Ericsson Technology Review: Service exposure: a critical capability in a 5G world

269 visualizações

Publicada em

To meet the requirements of use cases in areas such as the Internet of Things, AR/VR, Industry 4.0 and the automotive sector, operators need to be able to provide computing resources across the whole telco domain – all the way to the edge of the mobile network. Service exposure and APIs will play a key role in creating solutions that are both effective and cost efficient.

The latest Ericsson Technology Review article explores recent advances in the service exposure area that have resulted from the move toward 5G and the adoption of cloud-native principles, as well as the combination of Service-based Architecture, microservices and container technologies. It includes examples that illustrate how service exposure can be deployed in a multitude of locations, each with a different set of requirements that drive modularity and configurability needs.

JAN FRIMAN, MATTIAS EK, PETER CHEN, JITENDRA MANOCHA, JOÃO SOARES While service exposure has played a notable role in previous generations of mobile technology – by enabling roaming, for example, and facilitating payment and information services over the SMS channel – its role in 5G will be much more prominent. ■ Thehighexpectationsonmobilenetworks continuetorise,withnever-endingrequestsfor higherbandwidth,lowerlatency,increased predictabilityandcontrolofdevicestoservea varietyofapplicationsandusecases.Atthesame time,wecanseethatindustriessuchashealthcare andmanufacturinghavestarteddemandingmore customizedconnectivitytomeettheneedsoftheir services.Whilesomeofthesedemandscanbemet throughimprovednetworkconnectivitycapabilities, thereareotherareaswherethoseimprovements alonewillnotbesufficient.

SUCHASCENARIO...[ENABLES] TELECOMOPERATORSTOBECOME PARTOFTHEVALUECHAINOFTHE CLOUDCOMPUTINGMARKET Defining exposure Exposure in the IT/telecom sphere can be divided into a number of subareas. Data exposure is the process by which any kind of consumer (human or machine) can access data in a system via secure and controlled mechanisms. Data is normally exchanged in one direction only. Common examples of data exposure include accessing data via an application programming interface (API), downloading a file or retrieving observations from a server. Service exposure goes beyond data exposure to also include the ordering of execution of operations in the underlying system. Using an API to initiate operations and/or processes is a good example of service exposure. Services can be invoked bidirectionally by triggering events, for example. Data can also be updated via a service. Service exposure can be applied in a domain, as in network exposure, which exposes both data and services of the network. Enterprise resource planning (ERP) and customer relationship management (CRM) are other examples of domains where service exposure can be applied. To maintain security, the details of the underlying system are typically hidden in exposure scenarios.
