1. A wireless communication network configured to provide low latency services to mobile wireless devices, the wireless communication network comprising:
a transport network comprising:
a signaling network configured to transport call signaling; and
a bearer network configured to transport bearer traffic,
wherein a special connection on the bearer network is established and at least a portion of the capacity of the special connection is reserved for transporting call signaling for low latency services;
a base station system connected to the transport network, the base station system, responsive to receiving call signaling from a mobile wireless device, determines if the call signaling is for a low latency service, forwards the call signaling over the special connection on the bearer network if the call signaling is for a low latency service, and forwards the call signaling over the signaling network if the call signaling is not for a low latency service; and
a switching system connected to the transport network, the switching system, responsive to receiving the call signaling over the special connection on the bearer network or the signaling network, forwards the call signaling over a packet data network.
