An introduction to YateMMI
YateMMI purpose is that of allowing an easy configuration of all the Yate-based products.
Software wizards (also known as setup assistants) will lead the user through a series of well-defined steps to set up MMI access, Network settings, Subscribers and Equipments.
The configuration procedures are easy, without an excess of technical information. YateMMI does not demand special training or a dedicated network administrator to handle the overall configuration (especially not for the standard settings).
YateMMI is installed on the first product you purchased or can be installed on a separate equipment, and can be accessed remotely from any part of the world. It uses the JSON API of each equipment.
The MMI was created with the purpose of aiding operators in typical configuration scenarios. For more special configuration scenarios, a dedicated extension will be provided.
YateMMI allows to set generic information about the network, the roaming partners settings, the interconnect settings, the equipment settings, as well as the subscriber management for YateHSS/HLR.
Configurations are done though wizards (more details here).
Types of equipment
Our main core network equipments are:
- YateUCN, a unified core network solution that implements the functions below in software, in a single, commodity hardware server:
- all the functions and protocols of the LTE EPC (MME, S-GW, P-GW, PCRF, and PCEF)
- all the functions and protocols of the LTE VoLTE IMS P-CSCF, I/S-CSCF, IWF, and BGW
- all the functions and protocols of the GSM/GPRS core network (MSC/VLR/SGSN/GGSN/GMSC)
- YateHSS/HLR, the subscriber server for GSM, UMTS, LTE, IMS, Wi-Fi networks, using both Diameter and SS7 MAP for authentication
- YateSMSC, a SMS Center that fulfills all the functions of a conventional SMSC: forwarding, storing and delivering SMSs in GSM, UMTS and LTE networks.
- YateSTP, a Signal Transfer Point (STP) who acts as a router that relays SS7 messages between signaling end-points (SEPs) and other signaling transfer points (STPs).
- YateDRA, a Diameter Routing Agent (DRA) capable of routing requests based on configurable rules.
Management of Radio Access Network equipments via MMI is not yet supported.
Our main RAN equipments are:
- SatSite Model 142, a complete 4G LTE eNodeB, containing both the radio and baseband functions.
It can also be configured via software to operate as a 2.5G GSM/GPRS BTS+BSC.
For configuring and managing the SatSite via YateMMI, refer to the following pages:
- [link SatSite YateMMI LTE Configuration]
- [link SatSite YateMMI GSM Configuration]
- LabKit, a 2.5G GSM/GPRS network in a single box which can be upgraded to a complete 4G LTE network.
- [link LTE Labkit YateMMI LTE Configuration]
- [link LabKit YateMMI GSM Configuration]
YateMMI is organized in various contexts:
- My Network
- Subscriber Management
Each context has multiple modules and each of these modules can be either enabled or disabled.
Contexts use wizards for a well-defined step-by-step configuration.
To find out more about each wizard's field, read the explanations marked with the ? (question mark).
There are different wizards for each equipment type:
- a wizard for YateHSS/HLR and YateUCN
- a different wizard for base stations
Each wizard was designed with the purpose of generating all the necessary SS7, Diameter and equipment-specific settings.
After setting up the equipment the administrator has to confirm if he wants to apply changes: "You have changes to apply. [Apply] [Review] [Drop changes]."
A second notice "You have changes and they were marked to apply." will appear and a cron (a time-based job scheduler) will apply the settings to the equipment.
The administrator will be notified if the configuration was successful or not.
Note: Some users have 'Allow web apply' activated. On these users, cron can be bypassed with [Push settings now] button that appears with second notice.
This context allows the administrator to set general information about the network. All this information is necessary for the equipment he will later on add.
The administrator can start adding only one equipment, and later add more. In case he wants to configure multiple equipment, YateMMI will generate pools of IP addresses, point codes, global titles and more.
Pools are an essential concept used for setting up the network.
To setup more pieces of equipment of the same type, an administrator may use:
- Pools of Global Titles that will be automatically associated to the network nodes if 'Automatically associate GT to equipment' is enabled.
- Pools of Pointcodes that will be automatically associated to the network nodes if 'Automatically associate PC to equipment' is enabled.
- Pools of IP addresses that will be automatically associated to equipment if 'Automatically associate IP to equipment' is enabled.
The administrator has to define the pools depending on their purpose, be it Radio Network equipment, Core Network, other networks, management or SatSite.
An equipment uses multiple addresses depending on the equipment type.
Each YateUCN has a pool of IPs associated to each GTP-U tunnel.
If the 'Automatically associate pools to YateUCN' option is enabled then this pools are associated automatically to YateUCN.
The My Network context has various modules, as seen below.
Currently, the Network Settings tab has two setup types:
- Just YateHSS/HLR - especially designed for MVNOs and allows adding and configuring only a YateHSS/HLR.
- Extending network - designed to allow adding all Core equipments to a new or an existing network.
The BTS Templates included Rural and Urban templates for adding basestations and eNodeBs. Each template has a number of configuration settings tabs. ==== Interconnect ==== -->
- Profiles module - allows configuring SIM profiles, as well as CS, PS, IMS, EPC profiles for the subscribers' network services.
- Subscribers - allows SIMs import based on a SIM profile, and subscribers management (add/edit/delete)
Note: The OSS/BSS services are not included in YateMMI, however it allows applying development APIs for OSS/BSS integration.
