Definitions

  • This invention relates in general to wireless mobile communication systems, and more particularly to methods of sending messages between mobile communication devices and between mobile communication devices and clients using data network equipment.
  • Wireless mobile communications has had a profound impact on the way many people conduct business, and it has provided a great convenience to the general public. In some situations, however, it may be inappropriate or otherwise undesirable to use a mobile communication device, such as during an important business meeting, or any other time when it would be considered disruptive. Yet it may be desirable to transmit or receive a short non verbal message that does not necessarily require a real-time response, or any response at all.
  • This type of messaging is done regularly between fixed computing stations, such as by electronic mail, or to a mobile device such as a pager.
  • Some methods even provide for pseudo real-time response, such as the so called online chat where multiple users can simultaneously engage in a discussion with low apparent latency.
  • Instant messaging is a variety of the online chat where discussion is between two people located at remote stations.
  • Instant messaging and online chat in general involve activating a software program at a computer that is connected to a network.
  • the software program is an instant messaging "client" which runs on a general purpose computer connected to a network.
  • the instant messaging client requests the users account information, and connects to a messaging server.
  • the messaging client relays the account information to the messaging server, along with the present network address of the machine currently being used for the present instant messaging session. This allows the user to use different machines at different times with the same instant messaging account, provided that the machine has a copy of the instant messaging client program and is connected to the network.
  • An instant message is an alpha-numeric text string composed by a first user, typically in a text entry window in the program's user interface, that is sent to a second user or a group of users over the instant messaging server.
  • the server forwards this message to the final recipient's client and the client displays the message as soon as it is received.
  • the fact that conventional instant messaging services rely on servers that queue messages indicates that there is always the server processing delay, which, during peak times of messaging traffic can be noticeable.
  • Other types of messaging such a paging and electronic mail (email) also suffer from inherent delivery latency during periods of peak network activity.
  • Wireless messaging such as paging and email offer the benefit mobility and can present a minimal disturbance, unlike receiving a mobile phone call where the user engages in a conversation with the calling party upon receiving a call. Therefore there is a need for a wireless instant messaging system for mobile clients that does not delay messages, even during times of peak traffic.
  • FIG. 1 shows a communication system for performing wireless instant messaging, in accordance with the invention
  • FIG 2 shows a flow chart diagram of a method of performing wireless instant messaging between mobile communication devices, in accordance with the invention.
  • FIG. 3 shows a diagram of a typical data packet including a header and a payload
  • FIG. 4 show a flow chart diagram of a method of determining if a mobile station is presently online, in accordance with the invention

  • server queued it is meant that the message sent from the sender's equipment is temporarily stored on a server before it is delivered.
  • Examples of such systems include email, paging, and internet chat messaging.
  • a chat server may also duplicate messages so that they may be routed to multiple users involved in the same discussion.
  • the messaging network delay is determined by the amount of dedicated resources and the volume of messaging traffic. Obviously as the traffic volume increases, the more demand there is on system resources, and at some point delays begin to be experienced in message delivery.
  • many messaging systems are blind, such as paging systems, meaning that the sender has no way of knowing if the intended receiver actually received the message.
  • the present invention mitigates these problems by avoiding the use of a server, and providing feedback as to whether or not the intended receiver actually received the sent message. This is accomplished by use of a direct client to client communication over the network. In the preferred embodiment the message is transmitted through the system without being queued at any server.
  • a dispatch channel instead of a more conventional duplex channel is that roughly half the system resources used for a duplex connection are utilized since only a half duplex connection is needed at any one instant.
  • a mobile communication device or mobile station 102 is shown, connected over an air interface 103 to a fixed equipment network including an enhanced base transceiver (EBTS) 104.
  • the mobile station comprises a display means for displaying information such as text and various icons, and an input means such as an alpha- numeric keypad.
  • EBTS enhanced base transceiver
  • It is a mobile wireless communication device, meaning that mobile station may move from location to location within a serving area and maintain contact with the fixed equipment network by handing over to different base sites, as is well known in the art.
  • the mobile station is capable of making both dispatch and telephone calls, such as any of the communication devices sold under the trade name iDEN, manufactured by Motorola, Inc.
  • the EBTS is operably connected to a base site controller (BSC) 106, which controls one or more EBTS units on a given site to establish a serving cell.
  • BSC base site controller
  • MDG mobile data gateway
  • the BSC may also be operably connected to, for a example, a mobile switching center (not shown), as is well known in the art, for establishing duplex telephone calls over a public switched telephone network.
  • dispatch call it is meant any half duplex type of communication where the parties alternatively speak and listen.
  • the MDG 108 is operably connected to a dispatch application processor
  • DAP 110 which is a communication agent processor for facilitating dispatch calls. These calls are half duplex, where only one station talks at a time, and the receiving stations can only listen. A dispatch call may be between two or more stations.
  • the system identifier of the station the user wishes to call, or the talk group identifier the user wishes to speak in is selected at the user's station.
  • the station Upon engaging the push-to-talk button, the station sends the information to the DAP, which quickly locates the serving cell(s) of the target stations by examining a dispatch visit location register (D-VLR) 112.
  • D-VLR dispatch visit location register
  • the D-VLR works substantially similar to that of a visit location register used in mobile telephone systems to keep a timely record of the serving cell in which each connected mobile station is presently located. This facilitates quick routing of dispatch calls to the cell or cells of the other stations which a calling station is calling. As mobile stations change locations, their cell affiliation is updated in the D-VLR.
  • the MDG may also be connected to outside networks through, for example, an IP router 120, which connects the wireless system 100 with a data network such as, for example, the Internet 122, where there are other servers 124 and network chat client machines 126.

  • the second mobile station While it is receiving the instant message, or shortly after receiving the message, the second mobile station sends an acknowledgement back to the first mobile station (220), and displays the received message in an alphanumeric capable display (222). Preferably, the second mobile station alerts the user an audio or visual alert, or both, upon receiving the message. The message may be displayed at the users request upon perceiving the alert, or it may be displayed automatically. Presently, the instant message is finished (224).
  • the first mobile station may "ping" the second mobile station prior to sending the message, or even prior to the first user composing the message, as illustrated in FIG. 4.
  • the first user may be curious as to whether the second mobile station is in use, and hence able to receive an instant message.
  • the first user merely selects the identifier of the second mobile station from within an appropriate operating mode of the first mobile station (400), and takes some action, such as pressing a push-to-talk button.

This is the same as would preferably happen in the previous case had the MDG not found the second mobile station's identifier in the D-VLR when the whole message was attempting to be sent to the second mobile station. If the target identifier is found, the MDG returns an acknowledgment (408), and the user can then proceed to compose a message. In an alternative embodiment, the user can compose the message and if the second mobile station is not available, the first mobile station may automatically repeat attempting to send the message at preselected intervals.

  • the first mobile station transmits the message, it begins a timer. If after a preselected period of time there has been no acknowledgement received, the first mobile station displays a fail message to the user. Because of the very low latency in transmitting a message from one mobile station to another with this method over such a fixed equipment network, it is contemplated that no more than a few seconds will be needed to receive a proper acknowledgement. So if, for example, 5 seconds have elapsed and no acknowledgement has been received, the first mobile station will fail the transmission.

Abstract

L'invention concerne une première station mobile (102) utilisée pour envoyer un message à une seconde station mobile (118). L'utilisateur de la première station mobile désigne la seconde station mobile comme cible, et compose un message soit par enregistrement vocal, soit par introduction d'un texte dans la première station mobile. La station mobile transmet alors le message et l'identificateur de la cible à un réseau d'équipement fixe comprenant un émetteur-récepteur de base perfectionné (104), un contrôleur de site de base (106) et une passerelle de données mobile (108). La passerelle de données mobile utilise des ressources d'appel instantané pour acheminer le message sans le mettre en file d'attente ou sans le stocker grâce à l'obtention de l'emplacement courant de la seconde station mobile d'un registre (112) de localisation des visiteurs. La passerelle de données mobile achemine alors le message de façon similaire à l'établissement d'un appel instantané entre la première et la seconde station mobile.
