  • Publication number: 20120113895
    Abstract: A system and method for providing an indication of a priority level of a non access stratum (NAS) message. In one aspect, a wireless communication device transmits a NAS signaling message together with a Packet Flow Identifier (PFI) information element that includes information indicating a priority level of the NAS signaling message. If the NAS signaling message has a low priority, the wireless communication device may receive a response message indicating that the ongoing NAS signaling message scenario can be performed less frequently in the future, thereby mitigating network congestion and radio interference.

  • Publication number: 20120093008
    Abstract: A wireless communication network having received-priority access requests on an access channel issues an implicit reject response on a grant channel, such as a flag or other value embedded in an explicit access grant or explicit access reject response. The implicit reject response applies to some or all outstanding low-priority access requests. At the expiration of a terminal's grant channel monitoring window, if it has detected an applicable implicit reject response but not an explicit response, the terminal will refrain from transmitting another access request for a predetermined or configurable duration. The implicit reject response may comprise a flag, or a value that implicitly rejects only a fraction of the outstanding low-priority access requests. The implicit reject response may comprise a duration that the terminal must wait prior to transmitting another access request, and may direct the terminal to directly monitor the grant channel without transmitting a subsequent access request.

  • Publication number: 20120046037
    Abstract: User Equipment (UE) receiving non-voice packet switched services in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a voice service page. An eNodeB of the active eUTRAN cell uses a measurement report history for the UE to select an available circuit switched cell for handover. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell. A Gs-like interface between a Mobile Switching Center (MSC) of the CS Core Network and the Mobility Management Entity (MME) of the Evolved Packet Core provides an interface for page requests and location update procedures to be performed.

  • Publication number: 20120040643
    Abstract: Techniques for selectively barring access attempts based on network resource identifiers for serving core network nodes are described. In an example method, an access terminal determines whether access barring based on serving node identifiers is applicable to the access terminal. If so, the access terminal compares a broadcasted serving node identifier to an identifier for the serving core network node, and selectively suppresses access activity by the access terminal based on the comparison, e.g., if the serving core network node for the access terminal matches a broadcast node identifier.

  • Publication number: 20110317636
    Abstract: To access a network, an MTC device sends a channel request message to the network over a random access channel. The channel request message includes a device type indication and a resource type indication. The device type indication may for example, indicate to the network that the requesting device is an MTC device or non-MTC device. Upon receipt of the channel request, the receiving network node can determine on the basis of the device type indication and resource type indication whether to grant or deny the access attempt, and to determine what resources to grant. The channel request message may further include a call duration indication in the channel request message if CS resources are requested for a voice call or a priority indication if CS resources are requested for a data transmission.

  • Publication number: 20110274058
    Abstract: Embodiments herein advantageously reduce the amount of control signalling and header information that must accompany an application layer message when transporting that message from a wireless device to a supporting application server via an intermediate node. To do so, the wireless device prepares a single radio block that includes the application layer message and an indication that the single radio block contains the entire application layer message. The device then sends a control message to the intermediate node that requests allocation of radio resources for sending the single radio block without establishing a temporary block flow (TBF). The device finally sends the single radio block using the allocated resources, without a TBF. Upon receiving the block, the intermediate node determines, based on the indication within the block, whether or not the block contains an entire application layer message. If so, the intermediate node forwards that application layer message towards the application server.

  • Publication number: 20110250862
    Abstract: The transmission of a warning message to a mobile terminal in a mobile communication network is triggered by an emergency event. The mobile terminal is first made aware of the need to receive a warning message by reception of an emergency event notification. The warning message is divided into a plurality of message segments. Each segment is transmitted in a separate paging message over a paging channel to mobile terminals in an idle mode. Information is added to each message segment to enable the mobile terminal to discriminate between segments belonging to different warning messages.

  • Publication number: 20110235581
    Abstract: When a wireless terminal attaches to the network, the wireless terminal is assigned a temporary identifier. Different sets of access restrictions are associated with different blocks of temporary identifiers. When a message and a corresponding temporary identifier is received by the network from a requesting wireless terminal, an access controller identifies the block to which the assigned temporary identifier belongs and determines the access restrictions associated with that block.

  • Publication number: 20100110946
    Abstract: A method of transmitting a downlink, coding scheme CS-1 RLC/MAC control message from a BSS to an EGPRS MS (61), and receiving and detecting the CS-1 RLC/MAC control message in the MS. The BSS places in an MCS-1 radio block, a CS-1 RLC/MAC control block identical to a coding scheme CS-1 RLC/MAC control message excluding the MAC header octet. The BSS also places a coding scheme CS-4 stealing bit code word in the radio block using legacy stealing bit values and positions. The CPS field (26) of the block header (25) indicates that the radio block contains a CS-1 RLC/MAC control message. The MS receives the radio block and detects the coding scheme CS-4 stealing bit code word. In response, the MS interprets the received radio block header to identify the CPS field. The MS determines from the CPS field that a CS-1 RLC/MAC control block has been received.

  • Publication number: 20100080125
    Abstract: The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.

  • Publication number: 20100040008
    Abstract: Two User Equipment (UE) operate in a Near Companion Mode (NCM), in which a monitoring UE (MUE) monitors an uplink transmission opportunity granted to its companion UE (CUE) on a shared uplink channel. If the CUE does not begin transmitting within a predetermined portion of its transmission opportunity, the MUE may utilize the transmission opportunity to transmit an uplink data packet. In one embodiment, where the CUE does not have data to transmit, it may transmit a predetermined pattern at the beginning of its transmission opportunity, to indicate to the MUE that the transmission opportunity is available. The MUE may transmit an NCM radio block using the entire symbol space associated with the last three of four bursts allocated to the CUE, or using a newly defined NCM format comprising four abbreviated bursts, using only a portion of the symbol space associated with the four bursts corresponding to the transmission opportunity allocated to the CUE.
