Abstract
A SRLTE/Hybrid CDMA management system is provided to facilitate the prioritization and management of shared RF resources among the different SIMs and RATs in a multimode device. The described techniques address a shared single RF resource usage problem in multi-SIM and multimode 3GPP2/3GPP devices that implement an SRLTE or Hybrid CDMA mode in one or more SIMs. Thus, the techniques enable the RATs within an SRLTE or Hybrid CDMA system, and RATs across multiple SIMs, to access a single set of RF resources using a priority access scheme that prioritizes RATs for both packet service (PS) and circuit service (CS).
Claims23
A device, comprising:
- a first subscriber identity module (SIM) configured to support a packet-service (PS) radio access technology (RAT) and a circuit-service (CS) RAT, the PS RAT and the CS RAT operating within one or more time-varying PS and CS communication substates, respectively, in accordance with a first communication protocol;
- and
- one or more processors configured to selectively assign a priority to the PS RAT and the CS RAT based upon a comparison of a current PS communication substate to a current CS communication substate from among the time-varying PS and CS communication substates that are associated with the CS RAT and the PS RAT, respectively, and to allow one of the PS RAT or the CS RAT access to an RF resource in accordance with the assigned priority.
A device, comprising:
- a plurality of subscriber identity modules (SIM), a first subset of the plurality of SIMs being configured to support a packet-service (PS) radio access technology (RAT) and a circuit-service (CS) RAT as defined by a first cellular communication protocol, and a second subset of the plurality of SIMs being configured to support a CSPS RAT as defined by a second cellular communication protocol;
- and
- one or more processors configured to iteratively compare a current communication substate of one or more of the PS RATs, the CS RATs, and the CSPS RATs associated with the plurality of SIMs, to prioritize each SIM from among the plurality of SIMs based upon the comparison of current communication substates, and to allow a SIM from among the plurality of SIMs having the highest priority access to a single RF resource that is shared among each of the plurality of SIMs using one of a PS RAT, a CS RAT, or a CSPS RAT.
A non-transitory computer readable medium having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to:
- operate a wireless communication device using a first SIM that supports packet-service (PS) radio access technology (RAT) and circuit-service (CS) RAT, the PS RAT and the CS RAT operating within one or more time-varying PS and CS communication substates, respectively, in accordance with a first communications protocol,
- operate the wireless communication device using a second SIM that supports a CSPS RAT, the CSPS RAT operating within one or more time-varying CSPS communication substates in accordance with a second communications protocol, and
- selectively assign a priority to each of the PS RAT, the CS RAT, and the CSPS RAT based upon a comparison of a current PS communication substate, a current CS communication substate, and a current CSPS communication substate from among the time-varying PS, CS, and CSPS communication substates that are associated with the PS RAT, the CS RAT, and the CSPS RAT, respectively, and to allow one of the PS RAT, the CS RAT, or the CSPS RAT access to a single RF resource that is shared among the first SIM and the second SIM based upon the assigned priority.
