Method and network device for creating and deleting resources
DCFirst Claim
1. A mobility management network device comprising:
- a receiver; and
a transmitter configured to communicatively connect with the receiver,wherein, during a handover from a non-3rd Generation Partnership Project (non-3GPP) access system to a 3GPP access system,the receiver is configured to receive, from a user equipment (UE), an access request message for access the 3GPP access system; and
the transmitter is configured to send a resource request message to a packet data network gateway (PDN GW) to create resources for the UE to be used in the 3GPP access system,wherein the access request message includes first handover indication information indicating that the access is a handover access;
wherein, in response to the first handover indication information being included in the access request message, the resource request message is configured to include second handover indication information, which indicates that the resource request message is caused by a handover access; and
wherein the second handover indication information is configured to be carried by an indication flag of the resource request message, the indication flag including one of a handover indication flag, a create type flag which is set to be handover create, and cause flag which is set to be handover cause.

Abstract
Embodiments of the present invention provide a method for creating resources, a method for deleting resources, and a network device. The method for creating resources includes: notifying, by a first network element, a second network element at network side of a process type for creating resources for a UE; and performing, by the second network element, a process for creating resources for the UE according to the process type. With the embodiments of the present invention, a problem in the prior art that the network element at network side (i.e., the second network element at network side) cannot differentiate different access requests (i.e., initial access request and access request caused by handover between access systems) and thus corresponding resources cannot be created with respect to different access requests may be overcome.

7. A method in a communication system, comprising:
-
during a handover of a user equipment (UE) from a non-3rd Generation Partnership Project (non-3GPP) access system to a 3GPP access system, receiving, by a mobility management network device from the UE, an access request message for access the 3GPP access system; and sending a resource request message from the mobility management network device to a packet data network gateway (PDN GW) to create resources for the UE to be used in the 3GPP access system, wherein the access request message includes first handover indication information indicating that the access is a handover access; wherein, in response to the first handover indication information being included in the access request message, the resource request message includes second handover indication information which indicates that the resource request message is caused by a handover access; and wherein the second handover indication information is carried by an indication flag the resource request message, the indication flag including one of a handover indication flag, a create type flag which is set to be handover create, and cause flag which is set to be handover cause. - View Dependent Claims (8, 9, 10, 11, 12)

13. A communication system comprising:
-
a mobility management network device configured to be responsible for mobility management, wherein, during a handover of a user equipment (UE) from a non-3rd Generation Partnership Project (non-3GPP) access system to a 3GPP access system, the mobility management network device is configured to; receive, from the UE, an access request message for access the 3GPP access system; and send a resource request message to a packet data network gateway (PDN GW) to request the PDG GW to create resources for the UE to be used in the 3GPP access system, wherein the access request message includes first handover indication information indicating that the access is a handover access; and wherein, in response to the first handover indication information being included in the access request message, the mobility management network device is configured to include second handover indication information indicating that the resource request message is caused by a handover access into the resource request message; and wherein the mobility management network device is configured to carry the second handover indication information by an indication flag of the resource request message, the indication flag including one of a handover indication flag, a create type flag which is set to be handover create, and cause flag which is set to be handover cause. - View Dependent Claims (14, 15, 16, 17, 18)
