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.

What is claimed is: 1. An apparatus for configuring a layer or protocol prior to commencement of data communication by a first entity, the apparatus comprising: means for 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; means for determining, for each attribute, a list of selected attribute values that includes one or more attribute values considered acceptable to the first entity; means for sending from the first entity a list of selected attributes and their associated lists of selected attribute values; means for 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 means for 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. 2. The apparatus 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. 3. The apparatus of claim 1, wherein each processed attribute value is associated with one processed attribute value. 4. The apparatus 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. 5. The apparatus of claim 1, wherein the sending and receiving are achieved via dedicated communications channels. 6. The apparatus 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. 7. The apparatus 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. 8. The apparatus 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. 9. The apparatus 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. 10. The apparatus 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. 11. The apparatus 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 more protocols in the first entity. 12. The apparatus of claim 1, further comprising: means for receiving an entity identifier at the first entity, and wherein subsequent messages sent from the first entity are identified by the entity identifier. 13. The apparatus of claim 1, wherein the first entity and the second entity each selects a set of attributes to be negotiated, and wherein the negotiation of the set of attributes selected by the first entity is completed prior to the negotiation of the set of attributes selected by the second entity. 14. The apparatus of claim 1, wherein the first entity is an access terminal. 15. The apparatus of claim 1, wherein the second entity is a radio network. 16. The apparatus of claim 1, further comprising: means for sending from the first entity an open-request message indicative of a request to open a communications session; and means for receiving at the first entity an open-response message indicative of an acceptance or rejection of the request to open the communications session. 17. The apparatus of claim 16, wherein the open-request message and the open-response message are sent and received via common communications channels. 18. An apparatus for providing configurable layers or protocols, or both, in a communications system, the apparatus comprising: means for maintaining a set of default layers and protocols for use at a first entity to communicate with a second entity; means for maintaining a set of one or more configurable layers and one or more configurable protocols, or a combination thereof, wherein each configurable layer and protocol corresponds to an attribute that can be negotiated between the first entity and the second entity; means for providing a set of configuration messages used for sending and receiving configuration information related to each attribute; and means for providing a state machine indicative of a communications state of the first entity. 19. The apparatus of claim 18, wherein the configuration messages are implemented at a session layer of the communications system. 20. The apparatus of claim 18, wherein the set of default layers and protocols includes an overhead protocol for sending and receiving messages that support negotiation and configuration of a set of configurable attributes. 21. The apparatus of claim 18, wherein the state machine includes: an inactive state indicative of inactivity prior to a session negotiation, an initiated state indicative of the negotiation over one or more of the attributes, and an open state indicative of active communication between the first entity and the second entity. 22. The apparatus of claim 18, wherein each configuration message includes an entity identifier that identifies the first entity. 23. The apparatus of claim 18, wherein each configuration message includes a transaction identifier that identifies a particular instance of the configuration message.
