A network site connected to the user equipment monitors a quality of a signal between the network site and the user equipment and receives movement information from the user equipment. The network site selects a potential network site for the handoff of the user equipment based on the movement information and a potential signal quality between the user equipment and the potential network site. The network site coordinates the handoff and causes the selected potential network site to transmit a handoff instruction to the user equipment. The network site also instructs the user equipment to listen for the handoff instruction and the user equipment and potential network site can complete the handoff. ## Claims ### Claim 1 A method, comprising: receiving movement information from a user equipment, the movement information including at least one of a location of the user equipment, a speed of the user equipment and a direction of the user equipment; determining a quality of a signal between the user equipment and a current site to which the user equipment is connected; determining whether to initiate a handoff of the user equipment based on: the movement information, and the quality of the signal between the user equipment and the current site; and a network map that includes multiple network sites that are nearby or surrounding the user equipment or the current network site; analyzing a potential signal quality of a signal response for each of the multiple networks sites in the network map, each analysis of the potential signal quality based on a transmission received from the user equipment; identifying a potential network site of the multiple networks sites based on the analysis of the potential signal quality of the signal response for each of the multiple network sites in the network map, selecting the potential network site for the handoff based on the analysis of the potential signal quality and a characteristic or parameter of the network; transmitting an instruction to the potential network site via a communication pathway that is unusable by or inaccessible to the user equipment, the instruction to the potential network site including an instruction to initiate handoff of the user equipment to the potential network site; and based on the transmitted instruction to initiate the handoff of the user equipment to the potential network site, causing the potential network site to output a handoff instruction to the user equipment to initiate the handoff of the user equipment to the potential network site. ### Claim 2 (depends on 1) The method of claim 1, wherein the movement information from the user equipment is received at a variable frequency. ### Claim 3 (depends on 1) The method of claim 1, wherein the quality of the signal is a loudness of the signal between the user equipment and the current site to which the user equipment is connected. ### Claim 4 (depends on 1) The method of claim 1, wherein the movement information includes a location of the user equipment, and further comprising determining a location of the user equipment relative to the potential network site, and wherein the determining whether to initiate the handoff of the user equipment to the potential network site is further based on the location of the user equipment relative to potential network site. ### Claim 5 (depends on 4) The method of claim 4, wherein the movement information includes a direction of the user equipment, and wherein the determining whether to initiate the handoff of the user equipment to the potential network site is further based on the direction of user equipment. ### Claim 6 (depends on 1) The method of claim 1, further comprising instructing the user equipment to listen to a common channel for the instruction to initiate the handoff of the user equipment, and wherein the potential network site transmits the received instruction to initiate the handoff of the user equipment on the common channel. ### Claim 7 A predictive handoff system for user equipment, comprising: a connected network site, including: a user equipment communication module configured to monitor a signal quality of a signal between a user equipment and the connected network site and to receive movement information from the user equipment; a handoff module configured to: evaluate the signal quality of the connected network site; analyze a potential signal quality of a signal response for each of multiple networks sites within a network map, the network map including the multiple network sites that are nearby or surrounding the user equipment or the current network site; identify a potential network site of the multiple network sites based on the analysis of the potential signal quality of the signal response for each of the multiple network sites in the network map; select the potential network site for a handoff based on the analysis of the potential signal quality and a characteristic or parameter of the network; generate an instruction to initiate the handoff of the user equipment to the selected potential network site based on the analysis of the potential signal quality and a characteristic or parameter of the network, a network site communication module configured to transmit the instruction to initiate the handoff of the user equipment over a communication pathway that is unusable by or inaccessible to the user equipment; and a potential network site, including: a network site communication module configured to receive the instruction from the connected network site over the communication pathway, the instruction causing the selected potential network site to initiate the handoff of the user equipment to the selected potential network site, wherein, based on the transmitted instruction to initiate the handoff of the user equipment to the selected potential network site, the selected potential network site is further configured to output the handoff instruction to the user equipment to initiate the handoff of the user equipment to the selected potential network site. ### Claim 8 (depends on 7) The predictive handoff system of claim 7, wherein the characteristic of the potential signal quality is a loudness of a signal between the user equipment and the respective potential network sites. ### Claim 9 (depends on 7) The predictive handoff system of claim 7, wherein the movement information includes at least one of a location of the user equipment, a speed of the user equipment and a direction of the user equipment. ### Claim 10 (depends on 9) The predictive handoff system of claim 9, wherein the movement information is received on a schedule. ### Claim 11 (depends on 10) The predictive handoff system of claim 10, wherein the schedule is variable and based on one or more of the location of the user equipment, the speed of the user equipment and the direction of the user equipment. ### Claim 12 (depends on 7) The predictive handoff system of claim 7, wherein the network site communication module is further configured to coordinate the handoff with the potential network site by causing the potential network site to output the handoff instruction to the user equipment to cause the user equipment to connect to the potential network site. ### Claim 13 (depends on 12) The predictive handoff system of claim 12, wherein the network site communication module is further configured to coordinate the handoff with the user equipment by causing the user equipment communication module to output an instruction for the user equipment to listen on a common channel for the instruction to initiate the handoff instruction.
