Abstract: In some implementations, a terminal, e.g., of a wireless telecommunications network, can receive information of at least two anchoring devices. The terminal can commence respective transactions with the anchoring devices via the network and determine that the respective transactions have failed. The terminal can then receive information of an additional anchoring device and commence a transaction with the additional anchoring device. In some examples, the terminal can commence transactions with a first anchoring device, then a second anchoring device in response to a transaction failure, then with the first anchoring device again in response to another transaction failure. In some examples, the terminal can commence a first transaction with the first anchoring device and determine that the first transaction has failed. The terminal can commence another transaction with the second anchoring device in response to an error reply, or with a third anchoring device in response to a timeout.

Abstract: An access network can allocate a bearer for a network service associated with a quality-of-service (QoS) value (QV) and a retention-priority value (RPV), and determine a bearer ID for the service based on the QV, the RPV, and a supplemental priority value (SPV) different from the QV and from the RPV. Upon handover of a terminal, session(s) carried by a bearer allocated by the terminal can be terminated. That bearer can be selected using IDs of the bearers and a comparison function that, given two bearer IDs, determines which respective bearer should be terminated before the other. Upon handover of a terminal to an access network supporting fewer bearers per terminal than the terminal has allocated, a network node can select a bearer based on respective QVs and RPVs of a set of allocated bearers. The network node can deallocate the selected bearer.

Abstract: Multiple communication session requests received by a terminating UE within a period of time can be handled on a last come, first served basis. A terminating UE that is in the process of setting up a first communication session, upon receiving a session request to establish a second communication session, is configured to terminate first setup procedures for the first communication session, and initiate second setup procedures to establish the second communication session. The last come, first served treatment of a subsequent communication session can be implemented unconditionally, or selectively by evaluating whether a condition is met prior to accepting the subsequent communication session before finishing setup procedures for the initial communication session.

Abstract: One or more timers can be used by an originating UE during setup of a communication session. The timer(s) can be triggered by an originating UE sending a request or receiving a response that uses a first signaling protocol. The timer(s) can further be terminated by the originating UE sending a request or receiving a response that uses a second signaling protocol different from the first signaling protocol, so long as the request/response using the second signaling protocol occurs before timeout of the timer(s).

Abstract: Transcoder assignment for real-time text (RTT) is described. A service provider can send an offer to establish a RTT call with a first device to an alternate service provider associated with a second device. The alternate service provider can transmit the offer to the second device, which can decline the offer. The alternate service provider can receive a response indicating that the second device declined the offer and, based on receiving the response, can determine whether the second device supports RTT. If the second device does not support RTT, the alternate service provider can add an indictor to the response that indicates that the second device does not support RTT. The alternate service provider can send the response (and the indicator) to the service provider, and the service provider can establish the RTT call without assigning a transcoder to the RTT call.

Abstract: Text content may be exchanged in a real time text (RTT) message during setup of, and prior to establishing, a primary communication session over a telecommunications network. An originating UE, upon receiving user input requesting to establish a primary communication session, may send, over a telecommunications network, a session request to establish the primary communication session. Prior to establishing the primary communication session, however, and during an early media communication session, the originating UE may send text content in a RTT message, and may establish the primary communication session after sending the text content in the RTT message.

Abstract: An originating user equipment (UE) that initiates a communication session as a real time text (RTT)-based communication may be configured to automatically downgrade the communication session in response to identifying one or more attributes of a response to a session request that indicate a communication session cannot be established with a full set of features requested by the user. For example, the originating UE can determine that a response to a session request indicates at least one of (i) an inability to establish the communication session, or (ii) an ability to establish the communication session without support for the exchange of the non-voice content via the RTT media stream. Based on this determination, a communication session can be established that does not support the exchange of the non-voice content via the RTT media stream. In this manner, rich RTT features are sacrificed in order to connect the user.

Abstract: The systems, devices, and methods discussed herein are directed to a network for delivering to portable communication devices, or user equipment (UEs) subscribed to the network, an update for an install service, such as software and firmware, via a hybrid transport mechanism. The hybrid transport mechanism comprises initially broadcasting the update to multiple UEs simultaneously, then re-broadcasting, multicasting, multiple unicasting, and/or transmitting via a wireless local area network (WLAN), the update to a group of UEs that missed the initial broadcast and/or needing file repairs.

Abstract: One or more timers can be used by an originating UE during setup of a communication session. The timer(s) can be triggered by an originating UE receiving a response from a node of a telecommunications network. The timer(s) can further be terminated by a particular termination event during a remainder of the session setup, so long as the termination event occurs before timeout of the timer(s).

Abstract: A P-CSCF (Proxy Call Session Control Function) is a component that services as an entry point into an IMS (IP multimedia subsystem) communications system. During a P-CSCF discovery process, a device is configured to obtain both an identification of a primary P-CSCF and an identification of a secondary P-CSCF. When initiating an IMS data session, a device first attempts to set up the session by communicating with the primary P-CSCF. If that fails, the device then attempts to set up the session by communicating with the secondary P-CSCF.
