    1 Introduction to CHR Standard Signalling Northbound Data Export

    About This Chapter

    With mobile operators embarking on building their own radio network optimization platform,

    it is required that equipment manufacturers provide the call history record (CHR) data for

    network analysis.

    The Nastar provides the northbound CHR data (created during one call) of RAN13 and earlier

    versions. As the northbound CHR data depends on NE logs, it has the following

    shortcomings:

    Multiple radio access bearers (RABs) are not supported. Multiple RABs is common for

    the smart terminal.

    The switch information is incomplete. Only two switches are recorded during one call.

    The data timeliness is poor. Data is recorded and reported only after a call ends.

    Data is not standard. The data is recorded in the NE proprietary log. The extracted

    information element (IE) content and recording format vary according to the NE version.

    Due to the preceding problems, the original northbound CHR data cannot meet the customer's

    requirement for network analysis. Therefore, the CHR content and format are redesigned in

    RAN14 or later.

    For the Huawei RAN14, the Nastar takes the CHR open standard signaling as the northbound

    data source and provides rich standard message types to meet the customization requirement

    of operators. In addition, the Nastar will provide more standard, efficient, and dependable

    interfaces with better compatibility.

    1.1 Nastar Networking Architecture

    This section describes the Nastar networking architecture and CHR Standard Signalling

    Northbound Data sources on the network.

    1.2 Working Principles of Data Export

    This section describes the working principles for the Nastar system to export CHR Standard

    Signalling Northbound Data in the direct and relay-based networking schemes.
