|20150257170||METHOD AND APPARATUS FOR GROUP MANAGEMENT DURING MACHINE-TO-MACHINE COMMUNICATION - The present invention provides a method and an apparatus for group management during M2M communication. The method for group management during M2M communication includes receiving a group creation request sent by a requesting apparatus and carrying a group type of a group requested to be created, checking consistency between member types of members in the group and the group type and setting a consistency check flag of the group according to a consistency check result, and returning a group creation response that carries the consistency check result to the requesting apparatus.||09-10-2015|
|20150257068||COMMUNICATION METHOD, USER EQUIPMENT, AND SINGLE RADIO CONTROLLER - Embodiments of the present invention provide a communication method, a user equipment, and a single radio controller. The method includes: establishing, by a user equipment, a first connection with an SRC by using a first communications network; and sending, by the user equipment, NAS signaling or Layer 3 signaling of a second communications network to the SRC by using the first connection, and/or receiving NAS signaling or Layer 3 signaling of a second communications network from the SRC by using the first connection. Therefore, in the embodiments of the present invention, NAS/L3 signaling of a second communications network is transmitted over the first connection that is established in a first communications network, so that a service can flexibly switch between different RATs, and the system efficiency is improved.||09-10-2015|
|20150257053||METHOD AND DEVICE FOR HANDOVER OF MOBILE TERMINAL BETWEEN BASE STATIONS - The present invention discloses a method and a device for handover of a mobile terminal between base stations, which relates to the field of communications technologies and can realize handover of user equipment between base stations in a condition of ensuring that business services of a neighbouring base station and a target base station are not interrupted. An embodiment of the present invention includes: a source base station obtains a designated channel resource, and, by negotiating with a target base station and a neighbouring base station, determines to send a handover command to user equipment.

|20150256243||METHOD AND APPARATUS FOR ACQUIRING A PRECODING MATRIX INDICATOR AND A PRECODING MATRIX - In the field of communication technologies, a method and an apparatus for acquiring a Precoding Matrix Indicator (PMI) and a Precoding Matrix (PM) are provided. The method includes: acquiring a reference PMI and a differential PMI according to a first non-differential codebook and a first diagonal differential codebook, where codewords included in the first diagonal differential codebook form a diagonal matrix. The apparatus includes a PMI acquiring module. Acquiring a reference PMI and a differential PMI according to a non-differential codebook and a diagonal differential codebook can reduce the feedback overhead or improve the feedback precision; and the fact that a codeword included in the diagonal differential codebook is a diagonal matrix can maintain amplitude characteristics (for example, a constant modulus characteristic, and a finite character set constraint characteristic) of elements of the non-differential codebook or facilitate power distribution among antennas.||09-10-2015|
