Techniques and systems for recovering a communication session from a dedicated bearer failure are disclosed. For example, a P-CSCF node can determine that a dedicated bearer associated with a communication session has failed, and, in response, send a SIP message to a UE associated with the communication session, the SIP message causing the UE to refrain from sending SIP requests using a SIP INVITE method. The process may further include identifying a first network node associated with an identifier of the UE, the first network node comprising one of a PGW or a SMF, and sending an instruction to the first network node to dissociate the dedicated bearer from the communication session. This causes a new attach procedure to be performed by the UE to recover the session without session failure.

A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.

A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

A server of a fifth generation (5G) network can provide substantially real-time charges for a UE during fallback to another network. A Telephony Application Server (TAS) in an IP Multimedia Subsystem (IMS) can identify Evolved Packet System Fallback (EPSFB) and report the EPSFB to a charging system to cause the charging system to generate accurate charges for user equipment communicating over the 5G network and the other network. The TAS can comprise logic to identify a change in P-Access-Network-Information associated with each network, and generate a call detail records for billing, or real-time communication via an online charging and/or offline charging for the served UE. Information (a user profile, call detail records, instance of EPSFB, etc.) associated with the TAS can be used to make network improvements that decrease instances of EPSFB and increase an amount of new radio services available to UEs.

In some embodiments, a method includes: generating, by a session controlling Internet platform, a personalized Universal Resource Locator link (PURL), including: where the PURL is: communicatively coupled to the permission controlling schema and configured to be utilized to establish a peer-to-peer communication session between a sender computing device and a recipient computing device; where the PURL includes: a domain name associated with the session controlling Internet platform hosting a permission controlling schema, and at least one first identity linked to the recipient computing device; transmitting, by the session controlling Internet platform, the PURL to the recipient computing device; receiving, by the session controlling Internet platform, after the transmitting the PURL to the recipient computing device, a mobile originating communication, having data including: a multi-part multi-functional address signaling sequence, including: a MICRO band part, corresponding to a MICRO band parameter and a MACRO band part.

A data volume exchange server includes a terminal IF unit configured to receive an exchange request for a contract data volume of an own country and a contract data volume of another country from terminals of subscribers having contract data volumes of telecommunication carriers of countries different from each other, a data volume exchange unit configured to perform matching of a pair in which another country that requests a contract data volume in one of the received exchange requests matches the own country that provides a contract data volume in another of the received exchange requests, and a server IF unit configured to instruct the communication servers of the telecommunication carriers in the countries to transfer a contract data volume of a matched subscriber of the own country as an exchanged data volume of a subscriber of the other country who is a matching partner.

A processing system may maintain a communication graph that includes nodes representing a plurality of phone numbers including a first phone number and edges between the nodes representing a plurality of communications between the plurality of phone numbers and may generate at least one vector via a graph embedding process applied to the communication graph, the at least one vector representing features of at least a portion of the communication graph. The processing system may then apply the at least one vector to a prediction model that is implemented by the processing system and that is configured to predict whether the first phone number is associated with a type of network activity associated with a telecommunication network and may implement a remedial action in response to an output of the prediction model indicating that the first phone number is associated with the type of network activity.

A processing system may maintain a relationship graph that includes nodes and edges representing phone numbers and device identifiers having associations with the phone numbers. The processing system may obtain an identification of a first phone number or a first device identifier for a fraud evaluation and extract features from the relationship graph associated with at least one of the first phone number or the first device identifier. The plurality of features may include one or more device identifiers associated with the first phone number, or one or more phone numbers associated with the first device identifier. The processing system may then apply the features to a prediction model that is implemented by the processing system and that is configured to output a fraud risk value of the first phone number or the first device identifier and implement at least one remedial action in response to the fraud risk value.

A base station sends, to a wireless device, a system information block (SIB) indicating that restricted local operator services (RLOS) are supported by a public land mobile network, and receives, from the wireless device and based on the SIB indicating support for the RLOS, a preamble. The base station sends a random access response to the preamble and receives at least one first radio resource control (RRC) message comprising a first information element indicating that an RRC connection of the wireless device is for the RLOS and a second information element comprising an attach request message indicating, to a mobility management entity (MME) configured with an RLOS access point name, that an attach request of the wireless device is for the RLOS. The base station sends to the wireless device a second RRC message comprising an attach accept message indicating acceptance of the RLOS by the MME.

An IP Multimedia Subsystem Service Control Point (IMS-SCP) module of a carrier network may provide trigger management for a request for a circuit switched (CS) call. For example, an IMS-SCP module may receive an request for a CS call associated with a user equipment. The IMS-SCP module may determine handling of the request for the CS call includes one or more first operations by a first feature platform and one or more second operations by a second feature platform. In response to the determining, the IMS-SCP module may perform trigger management associated with the request for the CS call. The trigger management may include invoking, by the IMS-SCP module, the one or more first operations of the first feature platform and, subsequent to the invoking the one or more first operations, invoking the one or more second operations of the second feature platform.
