One of many key advantages of utilizing an eSIM (embedded SIM) over the standard SIM is distant provisioning.
Whereas in conventional SIM playing cards we're required to bodily change the SIM card after we need to transfer between completely different community operators. Nevertheless, an eSIM can obtain and retailer a number of SIM recordsdata from a number of completely different networks, and so you may simply swap between networks from the community supplier’s app or by scanning a QR code. That is referred to as distant SIM provisioning (RSP).
An entitlement server, nevertheless, additional enhances RSP by permitting the obtain of SIM knowledge into the eSIM with out utilizing QR codes, simplifying the method for subscribers. The entitlement servers primarily allow the operator to tell gadgets of which companies are presently out there to make use of on their community, in addition to implementing which subscribers can entry these companies.
Right here we are going to talk about all you'll want to know in regards to the eSIM entitlement server, its use case, and its advantages to your connectivity.

What Is an Entitlement Server?
An entitlement server, or to be extra correct a Machine Entitlement Server (DES), is a cell that allows machine entitlement.
Machine entitlement, or simply entitlement, is a cell community performance that enables the cell community to tell a cell machine about which companies can be found to make use of on the community, and likewise to validate which subscribers can entry which companies.
Entitlement server is essential as a result of till just lately, gadgets can't obtain machine configuration functionalities of IMS (IP Multimedia Providers) requirements by way of OTA (over-the-air) obtain based on the. Thus, gadgets (smartphones) can't use IMS companies offered by the operators, together with however not restricted to VoLTE (Voice over LTE) and ViLTE (Video over LTE).
An entitlement server primarily solves this drawback by introducing a tool and subscriber authentication performance and an OTA configuration functionality.
The function of entitlement servers
An entitlement server’s essential function is to validate whether or not the community helps the superior community options required by the machine and whether or not the subscriber is permitted to entry these options.
The second function, as soon as the validation is full, is to facilitate the mandatory steps to provision the options on each the community and the machine.
Entitlement servers are utilized through the machine onboarding course of, and so sometimes the entitlement servers will combine a small internet web page or internet API to show and/or accumulate info from the subscriber. This info can embody present subscription standing, amassing cost info, asking consent to phrases and situations, so on.
The aim of utilizing this internet web page is to permit a smoother machine onboarding course of as facilitated by the entitlement server, to make sure a seamless person expertise.
Widespread Use Instances for Entitlement Servers
Why are entitlement servers necessary for each person expertise and community efficiency? Under we are going to talk about a number of the commonest use circumstances of entitlement servers and their advantages.
OTA service updates on smartphones
An entitlement server can be utilized for pushing service (software program) updates on smartphones. On iPhones, for instance, the entitlement server can push a service configuration replace for the VoLTE service by way of Apple Push Notification Service. This fashion, when there may be an out there replace to the VoLTE service, the entitlement server will push a notification to the iPhone.
The machine will then reply to the entitlement server to get the service configuration replace, and in return, the entitlement server will validate the machine’s subscription. When all the things is deemed legitimate, the entitlement server will ship the replace.
Automated configuration of superior companies on smartphones
Entitlement servers can mechanically configure Android and iPhone smartphones with the suitable settings for the superior companies. For instance, configurations for Voice over Wi-Fi and Wealthy Communication Service (RCS). If vital, configuration particulars might be deployed on a daily interval to make sure up-to-date configurations on all smartphones linked to the operator’s community.
Automated configuration for Android telephones
Android telephones can obtain automated configuration primarily based on the GSMA RCC.14 and RCC.15 requirements, though not all Android telephones assist these customary specs in the meanwhile.
For Android telephones that do assist RCC.14 and 15, the cellphone can mechanically register itself on the IMS community and hook up with the entitlement server. The entitlement server will then validate the subscriber’s id and can present the machine with up-to-date configurations.
Configuration on wearable gadgets
The entitlement server can also be essential in enabling wearable gadgets like Apple Watch or Samsung Galaxy Watch to obtain configurations and updates over the air. For Apple Watches, the subscriber can simply pair the Apple Watch with the iPhone (by way of Bluetooth), and the iPhone will mechanically provoke a Watch provisioning by way of an entitlement server.
As soon as the entitlement server has validated that the Apple Watch is certainly allowed to make use of IMS companies, the subscriber may be requested to offer further info by way of web-based APIs. The entitlement server will then ship an up to date eSIM profile to the wearable, and the subscriber can start utilizing the companies instantly.
Closing Ideas
Truphone Entitlement Resolution is superior performance that enables operators to mechanically provision and configure gadgets together with wearables like Apple Watch and Samsung Galaxy Watch. Whereas up to now enabling an entitlement server required a fancy integration between the machine and the community (which might be costly for the community), Truphone entitlement gives an economical resolution.
With Truphone entitlement, you don’t want overly advanced APIs, however as a substitute, you’ll get easy web-based APIs that work on any machine and working system. You’ll get an economical resolution that can also be to implement to deploy a completely strong, multi-site, in-network entitlement server resolution.
