Various embodiments include a wireless communication network that comprises network circuitry. The network circuitry executes a policy controller, session controller, and binding data store. The policy controller detects a session binding request failure to a binding data store and indicates a retry timer to the session controller that manages a session for a wireless user device. The policy controller provides network policies to the session controller for the session of the wireless user device. The policy controller receives a policy update request from the session controller in response to expiration of the retry timer. The policy controller transfers a session binding request to the binding data store. The binding data store receives the session binding request and stores a session binding that associates the policy controller and the wireless user device.

Existing session routing strategies tend to primarily focus on performance and cost efficiency, with less emphasis on energy consumption or sustainability. To address this, devices, systems, methods, and processes that facilitate sustainability-aware collaboration session activity routing are described herein. A session control logic receives attributes of a plurality of network devices and determines sustainability scores for the plurality of network devices. The session control logic further selects a target network device from the plurality of network devices based on the sustainability scores, and directs a collaboration session activity to the selected target network device. Thus, the target network device receives the collaboration session activity in response to its sustainability score being optimal in comparison to respective sustainability scores of peer network devices. As a result, the session control logic explicitly considers sustainability impact of a routing decision when determining routes, leading to improved energy efficiency or reduced environmental impact.

Solutions are disclosed that provide for internet protocol (IP) multimedia subsystem (IMS) session continuity with stored authentication. When a user equipment (UE) registers with a first proxy call session control function (P-CSCF), the first P-CSCF stores authentication information for the UE, and binding information for an IMS session in an authentication database, for example in a storage area network (SAN). Upon an outage of the first P-CSCF, a second P-CSCF (in the same pool) retrieves the authentication information and binding information in lieu of requiring the UE to register. The second P-CSCF is then able to act as a proxy for the IMS session. This is available for mobile originating (MO) and mobile terminating (MT) calls. For MO calls, the call setup is sped up. For MT calls, the UE is able to receive the call, rather than the call being missed.
