Specific embodiment
The exemplary embodiment for embodying feature of present invention and advantage will describe in detail in the following description.It should be understood that
The present invention can have various variations in different embodiments, neither depart from the scope of the present invention, and theory therein
Bright and diagram inherently is illustrated as being used, rather than to limit the present invention.
As previously described, the uplink of data and downlink transfer require matching in base station and core net in group service
Lower realization is closed, for example, terminal accesses wireless network by base station, the data uploaded will be sent in core net by base station, into
And cluster application server is transmitted upstream to by core net, to realize the upload of data, and store to cluster application server.
And the data in cluster application server will also be transmitted to terminal by core net and base station down, due to cluster industry
Data in business are mostly audio data even video data, therefore bottleneck will be present in core net, and then there are larger biographies
Defeated time delay.
In consideration of it, a kind of special control method proposed in group service data transmission, to realize data in group service
Quick transmission.
In one embodiment, this method is applied to the data transmission between the network equipment, specifically, as shown in Fig. 2, one
Control method in kind group service data transmission, is executed by core net, is included the following steps:
Step 110, the link between the network equipment is established when the transmission of group service data is triggered, group service data pass
It is defeated to carry out between the network devices.
The network equipment is the host to the data acquisition and upload service of realizing terminal, as realization data transmission
Node will have respectively the acquisition and store function of network insertion, data, and therefore, in one embodiment, which can
To be base station, it is also possible to cluster application server.
On the other hand, each network equipment transmitted for realizing group service data, passes according to different data
Defeated process will be divided into transmitting terminal and receiving end.For example, base station is requested to cluster application server, then taken in this cluster application
The data downstream that device carries out of being engaged in is transmitted, wherein cluster application server is transmitting terminal, and base station is receiving end；In base station to cluster
During application server uploads data, base station is transmitting terminal, and cluster application server is then receiving end.
It follows that establish between the network equipment of link, receiving end and transmitting terminal are in contrast, and to be adapted to
Different data transmission procedure and opposite change.
Core net will be transmitted across the data between the network equipment as the network of group service is provided in data transmission
Cheng Jinhang control, so that the network equipment is achieved data transmission.
Specifically, core net will initially set up the network equipment, i.e., between transmitting terminal and receiving end to realize group service
Link, the link are specially transmitting terminal ← → core net ← → receiving end link, wherein base station and cluster application server will
Receiving end and transmitting terminal each other.
Step 130, the address mark of the network equipment is obtained.
After link establishment between transmitting terminal, core net and receiving end, triggering is obtained each network equipment by core net
Address mark, i.e. the address mark of transmitting terminal itself and the address of receiving end itself identify.Wherein, address mark will be used respectively
In the position of label transmitting terminal and receiving end in a network.Address mark can be network address (IP address, Internet
Protocol Address), it can also be by network address and tunnel endpoint identifier (TEID, Tunnel Endpoint ID) structure
At, herein without limit, can be configured as needed.
Step 150, itself is issued by the chain road direction network equipment between the network equipment and carries out the transmission of group service data
Destination address mark, pass through destination address identify issue alternative networks equipment itself storage destination address.
When the transmission of group service data is triggered, process as described above is carried out by core net, and then is able to triggering structure
The channel of group service data transmission is carried out between establishing network equipment.
Since constructed channel is that the destination address mark that core net issues carries out, which is relatively core
The bypass channel of heart net, and then obtain the transmission for directly carrying out group service data between the network devices.
Core net will be identified down by address after knowing the respective address mark of the network equipment and send each net of triggering
The replacement of address in network equipment.
Wherein, for a network equipment, the address mark that core net is issued to it is the ground of another network equipment
Location mark；In other words, opposite present networks equipment, another network equipment is as its target network in the transmission of group service data
The destination address that itself is stored is replaced with the address that core net issues by present networks equipment and identified, i.e., so that mesh by network equipment
Address identified by the address that the address of core net replaces with destination network device, and then can be realized between two network equipments
Direct communication.
In the group service data transmission triggered, address replacement includes the address replacement in transmitting terminal, relatively
It answers, also includes the address replacement in receiving end.
That is, for transmitting terminal, under the control of core net, will realize the downlink destination address of its communication according to
The address mark of receiving end itself is replaced；It is corresponding, for receiving end, also under the control of core net, will realize
Its uplink destination address communicated is replaced according to the address mark of transmitting terminal itself.
The replacement process of address is carried out by each network equipment, can be achieved directly so that transmitting terminal and receiving end store respectively
Connect letter uplink destination address and downlink destination address, thus can directly according to uplink destination address and downlink destination address by
Road core net constructs the channel that group service data transmission is directly carried out between transmitting terminal and receiving end.
The process of bypass core net as described above does not need additionally to carry out relevant parameter for example, access point name
Configuration, and only need to carry out the network equipment address replacement, and additional data will not be generated, reducing the same of time delay
When, also ensure that the convenience of realization is simple.
Further, in the present embodiment, the network equipment includes base station and cluster application server, as shown in figure 3, the step
Rapid 150 include:
Step 151, uplink destination address mark and downlink destination address mark are extracted from the mark of the address of acquisition.
As previously described, address mark includes IP address (Internet Protocol Address, network address),
Alternatively, IP address and TEID (Tunnel Endpoint ID, tunnel endpoint identifier).
In the group service data transmission that triggering carries out, between related two network equipments, a network equipment will
Destination network device as another network equipment.After the address mark for acquiring the network equipment, cluster industry will be carried out
The address mark for data upstream transmission of being engaged in is identified as uplink destination address, will carry out the address of group service data downstream transmission
Mark is identified as downlink destination address.
As previously described, the network equipment includes base station and cluster application server, therefore, the ground of cluster application server
Location mark is identified as uplink destination address, and the address mark of base station is then identified as downlink destination address.
Step 153, itself is issued by the chain road direction base station between base station and cluster application server and carries out group service
The uplink destination address of data upload transfers identifies, and issues itself to cluster application server and carries out group service data downstream number
It is identified according to the downlink destination address of transmission.
Uplink destination address that core net is carried out mark issues that issue with downlink destination address mark can be by receiving ground
What the transmission of location notification message was realized.
The address mark of the network equipment of acquisition is contained in the reception address notification message.Specifically, the network equipment
Address mark the uplink destination address mark for being its uplink transmission data or downlink destination address are identified, core net passes through
It sends this and receives address notification message to control the replacement that there is purpose address in network equipment Central Plains.
Specifically, core net will be answered to cluster each other between transmitting terminal and the cluster application server and base station of receiving end
Address notification message is transmitted and received with server, the address that address notification message includes cluster application server is received and identifies, to
Reception address notification message corresponding to the signalling of bouquet application server of base station, to reception address notification message transmitted by base station
Address mark comprising base station.
The network equipment, which receives, receives address notification message, will can send to core net and respond accordingly, with to core
The reception address notification message that net feeds back transmitted by it has been received, so that core net confirms that reception address notice disappears
Breath is sent to.
It should be noted that including in the reception address notification message that core net is sent respectively for each network equipment
Address mark will be unified for IP address or IP address and TEID.
In one embodiment, a kind of group service data transmission method has been also correspondingly provided, this method is applied to net
Data transmission between network equipment, and executed by the network equipment, as shown in figure 4, including the following steps:
Step 210, itself link between core net is established when the transmission of group service data is triggered.
Step 230, the destination address that core net issues is received by link to identify.
As previously described, the destination address mark that core net is carried out, which issues, to be realized by receiving address notification message
's.
In the network equipment, for example, currently needing to carry out base station or the cluster application server of group service data transmission, all
The reception address notification message sent by core net will be received, the reception address notification message is for notifying the network equipment to realize
It sends destination address new corresponding to data.
Step 250, the destination address itself progress group service data transmission stored is purpose address mark.
After the network equipment receives reception address notification message, extracted in group service by receiving in the notification message of address
Data carry out transmitting corresponding destination address mark.
Step 270, it is identified according to the destination address of replacement and carries out path bypass, obtained itself and carry out group service data biography
Defeated channel.
The network equipment establishes the channel between another network equipment, channel bypass according to the destination address mark of replacement
Core net, so that the group service data transmission thus carried out does not need can to complete via core net yet.
After passage path bypass completes the foundation in channel, the network equipment can pass through the channel transfer group service
Data.
By process as described above, realize that each network equipment of group service will realize each group service by the channel
The uplink and downlink transfer of data, the group service data transmission by-pass between each network equipment fall core net.
Further, in the present embodiment, address mark includes IP address and TEID, then the detailed process of step 270
Are as follows: the GTP transmission module of the network equipment is set according to the obtained network address of replacement and tunnel endpoint identifier with target network
The standby channel for establishing group service transmission.
For the network equipment as cluster application server, needs to extend inside it and realizes GTP transmission module,
So that it has GTP transfer function.
For the network equipment as base station, since itself just has GTP transfer function, can collect
After group's application server internal extended realizes GTP transmission module, the relatively core between cluster application server is directly established
The bypass channel of heart net, and then data are exchanged in this bypass channel, data transmission is accelerated, in particular so that audio data,
Even video data, which is able to carry out, faster transmits.
This destination network device is the receiving end that present networks equipment carries out company-data transmission, and present networks equipment conduct
Source network device then can be considered transmitting terminal, to realize that IP address and the TEID of Path Setup are that destination network device institute is right
The address mark answered.
Further, in another embodiment, address mark includes IP address, the detailed process of the step 250 are as follows: logical
Network address translation (Network Address Translation, abbreviation NAT) module in the network equipment is crossed under core net
The IP address of hair is converted, and the destination address of storage is replaced with the address after conversion and is identified.
Each network device internal for carrying out the transmission of group service data extends NAT module, and the NAT module is to carry out
The conversion of IP address a, so that IP address can carry out the access of group service data.
Specifically, in the realization of group service, base station can request after having carried out network address translation
Data in cluster application server.
Another aspect, it, can be after having carried out network address translation to base station for cluster application server
Carry out network access, so realize each terminal is carried out to group service server by base station in group service audio data,
The transmission of video data etc..
Therefore, it is impossible to be base station or cluster application server, after reception obtains receiving address notification message, all
Original data transfer address is replaced after being converted to the IP address received in the notification message of address, and is stored.
Further, in the present embodiment, the detailed process of the step 270 are as follows:
The network address of destination network device is obtained by the destination address stored after the conversion replacement of NAT module, passes through net
Network address and destination network device establish the channel of group service data transmission.
Any network equipment is due to having network access functions in the realization of group service, inside realize NAT mould
Block, when needing to carry out the transmission of group service data, the network equipment parses IP corresponding to destination network device by NAT module
Address, and then the channel between destination network device is established according to the address mark after conversion, which is group service number
According to the IP tunnel of transmission.
The solution of the present invention is elaborated below with reference to a specific embodiment.In the embodiment, as shown in figure 5,
Cluster application server 310 includes video server 311, recording service device 313 and recording server 315, and each terminal 330 is

Row transmission and downlink transfer with the 310 biography data on cluster application server and obtain the number in cluster application server 310
According to.
In the transmission of this group service data, as shown in fig. 6, under the control of core net 370, establish eNB350 ←
→ core net 370 ← → cluster application server 310 link, so that being located at any terminal of eNB350 coverage area
330 are able to carry out the transmission of group service data with cluster application server 310 by eNB350.
However, on this basis, bypass core net 370 will realize that group service data accelerate transmission, it is based on
This obtains the corresponding address mark of eNB350 and 310 institute of cluster application server under the control of core net 370, according to
Address mark is respectively reception corresponding to reception address notification message and cluster application server 310 corresponding to eNB350
Address notification message.
Wherein, the address label of cluster application server 310 is contained in reception address notification message corresponding to eNB350
Know, the address mark of eNB350 is contained in reception address notification message corresponding to cluster application server 310.
As shown in fig. 6, core net will execute step 410 and 430, respectively to eNB350 and cluster application server 310
Address notification message is transmitted and received, and receives corresponding response.
The uplink destination address in the downlink destination address and eNB350 in cluster application server 310 is replaced, cluster is answered
With path bypass is carried out between server 310 and eNB350, as shown in fig. 7, eNB350 and cluster application server 310 bypass
Core net 370 establishes bypass channel, and the bypass channel established realizes fast between eNB350 and cluster application server 310
Speed transmission.
Wherein, address mark can be IP address, be also possible to IP address and TEID.
If address that core net 370 is mutually transmitted between eNB350 and cluster application server 310 mark is IP
Location and TEID, then GTP transmission module, reception transmitted by core net 370 are realized in extension first in cluster application server 310
Address notification message carries IP address and TEID, and program process when related is as shown in figure 8, and establish as shown in Figure 9
The channel GTP.
Another aspect, if the address that core net 37 is mutually transmitted between eNB350 and cluster application server 310
Mark is IP address, then is extended in eNB350 and 310 two sides of cluster application server respectively first and realize NAT module, with docking
The network packet received is converted.
As shown in Figure 10, IP address is carried in reception address notification message transmitted by core net 370, it is related detailed
Program process is as shown in Figure 10 when thin, and obtains the IP tunnel for having bypassed core net 370 as shown in figure 11.
It should be noted that core net 370 as shown in Figure 5 actually includes eXGW371, TMF373 (cluster media net
Member), eMME375, TCF377 (clustered control network element) and eHSS379 this five logic entities, and eXGW371 and TMF373 phase
