Signaling transport over a bearer network for low latency services
First Claim
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.

Abstract
A wireless communication network is disclosed comprising a base station system, a switching system, and a transport network. The transport network comprises a conventional signaling network configured to transport call signaling and a bearer network configured to transport user communications. The bearer network also transports call signaling, as special connections are established and a portion of the capacity of the special connections are reserved for transporting call signaling. In response to receiving call signaling from a mobile wireless device or a packet data network, the base station system or the switching system determines if the call signaling is for a low latency service. If the call signaling is for a low latency service, then the base station system or the switching system forwards the call signaling over the special connection. If not, then the base station system or the switching system transmits the call signaling over the conventional signaling network.
