摘要

Techniques for creating a service slice of a network in an underserved area are presented. A vehicle can be associated with a slice component that can generate service slices of a service network for various services. The vehicle can travel to an underserved area that does not have adequate wireless coverage or advance capabilities. For a communication device associated with an entity located in an underserved area, slice component can generate a service slice to connect the communication device to the communication network (and service network), establish a session with the communication device, provide applications, including VNF applications, to the communication device, and communicate information between the communication device and communication network (and service network). If no radio access to the network is available, slice component can continue the session with an internal slice and store information in its service database, which is synced when reconnected to the network.

As used herein, “5G” can also be referred to as New Radio (NR) access. Accordingly, systems, methods, and/or machine-readable storage media for instantiating slices (e.g., service slice, core slice) of a 5G or other next generation service network in an underserved area, can be desired. As used herein, one or more aspects of a 5G network can comprise, but is not limited to, data rates of several tens of megabits per second (Mbps) supported for tens of thousands of users; at least one gigabit per second (Gbps) that can be offered simultaneously to tens of users (e.g., tens of workers on the same office floor); several hundreds of thousands of simultaneous connections supported for massive sensor deployments; spectral efficiency that can be significantly enhanced compared to 4G; improvement in coverage relative to 4G; signaling efficiency that can be enhanced compared to 4G; and/or latency that can be significantly reduced compared to LTE.

Multiple Input, Multiple Output (MIMO) technology can be employed in communication networks, wherein MIMO technology can be an advanced antenna technique utilized to improve spectral efficiency and, thereby, boost overall system capacity. Spectral efficiency (also referred to as spectrum efficiency or bandwidth efficiency) refers to an information rate that can be transmitted over a given bandwidth in a communication system.

For MIMO, a notation (M×N) can be utilized to represent the MIMO configuration in terms of a number of transmit antennas (M) and a number of receive antennas (N) on one end of the transmission system. Examples of MIMO configurations used for various technologies can include: (2×1), (1×2), (2×2), (4×2), (8×2) and (2×4), (4×4), (8×4). The configurations represented by (2×1) and (1×2) can be special cases of MIMO known as transmit and receive diversity.
