  • Patent number: 11638254
    Abstract: A multi-subscriber identification module (multi-SIM) device includes plural SIMs, plural radio frequency (RF) resources, and a baseband processor. The plural RF resources are assigned to the plural SIMs, a first portion of the RF resources supporting use of a non-limited channel configuration and a second portion of the RF resources supporting use of a limited channel configuration according to a radio resource control (RRC) protocol. The baseband processor, in response to RF resource use request intervals of two or more target SIMs among the plural SIMs overlapping each other, control the RF resources to support the use of the non-limited channel configuration for one of the two or more target SIMs and to support the use of the limited channel configuration for the other of the two or more target SIMs, based on information regarding networks respectively corresponding to the two or more target SIMs.

  • Patent number: 8842685
    Abstract: A method includes transferring a general query message to managers of a mobility control server in response to receiving, from a router, the general query message for detecting a mobile node that requested to receive multicast data; storing, in a multicast mapping table, an address of the mobile node that requested to receive the multicast data when a membership report message of the mobile node is received from at least one of the managers and transferring the membership report message to the router; and forming a tunnel between the router and a manager that transfers the membership report message.
