Abstract: This patent document describes, among other things, techniques, and apparatuses for providing multiple network connections to improve wireless network efficiency and performance. In one aspect, a method of wireless communication is disclosed. The method includes determining, by a network node, whether to include a paging cause indication in a paging message based on a rule. The method further includes transmitting, by the network node, the paging message according to the determining, wherein the rule specifies that: in case that the paging message is being transmitted due to a common paging cause, the paging cause indication is omitted, and in case that the paging message is being transmitted due to a different paging cause that is different from the common paging cause, the paging message is transmitted by indicating the different paging cause in the paging cause indication.
