The expression “machine-readable medium” may include, without limitation, various other media that can store, store, and / or carry radio channels and instructions and / or data. .

  Now referring to FIG. 1, illustrated is a wireless communication system 100 in accordance with various embodiments presented herein. System 100 comprises a base station 102 that can include multiple antenna groups. For example, one antenna group can include antennas 104 and 106, another group can include antennas 108 and 110, and an additional group can include antennas 112 and 114. . Two antennas are shown for each antenna group. However, more or fewer antennas can be utilized for each group. As will be clearly understood by those skilled in the art, the base station 102 may further include a transmitter chain and a receiver chain, each of which includes a plurality of components (eg, , Processor, modulator, multiplexer, demodulator, demultiplexer, antenna, etc.).

  Base station 102 can communicate with one or more mobile devices such as mobile device 116 and mobile device 122; However, it should be clearly understood that base station 102 can communicate with virtually any number of mobile devices similar to mobile devices 116 and 122. Mobile devices 116 and 122 may be, for example, mobile phones, smartphones, laptops, handheld communication devices, handheld computing devices, satellite radio, global positioning systems, PDAs, and / or other suitable for communicating through the wireless communication system 100. Device. As depicted, mobile device 116 communicates with antennas 112 and 114 that transmit information to mobile device 116 over forward link 118 and receive information from mobile device 116 over reverse link 120. To do. Further, mobile device 122 communicates with antennas 104 and 106, and antennas 104 and 106 transmit information to mobile device 122 over forward link 124 and receive information from mobile device 122 over reverse link 126. In a frequency division duplex (FDD) system, the forward link 118 can utilize a different frequency band than that used by the reverse link 120, and the forward link 124 is employed by the reverse link 126, for example. Different frequency bands can be employed. Further, in a time division duplex (TDD) system, the forward link 118 and the reverse link 120 can utilize a common frequency band, and the forward link 124 and the reverse link 126 have a common frequency band. Can be used.

  Each antenna group and / or the area in which these antennas are designated to communicate may be referred to as a sector of base station 102. For example, antenna groups can be designed to communicate to mobile devices in a sector of the area covered by base station 102. For communication on the forward links 118 and 124, the transmit antenna of the base station 102 can utilize beamforming to improve the signal-to-noise ratio of the forward links 118 and 124 for the mobile devices 116 and 122. In addition, base station 102 utilizes beamforming to transmit to mobile devices 116 and 122 that are randomly scattered throughout the associated coverage, while mobile devices in neighboring cells are all mobile through a single antenna. It can be subject to less interference compared to the base station transmitting to the device. Further, mobile devices 116 and 122 can communicate directly with other mobile devices using peer-to-peer or ad hoc techniques as depicted.

  According to an example, system 100 can be a multiple-input multiple-output (MIMO) communication system. Furthermore, the system 100 can utilize virtually any type of duplexing technique, eg, FDD, TDD, etc., to split a communication channel (eg, forward link, reverse link, etc.). A communication channel may comprise one or more logical channels in one example. The mobile devices 116 and 122 use the connection request to request a communication channel and / or additional resources (eg, by moving within range of the base station in order to transmit resources, etc.) from an idle state to an active state Can be connected to the base station 102. This can be done at the radio resource control (RRC) layer of the mobile devices 116 and 122 that handles radio bearer establishment, reconfiguration, and release in the signaling plane. When the connection is established, signal data transfer can occur. In other examples, a single phase connection may be sufficient to initiate user plane data transfer.

  However, in some cases it may be desirable to send additional information along with the connection request, such as non-access layer (NAS) messages, reauthorization information, and / or additional parameters. Similarly, a single transmission time interval (TTI) assigned for the signaling connection setup described above may not be given enough time to transmit the desired parameters. Accordingly, an initial connection request message can be transmitted from the mobile device 116 and / or 122 to the base station 102, followed by an additional message comprising additional information from the mobile device 116 and / or 122 to the base station 102. A multi-step connection procedure can be selected. After the information is transmitted, the base station 102 can transmit a connection setup confirmation to the mobile device 116 and / or 122 that allows subsequent user plane data transfer.

  In one example, base station 102 can transmit a connection request to one or more disparate network components (not shown) based on requests from mobile devices 116 and / or 122. For example, the request can be sent to a mobility management entity (MME) or similar component that manages and stores the UE context, which can include identity, mobility data, other security parameters, and the like. The MME, in one example, transmits an initial downlink message to be transmitted back to the base station 102 and / or transmitted to the mobile device 116 and / or 122 so that the mobile device 116 and / or 122 and / or the base station 102 Additional data (e.g., reauthorization parameters and / or other parameters that can be included in the NAS message) can be allowed to be transmitted. Subsequently, the mobile device 116 and / or 122 and / or the base station 102 can receive a connection setup message that allows additional information to be transmitted and subsequent user data transfer.

  With reference to FIG. 2, illustrated is a communications apparatus 200 for use in a wireless communications environment. Communication device 200 can be a base station or a portion thereof, a mobile device or a portion thereof, or virtually any communication device that transmits and / or receives transmitted data in a wireless communication environment. The communication device 200 includes an initial connection message generator 202 that can generate an initial connection message, eg, an RRC message, and additional parameters or messages to be transmitted in connection establishment, eg, a NAS message, a reauthorization message, , Etc., and a transmitter 206 that can broadcast these disparate messages to one or more access points.

  In one example, the communication device 200 may be attempting to connect with one or more access points to transmit communication data. The communication apparatus 200 can transmit preamble communication to one or more access points using the transmitter 206. As a result, the initial uplink access permission for the access point can be received. Thus, using the initial connection message generator 202, it is possible to generate a connection establishment request, for example, an RRC message, for acquiring radio resources in the RRC layer, for example. The initial connection message can be transmitted to the access point using the transmitter 206. However, in some cases, the size of the initial message can be limited in a wireless communication configuration, such as an RRC message that can be limited to a single TTI, and so on. Thus, additional information can be desired and / or requested.

  In this case, the communication device 200 uses the additional message generator 204 to establish a multi-step connection by generating a message comprising additional parameters or other data to be transmitted to the communicating access point or other component. Can be used. In one example, additional message generation (or transmission by transmitter 206) received, for example, an initial connection message was received, sent to a network component (not shown), or received a response from the network component. It should be clearly understood that this can occur based on receiving an initial downlink message from the access point indicating that, etc. The downlink message may also comprise a resource for sending additional messages, for example. The add message may comprise a NAS message in one example, which may enable communication between the communication device 200 and the network component and may be desired by the communication device 200 for transmission or In one example, it can be requested by a downstream network component. The NAS message may be, for example, 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, authorization information, and so on. .

  Further, the additional message can be utilized to facilitate reauthorization and / or security reconfiguration between the communication device 200 and the network component, and in one example, the access point can It can be used to facilitate communication with the device 200. For example, the network may require re-authorization and / or security reconfiguration for several reasons including session time expiration, connection loss, state change, handover to disparate base station, and so on. In this regard, additional message generator 204 can be utilized to generate requested / required security / reauthorization information, and that information is transmitted by transmitter 206 (eg, via an access point) to network configuration. Can be sent to the element. In other configurations, for example, if the network requires context representing different information about the UE or the communication device 200 and / or the communication session associated therewith, the context of the UE or communication device 200 can be changed using an additional message. You can resynchronize.

  The communication device 200 can be single phase or multi-phase depending on various factors including received additional communication requests, inferences made about information required by one or more network components of the wireless communication network, etc. It should be clearly understood that connection establishment can be selected. For example, a message can be communicated from a network component (eg, through an access point) to a communication device 200 that requests one or more additional messages before communication can be established. This can occur, for example, following the initial connection message transmission. Regardless of whether the communication device 200 selects single phase or multi-phase connection establishment, the result can be user plane data transfer according to the connection setup state (eg, from a network component).

  Now referring to FIG. 3, illustrated is a wireless communication system 300 that can utilize single-step or multi-step selectable communication connection establishment. System 300 includes a base station 302 that can communicate with a mobile device 304 (and / or any number of disparate mobile devices (not shown)) to facilitate wireless communication services. Base station 302 can transmit information to mobile device 304 over a forward link channel, and base station 302 can receive information from mobile device 304 over a reverse link or uplink channel. Further, base station 302 can transmit data to and receive data from core network component 306 to facilitate communicating with and providing services to mobile device 304. it can. In one example, the core network component 306 can be an MME. Further, system 300 can be a MIMO system. Further, system 300 can operate in an OFDMA wireless network (eg, 3GPP, 3GPP LTE, etc.). Further, the components and functions within the base station 302 shown and described below may also exist in the mobile device 304 in one example and vice versa, and the depicted configuration is easy to explain. These components are excluded for the purpose of

  The base station 302 requests a connection requester 308 that can request a connection establishment for the mobile device 304 using the core network component 306 and additional information or parameters from the mobile device 304 to facilitate the connection establishment. And an additional message requester 310 that can send back a connection establishment status to the mobile device 304. In one example, the connection requester 308 can 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 requester 310 can prompt the mobile device 304 to request information or send information, for example. The connection state designator 312 can transmit the connection state to the mobile device 304 when, for example, the connection establishment is completed or a time-out occurs.

  The mobile device 304 generates an initial message generator 314 that generates a connection establishment message, eg, an RRC message, and an additional message generator that can send additional connection related parameters (eg, security, context, identity parameters, etc.). And a connection phase selector 318 that can select single phase or multi-phase connection establishment based at least in part on the need to send additional information with the connection establishment request. For example, upon requesting communication establishment with the base station 302 (eg, as a result of a state change from an idle state to an active state), the initial message generator 314 may change the size (eg, to one or more TTIs). A connection establishment message that can be restricted, eg, an RRC message, can be generated and sent to the base station 302. If additional information is desired or required, the connection phase selector 318 can select multi-phase connection establishment, and the additional message generator 316 can provide additional parameters for sending the additional message to the base station. Messages can be generated. It should be clearly understood that this can be done based on an additional data request from the base station 302 in one example.

  According to an example, the mobile device 304 can utilize the initial message generator 314 to generate an initial connection message and send it to the base station 302. In this regard, the mobile device 304 can attempt to establish a connection with the base station 302. The base station 302 utilizes the connection requester 308 to initialize the mobile device 304, authenticate the mobile device 304 with the core network component 306, and / or media level (eg, RRC layer) communication resources. Can be provided. It should be clearly understood that base station 302 can transmit information regarding mobile device 304 having communication with core network component 306. For example, base station 302 can transmit identity, context, security parameters, etc. for mobile device 304 to 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 phase selector has chosen to establish a single phase connection, the connection status specifier 308 The state can be returned to the mobile device 304. This may be based at least in part on information received from the core network component 306 in one example.

  According to an example, the core network component 306 can request additional information from the mobile device 304 before allowing the connection to be established, or the mobile device 304 can receive additional information, eg, a service request or service request message, tracking An area update request message, etc. can be sent. This can be the result of the absence of an allowed transmission size for the initial connection message. Accordingly, the core network component 306 can return the request to the base station, and the base station can notify the mobile device 304 of the additional information request using the additional message requester 310. The request can be explicit or can simply be an indicator, a Boolean variable, etc. If the mobile device 304 desires to send additional information, the additional information can be piggybacked (eg, as in a NAS message). Further, base station 302 can transmit a downlink message comprising scheduling resources for mobile device 304 to transmit additional information. For example, the connection phase selector 318 can specify multi-phase connection establishment based at least in part on one or more of the above. When multiple phases are selected, the additional message generator 316 can generate a message comprising additional information for transmission to the base station 302.

  In one example, the additional information can be in the form of a NAS message that can be transmitted through the base station 302 to the core network component 306. The message can relate to re-authentication or security reconfiguration for the mobile device 304, eg, mobile device 304 context resynchronization as described above. In one example, the core network component 306 can re-authenticate the mobile device 304 when the mobile device 304 transitions from an idle state to an active state, such that the security context has expired, for example. Can be requested before user plane data transfer, and can be requested through the additional message requester 310 as described above. In other examples, the core network component 306 may have lost context for the mobile device 304 and may request that context from the base station 302. In this example, the base station 302 can utilize the add message requester 310 to send a context request to the mobile device 304 and send the context as an add message as described above.

  In view of the above, single phase connection establishment may provide for establishing communication connections and resources between base station 302 and mobile device 304, where initial information is desired and / or All required information. However, the connection phase selector 318 can select multi-phase connection establishment if additional information is desired from the base station 302, mobile device 304, and / or core network component 306. In any case, a single phase can be utilized to initialize a radio bearer for signaling between the mobile device 304 and the base station 302. In multi-phase connection establishment, the additional information can be used to initialize the user plane radio bearer. Once established, user plane data transfer can occur.

  Now referring to FIG. 4, an example wireless communication network 400 for connection establishment is shown. A state in which the UE 402 is attempting to connect to the eNB 404 is shown. The eNB 404 may utilize the core network MME 406 to collect and use information and / or authenticate the UE or its user. As described above, the MME 406 can be used to authenticate the UE / user and can store context to allow for fast connection establishment. In this example, the UE 402 can send an access preamble to the eNB 406. This can be a request to obtain some uplink resources that facilitate transmitting additional data for connection establishment. The eNB 404 may send an uplink access grant to the UE 402 as indicated, for example, if the eNB has sufficient available resources. UE 402 may generate an initial connection message, eg, an RRC connection setup message as shown, and send the message to eNB 404 using authorized resources. Upon receiving the message, the eNB 404 can send a connection request for the UE 402 to the MME 406. It should be clearly understood that the eNB 404 can include virtually any information regarding the UE 402 in the request to the MME 406.

  The MME 406 in one example parses the UE 402 information (eg, to verify the security context) and optionally has additional information (eg, additional security context information, authentication initialization, etc.) to establish a connection. A NAS message to UE 402 may be sent via eNB 404 that may indicate that it is required. Further, the NAS message can optionally be added to the RRC Connection Setup-1 message that can be used to notify the UE 402 of the additionally requested parameters. Further, the RRC Connection Setup-1 message can provide scheduled media access control (MAC) resources for radio signaling. Although these messages are not mandatory, utilizing this configuration may allow the eNB 404 to know that additional signaling or parameters are required, and establish additional resources for the UE 402 It should be clearly understood that information can be sent to the UE 402 without it.

  If additional information or signaling is desired following the initial radio signaling resource establishment, the UE 402 can use the signaling radio bearer to send information to the MME 406 via the eNB 404, eg, This can be achieved using messages. In one example, the UE 402 can send a buffer state for the signaling radio bearer so that the eNB 404 does not allocate unnecessary resources to the UE 402. The additional information sent can be one or more of additional security or authentication parameters, re-authorization parameters, parameters associated with the UE 402 context, eg, identity, etc. In another example, the signaling can be a re-authorization command sent with additional resources received from the initial downlink message that puts the UE 402 into normal data scheduling mode.

Following the second phase of the indicated authentication procedure, the MME 406 may send a connection setup message to the eNB 404 for the UE 402 if the information sent using the signaling radio bearer is as requested. The eNB 404 may establish additional resources for the UE 402 and send an RRC connection setup-2 message to establish a connection. Subsequently, user data transfer can occur between the UE 402 and the MME 406.

  In another example, the UE 402 can receive an initial downlink message following the initial RRC connection setup message to place the UE 402 in a normal data scheduling mode (not shown), Thus, information can be transmitted directly to the MME 406 using resources allocated in the downlink message from the eNB 404 instead of signaling. This is the case, for example, when the UE 402 wishes to send more information than can be sent in the initial RRC connection setup message without necessarily requesting from the MME 406 (eg due to size limitations). Can do. In one example, this may include a NAS message, such as a service request message or a tracking area update request message. Information can be sent before user data transfer can occur, but no additional NAS messages, RRC connection setup-1 messages, or signaling, which are indicated as optional communications, can be requested, so connection requests Can occur instead of these messages. Alternatively, additional information, or a portion thereof, can be added to the RRC connection setup message. In one example, the eNB 404 can detect that the UE 402 is appended to the NAS message to the RRC connection setup message and wait for NAS message transfer from the MME 406 before sending the RRC connection setup-1 message. Can do. When there is no NAS message added to the RRC connection setup-1 message, the eNB 404 can transmit the RRC connection setup-1 message to the UE 402 as soon as resources are established. By the above example, a multi-phase connection establishment procedure can be used.

With reference to FIGS. 5 and 6, illustrated are methods associated with providing selective phase communication establishment in a wireless communication network. For the purpose of simplifying the description, these methods are shown and described as a series of actions, while some actions are shown and described herein according to one or more embodiments. It should be understood and appreciated that these methods are not limited by the order of actions since they can occur in different orders and concurrently with other actions. For example, those skilled in the art will understand and appreciate that a method could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with one or more embodiments.
With reference to FIG. 5, illustrated is a methodology 500 that facilitates establishing a multi-phase connection in a wireless communication network. At 502, an initial communication establishment request can be transmitted. This request can comprise information about the requester and can be made at one or more network layers, eg, the RRC layer. In this regard, initial communication can establish the resources necessary to communicate additional data. At 504, a determination is made as to whether multi-phase connection establishment has been selected. In one example, the initial communication establishment request can be sufficient to establish communication. However, in other examples, more information can be requested. For example, multi-phase selection can be made to address the desire to send additional information when the initial communication establishment request is too small or when the downstream network component requests additional information as described above.

  If multi-phase connection establishment is selected (eg, because additional information or parameters are desired / required), at 506, additional parameters associated with the communication establishment request are generated. For example, as described above, these parameters can relate to network re-authorization, context resynchronization, security parameter reconfiguration, identity provisioning, and the like. In one example, the allowed initial communication establishment request size may be insufficient to send additional parameters, so multiple phases are selected at 508 and parameters are sent. Subsequently, a connection can be established, and at 510, user plane data transfer can begin. Further, if the single phase described above is sufficient, no multi-phase is selected at 504 and user plane data transfer can begin at 510 at this point as well.

  Now referring to FIG. 6, a methodology 600 that facilitates supporting multi-phase connection establishment is illustrated. At 602, a connection establishment request can be received. This request may comprise information about the requester to obtain communication resources (eg, a radio signaling bearer) related to the requester. At 604, the request is initialized for the network. For example, the downstream network device may have context about the requestor or other information associated with it. At 606, a determination can be made regarding whether additional parameters are desired or required to complete the connection establishment. For example, the downstream network may request security reconfiguration / authorization, requester identity or context, additional requester related parameters, etc., as described above. At 608, a request for additional parameters can be sent if desired, and therefore a determination regarding additional parameters can be made at 606. If the information and / or additional parameters provided in the request are sufficient at 606, the connection establishment request can be completed (eg, successfully or otherwise) at 610.

  In accordance with one or more aspects described herein, inferences regarding selecting a single phase or multi-phase connection establishment may be made as described. As used herein, the term “infer” or “inference” generally infers a system, environment, and / or user state from a set of observations obtained via events and / or data. Refers to the process of doing or inferring. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. Inference can be probabilistic, i.e., calculating a probability distribution over the subject state based on data and event considerations. Inference can also refer to techniques employed for assembling higher level events from a set of events and / or data. As a result of the inference, new events or behaviors will be constructed from a set of observed events and / or stored event data, and these events are interrelated in time. Whether or not these events and data are from one or several events and data sources.

  By way of example, one or more of the methods described above may select a connection establishment type (eg, single phase or multi-phase), send additional parameters with a connection establishment request, send additional parameters, send additional parameters Making inferences about protocols or NAS messages, etc.
