摘要:
A method for supporting rescue channels in a communications system. The rescue channel feature supports the use of pre-allocated radio resources at neighboring BSs 104, 106 in order to attempt to recover a voice call in danger of being dropped. The MS 114 disables its transmitter upon detection of a loss of forward frames from the network. Once the source BS 102 detects a loss of transmission from the MS 114, it may attempt to re-establish communication with the MS 114 by performing soft handoff additions to rescue cells at neighboring BSs. The neighboring BSs are the MS's neighbor list, last reported Extended Pilot Strength Measurement Message (EPSMM), and possibly other factors.

To address the need to support multiple packet data service instances in a more efficient manner, various signaling enhancements are provided. These enhancements will result in faster packet data call setups, reactivations, and dormant handoffs of multiple service instances while reducing over-the-air signalling. For originations of multiple packet data service connections, the mobile (101) requests the setup of up to six service instances with a single origination message (e.g., 400). For packet data dormant handoffs, the mobile requests the handoff of up to six service instances using a single message. And for reactivations, the mobile requests the reconnection of multiple, dormant packet data service instances with a single message.

Various embodiments are described herein to address the need for reducing call setup delays with respect to supplemental channels. Modifications to channel assignment messaging (104), such as an enhanced ECAM, and service connection messaging (108), such as an enhanced SCM, are described. These modifications enable the assignment of SCHs (110) earlier in the call setup sequence. In addition, embodiments for determining and anticipating when such modified messaging may effectively speed the transfer of data (including VoIP) between a BS (201) and an MS (210) are described.

A method and apparatus for broadcast services transmission and reception. Reception of a broadcast multicast transmission is requested. Preliminary short time updated key information is transmitted or received prior to transmitting or receiving a broadcast subscription key for the requested broadcast services transmission. An encrypted broadcast services transmission is transmitted or received. The encrypted broadcast services transmission is encrypted or decrypted using the preliminary short time updated key information.

The need to reduce the cost associated with signaling mobiles (120) across multiple cells (101–108) is addressed by embodiments of the present invention. A targeted MS is initially paged only in those cells in which the paging channel loading level is below a particular paging threshold. Similarly for short messaging, the RAN transmits the short messaging to the MS only in those cells in which the paging channel loading level is below a short messaging threshold. Therefore, the MS can be signaled in under-loaded cells first, were the effect on system capacity and performance is negligible. When successful, the MS signaling is achieved at a lower cost to the system than when loaded cells are involved.
摘要:
A communication device [400] includes a transceiver [405] to receive and transmit data. A message detection element [410] detects at least a first message and a second message in the data received by the transceiver [405]. A processor [400] modifies a state of the communication device [400] based on the first message and the second message. A positive acknowledgement is transmitted in response to the first message comprising a call pending message, and the state is modified to establish a session and inhibit an alerting of a user of the communication device. The state is modified to alert the user of the communication device [400] in response to the second message comprising a call start message.

The present invention provides a system and method for communication based on an availability level of a presence entity in a communication network that includes a first step (400) of configuring at least one privacy rule for a communication service, wherein the at least one privacy rule is associated with the presence entity and assigns a potential caller to a prioritized group. A next step (402) includes receiving an indication of availability of the presence entity. A next step (404) includes controlling communication access with the presence entity based on the at least one privacy rule, wherein communication access between the presence entity and the caller is controlled by the priority for that caller and the availability indication of the presence entity.
摘要:
A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.
摘要:
A user initiates a group call from an initiating communication device to a plurality of group call recipients' communication devices. Then, a processor circuit determines a wait time for commencing communication of the group call according to a predetermined function. The predetermined function is based least in part on status information for at least a portion of the group call recipients wherein the status information includes a likelihood of participation in the group call. The status information used as part of the predetermined function may include various factors relevant to the likelihood of or expecting timing of a group call recipient's joining the call. Perceived delays can be further reduced by storing group call media prior to sending the media to or playing the media at a particular group call recipients' communication devices.

A system (100) and method (200) is provided to customize services (150). The method can include conveying (204) access network information from a user device to a core network using a SIP message, and adapting (206) a service provided by the core network according to the access network information contained in the SIP message. The method can include creating a header field to convey the access network information. A roaming status indictor can be included in a SIP SUBSCRIBE, a SIP INVITE, a SIP MESSAGE or a SIP REGISTER for adapting the delivery of presence state information concerning a resource.
