A tibial prosthesis has a bearing component configured for an anterior-medial insertion, which advantageously avoids the extensor mechanism of the knee. For instance, the techniques may calculate transaction latencies for a given session based on the time between sending requests for content receiving the requested content. The target PDSN, upon receiving a registration request for the temporary IP address from the mobile terminal moved to its service area, temporarily registers the temporary IP address in an IP pool. A correction value is determined based on the associated specific phase and on a specific allocated phase.
