A device may detect a communication session between a user equipment and a network. The device may cause, based on detecting the communication session, a set of queries to be transmitted to a plurality of control plane nodes of the network. The device may determine, based on a set of responses associated with the set of queries, respective characteristics for corresponding control plane nodes, of the plurality of control plane nodes. The device may determine, based on the respective characteristics, scores for the corresponding control plane nodes, wherein the scores are representative of respective capabilities of the corresponding control plane nodes to be used for the communication session. The device may select, based on the scores, a control plane node, from the plurality of control plane nodes, for the communication session. The device may configure the control plane node to perform a control operation for the communication session.

Systems and methods for detecting control plane node availability

A device may attach to a mobile service provider (MSP) network and establish a first communication path from the device to a packet data network (PDN) gateway in the MSP network. The device may also start a session over the first communication path and detect a wireless network which is available for establishing a second communication path that extends from the device to the PDN gateway over the wireless network. While the first communication path is intact, the device may: attach the device to the MSP network over the wireless network, wherein attaching the device over the wireless network includes establishing a second communication path from the device to the PDN gateway over the wireless network; evaluate conditions for the first communication path and the second communication path; and select one of the first and second communication paths as an active communication path based on the evaluated conditions.

A method, a device, and a non-transitory storage medium provide storing context information pertaining to an end device and previous attachments of the end device to the network; receiving an indication that the end device requests an attachment to the network subsequent to the storing and subsequent to previously occurring detachments of the end device; authenticating the end device using the context information during the attachment; and causing a creation of a bearer connection between the end device and the network using the context information and during the attachment.

System and method for reattachment to a network

A system includes a wireless access network, a gateway that controls communications between the wireless access network and a packet data network, and a policy-charging-and-rule-function (PCRF). The PCRF includes a routing agent in communication with the gateway and a group of multi-media processing engines (MPEs) that are associated with the routing agent. The routing agent receives from the gateway a request to establish a session for a piece of user equipment, and selects one of the MPEs to handle the session based on an IMSI of the piece of user equipment. The routing agent maintains a table indexed by IP address, and makes an entry therein that points to the selected MPE.

A shutdown notice may indicate that a primary CCF system is expected to shutdown soon. This notice may be received by a CTF system after the CTF system delivers an ACR Start message to the primary CCF system, but before it delivers an ACR Stop message relating to the same chargeable session to the primary CCF system. In response to this shutdown notice, the CTF system may be configured to deliver an ACR Stop message relating to the same chargeable session to the primary CCF system before the primary CCF system shuts down. Also in response to this shutdown notice, the CTF system may be configured to deliver an additional ACR Start message and an ACR Stop message relating to the same chargeable session to a secondary CCF system.
