Description

Terminal capability negotiation method, determination method and terminal

Technical field

Background technique

With the rapid development of wireless broadband networks and smart terminals, the development of multimedia communication-related services is growing faster. At present, multimedia communication first needs to negotiate terminal capabilities. The purpose is to enable the two parties to understand each other's capabilities of multimedia (such as audio and video) supported by the peer to ensure that both parties can properly encode and decode. However, for various reasons, when the communication parties conduct capability negotiation, they only explain their respective capabilities, such as SDP (Session Description Protocol) file or UA Profile (user agent file). Or the server knows what capabilities it supports. In the era of feature phones, due to the poor processing capabilities of feature phones, the ability of terminal capabilities to support multimedia communication services varies greatly. Therefore, simply making a simple judgment on the peer capabilities can solve the main contradiction. However, with the rapid development of intelligent terminals, the limitations of the terminal itself on multimedia communication capabilities are greatly weakened, mainly whether the support for the attributes of the multimedia format can be mutually understood, and the support of this format is also greatly universalized, so that the capability negotiation To a certain extent, it is no longer a major contradiction.

Although the wireless broadband network has been greatly developed, compared with the user's demand for resources, it is far from the user's expectation. At this time, the main contradiction of multimedia communication becomes the network resources used by the communication parties. Whether the status can meet the requirements of both parties. In the prior art, after the communication parties establish a connection, some network performance data is fed back to the peer end; if the peer end receives, if it finds that the local end requirement cannot be met, the relevant parameters of the local end are adjusted or broken with the opposite end. In the case of re-linking, this operation is cumbersome and is not conducive to saving system signaling overhead.

Step 1: After detecting that the Internet application is started, the terminal obtains the network performance data counted by the device, that is, reads the network performance data from the memory, the local storage file, or the network accordingly; Step 2: The terminal obtains according to the obtained The network performance data is judged accordingly, and the resources suitable for the above Internet application are selected for operation; for example: when browsing the webpage through the browser, if the obtained network performance data shows that the available bandwidth is small, the data packet loss rate is large or The data delay is large, The browser can be automatically changed to the no-picture mode, reducing the consumption of bandwidth, reducing the acquisition of image resources that are likely to cause large delays, mainly displaying related text information, and satisfying the user's acquisition of information; if the obtained network performance data If the current available bandwidth is large, the network packet loss rate is small, or the packet delay time is short, some multimedia resources, such as network TV, can be used to provide better resources to meet the needs of users; for example, for the Internet of mail Application, when the network performance data is good, the refresh frequency can be improved. When the network performance data is poor, the refresh frequency is lowered. There are many similar applications, not enumerated here.

In summary, using network performance data can increase application flexibility.

a=NetPerformance: availableBandWidth: 1M PacketLossRate 0.1 PacketDelay 0.5s

... Other media information in the SDP ignores the data. The data performance status of the local end can be known, so that a related resource of the media attribute that can match the network performance status can be selected as the reference for the communication between the two parties.

As described above, after receiving the SDP file sent by the local end, the peer end judges that the video performance of the local end carried by the peer end, even if both sides support the video communication of the 2M bandwidth, the two parties can negotiate the use due to the bandwidth limitation of the local end. The video communication of 1M bandwidth avoids the situation that the video quality is poor due to the video communication of the code rate codec of both sides supporting 2M bandwidth.
