摘要:
A system and method for integrating the call control signaling pathway with data network access components. A call control server agent is resident on a network device that provides a first interface from an access network to a packet-switched data network. The call control server agent receives data session initiation requests and passes the requests to the call control server agent. The call control server agent also performs proxy server functions and provides a source of information relating to data sessions directly to the access network.

A packet data serving node (200) that receives (101) from a mobile station (408) that already has an existing home agent-facilitated data session an indication of a present need to conduct an interactive real-time session is able to establish (102) a non-home agent-facilitated interactive real-time session for that mobile station notwithstanding and apart from the existing home agent-facilitated data session. By one approach this can comprise treating traffic as corresponds to the non-home agent-facilitated interactive real-time session as simple Internet Protocol traffic while treating traffic as corresponds to the existing home agent-facilitated data session as mobile Internet Protocol traffic. If desired, different Internet Protocol address can be used to facilitate such treatment alternatives. By one approach, the aforementioned packet data serving node assigns the Internet Protocol that the mobile station uses in conjunction with the non-home agent-facilitated interactive real-time session.

A network element can monitor (105) communication resource usage by, for example, a first end user. A determination (106) can then be had as to whether this first end user's communication resource usage exceeds a predetermined individual level of usage for that first end user (as distinguished, for example, from an upper limit as might be generically applied across an entire user population). When the first end user's communication resource does exceed this predetermined individual level of usage, automatic limitations regarding the first end user's communication resource usage can be imposed (108) while nevertheless continuing to facilitate the end user's communication resource usage.
摘要:
A wireless access gateway (70) obtains (11) substantially current information regarding its own performance capacity. That information is communicated to a network element (90). In a preferred approach, the wireless access gateway integrally combines (12) the substantially current information with at least one call management message to provide a composite message, which composite message is then transmitted (14). The network element then preferably automatically makes determinations (82) regarding selection of a particular wireless access gateway to support a given call as a function, at least in part, of the substantially current information regarding wireless access gateway performance capacity.
摘要:
While one node (such as a wireless mobile node) facilitates a point-to-multipoint communication via a communications network (10), communication requests from other nodes in the multipoint audience are queued in a node queue (17). At some point (in a preferred approach, at the conclusion of the transmission by the one node), and typically for a predetermined amount of time, communication requests are further noted. These more recent indicia of a desire to communicate are then utilized to modify the node queue. Subsequent communications are then arranged, at least in part, based upon the modified node queue.
摘要:
A network element (20), such as a PDSN or home agent, upon determining (11) a need to effect a call management operation, then determines (12) whether to constrain the facilitation of that call management operation. When determining that the call management operation should be constrained, the network element can facilitate (14) that call management operation while imposing an artificial facilitation constraint. For example, the rate at which the call management operation is executed with respect to a plurality of existing calls can be specified.
摘要:
A network element (300) having a mobile Internet Protocol call processor (301) is provisioned with at least a first mode of operation and a second mode of operation. The first mode of operation causes the processor to require authentication information from an authentication server before supporting a mobile Internet Protocol call whereas the second mode of operation permits the processor to support a mobile Internet Protocol call notwithstanding an absence of authentication information. A mode of operation selector (305) selects the mode of operation to be utilized and can respond to, for example, present unavailability of authentication services and/or administrative preferences. Pursuant to one approach, information such as accounting information can be developed and maintained as corresponds to mobile Internet Protocol calls that are supported in the absence of authentication.
摘要:
Prepaid Internet Protocol-based services for a plurality of Internet Protocol-based services are provisioned by automatically and dynamically determining, for a given mobile node, the Internet Protocol-based services for which the mobile node has prepaid access, and then providing an authentication message (for example, to a supporting packet data serving node) that comprises, at least in part, identification of at least a first particular Internet Protocol-based service to which at least a first prepaid accounting quota attribute applies.
摘要:
A computationally simple yet powerful forward error correction code scheme for transmission of real-time media signals, such as digitized voice, video or audio, in a packet switched network such as the Internet. An encoder at the sending end derives p redundancy blocks from each group of a k payload blocks and concatenates the redundancy blocks, respectively, with payload blocks in the next group of k payload blocks. At the receiving end, a decoder may recover up to p missing packets in a group of k packets, provided with the p redundancy blocks carried by the next group of k packets. The invention thereby enables correction from the loss of multiple packets in a row, without significantly increasing the data rate or otherwise delaying transmission.
摘要:
A method and apparatus for improving the speed and quality of end-to-end data or real-time media transmissions over an internet is disclosed. A data stream representing a media signal at a given level of compression is processed just before the data stream enters the internet. A less compressed data stream representing the same media signal is generated transmitted through the internet. Due to the lower level of compression, the underlying media signal is less sensitive to packet loss in the internet and, as a result, the media signal that arrives at the receiving end will tend to be more continuous and clear.
