Method, apparatus and system for establishing connection
First Claim
1. A method for establishing a connection, comprising:
- generating, by a mobility management entity (MME) in a system architecture evolution (SAE), a create bearer context request message; and
sending, by the MME, the create bearer context request message to a selected serving gateway in the SAE, wherein the create bearer context request message comprises an address of a packet data network gateway (PDN GW) and information of a protocol type that is supported by the PDN GW and is used for an interface between the selected serving gateway in the SAE and the PDN GW.

Abstract
A method for establishing a connection is provided. The method 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. A mobility management entity, a serving gateway, and a network system which are able to reduce time delay when connection is established are further provided.

3. A method for establishing a connection, comprising:
-
receiving, by a serving gateway in a system architecture evolution (SAE), a create bearer context request message from a mobility management entity (MME) in the SAE; obtaining, by the serving gateway, from the received create bearer context request message, an address of a packet data network gateway (PDN GW) and information of a protocol type that is supported by the PDN GW and is used for an interface between the serving gateway in the SAE and the PDN GW; determining, by the serving gateway, that the protocol type is a General Packet Radio Service Tunneling Protocol (GTP), a Proxy Mobile IP Protocol (PMIP) or a Client Mobile IP Protocol (CMIP); and processing, by the serving gateway, the create bearer context request message based on the protocol type. - View Dependent Claims (4, 16, 17, 18, 19, 20, 21)

5. A method for establishing a connection, implemented in a system comprising at least a mobility management entity, a serving gateway, and a packet data network gateway, the method comprising:
-
generating, by the mobility management entity, a create bearer context request message and sending the create bearer context request message to the serving gateway, wherein the create bearer context request message comprises an address of the packet data network gateway and information of a protocol type that is supported by the packet data network gateway and is used for an interface between the serving gateway and the packet data network gateway; receiving, by the serving gateway, the create bearer context request message, obtaining, by the serving gateway, the address of the packet data network gateway and the information of the protocol type, and determining, by the serving gateway, that the protocol type is a General Packet Radio Service Tunneling Protocol (GTP), a Proxy Mobile IP Protocol (PMIP) or a Client Mobile IP Protocol (CMIP); and processing, by the serving gateway, the create bearer context request message based on the packet type. - View Dependent Claims (6)
