A communication method and a communication device are provided. The method includes: establishing a scenario and determining a task of the scenario, where a plurality of communication systems exist in the scenario, and the task is completed via at least one communication service; selecting at least one communication system for the task from the plurality of communication systems; and controlling the at least one communication system to transmit the communication service required by the task.

Communication method and device

A measurement method and device for wireless network communication system is disclosed. The method enables operators to use recording information to detect whether there is any problem in network and to perform some necessary optimizing work by enabling user equipment (UE) to automatically record some measurement logs and to periodically report them to the network. Because the information is automatically collected by the UE, the method effectively reduces the workload and cost devotion which is needed for network measurement by manual road measurement. The method enables the operators to obtain measurement information of geography areas that can not be obtained in ordinary road measurement because the UE is randomly distributed at any position in the network.

Measurement method and device for wireless network communication system

The present invention discloses a method and access network device for interference coordination, said method comprises: getting time-frequency resource of cell, and dividing said time-frequency resource into multiple resource subsets; grouping users to be scheduled in the cell into multiple user groups according to AOA, the amount of said user groups is equal to the amount of said resource subsets, different user groups have different resource subset selection priority orders; allocating time-frequency resource of the resource subsets to users, which are in neighboring cells and have the same direction, according to said resource subset selection priority orders of the user groups. The present invention could reduce inter-cell co-frequency interference and improve channel quality.

Method and access network device for interference coordination

The present invention discloses a method and equipment for saving energy. The method comprises the following steps: the first network node acquires load information of the second network node next to the first and modifies energy saving state according to its own load information and that of said second network node; said first and second network nodes send information on indication for saving energy state to the adjacent third network node and inform the information of modifying energy saving state to said third network node based on said information on indication for saving energy state. Embodiments of the present invention optimize resource utilization rate of the whole network.

Method and equipment for saving energy

Methods, apparatuses, and systems for establishing a radio bearer include a User Equipment (UE) that divides IP data flow of a service into multiple service data flows having different QoS requirements according to media parameter information, determines QoS parameters of each service data flow, and sends each service data flow and the corresponding QoS parameters to an Access Point (AP). The AP allocates wireless resources for each service data flow according to a local QoS strategy, builds the corresponding wireless bearing, and binds the service data flow and the wireless bearing. The UE also builds the corresponding wireless bearing for each service data flow and binds the service data flow and the wireless bearing. During uplink and downlink data transmission, the AP and UE can map each service data flow to the corresponding wireless bearing for transmission according to the QoS requirements of different service data flows.

A method and a system for coordinated transmission, and a mobile terminal and network side device are provided. The method for coordinated transmission includes: reporting by the terminal of a signal measurement result; determining the coordinated transmission state of the terminal according to the signal measurement result; and providing transmission service for the terminal according to the determined transmission state.

Method and system for coordinated transmission and a mobile terminal and network side device

Disclosed are a scheduling method, device and system based on quality of service. The method includes: for downlink service data, an access point (AP) or a gateway (GW) determines the quality of service (QoS) level of a downlink service packet of a media access control (MAC) layer according to the QoS attribute information of the downlink service packet of the IP layer, and then the AP transmits and schedules radio resources according to the QoS level; for uplink service data, user equipment (UE) determines the QoS level of an uplink service packet of the MAC layer according to the QoS attribute information of the uplink service packet of the IP layer, and reports the QoS level and the other QoS parameters to the AP in the manner of a scheduling request, and the AP completes the transmitting and scheduling of radio resources according to the QoS level, so that the UE transmits the uplink service data to the AP. Aimed at low-cost hot spot and indoor data service access, the present invention provides a novel network architecture and a perfect QoS service mechanism.

Scheduling method, device and system based on quality of service

Disclosed are a minimization of drive test (MDT) method, system, and device, relating to the technical field of radio communications for solving the problem that the MDT measurement data fails to be reported because the data volume of MDT measurement data reported by a user equipment (UE) exceeds the volume of data capable of being stored by a PDCP module. In the present invention, a UE receives a notification, sent from a base station, of reporting an MDT measurement result; and when a total data volume of the stored MDT measurement result data to be reported is greater than the volume of data capable of being stored by a PDCP module, the UE reports the MDT measurement result data to the base station in one or more times, the total data volume of MDT measurement result data reported each time being not greater than the volume of data capable of being stored by the PDCP module. With the present invention, the problem that the MDT measurement data fails to be reported because the data volume of MDT measurement data reported by the UE exceeds the volume of data capable of being stored by the PDCP module can be solved.
