Problems solved by technology

[0006] In the process of realizing the present invention, the inventor found that: the second method needs to upgrade the BSC to realize the delivery of SI3, and the extensive deployment of the BSC in the Public Land Mobile Network (Public Land Mobile Network, PLMN) will lead to BSC upgrade work is very heavy
In addition, when MSC in pool (MSC resource pool) technology is used, a BSC can be connected to any MSC in the MSC resource pool, and the MSCs in the MSC resource pool will include MSCs that can correctly process AMR-WB capability information and different MSCs. For MSCs that can correctly process AMR-WB capability information, since SI3 is system information and is not specific to a specific call, the setting of whether to allow terminals to report AMR-WB capability information in SI3 cannot be specific to each individual call in the MSC resource pool. MSC treats them differently, which will either result in ineffective use of the AMR-WB capability of the terminal, or cause call failure
In addition, when the packet service performed by the terminal is in Packet Transfer Mode (packet transfer mode), since the terminal will not monitor SI3, it can only send SI3 through the Packet SI Status (packet SI status) message. If the BSC does not support Packet SI Status message, the BSC cannot issue to the terminal whether to allow the terminal to report the AMR-WB capability information, and the call will fail due to the AMR-WB capability information reported by the terminal

Embodiment 1

[0055] Embodiment 1. A method for reporting capability information. The flow of the method is attached figure 1 shown.

[0056] figure 1 In S100, the mobile switching center that establishes the service sends indication information to the terminal whether to support the broadband adaptive multi-rate capability. The indication information is used to notify the terminal whether to report broadband adaptive multi-rate capability information to the mobile switching center. The indication information can indicate whether the mobile switching center that establishes the service supports the broadband adaptive multi-rate capability, and the indication information can also indicate whether the mobile switching center allows the terminal to report the indication information of the broadband adaptive multi-rate capability. Therefore, the above mobile switching The indication information of whether the center supports the broadband adaptive multi-rate capability may also be referred t...

Embodiment 2

[0077] Embodiment 2, a method for reporting capability information. The flow of the method is attached figure 2 shown.

[0078] figure 2 Among them, S200. During the process of establishing a circuit domain service, the base station controller sends indication information indicating whether the mobile switching center supports broadband adaptive multi-rate capability to the terminal through layer 3 signaling. The indication information here is used to notify the terminal whether to report the broadband adaptive multi-rate capability information to the mobile switching center, and the indication information can indicate whether the mobile switching center supports the broadband adaptive multi-rate capability.

[0079] The base station controller can know whether the mobile switching center connected to it supports the broadband adaptive multi-rate capability by means of preset information or the like.

[0080] The base station controller can use the idle bits in the existi...

Embodiment 3

[0086] Embodiment 3, a method for reporting capability information. The flow of the method is attached image 3 shown.

[0087] image 3 In S300, the terminal carries the broadband adaptive multi-rate capability information in the newly added information element of the message, and sends the message to the mobile switching center. The newly added cells here can be identified by the mobile switching center that supports the broadband adaptive multi-rate capability, and cannot be identified by the mobile switching center that does not support the broadband adaptive multi-rate capability. The terminal here is a terminal supporting the broadband adaptive multi-rate capability.

[0088] In S300, the terminal may receive the indication information sent by the base station controller or the mobile switching center whether the mobile switching center supports the broadband adaptive multi-rate capability, and judge according to the indication information that it is allowed to report...

Abstract

The invention discloses a method and device for reporting capability information. The method for reporting the capability information comprises the step of transmitting the indication information for indicating whether a mobile switching center supports the bandwidth self-adaption multi-rate capability or not to a terminal by the mobile switching center for establishing services, wherein the indication information is used for noticing whether the terminal reports the bandwidth self-adaption multi-rate capability information or not to the mobile switching center. The technical scheme can avoidthe phenomenon of call failure caused by that the terminal reports the bandwidth self-adaption multi-rate capability information, thereby improving the success rate of the call.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to the capability information reporting technology. Background technique [0002] During the call establishment process, the terminal supporting Adaptive Muilti Rate Wideband (Adaptive Multi-Rate Broadband, AMR-WB) should report the AMR-WB supporting capability information to the Mobile Switching Center (Mobile Switching Center, MSC). [0003] A kind of AMR-WB capability information reporting method is: in the Traffic Channel (traffic channel, TCH) assignment phase that terminal initiates calling, terminal will indicate whether to support the AMR-WB capability information of AMR-WB through the BearerCapability IE( The Speech Version (voice version) field of the bearer capability information element) is reported to the MSC; in the TCH assignment stage when the terminal is called, the terminal will pass the Speech of the Bearer Capability IE of the Call Confirm (call con...
