    Description


    [0001] The present invention relates to the field of mobile terminal technologies and specifically, to a mobile terminal network and a method for mobile terminals to receive text messages.

    [0002] Along with continuous development of mobile terminal technologies, users are imposing higher and higher requirements on mobile terminal functions.

    [0003] Regarding cell phones, for example, there are Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS) networks. Class B cell phones cannot have both GSM service and GPRS service simultaneously. GSM service has higher priority in operations. A network locates corresponding mobile terminals through broadcasting paging messages. After comparison and authentication, a mobile terminal responds with a Paging Response message if a paging message is determined to be for itself. In case of a GSM paging while a mobile station is performing GPRS service, it will suspend the GPRS service, carries out the GSM service first, and then restores the GPRS service. Text message service is also one of the GSM services, which has higher priority than GPRS services do.

    [0004] Baseband chips have limited capabilities in the prior art. When a cell phone is in the Packet Transfer state, therefore, it is unable to receive paging by Common Control Channel (CCCH) in the circuit switch domain (CS domain) and meanwhile, it is unable to decode Packet Paging Channel in the packet switch domain (PS domain). If a network pages the cell phone at this time, the cell phone does not respond. The network concludes that the cell phone is not accessible and stops paging the cell phone. When the cell phone exits the Packet Transfer state, the network will not re-page the cell phone since the cell phone does not report its position information to the network, leading to delays of text message reception. It will end only when the mobile terminal performs periodic position update, which might be several hours later. As a result, the reception of text messages by users will be delayed and the users will be affected. How to promptly and rapidly receive and send text messages when a mobile terminal is switching in the Packet Transfer state is one of the research directions in the field of mobile terminal technologies.

    [0005] Prior art is disclosed in documents US2004/090951 A1 and EP 1 925112 A2.

    [0006] An object of the present invention is to provide a method for mobile terminals to receive text messages so as to promptly and rapidly receive and send text messages when a mobile terminal is switching in the Packet Transfer state.

    [0007] The various embodiments for which protection is sought are set out in the appended claims.

    [0008] An embodiment of the present invention is carried out in this way: A method for mobile terminals to receive text messages, said method comprising the following steps:
    • A network server pages a mobile terminal and determines whether text messages can be sent;
    • If said mobile terminal is in the Packet Transfer state, it does not respond to the paging by said network server;
    • If said network server does not receive a response from said mobile terminal, it terminates the paging until receiving position update information from said mobile terminal;
    • After updating the position, said mobile terminal sends position update information to said network server;
    • Said network server continues to page said mobile terminal so as to take an action to send text messages.


    [0009] Another object of the embodiment of the present invention is to provide a mobile terminal network, comprising a network server and at least one mobile terminal,
    • the network server pages a mobile terminal and determines whether text messages can be sent, if said mobile terminal is in the Packet Transfer state, it does not respond to the paging by said network server;
    • If said network server does not receive a response from said mobile terminal, it terminates the paging until receiving position update information from said mobile terminal;
    • After updating the position, said mobile terminal sends position update information to said network server; said network server continues to page said mobile terminal so as to take an action to send text messages.


    [0010] According to an embodiment, after said network server continues to page said mobile terminal according to the position update information of said mobile terminal, said mobile terminal responds to the paging by said network server and receives text messages sent by said network server.

    [0011] According to an embodiment, after said mobile terminal sends the position update information to said network server, said network server re-registers the update information of said mobile terminal.

    [0012] According to an embodiment, when said network server pages a mobile terminal, it pages the GSM of said mobile terminal.

    [0013] According to the embodiment of the present invention, if a mobile terminal is in the Packet Transfer state, the network server stops paging said mobile terminal until receiving position update information from said mobile terminal, and then pages said mobile terminal according to the new position information so as to send text messages. When a mobile terminal is switching in the Packet Transfer state, it can receive and send text messages promptly and rapidly, which ensures that users can receive text messages promptly and facilitates the promotion of the mobile terminals.

    [0014] The aforementioned characteristics, features and advantages of the invention as well as the way they are achieved will be further illustrated in connection with the following examples and considerations as discussed in view of the figures.

It should be understood that the specific embodiment described herein is only intended to explain the present invention, not to limit the present invention.

    [0016] Fig.1 illustrates the flow of the method for mobile terminals to receive text messages according to an embodiment of the present invention.

    [0017] In Step S101, a network server pages a mobile terminal and determines whether text messages can be sent; Wherein, when said network server pages a mobile terminal, it pages GSM of said mobile terminal.

    [0018] In Step S102, if said mobile terminal is in the Packet Transfer state, it does not respond to the paging by said network server.

    [0019] In Step S103, if said network server does not receive a response from said mobile terminal, it terminates the paging until receiving position update information from said mobile terminal.

    [0020] In Step S104, after updating the position, said mobile terminal sends position update information to said network server.

    [0021] In Step S105, said network server re-registers the update information of said mobile terminal.

    [0022] In Step S106, said network server continues to page said mobile terminal according to the position update information of said mobile terminal so as to take an action to send text messages.

    [0023] In Step S107, said mobile terminal responds to the paging by said network server and receives text messages sent by said network server.

    [0024] Fig.2 illustrates the structure of the mobile terminal network according to the embodiment of the present invention.

    [0025] Said network comprises a network server 11 and at least one mobile terminal 12, the network server 11 pages the mobile terminal 12 and determines whether text messages can be sent, if said mobile terminal 12 is in the Packet Transfer state, it does not respond to the paging by said network server 11; Wherein, when said network server 11 pages the mobile terminal 12, it pages the GSM of said mobile terminal.

    [0026] If said network server 11 does not receive a response from said mobile terminal, it terminates the paging until receiving position update information from said mobile terminal 12.

    [0027] After updating the position, said mobile terminal 12 sends position update information to said network server 11; after said mobile terminal 12 sends the position update information to said network server 11, said network server 11 re-registers the update information of said mobile terminal 12.

    [0028] Said network server 11 continues to page said mobile terminal 12 according to the position update information so as to take an action to send text messages. After said network server 11 continues to page said mobile terminal 12 according to the position update information, said mobile terminal 12 responds to the paging by said network server 11 and receives text messages sent by said network server 11.

    [0029] According to the embodiment of the present invention, if a mobile terminal is in the Packet Transfer state, the network server stops paging said mobile terminal until receiving position update information from said mobile terminal, and then pages said mobile terminal according to the new position information so as to send text messages. When a mobile terminal is switching in the Packet Transfer state, it can receive and send text messages promptly and rapidly, which ensures that users can receive text messages promptly and facilitates the promotion of the mobile terminals.

    [0030] It should be understood that those skilled in the art may make improvements or modifications according to the above description, while all these improvements and modifications shall be encompassed by the claims of the present invention.
