Problems solved by technology

Compared with the CDMA 1x circuit domain core network, IMS does not introduce other valuable new services, so it is not urgent to deploy IMS, and it also increases the cost of network construction, which is not conducive to investment protection

Embodiment 1

[0057] like Figure 5 As shown, a voice service processing method under the evolution from a CDMA network to an LTE network, the execution subject of the method may be a single-carrier wireless transmission circuit domain interoperability functional entity (1x circuit switch Interworking Solution, 1xCS IWS), including:

[0058] S51. Receive a first trigger message (for example, an origination message or a paging response message) from a user equipment (User Equipment, UE) through the LTE network, and send a second trigger message (for example, a connection management ( Connect Management, CM) service request message or paging response message).

[0059] Among them, the MSC belongs to the service equipment of the CDMA 1x circuit domain.

[0060] S52. Receive an assignment request message for allocating dedicated resources for the UE sent by the MSC in response to the second trigger message.

[0061] S53. Based on the assignment request message, allocate first voice bearer inf...

Embodiment 2

[0085] like Image 6 As shown, the embodiment of the present invention provides a voice service processing method under the evolution from a CDMA network to an LTE network. The executor of the method may be a user equipment UE under the evolution from a CDMA network to an LTE network. The method may include:

[0086] S61. When the first trigger condition is met, send an extended service request message carrying a CSoEPS indication to the MME;

[0087] Wherein, the first triggering condition may be that the UE decides to initiate the caller voice service (if the UE is in the LTE idle state, the service request process is transferred to the LTE active state); or the first triggering condition may also be that the UE passes the LTE The network receives the paging message from the 1xCS IWS, that is, the current UE is the called party.

[0088] It should be noted that the voice solution in the embodiment of the present invention may be referred to as CSoEPS (CS over EPS) for short...

Embodiment 3

[0113] like Figure 7 As shown, the embodiment of the present invention provides a voice service processing method under the evolution from a CDMA network to an LTE network when the UE initiates a calling voice service, and the specific steps include:

[0114] S701, UE 1501 is attached to the LTE network, and registers with the CDMA 1x circuit domain through the LTE network, so that the 1x circuit domain core network has the context information of the UE 1501 (such as UE user identity, mobility management status, user security parameters, etc.), Knowing the location information of the UE 1501, the voice calling and calling service can be initiated through the 1x circuit domain core network.

[0115] S702. The UE 1501 decides to initiate a calling voice service. If the UE 1501 is in the LTE idle state, the process of initiating a service request transitions to the LTE active state.

[0116] S703. The UE 1501 sends an extended service request message to the MME 1505, where the ...

Abstract

The embodiment of the invention discloses a voice service processing method, a voice service processing system and a voice service processing device in evolution from a code division multiple access (CDMA) network to a long term evolution (LTE) network. The method comprises the following steps of: receiving a first trigger message from user equipment (UE) through the LTE network and sending a second trigger message to a mobile switching center (MSC) of a CDMA single carrier radio transmission network 1x; receiving an assignment request message for assigning a resource special for the UE, which is sent by the MSC for responding the second trigger message; assigning first bearing voice information for the UE on the basis of the assignment request message and sending a bearing establishment request message which at least carries the first bearing voice information to the UE through the LTE network; receiving a bearing establishment response message which at least carries second bearing voice information from the UE through the LTE network; and sending voice stream information which comprises the first bearing voice information and the second bearing voice information to a policy and charging rules function (PCRF) and requesting the PCRF to establish a bearing special for voice for the UE in the LTE network. The LTE network can provide the data service, so the voice service and the data service can be provided in the LTE network without the assignment of an internet protocol (IP) multimedia subsystem (IMS) by adopting the scheme.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a voice service processing method, system and device under the evolution from CDMA to LTE. Background technique [0002] The Long Term Evolution (LTE) network improves and enhances the air access technology of the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP). The network architecture of LTE in the case of non-roaming is as follows: figure 1 As shown, the evolved base station is responsible for data modulation and demodulation, channel codec, radio resource control, wireless mobility management, etc.; the serving gateway and the packet data network gateway are evolved gateways, responsible for forwarding data packets; the mobility management entity The Mobility Management Entity (MME) is a signaling control entity of the LTE system, responsible for functions such as authentication and mobility management. The evolved network does not provi...
