Abstract

fetched live from OpenAlex

Mobility management architectures for future generations of PCS systems have been proposed where multiple location databases, organized in a tree, are used to cope with the large number of users. We have previously proposed the use of caching as an auxiliary strategy for reducing the network impacts of locating mobile users in a tree-structured architecture. In this paper we quantify the costs and benefits of caching for one particular variation of a caching strategy, called eager caching. Unlike our previous work where we only considered the user's calling and mobility behavior in terms of the aggregated regional call-to-mobility ratio (RCMR), in this paper the performance evaluation is done in terms of the local call-to-mobility ratio (LCMR) of the user. We show that under certain assumptions an eager caching strategy for users whose LCMR exceeds 5 can result in substantial reductions in total network cost as well as call setup time.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
