The invention discloses a video source determination method comprising the steps of when the condition that a first video source of a currently playing video is in an abnormal state is monitored, recording a time length of the first video source in the abnormal state, and determining a first time length; judging whether the time length of the first video source in the abnormal state is more than the first time length; when the time length of the abnormal state is more than the first time length, determining a second video source based on a preset changing strategy; and playing the currently playing video based on the second video source. The embodiment of the invention provides a video source determination device and a computer readable storage medium.

A QoS guarantee system of a 5G satellite convergence network comprises a resource cache and flow control module, and is characterized in that services in the network are classified, and data flows ofdifferent services are separated; a network monitoring module can set a probe at a network entrance of the 5G satellite convergence network, the probe is used for monitoring network flow of differentservices to obtain network delay, jitter and packet loss rates of the different services, and the network delay, jitter and packet loss rates are sent to the evaluation and decision module; the evaluation and decision module is used for obtaining an MOS score of QoS according to the network delay, jitter and packet loss rates of different services, and determining a network adjustment strategy anda network adjustment strategy according to the MOS score by utilizing a pre-stored corresponding relationship between the MOS score and the network adjustment strategy, including processing of data packets in the network, routing decision and network configuration; and the network control module is used for adjusting and controlling the network according to the network adjustment strategy. According to the invention, non-blocking stable communication capability is realized, and diversified application services are provided.

The invention provides an energy-saving and anti-interference speed cracking method in a cognitive heterogeneous network, which utilizes equivalent deformation of an energy efficiency equation and a cooperative game Nash axiom to carry out iteration on a transmission speed of each sub-network to obtain the optimal speed with high energy efficiency and small interference. A plurality of the sub networks are used for carrying out parallel transmission and parts of carriers of a base station do not need to be closed or blocked so that the base station can work normally. According to the method disclosed by the invention, the normal work of the base station is not changed and the quality of user experiences is guaranteed; not only can small interference be realized, namely the spectrum efficiency is high, but also energy-saving effects are realized, and the condition that iteration and convergence can be carried out in limited times can be strictly ensured.

The invention belongs to the field of QoE and network resource management of video services, in particular to a statistical analysis-based QoE-QoS parameter mapping method for a session video service,which comprises the following steps of firstly, capturing a video data stream in a required network through network packet analysis software in data acquisition, and storing the captured original data stream in a standard text format; secondly, carrying out a large amount of flow statistical characteristic calculation; then, calculating an MOS value according to the standard of the internationaltelecom alliance; selecting parameters such as packet loss rate, transmission rate, delay jitter and the like to perform graph drawing and formula fitting, and obtaining an optimal parameter suggestion index according to a result; and finally substituting the given reference value into the model for calculation, and carrying out statistics on the probability of falling in a preset MOS value rangefor verification. On the premise of guaranteeing the user experience quality, the network resources can be distributed more reasonably and effectively, and the resource waste caused by the excessive distribution of the network resources to the users with the user experience quality meeting the requirement is avoided.

The invention discloses a D2D network setup method based on scalable video streaming user quality of experience. D2D communication is organized into a spanning tree for transmitting scalable adaptivevideo streaming. In an initialization phase, a D2D network is organized into the spanning tree with acceptable user quality of experience and fairness. In a management phase, the service continuity isrespectively maintained under the condition that different devices arrive or depart. On the basis of a local search technology, according to the scheme, data structures of disjoint sets and the localsearch technology are combined, the reachable operation time is O [mn alpha (m, n)]. According to the scheme, the capacity of a service network can be improved, the quality of experience, fairness and continuity of the service are ensured, and a great number of users can be supported.

The invention provides a method and device for controlling a subscriber strategy, relating to the communication field. The method comprises the step that: a strategy server obtains information related to a subscriber from an authentification, authorization and accounting (AAA) server, and conducts a follow-up strategy control according to the obtained information related to the subscriber.

The invention provides a video peer-to-peer flow exchange method, system and device, which are characterized in that each server node is set to adopt a peer-to-peer network structure, hierarchy is not distinguished, local storage of each server node is gathered into a virtual shared storage, and decentration is realized. The full links between the server nodes and the user nodes are set to communicate by adopting a real-time audio protocol, so that the time delay and the calculation cost of the distribution network are reduced. A subscription push mechanism is established, when a user requests video data, a preset user perception guarantee algorithm is adopted to calculate a correlation score between a current user node and a user node which has obtained specified video data, and the user node with relatively high correlation is selected as an associated user node for subscription. And the associated user node directly pushes the video data to the current user node, so that the network delay is greatly reduced, and the user experience quality is guaranteed.

The invention discloses a method for deleting a default appearance customized object and terminal equipment thereof, belonging to the fields of mobile communication. The method comprises the following steps: receiving a command for deleting an appearance customized object, which is transmitted by a server; and when the appearance customized object is a default appearance customized object, deleting the default appearance customized object and setting a new appearance customized object to be a default appearance customized object. The terminal equipment comprises a receiving module, a processing module and a setting module. The invention can ensure that the terminal equipment can supply appearance display when the original default appearance customized object is deleted by setting the other appearance customized object to be the new default appearance customized object when one default appearance customized object is deleted, thereby ensuring the experience quality of a user.
