Embodiment Construction

[0032] First of all, the radio access network of the cellular wireless communication system in the method of the present invention is described to distinguish between handover access and other random access methods:

[0033] (1) Part of the reserved feature codes, that is, the reserved feature codes, are allocated separately to mobile terminals requiring handover access, and other mobile terminals of non-synchronous random access types are not allowed to select.

[0034] (2) All feature codes except reserved feature codes, that is, common feature codes, can be freely selected by mobile terminals, provided that the wireless access network does not allocate reserved feature codes to these mobile terminals.

[0035] (3) The types of the above feature codes ① and ② in the random access message implicitly indicate the access reason. When the feature code in a random access message is a reserved feature code, it indicates that the access reason is Handover access is thus distinguish...

Abstract

The invention relates to a movable termination switching switch-in network method which is used for marking and differentiating a condition code which is distributed and switched in a condition code set. The method includes the steps that a cell distributes the condition code and sets marks to a movable termination (3) which requests to be switched in the cell in the switching way according to a unique mark principle, the termination switches in through random switch-in message; a movable termination (2) requesting the initial switching-in from an idle state selects the condition code without an mark in the condition code set and switches in a network through a random switching-in message competition. The method uses the mark dynamic state to differentiate the switching switch-in and other random switch-in, a unique mark is used to ensure that the termination requesting switching switch-in at any moment can not initiate the same switching switch-in message in the same switching switch-in message component channel, thereby avoiding the impact among different termination switching switch-in messages and the movable termination identity which cannot be confirmed caused by the impact, reducing the switching time delay significantly and ensuring the communication quality.

Description

technical field [0001] The invention relates to a cellular wireless communication system mainly composed of a mobile terminal, a wireless access network and a core network, in particular to a method for switching and accessing a network by a mobile terminal. Background technique [0002] In a cellular wireless communication system, the system structure is as follows figure 1 , before the mobile terminal 2 communicates with the network, it needs to send a random access message through an uplink common channel. This common channel is called a random access channel, where the network includes a radio access network 1 and a core network 3 . The main purpose of random access of mobile terminals is to obtain occupation of limited wireless channel resources through competition. Sometimes it is also used to obtain synchronization information in the uplink direction. The uplink synchronization information is used by the mobile terminal to decide when to send the uplink signal, so ...
