Optimization of 3GPP standards that apply to cellular technologies and their adaptation to LPWAN has not led to positive results only enabling to compete on the market with the growing number non-cellular greenﬁeld LPWAN technologies – LoRa, Sigfox and others. The need to take into consideration, during the 3GPP standard optimization phase, the low-cost segment of narrow-band IoT devices relying on such new technologies as LTE-M, NB-IoT and EC-GSM, has also led to a loss of a number of technical characteristics and functions that offered low latency and guaranteed the quality of service. The aim of this article is therefore to review some of the most technical limitations and restrictions of the new 3GPP IoT technologies, as well as to indicate the direction for development of future standards applicable to cellular IoT technologies.

PL

W czerwcu ubiegłego roku organizacja standaryzacyjna 3GPP przyjęła nowy standard wąskopasmowej transmisji NB IoT dla Internetu Rzeczy, realizowanej w szerokopasmowych sieciach LTE. Moduły radiowe tego standardu Cat. NB1 będą tanie, co otwiera szeroki rynek dla urządzeń IoT przekazujących umiarkowane ilości danych. W pracy przedstawiono główne parametry systemu NB IoT oraz jego przewidywane zastosowania. Badano także poziom RSSI wewnątrz budynku i w terenie miejskim dla testowej instalacji systemu NB IoT.

EN

In June last year the organization of telecommunication standards 3GPP adopted a new narrowband standard NB IoT for broadband LTE networks. Radio modules of this standard Cat. NB1 will be cheap which opens up a wide market for IoT devices transferring moderate amounts of data. In this paper the main parameters of NB IoT system and its typical applications were presented. The RSSI level inside building and at urban area for a test NB IoT installation was also investigated.

The IP Multimedia Subsystem is a telecommunications framework with a standard architecture for the provision of services. While the services themselves have not been standardised, standards do exist for basic technologies that can be re-used and aggregated in order to construct more complex services. These elements are called service capabilities by the 3GPP and service enablers by the OMA, both of which are reputable standards bodies in this area. In order to provide re-usability, there is a need to manage access to the service capabilities. Also, in order to build complex services, there is a further need to be able to manage and coordinate the interactions that occur between service capabilities. The 3GPP and the OMA have separately defined network entities that are responsible for handling aspects of these requirements, and are known as a service capability interaction manager (SCIM) and a policy enforcer respectively. However, the internal structure of the SCIM and the policy enforcer have not been standardised by the relevant bodies. In addition, as the SCIM and the policy enforcer have been defined through complementary yet separate processes, there is an opportunity to unify efforts from both bodies. This paper builds on work and standards defined by the bodies, and proposes the design of an interaction manager with features borrowed from both the SCIM and the policy enforcer. To help validate the design, we have identified a platform known as JAIN SLEE which we believe conforms to the model proposed, and we discuss how JAIN SLEE can be used to implement our ideas.
