Embodiment
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment mono-
The embodiment of the present invention one provides a kind of transmission method of data, application scenarios schematic diagram taking Fig. 2 as the embodiment of the present invention, the method can be applied to and comprise terminal equipment, MiFi equipment, Cellular Networks access device (as eNodeB/NodeB etc.), core network packet-domain gateway (as P-GW/GGSN etc.), AC/BRAS, certificate server (as aaa server/Radius server etc.), HLR(Home Location Register, attaching position register, does not embody in figure) and the network of business platform in.
In the verification process of the embodiment of the present invention, specifically include but not limited to the verification process of terminal equipment and the verification process of MiFi equipment; Wherein:
In the verification process of terminal equipment, its Signalling exchange is through MiFi equipment, Cellular Networks access device, core network packet-domain gateway, AC/BRAS and certificate server; After terminal device authentication completes, certificate server can be notified the IP address of terminal equipment and corresponding subscriber identity information (as the information such as MSISDN and IMSI) to core network packet-domain gateway; Under this execution mode, core network packet-domain gateway can receive notification message from certificate server (for follow-up differentiation convenient, this notification message is the second notification message), and the IP address of carried terminal equipment and corresponding subscriber identity information in this second notification message; Certainly,, after terminal device authentication completes, certificate server also can not notified the IP address of terminal equipment and corresponding subscriber identity information to core network packet-domain gateway.
MiFi device interior is inserted with (U) SIM(Subscriber Identity Module, Subscriber Identity Module), it is equivalent to a terminal equipment of Cellular Networks, and therefore MiFi equipment also needs to carry out verification process; In the verification process of MiFi equipment, its Signalling exchange is through Cellular Networks access device, core network packet-domain gateway, AC/BRAS and attaching position register; After MiFi device authentication completes, attaching position register can be notified the contextual information of the session management of MiFi equipment to core network packet-domain gateway; Under this execution mode, core network packet-domain gateway can receive that notification message from attaching position register is (in order to distinguish conveniently, this notification message is the first notification message), and in this first notification message, carry the contextual information of the session management of MiFi equipment; Wherein, the contextual information of this MiFi equipment includes but not limited to IP address and the identity information (as the information such as MSISDN and IMSI) of MiFi equipment.
In the embodiment of the present invention, in the contextual information of the session management of MiFi equipment, can also comprise user's switch-in attribute information of MiFi equipment, this user's switch-in attribute information includes but not limited to APN(Access Point Name, access point) information and QoS(Quality of Service, service quality) information etc.
As shown in Figure 3, the transmission method of these data comprises the following steps:
In the embodiment of the present invention, between MiFi equipment and AC/BRAS by the point control of CAPWAP(Controlling and Provisioning of Wireless Access Point wireless access and supply agreement) tunnel is connected, and this CAPWAP tunnel need to pass through core network packet-domain gateway; Therefore, in the time sending to data by MiFi equipment, MiFi equipment need to utilize CAPWAP tunnel to send this data to terminal equipment (its IP address is distributed by AC/BRAS), and these data can be passed through core network packet-domain gateway; On core network packet-domain gateway, in the time having the flow of MiFi equipment to arrive this equipment, core network packet-domain gateway is tackled opening to this flow; Processed by core network packet-domain gateway for business datum; For non-traffic signaling (as control signal, certification signaling etc.), core network packet-domain gateway forwards it to AC/BRAS.
In the embodiment of the present invention, core network packet-domain gateway comprises the processing procedure of data: core network packet-domain gateway is distinguished specified type data and non-designated categorical data; Wherein, these specified type data include but not limited to own business datum (as the data based on Fetion business); This non-designated categorical data comprises but is not limited to Internet data; For specified type data, this core network packet-domain gateway need to be carried out subsequent step 302; For non-designated categorical data (as Internet data), this core network packet-domain net to the Internet, repeats no more Internet data retransmission in this process embodiment of the present invention.
In the embodiment of the present invention, core network packet-domain gateway records the corresponding relation between the contextual information of terminal equipment and the contextual information of MiFi equipment, specifically comprises: core network packet-domain gateway judges whether this equipment has subscriber identity information corresponding to terminal device IP address carrying in data; If there is subscriber identity information, core network packet-domain gateway records the corresponding relation between the contextual information of terminal equipment and the contextual information of MiFi equipment; If there is no subscriber identity information, core network packet-domain gateway obtains subscriber identity information corresponding to terminal device IP address, and records the corresponding relation between the contextual information of terminal equipment and the contextual information of MiFi equipment.
