The mobile station selects a downlink frequency from among the M downlink frequencies and selects an uplink frequency from among the N uplink frequencies, independently of the downlink frequency. To make these selections, the mobile station may use a downlink hashing algorithm to map an identifier of the mobile station (such as MDN, MIN, IMSI, or ESN) to one of the M downlink frequencies and an uplink hashing algorithm to map the identifier to one of the N uplink frequencies."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for selecting uplink and downlink frequencies","description":"A mobile station receives at least one frequency listing that identifies M downlink frequencies that may be used to receive communications from a wireless telecommunications network and N uplink frequ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8509792","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
