The WDS Globalmine API is a public facing API proxy for accessing all of the WDS capabilities.

The WDS Enterprise Messaging Gateway (EMG) module is a messaging gateway / router that is responsible for the routing & queuing of SMPP & HTTP traffic between WDS services.  For example,  EMG can send an SMS asking if the subscriber wants settings to be sent,  and then when the subscriber responds with a ‘Y’ or ‘Yes’,  EMG will send an HTTP request to the WDS Advanced Device Management (ADM) module to trigger the configuration.

The Type Allocation Code (TAC) is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices. TAC numbers can be used to identify devices connected to networks and act as a unique identifier to link our capabilities together.

The GSM Association is an industry organisation that represents the interests of mobile network operators worldwide. They are the global administrator of Type Allocation Code (TAC), which forms part of the IMEI (International Mobile Station Equipment Identity) number and is used to identify a device on the network.

The WDS Advanced Device Management (ADM) module is responsible for determining the correct settings based upon the device type & capabilities to be configured, building the settings profile, and then sending via the WDS Enterprise Messaging Gateway (EMG).

The WDS Auxiliary Data Connector (ADC) module is an integration & orchestration layer which is responsible for updating downstream systems with real time subscriber data and creating a session within which subscribers can interact with the overall platform to request settings via SMS. ADC also exposes APIs that allows customers to look up subscriber/device information,  and trigger device configuration.

Device Management is a term used to describe any process that helps to manage a device on an operator’s network. It may include identifying the device, validating and updating the settings on the device, or triggering a Firmware update to ensure the device is running the latest version of its firmware.

The Open Mobile Alliance (OMA) is a standards organization which develops international standards for the mobile/cellular phone industry.  It is now known as OMA SpecWorks.

OMA DM is a protocol specified by the OMA for managing certain processes like Firmware updates and querying the status of a device. It is effectively a dialog between a device and a remote server where information can be exchanged and acted on accordingly. It allows operators to communicate with the device and perform processes often in the background and with little user interaction. WDS have been testing devices via OMA DM for more than 10 years – get in touch if you have any questions on how we can help.

OMA CP is a protocol specified by the OMA for updating or installing various settings onto a mobile/cellular device which then allow that device to function correctly, for example connecting to the internet. OMA CP messages are typically sent to a device via an SMS message and require the user to open the message and save the setting onto the device. Unlike OMA DM, there is no dialog between the device and the originating server, so it is difficult to know whether a message has been received, opened or successfully saved. WDS have been providing an OMA CP solution since the late 1990s and continue to add support for 100’s of devices every month. Get in touch if you have any questions.

An eSIM is a SIM that is embedded onto part of the circuitry in a device. It replaces the need to insert a physical SIM and so is smaller and potentially more convenient for the user. As it is embedded, it does need to be provisioned with the correct settings in order for the device to work correctly and this does provide the potential for problems to occur. Get in touch to find out how WDS can help mitigate eSIM configuration problems and improve the user experience when changing operator via eSIM.

iSIM stands for integrated SIM. It means the SIM function is integrated into an existing chip on the device and saves even more space than eSIM. This is a new technology and is something we will be watching closely to see how it develops!
