Abstract
A user equipment for handling an attach procedure with a service network is provided. The user equipment comprises a wireless module transmitting an attach request message to the service network and receiving an attach accept message replied to the attach request message from the service network, and a controller determining whether to accept the attach accept message, sending an attach complete message, via the wireless module, to the service network in response to the attach accept message being accepted, and resending the attach request message, via the wireless module, to the service network in response to the attach accept message not being accepted.
Claims20
A user equipment, handling an attach procedure with a service network, comprising:
- a wireless module transmitting an attach request message to the service network and receiving an attach accept message replied to the attach request message from the service network;
- and
- a controller determining whether to accept the attach accept message, sending an attach complete message, via the wireless module, to the service network in response to the attach accept message being accepted, and resending the attach request message, via the wireless module, to the service network in response to the attach accept message not being accepted.
A method for a user equipment to handle an attach procedure with a service network, comprising:
- sending an attach request message to the service network;
- receiving an attach accept message replied to the attach request message from the service network;
- determining whether to accept the attach accept message;
- sending an attach complete message to the service network in response to the attach accept message being accepted;
- and
- resending the attach request message to the service network in response to the attach accept message not being accepted.
A service network, handling an attach procedure with a user equipment, comprising:
- a radio access network receiving an attach request message from the user equipment, sending a first attach accept message to the user equipment in response to the attach request message, and receiving a response message from the user equipment;
- and
- a control node determining that the attach procedure has ended successfully in response to the response message being an attach complete message, aborting the attach procedure and initiating a new attach procedure by sending a second attach accept message, via the radio access network, to the user equipment in response to the response message being the attach request message resent by the user equipment, and aborting the attach procedure and sending a detach accept message, via the radio access network, to the user equipment in response to the response message being a detach request message.
A method for a service network to handle an attach procedure with a user equipment, comprising:
- receiving an attach request message from the user equipment;
- sending a first attach accept message to the user equipment in response to the attach request message;
- receiving a response message from the user equipment;
- determining that the attach procedure has ended successfully in response to the response message being an attach complete message;
- aborting the attach procedure and initiating a new attach procedure by sending a second attach accept message to the user equipment in response to the response message being the attach request message resent by the user equipment;
- and
- aborting the attach procedure and sending a detach accept message to the user equipment in response to the response message being a detach request message.
A mobile communication system, handling an attach procedure, comprising:
- a user equipment sending an attach request message, receiving a first attach accept message replied to the attach request message, determining whether to accept the first attach accept message, sending an attach complete message in response to the first attach accept message being accepted, and resending the attach request message in response to the first attach accept message not being accepted;
- and
- a service network receiving the attach request message, sending the first attach accept message to the user equipment in response to the attach request message, determining that the attach procedure has ended successfully upon receiving the attach complete message, and aborting the attach procedure and initiating a new attach procedure by sending a second attach accept message to the user equipment upon receiving the attach request message resent by the user equipment.
