  • Patent number: 10231152
    Abstract: The present invention discloses a network handover method, where after UE in an LTE network requests circuit switched fallback CSFB, an MME instructs an eNB to move the UE from the LTE network to a 2G or 3G network, and requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network for the CSFB, so that the 2G or 3G network allocates a CS domain resource to the UE. After handing over to the CS domain, the UE may perform a CS domain call. By using embodiments of the present invention, an access delay is reduced when the UE accesses the CS domain of the 2G or 3G network, duration of an entire voice call is shortened, and user experience is improved.

  • Publication number: 20190064770
    Abstract: Exemplary embodiments for multiple standard cell libraries are disclosed that include one or more standard cells and one or more corresponding standard cell variations. The one or more standard cell variations have similar functionality as their one or more standard cells but are different from their one or more standard cells in terms of geometric shapes, locations of the geometric shapes, and/or interconnections between the geometric shapes. The exemplary systems and methods described herein selectively choose from among the one or more standard cells and/or the one or more standard cell variations to form an electronic architectural design for analog circuitry and/or digital circuitry of an electronic device. In an exemplary embodiment, a semiconductor foundry and/or semiconductor technology node can impose one or more electronic design constraints on the placement of the one or more standard cells onto an electronic device design real estate.

  • Patent number: 10212634
    Abstract: A communication method includes: sending, by an MME, a bearer setup request message to an eNodeB, where the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and when the MME receives a bearer setup failure message sent by the eNodeB in response to the bearer setup request message, sending, by the MME, an indication message to the user equipment, where the indication message is used to indicate that a voice over VoIMS of the user equipment is unavailable. When setup of a voice bearer of a VoLTE call fails, the user equipment is notified that a VoLTE is unavailable, so that the user equipment can be prevented from continuing attempting to initiate the VoLTE call and exacerbating cell congestion.
