By using the present invention, the client can request the server for a data file with a bit rate or resolution level matching the network resource, thereby increasing resource utilization of the server. | 04-03-2014 |
| 20140269584 | METHOD AND DEVICE FOR IMPROVING CELL THROUGHPUT BASED ON STREAMING MEDIA SERVICE - Embodiments of the present invention provide a method and a system for improving a cell throughput based on a streaming media service. The method includes: pre-adjusting, according to a channel quality sampling value of two clients in the same cell that are performing a streaming media service, an air interface resource allocated to the two clients; acquiring a variation of a cell throughput that exists after the air interface resources of the two clients are pre-adjusted; and if the variation of the cell throughput that exists after the air interface resources of the two clients are pre-adjusted is greater than a preset resource adjustment threshold, allocating the pre-adjusted air interface resources to the two clients, so that the two clients two capable of receiving streaming media content having an adjusted code rate value from a media server. | 09-18-2014 |
| 20150095413 | METHOD FOR PROVIDING SERVICE INFORMATION, APPARATUS, AND NETWORK SYSTEM - Embodiments of the present invention provide a method for providing service information, an apparatus, and a network system. The method for providing service information in the embodiments of the present invention includes: receiving, by a radio access network cache, a service request message from a mobile terminal, where the service request message includes a service identifier and moving state information of the mobile terminal; and if the radio access network cache determines that the radio access network cache stores service information corresponding to the service identifier and the moving state information satisfies a preset activation condition, returning, by the radio access network cache, acknowledgment information to the mobile terminal, and sending the service information to the mobile terminal. | 04-02-2015 |
| 20150138982 | Policy Control Method, and Device - Embodiments of the present invention provide a policy control method and a device. The method includes: receiving a quality of experience QoE report sent by a user equipment UE, where the QoE report includes a QoE metric and a cell identity of a serving cell of the UE; and performing cell policy control according to the QoE report. In the embodiments of the present invention, a QoE server receives a QoE report sent by a UE, where the QoE report not only includes a QoE metric, but also includes a cell identity of a serving cell of the UE. Therefore, the QoE server performs policy control within a cell range according to the QoE report, thereby effectively improving flexibility of QoE service deployment and enhancing user experience. | 05-21-2015 |
| 20150189040 | Service Data Cache Processing Method and System and Device - Embodiments of the present invention provide a service data cache processing method and system and a device. The method includes receiving statistical information of service data and sending a service data push request to a service provider SP device according to the statistical information, so that the SP device sends service data to a primary cache deployed in a core network or an edge cache deployed in an access network. | 07-02-2015 |
| 20160080977 | DATA TRANSMISSION CONTROL METHOD AND APPARATUS BASED ON WIRELESS COMMUNICATIONS NETWORK - According to a method and apparatus for controlling data transmission in a wireless communications network, a service quality request message is sent to a PCRF when a data request message of a terminal is received; and the PCRF queries a current network status, so as to determine a processing instruction for a data request message of the terminal according to the current network status and the data request message, and process the data request message of the terminal according to the processing instruction. Therefore, processing on the data request message of the terminal not only depends on a parameter carried in the data request message of the terminal, but also uses the current network status as a constraint condition, so that a processing manner for the data request message can be adaptive to a real-time change of the wireless communications network. | 03-17-2016 |
