Security management in disaggregated base station in communication system

#The field relates generally to communication systems, and more particularly, but not exclusively, to security management within such systems.

#This section introduces aspects that may be helpful in facilitating a better understanding of the inventions. Accordingly, the statements of this section are to be read in this light and are not to be understood as admissions about what is in the prior art or what is not in the prior art.

#Fourth generation (4G) wireless mobile telecommunications technology, also known as Long Term Evolution (LTE) technology, was designed to provide high capacity mobile multimedia with high data rates particularly for human interaction. Next generation or fifth generation (5G) technology is intended to be used not only for human interaction, but also for machine type communications in so-called Internet of Things (IoT) networks.

#FIG. 1 illustrates a communication system with which one or more illustrative embodiments are implemented.

#FIG. 2 illustrates user equipment and a base station configured for providing security management with which one or more illustrative embodiments are implemented.

#FIG. 3 illustrates an overall architecture for a disaggregated base station in a communication system with which one or more illustrative embodiments are implemented.

#Embodiments will be illustrated herein in conjunction with exemplary communication systems and associated techniques for providing security management in communication systems. It should be understood, however, that the scope of the claims is not limited to particular types of communication systems and/or processes disclosed. Embodiments can be implemented in a wide variety of other types of communication systems, using alternative processes and operations. For example, although illustrated in the context of wireless cellular systems utilizing 3GPP system elements such as a 3GPP next generation system (5G), the disclosed embodiments can be adapted in a straightforward manner to a variety of other types of communication systems.

#In accordance with illustrative embodiments implemented in a 5G communication system environment, one or more 3GPP technical specifications (TS) and technical reports (TR) provide further explanation of user equipment and network elements/functions and/or operations that interact with one or more illustrative embodiments, e.g., the above-referenced 3GPP TS 23.501, 3GPP TS 33.501, and 3GPP TR 33.899. Other 3GPP TS/TR documents provide other conventional details that one of ordinary skill in the art will realize. However, while illustrative embodiments are well-suited for implementation associated with the above-mentioned 5G-related 3GPP standards, alternative embodiments are not necessarily intended to be limited to any particular standards.

#Furthermore, illustrative embodiments will be explained herein in the context of the Open Systems Interconnection model (OSI model) which is a model that conceptually characterizes communication functions of a communication system such as, for example, a 5G network. The OSI model is typically conceptualized as a hierarchical stack with a given layer serving the layer above and being served by the layer below. Typically, the OSI model comprises seven layers with the top layer of the stack being the application layer (layer 7) followed by the presentation layer (layer 6), the session layer (layer 5), the transport layer (layer 4), the network layer (layer 3), the data link layer (layer 2), and the physical layer (layer 1). One of ordinary skill in the art will appreciate the functions and interworkings of the various layers and, thus, further details of each layer are not described herein. However, it is to be appreciated that while illustrative embodiments are well-suited for implementations that utilize an OSI model, alternative embodiments are not necessarily limited to any particular communication function model.
