EI signaling for group handover
According to certain embodiments, a method in a network node for performing a group handover comprises receiving an indication to perform a bearer context operation on a plurality of bearer contexts and performing the indicated bearer operation on the plurality of bearer contexts.
1 . A method for use in a network node for performing a group handover, the method comprising:
receiving an indication to perform a bearer context operation on a plurality of bearer contexts, wherein the indication to perform the bearer context operation on the plurality of bearer contexts comprises an indication to perform one of a bearer context modification request, bearer context release request, or bearer context setup request for the plurality of bearer contexts, where the plurality of bearer contexts are associated with a plurality of user equipments or integrated access and backhaul mobile terminals, and wherein receiving the indication comprises receiving a group command; and
performing the indicated bearer context operation on the plurality of bearer contexts.
2 . A network node operable to perform a group handover, the network node comprising processing circuitry operable to:
receive an indication to perform a bearer context operation on a plurality of bearer contexts, wherein the indication to perform the bearer context operation on the plurality of bearer contexts comprises an indication to perform one of a bearer context modification request, bearer context release request, or bearer context setup request for the plurality of bearer contexts, where the plurality of bearer contexts are associated with a plurality of user equipments or integrated access and backhaul mobile terminals, and wherein the processing circuitry is operable to receive the indication by receiving a group command; and
perform the indicated bearer context operation on the plurality of bearer contexts.
3 . The network node of claim 2 , wherein the indication incudes a list identifying the plurality of bearer contexts.
4 . The network node of claim 2 , wherein the indication includes a group identifier identifying the plurality of bearer contexts.
5 . The network node of claim 4 , wherein the indication further comprises a list identifying bearer contexts to exclude from the plurality of bearer contexts identified by the group identifier.
6 . The network node of claim 2 , wherein the indication comprises an identifier of an integrated access and backhaul (IAB) node and the plurality of bearer contexts comprise bearer contexts associated with the IAB node.
7 . The network node of claim 2 , wherein the network node comprises a source network node and the bearer context operation comprises at least one of a bearer context modification request and a bearer context release request.
8 . The network node of claim 2 , wherein the network node comprises a target network node and the bearer context operation comprises at least one of a bearer context modification request and a bearer context setup request.
9 . The network node of claim 2 , wherein the network node comprises a centralized unit (CU) user plane (UP), and the network node receives the indication from a centralized unit (CU) control plane (CP).
10 . The network node of claim 2 , wherein the plurality of bearer contexts are associated with at least one of a user equipment and an integrated access and backhaul (IAB) node mobile termination (MT).
11 . A method for use in a first network node for performing a group handover, the method comprising:
transmitting an indication to a second network node to perform a bearer context operation on a plurality of bearer contexts, wherein the indication to perform the bearer context operation on the plurality of bearer contexts comprises an indication to perform one of a bearer context modification request, bearer context release request, or bearer context setup request for the plurality of bearer contexts, where the plurality of bearer contexts are associated with a plurality of user equipments or integrated access and backhaul mobile terminals, and wherein transmitting the indication comprises transmitting a group command; and
receiving an indication of a result of the bearer context operation from the second network node.
12 . A network node operable to perform a group handover, the network node comprising processing circuitry operable to:
transmit an indication to a second network node to perform a bearer context operation on a plurality of bearer contexts, wherein the indication to perform the bearer context operation on the plurality of bearer contexts comprises an indication to perform one of a bearer context modification request, bearer context release request, or bearer context setup request for the plurality of bearer contexts, where the plurality of bearer contexts are associated with a plurality of user equipments or integrated access and backhaul mobile terminals, and wherein the processing circuitry is operable to transmit the indication by transmitting a group command; and
receive an indication of a result of the bearer context operation from the second network node.
13 . The network node of claim 12 , wherein the indication incudes a list identifying the plurality of bearer contexts.
14 . The network node of claim 12 , wherein the indication includes a group identifier identifying the plurality of bearer contexts.
15 . The network node of claim 14 , wherein the indication further comprises a list identifying bearer contexts to exclude from the plurality of bearer contexts identified by the group identifier.
16 . The network node of claim 12 , wherein the indication comprises an identifier of an integrated access and backhaul (IAB) node and the plurality of bearer contexts comprise bearer contexts associated with the IAB node.
17 . The network node of claim 12 , wherein the second network node comprises a source network node and the bearer context operation comprises at least one of a bearer context modification request and a bearer context release request.
18 . The network node of claim 12 , wherein the second network node comprises a target network node and the bearer context operation comprises at least one of a bearer context modification request and a bearer context setup request.
19 . The network node of claim 12 , wherein the first network node comprises a centralized unit (CU) control plane (CP), and the second network node comprises a centralized unit (CU) user plane (UP).
20 . The network node of claim 12 , wherein the plurality of bearer contexts are associated with at least one of a user equipment and an integrated access and backhaul (IAB) node mobile termination (MT).
