Description

A method for realizing phone binding

technical field

The invention relates to a phone binding method based on a digital program-controlled switching system, in particular to a method for establishing phone binding between a phone user (either a wired user or a mobile user) and another phone user through a binding agent.

Background technique

In the communication industry, the competition is becoming more and more fierce, and the means of competition are not only price competition, but also service competition. Rich service functions can facilitate the work and life of users, improve the competitiveness of operators, and attract more users. Phone binding is a new service that has recently emerged.

In everyday life, people are often associated with multiple phones. For example, when working, use the unit phone to make contact; after get off work, use the home phone or mobile phone to make contact. If someone dials the home phone number during work, or if someone calls the unit phone number after get off work, they cannot be contacted. Previously, this requirement could be fulfilled by "forwarding on no answer" in the new service. For example, forward to phone B when registration A does not answer. But this method has the following disadvantages:

1: Phones A and B can only have one phone ringing at the same time. When user C calls A, A starts to ring. At this time, B picks up the phone and cannot talk to C. After the no-response time period, A stops ringing and B rings instead. If A picks up the phone at this time, he cannot talk to C.

2: Time is very important in today's fast-paced life. When user C calls A, the call will be forwarded to B only if A does not pick up the phone within 20 seconds (adjustable duration). Caller C may not be able to persist for such a long time and directly hangs up, which will cause economic or emotional losses to both parties.

It is in this situation that the phone binding service appears. Phone binding means that a phone user (either a wired user or a mobile user) can arbitrarily designate another phone as his bound phone. When a user calls in, the two phones will ring at the same time, and any one phone can enter the talking state when off-hook, and the other phone will stop ringing at this time. The bound phone can be a wired user, a GSM user, a CDMA user, or a PCS (Personal Communications System) user.

The phone binding service includes the phone companion service and the one-number dual-phone service currently on the market.

Contents of the invention

The purpose of the present invention is to provide a method for realizing phone binding, which can flexibly and reliably provide the phone binding function without affecting the original service of the phone.

To realize the present invention, at least one switching office in the program-controlled switching system needs to add a binding proxy software module. This module can be placed in the switch or on the server. This module has the following functions: it can receive the calling user or network The "call setup message" sent by the phone and respond to the message "the called user has started to remind", but does not answer the ring back tone for the calling party; can initiate a call to the two physical locations registered in the binding service of the phone, when the receiving After either party enters the ringing state, the original caller is given a ring back tone. After receiving an answer from either party, release the other party and connect the call. For the incoming trunk, add the phone binding attribute; if a trunk may contain a call for a bound user, set the phone binding flag of the trunk. In the digital program-controlled switching system, the phone binding attribute is added to the user. An authentication server module is added in the exchange with a binding agent software module, its function is to manage the data of the phone and its bound phone, it can set up a phone binding service flag for the phone, and activate or deactivate the phone binding Service flag bit, you can use or stop this service.

In the present invention, the specific process of realizing binding phone includes the following steps:

(1) Add a binding agent software module in at least one exchange; set up a phone binding service flag for the user phone on the authentication server;

(2) Fill in the binding number of the user's phone and the number analyzer of the binding phone on the authentication server, and activate the user's "telephone binding service activation flag";

(3) When the calling party calls the user, the call arrives at the switching office with the binding agent software module through the relay;

(4) The binding proxy simulates the behavior of the user to interact with the calling party, so that both parties enter the ringing state, but does not send a ringback tone to the calling party;

(5) The binding agent simultaneously initiates calls to the two physical locations of the called user and its binding user; when receiving any party entering the ringing state message, then answer the ringback tone to the original calling party;

(6) After receiving the response from either the called user or the bound user, the binding agent releases the other party, and then connects the calling party and the called party;

(7) The calling party and the called party talk.

In the above scheme, the step (4) may specifically be: after the binding agent receives the phone binding message sent by the calling module of the incoming trunk, obtains the corresponding call resource, and returns the message to the calling module of the incoming trunk , the latter sends SETUPEVENT again, and the binding agent returns ALERTINGEVENT, thereby moving into the ringing state, but the binding agent does not answer the ring tone resource for the caller, but receives the prompt tone. Among them, SETUP EVENT refers to a message when a call is established, which is sent by the calling user to the network and sent by the network to the called user to start the call. ALERTING EVENT refers to another message when the call is established, which is sent to the network by the called user, and then sent to the calling user by the network, to indicate that the called user has started to remind.

Step (5) may specifically be: the binding agent simulates the behavior of the incoming trunk caller at this time, interacts with the user and the called software module of the bound phone, and if the status of the other party can be connected, then send SETUPEVENT. After receiving the ALERTING EVENT from any party, you can listen to the ring back tone for the original caller A.

In the above solution, the user of the switching office without the binding agent module needs to modify the relay data in the gateway office, so that the call to the user reaches the switching office with the binding agent module.

The present invention provides a method for flexibly and reliably providing the phone binding function without affecting the original new services of the phone in the existing digital program-controlled switching system, that is, the ability of two phones to ring at the same time, any phone off-hook , the other phone will stop ringing. It solves the ringing delay of two phones in the call forwarding mode and the inconvenience caused by it.

Detailed ways

FIG. 1 is a schematic diagram of providing a phone binding function in an existing digital program-controlled switching system.

Suppose users D' and B' are on the 711 office and belong to fixed telephones. User B is in office 133 and is a mobile phone, user D is in office 456 and is a fixed phone. User B' is the bound phone of user B, and user D' is the bound phone of user D. The 456 office is a newly added exchange office that can provide the phone binding function.

In order to realize the binding telephone function, add the authentication server software module in 456 bureaus. Its function is: to manage the data of phones and their bound phones. In order to facilitate the activation and termination of the phone binding service, a "telephone binding service activation flag" can be added to the phone. If phone B needs to use the phone binding service, it needs to register the phone number and its bound phone B’ number in the authentication server first, which means that phone B has the authority to use the phone binding service. But it is also necessary to activate the "telephone binding service activation flag" to tell the switching system that user B needs to use this service. In the future, if user B wants to stop using the service, he only needs to activate the "activation flag of the phone binding service". The activation and deactivation instructions can be issued to the authentication server in the man-machine command maintenance console, or a specific number can be dialed in, and then the corresponding functions can be completed according to the voice prompt.

First consider a relatively simple situation: user A calls user D.

1: Configuration data: Check the phone binding flag in the relay settings from the telecommunications gateway office to the 456 office, and fill in the binding number D’ of user D and the number analyzer of D’ in the authentication server. And activate the "telephone binding service activation flag" of user D.

2: When the call initiated by A reaches the 456 office through the trunk, since the 456 office can provide the phone binding function, the incoming trunk software module judges that there is a relevant phone binding sign on the trunk, and then sends a message to the authentication server To authenticate the new service of the called number, if the called number D activates the "telephone binding service activation flag", there is no need to find the relay or the called party, and instead send a message to the binding agent; if the incoming If the trunk has not checked the phone binding function or the called party D has not activated the phone binding function, the calling party will follow the normal process to find the trunk or the called party.

After the binding agent receives the phone binding message sent by the calling module of the incoming trunk, it obtains the corresponding call resource and returns a message to the calling module of the incoming trunk, which then sends SETUPEVENT, and the binding agent returns ALERTINGEVENT, Therefore, it moves into the ringing state, but the binding agent does not answer the ring tone resource for the caller, but answers the prompt tone.

The binding agent then applies for the call data area, and initiates a call to the two subscriber lines of the one-number two-phone. That is, the binding agent initiates a call to the user D of the office and the 711 office D'. For the user registered in the trunk one-number dual-device service and another user number, it needs to go through number analysis first, the number analyzer of D is determined on the incoming trunk, and the number analyzer of D' is configured on the authentication server . If the analysis fails, no calls can be made for this physical location.

The binding agent simulates the behavior of the incoming trunk caller at this time, interacts with the called software modules of D and D', and if the state of the other party can be connected, then sends SETUPEVENT. After receiving the ALERTING EVENT from any party, you can listen to the ring back tone for the original caller A.

If the states of D and D' both can be switched on, they are both already in the ringing state. If either party goes off-hook, the binding agent will receive a STARTCONVEVENT message. At this time, the other party is released, and then a message is sent to the calling software module of the original incoming trunk to transfer the call. After the transfer is successful, the binding agent can release the resources occupied by this call, and the calling and called users are in the talking state. The STARTCONVEVENT here is a message when the call is established, which is sent by the called party to the calling party to indicate that the called party has begun to pick up the phone to answer.

For users in the switching office that has not implemented phone binding, in order to realize the function of phone binding, the relay data needs to be modified in the gateway office so that all calls sent to phones with "telephone binding service" will reach the 456 office.

User A calls user B, and user B is in the 711 office, which has not implemented the binding phone function, and user B' is user B's binding phone.

At this time, the gateway office can be connected to the switching office 456 that has realized the binding phone function, as shown in FIG. 1 . It is necessary to modify the trunk routing data of the gateway office so that all calls to B must reach office 456.

User A initiates a call to user B and reaches the gateway office through the relay route selection. Since the data of the gateway office has been modified, the call will reach office 456. The situation thereafter is similar to the situation where user A calls user D analyzed above.

Due to the use of the binding agent to process the binding of the phone, the impact of this function on the previous new services is reduced to the minimum. Referring to Fig. 1, taking user A calling user B as an example, if user B has the "forwarding on no answer service", when the forwarding occurs at 20S, the call to B' will not be affected. If B' and B are users of the same switching office, and a new business occurs in B', the call to B will not be affected.

The above method can realize the binding function of three or more telephones after simple expansion. For example, when phone A is bound to A1, A2, and A3, you can first configure the binding data of A, A1, A2, and A3 in the authentication server, and then initiate the binding of A, A1, A2, and A3 in the binding agent. The call will make multiple telephones ring at the same time, if any telephone is off-hook, the other telephones will stop ringing.

The above methods can also be used in services such as 'Wandering Home', 'Fixed Line Priority', and 'Fixed Line Roaming' that appear in the market. These functions can be realized by configuring the binding relationship and data between phone A and another phone in the authentication server first, and then initiating a call to a certain phone in the binding proxy based on these relationships and data.

Although the preferred embodiment of the present invention has been illustrated and described, it will be understood by those skilled in the art that various changes, modifications and equivalent substitutions of parts can be made without departing from the scope of the present invention. Therefore, the invention is not intended to be limited to the particular embodiments disclosed for carrying out this invention, but the invention includes all embodiments falling within the appended claims.
