Abstract
Abstract The layers and protocols of an air interface layering architecture are designed to be modular and can be modified and upgraded to support new features, perform complex tasks, and implement additional functionality. Prior to commencement of data communication between a first entity (e.g., an access terminal) and a second entity (e.g., a radio network), a set of layers and/or protocols is selected for negotiation. For each selected layer and protocol (i.e., each attribute), a list of attribute values considered acceptable to the first entity is determined. The selected attributes and their associated attribute values are sent from the first entity and, in response, a list of processed attributes and their associated lists of processed attribute values are received. Each list of processed attribute values includes attribute values considered acceptable to the second entity. The layers and protocols in the first entity are then configured in accordance with the received list of processed attributes and their associated processed attribute values. Other features related to configurable layers and protocols are also provided.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
179 words
A method for configuring a layer or protocol prior to commencement of data communication by a first entity the method comprising: selecting at the first entity a set of one or more layers and one or more protocols to be negotiated, wherein each selected layer and protocol corresponds to an attribute to be negotiated between the first entity and a second entity; for each attribute, determining a list of selected attribute values that includes one or more attribute values considered acceptable to the first entity; sending from the first entity a list of selected attributes and their associated lists of selected attribute values; receiving at the first entity the list of processed attributes and their associated lists of the processed attribute values, wherein each list of processed attribute values includes one or more attribute values considered acceptable to the second entity; and configuring the selected set of one or more layers and one or more protocols in the first entity in accordance with the received list of the processed attributes and their associated lists of the processed attribute values.
Claim 2
Independent Claim
179 words
A method for configuring a layer or protocol prior to commencement of data communication by a first entity the method comprising: selecting at the first entity a set of one or more layers and one or more protocols to be negotiated, wherein each selected layer and protocol corresponds to an attribute to be negotiated between the first entity and a second entity; for each attribute, determining a list of selected attribute values that includes one or more attribute values considered acceptable to the first entity; sending from the first entity a list of selected attributes and their associated lists of selected attribute values; receiving at the first entity the list of processed attributes and their associated lists of the processed attribute values, wherein each list of processed attribute values includes one or more attribute values considered acceptable to the second entity; and configuring the selected set of one or more layers and one or more protocols in the first entity in accordance with the received list of the processed attributes and their associated lists of the processed attribute values.
Claim 3
Dependent Claim
28 words
The method of claim 1 , wherein elements in each list of the selected attribute values are arranged in an order based on preference of the first entity.
Claim 4
Dependent Claim
18 words
The method of claim 1 , wherein each processed attribute value is associated with one processed attribute value.
Claim 5
Dependent Claim
33 words
The method of claim 1 , wherein the layers and protocols in the first entity are configured with their default values if corresponding processed attribute values are not received at the first entity.
Claim 6
Dependent Claim
17 words
The method of claim 1 , wherein the sending and receiving are achieved via dedicated communications channels.
Claim 7
Dependent Claim
68 words
The method of claim 1 , wherein the first entity or the second entity, or both, implements a state machine having a plurality of states including: an inactive state indicative of inactivity prior to a session negotiation, an initiated state indicative of the session negotiation over the list of the selected attributes, and an open state indicative of active communication between the first entity and the second entity.
Claim 8
Dependent Claim
46 words
The method of claim 6 , wherein the initiated state includes: an access terminal initiated state indicative of the session negotiation over attributes selected by the first entity, and a radio network initiated state indicative of the session negotiation over attributes selected by the second entity.
Claim 9
Dependent Claim
34 words
The method of claim 1 , wherein the list of the selected attributes and their associated lists of the selected attribute values are sent from the first entity via one or more configuration-request messages.
Claim 10
Dependent Claim
35 words
The method of claim 1 , wherein the set of the processed attribute values and their associated lists of the processed attribute values are received at the first entity via one or more configuration-response messages.
Claim 11
Dependent Claim
42 words
The method of claim 1 , wherein the processed attribute values and their associated lists of the processed attribute values are received in an order corresponding to an order of the selected attributes and their associated lists of the selected attribute values.
Claim 12
Dependent Claim
46 words
The method of claim 1 , wherein the communication between the first entity and the second entity occurs via default layers and protocols prior to completion of configuration of the selected set of one or more layers and one or mores protocols in the first entity.
Claim 13
Dependent Claim
31 words
The method of claim 1 , further comprising: receiving an entity identifier at the first entity, and wherein subsequent messages sent from the first entity are identified by the entity identifier.
Claim 14
