Description

Negotiation method and determination method of terminal capability and terminal

technical field

The present invention relates to the field of multimedia communication, in particular to a method for negotiating and determining terminal capabilities and a terminal.

Background technique

With the rapid development of wireless broadband networks and intelligent terminals, the development of multimedia communication-related services is getting faster and faster. At present, multimedia communication first needs to negotiate terminal capabilities, the purpose of which is to enable the communication parties to understand the capabilities of the multimedia (such as audio and video) supported by the other end, so as to ensure that the communication parties can encode and decode normally. However, due to various reasons, when the communication parties negotiate their capabilities, they only explain their respective capabilities, such as through SDP (Session Description Protocol, Session Description Protocol) files or UA Profile (User Agent files) to let the other party Or the server knows the capabilities it supports. In the era of feature phones, due to the poor processing capabilities of feature phones, the terminal capability itself has a large deviation in the ability to support multimedia communication services. Therefore, a simple judgment on the capabilities of the peer terminal can solve the main contradiction. However, with the rapid development of intelligent terminals, the limitation of the terminal itself on multimedia communication capabilities has been greatly weakened. The main issue is whether the attribute support of multimedia formats can be understood by each other, and this format support has also been greatly generalized, making capability negotiation To a certain extent, it no longer belongs to the main contradiction.

Although the wireless broadband network has been greatly developed, compared with the user's demand for resources, it is still far from meeting the user's expectations. At this time, the main contradiction in multimedia communication has become the network resources used by both communication parties. Whether the state can meet the requirements of both communication parties. In the existing technology, after the two parties establish a connection, they will feed back some network performance data to the opposite end; after receiving it, if the opposite end finds that it cannot meet the needs of the local end, adjust the relevant parameters of the local end or disconnect the link with the opposite end To re-link, this operation mode is cumbersome, which is not conducive to saving system signaling overhead.

In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

In this embodiment, a method for negotiating a terminal capability includes:

The terminal sends its own statistical network performance data to the communication peer;

After receiving the network performance data sent by the communication peer, combine the capabilities supported by itself to determine the capabilities applicable to the communication between the two parties.

In this embodiment, the above network performance data is used to support multimedia terminals as capability negotiation reference data during communication, so that both communicating parties can make fast and correct resource judgments and select the correct communication protocol.

In actual implementation, the user can pre-set the network performance data to be counted on the terminal, such as TCP (Transmission Control Protocol, Transmission Control Protocol) data, UDP (User Datagram Protocol, User Datagram Protocol) data, etc. As shown in Figure 1, the network performance data collected by the terminal may include: allocated effective bandwidth, remaining available bandwidth, TCP data packet loss rate, TCP data delay time, UDP data packet loss rate, and UDP data delay time. One or any combination; when the terminal needs to use the wireless channel to initiate the capability negotiation of related services, it can directly add the calculated network performance data to the capability negotiation data and send it to the other party.

Every time the statistics of network performance data are performed, the terminal will update and save the calculated network performance data, which can be saved in memory, local storage files, or other network elements in the network. superior.

In this embodiment, a method for determining a terminal capability includes:

The terminal performs statistics on network performance data;

According to the network performance data collected by itself, combined with its own supporting capabilities, determine the capabilities applicable to itself. Wherein, the network performance data includes: based on TCP data or UDP data.

Preferably, the network performance data includes any one or any combination of allocated effective bandwidth, remaining available bandwidth, TCP data packet loss rate, TCP data delay time, UDP data packet loss rate, and UDP data delay time.

The above-mentioned terminal stores the network performance data collected by itself in the internal memory of the terminal, in a local storage file, or in other network elements in the network.

The present invention will be further described below with two application examples.

Application example 1:

A method for determining terminal capabilities, which is applied in the process of using Internet services by terminals through Internet applications, including:

Step 1: After the terminal detects that the Internet application is started, it obtains the network performance data collected 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 makes corresponding judgments based on the obtained network performance data, and selects resources suitable for the above-mentioned Internet applications to operate; for example: when browsing web pages through a browser, if the obtained network performance data shows that the available bandwidth is relatively If the data is small, the data packet loss rate is large, or the data delay is large, the browser can automatically change to the no-image mode to reduce the consumption of bandwidth and reduce the acquisition of image resources that are likely to cause large delays. It mainly displays relevant text information. Satisfy the user's acquisition of information; if the obtained network performance data shows that 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 Internet TV, can be used to provide better resources to meet the needs of users; another example is for e-mail Internet applications, when the network performance data is good, the refresh frequency can be increased, and when the network performance data is poor, the refresh frequency can be lowered; There are many similar applications, which are not listed here.

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

Application example 2:

A method for negotiating terminal capabilities, which is applied in the process of network video communication between two terminals, as shown in Figure 2, including:

Step 1. After the terminal detects that the Internet video application is started, the specific process of obtaining the network performance data collected by the device is as described in Application Example 1, and will not be repeated here.

Step 2. The terminal organizes its own SDP file and sends the SDP file to the communication peer:

Such as adding network performance data information in the SDP file:

a = NetPerformance: availableBandWidth: 1M PacketLossRate0.1PacketDelay0.5s

...Other media information in SDP is ignored and not written

That is, the network performance data of the local end is provided to the communication peer through the SDP file, and the peer end can know the network performance status of the local end from these data, so that a related resource with media attributes that can match the network performance status can be selected as the communication between the two parties benchmark.

As mentioned above, when the peer end receives the SDP file sent by the local end, it can be judged by the network performance data of the local end carried in it. Even if both parties support video communication with a bandwidth of 2M, due to the bandwidth limitation of the local end, the two parties can negotiate to use it. The 1M bandwidth video communication avoids the occurrence of poor video quality caused by both sides supporting 2M bandwidth codec video communication.

To sum up, the present invention focuses on statistics of network performance data, and uses the statistical network performance data to make a judgment that is beneficial to the normal use of the application.
