Embodiment Construction

[0043] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0044] Such as figure 1 As shown, the embodiment of the present invention provides a kind of synchronization method of PDP (packet message protocol) state, comprises the steps:

[0045] Step 11, receiving a service request sent by the terminal, wherein the service request carries the PDP status of the terminal;

[0046] Step 12, judging whether the PDP state in the service request is an active state, if so, directly establishing a bearer RAB connection of the user plane;

[0047] Step 13, if the PDP state in the service request is a deactivated state, and the PDP state locally saved by the network side device is an activated state, then synchronize the locally saved PDP state with the PDP state of the terminal, so that the locally saved PDP state is act...

Abstract

The invention provides a method for synchronizing a PDP state and a network side device. The method includes the steps that a service request sent by a terminal is received, wherein the service request carries the PDP state of the terminal; whether the PDP state in the service request is an activated state or not is judged and if yes, RAB connection of a user plane is directly established; if the PDP state in the service request is a deactivated state and a PDP state locally stored in the network side device is the activated state, the PDP state locally stored is synchronized to the PDP state of the terminal, and the PDP state locally stored and the PDP state of the terminal are identical. According to the scheme, the problem that RAB connection establishment fails due to non-synchronization of the PDP states of the terminal and a core network side can be solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a PDP state synchronization method and network side equipment. Background technique [0002] With the development of 3G networks and the increasing popularity of smart terminals, users are more and more aware of the convenience brought by high-speed Internet access on 3G networks, and PS (packet) services have increased sharply. The problem caused many problems in PS services, which affected network performance and user perception. [0003] Due to various reasons, the PDP status of the terminal and the core network may not be synchronized. For example, the terminal suddenly loses power, and the PDP status will disappear; If there is no response due to the reason, if there is still no response after 4 retries, the current PDP data will be deleted (see 6.1.3.4.3 of 3GPP TS24.008 for details). When these situations occur, the terminal will be in the inactive state (Inactive ...
