20120327853 | Transmission Method of Femtocell - A transmission method of a femtocell includes the following steps. The femtocell receives and temporarily stores multiple real-time transport protocol (RTP) packets from a UE in a buffer. When the RTP packets are temporarily stored for a time period, the femtocell samples the buffer at a sampling rate to generate multiple CS data packets. The CS data packets include a current CS data packet. When there exists no previous CS data packet received from the UE, the femtocell calculates a timestamp of the current CS data packet according to a current timestamp. When there exists the previous CS data packet, the femtocell calculates the timestamp of the current CS data packet according to the timestamp and a connection frame number (CFN) of the previous CS data packet and a CFN of the current CS data packet. | 12-27-2012 |
20120331520 | Method and System for the Transmission of Wireless Data Stream - The disclosure provides a method and a system for transmitting wireless data stream. After a user equipment (UE) sends a packet data protocol (PDP) context activation request signaling to a base station, the base station checks whether the user equipment is allowed to activate a local Internet protocol access (LIPA) function. If the base station decides that the user equipment is allowed to activate the LIPA function, the base station informs a core network which executes authentication accordingly. The base station disconnects from the core network. The base station assigns a private IP address to the user equipment for implementing the LIPA function, so that the user equipment having the private IP address is directly connected to an external network through the base station without going through the core network. | 12-27-2012 |
20130012157 | METHOD AND SYSTEM FOR WIRELESS DATA FLOW - After receiving a packet data protocol (PDP) activation request signaling from a user equipment (UE), a base station checks whether to activate a local Internet protocol access (LIPA) function for the UE. If yes, the base station informs a core network (CN) for authentication and signaling control. If the user plane data from the UE is allowed to be transmitted via the LIPA, the base station assigns a private IP address to the UE; and the UE access internet via the base station. The base station determines whether user plane data from the UE passes through the CN; and the CN measures Internet service time provided to the UE. If all user plane data transmitted from the UE are allowed to be transmitted via the LIPA, the base station periodically transmits a data packet to the CN to maintain signaling link. | 01-10-2013 |
20130012222 | METHOD FOR PROCESSING USER EQUIPMENT CONNECTION UNDER A MIXED MODE AND FEMTOCELL SYSTEM - A method for processing user equipment (UE) connection under a mixed mode and a femtocell system are provided. The method for processing UE connection is used in a femtocell for processing the connection of a UE. The method includes the following steps. A connection request is received from a low priority UE under a mixed mode. Whether the measurement results corresponding to the femtocell satisfy threshold settings is determined in response to the connection request, wherein the measurement results include a path loss corresponding to the femtocell. If the measurement results satisfy the threshold settings, then the low priority UE is allowed to be connected to the femtocell. In one embodiment, suitable resource allocation, such as the allocation of power and code resource, is provided after the low priority UE is connected to the femtocell under the mixed mode. | 01-10-2013 |
20130029667 | IDENTIFICATION METHOD AND SWITCHING METHOD OF FEMTOCELL AND FEMTOCELL SYSTEM - A switching method of a femtocell includes steps of: a) detecting an air message, and determining, according to signal strength, a base station corresponding to a broadcast message in the detected air message as a standby base station; b) determining whether the standby base station is the femtocell according to a specific identification sequence and a pilot channel output power value in the broadcast message of the standby base station; according to step (b), determining a first standby base station corresponding to a first broadcast message as a base station of a first type; according to step (b), determining a second standby base station corresponding to a second broadcast message as a base station of a second type; and with respect to the first standby base station and the second standby base station, prioritizing the femtocell to switch to the first standby base station for service handover. | 01-31-2013 |

20130121314 | DOWNLINK ORTHOGONAL VARIABLE SPREADING FACTOR CODE ASSIGNMENT METHOD AND BASE STATION SYSTEM USING THE SAME - A downlink orthogonal variable spreading factor (OVSF) code assignment method is provided. It is determined whether a spreading factor required by a service request is greater than a remaining capacity of assignable spreading factors of a code tree. If not, the code tree is searched from a root until a node of a layer corresponding to the required spreading factor is reached and thus defined as a first node. During the searching, when a searched node is unassigned, the searching continues leftward in a lower layer; and when the searched node is in an assigned state, the searching continues rightward in a same layer of the searched node. It is determined, from the first node, whether any assignable code is available in the layer corresponding to the required spreading factor. If available, an assignable code is assigned to a communication service corresponding to the service request. | 05-16-2013 |
