Embodiment
Core concept of the present invention is: when adopting IP protocol transmission voice in the wireless network, at first determine to belong to the voice packet of same speech channel; Voice packet with described same speech channel is sent to identical port then, and transmits by identical path.
For the present invention there being further understanding, method of the present invention is described in detail below in conjunction with accompanying drawing.
The specific implementation of the method for the invention may further comprise the steps as shown in Figure 3:
Step 31: under the IP transmission situation, set up in the process in the wireless network, for speech channel distributes the speech channel sign in speech channel.
Speech channel sign can adopt datagram protocol udp port number or GRE (Generic Routing Encapsulation) key value or other modes to represent.
According to the regulation of existing protocol, adopt the method for udp port number sign speech channel to be:
During call setup, at local terminal, such as: (the Base Station Controller of the BSC among the CDMA, base station controller), perhaps (the Radio Network Controller of the RNC among the WCDMA, radio network controller) distributes a udp port number for this speech channel, number notify the opposite end by call signaling with the udp port that distributes, be BTS (the Base Transceiver Station among the CDMA, base transceiver station), the perhaps Node B among the WCDMA, like this between BSC among the CDMA and the CBTS or a speech channel between RNC among the WCDMA and the Node B just determined.
Udp port number is exactly the speech channel sign that two equipment rooms of local terminal and opposite end are determined when conversing.
Step 32: speech channel set up in the process distribute the speech channel sign for speech channel after, be speech channel distribution corresponding link again.
Step 33: set up the corresponding relation between speech channel sign and the respective link, just a speech channel sign is bound with a corresponding link.
Step 34: encapsulation voice IP packet.
When the voice packet to certain bar speech channel carries out the IP packet encapsulation, with purpose IP address and the information-bearing such as chain line (such as udp port number) of distributing to this speech channel in the IP packet.
Step 35: when voice IP packet is carrying out routing and sends, distributor obtains the speech channel identification information that voice IP packet is carried, corresponding relation according to speech channel sign and link is determined corresponding link, and voice IP packet is sent to the physical port of this link, thereby voice IP packet is transmitted by this link.
Adopt the method for above-mentioned transmission of voice packets, the voice packet that just can guarantee same speech channel transmits by identical link, as shown in Figure 4, such as, the voice packet of speech channel 1 all transmits by link 3, the voice packet of speech channel 2 and speech channel 3 all transmits by link 1, and the voice packet of speech channel 4 all transmits by link 2.Thereby the out of order problem that the voice packet that has solved a speech channel is produced when assigning to different link transmission by distributor, even and certain link take place congestedly, it is out of order that the voice packet of this link bearer is produced, thereby guaranteed voice quality.
Step 36: behind end of conversation, discharge speech channel sign (such as udp port number) and concern with corresponding (i.e. the binding) of respective link.
Can improve the utilance of resource like this, on the one hand; On the other hand, when setting up speech channel next time,, call out normal foundation thereby make if this link occurs fault can be bound the speech channel sign so with other link.
The present invention also provides the device of transmission of voice packets in a kind of wireless network, and this device comprises: the transmission of voice packets module, be arranged in the distributor, and its function is:
When in wireless network, adopting IP protocol transmission voice packet, the voice packet of same speech channel is sent to identical physical port, transmits by identical link.
The function of transmission of voice packets module can realize that wherein, the function of speech channel sign and link assignment submodule is by speech channel sign and link assignment submodule and transmission of voice packets submodule:
When speech channel is set up,, and preserve the corresponding relation of speech channel sign and respective link for speech channel distributes speech channel sign and corresponding link;
The function of transmission of voice packets submodule is:
When voice IP packet carries out the routing transmission, obtain the speech channel sign of carrying in the described voice packet, determine this speech channel sign link corresponding according to the corresponding relation of speech channel sign and link, and voice IP packet is sent to the physical port of definite link.
This device also comprises: speech channel sign and link corresponding relation release module, be arranged in the distributor, and its function is:
Behind end of conversation, discharge the speech channel sign be kept in speech channel sign and the link assignment submodule and the corresponding relation of respective link.
In sum, adopt method of the present invention and device, the voice packet of same speech channel is transmitted on same paths, can solve the out of order problem of voice under IP transmission situation effectively, thereby improve voice quality.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
