Abstract

The present invention relates to the field of paging terminals within a communication network. In order to contact a group of terminals, a common group identification is allocated to each of the terminals within said group. Thereafter, a paging message is created comprising said common group identification. The paging message is then transmitted to all terminals within said group by a single paging operation.

Claims

1. A method for contacting a group of terminals within a communication network, said group comprising at least two terminals, the method comprising:

allocating a common group identification to each of the terminals within said group;

creating a paging message comprising said group identification; and

transmitting the paging message to all terminals within said group by a single paging operation;

wherein creating the paging message comprises including a parameter indicating a timing of when accesses in response to the paging should be sent.

2. The method of claim 1, whereby said common group identification is a specific International Mobile Subscriber Identity for the group.

3. The method of claim 1, whereby said common group identification is a Temporary Mobile Group Identity.

4. The method of claim 1, whereby said common group identification is a mobile identity having the value “

no identity”

.

5. The method of claim 1, wherein transmitting the paging message by a single paging operation comprises sending a single paging message.

6. The method of claim 1, wherein the method is performed in a node of the communication network.

7. The method of claim 1, further comprising receiving a response from at least one of said terminals.

8. The method of claim 7, wherein receiving a response comprises receiving a report from said at least one of said terminals.

9. The method of claim 1, further comprising transmitting information for the purpose of updating, or reconfiguration, or both, to at least one of said terminals.

10. The method of claim 1, whereby the paging message comprises additional information comprising one of more of:

an indication of a requested response by the terminals,

one or more parameters related to a requested response by the terminals,

an indication of a type of page,

an indication of how required access by the terminals to the communication network should be performed,

one or more parameters related to a required access by the terminals to the communication network,

an indication of a particular sub-group of terminals to which the joint page is addressed, and

one or more specific commands or instructions intended for the terminals.

11. A method in a terminal for a communication network, the terminal belonging to a group of terminals comprising at least two terminals, the method comprising:

being allocated a common group identification similar for all devices within said group;

receiving a paging message comprising said common group identification, the paging message comprising a parameter indicating a timing of when accesses in response to the paging should be sent by the terminal; and

transmitting a response to said paging message, wherein transmitting the response comprises delaying the transmission of said response by determining a random period of delay time depending on the received parameter and delaying the transmission of said response by the determined period of delay time.

12. The method of claim 11, wherein transmitting a response to said paging message comprises transmitting a report.

13. The method of claim 11, wherein said method further comprises receiving information for updating said terminal or reconfiguring said terminal, or both.

14. An apparatus for contacting a group of terminals for a communication network, said group comprising at least two terminals, the apparatus comprising:

a processing circuit adapted to associate each terminal within the group of terminals with a common group identification and to create a paging message that includes said common group identification; and

a transmitter adapted to transmit the paging message to each of the terminals within said group;

wherein the processing circuit is adapted to include, in the paging message, a parameter indicating a timing of when accesses in response to the paging should be sent.

15. An apparatus according to claim 14, wherein the processing circuit is part of a network controller or a system server.

16. A terminal for a communication network belonging to a group of terminals comprising at least two terminals, the terminal comprising:

a receiver adapted to receive a paging message;

transmitter circuitry adapted to transmit a response to said paging message; and

a delay circuit adapted to delay the transmission of said response.

17. A terminal according to claim 16, wherein the transmitter circuitry is adapted to receive a parameter indicating a timing of when accesses in response to the paging should be sent by the terminal, as additional information in the paging message, and wherein the delay circuit is adapted to determine a random delay time period that depends on the received parameter, and to delay the transmission of said response with the determined random delay time period.
