Abstract: Various communication systems may benefit from suitable interworking. For example, certain fifth generation short message service systems may benefit from interworking with long term evolution short message service deployments in a visited public land mobile network. A method can include receiving, at a network element, an attach request from a user equipment. The method can also include using an internal policy to find a short message service function that resides at the network element. The method can further include using an address of the short message service function for providing short message service to the user equipment.

Abstract: A UE activates a PS Data Off service to block downlink and uplink services except the exempted services determined by the HPLMN. To activate PS Data Off, the UE sends an indication to the MME or SGSN, or additionally to a S-CSCF or an IMS network. The UE may receive a confirmation of the PS Data Off activation and/or a list of exempt services. The MME may contact the HSS to notify about the activation of the PS Data Off and receive indication of support of the service or list of exempted services and send the indication and/or packet filtering per PDN to PDN GW(s). The PDN GW may contact a PCRF to get policy rules. The HSS may provide a list of exempt services to the S-CSCF.

Abstract: Various communication systems may benefit from appropriate handling of messages. For example, certain fifth generation communication systems may benefit from short message service over non-access stratum with a home-routed model. A method can include receiving a request, at a short message service function, to associate an access management function to the short message service function. The method can also include accepting the request.

Abstract: Various communication systems may benefit from being able to communicate without requiring certain identifiers to be assigned. For example, certain wireless communication systems may benefit from machine type communication using mobile originated short messaging service without a mobile station international subscriber directory number. A method can include preparing, at a user equipment, a mobile originated short message service message. The method can also include identifying, in the message, a particular external identifier from a set of external identifiers assigned to an application.

Abstract: Apparatus and methods for streamlined cell activation in a wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which utilize bandwidth-efficient setup/configuration messaging and cell activation, including for very large numbers of cells, and which do not overwhelm data backhaul(s) associated with wireless nodes used for communication. In one embodiment, a message protocol is used wherein a prescribed number of cells of a given DU (e.g., all, a prescribed subset, etc.) are activated without having to enumerate or include specific data relating to the cells being activated. In one variant, this “global” activation is conducted using an Activate All Cells IE (Information Element) disposed with the F1SETUP RESPONSE message issued by a controlling CU entity within a 5G-NR infrastructure. In other variants, cells of multiple DUs can be controlled simultaneously, such as via distribution of a system-wide global activation IE.

Abstract: A cable communications network provides an alternative communications path between a user equipment device and a data network to a cellular path for a communications session with a desired level of Quality of Service. A cable modem termination system, coupled to a wireless core network, e.g., a 5G core network, interacts with the wireless core network to attempt to establish a PDU session for a UE with a desired QoS level. The core sends a QoS service request message to the CMTS including a requested level of QoS, an IP address and port number for the session. The CMTS and cable modem, corresponding to the UE, negotiate and decide if the request desired QoS level can be supported over the cable between the CMTS and the cable mode for the session.

Abstract: Various communication systems may benefit from improved voice call support. For example, it may be helpful for a user equipment in a first radio access technology that may not support voice calls to initiate a voice call with a second radio access technology. A method includes initiating a voice call between a user equipment to an entity in a second radio access technology cell. The user equipment is located in a first radio access technology cell. The method also includes registering the user equipment with the second radio access technology cell. In addition, the method includes conducting the voice call with the entity via the second radio access technology cell.

Abstract: Certain networks can operate using circuit switched infrastructure, while other networks may operate using infrastructure for the long term evolution (LTE) of the third generation partnership project (3GPP). Devices can operate across the boundaries of these networks. Thus, such devices as well as the networks may benefit from network sharing in reverse single radio voice call continuity. For example, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include providing a network identification corresponding to the source network while requesting the handover. Alternatively, or in addition, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include determining the target network based on a network identification received previously.

Abstract: Various communication systems may benefit from improved signaling. For example, certain communication systems may benefit from improved signaling before network access is revoked through a citizens broadband radio service. A method may include receiving at a network entity from a citizens broadband radio service device a warning message. The warning message may include a drop time after which communication between a network and a user equipment using the citizens broadband radio service will terminate. The method may also include triggering the performing of an action based on the warning message by the network before the drop time.
