Publication number: 20130083646Abstract: Systems and techniques for management of network resource access attempts. In response to identifying that a radio bearer has failed, a radio resource associated with the radio bearer is released, either through request by a user equipment or direction by the network. Attempts at regaining access to the released radio bearer are inhibited during conditions recognized as potentially leading to excessively frequent unsuccessful attempts. Inhibition of attempts at regaining access to the released radio bearer may comprise imposing a backoff timer to inhibit reestablishing access to the released radio link for the duration specified by the backoff timer.Type: ApplicationFiled: September 30, 2011Publication date: April 4, 2013Inventors: Hannu Hietalahti, Steven FRANKLIN, Keiichi KUBOTA
