[PS Documentation] EPC Signaling and Protocol Analysis

1. Application Description

1) Service Description

To facilitate fault locating and deepen understanding of services, network maintenance engineers need to know common standard protocols and signaling flows of typical services on EPC networks.

2) Documentation Description

The EPC Signaling and Protocol Analysis provides signaling flows of typical services. Performance counters, message body, and information elements (IEs) involved in every signaling flow are described.

2. Highlights

The EPC Signaling and Protocol Analysis is provided in UGW9811V900R009C01 and later versions and has the following highlights:

l Provides end-to-end message flows and measurement points of key performance indicators (KPIs) between the MME, S-GW, and P-GW on an EPC network.

l Combines message flows with KPIs to facilitate problem analysis.

l Combines messages, IEs, and error codes to facilitate problem troubleshooting.

[PS Documentation] Error Codes

1. Application Description

1) Service Description

If interworking between NEs is faulty, you can locate the fault according to the error codes contained in the returned message. To facilitate locating faults in interworking between NEs, Error Code Guide provides common error codes over interfaces that network maintenance engineers need to know.

2) Documentation Description

The Error Code node provides guides for troubleshooting error codes over interfaces, such as the Gn, S4/S11/S5/S8/S2a/S2b, and Gy interfaces.

2. Highlights

The Error Code Guide is provided in UGW9811V900R009C01 and later versions and has the following highlights:

l Provides guides for troubleshooting error codes over interfaces, such as the Gn, S4/S11/-S5/S8/S2a/S2b, and Gy interfaces to facilitate signaling fault locating.

l Provides commands, alarms and related hyperlinks.

l Provides key parameters to be observed and fault locating criteria.

l Provides performance counters affected by error codes in reference information.
