Embodiment 1

[0061] The embodiment of the present invention provides an authentication message sending method when the interactive message body between BS, AGW, and AAA server is long during the authentication process, which can neither affect the transmission of the shorter message nor ensure the reliability of the longer message transmission, including the following:

[0062] R6 port message AR_EAP_Transfer, for example, the direction is BS->AGW, then the BS needs to confirm whether the encapsulated message is longer to determine whether to use the TCP connection to transmit the message, and whether it is longer is determined according to the MTU. This value needs to be set in the background. For example, if the value is set to 1000, if the sum of the payload length + UDP header length + IP header length of the AR_EAP_Transfer message exceeds this value, TCP transmission is required. And a TCP channel is established between the BS and the AGW, and the message is transmitted through the c...

Embodiment 2

[0067] The background network management part of the base station, AGW, and AAA server adds a parameter EAP Message MTU as the limit value of whether the authentication message is transmitted using the TCP connection.

[0068] Add an authentication message comparison, classification and channel establishment module to the front-end software of the base station. Its main functions are as follows: figure 2 Shown:

[0069] Step S202, comparing the AR_EAP_Transfer message exchanged between the BS and the AGW with the EAP Message MTU to determine whether it is greater than the EAP Message MTU, if yes, execute step S204, if not, execute step S210;

[0070] Step S204, if the length of the message is larger, the module checks whether there is already a TCP connection between the AGW, if so, execute step S208, if not, execute steps S206 and S208;

[0071] Step S206, if not, the BS actively initiates a TCP connection to the AGW through the module, that is, the BS acts as the client an...

Abstract

The invention discloses a message transmission method and device. The message transmission method comprises the following steps: judging whether the length of the message to be transmitted is more than the preset EAP Message MTU value, and transmitting the message to be transmitted by adopting the TCP (transmission control protocol) transmission form if the length of the message to be transmitted is more than the preset EAP Message MTU value. The message transmission method and device solve the problem in the prior that the UDp (user datagram protocol) connection authentication process can lead to low authentication success rate.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message transmission method and device. Background technique [0002] The architecture of the Mobile Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access) network includes at least a mobile user terminal (MSS, Mobile Service Subscribe), a BS (BS, Base Station), an access gateway (ASN-GW, ASN Access Gateway), core network (CSN, Connection Service Network) and application service provider (ASP, Application Service Provider) network. Wherein, the MSS is a mobile user equipment, and the user uses the equipment to access the WiMAX network. The BS handles data on the air interface (R1 interface) and the R6 interface with the ASN-GW. The AGW processes the R6 interface data with the BS and the data with the CSN. Both BS and ASN-GW are part of ASN, and CSN consists of router, authentication, authorization, accounting (AAA, Authenti...
