1. A method, comprising:
- acquiring, by a network node of a source cell, information that a handover of a plurality user terminals currently connected to the source cell is needed to a target cell;
determining at least one attribute with respect to each of the plurality of user terminals;
selecting at least some of the plurality of user terminals to form a group of user terminals such that the user terminals in the group share at least one common attribute; and
indicating the at least one common attribute of the group to a target node of the target cell in a group handover request message.

Abstract
There is provided a method, including acquiring, by a network node of a source cell, information that a handover of a plurality user terminals currently connected to the source cell is needed to a target cell; determining at least one attribute with respect to each of the plurality of user terminals; selecting at least some of the plurality of user terminals to form a group of user terminals such that the user terminals in the group share at least one common attribute; and indicating the at least one common attribute of the group to a target node of the target cell in a group handover request message.

8. A method, comprising:
-
receiving, by a network node of a target cell, a group handover request message from a source node of a source cell, wherein the request message comprises an indication of at least one common attribute shared by a plurality of user terminals in a group which is to be handed over to the target cell;
considering the received at least one common attribute as valid for each of the user terminals in the group; andduring the transfer of the context of the individual user terminals in the group from the source node as part of a handover process, bypassing the re-reception of the at least one common attribute from the source node. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method, comprising:
-
receiving, by a user terminal comprised in a group which is to be handed over from a source cell to a target cell, an indication of a timing advance which is to be applied in a communication with the target cell; and detecting that a specific part of the handover process related to acquiring the timing advance is to be bypassed.

19. An apparatus, comprising:
-
at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to; acquire information that a handover of a plurality user terminals currently connected to a source cell is needed to a target cell; determine at least one attribute with respect to each of the plurality of user terminals; select at least some of the plurality of user terminals to form a group of user terminals such that the user terminals in the group share at least one common attribute; and indicate the at least one common attribute of the group to a target node of the target cell in a group handover request message. - View Dependent Claims (21, 23)
