Methods and apparatus for expression use during d2d communications in a lte based wwan

A method of wireless communications, comprising:

• sending a connection request, to a mobility management entity (MME), to establish a communication link between a first user equipment (UE) and a second UE based on a first expression pair;
• receiving at least a portion of information associated with a first context between the first UE and the second UE based on a previously established communication link with a previously used expression pair;
• and
• establishing, by the first UE, the communication link with the second UE using the received at least a portion of the information.

An apparatus for wireless communication, comprising:

• means for receiving, by a mobility management entity (MME), a request from a first user equipment (UE) to establish a communication link with a second UE based on a first expression pair;
• means for determining whether the first UE and the second UE can use a first context associated with a previously established communication link based on a previously used expression pair;
• and
• means for providing at least a portion of information associated with the first context to the first UE upon a determination that the first UE and the second UE have the first context.

A computer program product, comprising:

• a computer-readable medium comprising code for:
• receiving, by a mobility management entity (MME), a request from a first user equipment (UE) to establish a communication link with a second UE based on a first expression pair;
