Referring now to FIG. 1, a wireless communication system 100 is disclosed in accordance with various embodiments presented herein. The system 100 includes a base station 102 that may include multiple antenna groups. For example, one antenna group may include antennas 104 and 106, another group may include antennas 108 and 110, and an additional group may include antennas 112 and 114. It may include. Two antennas are disclosed for each antenna group; However, more or fewer antennas may be used for each group. The base station 102 may further include a transmitter chain and a receiver chain, each of which may eventually be associated with a number of components (e.g., associated with signal transmission and reception, as will be appreciated by those skilled in the art). For example, processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.).

Base station 102 may communicate with one or more mobile devices, such as mobile device 116 and mobile device 122; However, it should be appreciated that base station 102 may communicate with substantially any number of mobile devices similar to mobile devices 116 and 122. Mobile devices 116 and 122 are, for example, cellular telephones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs and And / or any other suitable device for communicating via wireless communication system 100. As disclosed, mobile device 116 communicates with antennas 112 and 114, where antennas 112 and 114 transmit information to mobile device 116 over forward link 118, and reverse Receive information from mobile device 116 via link 120. In addition, mobile device 122 communicates with antennas 104 and 106, where antennas 104 and 106 transmit information to mobile device 122 via forward link 124 and reverse link ( Information is received from the mobile device 122 via 126.

Frequency bands different from those used may be used. In addition, in a time division duplex (TDD) system, the forward link 118 and the reverse link 120 may use a common frequency band, and the forward link 124 and the reverse link 126 may use a common frequency band. .

Each group of antennas and / or the area in which the antennas are designated to communicate may be referred to as a sector of base station 102. For example, antenna groups may be designed to communicate with mobile devices in a sector of the area covered by base station 102. In communications over the forward links 118 and 124, the transmit antennas of the base station 102 are used to improve the signal-to-noise ratio of the forward links 118 and 124 to the mobile devices 116 and 122, Beamforming may be used. In addition, the base station 102 uses beamforming to transmit to randomly distributed mobile devices 116 and 122 over the associated coverage, while mobile devices in neighboring cells are connected to all their mobile devices through a single antenna. It may be less coherent compared to the transmitting base station. In addition, mobile devices 116 and 122 can communicate directly with each other using peer-to-peer or ad hoc techniques, as disclosed.

According to one embodiment, system 100 may be a multiple-input multiple-output (MIMO) communication system. In addition, the system 100 may use substantially any type of duplexing technique for splitting communication channels (eg, forward link, reverse link, ...), such as FDD, TDD, and the like. The communication channels may comprise one or more logical channels in one embodiment. Mobile devices 116 and 122 connecting to base station 102 may use a connection request to request communication channels and / or additional resources (eg, move within, and out of range of base station 102). Can be switched from an idle state to an active state). This may be performed at the radio resource control (RRC) layer of the mobile devices 116 and 122 which handle the establishment, reconfiguration and release of radio bearers in the signaling plane. When a connection is established, signal data transmission can occur. In other embodiments, a single-stage connection may be sufficient to initiate user plane data transmission.

However, in some cases, it may be desirable to send additional information with the connection request, such as non-access stratum (NAS) messages, re-authentication information, and / or additional parameters. Similarly, a single transmission time interval (TTI) assigned for the signaling connection setup disclosed above may not allow enough time to transmit the desired parameters. Thus, a multi-step connection procedure may be selected in which the initial connection request message may be sent from the mobile device 116 and / or 122 to the base station 102, and subsequently the mobile device 116 in which the additional message includes additional information. And / or 122 to base station 102. After the information has been transmitted, the base station 102 can transmit a connection setup confirmation to the mobile device 116 and / or 122 to allow subsequent user plane data transmission.

In one embodiment, base station 102 may transmit connection requests to one or more separate network components (not shown) based on the request from mobile device 116 and / or 122. For example, a mobility management entity (MME) that manages and stores a UE context, which may include identities, mobility data, other security parameters, and / or the like. ), Or similar components. In one embodiment, the MME may send an early downlink message to send verification back to base station 102 and / or to send to mobile devices 116 and / or 122, which is Allow mobile device 116 and / or 122 and / or base station 102 to send additional data (such as re-authentication parameters and / or other parameters that may be present in the NAS message). Subsequently, mobile device 116 and / or 122 and / or base station 102 may transmit additional information and receive a connection setup message allowing subsequent user data transmission.

2, a communication device 200 for use within a wireless communication environment is shown. Communication device 200 may be a base station or a portion of a base station, a mobile device or a portion of a mobile device, or substantially any communication device that receives and / or transmits data transmitted in a wireless communication environment. The communication device 200 may additionally transmit parameters in a connection setup such as an initial connection message generator 202 capable of generating an initial connection message such as an RRC message, a NAS message, a re-authentication message, and / or the like. Messages generator 204 capable of generating messages or messages, and transmitter 206 capable of broadcasting disparate messages to one or more access points.

In one embodiment, the communication device 200 may attempt to connect with one or more access points for transmitting communication data. The communication device 200 may use the transmitter 206 to transmit preamble communication to one or more access points. This may result in receiving an initial uplink access authorization with the access point. The initial connection message generator 202 may then be used to generate a connection establishment request, such as an RRC message, for example, to obtain radio resources at the RRC layer. The initial connection message may be sent to the access point using the transmitter 206. However, in some cases, the size of the original message may be limited in a wireless communication configuration, such as an RRC message, which may be limited to a single TTI. Thus, additional information may be requested and / or requested.

In this case, the communication device 200 establishes a multi-level connection by using the additional message generator 204 to generate a message containing additional parameters or other data for transmission to the access point or another component for communication therewith. Can be used. In one embodiment, further message generation (or transmission by transmitter 206) indicates, for example, that an initial connection message was received, sent to a network component (not shown), received a response from the network component, and the like. It should be appreciated that this may occur based on receiving an early downlink message from the access point. The downlink message may also include resources for transmitting the further message, for example. In one embodiment, the additional message may comprise a NAS message, which allows communication between the communication device 200 and the network component, is required for transmission by the communication device 200, or is downstream network component. Can be required by The NAS message may in one embodiment be a service request message, a tracking area update request message, a message used to verify or transmit the communication device 200 or user / UE context, identification, authentication information, and / or the like. It may be others.

Further messages may be used to facilitate re-authentication and / or re-configuration of security between communication device 200 and network components; In one embodiment, an access point may be used to facilitate communication between the component and the device 200. For example, the network may require re-authentication and / or reconfiguration for a number of reasons including termination of session time, termination of connection, state change, handover to different base stations, and the like. In this regard, the additional message generator 204 can be used to generate the required or requested security / re-authentication information, which information is sent by the transmitter 206 (eg, via an access point) to a network component. Can be sent to. In another configuration, additional messages may be used to re-synchronize the UE or communication device 200 context, for example, a network and / or context describing different information about the UE or communication device 200. Requires a communication session associated with the.

The communication device 200 may select a single or multi-level connection setup according to various factors, including received additional communication requests, inferences about information required by one or more network components of the wireless communication network, and / or the like. Be aware that you can. For example, before communication is established, a message may be sent to communication device 200 requesting one or more additional messages (eg, via an access point) from a network component. This may occur, for example, following the initial connection message transmission. Depending on whether the communication device 200 selects a single-stage or multistage connection setup, user plane data transmission may result (eg, from a network component) subsequent to the connection setup state.

Referring now to FIG. 3, a wireless communication system 300 is disclosed that can utilize a single-stage or multi-stage selectable communication connection setup. System 300 includes a base station 302 that can communicate with mobile device 304 (and / or any number of different mobile devices (not shown)) to facilitate a wireless communication service. Base station 302 may transmit information to mobile device 304 over a forward link channel; In addition, the base station 302 can receive information from the mobile device 304 over a reverse link or uplink channel. In addition, the base station 302 transmits data to and transmits data from the core network component 306 to facilitate communication with and provide services to the mobile device 304. Can be received. In one embodiment, the core network component 306 may be an MME. In addition, the system 300 may be a MIMO system. In addition, system 300 may operate in an OFDMA wireless network (eg, such as GPP, 3GPP LTE, and the like). Furthermore, in one embodiment, the components and functions shown and described below at base station 302 may be displayed on mobile device 304 likewise and vice versa; The disclosed configuration may exclude these components to facilitate description.

The base station 302 uses the core network component 306 to request a connection requestor 308 that can request connection establishment for the mobile device 304, and additional information or parameters for additional connection establishment from the mobile device 304. An additional message requester 310 that can request, and a connection state specifier 312 that can return a status of establishing a connection to the mobile device 304. In one embodiment, the connection requester 308 may request information about the mobile device 304 from the core network component 306 in response to a connection establishment request from the mobile device 304. If additional information is required to establish a connection, the additional message requestor 310 may, for example, request information or prompt the mobile device 304 to send the information. The connection state specifier 312 may transmit a connection state to the mobile device 304, for example, when connection establishment is complete, a timeout occurs, or the like.

Mobile device 304 may send an initial message generator 314 that generates a connection establishment message, such as an RRC message, an additional connection related parameter (such as security, context, identity parameters, and the like). Message generator 316, and a connection step selector 318 that can select single-step or multi-step connection settings based at least in part on the need to send additional information with the connection establishment request. For example, upon request for establishing communication with a base station 302 (eg, as a result of a state change, such as from active to idle), the original message generator 314 may be size limited (eg, one With the above TTIs), a connection establishment message, such as an RRC message, may be generated and the message may be transmitted to the base station 302. If additional information is required or requested, the connection step selector 318 may be tailored for a multi-stage connection setup, and the additional message generator 316 may generate a message with additional parameters for sending additional messages to the base station. In one embodiment, it should be appreciated that this may be performed based on a request from the base station 302 for additional data.

According to one embodiment, mobile device 304 may use initial message generator 314 to generate and send an initial access message to base station 302. In this regard, the mobile device 304 may attempt to establish a connection with the base station 302. Base station 302 uses core network component 306 to initiate, authenticate, and / or provide media-level (eg, RRC layer) communication resources to connect mobile device 304. ) Can be used. The base station 302 can transmit information about the mobile device 304 via core network component 306 communication. For example, the base station 302 can transmit the identity, context, security parameters, and / or the like about the mobile device 304 to the core network component 306. If the transmitted information is sufficient for the base station 302 and / or the core network component 306, and / or if the connection step selector has selected a single-stage connection setup, the connection state specifier 308 determines the state of the connection. Return to mobile device 304. In one embodiment, this may be based at least in part on information received from the core network component 306.

According to one embodiment, the core network component 306 may request additional information from the mobile device 304 prior to authorizing the connection setup, or the mobile device 304 may request a service request or service request message, tracking area. You may want to send additional information, such as an update request message. This may be the result of a lack of allowed transmission size for the initial connection message. Thus, the core network component 306 can send the request back to the base station, which can use the additional message requester 310 to notify the mobile device 304 of the additional information request. The request may be explicit or may simply be an indicator, a Boolean variable, and / or the like. If the mobile device 304 wishes to send additional information, the mobile device may piggyback the additional information (as in a NAS message) via a connection setup request. In addition, the base station 302 can transmit a downlink message that includes scheduling resources for the mobile device 304 used to transmit additional information. For example, connection step selector 318 can specify a multi-level connection setup based at least in part on one or more of those disclosed above. Once multiple steps are selected, the additional message generator 316 may generate a message containing additional information for transmission to the base station 302.

In one embodiment, the additional information may be in the form of a NAS message that may be sent to the core network component 306 via the base station 302. The message may relate to re-authenticating or re-configuring security for mobile device 304, eg, mobile device 304 context resynchronization and / or the like, as described above. have. In one embodiment, core network component 306 may re-authenticate mobile device 304 moving from an idle state to an active state; Such re-authentication may be required, for example, prior to requiring refreshing of user plane data transmissions, etc., if the security context has expired, and may be requested via additional message requestor 310 as disclosed. have. In another embodiment, the core network component 306 may omit the context for the mobile device 304 and request the context from the base station 302. In this embodiment, the base station 302 can use the additional message requestor 310 to send a request for context to the mobile device 304, and the context can be transmitted as an additional message as previously disclosed. .

In view of the above embodiments, the single-stage connection setup may provide communication connections and resources between the mobile device 304 and the base station 302, where the initial information is all information requested and / or requested. However, connection step selector 318 may select a multi-level connection setup that requires additional information from base station 302, mobile device 304, and / or core network component 306. In either case, a single-step may be used to initialize radio bearers for signaling between mobile device 304 and base station 302. In a multistage connection setup, additional information may be used to initialize user plane radio bearers. Once set, user plane data transmission can occur.

Referring now to FIG. 4, an exemplary wireless communication network 400 for establishing a connection is disclosed. The UE 402 is shown attempting to connect to the eNB 404. The eNB 404 uses the core network MME 406 to collect and use information and / or to authenticate a UE or a user of a UE. As disclosed above, the MME 406 may be used to authenticate a UE / user and may maintain a context to allow for quick connection setup. In this embodiment, the UE 402 can transmit an access preamble to the eNB 406. This may be a request to obtain some uplink resource (s) to facilitate sending additional data for connection establishment. The eNB 404 may send an uplink access authorization to the UE 402 as shown, for example, if the eNB has sufficient available resources. The UE 402 may generate an initial connection message, such as an RRC connection setup message, as shown, and send a message to the eNB 404 using authorized resources. Upon receiving the message, the eNB 404 may send a connection request to the MME 406 with respect to the UE 402. It should be appreciated that the eNB 404 may include substantially any information about the UE 402 in the request to the MME 406.

The MME 406 may, in one embodiment, analyze the UE 402 information (eg, to verify security context, etc.) and optionally select a NAS message to be sent to the UE 402 via the eNB 404. It may indicate that additional information (such as additional security context information, authentication initialization, etc.) is required to establish a connection. In addition, the NAS message may optionally be piggybacked and sent in an RRC Connection Setup-1 message that may be used to notify UE 402 of additionally requested parameters. In addition, the RRC Connection Setup-1 message may provide scheduled media access control (MAC) resources for wireless signaling. These messages are not required; However, using this configuration may allow the eNB 404 to know that additional signaling or parameters are requested, and may transmit information to the UE 402 without setting up additional resources for the UE 402. You will notice.

Subsequent to initial radio signaling resource setup, if additional information or signaling is required, the UE 402 may use signaling radio bearers to transmit information to the MME 406 via the eNB 404; For example, this can be accomplished using NAS messages. In one embodiment, the UE 402 may transmit a buffer status for signaling radio bearers, such that the eNB 404 does not allocate unnecessary resources to the UE 402. The additional information transmitted may be one or more of additional security or authentication parameters, re-authentication parameters, parameters related to the UE 402 context, such as identity, and / or the like. In another embodiment, the signaling may be re-authentication commands sent using additional resources received from an early downlink message that places the UE 402 in normal data scheduling mode. Following the second step of the illustrated authentication procedure, where the information sent using signaling radio bearers is requested, the MME 406 may transmit a connection setup message for the UE 402 to the eNB 404. The eNB 404 may set additional resources for the UE 402 and send an RRC Connection Setup-2 message to establish a connection. Subsequently, user data transmission may occur between the UE 402 and the MME 406.

In another embodiment, the UE 402 may receive an early downlink message following the initial RRC connection setup message to place the UE 402 in a normal data scheduling mode (not shown); The UE 402 may then send information directly to the MME 406 using the resources allocated in the downlink message from the eNB 404 in place of the signaling. This may be the case, for example, if desired to transmit more information than can be sent in the original RRC connection setup message (eg due to size limitation) without a request from the MME 406. In one embodiment, this may include a NAS message, such as a service request message or tracking area update request message. The information may be transmitted before user data transmission occurs, but may not require additional NAS message, RRC connection setup-1 message, or signaling shown as optional communications, and thus these messages subsequent to the connection request. Can happen instead. Alternatively, additional information, or portions thereof, may be piggybacked and sent in the RRC Connection Setup message. In one embodiment, the eNB 404 may detect that the UE 402 piggybacked and sent a NAS message in an RRC Connection Setup message, and from the MME 406 before transmitting the RRC Connection Setup-1 message. Wait for the NAS message to be sent. If there is no NAS message piggybacked and sent in the RRC Connection Setup message, the eNB 404 may send an RRC Connection Setup-1 message to the UE 402 as soon as the resources are set up. In accordance with the above embodiments, a multi-step connection establishment procedure may be used.

The request may include information about the requestor and may be made at one or more network layers, such as the RRC layer. In this regard, the initial communication may establish the resources needed for communicating additional data. At 504, a determination is made whether a multi-stage connection setup is selected. In one embodiment, the initial communication establishment request may be sufficient to establish communications; However, in other embodiments, more information may be requested. For example, a multi-step selection may be made to accommodate the request for sending additional information, such as an initial communication establishment request being too small or a downstream network component requesting additional information as previously disclosed.

At 506, a multi-level connection setup is selected (e.g., because additional information or parameters are requested / required), and additional parameters are created in association with the request for communication setup. For example, as mentioned above, the parameters may be associated with re-authentication with respect to the network, re-synchronization of context, reconfiguration of security parameters, identity provision, and / or the like. In one embodiment, the allowed initial communication establishment request size may be insufficient to transmit additional parameters; Thus, multilevel is selected and the parameters are transmitted at 508. Subsequently, a connection may be established and user plane data transmission may begin at 510. Also, if the single-step disclosed above is insufficient and multiple steps are not selected at 504, user plane data transmission as well as 510 may begin at this point.

Referring now to FIG. 6, a method 600 is disclosed that facilitates supporting multistage connection setup. At 602, a connection establishment request may be received. The request may include information about the requester to obtain communication resources (eg, wireless signaling bearers) for the requester. At 604, the request is initiated over the network; For example, the downstream network device may have a context for the requestor or other information related thereto. At 606, a determination may be made as to whether additional parameters are required or requested to complete the connection setup. For example, the downstream network may request additional information related to security reconfiguration / authentication, the requestor's identity or context, additional requestor related parameters, and / or the like, as described previously. . At 608, a request for additional parameters may be sent if necessary, and a determination of additional parameters may be made again at 606, and subsequent steps are made in the same manner. If the information and additional parameters given in the request are sufficient at 606, the connection establishment request may be completed at 610 (eg, successfully or otherwise).

In accordance with one or more aspects disclosed herein, inferences may be made in connection with selecting a single-stage or multistage connection setup, as disclosed. As used herein, the terms "infer" or "inference" generally refer to the state of the system, environment, and / or user from a set of observations that are captured through events and / or data.
