`headset 14 from one or more devices associated with a local area network, without transmission to the mobile
`
`telephone 12, for decoding into an audio signalthat is broadcast by the speaker 24.
`As explained in detail below, audio data transmitted from the mobile telephone 12 to the headset 14
`and/or transmitted from one or more devices associated with a WLANto the headset 14 is typically in the form
`
`of media packets. Each media packet may contain a quantity of audio data, such as about 5 milliseconds of
`audio data. The audio data may be buffered by the buffer 62 and decoded by the decoder 60into an audiosignal
`for delivery to the speaker 24, As will be appreciated by oneofordinary skill in the art, the audio data may be
`
`mono, stereo or surround-sound, or arranged in any other suitable audio format.
`
`An exemplary communication network 100 in accordance with aspects of the present invention is
`
`illustrated in Figure 3. The exemplary networkillustrated in Figure 3 is a public wireless local area network,
`whichutilizes Internet Engineering Task Force (IETF) protocols (e.g., IP, TCP, UDP, RTP, HTTP and the like)
`between the endpoints (e.¢., the streaming source and rendering device (e.g., headset)),
`In this illustration, the
`mobile telephone 12 acts as a gateway or proxy for routing content (e.g., audio files, video files, etc.) stored on
`the server 102 through one or more routers 104 and an IP network 106, which may be any suitable network to a
`destination source. From the IP network 106 and, optionally, router 104, the multimedia content is transmitted
`
`to wired LAN 108, routed to the ACCESS POINT110, and outputto the destination source(e.g., mobile
`
`telephone 12 and/or rendering device 14) in a wireless manner.
`Although the server 102 is shown as being outside of the wired LAN 108, this is forillustrative
`purposes only. Oneofordinary skill in the art will readily appreciate that the server 102 may be located within
`the wired LAN 108 depending on the specific requirements of the server 102 and/or the LAN 108 or can be ona
`remote networkthat is connected to LAN 108 via the Intemet. One ofordinary skill in the art will also
`appreciate that the exemplary LAN 108 may be a wireless local area network, a wide area network, personal-
`area access technology (e.g., wireless local area network,cellular network, WiMax, ultra wideband network,

`
`$02.11 physical (PHY) layer 166 and an 802.11 medium access control (MAC) layer 168. The network layer
`
`152 and the WiFi layer 154 communicate with an authentication and security module 170. Likewise, the
`Bluetooth stack 153 may also communicate with the network layer 152 and the authentication and security
`module 170
`
`Referring to Figure 5B, an exemplary protocol stack 180 is illustrated for headset 14. The protocol
`
`stack 180 includes: a network layer 182, a WiFi layer 184 and a Bluetooth stack 185. The network layer 132
`
`includesa logic link layer 186, an Internet Protocol (IP) layer 188, a user datagram protocol (UDP)layer 190, a
`

`
`(RTP/RTCP)layer 194. The WiFi layer 184 includes an 802.11 radio frequency (RF) layer 196, an 802.11
`
`physical (PHY) layer 198 and an 802.11 medium access control (MAC) layer 200. The headphone 14 is capable
`
`of receiving and rendering Bluetooth signals and WiFi signals through the respective layers (e.g... Bluetooth
`
`10
`
`15
`
`20
`
`stack 185, WiFi layer 184).
`
`The mobile telephone 12 also includes dynamic host configuration protocol (DHCP)and network
`
`address translation (NAT) server functionality that is typically found in a network gateway. In this manner,
`
`devices peripheral to the mobile telephone 12, such as the headset 14 are treated as a subnet that is "hidden" to
`the network beyondthe gateway. By using DHCP and NAT,respectively, the mobile telephone assigns subnet
`
`IP addresses to the peripherals and directs incoming IP traffic (e.g., streaming audio) from the network to the
`
`proper peripheral(s) based on the assigned subnet addresses.
`
`An exemplary method 250 in accordance with aspects ofthe present invention is illustrated in Figure 6.
`
`Referring to Figures 3 and 6,at step 252, the user associates the headset 14 with the mobile telephone 12, The
`headset 14 is designated as the audio sink endpoint (e.g., rendering device) for rendering one or more audio
`components transmitted from server 102. The headset 14 becomes part of the private subnet and receives an IP
`
`address from the DHCPserver of the mobile telephone 12.
`
`At step 254, the mobile telephone 12 requests access to the network 100 through the access point 110.
`The request may include a session description protocol (SDP) payloadfield, which may specify, for example,
`negotiation parameters, services requested, format of information, etc.
`In the exemplary system illustrated in
`Figure 3, a public WLAN 100 is provided, wherein the user must be authenticated prior to access to the network
`100. Accordingly, at step 256, the request is routed to the AAA server 109 by one or moreredirect servers
`and/or proxy servers (not shown). The AAAserver 109 provides authentication services to the public network
`100. Assuming the user is properly authenticated, the user is provided access to the network 100, at step 258. If
`the user is unable to properly authenticate him or herself, the user is denied access to the public network 100.

`
`At step 260, an identification of available services and/or devices is provided to the mobile telephone
`12. Once network accessis established, at step 262, the user of the mobile telephone 12 may identify desired
`audio content and/or devices on a remote server 102. For example,this could be content stored on server 102
`(e.g., a personalserver, a personal computerin a home, a mediaserver, etc. or content froma commercial music
`service (e.g., iTunes, operatorportal, etc.)). The user selects the desired content to stream andinitiates a
`streaming session with the server 102. The mobile telephone 12 also configures the headset 14 to acceptthe
`pending media flow from the server 102.
`At step 264, the servertransmits the audio to the mobile telephone 12 using conventional IETF
`protocols (e.g., RTP, UDP andIP) over the network 100. At step 266, the mobile telephone 12 then forwards
`these packets to the headset 14, using NATto establish the correct address for the headset 14 in the internal
`subnet. At step 268, the headset 14 unpacks, decodes and rendersthe streaming audio in a user-sensible format
`through one or more speakers 24.
`In this example, session control is managed by the mobile telephone 12 while the media stream is
`established between the server and headset. Session control may occur between local interface adapters 58 and
`50 of the headset 14 and the mobile telephone 12, respectively. Session contro] may also occur between WLAN
`interface adapters 60 and 52 ofthe headset and the mobile telephone 12, respectively. Steps 252 through 268
`are generally repeated whenever a new sessionis started. The exemplary method 250 utilizes WLANinterface
`adapters 52 and 60 to stream audio from the server 102 to the headset 14.
