Latency reduction in wireless service
Systems and methods presented herein provide latency reduction in wireless service through a communication link. In one embodiment, a method includes linking a modem to a Modem Termination System (MTS) via the communication link and detecting, at the modem, a message from a wireless service link indicating that a user equipment (UE) has data to transmit to a Mobile Network Operator (MNO). The method also includes requesting a data transfer from the modem to the MTS in response to detecting the message from the wireless service link and processing the request from the modem at the MTS. The method also includes granting the request while the UE is negotiating with the wireless service link to transmit the data of the UE.
1. A method for reducing latency between a wireless user device and a wireless core network via a parallel communication backhaul system utilizing parallel request-grant procedures, comprising:
detecting, at a small cell, a request to transmit data to the wireless core network initiated by the wireless user device;
processing the request to generate a first grant to transfer a first data; and
transmitting, within a first time window, an upstream and a downstream communication, the upstream communication including forwarding a copy of the request to the parallel communication backhaul system and the downstream communication including transmitting the first grant to the wireless user device for processing;
wherein processing the copy of the request by the parallel communication backhaul system to generate a second grant is completed prior to the receipt of a copy of a buffer status report (BSR) from the small cell and originating from the wireless user device.
2. The method of claim 1 , wherein processing the copy of the request by the parallel communication backhaul system to generate a second grant comprises,
receiving the copy of the request at a modem;
processing the request to generate a Modem Termination System (MTS) request;
transmitting the MTS request to an MTS for processing and generating of second grant; and
receiving the second grant.
3. The method of claim 1 , wherein the wireless user device comprises an LTE enabled user equipment (UE).
4. The method of claim 1 , wherein the wireless core network comprises a Mobile Network Operator's (MNO) mobile core network.
5. The method of claim 1 , wherein the parallel communication backhaul system is selected from the group consisting of a DOCSIS network, a satellite communication network, a Digital Subscriber Line (DSL) network, and an optical network.
6. The method of claim 1 , wherein the first data is a buffer status report (BSR).
7. The method of claim 6 , wherein the request to generate a grant to transfer the BSR is processed after a copy of the request is forwarded to the parallel communication backhaul system.
8. The method of claim 1 , wherein the wireless core network comprises a Wi-Fi core network.
