HO_ALGO_HCS_SPEED_EST_SWITCH: When the switch is on, the RNC evaluates the UE's moving speed in the HCS and initiates fast intra-layer or slow inter-layer handover. 2. HO_ALGO_LDR_ALLOW_SHO_SWITCH: When the switch is on, the LDR inter-frequency handover is allowed during soft handover. 3. HO_ALGO_MBMS_FLC_SWITCH: When the switch is on, the UE requires that the redirection strategy be used for frequency layer convergence. 4. HO_ALGO_OVERLAY_SWITCH: When the switch is on, the associated receiving and mobility algorithms of the overlay network are used. When the switch is not on, the associated algorithms are not used. Overlay network is an UTRAN network covering present network, it supports HSPA, MBMS and other new features. To satisfy new requirements of operator and restrictions of present network, overlay network realizes operation distribution and load sharing between new network and present network, also gives special handling for mobility management of network verge. 5. HO_INTER_FREQ_HARD_HO_SWITCH: When the switch is on, the RNC is allowed to initiate inter-frequency measure control or the load-based inter-frequency hard handover upon the handover decision on inter-frequency load. 6. HO_LTE_SERVICE_PSHO_OUT_SWITCH: Whether to enable service-based PS handover from UMTS to LTE. When this switch is turned on, the RNC can send LTE MEASUREMENT CONTROL message based on service and initiate service-based PS handover from UMTS to LTE. When this switch is turned off, the RNC cannot initiate service-based PS handover from UMTS to LTE. 7. HO_INTER_RAT_CS_OUT_SWITCH: When the switch is on, the RNC is allowed to initiate inter-frequency measure control and the CS inter-RAT hard handover from the 3G network to the 2G network. 8. HO_INTER_RAT_PS_3G2G_CELLCHG_NACC_SWITCH: When the switch is on, the NACC function is supported during the PS inter-RAT handover from the 3G network to the 2G network in the cell change order process. When the switch is not on, the NACC function is not supported. When PS_3G2G_RELOCATION_SWITCH is ON, this switch is useless. When the NACC function is supported, the UE skips the reading procedure as the SI/PSI of the target cell is provided after the UE accesses the 2G cell. Thus, the delay of inter-cell handover is reduced. 9. HO_INTER_RAT_PS_3G2G_RELOCATION_SWITCH: When the switch is on, the PS inter-RAT handover from the 3G network to the 2G network is performed in the relocation process. When the switch is not on, the PS inter-RAT handover from the 3G network to the 2G network is performed in the cell change order process. 10. HO_INTER_RAT_PS_OUT_SWITCH: When the switch is on, the RNC is allowed to initiate inter-frequency measure control and the PS inter-RAT hard handover from the 3G network to the 2G network. 11. HO_INTER_RAT_RNC_SERVICE_HO_SWITCH: When the switch is on, the attributes of inter-RAT handover of the services are based on the configuration of RNC parameters. When the switch is not on, the attributes are set on the basis of the CN. If no information is provided by the CN, the attributes are then based on the RNC parameters. 12. HO_INTRA_FREQ_DETSET_INTO_ACTSET_SWITCH: When the switch is on, the cells in the detected set from which the RNC receives their valid event reports can be added to the active set. The cells allowed to be added to the active set must be the neighboring cells of the cells in the active set. 13. HO_INTRA_FREQ_DETSET_RPRT_SWITCH: When the switch is on, the intra-frequency measurement reports of the detected set can be reported by UE. 14. HO_INTRA_FREQ_HARD_HO_SWITCH: When the switch is on, the RNC is allowed to initiate the intra-frequency hard handover. 15. HO_INTRA_FREQ_RPRT_1J_SWITCH: When the switch is on, the event 1J is included in the delivery of intra-frequency measurement control if the UE version is R6. 16. HO_INTRA_FREQ_SOFT_HO_SWITCH: When the switch is on, the cells on the RNC can active the soft handover. When the RNC receives reports on the events 1A, 1B, 1C, or 1D, associated addition, removal, and replacement of handover cell of the soft handover are initiated. 17. HO_MC_MEAS_BEYOND_UE_CAP_SWITCH: When the switch is on, the neighboring cell whose frequency band is beyond the UE's capabilities can also be delivered in the inter-frequency measurement list. 18. HO_MC_NCELL_COMBINE_SWITCH: When the switch is on, the neighboring cell combined algorithm is used during the delivery of the objects to be measured. When the switch is not on, the optimal cell algorithm is used. 19. HO_MC_SIGNAL_IUR_INTRA_SWITCH: When the switch is on, intra-frequency handover is allowed over the Iur interface if the UE has only signaling. 20. HO_MC_SIGNAL_SWITCH: When the switch is on, quality measurement on the active set is delivered after signaling setup but before service setup. If the UE is at the cell verge or receives weak signals after accessing the network, the RNC can trigger inter-frequency or inter-RAT handover when the UE sets up the RRC. 21. HO_MC_SNA_RESTRICTION_SWITCH: When the switch is on, the RNC controls the UEs in the connected state based on the configurations on the CN. The UEs can only access and move in authorized cells. 22. HO_LTE_PS_OUT_SWITCH: Whether to enable handover from UMTS to LTE. When this switch is turned on, the RNC can send LTE MEASUREMENT CONTROL message and initiate PS handover or redirection from UMTS to LTE. When this switch is turned off, the RNC cannot perform the preceding procedures. 23. HO_LTE_SERVICE_PS_OUT_SWITCH: Whether to enable service-based redirection from UMTS to LTE. When this switch is turned on, the RNC can send LTE MEASUREMENT CONTROL message based on service and initiate service-based PS redirection from UMTS to LTE. When this switch is turned off, the RNC cannot initiate service-based PS redirection from UMTS to LTE. 24. HO_H2G_SRVCC_SWITCH :This bit is a Single Radio Voice Call Continuity (SRVCC) switch for the VoIP service that is handed over to GERAN. SRVCC ensures the continuity of voice services that are handed over between the CS domain and the IP Multimedia Subsystem (IMS).The meaning of the bit is as follows: When it is set to "ON", it indicates that the VoIP service can be handed over to GERAN through SRVCC procedure.When it is set to "OFF", it indicates that the VoIP service cannot be handed over to GERAN through SRVCC procedure. 25. HO_INTRA_FREQ_HIGHPRIOR_2D2F_SWITCH: This switch controls which event to be preferentially processed when both an intra- frequency measurement report event and event 2D or 2F need to be processed. Turning on this switch allows the intra-frequency measurement report event to be preferentially processed. Turning off this switch allows event 2D or 2F to be preferentially processed. 26. HO_CIO_1D_USED: Whether the RNC instructs the UE to use the cell individual offset (CIO) parameter when reporting event 1D. If this field is selected, the RNC instructs the UE to use the CIO parameter when reporting event 1D. If this field is not selected, the RNC does not instruct the UE to use the CIO parameter when reporting event 1D. The call drop rate will increase if the switch is opened when the CIO is configured to a big value. 27. HO_HCS_SPD_INI_BSD_UE_SWITCH: Whether the RNC determines the initial speed state of a UE based on the enUeMobilityStateInd information element (IE) sent by the UE. If this switch is turned on, the initial UE speed state is determined by this IE carried in the RRC_RRC_CONNECT_REQ or RRC_CELL_UPDATE message. If this switch is turned off, the RNC determines the UE mobility state as before based on how frequently the UE sends an event 1D measurement report. 28. HO_L2U_EMGCALL_SWITCH: Whether to activate CS Fall Back. When this switch is turned on, CS Fall Back is activated. When this switch is turned off, CS Fall Back is deactivated. 29. HO_UMTS_TO_LTE_FAST_RETURN_SWITCH: Switch for preferentially moving to an LTE cell after a call release. When this switch is turned on, the RNC includes the neighboring frequency information in the RRC CONNECTION RELEASE message for UEs that can measure signal quality of the frequency band including the LTE cells' frequencies. As a result of these operations, these UEs can preferentially move to LTE cells after entering the idle state. 30. HO_HHO_WITH_INTRA_FREQ_MR_SWITCH: When this switch is turned on, the RNC sends periodical inter-frequency and intra-frequency measurement control messages, and includes the information element (IE) measurementIdentiy in the inter-frequency measurement control message to instruct a UE to report signal quality in an active set cell in a periodical inter-frequency measurement report. When this switch is turned off, the RNC sends only a periodical inter-frequency measurement control message without this IE. 31. HO_MULTIRAB_CSPS_HO_COV_PARA_SWITCH (Algorithm Switch for Coverage-based Inter-frequency or inter-RAT Handover Parameters Dedicated to CS and PS Combined Services): When this switch is turned on, the handover parameters dedicated to CS and PS combined services are used when CS and PS combined services are processed. When this switch is turned off, the thresholds for CS or PS services, whichever are larger, are used for the handover parameters.
