The Database definitions used in the BBN installation can found it this SQL dump file [https://raw.githubusercontent.com/GENI-NSF/geni-support/master/wireless/oai_db.sql oai_db.sql]. The BBN installation used the existing Access Point Name (APN) "orbitA" which was entered in the Packet Data Network (PDN) table definitions. 408 409 Following are OAI DB rule which must be met: 406 The OAI uses a database to store setting in the following 6 tables: apn, mmeidentity, pdn, pgw and users. The Database definitions initially used in the BBN installation can found it this SQL dump file [https://raw.githubusercontent.com/GENI-NSF/geni-support/master/wireless/oai_db.sql oai_db.sql]. The BBN installation used the existing Access Point Name (APN) "orbitA" which was entered in the Packet Data Network (PDN) table definitions. Modifications were made to the OAI DB to add Rutgers Devices. A SQL dump of the BBN OAI database including the Rutgers devices can be seen in the [https://raw.githubusercontent.com/GENI-NSF/geni-support/master/wireless/oai_db-rutgers-devices.sql oai_db-rutgers-devices.sql] file. 407 408 A ruby script [https://raw.githubusercontent.com/GENI-NSF/geni-support/master/wireless/fill_sql.rb fill_sql.rb ] was provided by Rutgers to make database changes for adding the mmeidentity entry for the user and pdn tables. Modifications were made to set the BBN realm, mme and hss values in the script: 409 {{{ 410 < realm = '.donotdelete.ch-geni-net.instageni.gpolab.bbn.com' 411 < mme = 'gpo-pc.donotdelete.ch-geni-net.instageni.gpolab.bbn.com' 412 < hss = 'hss.donotdelete.ch-geni-net.instageni.gpolab.bbn.com' 413 }}} 414 415 The [https://raw.githubusercontent.com/GENI-NSF/geni-support/master/wireless/fill_sql-bbn.rb fill_sql-bbn.rb] ruby script was used to initialize the ''mmeidentity'' in the BBN OAI DB. 416 417 In defining the OAI database at BBN, some DB rule were discovered that must be met: 410 418 411 419 1. The "pdn" Table "PGW_id" entry must be a unique "id" that must match the "id" value in the "pgw" table: … … 459 467 460 468 461 The "BBN_band-41" Cell Radio Profile was created for our setup. Each site must create its own Cell Ratio Profile and requires that you first know the EUTRA Absolute radio-frequency channel number (EARFCN) assignment for your site. The [http://wimax.orbit-lab.org/wiki/aaOperations#OperationsObjectives Orbit-Lab Site Operation Resources] page provides a table of Sites with '''Lower Frequency (MHz)''' and '''Upper Frequency (MHz)''' allocated for that sites in the GENI LTE effort. The BBN Base Station configured in this example has the Lower Frequency 2573 MHz and the Upper Frequency 2583 MHz, a 10 MHz range. To calculate the EARFCN for the BBN Cell Radio Profile a [http://niviuk.free.fr/lte_band.php LTE Frequency Calculator] was used and the '''Center Frequency''' 2578 MHz was entered in the [http://niviuk.free.fr/lte_band.php LTE Frequency Calculator] to determine the '''Band Value''' and '''EARFCN DL''' values to be used in our Radio Cell Profile: 469 The "BBN_band-41" Cell Radio Profile was created for our setup.
