Abstract
A method and system for processing signaling release indication cause between user equipment and a wireless network, the method comprising the steps of: monitoring, at the user equipment, whether a signaling connection release indication should be sent to the wireless network; appending, at the user equipment, a cause for the signaling connection release indication to the signaling connection release indication; sending the appended signaling connection release indication to the wireless network; receiving the signaling connection release indication at the wireless network; and filtering said cause to determine whether to raise an alarm.
Claims20
A method for processing signaling release indication cause at a wireless network, comprising the steps of:
- receiving, from a user equipment, a signaling connection release indication at the wireless network, the signaling connection release indication including a cause for the signaling connection release indication, wherein the cause is set to “UE Requested PS Data session end”;
- and
- in response to determining that said cause included in the received signaling connection release indication is indicative of a radio resource control (RRC) state or mode transition request, processing, at the wireless network, the received signaling connection release indication.
A system configured for processing signaling release indication cause, the system comprising:
- a user equipment, the user equipment having a radio subsystem including a radio adapted to communicate with a wireless network;
- a radio processor having a digital signal processor and adapted to interact with said radio subsystem;
- a memory;
- a user interface;
- a processor adapted to run user applications and interact with the memory, the radio and the user interface and adapted to run applications, the user equipment configured to:
- monitor whether a signaling connection release indication should be sent to the wireless network;
- append a cause for the signaling connection release indication to the signaling connection release indication, wherein the cause is set to “UE Requested PS Data session end”;
- and
- send the appended signaling connection release indication to the wireless network;
- and
- the wireless network adapted to communicate with the user equipment and further configured to:
- receive the signaling connection release indication;
- and
- in response to determining that said cause in the received signaling connection release indication is indicative of an RRC state or mode transition request, process, at the wireless network, the received signaling connection release indication.
A method for processing signaling release indication cause at a user equipment, comprising the steps of:
- monitoring whether a signaling connection release indication should be sent to a wireless network;
- appending a cause for the signaling connection release indication to the signaling connection release indication, wherein the cause is set to “UE Requested PS Data session end”;
- and
- sending, to the wireless network, the appended signaling connection release indication to which the cause is appended, wherein the sending causes the wireless network to process the signaling connection release indication if said cause in the signaling connection release indication is indicative of an RRC state or mode transition request.
A user equipment configured for providing signaling release indication cause in a wireless network, the user equipment having a radio subsystem including a radio adapted to communicate with the wireless network;
- a radio processor having a digital signal processor and adapted to interact with said radio subsystem;
- a memory;
- a user interface;
- a processor adapted to run user applications and interact with the memory, the radio and the user interface and adapted to run applications, the user equipment configured to:
- monitor whether a signaling connection release indication should be sent to the wireless network;
- append a cause for the signaling connection release indication to the signaling connection release indication, wherein the cause is set to “UE Requested PS Data session end”;
- and
- send, to the wireless network, the appended signaling connection release indication that includes the cause, wherein sending the signaling connection release indication causes the wireless network to process the signaling connection release indication if said cause in the signaling connection release indication is indicative of an RRC state or mode transition request.
An apparatus for a user equipment to facilitate release of signaling connection, said apparatus comprising one or more hardware processors configured to:
- determine whether a signaling connection release indication should be sent;
- and
- send, to a wireless network, a signaling connection release indication responsive to determining that the signaling connection release indication should be sent, the signaling connection release indication including a signaling release indication cause field, the signaling release indication cause field being set to “UE Requested PS Data session end”, wherein sending the signaling connection release indication causes the wireless network to process the signaling connection release indication if said signaling release indication cause field in the signaling connection release indication indicative of an RRC state or mode transition request.
