Problems solved by technology

In summary, it can be seen that it is inappropriate to use the same processing method for the deregistration in the above scenario as the deregistration caused by the UE shutdown, and it cannot guarantee the correct progress of the ISR deactivation process.

Embodiment 1

[0053] In this embodiment, the UE that has activated the ISR has not performed a TAU or RAU to contact the network side for a long time, and the MME or the SGSN initiates the deregistration of the UE. In the following, the MME initiates deregistration of the UE as an example for description. The deregistration process initiated by the SGSN is similar to this process and will not be repeated here. Such as image 3 shown, including the following processing:

[0054] Step 301, the MME initiates the process of deregistering the UE. If the deregistration is caused by the UE not communicating with the network for a long time and the timer expires, the MME will not send a deregistration message to the UE; the MME will send the deregistration message to notify the UE of deregistration due to other reasons , and the message carries a deregistration type, and the deregistration type is used to notify the UE of subsequent operations.

[0055] In step 302, the MME sends a delete bearer...

Embodiment 2

[0067] In this embodiment, the HSS subscribes to restrict access to the EPS or GPRS network, causing the MME to initiate logout of the EPS network or the SGSN to log out of the GPRS network. In this scenario, the UE has activated the ISR. Such as Figure 4 shown, including the following processing:

[0068] In step 401, if the subscription data of the HSS changes and the UE is expected to be prohibited from using the EPS network, the HSS sends a location cancellation request to the MME, which carries the cancellation reason as subscription prohibition.

[0069] Step 402, if the reason for the location cancellation is subscription prohibition, the MME will send a deregistration request to the UE.

[0070] In step 403, the MME sends a bearer deletion request to the S-GW, which carries the TEID.

[0071] In step 404, the S-GW deletes the bearer context established with the MME, and sends back a delete bearer response to the MME.

[0072] Step 405, the MME sends an ISR deactiv...

Embodiment 3

[0082]The ISR deactivation method provided by the embodiment of the present invention is also applicable to the current deregistration process caused by the shutdown of the UE. Such as Figure 5 As shown, the deregistration process initiated by the shutdown of the ISR-activated UE to which the present invention is applied includes the following processing:

[0083] In step 501, the UE initiates a deregistration request, which carries GUTI and a Switch off indication, and the indication is used to indicate the reason for deregistration to the network.

[0084] In step 502, the MME sends a delete bearer request to the S-GW, which carries the TEID.

[0085] In step 503, the S-GW deletes the bearer context established with the MME, and sends back a delete bearer response to the MME.

[0086] Step 504: The MME sends an ISR deactivation notification message to the ISR-activated SGSN according to the originally stored UE-related information, which indicates that the deregistration ...

Abstract

The invention discloses an ISR deactivation method and an ISR deactivation indicating device, wherein the method comprises sending an ISR deactivation message to a corresponding core network node when the register state of a user device of a current core network node in a pair of core network nodes used for activating the ISR function changes, and indicating the corresponding core network node to conduct related operations, wherein the related operations comprise one of ISR deactivation, and ISR deactivation and loading deletion. In addition, the invention further discloses a mobility management entity and a service GPRS support node. Through the technical scheme, the process errors caused by the asynchronous ISR state can be prevented.

Description

technical field [0001] The present invention relates to the communication field, in particular to an ISR deactivation method, an ISR deactivation indicating device, a mobility management entity, and a serving GPRS support node. Background technique [0002] In order to maintain the competitiveness of the third generation mobile communication system in the communication field, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) standard working group is working on the research of EPS (Evolved Packet System, evolved packet domain system). EPS system such as figure 1 As shown, it mainly includes two parts: E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) and EPC (Evolved Packet Core, Evolved Packet Core Network). The EPC of the system can support user access from GERAN (GSM EDGE radio access network, GSM EDGE wireless access network) and UTRAN (Universal Terrestrial Radio Access Netwo...
