Description
Technical field
The present invention relates to field of telecommunications, particularly when realizing on the mobile communications network, reduce the system and method for caller number of call attempts when the unreachable called phone of calling.
Background technology
At present moving communicating field, speech business is the most basic communication service, and along with the growth of telecommunication user number, the audio call amount is also progressively increasing, and following phenomenon therefore often occurs: when the calling called phone, called phone is busy, a moment later, it still is busy exhaling again; When the calling mobile phone, often run into the situation of called shutdown, so the caller meeting exhales repeatedly again, up to called start.The appearance of above-mentioned phenomenon not only produces a large amount of infecctive call, but also takies a large amount of mobile communications network resources the call time of waste caller, is due to the defective of mobile communications network.The inventor thinks by increase a user Ke Da automatic informing system on mobile communications network, this system can allow caller know, but when called receipt of call, can in time notify it to set up calls out, just can overcome the above-mentioned defective that exists in the present mobile communications network, save calling subscriber's call time, reduce invalid number of call attempts, save the mobile communications network resource, but do not have this system and solution in the prior art.
Summary of the invention
The object of the present invention is to provide when the unreachable called phone of calling the system and method that reduces the caller number of call attempts, so that " when the unreachable called phone of calling time reduce caller number of call attempts " business to be provided on the mobile communications network.In the present invention, " reducing the caller number of call attempts when the unreachable called phone of calling " business is called " energy-conservation calling " business.
Technical scheme of the present invention is:
When the unreachable called phone of calling, reduce the system of caller number of call attempts, it is characterized in that comprising:
Mobile communications network provides the network between the mobile communication equipment to connect;
Mobile services switching centre (MSC) is connected with mobile communications network, and signaling is provided, the exchange of speech channel, services such as route, and when the unreachable user of calling, can play in the unsuccessful prompt tone of calling to caller, add the method for operation information that the prompting caller reduces number of call attempts;
Short message service center (SMSC) is connected with mobile communications network, and the reception short message is provided, and the storage short message is transmitted services such as short message;
The mobile communication access device, (MSC) is connected with mobile services switching centre, and the access service of portable terminal is provided;
Energy-conservation calling device, be connected with mobile communications network, be a kind of telecommunication path equipment, be used to receive calling subscriber's calling log-on operation, in time obtain reachable state and the notification enrollment user who is registered number or be registered the user, wherein said log-on operation comprises that dialing " the voice access code+called phone number of energy-conservation calling device " calls out registration, or sends short messages to " the note access code+called phone number of energy-conservation calling device " and mode such as register;
Portable terminal is connected with the mobile communication access device, is used to make a call, and receipt of call receives short message, sends SMS message.
Wherein, preferably, inaccessible state is meant off-mode.
Wherein, preferably, inaccessible state is meant busy condition.
When the unreachable called phone of calling, reduce the system constituting method of caller number of call attempts, it is characterized in that:
Utilize mobile services switching centre (MSC), call out to the caller playing and calling in the prompt tone of unreachable called phone, add the method for operation information that the prompting caller reduces number of call attempts at it; This method of operation information is the prompt tone that comprises following content: if when called reaching, obtain announcement information, please call the voice access code+called number of energy-conservation calling device;
Utilize energy-conservation calling device, receive calling subscriber's calling log-on operation, in time obtain reachable state and the notification enrollment user who is registered number or be registered the user.
Described notice adopts short message way.
The unreachable called phone of described calling refers to, the called phone shutdown; The prompt tone that described adding prompting caller reduces the method for operation information of number of call attempts is: " user that you dial shuts down, if when called start apprise you of, the voice access code+called number that please call energy-conservation calling device is registered ".
The unreachable called phone of described calling refers to, and called phone is busy; The prompt tone that described adding prompting caller reduces the method for operation information of number of call attempts is: " user that you dial is just busy, calledly calls back to you when idle if notify, and the voice access code+called number that please call energy-conservation calling device is registered ".
When the unreachable called phone of calling, reduce the method for caller number of call attempts, it is characterized in that, may further comprise the steps:
Step 1: the calling subscriber calls out " the voice access code+called phone number of energy-conservation calling device ";
Step 2: after energy-conservation calling device receives described call information, the mode of pointing out described calling subscriber to select service announcements, and, detect or subscribe to the state of described called phone number to switching network according to described calling subscriber's selection;
Step 3:, carry out service announcements according to the pattern that described calling subscriber selects when energy-conservation calling device receives described called phone number when being in the information of reachable state.
Wherein, preferably, described service announcements pattern is by the short message notification caller.
Preferably, described service announcements pattern is called by short message notification.
Effect of the present invention is: in mobile communication process, when called unreachable (shutdown or busy), caller is by shirtsleeve operation, just can realize " but when called receipt of call; by the short message notification isotype, make caller and called between can in time set up calling ", thereby save calling subscriber's call time, reduce invalid number of call attempts, save the mobile communications network resource.
