  • Publication number: 20230319690
    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a scan reduction associated with legacy RATs. A UE may receive, from a database, an indication that a first RAT is unavailable for communications associated with a PLMN. The indication that the first RAT is unavailable may be based on one or more unsuccessful scans for the first RAT. The UE may scan for a second RAT based on a skipped scan for the first RAT. The skipped scan may be based on the indication that the first RAT is unavailable. The UE may communicate with the PLMN based on the scan for the second RAT and the skipped scan for the first RAT.

  • Publication number: 20230189371
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently falling back from one RAT to another RAT while maximizing the services available to a UE. When a request from a UE for communicating with a base station using one RAT is rejected by a network node for unexpected causes, the UE may use the techniques described herein to fallback to an appropriate RAT. For instance, after receiving a response indicating that a request including fifth generation (5G) parameters is rejected, the UE may drop the 5G parameters and fall back to fourth generation (4G), rather than falling back to second generation (2G) or third generation (3G). The unexpected causes may be preconfigured and may be determined based on a number of factors, including a subscription of the UE, a public land mobile network (PLMN) associated with the network node, etc.

  • Patent number: 10757622
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive a priority list associated with preferred radio frequencies from a serving base station. In certain aspects, each radio frequency of the preferred radio frequencies associated with a first set of base station may operate on a first RAT. In certain other aspects, the apparatus may determine if the UE is able to reselect to the first RAT. In certain other aspects, the apparatus may perform a rank-based cell reselection procedure based on signal strength when the UE is unable to reselect to the first RAT.

  • Publication number: 20180063774
    Abstract: Various methods for performing public land mobile network (PLMN) searches on a mobile communication device may include obtaining information about one or more radio access technologies (RATs) for which network coverage is allowed by a network operator of a home PLMN (HPLMN) of the mobile communication device, selecting one of the one or more allowed RATs, conducting a PLMN search on the selected RAT, and determining whether there are available PLMNs on the selected RAT based on the PLMN search. In some examples, the information about one or more RATs for which network coverage is allowed by the network operator may be stored in a universal subscriber identity module (USIM) on the mobile communication device. In such example, the information may be stored in one or more PLMN selector lists on the USIM.

  • Patent number: 9706377
    Abstract: A method for supporting emergency cell broadcast (CB) messages on a multi-subscriber identity module (SIM) mobile communication device includes: waking up a first subscription from a sleep mode at a common traffic channel (CTCH) occasion; decoding a CB message header received during the CTCH occasion; determining whether a scheduling message (SM) is present based on the decoded CB message header; and in response to determining that the SM is present, granting resource priority to the first subscription to decode the complete SM.

  • Publication number: 20170111512
    Abstract: Aspects of the present disclosure provide an apparatus and techniques for wireless communication by a user equipment (UE), such as placing a video telephony (VT) call when a user equipment (UE) is camped on a non-Internet Protocol Multimedia Subsystem (IMS) network, such as a non-IMS Long Term Evolution (LTE) network. The UE may be in a coverage area of a first radio access technology (RAT) supported by a first standard, and in a coverage area of a second RAT supported by a second standard. The UE may determine the LTE network does not support IMS services. In response to the determination, the UE may take one or more actions to place a VT call using the second RAT which supports IMS services.

  • Patent number: 9578473
    Abstract: A method for selecting a subscription to receive cell broadcast service (CBS) messages for a multi-subscriber identity module (SIM) mobile communication device may include: camping on a first communication network with a first subscription; camping on a second communication network with a second subscription; determining whether system information blocks (SIBs) received on the first subscription and the second subscription contain information elements including one or more parameters that define a broadcast multicast control (BMC) scheduling message (SM) period; in response to determining that the SIBs received on at least one of the first subscription and the second subscription contain the information elements including the one or more parameters defining the BMC SM period, selecting the one of the first subscription and the second subscription associated with the SIBs containing the information elements to receive the CBS messages.

  • Patent number: 9408052
    Abstract: Techniques are described for power conservation in emergency broadcast message reception in a wireless communications system. In accordance with a method for conserving power, one or more segments of an emergency broadcast message in an access stratum are received. The emergency broadcast message is identified as a duplicate emergency broadcast message based at least in part on one or more identifiers of the received one or more segments. The receipt of additional segments of the emergency broadcast message is terminated.

  • Publication number: 20160112907
    Abstract: User equipment (UE) based pseudo-reselection occurs from a first wireless cell to a second wireless cell. A UE autonomously discovers candidate reselection frequencies and autonomously sets reselection thresholds. The UE perform cell reselection based on the discovered candidate cell reselection frequencies and the autonomously set thresholds.

  • Publication number: 20160057661
    Abstract: To leverage the potential advantages of configuring an LTE radio access technology (RAT) to acquire services in a CSFB mode, methods implemented in a mobile communication device (e.g., a simultaneous GSM/LTE+GSM communication device) determine whether an available network is capable of supporting circuit-switch fallback (CSFB) operations for the LTE RAT and configure the LTE RAT to acquire services in either a CSFB mode or an SGLTE mode based on the network's capabilities. In response to determining that the mobile communication device has entered a new tracking area in the LTE RAT's network, a mobile communication device processor may determine whether a network available in the new tracking area supports CSFB operations and may configure the LTE RAT to operate in either a CSFB mode or an SGLTE mode based on that determination, thereby potentially improving the LTE RAT's overall performance and quality of services.
