A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and applying a variable size codebook for stateful compression or for stateless compression. The method also includes determining if a match exists between the plurality of bits and a selected one of a plurality of bit patterns and communicating a payload present (PP) header bit pattern corresponding to the selected bit pattern in place of the plurality of bits associated with the communications flow.

System and method for implementing a variable size codebook for compression in a communications environment

An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and comprising a compression module that is operable to receive a plurality of bits associated with a communications flow, to inspect the bits, to determine whether one or more samples included in the flow should be suppressed, and to compress the samples. The cell site element is coupled to a back-up device that is operable to assume responsibility for active flows in a case where a primary device fails. Data is exchanged between the primary device and the back-up device, the data guiding the back-up device in how to process the active flows.

System and method for synchronizing a back-up device in a communications environment

A method for compressing information is provided that includes receiving a plurality of bits associated with a communications flow and electing whether to perform compression and multiplexing operations based on a level of traffic propagating in a network.

System and method for discretionary multiplexing and compressing in a communications environment

A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow. The method also includes configuring multiplexing for a link, which is selected for transmission of data, by using a maximum fragment parameter associated with the link. The maximum fragment parameter is used as an upper limit whereby if the maximum fragment parameter is smaller than a maximum multiplex parameter, an incoming packet is multiplexed only to the maximum fragment parameter size such that multiplexed packets are not fragmented.

Providing a multicast service includes maintaining multicast service information at an application server. The multicast service information describes a multicast service having an associated subscriber, and the multicast service is operable to deliver multicast content from a multicast source. A cell supporting a user device associated with the subscriber is determined, and creation of a bearer path for the multicast service is initiated. Delivery of the multicast content to the user device is enabled using the bearer path.

An apparatus for providing fault and error tolerance in a network environment is provided that includes an aggregation node associated with a base station controller and operable to receive a packet that includes an error. A portion of the packet is discarded, the packet being associated with a communications flow. The aggregation node being further operable to perform a selected one of injecting a subframe into the communications flow and playing one or more previous frame bits from a frame memory in response to the error.

System and method for providing fault and error tolerant communications in a network environment

Performing compression includes receiving at a compressor a flow comprising packets, where each packet has a packet identifier. The packet identifiers are associated with a predetermined increment, but any change in the predetermined increment is ignored. The packets are compressed, and the flow is transmitted to a decompressor.

Performing compression of user datagram protocol packets

In a communication network, link efficiency modules aggregate packets into multiplexed packets to provide efficient use of communication links. To handle varying levels of network traffic, the link efficiency modules provide multiple modes of operation to balance bandwidth efficiency against packet latency.

Link efficiency schemes for packet transport

Within a hard handoff procedure of a mobile terminal from a first radio sector to a second radio sector, a handoff manager requests the allocation of network resources associated with the second radio sector for the mobile terminal. If the second radio sector does not have sufficient network resources to support the mobile terminal, the handoff manager instructs the mobile terminal to switch into a dormant mode. By doing this, the handoff manager can delay the disconnection of the packet data session until there is sufficient network resources or until an internal packet data protocol error occurs due to a request timing out. In the case that sufficient resources become available, the handoff manager instructs the mobile terminal to return to a connected mode. One advantage of this procedure is the reduced need to re-establish a data packet session in cases that there is a temporary lack of sufficient network resources during a hard handoff.

Apparatus and method for hard handoff of data packet transmissions

A technique for prioritization of access and paging in cellular communications systems. In the downlink direction, where a single Paging Channel is configured, a plurality of queues are created corresponding to individual services or groups of services with the same priority. Page attempts are assigned to the appropriate queue according to a pre-determined service-to-queue mapping. Pages from the queues are sent on the Paging Channel in accordance with a pre-determined dequeuing algorithm. Where multiple Paging Channels are used, page attempts are assigned to the appropriate Paging Channel according to a pre-determined service-to-Paging Channel mapping. In the uplink direction, where a single Access Channel is configured, each mobile station includes in the Access Message a parameter representing the number of consecutive unsuccessful access attempts which have been initiated by the mobile station. This information is received by the base station and used to enable/disable services according to a predetermined priority. Which services are enabled/disabled is broadcast to each mobile station in the cell as a parameter in the Access Parameters Message. Mobile stations seeking to access services which have been disabled abandon their access attempts. Where multiple Access Channels are configured, services are mapped to the Access Channels according a pre-determined service-to-Access Channel mapping. Mobile stations initiate access attempts on the Access Channels as determined by the service-to-Access Channel mapping.

Service prioritized access and paging

A radio link adapter for wireless transmission of multimedia data through a communication link between a radio access network (RAN) and a mobile station (MS), is provided. The information flow is constantly monitored to determine an information element (IE) type of service requirements and for allocating paired radio link adapters (RLAs) designed to fit the respective type of service requirements. A connection end may be initially established in the RAN or in the MS. An analyser monitors the link, detects the type of service (ToS) required, and dynamically allocates the appropriate type of RLA to the connection. There is no need to recreate the connection when selecting the adapter for transporting various types of services and therefore, the transport of the information flow of a specific ToS over the communication link is optimized, while maintaining the end-to-end quality of service (QoS).

Dynamic radio link adaptation

A method for allowing subscribers of a telecommunications network to change easily between sets of desired features is disclosed. The home location register stores multiple profiles of all subscribers within its serving region along with an active profile number field indicating the list of features currently available to each subscriber. Upon initial registration of the mobile station at a mobile switching center communicating with the home location register, a default profile is extracted from the home location register. Upon dialling a special code or number, a subscriber can prompt a change of profile containing a different set of features for different users of the mobile station or for different times of day or geographic areas. In this way, subscribers bypass the routine of having to contact an agent in order to add or remove features and are allowed to switch among multiple profiles at will. A personal identification number can be used to enhance the security of the profile change procedure.
