Example Embodiment

[0037] Example one

[0038] In this embodiment, the MME sends a connection establishment request to the pre-registered base station, and the pre-registered base station exchanges information with the target base station, such as figure 2 Shown is a schematic flowchart of Embodiment 1 of the present invention, and the process includes:

[0039] Steps 200-204 are basically the same as the prior art, except that the source base station makes a handover decision after receiving the TE measurement report on the target system, and decides to switch to a new target base station, and the target base station is not the same as the pre-registered base station A base station.

[0040] Step 205: The source base station sends a connection establishment request to the MME. The request carries the pre-registered base station identifier (static sector ID) and the newly selected target base station identifier (selected sector ID);

[0041] Step 206: The MME sends a connection establishment reques...

Example Embodiment

[0060] Example two

[0061] In this embodiment, the MME sends a connection establishment request to the target base station, and the target base station exchanges information with the pre-registered base station, such as image 3 Shown is a schematic flowchart of Embodiment 2 of the present invention, and the process includes:

[0062] Step 300-Step 304 are the same as Step 100-Step 104 in the prior art, except that the source base station makes a handover decision after receiving the TE measurement report on the target network, and decides to switch to another target base station. The registered base station is not the same base station.

[0063] Step 305: The source base station sends a connection establishment request to the MME, and the request carries the pre-registered base station identifier (static sector ID) and the newly selected target base station identifier (selected sector ID);

[0064] Step 306: The MME sends a connection establishment request to the target base sta...

Example Embodiment

[0077] Example three

[0078] Such as Figure 4 Shown is a schematic flow chart of an alternative embodiment of the present invention. In this embodiment, the pre-registered base station no longer meets the TE handover requirements. The pre-registered base station selects a new target base station according to the TE measurement report. The process includes:

[0079] Step 400 to step 403 are the same as step 100 to step 103 in the prior art;

[0080] Step 404: TE sends a connection establishment request to the source base station, and the request carries the measurement report of the target system;

[0081] Step 405: The source base station sends a connection establishment request to the MME, and the request carries the measurement report of the target system;

[0082] Step 406: The MME sends a connection establishment request to the pre-registered base station, and the request carries the measurement report of the target system;

[0083] Step 407a to step 416 are the same as step ...

Abstract

The invention discloses a method for treating switching among heterogeneous systems, which comprises that an MME receiving source base station sends a connection establishment request, and the request carries a pre-registration base station mark; the pre-registration base station receives the connection establishment request from the MME; and a transmission channel is established between the pre-registration base station and a target base station. The invention also discloses a base station and a system, which are used for treating the switching among the heterogeneous systems. By using the method, the device and the system provided by the invention, if the pre-registration base station is not the same as the target when in formal switching, the failure of switching among the heterogeneous systems can be avoided when a pre-registration switching is carried out.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method for handling handover between heterogeneous systems. Background technique [0002] At present, the development of communication technology is changing with each passing day, and various new access technologies emerge in an endless stream. Since the networks corresponding to various access technologies usually have their own suitable coverage and application scenarios, in order to realize ubiquitous communication services, multi-mode terminals supporting multiple access technologies emerge as the times require. A network using different access technologies is called a heterogeneous system. A multi-mode terminal that supports multiple access technologies, that is, multiple heterogeneous systems, must solve a problem: how the multi-mode terminal seamlessly switches and roams among the heterogeneous systems it supports. [0003] Regarding the handover between heterogeneous ...
