| 发明名称 | Subscriber-specific tracing in communications | ||
| 摘要 | A method for subscriber tracing comprises capturing user plane packets in a network apparatus implementing a 3GPP policy and charging enforcement functionality PCEF. Packet-specific metadata is added to a captured user plane packet. The packet-specific metadata may be used for facilitating subscriber-specific troubleshooting of core network elements. | ||

| 主权项 | 1. A method for subscriber tracing in a communications system, said method comprising: capturing, in a network apparatus, user plane packets, wherein the apparatus implements a 3GPP policy and charging enforcement functionality PCEF; and adding packet-specific metadata to a captured user plane packet, wherein the packet-specific metadata is used for facilitating subscriber-specific troubleshooting of core network elements, and wherein the metadata includes a public part documented in product-specific customer documentation, and/ora private part intended for troubleshooting by the product vendor, and including information on an exact code point, licensing information, internal resource situation information, and/or other private information. | ||
