Abstract

Methods and systems automatically allocate cellular communication network resources to emergency response personnel during emergency situations which are detected by call volumes exceeding a predetermined maximum. Access to cellular communication network resources is provided by dedicating a portion of communication radio resources to emergency response personnel use. By reserving radio resources for emergency communication purposes, emergency personnel are able to both initiate and receive calls or data sessions from both other mobile devices as well as conventional landline telephone stations. Qualified emergency response personnel can preregistered their phones and be assigned personal identification numbers to enable access to allocated network resources. Users can also be registered “on the fly.”
