Problems solved by technology

[0007] As mentioned above, according to the existing handover process, only due to short-term link failures and other reasons, it is likely to cause multiple abnormal handovers between cells in a relatively short period of time, resulting in short-term signaling congestion and bringing The jitter of incoming services and the decline of user service experience

Embodiment 1

[0041] Embodiment 1. A grouping switching method, the process is as follows figure 1 shown, including:

[0042] A1. The mobile station sends the handover request containing the handover cause identifier to the source GANC or the source BSS;

[0043] The handover can be initiated by the mobile station, for example, the mobile station may find that the quality of the GAN link is degraded through local measurement, and thus send a handover request; the handover may also be initiated by the network side, for example, the source GANC or the source BSS finds that the uplink If there is a link quality failure or the load balancing strategy of the network operator, the mobile station is notified to perform handover through the link quality indication information, and the mobile station sends a handover request based on this information;

[0044] In order to achieve the purpose of accurately recording the reasons for the handover, the possible causes of the handover can be classified ...

Embodiment 2

[0074] Embodiment 2, a grouping switching method, the process is as follows image 3 shown, including:

[0075] B1. The mobile station initiates a handover from the source GAN cell or the source GERAN cell to the target GERAN cell or the target GAN cell, and sends the handover request to the source GANC or the source BSS; and records the handover cause identification corresponding to the handover reason, as in the first embodiment Similarly, the handover reason identification can be obtained by classifying and numbering the actual handover reason;

[0076] B2. The mobile station judges whether the handover cause corresponding to the handover cause identifier still exists during the subsequent handover operation, and if so, continues to perform the subsequent handover operation, otherwise cancels the handover;

[0077] According to the existing handover process, the subsequent handover operations that the mobile station may perform include:

[0078] Receive the switching comm...

Embodiment 3

[0097] Embodiment 3, a grouping switching method, the process is as follows Figure 5 shown, including:

[0098] C1. After the mobile station switches to the current source GAN cell or the source GERAN cell, it starts the switch timer;

[0099] C2. The mobile station determines in the current cell that a new handover needs to be initiated;

[0100] C3. The mobile station judges whether the handover timer is timed out, and if so, initiates the handover, and otherwise prohibits the initiation of the handover.

[0101] In the above method, a typical situation is that the mobile station is currently located in a GERAN cell, and the target cell for initiating a new handover is a GAN cell; at this time, as a better method, the mobile station prohibits the initiation of handover, which can be done by The method of excluding the target GAN cell from the measurement report reported to the source BSS, so that the measurement report will not trigger the handover process to the GAN cell...

Abstract

The invention discloses a grouping switch method which essentially means that a judgment step on executing a switch condition is added to a switch process and the current switch initiating or executing is controlled via a pre-placed switch condition. The judgment step may be carried out at any time before the completion of a switch by any related node of the switch like a mobile station, a base station controller or a universal access network controller, etc. The invention avoids an unusual backward and forward switch between the cells according to the judgment of unusual performance by the pre-placed switch condition, and reduces the signaling flow, thereby improving the stability of the service.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a packet switching method and communication equipment. The packet switching method is especially suitable for packet switching between a general access network and a wireless 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 ...
