Handover attempt made to better K-cell (only for the Ericsson 1 locating algorithm), I.e. Signal Strength.

Number of handover attempts due to bad downlink quality. There is one HO counter for bad uplink quality called HOUPLQA and one for excessive timing advance called HOEXCTA.

TOTCONGPAG BSC

Number of intra cell handover attempts (decisions) at bad quality on both links.

The counter (TOTPAG) counts the total number of PAGING messages received from the MSCThe counter (TOTCONGPAG) counts the number of discarded PAGING messages due to lack of capacity in the BSC or due to congestion in the BSC paging queues or due to no Data Link Individual is available for a paging request taken from the paging queue.

There is also a counter for all accepted random accesses (CNROCNT) that means all except failed random accesses. The counters RAANPAG and CNROCNT are also incremented for TRXT connections. The failed random access counter (RAACCFA) is incremented for a Random access received with too high TA, values that are not used or in case of 'software file congestion'. Answer to paging (RAANPAG). The counter will be stepped for cause value 100x xxxx.Call reestablishment (RACALRE). The counter will be stepped for cause value 110x xxxx, Call reestablishment, TCH/F is needed, or originating call and NECI bit not set to 1, or procedures that can be completed with an SDCCH and NECI bit not set to 1.Emergency call (RAEMCAL). The counter will be stepped for cause value 101x xxxx.Other service request (RAOSREQ). The counter will be stepped for cause value 111x xxxx, Originating call and TCH/F is needed, or originating call and the network does not set NECI bit to 1.All other cases (RAOTHER). The counter will be stepped for cause value 000x xxxx, Location updating (SDCCH needed).
