20090285182 | METHOD, COMMUNICATION SYSTEM, AND NETWORK ENTITY FOR GROUP NODES HANDOVER - A method, a communication system, and a network entity for group handover are provided. The method includes the following steps. A first tunnel connection is established between a mobile relay station (MRS) and a serving entity (SE). A target entity (TE) obtains group information about the group to be handed over, and the group information includes information about a first tunnel. According to the group information, the TE configures information about a second tunnel for the group, and the information about the second tunnel is required for group handover. The group nodes are handed over from the SE to the TE according to the information about the second tunnel. Thereby, the group information that needs to be transmitted in a handover process is reduced, and problems resulting from the number of handovers can be avoided. | 11-19-2009 |
20100062772 | METHOD, WIRELESS COMMUNICATION SYSTEM, AND GROUP MOBILITY CONTROLLER FOR PROCESSING GROUP MOBILITY - A method, a wireless communication system, and a group mobility controller (GMC) for processing group mobility are provided by the exemplary embodiments of the present invention. In the method, a fixed GMC paging group identifier (PG-ID) is assigned to the GMC when the GMC starts up a group mobility function; and a target network obtains group information of the GMC, and updates a PG-ID list of the target network with the group information of the GMC during a message interaction process when the GMC hands over from a serving network to the target network, and then utilizes the updated PG-ID list during a subsequent interaction process with a group node. The system includes a GMC, a serving network, and a target network. The signaling storm raised when numbers of terminals in an idle mode perform location update at the same time during the group mobility can be avoided according to the above technical solutions, thereby realizing the economy of air interface resources and signaling overheads. | 03-11-2010 |
20130115920 | Method and Apparatus for Mobile Internet Protocol Registrating or Deregistrating - A computer program product can be used to store instructions operable in a physical entity in which a destination MIP Foreign Agent (FA) resides. The program product includes code for: obtaining an identity of a mobile terminal (MT ID) and address information of an anchor proxy mobile node or an authenticator; sending a message carrying the MT ID to the anchor proxy mobile node or the authenticator; receiving a credential corresponding to the MT ID sent from the anchor proxy mobile node or the authenticator after the anchor proxy mobile node or the authenticator receives the message carrying the MT ID and searches for the credential corresponding to the MT ID; and implementing MIP registration or deregistration for the mobile terminal using the credential. | 05-09-2013 |
20130151723 | STREAM MEDIA CHANNEL SWITCH METHOD, SWITCH AGENT, CLIENT AND TERMINAL - The channel switch method includes: playing stream media data of a current channel by a playing module of a stream media client; after a channel switch agent receives a channel switch request message sent from a service module of the stream media client, sending the channel switch request message to a stream media server by the channel switch agent, wherein the channel switch request message carries with switched channel ID information and client ID information of the stream media client; sending stream media data corresponding to the switched channel ID to the playing module of the stream media client by the stream media server through a stream playing session corresponding to the client ID, and playing the stream media data corresponding to the switched channel ID by the playing module. | 06-13-2013 |
20140079007 | DATA STREAM TRANSMISSION METHOD AND RELATED DEVICE AND SYSTEM - Embodiments of the present disclosure relate to the field of communications technologies, and disclose a data stream transmission method, and a related device and system. The data stream transmission method includes: a user equipment establishes a first network link over a first network and a second network link over a second network with a network side, where the first network is different from the second network; the user equipment associates the first network link with the second network link; and the user equipment distributes, according a scheduling algorithm, a data stream to the first network link and to the second network link for transmission. In the embodiments of the present disclosure, hybrid transmission of a data stream may be implemented in different networks. Compared with an existing solution, in the embodiments of the present disclosure, distribution may be performed more flexibly, and a quality of service assurance may be improved. | 03-20-2014 |
20140105318 | VIRTUAL MULTIPLE-INPUT MULTIPLE-OUTPUT COMMUNICATION METHOD AND DEVICE - The present invention provides a virtual multiple-input multiple-output communication method and device. The method includes: determining a user set to which a user equipment in a sector belongs, where the user set includes a first user set and a second user set, a user equipment in the first user set is in a beam coverage area of a first antenna group in the sector but is not in a beam coverage area of a second antenna group of the sector, and a user equipment in the second user set is in the beam coverage area of the second antenna group but is not in the beam coverage area of the first antenna group ( | 04-17-2014 |
20140302891 | METHOD, DEVICE, AND SYSTEM FOR REGULATING POWER CONSUMPTION - A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user's normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed. This reduces the power consumption of the network device. | 10-09-2014 |
20140369311 | Method, Terminal And Base Station For Multi-User Interference Suppression - Embodiments of the present invention provide a multi-user interference suppression method, terminal and base station. The method includes performing layer mapping on and precoding service data of each of paired users to obtain precoded output data, mapping the precoded output data and a common pilot sequence to a port of an antenna array for sending to each user by using the antenna array. Correspondingly, the embodiments of the present invention further provide a data receiving method, base station and terminal. By using a common pilot sequence based on the paired users, the same pilot sequence is used for each user in the paired users of a cell or a collaborative area, which is different from the technical solution in the prior art where a user-specific pilot is used and pilots of different users are orthogonal. | 12-18-2014 |
