  • Patent number: 10200908
    Abstract: Methods, apparatuses, system and computer program product for activation and/or deactivation of bearers for a group of devices are disclosed. The method comprises receiving an attach request for a device belonging to a group of devices, obtaining an identity of the group of devices, allocating a first bearer identity for the group of devices, and sending the identity of the group and the first bearer identity to a first network element, wherein the first network element is involved in transmission of user data of the group of devices.

  • Patent number: 8909260
    Abstract: A method includes transmitting a paging indicator indicating to user equipment assigned to one or more groups that the user equipment are to attempt to receive paging messages including paging information targeted to at least one of the one or more groups; and transmitting in a channel the paging information in the paging messages. Another method includes receiving a paging indicator indicating a user equipment is to attempt to receive paging messages including paging information targeted to at least one of one or more groups; and receiving from a channel the paging information in the paging messages. A method includes sending a request message to user equipment assigned to one or more groups, the request message comprising an indication to cause the user equipment to read device trigger information in a system broadcast message; and sending the device trigger information in the system broadcast message.

  • Publication number: 20140221025
    Abstract: The interaction between group paging and service requests can be enhanced through the appropriate use of a shared identifier and user equipment strategies for reacting when paged. These enhancements may be broadly applicable to many communication systems, such as evolved packet system (EPS) as well as general packet radio service (GPRS)/universal mobile telecommunications system (UMTS) networks. For example, a method according to certain embodiments can include preparing a response including a group shared unique identifier upon receiving an attach request or a tracking area update request. The method can also include sending the response to a user equipment in an attach accept or tracking area update accept message.
