  1. Network Entry

  2. System Activation • System activation requires the execution of the following steps: • Commissioning • Base Station radio parameters configuration • SU radio parameters configuration • Network Entry • SU registration with the Base Station • Services provisioning • Defining users operation terms • Allowing users operation, based on predefined service terms

  3. Network Entry Definition • Network entry is the process of Subscriber Unit registration with the respective base station: • AU registers with NPU - after AU Power-On • SU registers with NPU (Via AU) or µBST - after SU commissioning (radio link activation)

  4. Network Entry AU Registration NPU AU SU • AU power up (1) • Keep Alive Process – The AU sends "keep alive" messages to the NPU (every 2 seconds) and vice versa. If the NPU is not receives a "keep alive" message within 30 seconds, it resets the AU (2 and 3) • DHCP Process – The AU requests an IP address according to the DHCP protocol (DHCP Request), the NPU respond to the AU with aDHCP Response message containing the following parameters: • IP Address – an internal IP address of the AU (1.AU-ID.0.1 where AU-ID=AU slot number in the shelf) • Syslog server address – saves the AU messages • TFTP server address – for software download • Time server address – synchronizes the AU with the NPU time All three addresses (Syslog, TFTP and Time servers) are the NPUIP address (4 and 5) • Software download process – the NPU checks the version of the AU. If the version is older than configured, a software download session starts. At the end of the process, the NPU sends a Reset andRun from Shadow command to the AU (6 through 9) • The AU resets and runs from shadow (10) 1 Keep Alive 2 Keep Alive 3 DHCP Req 4 DHCP Res 5 Get Version 6 Version Res 7 Version Name 8 TFTP Session 9 9 10

  5. Network Entry AU Registration NPU AU SU • The NPU sends Make Operational command to the AU (the shadow version will be marked as operational and vice versa) (11) • Configuration download – the NPU downloads the configuration tothe AU. The AU must be reset after the configuration download (12) • The AU transmits uplink and downlink maps (13) 1 Keep Alive 2 Keep Alive 3 DHCP Req 4 DHCP Res 5 Get Version 6 Version Res 7 Version Name 8 TFTP Session 9 9 10 Make Oper 11 Config. Down. 12 UL+DL Maps 13

  6. Network Entry SU Registration NPU AU SU • SU Commissioning (14) • Synchronization phase (15 through 17) • The SU waits to receive at least four consecutive mapstransmitted by the AU • The SU checks that the AU matches the BST-ID and the mask • The SU waits to receive also the Uplink Channel Descriptor (UCD) • Initial Ranging phase (18 through 19) • The AU broadcasts Initial Management information within theUplink map • The SU transmits ranging packet (RNG_REQ) to the AU • The AU allocates a management connection for the SU andnotifies the SU about the connection ID (RNG_RSP) • Authentication (20 through 21) • The SU delivers the certificate (X.509) in order to authenticatewith the NPU. The certificate is encrypted (AUTH_REQ) • The NPU decrypts the certificate and verifies the integrity of the certificate fields (AUTH_RSP) • In case a RADIUS server option is used the authentication isperformed using the RADIUS server (more details provided at theservices presentation) 1 Keep Alive 2 Keep Alive 3 DHCP Req 4 DHCP Res 5 Get Version 6 Version Res 7 Version Name 8 TFTP Session 9 9 10 Make Oper 11 Config.

  7. Network Entry SU Registration NPU AU SU • Registration (22 through 23) • The SU delivers a Registration Request to the NPU via the AU • If the configuration allows it, a Registration Response is delivered from the NPU to the SU via the AU • DHCP Process – The SU requests an IP address according to the DHCP protocol (DHCP Request to the NPU, via the AU, the NPU respond to the SU, via the AU, with a DHCP Response message containing the following parameters: • IP Address – an internal IP address of the SU (1.AU-ID.SU-ID+1 where SU-ID is two bytes long and is equal to the numberof SUs in the AU association table) • Syslog server address – saves the SU messages • TFTP server address – for software download • Time server address – synchronizes the SU with the NPU time All three addresses (Syslog, TFTP and Time servers) are the NPUIP address (24 through 25) AUTH_REQ 20 AUTH_RSP 21 Registration Request 22 Registration Response 23 DHCP Request 24 DHCP Response 25

  8. Network Entry SU Registration NPU AU SU • Firmware Download (26 to 28) for Temporary SUs in Quick mode • The NPU polls the SU, via the AU, for its versions • The SU sends to the NPU, via the AU, its versions identifier (numbers) • The NPU checks within the configuration if the SU is running with the correct version. If the SU is not running with the correct version, the NPU will download to the SU the correct firmware, if needed • Configuration download – the NPU opens a TFTP session to download the configuration to the SU via the AU (29) AUTH_REQ 20 AUTH_RSP 21 Registration Request 22 Registration Response 23 DHCP Request 24 DHCP Response 25 Firmware Version Request 26 Firmware Version Response 27 Firmware Download 28 Configuration Download 29
