摘要:
A subscriber unit (122) in a wireless messaging system records (404) a message sequence number corresponding to a message received, and an indication of whether the subscriber unit acknowledged the message. Upon registration with a two-way portion (104) of the wireless messaging system, the subscriber unit reports (532, 526), to the two-way portion, information of a type selected from (a) missing message sequence numbers, and (b) message sequence numbers corresponding to messages received and not acknowledged, the type selected (524) being that which generates a smaller amount of inbound traffic.
摘要:
The present invention reduces network operator memory requirements, administrative overhead, and operational costs by enabling a solution for SS7/IP communication that uses a single domain (e164.arpa) in ENUM for numbering schemes such as E.164, E.212, and E.214. Employing the present invention enables the SUA to deliver SCCP-user messages to the destination node using Global Title Information based on IMSI or E.164 numbers. Network operators populate ENUM databases with MAP URIs associated with mobility services such as MSC, HLR, and VLR. End point service node IP addresses, associated with a set of services, are stored in ENUM corresponding to the SAPC belonging to the local operator for a given PLMN. These end node IP addresses then are returned in the ENUM/DNS response to an E.164-based query.
摘要:
Redundancy is provided in a communication network including a plurality of nodes (114, 112, 106, 102) by a first node (114) receiving and storing (402) a message (210) in a first memory (202). The first node then transmits (404) the message to a first one of a plurality of second nodes (112), and removes (412) the message from the first memory after receiving an acknowledgment from any one of the plurality of second nodes. The first one of the plurality of second nodes receives (502) and stores (504) the message within a second memory (302) and stores (506) the message within a third memory (110) accessible to the plurality of second nodes. The first one of the plurality of second nodes transmits (508) the acknowledgment to the first node after storing the message in both the second and third memories.
摘要:
A control system (101) is utilized by a radio communication system for communicating with selective call transceivers (102). The control system (101) includes an input interface (114) for receiving a message from a user, a processing system (111) for processing and storing the message, and a local area network (LAN) for controlling a transmitter system (105) for transmitting the message. The LAN has an architecture providing communication redundancy. The LAN includes at least one data communication path (118) for linking data communications to and from at least one data communication device (112, 114). The LAN further includes a first and second ethernet switch (108, 109) coupled to a first and second end (120, 122) of the at least one data communication path (118) for routing the data communications thereto and therefrom. The processing system (111) is coupled to the ethernet switches (108, 109) for transmitting and receiving the data communications.
摘要:
A distributed signaling system seven (SS7) call handling system (107) includes an SS7 message transport protocol level three (MTPL3) processing module (202), an SS7 message transport protocol lower level (MTPLL) processing module (258), and a local interconnection media (240). The SS7 MTPL3 processing module (202) includes an SS7 MTPL3 network layer (204) and an MTPL3 local network interface (218). The SS7 MTPLL processing module (258) includes an SS7 message transport protocol level one (MTPL1) physical layer (259), an SS7 message transport protocol level two (MTPL2) link layer (256), and an MTPLL local network interface (254). The local interconnection media (240), for example an Ethernet, couples the MTPL3 local network interface (218) to the MTPLL local network interface (254).
摘要:
A distributed SS7 call terminating processor (102) for processing calls received over an SS7 network (105) includes a set of N simultaneously active digital channel interfaces (DCIs) (121) sharing a common signaling point code. The set of DCIs (121) receives common channel signaling messages. Each of the N simultaneously active DCIs (258) includes an SS7 message transfer part level one (MTPL1) physical layer (259) coupled on a one to one basis to a common channel signaling link (110), an SS7 message transfer part level two (MTPL2) link layer (256) and an SS7 message transfer part level three (MTPL3) network layer (253) having the common signaling point code. An operation and maintenance controller (108) includes a configuration function (315) that configures each SS7 MTPL3 network layer (253) in the set of N simultaneously active DCIs (121) to have the common signaling point code.
