Method, apparatus and system for establishing a connection
First Claim
1. A method for establishing a connection, comprising:
- generating, by a mobility management entity, a create bearer context request message; and
sending, by the mobility management entity, the create bearer context request message to a selected serving gateway, wherein the create bearer context request message comprises address information of at least one packet data network gateway and indication information of at least one protocol type of connection establishment, and wherein the selected serving gateway selects a protocol type of connection from the at least one protocol type of connection for establishing the connection with the packet data network gateway, wherein the protocol type of connection establishment selected by the selected serving gateway is at least one of a General Packet Radio Service Tunneling Protocol (GTP), a Proxy Mobile IP Protocol (PMIP), and a Client Mobile IP Protocol (CMIP).

Abstract
A method for establishing a connection includes the following steps: A mobility management entity generates a create bearer context request message and sends the message to a selected serving gateway. The create bearer context request message at least includes address information of at least one packet data network gateway and corresponding indication information of the protocol type of connection establishment. The serving gateway receives and analyzes the create bearer context request message, and determines the protocol type of the connection according to the indication information of the protocol type of connection establishment. The serving gateway processes the create bearer context request message with the determined protocol type of connection. Further provided are a mobility management entity, a serving gateway, and a network system which are able to reduce time delay when connection is established.
