Apparatus and method for connection establishment in a communications network

An apparatus for establishing a connection in a communications network comprising a processor and a memory, the memory comprising program code executable by the processor to perform:

• reserving a common connection for use by an access terminal (AT) while deleting one or more AT-specific contexts associated with the AT when the AT is not in an active call or data connection, wherein the AT is one of a plurality of ATs reserving the common connection, wherein the common connection is an A10 connection established between an access node (AN) and a packet data switching node (PDSN), wherein the common connection includes a common mobile Internet Protocol (MIP) tunnel established between the PDSN and an Internet Protocol (IP) network-side element, and wherein the IP network-side element is one of a home agent (HA), a local mobility anchor (LMA), or a call originator gateway component;
• associating the common connection with a network identifier corresponding to the AT for reaching the AT, wherein the associating is performed based on a registration session by the AT;
• and
• transmitting a message, based on a call to the AT, via the common connection and based on the network identifier, wherein a specific connection and a context for the network identifier corresponding to the AT for carrying the call are established based on a response to the message.

• means for associating the common connection with a network identifier corresponding to the AT for reaching the AT, wherein the associating the common connection is based on a registration session by the AT;
• and
• means for transmitting a message, based on a call to the AT, via the common connection and based on the network identifier, wherein a specific connection and a context for the network identifier corresponding to the AT for carrying the call are established based on a response to the message, wherein a specific connection and a context for the network identifier corresponding to the AT for carrying the call are established based on a response to the message.

A non-transitory computer readable medium storing computer executable code for establishing a connection in a communications network, comprising:

• code for causing a computer to reserve a common connection for use by an access terminal (AT) while deleting one or more AT-specific contexts associated with the AT when the AT is not in an active call or data connection, wherein the AT is one of a plurality of ATs reserving the common connection, wherein the common connection is an A10 connection established between an access node (AN) and a packet data switching node (PDSN), wherein the common connection includes a common mobile Internet Protocol (MIP) tunnel established between the PDSN and an Internet Protocol (IP) network-side element, and wherein the IP network-side element is one of a home agent (HA), a local mobility anchor (LMA), or a call originator gateway component;
• code for causing the computer to associate the common connection with a network identifier corresponding to the AT for reaching the AT, wherein the associating is performed based on a registration session by the AT;
• and
• code for causing the computer to transmit a message, based on a call to the AT, via the common connection and based on the network identifier, wherein a specific connection and a context for the network identifier corresponding to the AT for carrying the call are established based on a response to the message.
