Embodiment 1

[0050] An embodiment of the present invention provides a signaling saving activation control method in idle mode, Figure 4 It is a flowchart of a signaling saving activation control method in idle mode according to Embodiment 1 of the present invention, as shown in Figure 4 As shown, the method includes:

[0051] 402. The user equipment UE performs joint tracking area update TAU and location area update LAU (also referred to as joint TAU / LAU in related technologies);

[0052] 404. Deactivate the ISR or keep the ISR inactive if the predetermined condition is met, where the predetermined condition includes: the result of the combined TAU and LAU is that only the combined TAU and LAU of SMS over SGs is successful, and the UE needs to support a predetermined service, and the predetermined Services include: other CS services except short message services. If the current ISR is active, deactivate the ISR if the predetermined condition is met; if the current ISR is inactive, keep...

Embodiment 2

[0056] In this embodiment, the UE needing to support predetermined services involved in the first embodiment specifically includes: UE needs to support predetermined services when accessing GERAN and / or UTRAN (also referred to as GERAN / UTRAN in related technologies). That is to say, when combining TAU / LAU, if only the joint update of SMS over SGs is successful, and the UE needs to support services such as CS voice calls when accessing GERAN / UTRAN, then ISR will not be activated.

[0057] Figure 5 It is a flowchart of a signaling saving activation control method in idle mode according to Embodiment 2 of the present invention, as shown in Figure 5 As shown, the method in this embodiment includes:

[0058] 502. The UE performs joint TAU / LAU in the E-UTRAN.

[0059] 504. The UE that needs to support services such as CS voice calls when accessing GERAN / UTRAN only succeeds in jointly updating SMS over SGs, so even if other conditions for ISR activation are met, the ISR is not ac...

Embodiment 3

[0062] On the basis of Embodiment 1 or Embodiment 2, this embodiment describes that when a predetermined condition is met, before deciding to deactivate the ISR or keep the ISR inactive, the method may further include: the predetermined network element determines that the UE needs to support A subscription service, wherein the subscription network element includes at least one of the following: UE, MME. The predetermined network element mentioned above (also referred to as the network element for judging and deciding on ISR activation) may be UE or MME. In actual implementation, based on the consideration of various network deployments, it may be MME and / or UE. judge.

[0063] It should be noted that the network element that determines that the UE needs to support the scheduled service is not limited to the UE and / or the MME, however, considering the source of the basis for determining that the UE needs to support the scheduled service, at least one of these two network elemen...

Abstract

The invention discloses a method and system for controlling the activation of ISR (Idle mode Signaling Reduction) and UE (user equipment). The method comprises the following steps of: carrying out the combination of TAU (Tracking Area Update) and LAU (Location Area Update) by the UE; activating the ISR or keeping the ISR not activated under the condition of meeting preset conditions, wherein the preset conditions include: the result of the combination of TAU and LAU is as follows: only the combination of TAU and LAU of SMS (Short Message Service) over SGs (Serving Gateways) succeeds, and the UE needs to support a preset service; and the preset service comprises other CS (Circuit Switching) services except for the SMS. The invention ensures that the UE can be called when the CS services such as speech calling and the like are carried out.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a signaling saving (Idle mode Signaling Reduction, ISR for short) activation control method, system and user equipment (User Equipment, UE for short) in idle mode. Background technique [0002] The standardization working group of the 3rd Generation Partnership Project is currently working on the research on the packet switching core network (Packet Switched Core, referred to as PS Core) and the Global Mobile Communication System Radio Access Network (Universal Mobile Telecommunication System RadioAccess Network, referred to as UTRAN) The evolved mobile communication system is called an evolved packet domain system (Evolved Packet System, EPS for short). [0003] figure 1 It is a network architecture schematic diagram of Global System for Mobile communications (GSM for short) / Universal Mobile Telecommunications System (UMTS for short) and EPS network based on related techn...
