(2) Wired telephone equipment and wired Access voice Access Gateway, where the wired Access voice Access Gateway may be deployed in a cell and independently deployed as a Gateway of multiple wired telephone equipment, and the wired Access voice Access Gateway may also be deployed in a home, for example, it may be an Access Gateway (AG), integrated in the wired telephone equipment or deployed as an independent wired telephone equipment, and the wired telephone equipment may be a commonly-used landline telephone or the like.

When different users call, a first telephone device of a first user performs signaling interaction with a second telephone device through a first voice access gateway, an IP Multimedia System (IMS) and a second voice access gateway of a second user. The specific deployment of IMS may be various and is not limited herein.

The above-mentioned telephone device and voice access gateway may respectively correspond to the terminal device side and the network device side according to different deployment manners, and the following describes an embodiment of the present application with reference to the accompanying drawings.

Referring to fig. 4a, fig. 4a is a flowchart illustrating a call establishment method according to an embodiment of the present application, where the method may be implemented based on the communication system shown in fig. 1; the method includes, but is not limited to, the steps of:

step S4a 01: the first voice access gateway receives a first ringing signaling from a second voice access gateway, and notifies a first device calling a second device to ring, wherein the first ringing signaling is sent when the second voice access gateway detects that a target device called by the second device is the first device.

The first Ringing signaling may be a 180/Ringing message, and the Ringing of the first device means that the first device emits a paging Ringing prompt tone in the paging process, which is similar to a beep sound, or a color ring, etc. The first voice access gateway is a voice access gateway associated with the first device, and the second voice access gateway is a voice access gateway associated with the second device.

In a specific implementation, the second voice access gateway detects that a target device that the second device is calling is the first device, and may compare a device Identifier of the target device with a device Identifier of the first device, where the device Identifier may be, for example, a phone number (a calling number, a called number), an International Mobile Equipment Identity (IMEI), a Mobile Equipment Identity (MEID), an integrated Circuit Card Identity (ic), and the like, and is not limited uniquely here.

Step S4a 02: the first voice access gateway interacts with the second voice access gateway to establish a voice channel between the first device and the second device.

The voice channel may be a circuit domain voice channel or a packet domain voice channel, and is not limited herein.

In one possible example, the first voice access gateway interacting with the second voice access gateway to establish a voice channel between the first device and the second device includes: after detecting that the ringing frequency of the first device is greater than or equal to a preset frequency, the first voice access gateway sends a first response signaling to the second voice access gateway, wherein the first response signaling is used for the second voice access gateway to execute a preset operation so as to prompt the first voice access gateway to receive the preset signaling; and the first voice access gateway receives the preset signaling, and establishes a voice channel between the first device and the second device according to the preset signaling.

Wherein the first acknowledgement signaling may be a 100/Trying message. The preset signaling is used for indicating the state of the voice channel, if the preset signaling indicates that the voice channel is not established, the first voice access gateway initiates a voice channel establishing process, and if the preset instruction indicates that the voice channel is established by the second voice access gateway, the second voice access gateway initiates the voice channel establishing process.

The preset number of times may be 2 times, 3 times, etc., and is not limited herein.

The preset operation may be a voice channel establishing operation or a response signaling sending operation, and is not limited specifically.

In this example, in a call-to-call scenario, the first voice access gateway sends the first response signaling to the second voice access gateway through the constraint of the number of rings, so as to ensure that the first device user does not hang up the phone call, and trigger the second voice access gateway to execute a preset operation, and the first voice access gateway receives the preset signaling and establishes a voice channel according to the preset signaling. The stability of call establishment is improved.

In one possible example, the preset signaling is a second acknowledgement, ACK, signaling; the second ACK signaling is sent by the second voice access gateway when the first response signaling is received and the first ACK signaling from the first voice access gateway is not received; the first voice access gateway establishes a voice channel between the first device and the second device according to the preset signaling, including: and the first voice access gateway responds to the second ACK signaling and initiates a first voice channel establishing process to establish the voice channel.

The first voice channel establishing process adopts a channel establishing process agreed by the existing standard protocol, and is not limited herein.

In a call-to-call scenario, the first device serves as a calling device to call the second device, and the second device also serves as a calling device to call the first device, so that the second device can also initiate a flow initiated by the first device, and at this time, by restricting a gateway, which receives an ACK signaling first, of the first voice access gateway and the second voice access gateway to initiate a voice channel establishment process, resource use conflicts caused by the voice channel establishment process initiated by the first voice access gateway and the second voice access gateway, which are all indistinguishable, can be avoided to a certain extent, and the stability of call establishment is improved.

As can be seen, in this example, for the case that the first voice access gateway receives the ACK signaling of the opposite end before the second voice access gateway, the first voice access network initiates the ACK signaling, so that resource usage conflicts caused by indiscriminate voice channel establishment initiation processes of the first voice access gateway and the second voice access gateway can be avoided to a certain extent, and stability of call establishment is improved.

In a possible example, the preset signaling is a voice channel establishment request, where the voice channel establishment request belongs to signaling in a second voice channel establishment procedure initiated by the second voice access gateway, and the second voice channel establishment procedure is initiated by the second voice access gateway after receiving a first ACK signaling from the first voice access gateway; the first voice access gateway establishes a voice channel between the first device and the second device according to the preset signaling, including: and the first voice access gateway responds to the voice channel establishment request to establish the voice channel.

The second voice channel establishing process adopts a channel establishing process agreed by the existing standard protocol, and is not limited herein. The voice channel establishing request may be an off-hook 200/OK message, and correspondingly, the first voice access gateway responds to the voice channel establishing request and sends an ACK message indicating an off-hook confirmation to the second voice access gateway, thereby establishing the voice channel.

As can be seen, in this example, for the case that the second voice access gateway receives the ACK signaling of the opposite terminal before the first voice access gateway, the second voice access network initiates the ACK signaling, so that resource usage conflicts caused by indiscriminate voice channel establishment initiation processes of the second voice access gateway and the first voice access gateway can be avoided to a certain extent, and the stability of call establishment is improved.

In one possible example, before the first voice access gateway receives the first ringing signaling from the second voice access gateway, the method further comprises: the first voice access gateway acquires a paging request of first equipment, wherein the paging request comprises a called identifier of second equipment; the first voice access gateway sends an invitation signaling to the second voice access gateway, wherein the invitation signaling comprises a calling identity of the first device and a called identity of the second device, and the invitation signaling is used for the second voice access gateway to execute the following operations: sending a first response signaling to the first voice access gateway; detecting that the second device is busy; judging that the target device which is called by the second device is the first device, and sending the first ringing signaling to the first voice access gateway; the first voice access gateway receives a first response signaling from the second voice access gateway.

The paging request may be, for example, a dialing instruction or an off-hook instruction, the INVITE signaling may be, for example, an INVITE message, the first response signaling may be, for example, a 100/Trying message, and the first Ringing signaling may be, for example, a 180/Ringing message.

As can be seen, in this example, the first voice access gateway triggers the second voice access gateway to perform the detection of the call-to-call event, so as to accurately locate the call-to-call scenario, and improve the accuracy of call establishment in the call-to-call scenario.

In one possible example, the method further comprises: the first voice access gateway receives a busy signaling from the second voice access gateway and informs the first equipment of outputting busy notification information; the busy signaling is obtained by the second voice access gateway after receiving the invite signaling, and the second voice access gateway performs the following operations: and judging that the target device called by the second device is not the first device.

As can be seen, in the present example, for a non-opposite call scenario, the original busy processing mechanism is still used, so that it is ensured that a calling party does not conflict due to the establishment of multiple voice channels for simultaneous use, and the call stability in a multi-call scenario is improved.

Furthermore, for the specific case where the first voice access gateway and the second voice access gateway establish voice channels completely simultaneously, collisions can be avoided by the following collision resolution mechanism.

The first voice access gateway and the second voice access gateway respectively generate a random number, and a voice channel established by the voice access gateway with the larger random number is selected for use by comparing the random numbers.

Step S4b 02: the second voice access gateway interacts with the first voice access gateway to establish a voice channel between the first device and the second device.

In one possible example, the second voice access gateway interacting with the first voice access gateway to establish a voice channel between the first device and the second device includes: the second voice access gateway receives a first response signaling from the first voice access gateway, wherein the first response signaling is sent by the first voice access gateway after the first voice access gateway detects that the ringing frequency of the first device is greater than or equal to a preset frequency; and the second voice access gateway executes preset operation to inform the first voice access gateway of preset signaling, wherein the preset signaling is used for the first voice access gateway to establish a voice channel between the first equipment and the second equipment.

In one possible example, the preset signaling is a second acknowledgement, ACK, signaling; the second voice access gateway executes preset operation to inform the first voice access gateway of preset signaling, and the method comprises the following steps: the second voice access gateway detects whether a first ACK signaling from the first voice access gateway is received or not; and the second voice access gateway detects that the first ACK signaling is not received, and sends the second ACK signaling to the first voice access gateway, wherein the second ACK signaling is used for the first voice access gateway to initiate a first voice channel establishing process so as to establish the voice channel.

In one possible example, the preset signaling is a voice channel establishment request; the second voice access gateway executes preset operation to prompt the first voice access gateway to receive preset signaling, and the preset operation comprises the following steps: the second voice access gateway detects whether a first ACK signaling from the first voice access gateway is received or not; and the second voice access gateway detects that the first ACK signaling is received, initiates a second voice channel establishing process, and sends the voice channel establishing request to the first voice access gateway, wherein the voice channel establishing request is used for the first voice access gateway to respond to the voice channel establishing request so as to establish the voice channel.

In one possible example, before the second voice access gateway detects that the target device that the second device is calling is the first device, the method further includes: the second voice access gateway receives an invitation signaling from the first voice access gateway, wherein the invitation signaling comprises a calling identification of the first equipment and a called identification of the second equipment; the second voice access gateway sends a first response signaling to the first voice access gateway; the second voice access gateway detects that the second device is busy.
