Problems solved by technology

[0016] In short, the user equipment monitors the paging indication periodically, and the size of the period is determined by the core network and notified to the user equipment through related radio resource control (RRC) messages; if the period is longer, the user equipment (UE) The smaller the chance of waking up from sleep, the smaller the power consumption it consumes, thereby prolonging the battery standby time of the user equipment. The disadvantage is that it reduces the response speed of the terminal to paging from the core network
The modification of the paging message can refer to the WB-FDD method, but how to carry the MBMS paging indication on the existing paging indication channel frame must provide a new method

Embodiment Construction

[0052] The present invention proposes a method for paging Multimedia Broadcast and Multicast Service (MBMS for short) in the WB-TDD system. Its core is how to use the reserved bits in several persistent paging indication channel frame structures in the existing paging indication block to transmit the paging indication of the upcoming MBMS service.

[0053] How to utilize the reserved bits in several persistent paging indicator channel frame structures in the existing paging indicator block to transmit the method of the paging indicator (MPI for short) of the MBMS service that will take place is the key point of the present invention, below we will be described in detail.

[0054] In order to distinguish it from the variables used in the user-based point-to-multipoint paging mode in the existing 3GPP specifications, the present invention uses variables beginning with m_ to identify the variables used in MBMS paging.

[0055] from Figure 5 , it can be known that in the curren...

Abstract

The invention is a calling MBMS method used in wide-band time division diplex mobile communication system, after receiving GGSN-sent data, SGSN sends MBMS notice to RNC; after receiving the MBMS notice, RNC constructs wireless network controller and two continuous frames of base-station interface frame protocol according to the content of the notice, where the frame protocol contains MBMS indication bit, calling indication and calling message; RNC transmits a frame of the frame protocol to base station; after receiving the frame, the base station firstly checks the indication bit: if the indication bit is 0, it shows the frame is tradition calling and if the indication bit is 1, it shows the frame contains MBMS service message; the base station checks the calling indication bit: if the indication bit is 1 and MI is 1, it uses the unused 4 retained bits in each PICH to bear MBMS service calling indication.

Description

technical field [0001] The present invention relates to a wideband code division multiple access (abbreviated WCDMA) mobile communication system, specifically, in a wideband time division duplex mode in a wideband code division multiple access (abbreviated WCDMA) mobile communication system, paging multimedia broadcast and multicast service (abbreviated MBMS) ) method, which mainly provides how to use the reserved bits in the frame structure of several persistent paging indication channels in the existing paging block to transmit the paging indication of MBMS service. Background technique [0002] Currently, the 3rd Generation Partnership Project (hereinafter referred to as 3GPP) is standardizing Multimedia Broadcast and Multicast Service (hereinafter referred to as MBMS). It is a point-to-multipoint unidirectional service, and the biggest feature of this kind of service is that it can effectively utilize wireless resources and network resources. [0003] Figure 1 depicts ...
