Detailed Interface¶

Events¶

gtpv1_create_pdp_ctx_request¶

Type: event (c: connection, hdr: gtpv1_hdr, elements: gtp_create_pdp_ctx_request_elements)

Generated for GTPv1-C Create PDP Context Request messages.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.
elements – The set of Information Elements comprising the message.

gtpv1_create_pdp_ctx_response¶

Type: event (c: connection, hdr: gtpv1_hdr, elements: gtp_create_pdp_ctx_response_elements)

Generated for GTPv1-C Create PDP Context Response messages.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.
elements – The set of Information Elements comprising the message.

gtpv1_delete_pdp_ctx_request¶

Type: event (c: connection, hdr: gtpv1_hdr, elements: gtp_delete_pdp_ctx_request_elements)

Generated for GTPv1-C Delete PDP Context Request messages.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.
elements – The set of Information Elements comprising the message.

gtpv1_delete_pdp_ctx_response¶

Type: event (c: connection, hdr: gtpv1_hdr, elements: gtp_delete_pdp_ctx_response_elements)

Generated for GTPv1-C Delete PDP Context Response messages.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.
elements – The set of Information Elements comprising the message.

gtpv1_g_pdu_packet¶

Type: event (outer: connection, inner_gtp: gtpv1_hdr, inner_ip: pkt_hdr)

Generated for GTPv1 G-PDU packets. That is, packets with a UDP payload that includes a GTP header followed by an IPv4 or IPv6 packet.

Parameters

outer – The GTP outer tunnel connection.
inner_gtp – The GTP header.
inner_ip – The inner IP and transport layer packet headers.

Note

Since this event may be raised on a per-packet basis, handling it may become particularly expensive for real-time analysis.

gtpv1_message¶

Type: event (c: connection, hdr: gtpv1_hdr)

Generated for any GTP message with a GTPv1 header.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.

gtpv1_update_pdp_ctx_request¶

Type: event (c: connection, hdr: gtpv1_hdr, elements: gtp_update_pdp_ctx_request_elements)

Generated for GTPv1-C Update PDP Context Request messages.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.
elements – The set of Information Elements comprising the message.

gtpv1_update_pdp_ctx_response¶

Type: event (c: connection, hdr: gtpv1_hdr, elements: gtp_update_pdp_ctx_response_elements)

Generated for GTPv1-C Update PDP Context Response messages.

Parameters

c – The connection over which the message is sent.
hdr – The GTPv1 header.
elements – The set of Information Elements comprising the message.
