOverToUMTS);

5. Switch from UMTS to GSM (inter-SystemHandOverToGSM);

6. Inter-PLMN Handover (inter-PLMNHandOver) occurs between PLMN (Public Land Mobile Network, land public mobile network);

7. Switching (inter-MSCHandOver) within MSC (Mobile Switching Center, Mobile Switching Center) occurs.

The above criteria can be mixed and customized, and a user supports up to 10 criteria, that is, only a maximum of 10 cells/location areas (also called location change criteria information) can be supported in the preferential cell list and location area list signed by each user.

Step S202, when the MS initiates a call or as the called party, the MSC/SSP triggers the preferential cell intelligent service subscribed by the MS.

Step S203, the SCP sends the MSC/SSP a list of cells/location areas with preferential rates corresponding to the MS (the MS that triggers the smart service) to the MSC/SSP during the RRBE operation, and requires the MSC to monitor the cell information changes of the MS during the call .

Step S204, the SCP indicates that the call can continue.

Step S205, the MS is switched during the call, if the call is switched between the preferential cell/location area and the non-preferential cell/location area, the MSC/SSP reports the location change ERB (Event ReportBCSM, basic call state model event report) event.

Step S206, the SCP sends SCI (Send Charging Information, charging sending message) (SSP is converted into AOC (Advice Of Charge, charging notification)) or plays a Tone tone to notify MS that the charging rate is switched.

In step S207, the MS can know the rate change during its communication in real time. and react.

Step S208, the MSC transmits the bill file to the mobile billing center BC, and the BC obtains the bill; inquires about the location information, time information and the rate information of the cell in the bill; The location information, time information and the rate information of the cell are deducted from the conversation fee.

According to the standard protocol, the preferential cell list and location area list signed by each MS can only support up to 10 cells/location areas (also called location change criterion information). In order to provide greater flexibility, the concept of charging area is introduced between SSP and SCP: ChargeAreaCode. A charging area consists of several connected cells. The operator divides the entire network into multiple charging areas according to operational needs, and assigns a unique ChargeAreaCode to each charging area. The understanding of the mapping relationship between the ChargeAreaCode and the cell needs to be consistent between the MSC and the SCP. End customers enjoy preferential rates through the signing offer ChargeAreaCode. The billing area can be large or small, depending on the needs of the operator.

It is also possible to support more preferential cells/location areas by modifying the numOfChangeOfPositionControlInfo constant defined in the 29.078 protocol.

By signing a preferential cell, a preferential location area and a preferential charging area at the same time, this embodiment can customize charging preferential areas of different granularities for the MS to the greatest extent.

The operator can also choose to report a location change event when a handover between 2G/3G systems and between MSCs occurs. When this switching occurs, the terminal MS can enjoy the real-time rate change notification.

In order to avoid frequent cell switching by mobile stations in busy areas with dense preferential cells, resulting in frequent reporting of location change events by MSC/SSP, and thus overloading the service processing capacity of the system, MSC/SSP needs to provide a sampling protection mechanism, which can be based on service Flexible configuration of processing power. For example: the time interval between two consecutive reports cannot be less than 10 seconds. Generally, the shorter the reporting interval, the more accurate the billing and the better the user experience.

The location change information reported to the SCP must be recorded in the MSC bill. The ChangeOfLocation information sent by the SCP in the RRBE is also recorded in the MSC bill. At the same time, the MSC bill also records the tariff ( extracted from the corresponding SCI).

The billing center collects the bills of the MSC, and decides billing based on the switching information, ChangeOfLocation information, and tariff information therein.

In order to ensure that the tariff information notified by the SCP to the terminal MS in real time can be accurately recorded in the bill for offline deduction, it is necessary to associate the SCI with the ERB. This association can be achieved by passing the extended ChangeOfLocationCounter parameter:

MSC/SSP allocates a ChangeOfLocationCounter (unique within this call) for this location change sequence after matching the location change criteria. The SSP carries the ChangeOfLocationCounter in the reported ERB (oChangeOfPositionSpecificInfo/tChangeOfPositionSpecificInfo).

After the SCP judges the rate discount, it issues the SCI, which carries the AOC parameters (including the new rate) and returns it to ChangeOfLocationCounter.

The MSC/SSP correlates the received SCI with the handover event on the network side according to the ChangeOfLocationCounter. The MSC records the handover time stamp, handover location change information and the new rate determined by the SCP in the bill.

This scheme has the following three situations for the private extension of the 29.078650 protocol, wherein the parts in bold and italics are the objects to be expanded in this embodiment (including: charging area, ChargeAreaCode; and location change sequence, ChangeOfLocaionCounter):

In the process of defining the above-mentioned information elements (such as: ChangeOfLocationCounter), including but not limited to the above-mentioned expressions, the method of realizing cell charging through the association of such information elements belongs to the technical scope of the protection of the present invention, and does not Let me repeat.

The above-mentioned embodiment 1 and embodiment 2 provide a solution through SCI/ERB association, SCP determines the rate, and fills it in the bill, and the billing center directly handles it. The SCP prompts the cost information to the terminal MS in real time through the AOC message. When the Billing Center processes offline bills, it also needs to determine different rates for different MSs based on the location information. How to ensure the cost between the SCP and the billing center for the same call? rate synchronization.

Embodiment 3 of the present invention provides a cell billing method. Embodiment 1 is also applied to a specific scenario. The difference from Embodiment 2 is that SCI/ERB is not associated, and charging information is not filled in the bill. When processing the offline bill of the service, the billing center queries the user database of the SCP in real time to obtain the charging rates of the MS in different preferential cells.

The specific steps are as follows (figure omitted):

Step S301, MS signs CAMEL4 preferential cell/public preferential cell intelligent service (OCSI/DCSI); and customizes the list of preferential cells (2G and 3G)/location areas to which the MS belongs and corresponding tariffs in SCP.

Step S302, when the MS initiates a call or as the called party, the MSC/SSP triggers the preferential cell intelligent service subscribed by the MS.

Step S303, the SCP sends the MSC/SSP a list of cells/location areas with preferential rates corresponding to the MS (the MS that triggers the smart service) to the MSC/SSP during the RRBE operation, and requires the MSC to monitor the cell information changes of the MS during the call .

Step S304, the SCP indicates that the call can continue.

Step S305, the MS is switched during the call, if the call is switched between the preferential cell/location area and the non-preferential cell/location area, the MSC/SSP reports the location change ERB (Event ReportBCSM, basic call state model event report) event.

In step S306, the SCP issues the SCI (SSP is converted to AOC) or plays a tone to notify the MS that the charging rate is switched through the MSC/SSP.

In step S307, the MS can know the rate change during its communication in real time. and react.

Step S308, MSC transmits the bill file to the mobile billing center BC, and BC obtains the bill; according to the location information and time information in the bill, the real-time query obtains the charging rate of the MS in different preferential cells; according to the bill The conversation fee is deducted from the bill and the rate information in the user database of the SCP.

The triggering, sampling and reporting of location change event information during cell handover are similar to the second embodiment. Since SCI/ERB is not associated, there is no rate information filled in the call bill. In order to ensure that for the same call, the SCP rate information is synchronized with the billing center’s offline call bill for deduction. The adjustments are as follows :

Adjustment 1. The modification of SCP to MS preferential cell subscription information will only take effect in the next call. And the SCP continues to retain the data before modification. (The retention period is not less than the deduction processing period of the offline bill)

Adjustment 2. When the billing center queries MS’s preferential cell subscription information, it carries the generation time of the offline bill, and the SCP decides whether to return the old preferential cell subscription information or the latest preferential cell subscription information according to the time stamp of the location change event information.

Through the above adjustments, when the subscription information of preferential cells in the SCP (correspondence relationship between tariffs and preferential cells) changes, although the changes cannot be reflected in the offline bill in real time, the actual AOC and offline information of the MS can still be retained. The actual deduction of the bill is the same.
