Comment

To request to configure PDCP entity. Setup is used for creation of the PDCP instances or the PDCP resources. Release is used for free the all PDCP resources. The reconfiguration is to change the PDCP parameters. PDCP entity does not belong to a particular cell, the cellId shall assign the value -1. the routingInfo is RB identity which is used to connect this PDCP entity to the RLC entity with the same RB identity and it is also used for PDCP_DATA_REQ ASP to transmit data through this PDCP entity.

Comment

To request to reinitialize/context-relocate the compression protocol. PDCP entity does not belong to a particular cell; the cellId shall assign the value -1. The routingInfo is RB identity which is used to connect this PDCP entity to the RLC entity with the same RB identity and it is also used for PDCP_DATA_REQ ASP to transmit data through this PDCP entity.

For reinitialization:

– Configured compression parameters remain valid.

– All compression state information is initialized.

– The PDCP sequence numbers are not changed.

– Actions specified in section 6.3.1 of RFC 3095 [54].

For contextRelocation:

– initialize the context with the parameter in the ASP

– valid for RFC3095 compression only
