1. Introduction1.1. PurposeThis document lists all RAN parameters for Ericsson P5 release along with their recommended values.

1.2. DetailsThis parameter list only contains recommendations for RAN parameters.The sheet "Exportable Parameters" refers to parameters that can be exported from the OSS.The sheet "Unexportable Parameters" refers to all other RAN parameters.The values for parameters related to features not currently deployed (like HSUPA) are shown as N/A. Also parameters that don't have the same value for all cells are also shown as N/A.For questions on this document contactSireesha [email protected] 383 2716

Altitudes larger than 32767 meters are represented as 32767 meters.

Before starting the GPS measurements in the UE, the RNC makes a pre-estimate of the UE position. If the pre-estimate is successful, it is used as the UE reference position. If the pre-estimate fails, a fall-back position is used as the UE reference position instead. This reference position is sent from the RNC to the UE when starting the GPS measurements.

Part of the Downlink Offset (DO).

Represents the maximum transport delay between the RNC and the RBS, including transport network associated delays in each node. Used as a compensation to secure that a traffic frame will have a guaranteed time margin at reception in the RBS (before the ToAWE point).

The DTO shall take delay variations into account, assuming a very low probability that the real transport delay exceed the DTO. Note that the same value shall consider the possible intra-RNS as well as inter-RNS transport connections.

If this value is set too low, frames may be lost/discarded (due to too-late arrival). As a secondary result, the RBS may issue Timing Adjustment control frames toward the RNC (due to out-of-window detection).

Actual setting can deviate from the default setting to limit the number of simultaneous number of multi RAB connections in the RBS, typically to deal with limitations in the Transport Network.
