Methods and apparatus for expression use during D2D communications in a LTE based WWAN
First Claim
1. A method of communications, comprising:
- 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;
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;
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;
generating, by the MME, a second context for the communication link based on the first expression pair upon a determination that the first UE and the second UE do not have the first context; and
providing, by the MME, at least a portion of information associated with the generated second context to the first UE to establish the communication link based on the first expression pair upon the determination that the first UE and the second UE do not have the first context.

Abstract
A method, an apparatus, and a computer program product for wireless communication are provided in connection with use of expressions with D2D communications in a LTE based WWAN. In one example, a MME is equipped to receive a request from a first UE to establish a communication link with a second UE based on a first expression pair, determine whether the UEs can use a first context associated with previously used expression pair, and provide information associated with the first context to the first UE. In another example, a UE is equipped to send a connection request, to its MME, to establish a communication link with a second UE based on a first expression pair, receive at least a portion of information associated with a first context between the UEs based on a previously used expression pair, and establish the communication link with the second UE using the received information.

16. 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 if the first UE and the second UE have the first context; receiving, from the MME, at least a portion of information associated with a generated second context if the first UE and the second UE do not have the first context; and establishing, by the first UE, the communication link with the second UE using the received at least a portion of the information associated with the first context or the received at least a portion of information associated with the generated second context. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. 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, by the MME, 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, by the MME, 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, wherein the means for determining is further configured to generate a second context for the communication link based on the first expression pair upon a determination that the first UE and the second UE do not have the first context, and wherein the means for providing is further configured to provide at least a portion of information associated with the generated second context to the first UE to establish the communication link based on the first expression pair upon the determination that the first UE and the second UE do not have the first context. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
