Description

METHOD AND APPARATUS FOR COORDINATED SERVICE RECOVERY IN WIRELESS NETWORK

The present disclosure relates to the field of communication technologies. Particularly, but not exclusively, the present disclosure relates to method and apparatus for coordinated service recovery.

5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in “Sub 6GHz” bands such as 3.5GHz, but also in “Above 6GHz” bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

Moreover, there has been ongoing standardization in air interface architecture/protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture/service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

In general, an energy utility provider as a distribution system operator (DSO) station is a natural or legal person who is responsible for operating, ensuring the maintenance of and, if necessary, developing a distribution system in a given area and, where applicable, its interconnections with other systems, and for ensuring a long-term ability of the distribution system to meet reasonable demands for the distribution of electricity.

The delivery of electrical energy must occur with extreme levels of availability. It is crucial in a domain, for regulatory, business and public health and safety requirements. To achieve reliable availability, a range of 'smart energy services' is employed by an energy system. The smart energy services, largely standardized by Institute of Electrical and Electronics Engineers (IEEE) and International Electrotechnical Commission (IEC), require communication. As greater degrees of efficiency, resiliency, responsiveness and other capabilities are sought in the generation and delivery of electricity, more and more communications services are required by an electrical energy sector. To the extent that the third generation partnership project (3GPP) communication system can provide services that meet the needs of the electrical energy sector, telecommunications will be an increasingly important part of a technical ecosystem by which electricity is delivered.

Moreover, a mobile telecommunications network require energy, so may also suffer a communications service outage when the DSO station`s energy supply system goes faulty. There is clearly a mutual interest in coordination between Mobile Network Operation (MNO) telecommunications and DSO's energy service operations to achieve rapid recovery of the energy service outage. This is not only true for a MNO device, who benefits from the availability of supplied power, but also for the energy utility the service provider who needs a mobile telecommunication service to restore and maintain an operation of its grid.

Currently, disaster recovery plans are 'static' and data exchanged is not standards based. The energy utility provider (e.g., DSO station) knows when and where outage has occurred and when telecommunication services are critically important for the recovery. The MNO device knows their uninterruptable power supply resources and the possibility of utilizing telecommunication services to enable utility's energy system rapid recovery via the smart energy services such as for example supervisory control and data acquisition (SCADA). However, there is no standardized mechanism to share all the information between the DSO station and MNO device to enable efficient usage of the smart energy services for the service recovery. The energy utility provider (e.g., DSO station or the like) can restore energy distribution services without smart energy services, but the utility provider requires substantially longer time as it often requires manual intervention by a technician who must travel to energy distribution substations to restore the service.

So, there is a requirement of a coordinated service recovery in the network performance management. Thus, it is desired to address the above mentioned disadvantages or other shortcomings or at least provide a useful alternative.

The principal object of the embodiments herein is to perform a coordinated service recovery in network performance management. The coordinated service recovery in the network performance management is ensured by performing mutual exchange of information between a third party energy utility provider (e.g., DSO station or the like) and a MNO device using standardized interfaces exposed by a Third Generation Partnership Project (3GPP) network management system for rapid recovery of utility's energy service outage and subsequent fallback by the MNO device from its uninterrupted power supply (UPS) to utility's energy supply for MNO device communications service/network operations.

Further, the DSO station informs about the energy service outages like time of outage, locations, expected recovery time etc. The MNO device has information on a state of its power backup i.e. UPS backup duration at different base station locations, base station identifier (ID) that are enduring DSO's power outage and are depending on the UPS backup, base stations that provide communications services to DSOs substations for smart energy services implementation etc.

Another object of the embodiments herein is to provide that MNOs Rapid Intervention (MRI) is an approach by which the DSO station seeks dedicated communication service support from the MNO device using the UPS backup for network operations. The DSO station uses automated smart energy services like SCADA for rapid recovery of the energy distribution services.
