Problems solved by technology

[0015] During the creation process of the present invention, the inventor found that at least the following problems existed in the prior art: in GAN, there is no logical association between the existing packet transmission channel switching process and the monitoring of the packet transmission channel
This leads to the possibility that the terminal may fail to handover and needs to return to the source GAN cell, but the packet channel timer used to monitor the packet transmission channel has timed out and triggers the packet channel release process between the terminal and the GANC , the packet channel between the terminal and the source GANC is no longer available and needs to be reactivated, resulting in certain service jitter

Embodiment 1

[0036] Embodiment 1. A monitoring method during packet transmission channel switching. This embodiment involves the switching of a terminal from a source GAN cell to another cell using a radio access technology (RAT, Radio Access Technology), and the terminal and the network There are packet services, and the RAT can be GERAN, UTRAN or GAN. The method flow is as follows figure 2 shown, including:

[0037] A1. The terminal judges that it is in the process of switching the packet transmission channel of the source GAN cell;

[0038] In GAN, the switch of the packet transmission channel leaving the source GAN cell can be initiated by the GANC or the terminal. In this embodiment, the following specific triggering methods are given. Under different triggering methods, the terminal can make a packet transmission according to the corresponding information. Judgment of the channel switching process:

[0039] 1. Switching is triggered by the terminal. The terminal finds that the q...

Embodiment 2

[0049] Embodiment 2. A monitoring method during packet transmission channel switching. This embodiment involves packet transmission channel switching of a terminal from a source GAN cell to a target RAT cell. The main difference between this embodiment and Embodiment 1 is that the execution of the release protection operation is triggered by the source GANC. The method flow is as follows image 3 shown, including:

[0050] B1. The source GANC judges that a certain terminal is in the process of switching out the packet transmission channel of the cell;

[0051] Under different packet transmission channel switching trigger modes, the source GANC can make a judgment that the terminal is in the packet transmission channel switching process according to the corresponding information. For example, in the first way listed in the first embodiment, the source GANC can determine that the relevant terminal is in the handover process based on receiving the handover reference message or ...

Embodiment 3

[0057] Embodiment 3. A monitoring method during packet transmission channel switching. This embodiment involves packet transmission channel switching of a terminal from a source GAN cell to a target RAT cell. The difference between this embodiment and Embodiment 1 is that another specific manner for the terminal to perform the release protection operation is provided. The method flow is as follows Figure 4 shown, including:

[0058] C1. The terminal judges that it is in the process of switching the packet transmission channel of the source GAN cell;

[0059] For a specific judgment method, reference may be made to the situation listed in Embodiment 1.

[0060] C2. The terminal triggers the release protection operation of the occupied packet transmission channel in the general access network, that is, monitors the operation of the packet channel timer, restarts the packet channel timer after the packet channel timer expires, and does not trigger packet transmission The rele...

Abstract

The invention discloses a method for monitoring packet transmission channel in the switching process between access network sub-districts and other sub-districts using random access techniques. In the packet transmission channel switch process, the terminal or universal access network controller triggers the releasing protection operations to packet transmission channel, thereby avoiding the release of packet transmission channel. The invention also discloses the corresponding terminal and universal access network controller. Since the invention logically links together the packet transmission channel switch process and the monitoring of the packet transmission channel, the packet transmission channel will not release beforehand in the switching process, and the terminal can smoothly and timely come back in the source sub-district for avoiding service jitter when abnormity occurs in the switching process.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a monitoring method in the switching process of a packet transmission channel related to a universal access network, a corresponding terminal and a controller of the universal access network. Background technique [0002] In the mobile communication network, the access network acts as a bridge between the terminal user and the core switching network, and its communication capability directly affects the user's experience of mobile services. With the continuous development of short-distance wireless communication technology, it has attracted more and more attention due to its advantages of high access bandwidth and low communication cost. The way of providing wireless access based on short-distance wireless communication technology in the license-free frequency band is rapidly popularizing, and it coexists with traditional wireless access networks in the local area or...
