Abstract: A device may receive a signal strength indicator associated with a connection between a mobile device and a first base station. The signal strength indicator may indicate a strength of a radio signal received by the mobile device from the first base station. The device may transmit the signal strength indicator to a network device, and may receive, from the network device, a first notification to activate a second base station based on the signal strength indicator. The device may activate the second base station based on the first notification. The second base station may provide temporary wireless connectivity for the mobile device.

Abstract: A femto cell at a customer premises, such as an IP-based femto Base Transceiver System (IP-BTS), can be configured as a “private access” node intended to service a limited set of mobile stations. However, mobile stations not associated with the private femto cell may acquire and lock onto the femto BTS. To avoid service blockages in such cases, the private femto BTS will allow call access attempts by, and call deliveries to, a non-associated mobile station, despite the “private access” configuration. However, upon completion of call set-up, the non-associated mobile station is directed to initiate handoff, from the private femto cell coverage provided by the femto BTS into a cell coverage of a base station of the macro network, to conserve femto cell resources for use in servicing calls of the associated mobile station(s).

Abstract translation: 诸如基于IP的毫微微基站收发器系统（IP-BTS）之类的客户驻地的毫微微小区可被配置为旨在服务有限的一组移动站的“专用接入”节点。 然而，与私有毫微微小区无关的移动站可以获取并锁定到毫微微BTS。 为了避免在这种情况下的服务阻塞，私人毫微微BTS将允许呼叫接入尝试，并且呼叫非接入移动台的传送，尽管有“私有接入”配置。 然而，在完成呼叫建立之后，非关联移动台被指示从毫微微BTS提供的私人毫微微小区覆盖范围开始到宏网络的基站的小区覆盖范围内的切换，以节省毫微微小区 用于维护相关移动台的呼叫的资源。

Abstract: Femto cells that extend mobile network coverage into customer premises operate in a frequency band typically assigned to a macro network. As disclosed, to facilitate system discovery and registrations of mobile stations with femto cells, a carrier designates one the channels within the band as a primary channel for its femto cells. For example, neighbor list messages transmitted by macro network base stations can provide frequency and PN code information directing mobile stations to search the primary channel for a PN code of the femto cells. Also, a mobile station PRL may identify femto cells by SID/NID. The SID is that of the carrier's macro network, whereas the NID may be a NID of the macro network or one specifically assigned to femto cell operations. The PRL uses frequency acquisition information for the femto cells that is the same as or similar to that for one of the macro networks.

Abstract: In a programmable logic device having a plurality of external pins each of which may be driven by an output drive structure controlled by a programmable logic block, a logic device such as an OR gate or a programmable pull-up or pull-down switch is inserted between the input terminal of the output drive structure and the programmable logic block or other internal logic block which controls the output driver. This inserted structure allows the macrocell to be used for internal logic while the output drive structure is used to stabilize power or ground voltage.

Abstract: A carry-lookahead structure for programmable architectures includes a number of M-bit carry lookahead units, each M-bit unit having two parallel programmable carry paths having AND gates controlled by configuration bits to program the beginning and end of an operating carry chain within the M-bit units, as well as the beginning locations in each unit, one path generating a first set of carry bits for the case of the carry-in equal to 0, and the other generating a second set of carry bits for the case of the carry-in equal to 1, and at least one multiplexer controlled by the carry-in for selecting one of the two carries at the most significant bit of the first and second sets of carry bits as carry-out of the unit. Each M-bit unit may further include multiplexers controlled by the carry-in for selecting which of the first and second sets of carry bits are the correct carry bits for addition and M sum logic elements for generating the outputs of sum bits. An alternative is an adder in which the precomputation of the sums is performed for the two possible values of carry-in in each M-bit unit, providing two sets of sum bits, and where multiplexers select which of the two sets of the sum bits is the correct sum and which of the two carry bits produced in the most significant bit of the unit is used as the carry-out of the unit in response to the actual carry-in value of the unit.
