The invention discloses a method for monitoring the video quality of an internet protocol (IP) television, which comprises: step 1, a multicast source server establishes a multicast test channel and sends an IP multicast test stream, wherein the IP multicast test stream has an IP multicast test pack containing sequence number, the sequence numbers of the adjacent test packs being increased progressively; step 2, a digital subscriber line access multiplexer is added into the multicast test channel to receive the IP multicast test stream, and inspects the video quality of IP television according to the continuity of sequence number of the IP multicast test pack, and sends the test result to a service management system; step 3, the service management system receipts and then processes the test result and displays the video quality of IP television. Therefore, the video quality of IP television can be monitored regardless of user data stream.

The invention provides a wireless network built-in POI self-service GPS real-time position reporting method and device. The invention has the following beneficial effects: integrating all the hardware of the backstage communication server, GIS server and database server and the software needing to be used in a system; being capable of completing the functions of the traditional server backstage by the single machine and directly converting the longitude and latitude position information which can not be understood by people into the position information which can be understood by people; using the GSM wireless network and SMS for communications, without GPRS traffic cost of the traditional machines or occupation of GSM network bandwidth; being used in the single machine: any user can carry out SMS control and receive information with the mobile phone, without carrying the computer for online query; and being used in the single machine: others can not know the telephone number and password of the user, thus ensuring strong confidentiality for the user of the product and avoiding the privacy from being divulged.

A mobile communications system includes a plurality of cell segments each allocated primary carriers to carry circuit-switched traffic and packet data carriers for carrying packet-switched traffic. The packet data carriers include two sets of carriers, a main set of carriers (F1, F2, or F3) and a secondary set of carriers (F4, F5, and F6). The main packet data carriers (F1, F2, and F3) are allocated to corresponding cell segments. The secondary carriers (F4, F5, and F6) are allocated to high capacity segments, which may be segments having high bursty traffic or segments in which a hierarchical cell structure is implemented. For high bursty cell segments, the main carriers (F1, F2, and F3) are used to carry control signaling for performing selection or reselection. However, in such high bursty cell segments, the secondary carriers (F4, F5, and F6) are not used for performing cell segment selection or reselection.

The invention relates to a wired network monitor system, which comprises M independent information collectors, a data center and M independent monitored network units, wherein the output terminal of each independent information collector is connected with the input terminal of the data center; the input terminals of the M independent information collectors are connected with the output terminals of the M independent monitored network units; each independent monitored network unit is connected with N independent users; and the N independent users corresponding to each monitored network units are different from the N independent users corresponding to other monitor network units. The wired network monitor system has the advantages that the data collection and analysis is achieved by the information collectors at the outlet of each network unit by adopting a multi-step data processing and centralized control manner; and the information collection policy and the data summarization are achieved by the data center, so that the processing of massive data is distributed to different units to achieve maximally centralized control, thereby reducing the data quantity to be stored. The wired network monitor system can work normally only using a simple network connection, and has the advantages of convenient implementation and simple maintenance.

The invention provides a channel subscription method of digital pay-television to satisfy the individuation requirement of different users and a system to realize the method, belonging to television communication technology. The method comprises the following procedure: network server packs the channel, which selected on the browser by the terminal user, as a individual package and sends to conditional access system; the conditional access system creates the subscription channel record according to the individual package and sends the authorized management information to user terminal adaptervia IP network. In the digital pay-television channel subscription system, user terminal adapter is connected with dual-way gateway; the browser is connected with dual-way gateway by network service;the conditional access system is connected with dual-way gateway, and user management system is connected with the conditional access system. The invention has the advantage that user can select the demand television program through network browser; user can also realize real-time video-on-demand and instant authorization and other services via network.

The invention discloses a detecting method of an auxiliary CPU operating condition, and a detection system, and also discloses a multi-CPU device and a detection component of the auxiliary CPU operating condition. The detecting method is suitable for an device with a main CPU and at least one auxiliary CPU, and the following steps are executed after the main CPU and each auxiliary CPU is started;based on the hardware interrupt, the auxiliary CPUs periodically perform data writing operation to the second hardware logical cells arranged with the auxiliary CPUs in a one-to-one correspondence manner; when a first hardware logical cell cannot detect that the data of a second hardware logical cell is written after the preset time, the disorder of the corresponding auxiliary CPUs is identified and reported to the main CPU. By the method, the rapid detection of the main CPU to the working conditions of the auxiliary CPUs can be realized, and the high real-time property of the message processing can be further guaranteed; and in addition, the communication band width between the boards is not occupied.
