Abstract: Systems and methods are disclosed for providing an enhanced Packet Forwarding Control Protocol (PFCP) association procedure for session restoration. In this regard, a method performed by a PFCP node comprises deleting one or more PFCP sessions of the PFCP node that are associated with a failed PFCP entity or with a failed PFCP path. The method further comprises sending, to a PFCP peer node, a node level message to request that the PFCP peer node delete a corresponding one or more PFCP sessions of the PFCP peer node that are associated with the failed PFCP entity or with the failed PFCP path, wherein the node level message comprises an indication of the corresponding one or more PFCP sessions. Some embodiments provide that the node level message comprises a PFCP Association Setup Request including sessions retention information to indicate whether to retain PFCP sessions associated with the PFCP Association Setup Request.

Abstract: A method for a target mobility management entity and a target mobility management entity for executing the method in a core network to communicate network function (NF) utilization information with a source mobility management entity during a change of mobility management entity are disclosed. The method comprises: receiving at least one old NF identifier (ID) from the source mobility management entity that corresponds to an old NF entity serving a user equipment (UE); determining to either use the at least one old NF ID or to use at least one new NF ID that corresponds to a new NF entity of a same NF type as the old NF entity; and communicating, to the source mobility management entity, information that indicates to the source mobility management entity whether the target mobility management entity uses the at least one old NF ID or uses the at least one new NF ID.

Abstract: The invention relates to mobility management nodes and methods of the mobility management nodes of enabling delivery of a Mobile Terminating, (MT) Short Message (SM) to a mobile terminal.
In a first aspect of the invention, a method of a mobility management node is provided for enabling delivery of a Mobile Terminating, (MT) Short Message (SM) to a mobile terminal which currently is in extended idle mode discontinuous reception, eDRX, mode. The method comprises receiving an indication from a Short Message Service Gateway Mobile Switching Centre (SMS-GMSC) that the SM is to be delivered, receiving a notification that the mobile terminal has exited an extended idle Discontinuous Reception (eDRX) mode before a paging occasion has occurred, and submitting, in response to the notification, a message indicating to the SMS-GMSC that the mobile terminal is available for delivery of the SM.-

Abstract: The embodiments herein relate to a method performed by a Control Plane (CP) function (401) for handling a credit pool comprising granted service units to be used by multiple services. The multiple services are grouped in at least one first Rating Group (RG). The CP function (401) creates an individual Usage Reporting Rule (URR) for each of the at least one first RG. Each individual URR comprises a first credit pool threshold. The CP function provides the individual URRs to a User Plane (UP) function (405). The CP function (401) creates a Usage Reporting Rule for the Credit Pool (URR CRPL). The URR CRPL comprises instructions to the UP function (405) to aggregate service unit usage for all individual URRs for all first RGs. The URR CRPL further comprises the first credit pool threshold. The CP function (401) provides the URR CRPL to the UP function (405).

Abstract: The embodiments herein relate to a method in a first mobility management node (108a) for handling updated subscriber data associated with a UE (101). The UE (101) is currently unreachable by the first mobility management node (108a). The first mobility management node (108a) receives, from a subscriber database (128), updated subscriber data associated with the UE (101). At least part of the updated subscriber data is modified. The first mobility management node (108a) determines that transmission of the updated subscriber data to a gateway node (110) should be postponed until the UE (101) has become reachable.

Abstract: The embodiments herein relate to a method performed by a gateway (108, 110, 1308, 1310). The gateway (108, 110, 1308, 1310) detects that a procedure for activating or deactivating a bearer has been initiated. The gateway (108, 110, 1308, 1310) receives a first modify bearer or modify access bearers request message for the same PDN connection and UE (101) as the bearer activation or deactivation procedure is intended for. The gateway (108, 110, 1308, 1310) detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway (108, 110, 1308, 1310) and associated with said same PDN connection and UE (101). The gateway (108, 110, 1308, 1310) accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.
