Multi-Band Multi-RAT Cell Search - A simplified explanation of the abstract
This abstract first appeared for US patent application 17934677 titled 'Multi-Band Multi-RAT Cell Search
Simplified Explanation
The abstract describes a user equipment (UE) that can determine the bands on which a mobile network is expected to be deployed and select a search pattern for cell search. If the initial search is unsuccessful, the UE can perform a second phase of the search by scanning frequencies in different bands.
- The UE determines a list of bands where a mobile network is expected to be deployed based on its current location and network deployment information.
- The UE selects a search pattern for cell search based on its current scenario.
- The UE performs a first phase of the cell search and if no cell is selected, it proceeds to a second phase.
- In the second phase, the UE scans frequencies in either the first list of bands for a second priority radio access technology (RAT) or the second list of bands for the first priority RAT.
Potential applications of this technology:
- Mobile devices and smartphones can benefit from improved cell search capabilities, ensuring better connectivity and network access.
- Network operators can enhance their network deployment strategies by considering the expected bands for different regions, leading to more efficient network coverage.
Problems solved by this technology:
- The technology addresses the issue of unsuccessful cell search in mobile devices by providing a two-phase search approach.
- It solves the problem of limited network coverage in certain bands by allowing the UE to scan frequencies in bands not included in the initial list.
Benefits of this technology:
- Improved connectivity: The UE can perform a more comprehensive cell search, increasing the chances of successful network connection.
- Enhanced network coverage: By considering the expected bands for different regions, network operators can optimize their network deployment and provide better coverage.
- Efficient spectrum utilization: The technology allows for scanning frequencies in bands that may not be included in the initial list, maximizing the utilization of available spectrum resources.
Original Abstract Submitted
A user equipment (UE) configured to determine, for each radio access technology (RAT) of a plurality of RATs, a first list of bands on which a public land mobile network (PLMN) is expected to be deployed and a second list of bands including bands not included in the first list, wherein the first list is determined based on a region where the UE is currently located and PLMN deployment information, select a search pattern for performing a cell search based on a current UE scenario, perform a first phase of the cell search and when the first phase of the cell search is unsuccessful and no cell is selected, perform a second phase of the cell search by either scanning frequencies included in the second list of bands for the first priority RAT or scanning frequencies included in the first list of bands for a second priority RAT.
