Ericsson enables voice calls for wearables

Ericsson releases new Voice over LTE (VoLTE)-based core network functionality to enable one mobile phone number for multiple SIM based devices, such as wearables. With this solution, operators can provide voice services with the same mobile phone number as the smartphone also on wearables. This is being deployed in more than 10 Ericsson VoLTE-enabled operator networks in Europe, North America and Asia Pacific.

New popular wearables with cellular connectivity are being launched on the market, enabling consumers to communicate and be reached more easily.

The voice calling capability is enabled in new cellular-enabled wearables that include VoLTE capabilities, and with standard SIM-cards or software embedded SIM-cards. These devices can connect to the mobile network without having to tether via a smartphone. Moreover, if they are designed with the Multi-SIM call capabilities towards the operator’s mobile network, users can also make calls without having their smartphone nearby.

Cellular connected smartwatches and other wearables with operator voice services can be useful while playing sports, performing challenging physical activities or simply when you are on the go. It is also handy for young children who could lose their phone, and elderly people for connecting in case of emergency situations.

Ericsson’s Multi-SIM for voice calls functionality allows a mobile operator to offer a one number solution for multiple SIM based devices. I.e. a new wearable device can now share the mobile phone number already belonging to an existing smartphone subscription.

The Multi-SIM for voice calls functionality builds on the Ericsson VoLTE solution, and can be added as an upgrade to operators’ Ericsson enabled VoLTE networks, once Multi-SIM capable devices are available on the market and verified towards the operators’ networks.

Monica Zethzon, Head of Product Management Communication Services says: “We continue building new useful services for our installed base of VoLTE networks, to enable our customers to launch innovative consumer and enterprise communication services. With the new Multi-SIM for voice calls functionality, we support operators launching new attractive devices, which can also make high-quality operator voice calls anywhere, using the subscriber’s mobile phone number.”

Ericsson has developed a complete network solution for Multi-SIM voice calling functionality, building on its VoLTE solution based on IP Multimedia Subsystem (IMS), and Secure Entitlement. System integration services for Multi-SIM voice call deployments are also available. For operators that have Ericsson VoLTE /IMS deployed, it is a simple software upgrade to their network.

The solution is verified and pre-integrated with market leading devices, and the Ericsson solution will be adapted for more device types and brands, based on market demand, and as the device ecosystem evolves.
