Problems solved by technology

[0033] 1. The correct uplink and downlink PDCH is not defined or the multi-slot capability of the terminal is violated;
[0034] 2. The terminal does not obtain enough effective PSI (packet system information) or SI (system information);
[0036] 4. Uplink Status Flag (USF) Scheduling Failed
Therefore, it is impossible to distinguish the handover failure caused by different failure reasons, which will affect the handover control of the network

Embodiment Construction

[0146] It can be seen from the background technology that the reasons for the handover failure include the following situations:

[0147] 1. The network does not define correct uplink and downlink PDCHs or violates the multi-slot capability of the terminal.

[0148] 2. The terminal does not obtain enough effective PSI or SI.

[0149] 3. The timer in the terminal times out.

[0150] 4. USF scheduling failed.

[0151] 5. The handover command contains an invalid frequency parameter IE; or the handover command contains a frequency that is not in the same frequency band; or the frequency parameter contained in the handover command is not supported by the IE terminal.

[0152] 6. Other undefined reasons leading to switching failure.

[0153] Among them, the reasons described in clauses 1 to 4 are the main reasons leading to the initial access failure in the handover failure. The reason described in Clause 5 is the main cause of the synchronization failure in the handover failure...

Abstract

A method for processing switch-failure in packet switching course confirms out different reason value by terminal according to different reason caused failure of switch when switch-failure is occurred in packet switching course of mobile communication.

Description

technical field [0001] The invention relates to the communication field, in particular to the packet switching technology. Background technique [0002] In the Packet Switched Domain (PS, Packet Switched Domain) of the Global System for Mobile Communication (GSM, Global System for Mobile Communication), the real-time packet service has strict quality of service (QoS, Quality of Service) on the jitter rate and packet loss rate. Therefore, the jitter rate and packet loss rate of real-time packet services are usually reduced by packet switching. [0003] The types of packet switching are different according to different division methods. According to the mode of the terminal (MS, MobileStation), packet switching can be divided into packet switching from A / Gb mode to A / Gb mode, packet switching from A / Gb mode to Iu mode, and packet switching from Iu mode to Iu mode; The packet handover can be divided into source base station subsystem (BSS, Base Station System) handover (Intra...
