Embodiment 1

[0053] Embodiment 1: Traditional circuit domain TDM networking, the flow chart of handover between pools is as attached Image 6 Shown:

[0054] At this time, switching circuits are configured between MSC4 and HF1, between HF1 and HF2, and between HF2 and MSC5, and HF has the function of switching circuit management.

[0055] 1. MSC4 receives a Handoff Required (handover request) message from BSC6, which carries target MSC information and cell information;

[0056] 2. MSC4 judges that the target MSC is not in its own pool, then sends an interoffice handover message FACDIR2 (device indication) to the handoff function entity Handoff Function 1 (HF1) of this pool, and FACDIR2 carries the interoffice handover circuit identifier CIC1 allocated by MSC4;

[0057] 3. Handoff Function 1 receives the FACDIR2 message, analyzes the target MSCID (mobile switching center identifier), and judges that it belongs to the pool where Handoff Function 2 belongs to, then forwards the message to Ha...

Embodiment 2

[0081] Embodiment 2: Under the mobile softswitch architecture, the process of switching from the MSCe in the pool to the MSCe outside the pool that does not support the A-Flex feature is shown in the attached Figure 7 As shown, the process of MSCe managing the media gateway belongs to the prior art, which is not reflected in the figure and corresponding explanatory text:

[0082] In order to complete the handover between MSCe2 (mobile softswitch center) in the pool and MSCe5 outside the pool that does not support the A-Flex feature, the handover data is configured between HF1, MSCe2 and MSCe5, when it is applied to the softswitch after the inter-office signaling interface is IP-based When connecting to the network, the HF must also have the ability to process SIP signaling related to inter-office handover.

[0083] 1. MSCe2 receives the Handoff Required message from BSC3, which carries the target location area cell information;

[0084] 2. MSCe2 judges that the target locati...

Embodiment 3

[0103] Embodiment 3: In the case of mixed networking of traditional circuit switching and mobile softswitch equipment, the flow of switching from MSCe in the pool to MSC outside the pool that does not support the A-Flex feature is shown in the attached Figure 8 As shown, the process of MSCe managing the media gateway belongs to the prior art, which is not reflected in the figure and corresponding explanatory text:

[0104] In order to complete the handover between the MSCe2 (Mobile Soft Switch Center) in the pool and the traditional circuit switching MSC5 outside the pool that does not support the A-Flex feature, the handover data is configured between HF1, MSCe2 and MSC5, and HF1 further needs to have a media gateway management and handover circuit management functions.

[0105] 1. MSCe2 receives the Handoff Required message from BSC3, which carries the target location area cell information;

[0106] 2. MSCe2 judges that the target location area cell is not in its own pool,...

Abstract

The invention relates to a method for realizing inter-junction switch in the A-Flex circuit field, and relative system. Wherein, said method comprises: a, the switch function solid HF receives the inter-junction switch request message to mobile exchange center MSC, based on the information of said request message, to build conversation, and select the target cord network node to send said inter-junction switch message; b, the target core network receives the inter-junction switch request message, to complete the switch. The invention can effectively reduce the number and complexity of switch path and data set when switching in and out pools, with easy capacity expansion and data maintenance; and pool is added with MSC, which only needs to add the switch path and relative data from said MSC to the HF, with changing the connection relationship and the data set; and it is transparent to other pools, to effectively reduce the operation complexity.

Description

technical field [0001] The present invention relates to the technical field of A-Flex, in particular, to the technology of inter-office handover under the A-Flex architecture. Background technique [0002] In a network that does not support flexible interfaces between the access network and the core network, one mobile switching center (MSC) can connect to multiple base station controllers (BSC), but one base station controller can only connect to one mobile switching center. The connection relationship between MSC and BSC in CDMA2000 circuit domain network under this architecture is as attached figure 1 shown. [0003] This 1:N relationship between the mobile switching center and the base station controller restricts the flexibility of the networking. First, the user capacity of the MSC is getting larger and larger. When an MSC is shut down for maintenance, is seriously overloaded or fails , all the BSCs connected to the MSC will lose their function, and the users within ...
