  • Patent number: 11489881
    Abstract: Examples described herein involve an internet protocol (IP) multimedia subsystem (IMS) network. An example process may include receiving, from a user equipment (UE), a request for an IMS session. The IMS session may be between the IMS network and the UE. The process may include requesting a subscriber management component to provide platform information associated with the IMS session. The platform information may identify a platform device that hosts a user plane function (UPF) for the IMS session. The process may include receiving, from the subscriber management component, the platform information and selecting, based on the platform information, a user plane component of the IMS network. The user plane component may perform a user plane operation associated with the IMS session. The process may include causing the user plane component to perform the user plane operation for the IMS session.

  • Patent number: 9497329
    Abstract: An approach is described for providing shared trunking between a telephony gateway and an end office switch. The telephony gateway processes a packetized voice call, and interfaces a shared trunk to an end office switch (e.g., Class 5 switch) configured to switch calls over a circuit-switched telephone network. The trunk utilizes out-of-band signaling (e.g., Primary Rate Interface (PRI) signaling) in support of call establishment or teardown of the packetized voice call.

  • Patent number: 9007896
    Abstract: A method may include receiving a number of calls and identifying destinations associated with the calls, where a first portion of the calls are associated with a first destination. The method may also include determining whether failure responses associated with calls forwarded toward the first destination indicate a problem or a possible problem associated with forwarding calls toward the first destination. The method may further include blocking, when the failure responses indicate a problem or a possible problem, at least some of the first portion of calls from being forwarded toward the first destination.
