If you don't want to connect your laptop directly to the phone via USB (which is called tethering as inzone stated) you can enable wifi hotspot on your phone and then any wireless client can connect and use the cell phones internet connection. Your phone company will have to enable that on your phone though.

Assuming your cellphone has access to the internet and the ability for it to be used as a hotspot, you don't need a "d-link" or any other device.

Tethering can be by hard-wire or wireless, same thing.

The main thing you will need to do, if the phone is capabble, is to enable the tethering (aka hotspot) function. Phones with stock firmware typically lock this function in order to make you pay for it. Although, a rooted phone with a custom ROM will allow you to connect to the phones hotspot feature without the need of any further work on your part.

Again, this is under the assumption your phone even has these capabilities.
 
What you can also do is set your cell phone up as a wireless router and there are apps for that both free and pay. That way you don't need the router unless you are trying to connect more devices and you need more range. But if it's just the laptop then you can just download the app for wireless router and put the cell phone near the laptop (same room) and connect.
