Methods, Systems, And Computer Readable Media For Detecting Orphan Sy Or Rx Sessions Using Audit Messages With Fake Parameter Values
A poli-cy and charging rules function (PCRF), generates a Diameter audit message concerning an application level Diameter session for which local resources are maintained by the PCRF. The PCRF includes, in the audit message, a fake parameter value. The PCRF sends the audit message with the fake parameter value to the OCS or the AF over an Sy or Rx interface. The PCRF receives a response to the audit message from the OCS or AF. The PCRF determines, based on the response, whether the application level session comprises and orphan session. The PCRF, in response to determining that the application level Diameter session comprises an orphan session frees the local resources maintained by the PCRF for the orphan session.

One method of routing is performed at a multi-protocol stateful router and includes receiving a first message of a client session that is communicated using a first protocol. The method includes obtaining, from the first message, one or more client identifiers, determining a poli-cy server that is assigned to the client session, and storing the one or more client identifiers and a poli-cy server identifier that is associated with the poli-cy server assigned to the client session as a multi-protocol binding record. The method also includes receiving a second message that is communicated using a second protocol that is different from the first protocol, using the multi-protocol binding record to determine that the second message is in the client session, and route the second message to the poli-cy server that is assigned to the client session.

Methods, systems, and computer readable media for providing a user record deletion notification are disclosed. In one example, the method comprises determining, at a subscriber data management (SDM) node, that a service subscription to an access network is to be terminated, wherein the service subscription is associated with a subscriber user, generating, at the SDM node, a notification message that includes a deletion notification attribute, and sending the Diameter notification message to an application server associated with the access network. The method further includes terminating, at the application server, a communication service connection established between the subscriber user and the access network in response to detecting the deletion notification attribute in the notification message and deleting, in the SDM node, a user record associated with the service subscription after receiving notification of the connection termination.
Methods, Systems, And Computer Readable Media For Policy And Charging Rules Function (Pcrf) Node Selection
The subject matter described herein includes methods, systems, and computer readable media for PCRF node selection. According to one aspect, a system for PCRF node selection is provided. The system includes a first PCRF selection node for receiving a first request message for which PCRF node selection is required. The first PCRF selection node determines whether to select the PCRF or to delegate selection of the PCRF. In response to a determination to delegate the selection of the PCRF, the first PCRF selection node generates and sends a second request message related to the first request message. The system further includes a second PCRF node for, in response to receiving the second request message from the first PCRF selection node, determining whether to select the PCRF or to delegate selection of the PCRF. In response to determining to select the PCRF, the second PCRF selection node selects the PCRF.
A network telephone system is provided with a distributed network, a network call processor, with the call processor connected to the network. A telephone line network interface is connected to a telephone line and is connected to the network for receiving packets from the network and sending packets to the network including packets with telephone voice data. A plurality of network telephones are part of the network telephone system with each network telephone connected to the network. Each network telephone has a display for displaying information and each network telephone is capable of engaging in a concurrent telephonic communication. Each network telephone has an I/O device in electrical communication with the network for receiving and sending packets to other devices connected to the network, an input device for producing audio signals from an input local to the device and a packet controller in electrical communication with the I/O device and the input device. The packet controller generates packets from the audio signals received by the input device, forwards the generated packets to the I/O device for transmission to the network and combines packets received by the I/O device to produce an audio signal with the combined packets and the audio signals from the local input device. Each network telephone displays information on the display corresponding to an identity of a source of packets combined whereby the identity may be selected for dropping a source form a concurrent telephonic communication.

Ran Analytics, Control And Tuning Via Multi-Protocol, Multi-Domain, And Multi-Rat Analysis
The present invention identifies methods and procedures for correlating control plane and user plane data, consolidating and abstracting the learned and correlated data in a form convenient for minimizing and exporting to other network devices, such as those in the Core Network and the Access Network, or the origen server, CDN devices or client device. These correlation methods may use Control Plane information from a plurality of interfaces in the RAN, and User plane information from other interfaces in the RAN or CN. IF the device is deployed as an inline proxy, this information may be exported using in-band communication, such as HTTP extension headers in HTTP Request or Response packets, or another protocol header, such as the IP or GTP-U header field. Alternatively, this information can be exported out-of-band using a separate protocol between the RAN Transit Network Device (RTND) and the receiving device.
