  • Patent number: 10257813
    Abstract: Various aspects of the present disclosure enable a plurality of mobile devices (UEs) within a cell to spread out in time their respective transmissions of signaling messages, such as cell update messages, when the network enables or disables enhanced uplink (EUL, sometimes referred to as high-speed uplink packet access or HSUPA) while the UE is in the CELL_FACH state, by changing SIB5 or SIB5bis. In this way, the network load may be reduced, and a network blockage that otherwise might result from large numbers of UEs simultaneously transmitting the cell update message can be avoided. According to one example, a network node may be configured to distribute CELL_UPDATE messages or procedures to UEs when the network node enables or disables EUL in CELL_FACH by changing SIB5 or SIB5bis over time to reduce the network load. According to another example, a UE may be configured for utilizing a random timer or back-off timer to defer cell updates.

  • Patent number: 10075778
    Abstract: An integrated base station provides uplink and downlink wireless connectivity between user equipment and a wireless communication network. In order to accommodate certain features of the network, a bypass switch of the integrated base station is employed so that the baseband module of the base station is bypassed as to those features. In this case, selected data obtained from the RF transceiver of the integrated base station is processed by equipment in the back end system instead of by the baseband module. A first operation mode enables the baseband module to process the selected data, while a second operation mode bypasses the baseband module so that the back end system performs the processing. The bypass switch may be permanently activated. The bypass process allows for processing of the selected data in an efficient manner without requiring replacement of the integrated base station, thereby providing an efficient and cost-effective solution.
