Abstract
A user equipment (UE) can determine when to send an initial request for a voice communication to an Internet Protocol (IP) Multimedia Subsystem (IMS) core of a telecommunication network. For instance, the UE can identify when a call setup instruction should be sent to the IMS to cause a communication channel to be established. The UE can determine whether the UE will experience a change to another radio frequency band or radio technology based on test data, and delay sending the call setup instruction for a time period during which the test data can be analyzed.
Claims20
A method comprising:
- receiving, by a user equipment (UE), a request to establish a Voice over New Radio (VoNR) communication over a fifth generation telecommunications network;
- identifying, by the UE, that the request is associated with a call setup instruction for sending to a first Internet Protocol (IP) Multimedia Subsystem (IMS) associated with the fifth generation telecommunications network;
- pausing sending of the call setup instruction to the first IMS based at least in part on identifying the call setup instruction;
- receiving one or more test results from a memory of the UE, the one or more test results indicating a signal strength or a signal quality of at least one of:
- a first radio frequency band of the fifth generation telecommunications network, a second radio frequency band of the fifth generation telecommunications network, or a third radio frequency band of a fourth generation telecommunications network;
- and
- sending, by the UE and based at least in part on the one or more test results, the call setup instruction to one of:
- the first IMS associated with the fifth generation telecommunications network or a second IMS associated with the fourth generation telecommunications network.
5 more elements
A system comprising:
- one or more processors;
- and
- memory storing computer-executable instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
- receiving, by a user equipment (UE), a request to establish a voice communication over a first telecommunications network;
- identifying, by the UE, that the request is associated with a call setup instruction for sending to a first Internet Protocol (IP) Multimedia Subsystem (IMS) associated with the first telecommunications network;
- pausing sending the call setup instruction to the first IMS based at least in part on identifying the call setup instruction;
- and
- sending, by the UE and based at least in part on one or more test results, the call setup instruction to the first IMS associated with the first telecommunications network or a second IMS associated with a second telecommunications network different from the first telecommunications network.
5 more elements
A method comprising:
- receiving, by a user equipment (UE), a request to establish a voice communication over a first telecommunications network;
- determining a time period to delay sending the request to establish the voice communication;
- accessing, during the time period, a test result indicating a signal strength or a signal quality for the UE to send the request using a first radio frequency band and a second radio frequency band;
- and
- sending, by the UE and based at least in part on the test result, an instruction to a first Internet Protocol (IP) Multimedia Subsystem (IMS) associated with the first telecommunications network or a second IMS associated with a second telecommunications network different from the first telecommunications network.
