20150134769 | DATA SHUNTING METHOD, DATA TRANSMISSION DEVICE, AND SHUNTING NODE DEVICE - Embodiments of the present invention relate to a data shunting method, a data transmission device and a shunting node device, the data shunting method provided in the embodiments of the present invention includes: acquiring the number of to-be-transmitted shunted data packets which are cached in the shunting node device; when the number of the to-be-transmitted shunted data packets is less than a first threshold value, transmitting shunted data to the shunting node device, otherwise, not transmitting the shunted data to the shunting node device. The data shunting method provided in the embodiments of the present invention enables the data transmission device to provide the shunting node device with an appropriate shunted data rate. | 05-14-2015 |
20150156719 | METHOD AND RELATED EQUIPMENT FOR SENDING SIGNALING - The present invention relates to the field of communications, and in particular, to a method and related equipment for sending signaling. The method includes: when a power consumption preference of a user equipment is changed to lower power consumption, determining whether a first timer used for restricting sending of a lower power consumption preference indication expires, and if a determination result is yes, sending a lower power consumption preference indication to a base station; and when the power consumption preference of the user equipment is changed to higher power consumption, sending a higher power consumption preference indication to the base station, or determining whether a second timer used for restricting sending of a higher power consumption preference indication expires, and if a determination result is yes, sending a higher power consumption preference indication to the base station. The present invention may improve user experience. | 06-04-2015 |
20150156733 | Method and Apparatus for Power Control - A power control method includes obtaining power headroom information of an aggregated carrier of a User Equipment (UE). The aggregated carrier includes at least one component carrier group and at least one first carrier, or includes at least one component carrier group, or includes at least two first carriers. The component carrier group includes at least two second carriers, and the first carrier and the second carrier are single carriers, The method also includes adjusting transmit power of the aggregated carrier according to the power headroom information. | 06-04-2015 |
20150156750 | ACCESSING METHOD, EQUIPMENT AND BASE STATION - Embodiments of the present invention provide an access method, a user equipment and a base station. In the present invention, a user equipment obtains a first synchronous channel resource; uses the first synchronous channel resource to send an access request to a base station, for requesting to access the base station; receives access feedback sent by the base station, and determining whether access is successful according to the access feedback. In this way, occupation of the user equipment on an access resource during access may be reduced, and utilization efficiency of the access resource is improved. | 06-04-2015 |
20150156798 | Method, Device, and System for Determining Timing Advance Grouping - 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. | 06-04-2015 |
