FIG. 3 is a signaling flow chart of a method for implementing a short message forwarding service associated with a call forwarding service according to an embodiment of the present invention.

Detailed ways

As shown in FIG. 1 , Embodiment 1 of the present invention provides a system block diagram for implementing a short message forwarding service linked with a call forwarding service.

A system for realizing short message forwarding service linkage call forwarding service, said system is composed of several network management bureaus, home location register HLR, short message service center SMSC, signaling transfer node STP and mobile switching center connected to the communication signaling network Composed of MSC, short message transfer center system or short message service center DCS and short message gateway.

In addition, the system also includes a short message forwarding service linkage call forwarding service function module,

The short message forwarding service linked call forwarding service function module is used to receive a short message forwarding service registration message or a cancellation message, and the short message forwarding service registration or cancellation message comes from a user or an operator's account system instruction, and sends a message to the short message The transfer center system SMFCS or the short message service center DCS forwards the registration or cancellation message of the short message transfer service;

Obtain the calling number and the forwarding number according to the registration message or deregistration message of the short message forwarding service, and simulate the mobile switching center to initiate the activation or deactivation of the user call forwarding subscription message to the calling home location register.

Preferably, the short message transfer service linkage call transfer service function module is used as an independent system to establish a connection with the short message transfer center system or the short message service center DCS.

In another preferred solution, the function module of the short message forwarding service associated with the call forwarding service can also be set in the short message transfer center system or in the short message service center DCS.

The embodiment of the present invention provides a system for realizing short message transfer service linkage call transfer service, and through a short message transfer service linkage call transfer service function module, on the basis of the short message transfer center system, the short message transfer service linkage voice The function of call transfer service realizes the linkage of short message transfer and voice call transfer on the large-scale communication network without changing the existing voice call service, voice call transfer service and short message service process.

As shown in Figure 2, the embodiment of the present invention also provides a kind of method that realizes short message transfer service linkage call transfer service, and described method comprises the following steps:

S101. The short message forwarding service linkage call forwarding service function module receives the short message forwarding service registration or cancellation message, and the short message forwarding service registration or cancellation message comes from a user or operator's account system instruction;

S102. Forwarding the short message transfer service registration or cancellation message to the short message transfer center system SMFCS or the short message service center DCS;

S103. Decoding and obtaining the MSISDN number of the calling MSISDN number and the forwarding number in the user or operator's account system instruction from the registration or deregistration message of the short message transfer service;

S104. Through the number of the calling MSISDN, the simulated mobile switching center initiates a routing request message to the HLR to which the calling MSISDN belongs, receives the routing response message returned by the HLR to which the calling MSISDN belongs, and decodes to obtain the calling party corresponding to the calling MSISDN IMSI number;

S105. Using the calling IMSI number, the simulated mobile terminal user and the mobile switching center send an activation or deactivation call forwarding service subscription message to the calling home location register.

As shown in FIG. 3 , it is a signaling flowchart of a method for realizing the linkage of the short message forwarding service with the call forwarding service. When the user registers the short message forwarding service, the short message forwarding service linkage call forwarding service function module detects the user's MSISDN, and simulates sending an SRI_FSM message to the HLR to which the user belongs to obtain the user's IMSI, and then simulates the user sending the call to the user's HLR A REGISTER_SS message is sent, and the supplementary service type carried in the message is call forwarding.

Wherein, according to the short message forwarding service type registered by the user, the corresponding call forwarding type may be: unconditional call forwarding or unreachable call forwarding.

The embodiment of the present invention provides a method for realizing the linkage of short message forwarding service with call forwarding service, on the basis of the short message forwarding center system, realizes the function of linkage of short message forwarding service with voice call forwarding service, so that on a large-scale communication network, in the Under the premise of not changing the existing voice call service, voice call transfer service and short message service flow, the linkage of short message transfer and voice call transfer is realized.

Those skilled in the art should realize that the above-mentioned specific embodiments are only exemplary, and are intended to enable those skilled in the art to better understand the content of this patent, and should not be construed as limiting the scope of protection of this patent. Any equivalent changes or modifications made to the spirit disclosed in the patent fall within the protection scope of this patent.
