20120100856 | MOBILE COMMUNICATION SYSTEM, TERMINAL DEVICE, AND BASE STATION - In a mobile communication system, a handover of a terminal device (MT) from a macrocell base station (eNB) to a small cell base station (HeNB) is controlled via a host device (MME or HeNB-GW). Physical cell ID deployment map information (PCI deployment map information), which includes at least information (PCI/CGI map information) indicating the correspondences between physical cell IDs and unique cell IDs of CSG cells for which access is granted, is generated in the host device (MME or HeNB-GW). When the terminal device measures the reception quality for surrounding CSG cells for handover control to any of the CSG cells, the terminal device uses the PCI deployment map information to generate a measurement result report. Thus, a service interruption caused by handover control to an inaccessible small cell can be avoided, and the wait time for handover control can be reduced. | 04-26-2012 |

The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications. | 10-18-2012 |

20140036873 | COMMUNICATION SYSTEM, MOBILE TERMINAL, ROUTER, AND MOBILITY MANAGEMENT ENTITY - With the deployment of the Mobile Routers, some of the mobile devices would access the IP services, e.g. Remote Local IP Access (LIPA), via the local connections provided by the Mobile Router. In such cases, the mobile devices may be detached from the 3GPP access, and thus lose the capability of receiving certain services, e.g. CS domain related services. This invention presented a solution to allow the mobile device to continue enjoying the services provided via 3GPP access by placing the mobile device into a special state and binding Mobile Router's context with the mobile device's context. In this way, the mobile operator's core network would be able to trigger the mobile device to receive the CS service even its 3GPP access connections are removed. | 02-06-2014 |
