Problems solved by technology

[0018] In the solution of the prior art, the signaling interaction process between RNCs is complicated, including not only connection-oriented messages but also non-connection-oriented messages, which is inconsistent with the MBMS service establishment process of the 3GPP RANAP protocol
In addition, in the process of establishing the MBMS service synchronous bearer, the SRNC and DRNC are required to perform a certain preparation process before interacting after receiving the MBMS SESSION START message. In the existing scheme, the default MBMS SESSION START message arrives at each RNC at the same time or almost simultaneously. Considering that the order in which the MBMS SESSION START message arrives at each RNC may be different in actual operation, if the DRNC has made corresponding preparations and initiated the MBMS synchronization bearer establishment process, but the SRNC has not made corresponding preparations, it will return the MBMS synchronization bearer rejection to the DRNC Establishment (MBMS SYNC BEAR SETUP REJECT) may cause the problem that the MBMS synchronous bearer cannot be established

Embodiment Construction

[0049] The solution of the present invention improves the processing process on the DRNC side. When the DRNC receives the MBMSSESSION START message, it directly distributes the transport layer address and the transport layer binding identifier locally instead of between the SRNC and the DRNC as in the prior art. During the interactive process of MBMS synchronous bearer establishment, the transport layer address and transport layer binding identifier are reassigned, so that the transport layer address and transport layer binding identifier on the DRNC side can be directly carried in the message during the interactive process of MBMS synchronous bearer establishment Sent to SRNC.

[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0051] The processing flow of the DRNC side of the embodiment of the present invention is as ...

Abstract

The invention discloses a method for establishing multimedia broadcast multicast (MBMS) service synchronous bearer, which comprises the following steps: after a DRNC receives MBMS service establishment messages from a core network, establishing an MBMS service processing entity inside the DRNC, and allocating IUR interface local resources; sending MBMS synchronous bearer establishment request messages with an MBMS service identifier and the IUR interface local resources of the DRNC to an SRNC from the DRNC; starting up a timer through the DRNC and judging whether the timer receives MBMS synchronous bearer establishment response messages from the SRNC or not before timeout; if so, binding the IUR interface local resources of the DRN and the IUR interface local resources of the SRNC in the MBMS synchronous bearer establishment response messages; otherwise sending the MBMS service establishment request messages again, and turning to the step for judging whether the MBMS service response messages are received or not.

Description

technical field [0001] The invention relates to the field of multimedia broadcast multicast service (MBMS), in particular to a method and a system for establishing MBMS service synchronous bearer. Background technique [0002] To realize the synchronization of MBMS services between multiple RNCs in the MBMS synchronization area, the following conditions need to be met: for the same MBMS service, each RNC in the MBMS synchronization area has the same radio resources, and the RNCs transmit at the same time The same MBMS data. The block diagram of the existing MBMS synchronous bearer system is as follows: figure 1 As shown, only one DRNC is shown as a representative, and there may be more than one DRNC in actual situations. [0003] The operator configures the role of each RNC in the MBMS synchronization area through the operation management system (O&M), that is, configures a master RNC (SRNC), and other RNCs are configured as slave RNCs (DRNC), and each DRNC has an IUR inte...
