Abstract
According to an aspect, a user equipment, UE, in a suspended state in a Radio Access Network, RAN, in response to expiration of a first timer, transmits an RRCResumeRequest message. The UE receives a reject message in response to the RRCResumeRequest message. In response to the reject message, the UE starts a second timer and subsequently transmits a further RRCResumeRequest message. The further RRCResumeRequest message is received by the network during a period bounded approximately by the lesser of a duration of the second timer and a period of the periodic UE event and the greater of the duration of the second timer and the period of the periodic UE event.
Claims18
A method of operating a user equipment (UE) in a suspended state in a radio access network (RAN) the method comprising:
- in response to expiration of a first timer, transmitting an RRCResumeRequest message;
- receiving, in response to the RRCResumeRequest message, a reject message;
- in response to the reject message, starting a second timer;
- and
- subsequently transmitting a further RRCResumeRequest message, in response to one of:
- expiration of a re-started first timer;
- expiration of the second timer;
- cell reselection;
- and
- availability of data for transmission.
A wireless device configurable for operating in a suspended state in a radio access network (RAN) the wireless device comprising:
- radio front-end circuitry;
- and
- processing circuitry operably coupled to the radio front-end circuitry and configured to use the radio front-end circuitry to:
- in response to expiration of a first timer, transmit an RRCResumeRequest message;
- receive, in response to the RRCResumeRequest message, a reject message;
- in response to the reject message, starting a second timer;
- and
- subsequently transmit a further RRCResumeRequest message in response to one of:
- expiration of a re-started first timer;
- expiration of the second timer;
- cell reselection;
- and
- availability of data for transmission.
