Methods and apparatus are described for synchronizing compression for communication between a user equipment (UE) and a serving node. The methods and apparatus include determining that a compressor memory of a compressor and a decompressor memory of a decompressor are out-of-synchronization based on a checksum failure. Further, the methods and apparatus include resetting the compressor memory and the decompressor memory to a predetermined state in response to determining that the compressor memory and the decompressor memory are out-of-synchronization, wherein the compressor memory and the decompressor memory are synchronized at the predetermined state.

Out-of synchronization detection and correction during compression

Methods and apparatus are described for reordering a header of a transmission data packet. The methods and apparatus include identifying one or more static fields and one or more dynamic fields within a header of the transmission data packet. Moreover, these aspects include reordering the one or more static fields and the one or more dynamic fields within the header of the transmission data packet. Additionally, these aspects include compressing the header of the transmission data packet to form a compressed transmission data packet in response to reordering the one or more static fields and the one or more dynamic fields. The aspects also may include transmitting the compressed transmission data packet.

Method and apparatus for efficient packet compression

Methods and apparatus of compression on multiple data flows for communication between a user equipment (UE) and a serving node. The methods and apparatus include receiving multiple data flows for compression, wherein each of the multiple data flows includes a plurality of data packets, with each data packet having a data packet header and a payload. Further, the methods and apparatus include determining a compression state for each of the multiple data flows. Moreover, the methods and apparatus include performing a first compression algorithm on each of the multiple data flows determined to have a compression state set to a do-not-compress state, wherein the first compression algorithm includes compressing the data packet header of each data packet without compressing the payload of each data packet.

Handling incompressible data packets on multiple data flows

Methods and apparatus are described for formatting a compressed data packet. The methods and apparatus include identifying a first data string within a data packet that was previously stored at a first memory location in a compressor memory, and generating a first pointer that references the first memory location in the compressor memory. Further, these aspects optionally include identifying a second data string within the data packet that was not previously stored in the compressor memory. Additionally, these aspects include creating a compressed data packet by replacing the first data string with the first pointer and copying the second data string, and including an indicator corresponding to a number of pointers in the data packet.

Formatting data packets for compression

A method, apparatus, and computer program product can provide for procedures at an access terminal for handling the delivery of packets from the MAC entity to the RLC entity, with an aim to reduce the occurrence of RLC resets that might otherwise be caused by out-of-order processing of control packets following a serving cell change. In one example, a MAC entity may insert an identifier into a packet delivered up to the RLC entity, to indicate whether the packet arrived from the current primary serving cell. In another example, a serving cell change procedure may include steps to flush a queue at the MAC entity and kill any running reordering release timers. In these ways potential problems caused by out-of-order control packets can be reduced or avoided.

System and method for reducing resets during handovers in a single frequency dual carrier wireless communication system

Systems and methods are provided for sending caller ID information including a PTT signal up to a user interface module quickly, instead of first sending an incoming call alert or an incoming call alert and caller ID information without PTT information, and later sending the PTT information. A bypass alert message may be included with the caller ID information relating to the incoming call message sent from the main control task to the user interface module.

Call processing system and method

A method for creating a contact on a mobile device includes processing a request from a user to create a contact or group. After a predetermined period, if a confirmation of the creation of the contact or group has not been received, then the group is deleted from the mobile device. In one aspect the predetermined time period is measured from the time of the request to create the contact or group. In another aspect, the predetermined time period is longer than the group creation time.

Mobile telephone handset, mobile telephone system and method

Systems and methods are provided for voice buffering for a VOVC PTT call. The buffering starts before the VOVC call is established.

Push to talk voice buffering systems and methods in wireless communication calls

A system and method for reducing power consumed by an integrated electronic device. The device includes a personal data assistant (PDA) unit and a wireless telephone integrated in a common housing. A common display on the housing is used for displaying messages from both the PDA and the wireless telephone to a user. A controller, coupled to the wireless telephone, places the wireless telephone in a power-off state after expiration of a predetermined period of time following cessation of voice traffic activity on the wireless telephone. The controller switches the wireless telephone from the power-off state to a power-on state if, during operation in the power-off state, a user begins an attempt to place an outgoing call with the wireless telephone. The wireless telephone is unable to receive an incoming call when the wireless telephone is in the power-off state. However, the PDA is operable to receive information from the user through the display and display information to the user on the display when the wireless telephone is in the power-off state.
