Embodiment 1
[0030] Such as figure 1 As shown, it is a schematic diagram of a method for data transmission in Embodiment 1 of the present invention, and the application scenario of each embodiment of the present invention is a PMIPv6 protocol system.
[0031] The scheme of embodiment one comprises the following steps:
[0032] Step 101: the first network element sends a negotiation request to the second network element, and the negotiation request carries the transport layer protocol type supported by the first network element.
[0033] In this embodiment, the first network element is MAG or LMA, and the second network element is MAG or LMA. Therefore, the transmission process in this embodiment can be performed between MAG and LMA, or between LMA and LMA. It can also be performed between MAG and MAG.
[0034] The transport layer protocols in this embodiment include but are not limited to the following protocols: Stream Control Transmission Protocol (SCTP), Transmission Control Protocol ...
Embodiment 2
[0055] Embodiment 2 of the present invention illustrates the implementation process of the solution of Embodiment 1 through a specific example. It is assumed that the process of data transmission between the MAG and the LMA in Embodiment 2 is as follows: figure 2 As shown, it is a schematic diagram of the format of the transport layer negotiation option defined in the extended option of the PBU / PBA message. The transport layer negotiated option is added to the extended option (Mobility Options) of the PBU / PBA message in the PMIPv6 protocol.
[0056] The meanings of each field of the transport layer negotiation option are:
[0057] Type: Indicates the option type, and the specific value is to be determined. In the present invention, the value of Type TBD indicates the transport layer negotiation option.
[0058] Length: Indicates the length of the option, and its content is the number of bytes. The number of bytes indicated by the value of Length does not include the number of...
Embodiment 3
[0086] Embodiment 3 of the present invention also provides a data transmission system, such as Figure 9 As shown, applied to a proxy mobile IPv6 system, the data transmission system includes a first network element 11 and a second network element 12, wherein: the first network element 11 is used to send a negotiation request to the second network element 12, the The negotiation request carries the transport layer protocol type supported by the first network element; the second network element 12 is used to select the transport layer protocol type supported by itself from the received transport layer protocol types, and select the selected transport layer protocol type through the negotiation response message The transport layer protocol type is returned to the first network element, and data transmission is performed with the first network element through the transport layer protocol corresponding to the selected transport layer protocol type.
[0087]The second network eleme...
