Abstract:
1. A gateway selection method during heterogeneous network handover, comprising: accessing, by a terminal, a first access network; obtaining, by the terminal, an equipment identity of a first core network element; accessing, by the terminal, a second access network, wherein the second access network and the first access network are heterogeneous networks; sending, by the terminal, the obtained equipment identity of the first core network element to a second core network element, such that when an equipment identity of the second core network element is different from the equipment identity of the first core network element, the second core network element selects the first core network element as a target gateway in order that the terminal is handed over to the target gateway to maintain session continuity in first access network; wherein the equipment identity of the first core network element comprises: a gateway identity uniformly allocated by an operator during network deployment; or a fully qualified domain name (FQDN); or a prefix and an identity that are added in an APN.
