Embodiment 1

[0099] In this embodiment, when the UE initiates offline detachment from the eHRPD network, it carries a special instruction from the network layer to notify the network side to release all PDN connections and the optimized detachment method for their resources. For details, see Figure 4 And the following steps are analyzed:

[0100] 1. The UE decides to initiate a detach from the eHRPD network.

[0101] 2. The UE sends a VSNCP Terminate-Request (VSNCP Terminate-Request) signaling to the HSGW. The request carries a "detach" indication to notify the HSGW that all PDN connections, resources, and contexts need to be released, instead of releasing a certain PDN connection separately.

[0102] The detach indication can be a newly defined identification parameter, or it can be a new value defined by the existing parameter PDN-ID, that is, to escape the PDN-ID, and the HSGW needs to be able to parse out that the UE’s intention is to detach rather than delete a certain parameter. A PDN con...

Embodiment 2

[0114] In this embodiment, when the UE initiates offline detachment from the eHRPD network, it does not carry a special instruction from the network layer to notify the network side to release all PDN connections and their resources. For details, see Figure 5 And the following steps analysis:

[0115] 1. The UE decides to initiate a detach from the eHRPD network.

[0116] 2. The UE sends a VSNCP Terminate-Request (VSNCP Terminate-Request) signaling to the HSGW. The request does not carry the PDN-ID, because in the existing operation, each VSNCP termination request signaling carries the PDN-ID, indicating which PDN connection service the signaling is for. Now the signaling does not carry any PDN -ID, HSGW can resolve that the signaling serves all PDN connections, and all PDN connections, resources, and contexts need to be released, instead of releasing a certain PDN connection separately.

[0117] 3. The HSGW receives the VSNCP termination request signaling. According to the reques...

Embodiment 3

[0126] This embodiment is an optimization method for the UE to notify the network from the link layer to release all PDN connections and their resources when the UE initiates an offline detach from the eHRPD network. For details, see Image 6 And the following steps analysis:

[0127] 1. The UE decides to initiate a detach from the eHRPD network.

[0128] 2. The UE sends LCP Terminate-Request (LCP Terminate-Request) signaling to the HSGW.

[0129] Because the LCP session serves all PDN connections, as long as the HSGW receives the LCP termination request, it will release all PDN connections, resources, and contexts instead of releasing a single PDN connection.

[0130] 3. The HSGW receives the LCP termination request signaling. According to the request signaling, it resolves to release all PDN connections of the UE, and sends LCP Terminate-Ack signaling to the UE to notify the UE that it has received the request to detach Signaling.

[0131] 4. The HSGW sends a PBU (Lifetime=0 (zero l...

Abstract

The invention discloses an optimization method and an optimization system for to-adhering of a terminal from a network side, and an access gateway. The optimization method comprises the following steps that: the terminal transmits a request signaling for requesting to adhere to the access gateway, wherein the request signaling is a terminate-request signaling of a network layer or a terminate-request signaling of a link layer; and the access gateway releases information and resources of all public data network (PDN) connections of the terminal at the network side. By the invention, when the terminal transmits the request signaling once, the operation of releasing a plurality of PDN connections can be realized; therefore, when the terminal is to adhere, the steps can be uniformed, the time and the signaling can be saved and the system burden can be relieved.
