CROSS-REFERENCE TO RELATED APPLICATION(S)
This application is the U.S. National Phase application of PCT application number PCT/CN2013/079034 having a PCT filing date of Jul. 9, 2013, which claims priority of Chinese patent application 201310033189.X filed on Jan. 29, 2013, the disclosures of which are hereby incorporated by reference.
TECHNICAL FIELD
The present document relates to the call transfer setting technology, and more particularly, to a call transfer setting method and system.
BACKGROUND OF THE RELATED ART
Mobile terminals (such as mobile phones, tablet PCs) are developing rapidly and applied universally, and they have become an everyday essential communication tool, but there are also specific requirements on timely processing calls and SMS, for example, many users always miss important calls or text messages because they forget to bring their phones or their phones are out of batteries, which at least brings inconvenience to life, and worst of all, the users may miss important business, emergency calls and so on.
The call transfer technology brings solutions to this situation, and to a certain extent, it can reduce missing calls. There are two traditional methods for setting and enabling the call transfer function:
the first method is setting in the local machine in advance and notifying the network side, and incoming calls are forwarded to a preset number when meeting the specific call transfer condition, but this method cannot enable the call transfer function in order not to miss important calls in the case that a user forgets to bring the mobile phone.
The other method is setting through an online business hall, and the call transfer function can be set after logging in. This method has requirements on network environments and also has limitations. Therefore traditionally, users cannot set and enable the business without the abovementioned objective conditions.

It should be understood that, the specific embodiments described herein are only used to explain rather than limit the present document.
First, in conjunction with FIG. 1 and FIG. 2, the method according to the embodiment of the present invention will be described in detail.
The first method of the embodiment:
As shown in FIG. 1, FIG. 1 is a schematic diagram of the process of the first method in accordance with an embodiment of the present invention, and the method may comprise the following steps:
in step 101: two terminals pre-established a pairing relationship through a network side;
in step 102: when one of the terminals enables the call transfer function according to the demand of the other terminal paired therewith, the terminal initiates an enabling call transfer request to the network side;
in step 103: the network side searches for the other terminal paired with the terminal according to the enabling call transfer request of the terminal, enables the call transfer function of the terminal and transfers all calls of the other terminal to the terminal.
The second method of the embodiment:
As shown in FIG. 2, FIG. 2 is a schematic diagram of the process of the second method according to the embodiment of the present invention, and the method may comprise the following steps:
in step 201: one of the two terminals (such as terminal A) initiates a matching request to the other terminal (such as terminal B) which it intends to be matched with, and carries an authentication password in the matching request;
in step 202: the terminal B performs a confirmation after receiving the matching request, if it does not agree, the terminal B replies the corresponding rejection information to the terminal A; if it agrees to establish a pairing relationship, it replies with information of agreeing to establish a pairing relationship, and it also carries an authentication password in the information and sends it to the terminal A;
in step 203: after receiving the information of agreeing to establish a pairing relationship sent by the terminal B, the terminal A compares the authentication password sent by the terminal B with the previously sent authentication password, and after confirming that there is no mistakes, it executes the step 204, meanwhile, it sends the confirmed correct information to the terminal B, and after receiving the message, the terminal B also executes the step 204;
in step 204: the terminal A or the terminal B report the pairing information along with the authentication password to the network side, such as an operator server;
in step 205: the network side matches the pairing information reported by the two terminals, and saves the pairing information and the authentication password after the matching is successful; wherein, the pairing information at least comprises information of the other terminal which establishes a matching relationship with the present terminal, for example, the pairing information reported by the terminal A records that the call transfer number of the present terminal is the terminal B, similarly, the pairing information reported by the terminal B records that the call transfer number of the present terminal is the terminal A, and the pairing information reported by the two terminals is mutual, meanwhile during the search, each terminal can take its own number as the keyword to search out the number of the other terminal paired therewith.
The above is the process of two terminals establishing a matching relationship, and the process is initiated by one terminal, and the pairing relationship of call transfer is established in the wireless way (including but not limited to the BT/WIFI/NFC), but in this case, the call transfer function is not enabled, and the user only presets the call transfer in advance, and after one terminal enables the call transfer function, all the calls (including calls and text messages and so on) are actually transferred according to the call transfer number.
In step 206: one terminal initiates an enabling call transfer function request including an authentication password; for example, the user of the terminal A left the terminal A at home, and the user notifies the terminal B to enable the call transfer function, and the terminal B sends an enabling call transfer function request;
in step 207: the network side receives the enabling call transfer function request sent by the terminal B, and from the saved pairing information of the terminal B, it searches out that the terminal paired therewith is the terminal A, and after successfully authenticating the authentication password of the terminal B, the network side enables the call transfer function of the terminal paired therewith, and transfers all incoming calls and messages of the terminal A to the terminal B.
In the above, the second method according to the embodiment of the present invention works as a preferred embodiment of the present invention, and an authentication password is set when a terminal interacts with a terminal and a terminal interacts with a network side, which is mainly considered from a security perspective, but those skilled in the art should know that the implementation of the embodiment of the present invention is not necessarily dependent on the authentication password, that is, setting the authentication password belongs to alternative technical means of the embodiment of the present invention.
In the following, the system embodiment of the present invention will be described in detail with reference to the accompanying figures.
As shown in FIG. 3, FIG. 3 is a schematic diagram of the structure of a system embodiment of the present invention, which specifically comprises: a network side, and two terminals which establish a pairing relationship via the network side,
when one of the terminals enables the call transfer function according to the demand of the other terminal paired therewith, the terminal is used to initiate an enabling call transfer request to the network side; the network side searches for the other terminal paired with the terminal according to the enabling call transfer request of the terminal, and enables the call transfer function of the other terminal, and all calls of the other terminal will be transferred to the terminal; when the terminal disables the call transfer function according to the demand of the other terminal paired therewith, the terminal sends a disabling call transfer request to the network side and requests the network side to disable the call transfer function of the other terminal, the network side disables the call transfer function of the other terminal according to the disabling call transfer request.
As a preferred system embodiment of the present invention, when one of the terminals initiates a pairing request to the other terminal which it intends to be paired with and is successfully authenticated with the other terminal, the terminal and the other terminal respectively request the network side to establish a pairing relationship with the peer party, and the network side establishes a pairing relationship of the two terminals after the terminal is successfully paired with the other terminal. Wherein, the terminal carries an authentication password at the same time of sending the matching request to the other terminal which the terminal intends to be paired with, and if the other terminal agrees to establish a pairing relationship, it replies an authentication password to the terminal, and when the terminal matches the received authentication password with authentication password sent by itself and the matching is confirmed to be successful, the terminal and the other terminal to be paired therewith are successfully authenticated; after the terminal and the other terminal to be paired therewith are authenticated successfully, the terminal and the other terminal respectively report their pairing information and authentication passwords to the network side and request the network side to establish a pairing relationship with the peer party; the network side matches the matching information and the authentication passwords received from the two terminals in order, and establishes a matching relationship of the two terminals after all the matchings are successful while saving the matching information and the authentication passwords. Therefore, if the terminal initiates a call transfer request to the network side and carries the authentication password, after the network side searches out the other terminal which is paired with the terminal according to previously stored matching information, and matches the authentication password in the transfer request with the previously stored authentication password, and after determining that the matching is successful, it enables the call transfer function of the other terminal, and transfers all the calls of the other terminal to the terminal.
The embodiment of the present invention further provides a terminal, comprising: a pairing module and a call transfer module, wherein:
the pairing module is configured to: establish a pairing relationship with a second terminal via the network side;
