Systems and Methods for Improving Support for Data-Oriented Services in a Multi-Subscriber Identity Module (SIM) Wireless Communication Device Having a Designated Data Subscription (DDS)

Publication number: 20180132289

Abstract: A multi-subscriber identification module (MSIM) wireless communication device may have at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that the first SIM is set as a designated data subscription (DDS), such that a modem stack associated with the first SIM receives information broadcast by a first network. The wireless communication device may perform a network attach procedure with a second network on a modem stack associated with the second SIM, such that a default packet data network (PDN) connection is established with the second network. The wireless communication device may set the default PDN connection as a persistent PDN connection, with the modem stack associated with the second SIM maintaining at least one persistent PDN connection.
