Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a system and a method for realizing cross-protocol voice-to-fax conversion in a mobile communication system.
Background
A CDMA (Code Division Multiple Access)2000 system provides not only a voice service but also a facsimile service. With the wide popularization and application of the CDMA2000 system, the basic voice service or fax service cannot meet the user's requirement, so the CDMA2000 system needs to provide the voice to fax service, that is, the user can send a fax through simple and convenient operation in the voice call process without performing fax dialing again.
For the voice to fax service, the ms (mobile Station) needs to complete the transition from the voice service to the fax service through the air interface service negotiation with the BSC (Base Station Controller). For example, in the voice call process, if a party of the voice calling party and the called party wants to receive a fax, the receiving end user presses a start key on the fax to initiate a voice-to-fax conversion, or the sending end user presses a key first, which is illustrated for clarity in the following description. After the mobile terminal of the fax receiving end detects the fax sound after the key is pressed, the fax service negotiation of the empty port of the fax receiving end is initiated.
On the other hand, the fax receiving end BSC indicates the base station controller BSC of the fax transmitting end to start voice to fax conversion through the exchange side, and after receiving the indication, the base station controller BSC of the fax transmitting end initiates fax service negotiation of the empty port of the fax transmitting end. After the negotiation between the MS at both ends and the BSC at each end is passed, the voice service can be successfully transferred to the fax service.
Basic fax services are divided into analog fax services and digital fax services, which implement different fax protocols, and use different wireless configurations such as fax SO (Service Option), for example, analog fax SO is 20, 21, and digital fax SO is 4101, 13. The cross-protocol voice-to-fax means that both fax parties support analog fax and digital fax. At this time, the success rate is very low when the voice is converted into fax.
As mentioned above, when the base station controller BSC at the fax sending end initiates the fax service negotiation for voice-to-fax transmission, if the fax protocol supported by the mobile terminal MS at the fax sending end is unknown, the wireless configuration used for initiating the fax service negotiation with the MS is determined by the BSC, the fax wireless configuration at the receiving end is probably used, if the fax protocols realized by the MS at the two ends are not consistent at the moment, the MS at the sending end does not support the wireless configuration carried in the negotiation request message of the BSC at the local end, the service negotiation is not accepted, the negotiation result returned to the BSC is either directly rejected or not a fax configuration even if a new wireless configuration is proposed, since the voice call is in progress and no indication of fax forwarding is obtained, the proposed new configuration or the wireless configuration of voice eventually fails negotiation, resulting in failure of voice fax forwarding.
In addition, for the non-cross-protocol voice-to-fax conversion, or when initiating the negotiation with the fax sending end MS, the fax sending end BSC determines in other ways without using the fax wireless configuration of the receiving end, and at this time, the possibility of the negotiation failure still exists under the condition that the fax protocol implemented by the sending end MS is unclear. Thus, there is a significant risk of such negotiations and the rate of voice to fax failures can be high.
In summary, in a mobile communication system supporting a multi-protocol fax service, how to avoid the problems of inaccurate negotiation and high failure rate during cross-protocol switching when a voice fax is implemented becomes a technical problem to be solved.

The first mobile terminal initiates fax service negotiation to the first base station controller by wireless configuration supporting fax protocol.
When the second base station controller and the second mobile terminal initiate the fax service negotiation, it selects one fax service negotiation from the multiple fax protocols supported by the second base station controller to initiate the fax service negotiation to the second mobile terminal: if the wireless configuration of the selected fax protocol is consistent with the wireless configuration of the fax protocol supported by the second mobile terminal, switching to the fax service after the negotiation is finished; otherwise, selecting one from the rest fax protocols to continue negotiation with the second mobile terminal, and so on until the negotiation is successful, and switching to the fax service according to the fax protocol which is agreed by the two parties.

202. after detecting fax sound in the voice call process, the MS obtains a voice-to-fax instruction, sends a fax service request message to the home terminal BSC, and proposes a new fax service configuration (including SO corresponding to an MS fax protocol, and the like);
203. after receiving the fax service request message, the BSC obtains a voice-to-fax indication, sends a switching indication message to the MS, and guides the MS to switch from the current voice service to the fax service;
204. after receiving the switching indication message, the MS starts to switch from the voice service to the fax service and sends a switching completion message to the BSC after completing the switching;
205. after receiving the switching completion message, the BSC sends a service connection message to the MS, which indicates that the BSC agrees to new fax service configuration and simultaneously indicates the MS to start using the new fax service configuration;
206. after receiving the service connection message, the MS sends a service connection completion message to the BSC, and informs the BSC that new fax service configuration is started to be used, and the process is finished.
