Embodiment 1

[0082] An embodiment of the present invention provides an ISR activation method, which includes the following steps: when the UE moves from the first access network to the second access network, the first mobility management unit corresponding to the first access network and The second mobility management unit corresponding to the second access network performs ISR activation according to the network capability and / or the local offload service information of the UE; wherein, the network capability includes: the capability of the mobility management unit to support serving gateway reselection in a non-mobile situation, And / or the ability of the mobility management unit and the serving gateway to support ISR; the UE's local offload service information includes: whether the UE is allowed to establish a local offload service and / or whether the UE has established a gateway-separated local offload service connection.

[0083] Preferably, in the embodiment of the present invention, th...

Embodiment 2

[0148] An embodiment of the present invention provides an ISR indication method, which includes the following steps: when the mobility management unit detects that a serving gateway is reselected for the UE and requires the UE to re-establish a connection, the mobility management unit instructs the UE to deactivate the ISR or deactivate the ISR .

[0149] Preferably, the situation of reselecting the serving gateway for the UE includes but is not limited to one of the following: 1) If the UE has established a gateway-separated local offload service connection, when the UE moves out of the local network, reselect the serving gateway for the UE; 2) If the UE has established a core network connection, when the UE establishes a gateway-separated local offload service connection, the serving gateway will be reselected for the UE; 3) If the serving gateway currently connected to the UE is not optimized enough, the serving gateway will be reselected for the UE .

[0150] Preferably, ...

Embodiment 3

[0186] The embodiment of the present invention provides a network capability indication method, including the following steps: in the mobility management process, the mobility management unit notifies the UE of the capability of the network to support serving gateway reselection in non-mobility conditions.

[0187] Preferably, before the mobility management unit notifies the UE of the capability of the network to support serving gateway reselection in a non-mobile situation, the method further includes: the mobility management unit determines that the network supports the ISR function.

[0188] Preferably, before the mobility management unit notifies the UE of the capability of the network to support serving gateway reselection under non-mobile conditions, the method further includes: the mobility management unit determines that the ISR needs to be activated currently.

[0189] The implementation method of acquiring network capabilities during the Attach / TAU / RAU process, the sp...

Abstract

Disclosed are ISR activation and deactivation methods. The ISR deactivation method comprises: a UE receiving a deactivation bearing request sent by a mobile management unit, the deactivation bearing request being used for requesting the UE to re-establish a connection; and if the UE has activated ISR, deactivating ISR when it is detected that a deactivation cause value is that a connection needs to be re-activated and / or the mobile management unit indicates that a network supports serving gateway reselection in a non-motion case. The present invention solves a problem that ISR states on a network side and a UE side are different, and removes a limitation "it is required that TA setting of a local network should be different from that of another network", thereby saving a network resource.

Description

technical field [0001] The present invention relates to the communication field, in particular to an ISR activation and deactivation method. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, 3GPP (3rd Generation Partnership Project , Third Generation Partnership Project) standard working group is working on the research of Evolved Packet System (EPS for short). figure 1 It is an architecture diagram of an evolved packet domain system according to related technologies, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The core network includes a Home Subscriber Server (HSS for short), a Mobility Management Entity (MME for short), a Serving GPR...
