Loopt location updating
Once the MS identifies its desired network, it sends a message to the network to indicate that it has entered into an idle state.The Visitor Location Register (VLR) checks its database to determine whether there is an existing record of the particular subscriber.The HLR is not informed of this and the VLR does not acknowledge the MS about the IMSI detach.If the radio link quality is poor when IMSI detach occurs, the VLR may not properly receive the IMSI-detach request.
Vd=function();function cj(a) C(cj, E);cj.prototype.kd=ea(1);cj.prototype. Oc=function(a);function dj(a) C(dj, E);var ej=;function fj(a) C(fj, E);fj.Style=function();function gj(a) C(gj, E);r=gj.prototype;r. In this situation the VLR performs an implicit IMSI detach.This procedure is used to update the location of the Mobile Station in the network and is described in more detail here.Instead, in the wild west of the mobile social networks, the key will be adoption. About Loopt Loopt actually launched back in 2006 after receiving funding from YCombinator as well as Series A from NEA and Sequioa.This is an area where Loopt is making headway, having recently announced deals with all the major U. Back then, it was only available to Boost Mobile customers as a Java mobile client.
When a mobile station registers in a new VLR, the subscriber's data is deleted from the previous VLR in a cancel location procedure.
