example 1

[0062] Example 1: As shown in FIG. 8 , the first method is adopted to realize that the adjacent cell Cell belongs to one location area set TA.

[0063] The left side of FIG. 8 is a traditional tree-shaped network structure, wherein: there are four cells Cell1, Cell2, Cell3, and Cell4 under RA1. Cells Cell1-4 belong to TA1, which is a location area managed by rGW1. There are four cells Cell5-8 under RA2, which belong to the location area TA2 managed by rGW2. Similarly, there are five cells Cell9-Cell13 under RA3, which belong to the location area TA3 and are managed by rGW3.

[0064] The right side of Fig. 8 is the network structure configured by method 1. It is configured as follows from the traditional network structure on the left: As can be seen from the figure, Cell4 and Cell5, and Cell8 and Cell9 are adjacent cells. Configure the cell Cell4 under the original RA1 entity and belonging to the location area set TA1 to belong to the location area set TA2 of its adjacent ce...

example 2

[0065] Example 2: As shown in FIG. 9 , the second method is adopted to realize that the adjacent cell Cell belongs to one location area set TA.

[0066]The right side of Figure 9 is the network structure configured from the traditional structure on the left through Method 2. It is configured as follows from the traditional network structure on the left: configure the cell Cell4 belonging to the location area set TA1 under the original RA1 entity to only belong to the location area set TA2 of its adjacent cell Cell5, and configure the cell Cell4 belonging to the location area set under the RA2 entity The cell Cell8 of the set TA2 is configured to belong only to the location area set TA3 of its neighboring cell Cell9. In addition, the rGW2 interface between the RA1 entity and the management location area set TA2 is added; the rGW3 interface between the RA2 entity and the management location area set TA3 is added.

[0067] In addition, as shown in Figure 5, among the multiple ce...

Abstract

The invention comprises: radio access entities and some cells under the control of the radio access entity; the cells under the control of radio access entity can be at different location regions; the neighboring cells located between neighboring radio access entities has same location region set. The invention also provides a switchover method based on said network architecture for realizing the switchover between real-time server and non real-time service which switches user from source cell under the radio access entity to a destination cell or switches the source cell of source radio access entity to the destination cell under the radio access entity in same core network.

Description

technical field [0001] The present invention relates to the technical field of network and communication, in particular to a network architecture and a handover method based on the network architecture. Background technique [0002] A cellular mobile communication system consists of one or more service areas, and different areas have different identities. For the Third Generation Partnership Project (3GPP, 3 rd For the service area of ​​the generation partnership project) system, there are the location area (LA, LocationArea) corresponding to the circuit-switched (CS, Circuit-switched) domain and the routing area (RA, Route Area) of the packet-switched (PS, Packet-Switched) domain. Area). Taking the CS domain of the 3GPP system as an example, its network architecture is shown in Figure 1. A location area usually contains one or more base stations, and one base station manages one or more cells. A tree-like network architecture is formed by location area (LA), base stati...
