Section: 9.11.4.24 IP header compression configuration
Content: The purpose of the IP header compression configuration information element is to negotiate ROHC channel setup parameters specified in IETF RFC 5795 [39B] and, optionally, provide additional header compression context setup parameters. The IP header compression configuration information element is coded as shown in figure 9.11.4.24.1 and table 9.11.4.24.1. The IP header compression configuration is a type 4 information element with a minimum length of 5 octets and a maximum length of 257 octets. The optional Additional IP header compression parameters container field conveys the additional header compression context setup parameters as specified in 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [8] in a generic container. This field corresponds to the profile-specific information in the header of the ROHC IR packet type in IETF RFC 5795 [39B].
