Fig. 1 is the flow chart of an embodiment of the method for data bypass of the present invention, and as shown in Figure 1, the identification method of the data bypass of the present embodiment, based on AP, comprising:
S11, receives the packet carrying out data bypass of UE;
May there is multiple UE, AP to need to carry out data bypass to the data of this multiple UE under an AP, now, AP will receive packet that each UE in the plurality of UE sends, that need to carry out bypass simultaneously.
S12, adds the identification information of described UE in the packet of described reception;
Described identification information refers to the information that can identify UE uniquely, can identify described UE uniquely by described identification information.
Particularly, the identification information of described UE can be added in the Optional Field of packet header.Described identification information, for example, can be IMSI (International Mobile SubscriberIdentification Number, international mobile subscriber identity), MAC (Medium AccessControl, medium access control) address etc.
S13, is added with the described packet of the identification information of described UE, to make described gateway according to the identification information of the described UE carried in described packet, identifies described packet and come from described UE to gateway described in sending.
The present embodiment AP receive UE carry out the packet of data bypass after, identification information corresponding to described UE is correspondingly added in received packet, described UE is identified uniquely by this identification information, and described in sending to described gateway, be added with the described packet of the identification information of described UE, so, described gateway can identify packet from described UE according to the identification information in packet, thus, the flow of described UE correspondingly can be added up, corresponding charging according to the packet of described UE.Similarly, which UE described gateway, when receiving the packet that multiple UE sends, also according to the identification information in each packet, can correspondingly identify packet from, thus realizes each UE statistic flow and charging respectively.
Corresponding with preceding method, the embodiment of the present invention also provides a kind of identification method of data bypass, and based on gateway, such as BRAS (Broadband Remote Access Server, Broadband Remote Access Server), as shown in Figure 2, comprising:
S21, receives the packet carrying out data bypass of UE, is added with the identification information of described UE in described packet;
S22, according to the identification information of the described UE carried in described packet, identifies described packet and comes from described UE.
The present embodiment gateway receive UE carry out the packet of data bypass after, owing to being added with identification information corresponding to described UE in received packet, this identification information identifies described UE uniquely, so, described gateway can identify packet from described UE according to the identification information in packet, thus, the flow of described UE can correspondingly be added up according to the packet of described UE, corresponding charging.Similarly, which UE described gateway, when receiving the packet that multiple UE sends, also according to the identification information in each packet, can correspondingly identify packet from, thus realizes each UE statistic flow and charging respectively.
For a better understanding of the present invention, for several specific embodiment, the present invention is further described below.Also notably, embodiment cited is below a part of embodiment of the present invention, and those skilled in the art are by content of the present invention, and can be easy to expect other embodiments, they all within the scope of the invention.
Fig. 3 is the flow chart of a specific embodiment of the identification method of data bypass of the present invention.As shown in Figure 3, the present embodiment comprises:
S31, AP receive the IP packet carrying out data bypass of a UE.
S32, described AP add the IMSI information (identification information) of a UE in the Optional Field of described IP packet header.
IMSI information by a UE writes the Optional Field in described packet, makes the IMSI information carrying a UE in the Optional Field of described IP packet.Because IMSI is in the world for uniquely identifying the number that a mobile subscriber distributes, therefore a UE can be identified with IMSI uniquely as the identification information of a UE.
S33, described AP, after identifying a UE by IMSI information, send the IP packet carrying out data bypass of a UE, include the IMSI information of a UE in described IP packet to gateway.
S34, described gateway receives the IP packet carrying out data bypass of the UE that described AP sends.
S35, described gateway, according to the identification information carried in described IP packet, identifies described packet and comes from a UE.
Specifically, the IP packet of described gateway to a UE is resolved, and knows the IMSI information in Optional Field in described IP packet, and the IMSI information of carrying in IP packet according to a UE, identify the packet of described bypass from a UE.Like this, gateway just can add up the flow of this UE, and then realizes the charging to this UE.
Certainly, for the IP packet carrying out data bypass that other UE send, AP and gateway also repeat said process, to realize flowing quantitative statistics and charging to other UE.
When UE moves between different AP, these different AP carry out the IMSI information of adding described UE in the Optional Field of the IP packet of data bypass also at described UE, thus, gateway equally can according to IMSI information identification data from subscriber equipment, and then add up the flow of this subscriber equipment and carry out corresponding charging.
In the present embodiment, AP receive UE carry out the packet of data bypass after, IMSI information corresponding to described UE is added in received packet, identify described UE uniquely by this IMSI information, and be added with the described packet of the IMSI information of described UE described in sending to gateway, so, gateway can identify packet from described UE according to the IMSI information in packet, thus, the flow of described UE can correspondingly be added up according to the packet of described UE, corresponding charging.Correspondingly, gateway, when receiving the packet that multiple UE sends, also according to the IMSI information in each packet, can correspondingly identify the packet of each UE, thus realizes each UE statistic flow and charging respectively.
It should be noted that, in the present embodiment, IMSI information is added on the Optional Field of packet header, but the present embodiment is not limited thereto, and IMSI information also can be added to other positions of IP packet.
Fig. 4 is the flow chart of another specific embodiment of identification method of data bypass of the present invention.As shown in Figure 4, the present embodiment comprises:
S41, AP receive the IP packet carrying out data bypass of a UE.
S42, described AP determine the port list calculating parameter that a UE is corresponding.
Specifically, AP, after the IP packet receiving a UE, can be a UE and distributes a port list calculating parameter.Such as, being that a UE distributes a port list calculating parameter by the allocation rule preset, can also be that a UE distributes port list calculating parameter, such as Random assignment by alternate manner certainly.It should be noted that in the present embodiment, port list calculating parameter will be used for identifying UE, therefore, need to ensure that the port list calculating parameter for each UE distribution is different.Particularly, described port list calculating parameter is AP is the numerical value that a UE distributes, and for example, this numerical value can be the numbering of AP to its each UE lower, and certainly also can be the sequence number of other purposes, the present invention is not construed as limiting this.
S43, described AP according to the port list calculating parameter of the described UE determined, determine a UE can port list.
Particularly, AP by following formula determine described UE can port list:
A+n×N+(k-1)
Wherein, A is the port number taken, and N is the sum of UE, k is that in S42 step, AP is the port list calculating parameter that a UE determines, n be a UE can port sequence number, n is integer, and n=0,1... (M-A)/N, M is port sum, occurrence can be 65535.
For example, the port number taken when system is 2048, i.e. A=2048, UE under an AP adds up to 10, i.e. N=10, port list calculating parameter is 2, namely during k=2, under this AP each UE can port number be (M-A)/N=(65535-2048)/10=6348, namely each UE can with 6348 ports.
Port list calculating parameter is the port list of the UE of 2:
During n=0,2048+0 × 10+ (2-1)=2049;
During n=1,2048+1 × 10+ (2-1)=2059;
During n=6437,2048+6347 × 10+ (2-1)=65519
The like, the value difference UE sum of two often adjacent ports of same UE, is namely separated by 10.
A kind of method according to port list calculating parameter determination port list more than just listed by way of example, also can adopt additive method to determine port list.Such as, when all UE under AP add up to 10, each UE is desirable continuous print 6348 ports also.
S44, described AP a received UE carry out add port list calculating parameter (identification information) corresponding to the described UE determined in the Optional Field of the IP packet header of data bypass.
In the present embodiment, be the identification information of the port list calculating parameter determined of a UE as a UE using described AP.
S45, at least one port in the port list determined described in described AP passes through will be added with the IP data packet transmission of the port list calculating parameter of a UE to gateway.
S46, described gateway receives the IP packet carrying out data bypass of the UE that described AP sends, and carries the port list calculating parameter that a UE is corresponding in described IP packet.
S47, described gateway, according to the port list calculating parameter comprised in described IP packet, determines the port list of a UE according to the computational methods identical with AP, identify and use the packet of at least one port in described port list to come from a UE.
So, described gateway is identical with the port list that described AP determines for same UE, again due to each UE can port list not identical, thus, described gateway can count the flow that the flow of port list that each UE uses can determine each UE respectively, and then corresponding charging.
Should be noted, in the present embodiment, for making AP identical according to the identical determined port list of port list calculating parameter with gateway, AP need configure identical computational methods with gateway, thus calculate the available port list of UE according to port list calculating parameter, and then by UE can port list realize flowing quantitative statistics and charging to this UE.
Obviously, for the IP packet carrying out data bypass that other UE send, AP and gateway also repeat said process, to realize flowing quantitative statistics and charging to other UE.
In the present embodiment, AP receive UE carry out the packet of data bypass after, the port list calculating parameter that described UE is corresponding is correspondingly added in received packet, described UE is identified uniquely by this parameter, and described in sending to gateway, be added with the described packet of the port list calculating parameter of described UE, so, gateway can according to the corresponding port list determining described UE of port list calculating parameter, and then identifiable design goes out the packet that sent by least one port in the described port list determined from described UE, thus, the flow of described UE correspondingly can be added up according to the port list of described UE, corresponding charging.Correspondingly, gateway, when receiving the packet that multiple UE sends, also according to the port list calculating parameter in each packet, can correspondingly identify the packet of each UE, thus realizes each UE statistic flow and charging respectively.
