Description

 Method, device and system for transmitting voice messages by multipath

 This application is submitted to the Chinese Patent Office on December 31, 2010, and the application number is

201010620239.0, the entire disclosure of which is hereby incorporated by reference in its entirety in its entirety in its entirety in the the the the the the the the the the the the Technical field

 The present invention relates to the field of communications, and in particular, to a method, device, and system for transmitting voice messages in multiple paths. Background technique

 With the comprehensive advancement of the Internet (Internet Protocol), the traditional voice has gradually changed to the IP bearer. To improve the reliability of voice services, dual-plane networking is often used. When there is a problem with one plane, the business all switches to another plane. The MGW (Media GateWay, Media Gateway) in the current core network is an independent allocation of IP resources. Therefore, if there is a problem inside the bearer network, the IP path that the access service uses to the fault will inevitably occur, resulting in poor voice quality and affecting the user experience.

 In order to improve the voice quality, the prior art fully utilizes the multi-path of the bearer network to ensure that the accessed voice service is guaranteed by QoS (Quality of Service), and when the voice is transmitted through the multipath, the signaling is first adopted. The face exchange determines an RTP (Rea lt ime Transpor t Protocol) / RTCP (RTP Cont rol Protoco l, RTP Control Protocol) flow, and then negotiates another RTP/RTCP through the extension header of the RTP/RTCP flow. Stream, such a stream will evolve into two streams, that is, to achieve dual-issue selection.

In the process of implementing the present invention, the inventors have found that the prior art has at least the following disadvantages: When transmitting voice packets by using multiple paths, if it is ensured that the accessed voice service is guaranteed by QoS, it is necessary to ensure that two independent paths are finally obtained. However, the prior art cannot determine whether the obtained path is independent; and the dual-selection mode cannot satisfy all scenarios, and in an area where the bandwidth is not rich, it may only need to maintain one RTP stream if the originally established RTP path is If the fault occurs, it will affect the establishment of the new path. In severe cases, the establishment of the path will completely fail, and thus the QoS cannot be guaranteed. Summary of the invention

Embodiment 2

 The embodiment provides a method for transmitting a voice message by using a multi-path device. The method sends the path negotiation information including the interface location information and the media stream state requirement information to the peer device by the one-end device to implement the voice message of the device at both ends. The transmission path is negotiated, so that the devices at both ends can ensure that the accessed voice service is QoS guaranteed and meets the scenario requirements. The device that initiates the path negotiation and the device that receives the negotiation request may be an MGW, or may be a terminal, a base station, a base station controller, etc., which is not specifically limited in this embodiment. For convenience of description, in this embodiment, the device that initiates the path negotiation is the first device, and the peer device is the second device, and the media stream state determined by the second device is a single stream, and one path for transmitting the voice packet is the original path. The other path is a new path as an example, and the method provided in this embodiment is described in detail. Referring to FIG. 2, the process of the method provided in this embodiment is specifically as follows:

 201: The first device sends path negotiation information to the second device, where the path negotiation information carries at least one address, interface location information, and media stream state requirement information.

 For this step, the method does not limit the manner in which the first device sends the path negotiation information to the second device. In the implementation, the path negotiation information may be carried in the extended signaling parameter and sent to the peer device, or The path negotiation information is carried in the voice message and sent to the peer device. The path negotiation information carries at least the backup address, the interface location information, and the media stream state requirement information, and the interface location information may be domain or plane information, and the media stream state request information is used. To describe the requirements of the media stream state, the specific content of the interface location information and the media stream state requirement information is not limited in this embodiment.

When the path negotiation information is transmitted in the manner of extending signaling parameters, the extended signaling parameters may be as follows Rr :

 A= mpr tp <network type> <addres s type> connect ion addres s> < IP Doma in/P lane> A= mpr tps ta te {Onepa th | Twopa th | backup}

 The mpr tp is used to carry the IP address, the network type indicates the network type, the connect ion addres s indicates the link address, and the IP Doma in/P lane indicates the location of the carried IP address. If this information is carried, it means that it is different from the primary IP address (the primary IP address is carried by c = IN4/ IN6 X. X. X. X). Mpr tps tate indicates the status of the media stream. Onepath indicates that the media stream status is single stream, Twopath indicates that the media stream status is dual-transmit, and backup indicates that the media stream status is single-stream backup.

 When the path negotiation information is sent in the form of a voice message, the voice message may be an RTP message, and a type for describing the state of the media stream may be added to the voice message, for example, adding 0x3 to the MPR_Type. Type, and the capability of the first device and the capability of the second device are described by the type, such as: the ability of the first device is represented by Send, and the capability of the second device is represented by Receive.

 202: The second device determines the media stream state and the path address according to the path negotiation information, and returns the determined media stream state and the path address thereof to the first device, where the determined media stream state is a single stream;

 Specifically, the second device sends the path negotiation information to the second device, and after receiving the path negotiation information, the second device determines the final media stream state according to the capability of the second device. In addition, the path address will be determined based on the path negotiation information. In the implementation application, the second device may determine the media stream state according to the media stream state requirement information in the path negotiation information, and determine the path address according to the interface location information in the path negotiation information.

 For this step, if the second device determines that the current bandwidth is insufficient according to the media stream state requirement information in the path negotiation information, the media stream state may be determined as a single stream. For the path address determined by the second device, since the path address is determined according to the interface location information in the path negotiation information, and the interface location information may be domain or plane information, the second device may be in the same domain or plane. The IP address is selected as the path address, that is, the corresponding IP resource is allocated, and the path address matches the address carried in the path negotiation information, so that the voice message can be transmitted on a completely different path, thereby ensuring QoS.

Further, when the determined media stream state and its path address are returned to the first device as a negotiation result, the same manner as the first device sends the path negotiation information, and the extended signaling parameter may be adopted. If the voice message is an RTP message, the negotiation result is returned to the first device through the RTCP message, and the message is returned to the first device. The return mode is not limited in this embodiment.

 203: The first device receives the negotiation result returned by the second device, selects the original path in the original path and the new path according to the negotiation result, and transmits the voice message through the original path and the second device.

 For this step, the status of the media stream in the negotiation result is a single stream. Therefore, when the first device selects a path for transmitting a voice message with the second device in the original path and the new path according to the negotiation result, the original path may be selected. A new path may be selected, which is not specifically limited in this embodiment. This step is only described by taking the source path of the first device as an example.

 204: The first device selects a new path in the original path and the new path according to the negotiation result, and sends a voice message to the second device by using the new path.

 In this step, the status of the media stream in the negotiation result is a single stream. Therefore, when the first device selects a path for transmitting the voice message with the second device in the original path and the new path according to the negotiation result, the path is selected through the original path and the second path. After the device sends a voice packet, it can also choose to send a voice packet to the second device through the new path.

 205: After receiving the voice message sent by the first device by using the new path, the second device turns off the original path, and sends a voice message to the first device by using the new path.

 Specifically, since the media stream state determined by the second device in the foregoing step 202 is a single stream, after the second device receives the voice message sent by the first device through the new path, it means that the original path becomes unused. Path, in order to guarantee a single stream, the second device will close the original path.

 Preferably, after the original device is closed, the second device can also recover the address resources of the original path, thereby saving resources.

 206: After receiving the voice message sent by the second device by using the new path, the first device turns off the original path, and transmits the voice message to the second device by using the new path.

 With the above step 205, since the media stream state determined by the second device in the foregoing step 202 is a single stream, after the first device receives the voice message sent by the second device through the new path, it means that the original path becomes The path is not used. To ensure a single stream, the first device also closes the original path.

After the original device closes the original path, the address resource of the original path can also be recovered, thereby saving resources. The method provided in this embodiment is to send the path negotiation information to the second device by using the first device, perform path negotiation with the first device, and add the interface location information to the path negotiation information, so that the second device can be in the same domain or plane. Assigning an address in the middle ensures that the new path uses a different path, ensuring that the accessed voice service is guaranteed by QoS. In addition, by adding the media stream state requirement information to the path negotiation information, the second device determines the media stream according to the call situation. The status, which in turn satisfies the needs of the scene. Embodiment 3

 The embodiment provides a method for transmitting a voice message by using a multi-path device. The method sends the path negotiation information including the interface location information and the media stream state requirement information to the peer device by the one-end device to implement the voice message of the device at both ends. The transmission path is negotiated, so that the devices at both ends can ensure that the accessed voice service is QoS guaranteed and meets the scenario requirements. For the convenience of the description, the device that initiates the path negotiation is the first device, and the peer end is the second device, and the media stream state determined by the second device is a single stream backup, and one path of the voice packet is transmitted. For the original path, the other path is a new path, and the new path is determined as a backup path in the original path and the new path. The method provided in this embodiment is described in detail. Referring to FIG. 3, the method of the method provided in this embodiment is specifically as follows:

 301: The first device sends path negotiation information to the second device, where the path negotiation information carries at least one address, interface location information, and media stream state requirement information.

 The step is the same as the step 201 in the foregoing embodiment 2. For details, refer to the step 201 in the foregoing embodiment 2, and details are not described herein again.

 The second device determines the media stream state and the path address according to the path negotiation information, and returns the determined media stream state and the path address to the first device as a negotiation result, where the determined media stream state is a single stream backup;

For the step, in the same manner as the step 202 in the second embodiment, the second device sends the path negotiation information to the second device, and the second device receives the path negotiation information according to the second device. The ability to determine the final media stream state, in addition, will also determine the path address based on the path negotiation information. In the implementation, the second device may determine the media stream state according to the media stream state requirement information in the path negotiation information, and determine the path address according to the interface location information in the path negotiation information. And because the path address is determined according to interface location information in the path negotiation information, and the connection is The port location information may be domain or plane information. Therefore, the second device may select an IP address as the path address in the same domain or plane, that is, allocate the corresponding IP resource, and the path address and the address carried in the path negotiation information are Matching, thus ensuring that voice messages are transmitted on completely different paths, thereby ensuring QoS.

 In addition, when the determined media stream state and the path address are returned to the first device as the negotiation result, the manner in which the first device sends the path negotiation information may be returned to the first device by using the extended signaling parameter. The voice control packet can be returned to the first device by using a voice control packet. If the voice packet is an RTP packet, the negotiation result can be returned to the first device through the RTCP packet, and the specific return mode is adopted. The example is not limited.

 Different from the step 202 in the second embodiment, if the second device determines the media stream state as a single stream backup according to the media stream state requirement information in the path negotiation information, the second device needs to be in the original path and the new path. Determine any path as a backup path. In this embodiment, a new path is taken as a backup path as an example.

 303: The first device receives the negotiation result returned by the second device, determines that the new path is the backup path, and transmits the voice message to the second device by using the original path.

 Specifically, the status of the media stream in the negotiation result returned by the second device is a single-stream backup. After receiving the negotiation result returned by the second device, the first device determines that the new path is the backup path according to the negotiation result, and passes the The original path and the second device transmit voice messages.

 304: The first device does not receive the voice message sent by the second device by using the original path, and sends a voice message to the second device by using the new path.

 For the first step, if the first device does not receive the voice message sent by the second device through the original path, the first device may determine that the original path is faulty. To ensure the normal transmission of the voice message, the first device enables the backup. The path, that is, the voice message is sent to the second device through the new path.

 In this embodiment, the specific preset time is not limited. In an actual application, the first device and the second device may be pre-negotiated. For example, after 20 milliseconds, the first device still does not receive the second device and sends the original device through the original path. A voice packet can send a voice packet to the second device through the new path.

It should be noted that, in addition to the first device not receiving the voice message sent by the second device through the original path, the backup device may enable the backup path if the first device determines that the packet is lost. Similarly, except for the first device, the backup path can be enabled, and if the second device is at the preset time If the voice packet sent by the first device is not received or the packet is lost, the backup path can be enabled, that is, the voice packet is sent to the second device through the new path. In addition, whether the first device or the second device receives the voice packet sent by the peer device through the backup path, the backup path can be used to send the voice packet to the peer device.

 305: After receiving the voice message sent by the first device by using the new path, the second device sends a voice message to the first device by using the new path.

 Specifically, because the media stream state determined by the second device in the foregoing step 302 is a single stream backup, that is, one voice path is transmitted by using one path of the original path and the new path, and the other path is used as the backup path, then the second path is used. After the device receives the voice message sent by the first device through the new path, the second device also sends a voice message to the first device through the new path.

 Preferably, in order to save resources, when the second device receives the voice message sent by the first device through the new path, and then sends the voice message to the first device through the new path, the second device may also close the original path and collect the voice packet. The address resource of the original path. Similarly, after receiving the voice message sent by the second device through the new path, the first device may also close the original path and recover the address resource of the original path.

 The method provided in this embodiment is to send the path negotiation information to the second device by using the first device, perform path negotiation with the first device, and add the interface location information to the path negotiation information, so that the second device can be in the same domain or plane. Assigning an address in the middle ensures that the new path uses a different path, ensuring that the accessed voice service is guaranteed by QoS. In addition, by adding the media stream state requirement information to the path negotiation information, the second device determines the media stream according to the call situation. The status, which in turn satisfies the needs of the scene. Embodiment 4
