Abstract: A user equipment (UE) indicates to a network the types of SMS messages that the UE does not support. The network receives an indication from the UE corresponding to one or more types of short message service (SMS) messages that are supported by the UE, receives a SMS that is intended to be delivered to the UE, determines whether to forward the SMS message to the UE based on the indication received from the UE, when the SMS message is a type of SMS message supported by the UE, forwards the SMS message to the UE and, when the SMS message is not a type of SMS message supported by the UE, discards the SMS message.

Abstract: Apparatus and methods to support parallel access to services of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) by a wireless device are disclosed. The wireless device is a single-radio wireless device that includes wireless circuitry that supports an active voice or video connection via a single radio access network of a cellular wireless network at a time. To send or receive data for a second SIM/eSIM, when an active voice or video connection for a first SIM/eSIM uses the wireless circuitry, the single-radio wireless device can i) establish parallel, linked protocol data unit (PDU) sessions for different SIMs, ii) multiplex traffic for different SIMs over a common radio connection with SIM information embedded in protocol headers for routing by network equipment, and/or iii) use an additional dedicated bearer using a first, active SIM for each data network name (DNN) over which to route for a second, suspended SIM.

Abstract: Manners of controlling a data rate for a user equipment (UE) on a per slice basis by either a core network or a radio access network (RAN). In one exemplary manner, a request is received to establish a new Protocol Data Unit (PDU) session for a network slice for a user equipment (UE), a maximum session throughput value is received for the new PDU session, the maximum session throughput value for the new PDU session is added to an accumulated maximum session throughput value to determine an updated accumulated maximum session throughput value, the updated accumulated maximum session throughput value is compared to a maximum slice throughput value and, when the updated accumulated maximum session throughput value exceeds the maximum slice throughput value, an action is performed related to the new PDU session.

Abstract: A method performed by a station that includes receiving information from a cell of a Public Land Mobile Network (PLMN), determining whether the information indicates the cell supports circuit switched fallback (CSFB) voice calls, when the CSFB voice calls are not supported, determining whether at least one packet switched voice property of the station satisfies a predetermined condition and attaching to the cell of the PLMN when the predetermined condition is satisfied. A further method performed by a station connected to a PLMN that includes identifying cells of the PLMN available for the station to camp on, determining whether the station is capable of executing packet switched calls, when the station is not capable of executing packet switched calls, determining whether the identified cells have a neighbor cell that supports CSFB voice calls and prioritizing the cells that are identified as having neighbor cells that support CSFB voice calls.

Abstract: A method, station and computer readable storage medium used for location aware network selection. A station determines a geographic location of the station, determines at least one predetermined Public Land Mobile Network (PLMN) in the geographic location by comparing the geographic location to a database including stored geographic locations and PLMNs known to be present within each of the geographic locations, performs a targeted scan on select channels corresponding to the at least one predetermined PLMN to identify at least one available PLMN from among the at least one predetermined PLMN and selects one of the at least one available PLMN for the station to join.
Abstract translation: 用于位置感知网络选择的方法，站和计算机可读存储介质。 站确定站的地理位置，通过将地理位置与数据库进行比较来确定地理位置中的至少一个预定公共陆地移动网络（PLMN），数据库包括已知存在于每个地理位置内的存储的地理位置和PLMN 对与所述至少一个预定PLMN相对应的选择信道执行目标扫描，以从所述至少一个预定PLMN中识别至少一个可用PLMN，并且选择所述站要加入的所述至少一个可用PLMN中的一个。

Abstract: A user equipment (UE) is configured with operations to determine whether a network supports non-voice IP Multimedia Subsystem (IMS) services. The UE determines whether a network with which the UE is communicating supports a non-voice IP Multimedia Subsystem (IMS) service and when the network supports the non-voice IMS service, initiates an IMS Protocol Data Unit (PDU) session establishment with the network.

Abstract: A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.
