Abstract

A method for registration-less paging includes establishing a mobile device identity for a mobile device in a wireless network, determining a time instance for the identified mobile device to listen to pages, and sending a page from the wireless network to the identified mobile device during the determined time instance. In one example, the method is for a network-initiated attach procedure and includes receiving a request to attach a mobile device in a wireless network, generating a paging message based on the request to attach the mobile device, sending a paging indicator to a mobile device based on the paging message during a time instance based on an agreed rule, and accepting an attach procedure from the mobile device based on the paging indicator.

15. An apparatus for registration-less paging by a mobile device in a wireless network, the method comprising:

means for determining, based on a mobile device identity, a time instance for the mobile device to listen to pages, the mobile device identity established during a first contact between the mobile device and the wireless network, the mobile device having been disconnected and de-registered from the wireless network after the first contact;

means for listening for a registration-less page from the wireless network during the determined time instance; and

means for initiating attachment of the mobile device when the registration-less page is received from the wireless network during the determined time instance.

16. The apparatus of claim 15, further comprising means for establishing the mobile device identity by performing a registration and setting up a connection for the mobile device during the first contact.

17. The apparatus of claim 16, further comprising means for indicating that the mobile device can use a new paging mechanism.

18. The apparatus of claim 15, wherein the mobile device identity is a long term ID (LTID).

19. The apparatus of claim 18, wherein the time instance is a function of the LTD.

20. The apparatus of claim 15, wherein the registration-less page further comprising paging data.

21. The apparatus of claim 20, wherein the paging data comprises one or more of the following:

user data or a special data which triggers at least one further action.

22. The apparatus of claim 21, wherein the special data is a command for the means for initiating attachment of the mobile device to initiate an attachment procedure.

23. An apparatus for performing a network-initiated attach procedure, the apparatus comprising:

means for receiving a request to attach a mobile device in a wireless network;

means for generating a registration-less paging message based on the request to attach the mobile device, the registration-less paging message including a paging indicator comprising user data or special data for triggering further action by the mobile device;
