Aspects of this disclosure are directed to a method of routing text messages to subscribers of toll-free numbers using the toll-free exchange. Typically, an originating texter will draft a text message, using, for example, an SMS component of a cellular phone to a toll-free subscriber. In an aspect of the present disclosure, the text message is sent to the originating texter's service provider, which then routes the text message to the toll-free exchange. The toll-free exchange looks up the RESPORG ID associated with the ten-digit toll-free number, and the RESPORG ID is used for text message routing.

A central routing function (CRF) platform. The CRF platform comprises at least one processor; a non-transitory memory communicatively coupled to the at least one processor that stores a plurality of prioritized international call route lists where each prioritized international call route list associates alternative international communication service carrier routes in a prioritized order with an international telephone number; and a call process application stored in the non-transitory memory that, when executed by the processor, receives a request for a prioritized international call route list from a network element, where the request comprises an international telephone number, pads out the international telephone number received from the network element to form a 15-digit number, looks up a prioritized international route list using the 15-digit number in the non-transitory memory, and sends the prioritized international route list to the network element.

A method including: receiving one or more datasets indicating call activity corresponding to a phone number; analyzing the one or more datasets to identify unusual call activity; and generating a fraud prediction, based at least in part on the identified unusual call activity, that the phone number will be used for fraud.

A method is performed by a first node, such as a PCF node, of a telecommunication network is provided. The method includes providing an alternative charging profile and an alternative QoS profile to a second node, such as a SMF node, as part of a policy and charging, PCC, rule. The method also includes requesting the second node to apply charging from the PCC rule according to the alternative charging profile based on a QoS degradation. A method performed by a second node also is provided.

The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.

Apparatuses and methods for policy based selection of a network. In one embodiment, a method implemented in a user equipment (UE) includes obtaining a transfer policy from a policy node of a first network, the transfer policy being associated with a network selection for an application; and determining whether the application is to be transferred from using the first network to using a second network based at least in part on the obtained transfer policy, the first network being one of a standalone non-public network, SNPN, and a public land mobile network, PLMN and the second network being another one of the SNPN and the PLMN and the transfer policy being based at least in part on at least one of: (i) Quality-of-service, QoS, information associated with the application and (ii) whether the UE has a subscription to the second network.

A method for setting a policy for Over-The-Top (OTT) calls in a mobile network is provided. The method includes determining whether a cell of the mobile network has at least one neighboring cell of at least one roaming partner of the mobile network, and determining a bearer policy for routing OTT calls in the cell based on whether the cell is determined to have the at least one neighboring cell of the at least one roaming partner. The determined bearer policy indicates whether the OTT calls in the cell are to be routed on a dedicated bearer or a default bearer for connecting to an Internet Access Point Name (APN).

An inmate communication system and method of using are described herein for obtaining a lowest session rate. The inmate communication system includes a session boarder controller (SBC) server that analyses data from multiple carriers, historical sessions, and additional factors such as quality of service to determine a lowest rate for the session. The SBC server then routes the session using the carrier that has the determined lowest rate for the session. Further, the SBC server is configured to include both local and location redundancies to avoid interruptions in session service.

A method performed by a device for determining a subscriber identification module (SIM) card to be used for a call is provided. The method includes determining, for each of plural call types and prior to a new call originating from a user equipment (UE), a SIM card to be used, from among a first SIM card installed in the UE and a second SIM card installed in the UE, identifying a call type of the new call originating from the UE, selecting, based on the identified call type, the SIM card previously determined for the identified call type according to the determining, and updating, based on performance of the new call and prior to a subsequent call, the determined SIM card for at least one of the plural call types.
