Embodiment 1

[0032] Embodiment 1: The called party is a single-number mobile user

[0033] Typical applications of data services under 3GPP R4 networking are as follows: figure 1 As shown, the incoming call enters through the GMSC and goes to the called VMSC (Visited Mobile Switching Center) for MT (mobile terminating) calls. The incoming call can use ISUP (ISDN User Part) signaling, and GMSC to VMSC uses For IP bearer, BICC (Bearer Independent Call Control Protocol) signaling is used between offices.

[0034] Such as figure 1 As shown. The process of this embodiment mainly includes the following steps:

[0035] 1. After receiving the IAM message, the GMSC sends an SRI message to the HLR;

[0036] 2. The HLR judges whether the call is a voice service call or a data service call according to the subscription information of the called party, and then sends an SRI_ACK message to the GMSC, in which an optional cell basicservice code is added to carry the service type of the call informatio...

Embodiment 2

[0044] Embodiment 2: The called party is a dual-number mobile user

[0045] For dual-number mobile subscribers, according to different voice and data subscription services, when the gateway office GMSC queries the routing data to the HLR, the HLR judges whether the call is a data service or a voice service according to the corresponding relationship 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, carrying service type information. The GMSC can send different information to the corresponding gateway according to the call type. Codec establishes call bearer: For voice calls, the compression codec algorithm is used, and for data service calls, G.711 transparent transmission is used to establish call bearers.

[0046] The process of this embodiment is as follows figure 2 shown, including the following steps:

[0047] 1. Af...

Abstract

A method and a device for testing the service type. The method comprises the following steps: receiving the send routing information message to judge the service type of this call; and returning the send routing response information with the service type information of this call.

Description

technical field [0001] The present invention relates to the technical field of 3G, in particular, relates to a technology for detecting and processing data services by a GMSC (Gateway Mobile Switching Center) under a network architecture in which bearer and control are separated. Background technique [0002] Under the network architecture before 3GPP R99 (third-generation mobile communication partner agreement R99 standard), since bearer and control are integrated, and are connected based on TDM (Time Division Multiplex), data services The call needs only 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 the network after 3GPP R4, bearer and control are separated, the bearer network is basically connected based on non-TDM mode, and core network service bearer needs to be completed by compression codec. Since the compre...
