Description

A method for realizing Speed key service in IP cluster network

technical field

The invention relates to the communication field, in particular to a method for realizing Speed key service in an IP cluster network.

Background technique

Private Branch (telephone) Exchange (PBX) is a dedicated telephone exchange widely used in commercial enterprises. It is connected to the exchange of the telecommunications provider through an E1 circuit or telephone line. Because it is a dedicated exchange, it can also provide special telephone services within the enterprise, among which the Speed Key service is a representative special service.

The Speed Key service is also called a push-to-talk service, that is, a service that can quickly enable various special services through a single key.

Speed Key mainly includes the following characteristic service businesses:

1) Status indicator function business

●There is an indicator light on the phone to indicate the status of other users, including busy (off-hook, talking), idle, ringing and hold, and other user status;

●Users can configure the different indicator lights on each phone;

●A user's status can be subscribed by multiple users;

● A user can subscribe to the status of multiple users.

2) The status indicator function can provide one-button quick operation of various value-added services.

The following are examples, but not limited to, these businesses:

A) One-click pickup

If the indicator light corresponding to a certain user on the phone indicates that the user is ringing, the user can pick up the call by pressing the button corresponding to the indicator light.

B) One-key hold and restore

If the user is in a call, you can put some calls on hold (Call Park) by pressing a button, and other phones that have subscribed to the user's status will display that the user is on hold, and then press the button corresponding to the indicator light on these phones Pick up the held call.

C) One-click call transfer

Call transfer means that user terminal A calls another user terminal B as the calling or called party. During the call, user terminal A can call another user terminal C by pressing the button corresponding to the idle state indicator light. At this time, user terminal B Listen to music and stay in the suspended state, then user terminal A hangs up, and user terminal C can talk to user terminal B after answering. Alternatively, user terminal A hangs up after talking with user terminal C, and user terminal C and user terminal B directly enter a talking state.

Existing Speed Key services are provided through PBX small switches. In the process of implementation, each business user needs to rent a dedicated line to connect to its own switch, and each enterprise must have dedicated switch maintenance personnel. Maintenance costs are high. However, in the process of realizing the Speed Key service, it is impossible to enjoy the rich and colorful characteristic services and powerful service support provided by professional telecom operators within the enterprise.

In order to expand their commercial space during the competition, professional telecom operators have developed trunking network services, which enable telecom operators to provide business users with services similar to private branch exchange (PBX).

The cluster network is a virtual private network (VPMN), which uses a public mobile communication network and an intelligent service platform to provide users with a logical network with the characteristics and functions of a private network. Its characteristics are: using the transmission and switching equipment of the mobile network to form a non-physical dedicated communication for a specific user group.

The IP trunking network service is based on the softswitch-based trunking network service. It is a service established on the IP network. Each user has its own number in the group and a long number outside the group. Users in the group can use the number to call each other. The user experience It's like using a private branch exchange (PBX).

However, none of the existing IP trunking networks supports Speed Key services, which hinders telecom operators from providing services to business users and expanding business space.

Contents of the invention

Detailed ways

In order to make the object, technical solution and beneficial effects of the present invention clearer, the method for realizing the Speed key service in the IP cluster network of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the specific embodiments described here are only for illustrating the present invention, rather than limiting the present invention.

The preferred embodiment of the present invention is especially aimed at the MGCP (Media Gateway Control Protocol, Media Gateway Control Protocol) telephone terminal in the IP trunking network, in order to realize the Speed key function and describe, but the present invention is equally applicable except the IP trunking network mentioned above Phone terminals other than MGCP phone terminals, such as SIP smart phone terminals, H323 smart phone terminals and H248 smart phone terminals.

Realize the Speed key function on the terminal, such as one-key quick operation services such as one-key pickup, hold and resume call, call transfer, etc. The principle of its realization is that the smart phone terminal simulates the user's operation process and realizes it based on the status display of the indicator light Therefore, as long as each terminal sets the corresponding relationship between the user terminal and the indicator light, and records the relationship in the media gateway controller connected to each terminal, the Speed key function can be realized in each user terminal of each IP cluster network.

In the embodiment of the present invention, for the MGCP phone, in order to realize the Speed key function, the MGCP protocol is extended.

The MGCP protocol is an existing technology. In the MGCP architecture, it mainly includes multiple media gateway controllers (Media Gateway Control, MGC, also called softswitch entities).

A media gateway controller (MGC) can manage multiple endpoints (Endpoints), that is, terminals. These terminals can be telephone sets, fax machines or a certain time slot (timeslot) in the E1 trunk.

Event and Signal are used for communication between the terminal and the media gateway controller. The message sent by the terminal to the media gateway controller is called Event, which mainly informs the media gateway controller of the current status of the terminal, such as: Off Hook, On Hook, DTMF Tone, Busy Tone, Ring Tone, etc. The message sent by the media gateway controller to the terminal is called Signal, which mainly requires the terminal to perform an operation. For example: Ring, Dial Tone, Call Waiting Tone, etc.

See RFC2705 Media Gateway Control Protocol for a detailed description of the specific technical solution of MGCP, which is quoted in its entirety in the present invention and will not be repeated one by one.

According to the description of the extension package in RFC2705, the extension package X-KS shown in Table 1 is newly added to realize the Speed Key feature. The extension package X-KS can exist in the RQNT message and the NTFY message. Among them, the message format in the extension package may not be case-sensitive.

The RQNT message is when a certain event occurs, the media gateway controller (MGC) notifies the terminal, and the parameter value includes Endpoint Id, Request Identifier, etc.

The NTFY message is used to inform the media gateway controller that an event has occurred at a certain terminal (Endpoint), and the parameter value is used to describe what event is.

The following describes in detail how the MGCP phone utilizes the MGCP protocol extension package X-KS to realize the Speed key function:

Step 1: The first terminal configures the second terminal corresponding to the indicator light, and uses the NTFY message to notify the media gateway controller of the corresponding relationship, the media gateway controller records the corresponding relationship, and sends the processing result to the first terminal after processing RQNT messages.

The first terminal may be an MGCP telephone user terminal, or an MGCP telecom operator terminal,

Step 11: first, the first terminal configures the second terminal number corresponding to the indicator light, and notifies the media gateway controller of the corresponding relationship through the NTFY message, and the media gateway controller records the corresponding relationship;

As shown in Figure 1, the first terminal can be configured with the second terminal number corresponding to a certain indicator light, and then the first terminal notifies the corresponding relationship of the second terminal number corresponding to the indicator light to the media gateway controller (softswitch gateway), which It can be realized through an NTFY message, which includes the modified indicator light number and the corresponding second terminal number, and the second terminal number can be empty, which is used to indicate that the second terminal number corresponding to the indicator light is deleted.

Preferably, only one record can be modified, added or deleted in one NTFY message.

For example:

111) The user number corresponding to the specified indicator light number 0 is 12345678, then:

NTFY 1 aaln/1@test.XXX.com

X: ffffffff

O: X-KS/lamp(0, 12345678)

112) Specify that the user number corresponding to indicator light 0 is 12345678, the user corresponding to indicator light 1 cancels the subscription relationship, and the user number corresponding to indicator light 2 is 56789:

NTFY 1 aaln/1@test.XXX.com

X: ffffffff

O: X-KS/lamp ((0, 12345678), (1, ), (2, 56789))

Step 12: As shown in FIG. 1 , the media gateway controller sends the RQNT message of the processing result to the first terminal after receiving and processing the NTFY message of the corresponding relationship between the indicator lights configured on the first terminal and the second terminal.

like:

121) The corresponding relationship of indicator light 0 reported by the first terminal has been correctly processed

RQNT 58208615 aaln/1@test.XXX.com

X: 16002820

R:

S: X-KS/lmrt(0, succ)

or:

122) The processing of the corresponding relationship of indicator light 0 reported by the first terminal failed

RQNT 58208615 aaln/1@test.huawei.com

X: 16002820

R:

S: X-KS/lmrt(0, fail)

123) The processing of the corresponding relationship of indicator light 0 reported by the first terminal fails, while the corresponding relationship of indicator light 1 is successfully processed

RQNT 58208615 aaln/1@test.huawei.com

X: 16002820

R:

S: X-KS/lmrt((0, fail), (1, succ)).

Step 2: The media gateway controller sends the number of the indicator light corresponding to the second terminal and the status indicated by the indicator light to all third terminals subscribing to the status of the second terminal by means of a message, and realizes Speed on the MGCP phone of the IP trunking network. key business.

As shown in Figure 2, the telecom operator can set the status of the third user terminal to subscribe to the status of other second user terminals through the configuration of the first maintenance terminal, as well as the indicator number corresponding to each subscribed second user terminal, and send it to The media gateway controller of the IP trunking network sends the RQNT message with the subscription relationship to the third user terminal by using the extension package of the MGCP protocol.

For example:

21) Indicates that the user number corresponding to the designated light number 0 is 12345678, then

RQNT 58208615 aaln/1@test.XXX.com

X: 16002820

R:

S: X-KS/lmgrp(0, 12345678)//Indicator number 0 corresponds to user number 12345678

or:

22) The user number corresponding to indicator light 0 is specified as 12345678, and the user number corresponding to indicator light 1 is 12345679.

RQNT 58208615 aaln/1@test.XXX.com

X: 16002820

R:

S: X-KS/lmgrp ((0, 12345678), (1, 12345679))

Step 3: When the situation of the terminal changes, the media gateway controller notifies the third terminal subscribing to the state of the second terminal by using the RQNT message.

Step 31: When the state of the second terminal is modified by the first terminal, the media gateway controller records the modification relationship, and uses the RQNT message to notify all third terminals subscribed to the state of the second terminal of the second terminal corresponding to each indicator light. terminal number.

When the telecom operator modifies the state of subscribing to other second user terminals through the first terminal, after the media gateway controller records the modification relationship, it needs to notify all the third terminals subscribing to the state of the second terminal by using the RQNT message. The corresponding second end user number.

In the embodiment of the present invention, since the third user terminal must be an IP trunking network user, the first terminal only needs to know the user's IP trunking network number, and notify the relationship of the indicator light corresponding to the IP trunking network number through the RQNT message The third terminal is sufficient, and the format of the RQNT message is the same as that in step 11.

Step 32: When the third terminal subscribing to the status of the second terminal re-registers with the media gateway controller, the media gateway controller uses the RQNT message to notify the third terminal subscribing to the status of the second terminal of the second terminal corresponding to each indicator light Number.

As shown in Figure 3, when the third terminal subscribing to the state of the second terminal re-registers with the media gateway controller, the media gateway controller also needs to notify the third terminal subscribing to the state of the second terminal that each indicator light corresponds to the first 2. User terminal number.

Wherein, RSIP is used to notify the MGC that a terminal (Endpoint) intends to participate in or withdraw from the MGCP service, and in the embodiment of the present invention, the third terminal re-registers with the MGC.

like:

321) The user number corresponding to the indicator light number 0 is specified as 12345678, then

RQNT 58208615 aaln/1@test.XXX.com

X: 16002820

R:

S: X-KS/lmgrp(0, 12345678)

or

322) It is specified that the user number corresponding to indicator light number 0 is 12345678, and the user number corresponding to indicator light number 1 is 12345679, then

RQNT 58208615 aaln/1@test.huawei.com

X: 16002820

R:

S: X-KS/lmgrp ((0, 12345678), (1, 12345679))

Step 33: When the state of the second terminal changes, the media gateway controller broadcasts the state of the second terminal to all third terminals that have subscribed to the state of the second terminal through an RQNT message.

As shown in Fig. 4, when the state of the second terminal changes, the media gateway controller needs to broadcast the state of the second terminal to all third terminals that have subscribed to the state through an RQNT message.

For example:

331) The current state of the user terminal corresponding to the designated indicator light number 0 is busy (busy), then

RQNT 58208615 aaln/1@test.huawei.com

X: 16002820

R:

S: X-KS/lmsts(0, busy)

332) The current state of the user terminal corresponding to the designated indicator light number 0 is busy (busy), and the current state of the user corresponding to the indicator light number 1 is idle (idle), then

RQNT 58208615 aaln/1@test.huawei.com

X: 16002820

R:

S: X-KS/lmsts((0, busy), (1, idle))

Those skilled in the art can understand that the first terminal, the second terminal and the third terminal in the present invention may be terminals in the same IP cluster network, or different IP cluster network terminals.

The following example illustrates the process of implementing the Speed key function on the terminal, such as one-key pickup, hold and resume call, call transfer and other one-key quick operation services:

One-key pickup: Usually, if user terminal A wants to pick up the call of user terminal B, it must first know whether user terminal B is in the ringing state, and then pick up the access code and dial the phone number of user terminal B Number. However, in the present invention, as long as user terminal A subscribes to user terminal B, after the softswitch gateway corresponds a certain indicator light to the number of user terminal B, when user terminal B rings, user terminal A can go off-hook Simply press the button corresponding to the indicator light to realize the pickup function.

One-key hold and resume call: When the user is on a call, the user can press a button to put the call on hold (Call Park), and other phones that have subscribed to the user's status will display that the user is on hold, and then on these phones to pick up the held call by pressing the button corresponding to the indicator light.

One-key call transfer: During a call, user terminal A can call another user terminal C by pressing the button corresponding to the idle state indicator light. At this time, user terminal B is listening to music and is in a suspended state. Terminal C can communicate with user terminal B after answering. Alternatively, user terminal A hangs up after talking with user terminal C, and user terminal C and user terminal B directly enter a talking state.

This embodiment is a detailed description for a better understanding of the present invention, and is not a limitation of the protection scope of the present invention. Changes are within the protection scope of the present invention.
