Embodiment Construction

[0057] The core idea of ​​the present invention is that the WPI module in the AP judges the type of data that needs to be encapsulated into the MPDU before encapsulating the MPDU (MAC Protocol Data Unit, Media Access Control Protocol Data Unit), if it is a real-time data service The control signaling message is encrypted and then encapsulated in the data (PDU) field of the MPDU and sent to the mobile terminal; if it is an audio and video data message for real-time data services, it is not encrypted and is directly encapsulated in the MPDU in plain text sent to the mobile terminal in the data (PDU) field.

[0058] The MPDU encapsulation structure of WPI is as follows figure 2 shown, where:

[0059] The length of the MAC header field is 24 bytes or 30 bytes;

[0060] The length of the session key index field is 1 byte, indicating the value of USKID (unicast session key index) or MSKID (multicast session key index) or STAKeyID (inter-station key index), that is, the value used...

Abstract

The invention discloses a method for implementing real-time data service, a real-time data service system and a mobile terminal. The method comprises the steps: when the mobile terminal interacts with an access point (AP) of the real-time data business system and an authentication server and completes the certificate identification process of a WAI protocol, the mobile terminal negotiates with the AP to obtain a session key K; the mobile terminal implements the interaction for the control signaling message of real-time data service with a real-time data service server of the real-time data service system through the AP so as to start and control the real-time data service; after the real-time data service is started, the real-time data service server sends out audio and video data messages of the real-time data service to the mobile terminal through the AP, wherein the session key K is used between the mobile terminal and the AP for encrypting and packaging the control signaling message in a medium access control protocol data unit (MPDU) for transmission; and the AP packages at least one audio and video data message in the MPDU by a way of clear text and then sends out the message to the mobile terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a real-time data service realization method, a real-time data service system and a mobile terminal. Background technique [0002] With the maturity of the 3G network and the improvement of the performance of the mobile terminal, it has become possible to use the mobile terminal to perform real-time data services. For example, a user can use a mobile phone TV client to watch mobile TV, use a mobile streaming media client to order audio and video programs or watch audio and video live programs. The development of real-time data services will effectively improve the experience of mobile phone users in the 3G era, and the operation based on real-time data services will also become the focus and focus of operators in the 3G era. [0003] Real-time data services include: mobile TV, video on demand, live video, etc. After the real-time data service server is deployed in the wireless local ar...
