An IP short message gateway (IP-SM-GW) utilizes multiple addresses for delivering short messages between an IP network and a cellular network. The IP short message gateway can have multiple SCCP addresses that correspond to categories of origin/destination IP addresses of short messages. In response to a request to deliver a short message between an IP network and a cellular network, the IP short message gateway identifies an IP address associated with the origin/destination of the short message. The IP short message gateway then identifies at least one of its multiple SCCP addresses based on the identified IP address. The IP short message gateway can generate a response message that includes the identified SCCP address. The identified SCCP address in the response message will be available to SMSC or IMS. SMSC or IMS can implement differentiated handling of short messages based on SCCP addresses received from the IP short message gateway.

Techniques for a selection or reselection a user-plane path in a mobile network are disclosed herein. A user-plane gateway (GW-U) can be configured to decode a packet received from a control plane gateway (GW-C) in a packet data network gateway (PGW) to determine a forwarding policy. Additionally, the GW-U can decode, from an evolved node B (eNB), an internet protocol (IP) packet having a header field. Furthermore, the GW-U can determine a user-plane path for the IP packet based on a comparison of the header field and the forwarding policy. Based on the determined user-plane path, the GW-U can forward the IP packet to a local application server (AS), encapsulate and forward the IP packet to the PGW, or discard the IP packet. Moreover, the GW-U can encode the IP packet for transmission based on the determined user-plane selection.

The disclosed systems and methods provide organization, small group, and particularly family-oriented communications platforms, with computing device applications and services allowing users to post, store, organize and share transactions, events, stories, updates, conversations, photos, physical location information and videos and other small group shared, or family-related, information within specified small group units, including specified family units. A content-controlled data and information exchange environment, as a local unit network, is provided that effectively firewalls content providers from gaining insight into the information exchanged by, and preferences of, any individual member of the group, while maintaining transparency into the interests, goals, objectives and data exchange preferences of the group. These objectives are implemented via a specific communications gateway between the local group network and external communication nodes.

The embodiments herein relate to a method in a Policy and Charging Rules Function, PCRF, node (208) for handling Access Point Names, APNs. The PCRF node receives, from a Core Network, CN, node (205), a request message comprising information indicating a first APN associated with a packet data connection. The request message is a request for a second APN being configured for a wireless device (203) arranged to communicate via the packet data connection. The PCRF node selects a configuration for the wireless device (203), and selects the second APN adapted to the selected configuration from a plurality of candidate second APNs. Each candidate second APN in the plurality comprises different configurations for the same packet data connection. The PCRF node transmits a response message to the CN node (205). The response message comprises information indicating the selected second APN.

A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines estimated location of the wireless-enabled personal locator device with time of arrival modeling.

A computing device, such as a mapping application server, may track data associated with a plurality of user devices, such as an Internet Protocol version. A system, such as an IMS system, may use may use the data associated with the plurality of user devices to process messages. When messages between devices are received, the computing device may provide information regarding at least one protocol associated with a communication. The computing device may respond to queries from various network elements. The responses may provide data that may be used to identify a protocol version, such as a Name Authority Pointer (NAPTR). Any necessary protocol interworking may be provided by the system.

Methods, systems, and apparatuses for discovering dynamic path maximum transmission unit (PMTU) between a sending computing device and a receiving computing device (e.g., a client device and a host device) are described herein. A sending computing device may iteratively transmit bursts of probe packets, each burst being defined by a search range between a maximum packet size and a minimum packet size. The sending computing device may iteratively update the search range based on the previous iteration until the search converges on the PMTU. When the PMTU is discovered, each of the computing devices may update their transport and presentation layer buffers based on the discovered PMTU without any other protocol level disruption. In a multi-path scenario, the computing device may discover PMTU for each of the paths and select a performance optimal path based on the individual PMTUs and other network characteristics such as loss, latency, and throughput.

A gateway device includes a communication unit communicating a frame signal conforming to an IuUP (Iu User Plane) protocol with a wireless base station controller connected to a circuit switching network; a determination unit determining whether the frame signal received by the communication unit satisfies a predetermined condition or not; a conversion unit converting information included in the frame signal to information to be set in a flow control signal of an IMS (IP Multimedia Subsystem) when the frame signal satisfies the predetermined condition; and a flow control signal transmission unit transmitting the flow control signal to a communication device in the IMS.

Users receiving incoming messages may provide their preferences for how they wish to be notified of the incoming messages. A plurality of user devices may be caused to output indicators of the incoming messages, and at least one of the user devices may also provide an acknowledgement of the notification, and the indicators may be cleared.

The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding IMS (Internet Protocol Multimedia Subsystem) restoration support for temporary GRUU (Globally Routable User Agent Uniform Resource Identifier). Certain aspects of the present invention include creating, at a registrar, a registration identified by a registration identifier, and storing, by the registrar, the registration identifier, a call identifier and an initial command sequence related to the registration identified by the registration identifier in a persistent database during the registration.
