detailed description

Referring to FIG. 1 , the existing CDMA network mainly includes the following network entities: BTS (Base Transceiver Station), BSC (Base Station Controller), and MSC (Mobile Switch Center, Mobile Switching Center). ), MC (Message Center, Short Message Center) and HLR (Home Location Register). The BTS is configured to transmit and receive wireless signals; the BSC is used for wireless channel management, implementing call and communication link establishment and teardown, and controlling handover of mobile stations in the control area; the MSC It is used for communication control and management of mobile users located in the control area of the MSC. The functions of the MSC are separated into two entities: MSCe (Mobile Switching Center Emulation) and MGW (Media Gateway). Call service control and media stream exchange are respectively performed; the MC is used to implement short message submission, storage and forwarding; and the HLRA is used to store a database of visited user location information.

In the system embodiment of the present invention, the HLR and the MSCe are included, where the HLR is used to store the calling party's fully paid service signed by the calling user; When the calling party of the caller's fully-paid service initiates the call, the calling MSCe transmits the subscription information of the calling party in the calling HLR to the called MSCe, and the called MSCe sends the assignment request message to the called user. Pass the call.

Referring to FIG. 2, the specific embodiment of the method for implementing the calling full payment service of the present invention is implemented based on the TIA EIA-41-D protocol, and includes the following steps:

Step 1. The calling user signs the MTFPH (Mobile Terminated FreePhone) in the HLR. At the same time of signing the service, the FPH number corresponding to the user can be set in the HLR to request the process in the subsequent location. This number is passed to MSCe for the calling number display.

Step 2: The calling MSCe transmits the subscription information of the calling party in the HLR to the called MSCe. Step 3: The called MSCe notifies the called user that the current call is completely paid by the calling user. Step 4: After the call ends, the calling party MSCe The calling party fully-paid service identifier is displayed on the calling CDR according to the calling party's fully-paid subscription information, and the called MSCe displays the calling full-paid service identifier in the called CDR according to the calling party's subscription information transmitted by the calling MSCe.

The signing process in step 1 can be extended by CFI ( Calling Feature

The indicator, the call feature indication, is implemented by a reserved bit in the parameter, and the extended reserved bit is used to identify the calling full payment service.

The CFI parameters are defined as follows:

The meanings of the above CFI parameter definition tables and contents refer to 6.5.2.20 of the TIA/EIA-41-D protocol. Call Feature Indicator (CFI, Cal l ingFeaturesIndicator) section. This embodiment utilizes the reserved bits in the above table, that is, the 4th byte H and G of the extended CFI Content (Contents) part, the two reserved bi t bits, to indicate the Calling Full Payment Service (MTFPH) subscription. Specifically: Bit (Bits) HG Value (Value) Meaning (Meaning)

0 0 0 not used

0 1 1 not signed

1 0 2 Signing is not activated

1 1 3 Sign up and activate

Step 2 is to add and transmit CFI parameters in the LOCREQ (Location Request), ROUTREQ (Routing Request) message flow by extending the related ANSI 41 message interface.

Since the called MSCe already knows that the call is fully paid for the call in step 2, in step 3, the called MSCe carries the self-constructed Display Text text content, indicating the present when the assignment request message is sent to the called user. The secondary call is fully paid for the calling party.

Referring to FIG. 3, another process of calling the full payment service embodiment of the present invention is: a. signing a calling party with a calling full payment service to initiate a call;

b. The calling MSCe sends LOCREQ to the called home HLRJ, with the CFI parameters of the calling user (including the caller's full payment service subscription information);

c called the home HLR through the ROUTREQ message to pass the CFI parameters (including the caller fully paid service subscription information) to the called MSCe;

d. The called MSCe returns the assigned TLDN (Temporary Local Directory Number);

e. Pass the called TLDN to the calling party;

f. The call is sent out to the called MSCe according to the TLDN;

g. When the called MSCe sends the assignment request message to the called user, it carries the content of the self-constructed display text Display Text, indicating that the call is completely paid for the call.

h. As with the normal call flow, the call is normally connected.

After the call ends, the calling MSCe displays the calling full payment service identifier in the calling CDR according to the calling full payment intelligent service key parameter, and the called MSCe transmits the primary message according to the calling MSCe. The called subscription information displays the calling full payment service identifier in the called bill.

Based on the above embodiment, the caller fully paid service can be further combined with the FPH service.

That is, in the previous LOCREQ process, the FPH number corresponding to the calling user can be returned by the calling party or the HLR, and the original calling number is overwritten by the number and displayed as the calling number to the called user, so that the customer can directly call back. Use our FPH business.

The delivery of the contract information of this service is not limited to the foregoing description, and may be completed by other methods. For example, from the perspective of parameters, the calling information of the calling party can be implemented without the CFI parameter (only the CFI parameter is original, and only the reserved bit can be extended), or a new parameter can be added to indicate the main Called the contractor to fully pay for the service. In addition, from the process point of view, the calling party's subscription information can also be passed to the called MSCe through the LOCREQ and ROUTREQ processes, and passed to the called MSCe through the call setup message, except that the former is modified by C. The /D port protocol is used to implement the latter. The latter is to modify the No. 7 signaling. Generally speaking, the former changes are easier.

It can be seen from the above embodiment that: through the full payment of the calling party, the enthusiasm and communication effect of the customer can be improved; Moreover, the use of the caller's fully paid service and the FPH service can make the customer have no need to consider the call cost when communicating with the company. , to maximize customer and company communication. In addition, from the perspective of the operator, the operator adopts the caller's full payment service of the present invention to further meet the communication needs of each company and the customer, and is beneficial to improving user satisfaction.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modifications, equivalents, improvements, etc., which are made within the spirit and principles of the present invention, should be included. It is within the scope of the invention.
