Typically, subnets are fairly secure in segregating the network. To communicate with other subnets, routers are explicitly configured to share routing information about each subnet via routing protocols such as RIP, OSPF, EIGRP, etc. If you can't ping a host in another subnet, the only thing you can do is change the router configs. If "university network" means you don't have access to the equipment, then you're out of luck as far as I know.
