Abstract
A method and system for retry of a packet data call. The method can include the steps of attempting () an IP registration with a mobile unit () to make a packet data call using a first protocol on a network () that employs both the first protocol and a second protocol for packet data calls and detecting () a failure in the IP registration using the first protocol due to a failure in a data link layer of the first protocol. A physical layer of the first protocol is unaffected by the failure in the data link layer of the first protocol such that communications may still be performed over the physical layer. The method can also include the steps of—at the mobile unit—ceasing () the attempted IP registration using the first protocol on the network and attempting () an IP registration with the mobile unit using the second protocol of the network. As an example, the first protocol can be EVDO, and the second protocol can be 1X.
