Abstract:
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.

A system and method for routing information includes a resource manager. The resource manager includes a configuration table. The configuration table includes at least one group of physical gateway addresses, each of the at least one group of physical gateway addresses has a single and unique logical identifier. The resource manager is coupled to a plurality of gateways. A proxy coupled to the resource manager. The resource manager receives a register request message from a selected one of the plurality of gateways.
Abstract:
A network element (10), such as a Packet Data Serving Node, detects (31) a change in operational status of a mobile station during a communication session and, in response to detecting such a change, automatically increases (32) memory capacity as is available to support additional communication sessions while simultaneously persisting at least some session information for potential subsequent use during the communication session. For example, this response can occur upon detecting that a mobile station has changed from an active to a dormant status. Then, upon returning to an active status, the network element can use the persisted information to facilitate rapid reconstruction of infrastructure support for the mobile station's call participation.
Abstract:
There is provided a method of transmitting data between compact control stations using the Ethernet, including a network matching unit generation steps of separately generating the function of a network matching unit of each compact control station according to a data transmission function and data reception function, a data reception step of, when the network matching unit of one of the compact control stations is generated to have the data reception function at the network matching unit generation step, receiving operation maintenance data from the network matching unit of the other compact control station through TCP/IP communication using the Ethernet, and a data transmission step, when the network matching unit of one of the compact control stations is generated to have the data transmission function at the network matching unit generation step, transmitting control data and the operation maintenance data to the network matching unit of the other compact control station through TCP/IP communication using the Ethernet. The invention can perform TCP/IP communication using the Ethernet between the compact control stations having the BSM function and control station function to accurately transmit and receive the operation maintenance data without affecting call processing data between the compact control stations. The invention does not use an expensive network matching apparatus to lighten economic burden. Moreover, TCP/IP communication allows retransmission of data when there is data loss during communication so that accuracy in the transmission of the maintenance data can be guaranteed.
Abstract:
The device and method for scrambling/descrambling voice/data in a mobile communication system involves vocoding or bypassing a signal received from a radio channel interval, scrambling the vocoded or bypassed signal using a random number, sending the scrambled signal to a cable channel interval, descrambles the scrambled signal received from the cable channel interval, vocoding or bypassing the descrambled signal, and sending the vocoded or bypassed signal to the radio channel interval, thereby dramatically security of the data in the cable channel interval between the system vocoders and preventing overhearing of the voice.
Abstract:
A method for retransmitting data between two sides including a reception side and a transmission side in a mobile communication system including one or more mobile stations and one or more radio networks includes the steps of: by the reception side, storing data received from the transmission side in a first storage unit; as a result of an error-checking procedure, if the data are erroneous, requesting the transmission side to retransmit the data; by the transmission side, transmitting to the reception side a first information related to retransmission and retransmitting the requested data; by a combination unit included in the reception side, combining the retransmitted data with the data stored in the first storage unit; if the combined data are not erroneous, clearing the data and the retransmitted data from the first storage unit and transmitting the combined data to a first upper layer included in the reception side; and in response to an ACK signal from the reception side representing that normal data are received, clearing by the transmission side the retransmitted data from a second storage unit.
Abstract:
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.
Abstract:
A method for processing a call in an asynchronous mobile communication system including an asynchronous mobile station, an asynchronous radio network, wherein a synchronous core network is interlocked, includes the steps of: setting up the call in case a calling call message is generated in the mobile station; establishing a channel between the asynchronous mobile station and the asynchronous radio network; handling basic information for assigning a radio resource; performing a cipher establishment; establishing the radio resource; performing a configuration for a service; and transmitting a phone call stand-by message to a user.
Abstract:
A method for cell selection of an asynchronous mobile station in an asynchronous mobile communication system including an asynchronous mobile station, an asynchronous radio network, in case the asynchronous mobile communication system is interlocked with a core network, includes the steps of: storing information related to the core network transmitted from the asynchronous radio network in a memory or a user subscriber identity module (USIM) of the asynchronous mobile station before power-off of the asynchronous mobile station of the asynchronous mobile station; at power-on of the asynchronous mobile station, determining what type of the core network is interlocked by analyzing the information of the core network; beginning any one of a global system for mobile communication (GSM) cell procedure and an American national standards institute (ANSI) cell procedure; finding a cell suitable for providing a service, based on a type of the core network that was determined; and performing a location registration of the found cell.
Abstract:
A system and method of transmitting information between a mobile node and a home agent of the mobile node. The mobile node has an associated home AAA server. The address of the HAAA is determined. The HAAA is contacted and, responsively, receives information indicating a methodology of determining the home address of the mobile node. A proxy server determines the address of the home agent using information received from the PDSN. The information is routed from the mobile node to the home agent having the address.
