Abstract
The present invention is directed to a system and method for providing services, such as location-based services, in a GPRS network. In a preferred embodiment of the present invention, a database including local geographical information is stored in a BSS (Base Station System). The BSS transmits data in the database to at lease one MS on dedicated DPCHs in idle packet frames. The MS populates its database with the data while in idle mode and provides the location-based services to a subscriber using its database.
Claims32
A telecommunications system for providing information services to a subscriber in a General Packet Radio Service (“GPRS”) network, the system comprising:
- a mobile station (“MS”) including a second database and being configured to a receive a request from the subscriber;
- and
- a base station system (“BSS”) including a storage area for storing a first database, the first database including data configured to provide the information services, the BSS being configured to transmit a Time Division Multiplexed Access (“TDMA”) frame comprising a plurality of time slots, a first portion of the plurality of time slots being used to transmit user data and a second portion of the plurality of time slots being idle, the BSS being configured to transmit the data to the MS in the second portion of the plurality of time slots,
- the MS being configured to while in idle mode, receive the data transmitted in the second portion of the plurality of time slots, populate the second database with the data received from the BSS, and use the second database to provide the information services to the subscriber in response to receiving a request from the subscriber.
1 more element
A method of providing information services to a subscriber in a General Packet Radio Service (“GPRS”) network, the method comprising:
- providing a storage area in a base transceiver station (“BTS”);
- modifying the storage area in the BTS to include a first database, the first database including services data needed to provide the information services;
- at the BTS, transmitting the services data to a mobile station (“MS”) in a Time Division Multiplexed Access (“TDMA”) frame, the TDMA frame comprising a plurality of time slots a first portion of the plurality of time slots transmitting user data and a second portion of the plurality of time slots not transmitting any user data, the services data being transmitted by the BTS in the second portion of the plurality of time slots, the MS including a second database;
- placing the MS in idle mode;
- and
- after placing the MS in idle mode, at the MS, populating the second database with the services data and using the second database to provide the information services to the subscriber.
3 more elements
A method for providing information services to a subscriber in a General Packet Radio Service (“GPRS”) network, the method comprising at a mobile station (“MS”) comprising a database:
- attaching to the GPRS network;
- activating a PDP context;
- receiving a temporary flow identifier (“TFI”) reserved for a downlink data comprising service data transmitted by a base transceiver station (“BTS”);
- after receiving the TFI, deactivating the PDP context and placing the MS in idle mode;
- after placing the MS in idle mode, monitoring a dedicated packet data channel (“PDCH”) to identify data packets associated with the TFI of the downlink data, the date packets associated with the TFI of the downlink data being transmitted on the dedicated PDCH in idle time slots of a TDMA frame;
- downloading any data packets identified;
- populating the database of the MS with the downloaded data packets;
- and
- using the second database to provide the information services to the subscriber.
6 more elements
A telecommunications system for use by a subscriber, the system comprising:
- a base station system (“BSS”) of a General Packet Radio Service (“GPRS”) network, the BSS comprising a first database storing information services data, the BSS being configured to transmit the information services data;
- a mobile station (“MS”) comprising a second database, an idle mode of operation, and an active mode of operation, the MS being in the idle mode of operation when the MS is attached to the GPRS network but does not have an active packet communication session therewith, the MS being in the active mode of operation when the MS has an active packet communication session with the GPRS network,
- the MS being configured to receive the information services data transmitted by the BSS while the MS is in the idle mode of operation, store the information services data in the second database, and use the second database to provide information services to the subscriber in response to receiving a request for the information services from the subscriber.
A telecommunications system for use by a subscriber, the system comprising:
- a base station system (“BSS”) of a General Packet Radio Service (“GPRS”) network, the BSS comprising a first database storing information services data, the BSS being configured to transmit the information services data in time slots of one or more Time Division Multiplexed Access (“TDMA”) frames not being used to transfer data during a packet communication session;
- a mobile station (“MS”) comprising a second database, the MS being configured to receive the information services data transmitted by the BSS in the time slots of the one or more TDMA frames not being used to transfer data during a packet communication session, store the information services data in the second database, and use the second database to provide information services to the subscriber in response to receiving a request for the information services from the subscriber.
A telecommunications system for use by a subscriber, the system comprising:
- a base station system (“BSS”) of a General Packet Radio Service (“GPRS”) network, the BSS comprising a first database storing information services data, the BSS being configured to transmit the information services data in frames of a packet data channel (“PDCH”) not being used to transfer data during a packet communication session;
- a mobile station (“MS”) comprising a second database, the MS being configured to receive the information services data transmitted by the BSS in the frames of the PDCH not being used to transfer data during a packet communication session, store the information services data in the second database, and use the second database to provide information services to the subscriber in response to receiving a request for the information services from the subscriber.
