Abstract:
The present invention discloses a service data scrambling method, a service data descrambling method, an apparatus, and a system, and relates to the communications field. The service data scrambling method includes: receiving service data; using a service characteristic corresponding to the service data as a part of a scrambling parameter; generating a scrambling sequence according to the scrambling parameter; scrambling the service data according to the scrambling sequence; and sending the service data. According to the present invention, it is resolved that relatively great interference is generated when multiple pieces of different service data are simultaneously transmitted in a same service area, and achieving an effect that interference between different service data sent simultaneously in the same service area can be reduced to a great extent.
Abstract:
The method includes: processing a PSNR of each segment of each sample video, determining an ePSNR predictive model according to preset parameters obtained after processing and mean opinion scores of all sample videos, and determining an enhanced mean opinion score eMOS predictive model according to the predictive model. Then, for any video that needs to be evaluated, QoE of the video that needs to be evaluated may be determined according to only the enhanced MOS predictive model and an ePSNR determined according to the ePSNR predictive model. In comparison with a prior-art method for determining QoE in which only a mean value of PERNs of all frames is considered, in this process of measuring quality of experience of a mobile video service, as many as factors that affect a PSNR of a video are considered. Therefore, accurate measurement of quality of experience of an HAS video service can be implemented.

The method includes: configuring at least two on-duration time lengths of a discontinuous reception; performing the discontinuous reception according to a first on-duration time length in the at least two on-duration time lengths; switching the first on-duration time length of the discontinuous reception to a second on-duration time length according to the configured at least two on-duration time lengths when a set condition is satisfied; and performing the discontinuous reception according to the second on-duration time length.
Abstract:
The present invention discloses a data sending method and a user equipment, and relates to the field of mobile communications. The method includes: receiving at least two uplink grants allocated by a base station; grouping uplink grants received at different moments in the at least two uplink grants to obtain multiplexing resources; and multiplexing data to be sent onto transport blocks corresponding to the multiplexing resources and sending the transport blocks. The user equipment includes a receiving module, a processing module and a sending module. In embodiments of the present invention, uplink grants are grouped according to sending moments of transport blocks corresponding to the uplink grants so as to determine multiplexing resources, and data is multiplexed onto transport blocks corresponding to the grouped uplink grants and the transport blocks are sent.

Embodiments of the present invention provide a method for semi-persistent shared resource scheduling, and an apparatus. The method includes: sending, by a base station to M user equipments UEs, a configuration enabling message for semi-persistent shared resource scheduling, where M is an integer greater than or equal to two; and periodically scheduling, by the base station, transmission time-frequency resources for the M UEs according to the configuration enabling message for semi-persistent shared resource scheduling, to send data to the M UEs, where the transmission time-frequency resources that the base station schedules to the M UEs each time are a same transmission time-frequency resource.
Abstract:
Embodiments of the present invention disclose a method, device, and system for processing streaming media service data. When a user equipment detects a service terminate operation or a service switching operation performed by a user, the user equipment sends a scheduling terminate message to a scheduling device, so that the scheduling device can timely learn that the user equipment has stopped a streaming media service being performed, and immediately stop scheduling, according to the scheduling terminate message, streaming media service data requested by the user equipment to the user equipment.
Abstract:
The present invention discloses a network connection method and system. The method includes: grouping a plurality of terminals, allocating group identities, and establishing a mapping relationship between the group identities and terminal identities; establishing a group-based signaling radio bearer and a group-based data radio bearer for each group; allocating, when a terminal in each group access a network, the terminal the group-based signaling radio bearer and group-based data radio bearer corresponding to the group to which the terminal belongs according to a mapping relationship between a group identities and a terminal identity, so that the terminals initiate network access by using the group-based signaling radio bearer and the group-based data radio bearer. The signaling overhead of establishing signaling connection and data bearer may be reduced though the technical solution of the present invention.
Abstract:
Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping. In one embodiment, a base station adds a component carrier (CC) for a user equipment (UE). The base station determines a timing advance (TA) group to which the added CC belongs. The TA group is a set of CCs that can share a TA. The base station sends identification information that identifies the TA group to the UE.
