Methods, systems, and devices for wireless communications are described. Some wireless communications systems may transition between a real-time texting (RTT) mode and a text teletypewriter (TTY) mode and vice versa, on a user equipment (UE). A UE may make a determine to transition between two texting modes while coordinating the transfer of text data between the different modes. Some wireless communications systems may also transition a UE between a packet switched network and a circuit switched network without loss of signal and consistent text data delivery during the communication without losing the text data during the transition between the two coverage areas. Transitioning between modes and networks may provide a user with interoperability and the benefit of conveniently switching between two modes without service interruption.

Service continuity of real-time text and teletypewriter modes

Systems and methodologies are described that facilitate supporting multiple access modes for a base station in a wireless communication environment. The base station can leverage hybrid, closed, or open access mode. A whitelist of a mobile device that successfully registers on the base station can be selectively updated to include a CSG ID of the base station. For example, the CSG ID of the base station can be added to the whitelist when the base station operates in closed access mode, while adding the CSG ID can be skipped when the base station operates in hybrid access mode. According to another example, the CSG ID can be selectively added based upon a received accept cause value. Additionally or alternatively, a CSG ID and an access mode indicator can be transmitted from a base station to a network node for implementing access control and/or paging optimization at the network node.

Support for multiple access modes for home base stations

Methods and apparatuses are provided for managing packet data network (PDN) connectivity for a device. PDN connectivity to a local gateway can be managed at an access point with which the device is communicating based at least in part on received PDN connectivity parameters. The PDN connectivity parameters can include access points, related closed subscriber groups, public land mobile networks, etc., from which a device can request a PDN connection. The PDN connectivity parameters can be specific for the device and/or for one or more access point names. In addition, a subscription server or other core network device can communicate the PDN connectivity parameters to the device and/or the device can receive PDN connectivity parameters as a result of a failed PDN connection attempt to an access point.

The disclosure provides for a user equipment (UE) to change from a first network to a second network for an internet protocol (IP) multimedia subsystem (IMS) call. Initially, the UE has a connection to a first network providing an IP address for the UE. The UE may receive, via the first network, a message indicating an incoming IMS call. The UE may transmit one or more IMS call setup messages on the first network at an IP layer. The UE may change the connection from the first network to a second network that uses a same identifier for the UE (e.g., the IP address). The UE may complete setup of the IMS call on the second network using the same identifier for the UE.

UE network mobility during IMS

One aspect of the present application provides a Category M apparatus that communicates over a communication network. The apparatus comprises a processor and an interface. The processor is configured to generate a message requesting registration of the apparatus with a core network, the message generated to include at least one header indicating a power saving mode capability of the apparatus. The processor is further configured to schedule sleep periods and wakeup times for the apparatus. The interface is configured to transmit the message to the core network. The interface is further configured to receive a response, from the core network, including one or more parameters and one or more timers established by the core network based at least in part on the power saving mode capability of the apparatus.

Methods and apparatus for negotiating network sip resources based on device capabilities

A person may utilize multiple connected devices, such as smart watches, user equipments (UEs), smartphones, tablet computers, and/or the like, which may each be assigned unique phone numbers. Operators may assign a common phone number to the multiple connected devices; however, the phone number is not used in the access stratum path of a radio access technology resulting in multiple paging procedures being performed for the multiple connected devices. In implementations, described herein, a first UE, such as a smartphone, may obtain paging information associated with decoding paging messages for a second UE, such as a smart watch. The first UE may use the paging information to decode a paging message of a combined paging cycle established for the first UE and the second UE, thereby obviating a need for multiple paging cycles for the first UE and the second UE.

Techniques for transporting messages for location services (LCS) are described. A Mobility Management Entity (MME) may have a location session with an Evolved Serving Mobile Location Center (E-SMLC) to provide location services for a User Equipment (UE). The UE may exchange LCS-related messages with the E-SMLC to obtain location services. In an aspect, LCS-related messages exchanged between the UE and the E-SMLC may be encapsulated in Non-Access Stratum (NAS) messages and transported via the MME and a base station. In another aspect, a routing identifier (ID) may be used to associate messages exchanged between the UE and the MME with the location session between the MME and the E-SMLC for the UE. Each NAS message exchanged between the MME and the UE may include the routing ID, which may enable the MME to associate each NAS message from the UE with the location session between the MME and the E-SMLC.
