Never Pay For Texting Again With Kakaotalk [Android & iOS]

Text messaging is a relatively new form of communications for most people, but it is also one that’s surging towards massive popularity. There are many situations where quick messages are more convenient than phone calls.The only problem is the price. On most carriers, text messaging is a bit of a racket. Each message is literally no more than a few kilobytes in size, yet the price for 500 texts per month is often $15 or more. If you have a data plan however, Kakaotalk can make sure you never pay for texts again.

Leveraging The Internet

Part of the reason given for the expensive pricing of text messaging is the method used to communicate them. Rather than using the mobile broadband connection available on most smartphones, text messages utilize the same cellular network used for calls. This means there’s wider coverage, but there’s also less bandwidth, and that’s used to justify (accurately or not) the high prices.
A way to side-step this is to use mobile broadband instead, and that’s exactly what Kakaotalk does. In essence it operates like an instant messenger on a computer. So long as you have an Internet connection on your phone, you have free SMS texting.

Identical To SMS – Almost

What makes Kakaotalk a particularly nice solution to the problem of text messaging charges is the way it works. Although you can effectively do the same thing with other apps, such as imo.im, many of those apps give the definite “feel” of being a PC-like instant messenger with a mobile interface.

Kakaotalk, however, replicates the SMS interface on a typical smartphone. Conversations appear in the Chats tab of the interface, which appears very similar to the conversations tab of most Android SMS apps. The flow of the messages is the same, with user images appearing next to text bubbles, and the app triggers a notification sound and a message preview whenever you receive a new text.

In addition to texting, you can accomplish everything that would be provided by MMS. This includes pictures, video and audio clips. Indeed, the quality of multimedia sent via Kakaotalk will likely be higher, since MMS often cuts down the quality of media being transferred.
It’s also possible to invite multiple people to a text conversation, which I find can be handy in work situations where multiple people need to communicate, but can’t make a call because the work environment is either too quiet or too noisy.

UMTS Layer 3

UMTS Layer 3 pdf

RRC is located at Layer 3 in the control plane of the access stratum (AS). It resides in
the UE and the UTRAN – at the Node B (UE in idle mode) or SRNC (UE in connected
mode). RRC provides signalling transfer services to higher layers through service
access points (SAP). Higher layer signalling messages are encapsulated within RRC
messages for transmission over the radio interface. NAS higher layer entities using
the services of RRC in this way are:
• Call Control (CC), which deals with set-up, maintenance and clear-down of circuitswitched
calls.
• Session Management (SM), which deals with set-up, maintenance and clear-down
of pocket-switched sessions.
• Mobility Management (MM), which deals with all mobility issues involving tracking of
UEs as they move from area to area. Related to this is GPRS Mobility Management
(GMM) which does the same for packet-mode operation.
• Short Message Service (SMS), dealing with SMS message delivery.
