Embodiment 1

[0035] Embodiment 1: The called party is a single-number mobile user

[0036] The typical application of data services under the 3GPP R4 network is shown in Figure 1. Incoming calls enter through GMSC and go to the called VMSC (Visited Mobile Switching Center mobile terminal office) for MT (mobile terminating) calls. The incoming call can use ISUP (ISDN). User Part ISDN user part) signaling, GMSC to VMSC adopts IP bearer, and BICC (Bearer Independent Call Control Protocol bearer independent call control protocol) signaling is used between offices.

[0037] As shown in Figure 1, the process of this embodiment mainly includes the following steps:

[0038] 1. After receiving the IAM message, the GMSC sends an SRI message to the HLR;

[0039] 2. The HLR judges whether the call is a voice service call or a data service call based on the subscription information of the called party, and then sends an SRI_ACK message to the GMSC. The optional cell basicservice code is added to the messag...

Embodiment 2

[0047] Embodiment 2: The called is a dual-number mobile user

[0048] For dual-number mobile users, according to the different voice and data subscription services, when the gateway office GMSC inquires the routing data from the HLR, the HLR determines whether the call is a data service or a voice service according to the correspondence between the called subscription information and the called number, and then Return the SRI-ACK message to the GMSC, and add optional information elements in the SRI-ACK message, such as basic service code, which carries information about the service type. According to the type of this call, the GMSC can issue different information to the corresponding gateway. Codec establishes the call bearer: for voice calls, the compression codec algorithm is used, and for data service calls, the call bearer is established by G.711 transparent transmission.

[0049] The flow of this embodiment is shown in Figure 2, and includes the following steps:

[0050] 1. A...

Abstract

This invention discloses one test business type method and device, which comprises the following steps: a, belonging position register HLR receives send router information SRI message from mobile exchange center GMSC to judge this item call business type; b, the said HLR sends router SRI_ACK message to GMSC portable with this call business type information.

Description

Technical field [0001] The present invention relates to the field of 3G technology, and in particular to a technology for the detection and processing of data services by GMSC (Gateway Mobile Switching Center) under a network architecture where bearer and control are separated. Background technique [0002] Under the network architecture before 3GPP R99 (the third-generation mobile communication partnership agreement R99 standard), because the bearer and control are integrated, and they are all connected based on TDM (Time Division Multiplex), data services The call only needs to complete the TDM connection to the GMSC. Since there is no voice compression codec, the data bearer is transparently transmitted on the TDM connection, and there is no additional requirement. [0003] In networks after 3GPP R4, the bearer and control are separated. The bearer network is basically connected based on a non-TDM method, and the core network service bearer needs to be completed by compressing...
