Specific embodiment
A plurality of embodiments of the present invention will be disclosed below with schema, as clearly stated, thin in many practices
Section will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied to limit the present invention.?
That is, in some embodiments of the present invention, the details in these practices is non-essential.Additionally, for the sake of simplifying schema,
Some known usual structures and element will illustrate it in the drawings in the way of simple signal.
Refer to Fig. 1, it is the flow chart of the 4g voice-over-net data transmission method of the embodiment of the present invention.As shown in figure 1,
For solving the problems, such as bandwidth waste between core net and base station, the invention provides a kind of 4g voice-over-net data transmission method.When
When base station sends speech data to core net, open a thread in base station side, dedicated for group bag, by multiple VoPs
Proprietary protocol according to definition forms a big bag, and every 20ms sends one and is wrapped in greatly core net, the length of each big bag
Less than 1512 bytes；Described core net receives the big bag that described base station is sent, and the proprietary protocol according to definition will wrap greatly solution
Analyse into parcel, then processed.Likewise, also do same packing processing when core net sends speech data to base station.I.e.
Multiple VoPs are formed a big bag according to the proprietary protocol of definition by core net, and every 20ms sends one and is wrapped in greatly
Core net, of length no more than 1512 bytes of each big bag；Described base station receives the big bag that described core net is sent, according to fixed
Big Packet analyzing is become parcel by the proprietary protocol of justice, then is processed.
Base this, by multiple VoPs composition one big bag be transmitted again, network transmission bandwidth can be made full use of,
Improve the voice data transmission speed of base station and core net, thus lifting the number of terminals that online audio call simultaneously is supported in base station.
Further, as shown in table 1, the form of the speech data before not packing is 3gpp (the 3rd generation
Partnership project) form that specifies of agreement, including ip head (internet protocol), udp head (user
Datagram protocol), gtp head (gprs tunnelling protocol) data it may be assumed that ip head+udp head+gtp head+
Data.
Table 1
As shown in table 2, the self-defining form of described big Bao Zewei, comprising: ip head, udp head and several by udp head, gtp
The data of head data composition it may be assumed that ip head+udp head+(udp1+gtp1+ data)+...+(udp2+gtp2+ data).
Table 2
Wherein, the udp head in Tables 1 and 2 includes source port (source port) and destination port (mesh
Port), be fixed port 12000.
It is exactly the cumulative of gtp bag in data.Have the pseudo- head of 4 bytes before each gtp head, wherein source port and
Destination port is the source and destination port of the udp in original voice packet, length be immediately following a gtp bag
Length.Type is reserved field.
Accordingly, refer to Fig. 2, it is the structure of the 4g voice-over-net data transmission system of invention embodiment
Schematic diagram.As shown in Fig. 2 the present invention also provides a kind of 4g voice-over-net data transmission system, comprising: base station 1 and core net 2,
Wherein,
When base station 1 sends speech data to core net 2,
Base station 1, for group bag, multiple VoPs is formed one and wraps greatly, and of length no more than the 1512 of described big bag
Individual byte,
Core net 2, for receiving the big bag that described base station 1 is sent, big Packet analyzing is become parcel to be processed again；
When core net 2 sends speech data to base station 1, also do same packing and process,
Core net 2, for group bag, multiple VoPs is formed a big bag,
Base station 1, for receiving the big bag that described core net 2 is sent, big Packet analyzing is become parcel to be processed again.
Specifically, the form that the form of described speech data specifies for 3gpp agreement, including ip head, udp head, gtp head and
Data, the self-defining form of described big Bao Zewei, comprising: ip head, udp head and several be made up of udp head, gtp head data
Data.Described udp head includes source port and destination interface, and described source port and destination interface are fixed port 12000.
As shown in table 3 it can be seen that after using the 4g voice-over-net data transmission method of the present invention and Transmission system, property
Can improve a lot, while base station is supported, audio call number of terminals increased, network rate also increases that is to say, that bandwidth
Utilization rate increased.
