Abstract: A method for handling IMS registrations at a P-CSCF after PCRF database failure includes receiving a SIP REGISTER request message after a PCRF database failure and determining that the SIP REGISTER request message is for an existing user. The method further includes obtaining a list of user contacts having entries in a registration cache of the P-CSCF corresponding to an address of record in the SIP REGISTER request message, testing reachability of the user contacts in the list, and freeing resources of the P-CSCF for the user contacts determined to be unreachable.

Abstract: Methods, systems, and computer readable media for a multi-view data construct that supports lock-free operations and direct access are disclosed. According to one aspect, a system includes a multi-view data construct including a persistent collection of elements, each element being associated with a unique identifier. Each element includes at least one pointer for configuring the element as a member of a linked list that contains as members elements of the multi-view data construct, data that indicates access status, and a data area within the collection itself or a pointer to a statically or dynamically allocated data area outside of the collection. A control module can identify elements in the collection by each element's respective identifier and can traverse elements in the collection using the pointers contained in each element. Concurrent access to an element by multiple entities is mediated using that element's access status and without using locks or locking operations.

Abstract: Methods, systems, and computer readable media for providing a workload balancer for balancing message traffic received over long-lived Diameter connections are disclosed. One exemplary workload balancer includes at least one connection front end processor for terminating Diameter connections with external nodes. The workload balancer further includes a plurality of Diameter back end processors for performing application or routing processing for the Diameter messages received over the Diameter connections. The at least one connection front end processor load shares Diameter messages received over existing Diameter connections among the back end processors.

Abstract: A method for identifying session contexts for handling spiral calls includes, at a SIP session manager, receiving, from a first node, a first SIP request message. The method further includes determining that the first SIP request message is a request for establishing a new session or subscription. The method further includes, in response to determining that the first SIP request message is a request for establishing a new session or subscription, generating a first unique identifier. The method further includes using the first unique identifier as or to generate a first session context identifier. The method further includes creating a first session context database record for the first session or subscription. The method further include inserting the first unique identifier in a Record-Route header. The method further includes adding the Record-Route header to a first outbound SIP request message and routing the first outbound SIP request message.

Abstract: Methods, systems, and computer readable media for routing of packets for lawful interception (LI). A system includes at least one session border controller (SBC) configured for forwarding media streams to a forwarding function. The system includes the forwarding function, implemented on a centralized node for a telecommunications network. The forwarding function is configured for receiving the media streams and forwarding each media stream to a respective lawful intercept mediation server for at least one country associated with the media stream. The forwarding function is configured for, in response to receiving a first packet of a first media stream from the SBC, performing a destination lookup for the first media stream and sending a mediation server identifier for the first media stream to the SBC. The SBC can be configured for sending a session release indicator and a direction flag to the forwarding function.

Abstract: A first SBC establishes a first media session between a transferor and a transferee. A second SBC establishes a second media session between the transferor and a transfer target. The first SBC receives a REFER message initiated by the transferor and determines that a dialog ID in the REFER message does not correspond to a media session currently being handled by the first SBC. The first SBC sends a SIP INVITE message to a plurality of SBCs, including the second SBC, that are in a load sharing group with the first SBC. The SIP INVITE message includes the dialog ID associated with the second media session, which triggers the second SBC to re-use the second media session to establish a media session between the transferee and the transfer target.

Abstract: Methods, systems, and computer readable media for restoration of Diameter connectivity. An example method includes accepting a first Diameter connection with a Diameter client having a Diameter identifier. The method includes receiving a request to establish a new Diameter connection with the Diameter identifier. The method includes holding the request to establish a new Diameter connection for a specified time limit, and, while holding the request, probing the first Diameter connection to determine whether the first Diameter connection has been broken. In response to determining that the first Diameter connection has been broken, the method includes aborting the first Diameter connection and accepting a second Diameter connection with the Diameter client having the Diameter identifier.
