Definitions

  • the present invention relates generally to signaling in a GSM communication system, and in particular, the present invention relates to a method for receipt of paging messages from a circuit-switched data domain while a mobile station is involved in the interchange of packet-switched data.
  • GSM Global System for Mobile Communications
  • GPRS General Packet Radio Service
  • GSM Global System for Mobile Communications
  • GPRS General Packet Radio Service
  • GSM Global System for Mobile Communications
  • GPRS General Packet Radio Service
  • User applications may include Internet browsers, electronic mail and so on.
  • the European Telecommunications Standards Institute (ETSI) GSM specifications define what is referred to as a "mobile station class" for GPRS mobile stations.
  • the mobile station class specifies some of the behavior to which a mobile station must conform regarding its operation in packet mode, circuit-switched mode, or both packet and circuit-switched mode.
  • one such mobile station class is a Class A mobile station which supports simultaneous attachment, monitoring, activation, invocation and traffic flow on both circuit-switched voice and packet- switched data services.
  • a Class B mobile station has been defined to support only simultaneous attachment, monitoring and activation on both circuit- switched voice and packet-switched data services, with invocation and traffic flow possible on either service on a mutually exclusive basis.
  • a Class C mobile station is defined to support only non-simultaneous attach, i.e. mutually exclusive attach, on either circuit-switched voice or packet-switched data services.
  • Mobile station classes may also be assigned, or changed, in some cases by the user, subject to limitations such as manufacturer's options and equipment limitations. For example, a user application may have the ability to issue a command to change the mobile station class of the subscriber equipment currently in use. The mobile station classes are therefore to be treated as "effective" classes, as users may exercise some control over mobile station class identity.
  • Efforts are presently underway to further develop ETSI GPRS specifications to specify required channelisation and signaling techniques that allow a mobile station, having a single receiver/transmitter, to handle a simultaneous GSM voice and packet session. This effort has led to the creation of a dual transfer mode (DTM), in which both GSM voice and GPRS, or EDGE, data can be interchanged on the same radio frequency (RF).
  • DTM dual transfer mode
  • RF radio frequency
  • Current GPRS networks include a process for coordinating transmission of paging for both circuit-switched data and packet-switched data services in which the GPRS network sends paging messages for circuit-switched service on the same channel as used for packet-switched services, i.e., on a GPRS paging channel or on a packet associated control channel.
  • the mobile station needs to monitor the packet associated control channel (PACCH) while the mobile station is currently engaged in packet-switched transfer, or the GPRS paging channel when the mobile station is not currently engaged in packet switched or circuit-switched data transfer.
  • PACCH packet associated control channel
  • a mobile station 100 such as a wireless telephone device, communicates with a circuit-switched network 102 and a packet data network 104 by transmitting signals to and receiving signals from a base station 106.
  • the base station 106 is coupled to a base station controller 108, which in turn is coupled to a mobile switching center 110 via an interface 112 commonly referred to as an "A interface", and the mobile switching center 110 in turn interfaces with the circuit- switched network 102.
  • a interface interface 112 commonly referred to as an "A interface”
  • circuit-switched data it is possible for circuit-switched data to be transmitted between the mobile station 100 and the circuit-switched network 102 along a signal path that includes the base station 106, base station controller 108, and the mobile switching center 110.
  • the base station controller 108 is coupled to a Serving GPRS Support Node (SGSN) 114, which keeps track of the location of the mobile station 100 and performs security functions and access control, and interfaces with the packet data network 104.
  • SGSN Serving GPRS Support Node
  • packet-switched data it is possible for packet-switched data to be transmitted between the mobile station 100 and the packet data network 104 along a signal path that includes the base station 106, base station controller 108, and the SGSN 114.
  • a prior art GPRS network enables a mobile station operating in a packet transfer mode to receive a circuit-switched paging message by using an optional interface 116, commonly referred to as a "Gs interface", connecting the mobile switching center 110 and the SGSN 114.
  • the Gs interface 116 enables the mobile station 100 to receive a circuit-switched paging message while engaged in a packet- switched data transfer, by transmitting the circuit-switched paging information from the mobile switching center 110 directly to the SGSN 114, along the Gs interface 116, rather than transmitting the paging message from the mobile switching center 110 through the base station controller 108 to the mobile station via a circuit-switched paging channel on the combined control channel (CCCH).
  • CCCH combined control channel
  • one of the problems associated with providing a Class A capable mobile station operating in an environment which does not support the optional Gs interface 116 is that, while engaged in a packet-switched data transfer whereby packet data is being interchanged between the mobile station 100 and the packet data network 104, the mobile station 100 is unable to schedule receipt of a circuit-switched paging block without preempting the reception of data from a packet data channel (PDCH), which would result in a loss of packet data throughput, since retransmissions would be required to make up for missed data blocks.
  • PDCH packet data channel
  • the packet data control channel is organized as a multiframe 100 having fifty-two frames 102 and twelve data blocks BO-B 11 , in which each data block BO-B 11 is distributed over four time division multiple access (TDMA) frames.
  • An "idle" or “search” frame 106 located after every three data blocks, enables the mobile station to perform adjacent cell signal measurements, synchronization and verification of synchronization status on adjacent cells, interference measurements, and so forth.
  • Each data block BO-B 11 is made up of four frames, each of which has a frame period f equal to 4.61538 milliseconds, and a block period b that is equal to 18.4616 milliseconds, while each idle frame 106 has an idle frame period I that is equal to the frame period f, or 4.61538 milliseconds.
  • the total period of the multiframe 100 structure of the packet data channel is equal to 240 milliseconds.
  • a combined control channel is organized as a multiframe
  • the multiframe includes nine groups of four frames 1-9 that include paging and access grant control channels, a four contiguous frame block 114 that is a broadcast channel, and two idle frames 116 positioned between each group of eight frames.
  • the total period of the multiframe 108 structure of the paging and access grant control channel is equal to 235.385 milliseconds.
  • a paging group to which an idle frame refers at one point in time differs as time progresses, limiting the number of appropriate paging blocks visible to the mobile station in an idle frame during a packet transfer.
  • FIG. 1 is a schematic diagram of a communication network in a GPRS system.
  • FIG. 2 is a schematic diagram of multiframe structures for a packet data channel and a combined control channel.
  • FIG. 3 is a schematic diagram of a communication network, according to the present invention.
  • FIG. 4 is a signal flow diagram of a signaling path in a communication network according to the present invention.
  • the present invention is a method for a notifying a Class A GPRS dual transfer mode mobile station, operating in a packet transfer mode, of a circuit- switched paging message.
  • the mobile station aborts a temporary block flow (TBF) on which the mobile station is currently interchanging packet-switched data, and returns to a combined control channel (CCCH) having random access to set up the circuit-switched voice connection corresponding to the circuit-switched paging message.
  • TBF temporary block flow
  • CCCH combined control channel
  • the combined control channel is a signaling channel that sets up a simultaneous voice channel and data channel according to dual transfer mode requirements. As a result, the mobile station is able to continue with the previously aborted packet data transfer and acquire a circuit-switched voice session.
  • a communication network 200 includes a mobile switching center 202, and a plurality of cell sites 204.
  • Each cell site 204 includes a base station 206 coupled to a base station controller 208.
  • a protocol control unit 210 is coupled to or contained within each base station controller 208, and each protocol unit 210 interfaces with a Serving GPRS Support Node (SGSN) 212 which in turn interfaces with a packet data network 214.
  • the base station controller 208 is coupled to the mobile switching center 102 along an A interface 215, and the mobile switching center 202 in turn interfaces with a circuit- switched network 216.
  • SGSN Serving GPRS Support Node
  • the SGSN 212 can also be connected to other SGSNs belonging to other service providers, which in turn can also be connected other SGSNs, and so forth.
  • a mobile station 218, such as wireless telephone device, is adapted to communicate with base stations associated with each base station controller 208 to maintain communications with another mobile station, the circuit-switched network 216, or the packet data network 214.
  • the mobile station 218 includes a transceiver 220 to receive signals from, and to transmit signals to the base station controller 208, and a processor 222 to process the signals sent to and received from the base station controller 208.
  • the SGSN 212 keeps track of the location of the mobile station 218, and performs security functions and access control. It is understood that although only one mobile station 218 is shown in FIG.
  • FIG. 4 is a signal flow diagram illustrating a signaling path in a communication network according to the present invention. As illustrated in FIGS. 3 and 4, when the mobile station 218 is initially engaged in packet data transfer, an existing packet data transfer, line 224 of FIG. 4, takes place along a temporary block flow (TBF) so that the mobile station 218 is engaged in a packet data interchange via the SGSN 212 in packet-transfer mode.
  • TBF temporary block flow
  • the circuit- switched message is sent to the mobile station 218 along the existing paging channel.
  • the base station controller 208 determines both that the mobile station 218 supports a dual transfer mode, and that the mobile station 218 is currently in a temporary block flow, the base station controller 208 sends a message to the protocol control unit 210, line 228, informing the protocol control unit 210 that a circuit-switched page is pending for the identified mobile station 218, and instructing the protocol control unit 210 to send a ciruit-switched paging message in a radio link control (RLC) control block to a radio resource (RR) layer of the mobile station 218.
  • RLC radio link control
  • RR radio resource
  • FIG. 5 is a flow chart of a mechanism in a communication network for notifying a mobile station of a circuit-switched paging message, according to the present invention.
  • the base station controller determines whether the mobile station is capable of operating in a dual transfer mode, Step 310, using the mobile station class mark. If the base station controller determines the mobile station is not capable of operating in dual transfer mode, the circuit-switched paging message is sent to the mobile station on the paging channel (PGCH), Step 320.
  • PGCH paging channel
  • the base station controller determines whether the mobile station is currently engaged in packet-switched data interchange activity, Step 330. If the base station controller determines in Step 330 that the mobile station is not currently engaged in packet-switched data interchange activity, the circuit-switched paging message is sent to the mobile station on the paging channel (PGCH), Step 320.
  • PGCH paging channel
  • Step 350 Upon receiving the RLC/MAC control block, the mobile station realizes that it is being paged, aborts its current packet data transfer, and begins monitoring a combined control channel with random access to set up the circuit-switched voice connection, Step 350, which may include a user data channel with allocation for a voice channel and a data channel according to dual transfer mode requirements.
  • the present invention provides a mechanism for receipt and handling of a paging message that originates from a circuit-switched domain while a mobile station is engaged in a packet-switched domain data interchange.
