Abstract
A method and system for controlling signalling transmission in a power-saving mode are disclosed. The method includes that a terminal transmits a tracking area update request signalling or a routing area update request signalling to a new mobility management unit, wherein each signalling includes a power-saving parameter; and the new mobility management unit transmits a power-saving parameter to an old mobility management unit or a serving gateway. According to the disclosure, a network is enabled to keep pace with the power-saving mode of the terminal, and a paging message is transmitted only at activation time, thereby ensuring that the terminal may receive the paging message, and avoiding resource waste caused by repeated paging of the network.

A method for controlling signalling transmission in a power-saving mode, comprising:
- transmitting, by a terminal, a tracking area update (TAU) request signalling or a routing area update (RAU) request signalling to a new mobility management unit, wherein the TAU request signalling and the RAU request signalling each comprises a power-saving parameter;
- and
- transmitting, by the new mobility management unit, the power-saving parameter to an old mobility management unit or a serving gateway;
- wherein transmitting the power-saving parameter by the new mobility management unit to the old mobility management unit comprises:
- transmitting, by the new mobility management unit, a context request signalling to the old mobility management unit;
- transmitting, by the old mobility management unit, a context response signalling to the new mobility management unit, wherein the context response signalling comprises an Idle mode Signalling Reduction (ISR) mode supported indication;
- and
- transmitting, by the new mobility management unit, a context confirmation signalling to the old mobility management unit, wherein the context confirmation signalling comprises an ISR activation indication and the power-saving parameter.
A system for controlling signalling transmission in a power-saving mode, comprising a terminal, a new mobility management unit, an old mobility management unit and a serving gateway, wherein
- the terminal is configured to transmit a tracking area update (TAU) request signalling or routing area update (RAU) request signalling to the new mobility management unit, wherein the TAU request signalling and the RAU request signalling each comprises a power-saving parameter;
- the new mobility management unit is configured to transmit the power-saving parameter to the old mobility management unit or the serving gateway;
- and
- the old mobility management unit and the serving gateway save the power-saving parameter received;
- wherein
- the new mobility management unit is also configured to transmit a context request signalling to the old mobility management unit;
- the old mobility management unit is also configured to transmit a context response signalling to the new mobility management unit, wherein the context response signalling comprises an Idle mode Signalling Reduction (ISR) mode supported indication;
- and
- the new mobility management unit is also configured to transmit a context confirmation signalling to the old mobility management unit, wherein the context confirmation signalling comprises an ISR activation indication and the power-saving parameter.
