Abstract
Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In some embodiments, the information transmitted to the network distinguishes between voice communications and other communications (e.g., other IMS communications) and is transmitted prior to establishment of a dedicated bearer for IP multimedia subsystem (IMS) signaling for the apparatus.
Claims20
A method, comprising:
- receiving, by a base station prior to establishment of a dedicated bearer for IP multimedia subsystem (IMS) signaling for a user equipment (UE) device, first information from the UE device in a radio resource control (RRC) connection request message, wherein the first information includes an indication specifying that the UE is requesting a mobile originating voice over long term evolution (VoLTE) call, wherein the indication differentiates between mobile originating VoLTE IMS communications and other IMS communications;
- and
- communicating, by the base station with the UE device for the VoLTE call, via a dedicated bearer for IMS signaling that is configured based on the first information.
An apparatus, comprising:
- one or more memories;
- and
- one or more processors configured to execute instructions stored on the one or more memories to:
- transmit, to a base station prior to establishment of a dedicated bearer for IP multimedia subsystem (IMS) signaling for the apparatus, first information in a radio resource control (RRC) connection request message, wherein the first information includes an indication specifying that the apparatus is requesting a mobile originating voice over long term evolution (VoLTE) call, wherein the indication differentiates between mobile originating VoLTE IMS communications and other IMS communications;
- and
- communicate with the base station for the VoLTE call, via a dedicated bearer for IMS signaling that is configured for the apparatus based on the first information.
A non-transitory computer-readable medium having instructions stored thereon that are executable by a UE device to perform operations comprising:
- transmitting, to a base station prior to establishment of a dedicated bearer for IP multimedia subsystem (IMS) signaling for the UE device, first information in a radio resource control (RRC) connection request message, wherein the first information includes an indication specifying that the UE device is requesting a mobile originating voice over long term evolution (VoLTE) call, wherein the indication differentiates between mobile originating VoLTE IMS communications and other IMS communications;
- and
- communicating with the base station for the VoLTE call, via a dedicated bearer for IMS signaling that is configured for the UE device based on the first information.
