Problems solved by technology

Among them, HS-SCCH and HS-SICH are established statically, and the different frequency interval time slots between them and MBMS can be guaranteed through configuration, but for HS-PDSCH channels, since the time slots used by them are dynamically determined by their base station (NodeB) scheduled, and its resource allocation may be different for each transmission time interval
Therefore, the MBMS service and HSDPA service of the same UE cannot guarantee different frequency interval time slots
[0005] The MBMS time-division multiplexing method means that multiple MBMS services use the same physical resource through time-division multiplexing. The multiplexing cycle is generally an integer multiple of the transmission time interval. The MBMS service transmission time interval is usually 40ms or 80ms. Therefore, a certain If a user using MBMS time division multiplexing performs MBMS and HSDPA concurrently, the MBMS service will have no data transmission for a relatively long period of time (compared to the 5ms transmission time interval of HSDPA). When MBMS and HSDPA service are concurrent , when NodeB schedules, it needs to consider that MBMS service does not need to meet different frequency and time slots during the period when there is no data in the MBMS service, but currently NodeB cannot do it

Embodiment 1

[0030] When a certain UE is already performing MBMS services, it then performs another HSDPA service (the HSDPA service can be initiated by the user or passively received by the user, such as MMS service). The MBMS service is different from the HSDPA service. belong to the same frequency point, the process is as follows figure 1 Shown:

[0031] Step 101, the RNC sends a radio link setup request (RADIO LINK SETUPREQUEST) message to the NodeB, and the message carries the corresponding public channel identifier of the MTCH (MBMS Traffic Channel);

[0032] The common channel identifiers corresponding to MCCH (MBMS Control Channel) and MICH (MBMS Notification Indication Channel) can also be carried in the message, and the identifiers of these two channels can also not be carried by this message, but the positions agreed by RNC and NodeB, such as agreed Carried in slot 0.

[0033]If the user's MBMS service uses time division multiplexing, it also needs to carry the MBMS STDM (time...

Embodiment 2

[0044] When the user already has concurrent MBMS services and HSDPA services, the MBMS service program selected by the terminal is changed, and the process is as follows: figure 2 shown.

[0045] Step 201, the terminal sends an MBMS modification request (MBMS MODIFICATIONREQUEST) message to the RNC, indicating the MBMS service selected by the UE in the message;

[0046] In the message, the RNC may be notified of the number of MBMS services currently received by the UE at the same time.

[0047] Step 202, RNC sends radio link reconfiguration preparation (RADIO LINKRECONFIGURATION PREPARE) message to NodeB;

[0048] The message carries the common channel identifier corresponding to MTCH, and can also carry the common channel identifier corresponding to MCCH and MICH. At the same time, if the user's MBMS service uses time division multiplexing, it also needs to carry the MBMS TDM repetition period, repetition length and repetition period. Offset, see Table 2.

[0049] Step 20...

Embodiment 3

[0056] MBMS service release initiated by the network side, such as image 3 shown.

[0057] Step 301, the RNC sends a common transport channel deletion request (COMMONTRANSPORT CHANNEL DELETION REQUEST) message to the NodeB, requesting to delete the corresponding MBMS service channel, and the common channel identifier corresponding to the MTCH is carried in the message;

[0058] Step 302, after receiving the COMMON TRANSPORT CHANNEL DELETIONREQUEST message, the NodeB deletes the relevant common channel, and responds to the wireless network control with a common transport channel deletion response (COMMON TRANSPORT CHANNEL DELETION RESPONSE) message;

[0059] Step 303, NodeB detects HSDPA users concurrently with the MBMS service according to the MBMS corresponding public channel ID (NodeB saves the corresponding relationship between each wireless link and the public channel ID when establishing a wireless link of HSDPA and MBMS concurrent service), NodeB Cancel the resource al...

Abstract

The invention discloses a resource allocation method during the concurrence of HSDPA (high speed downlink packet access) service and MBMS (multimedia broadcast multicast service) service. During the concurrence of the HSDPA service and the MBMS service at a terminal, Node B can dispatch the HSDPA service to meet the requirement of the different-frequency interval time slot of the MBMS service. The method comprises the following steps that when UE (user equipment) requests, changes or releases the MBMS service or the HSDPA service of the UE is in progress, a RNC (radio network controller) judges if the UE is in a condition of the concurrence of the MBMS service and the HSDPA service, the RNC enables a message sent to a base station Node B to carry the resource usage condition of the MSMS service which is under way or is to be carried out by the UE, and the Node B enables an allocated HSDPA service resource to meet the requirement of the different-frequency interval time slot of the MBMS service when dispatching the HSDPA service.

Description

technical field [0001] The present invention relates to a third-generation mobile communication system, in particular to a resource allocation method for concurrent HSDPA (High Speed ​​Downlink Packages Access) services and MBMS (Multimedia Broadcast / Multicast Service, multimedia broadcast and multicast services). Background technique [0002] MBMS (Multimedia Broadcast / Multicast Service) is called multimedia broadcast and multicast service, and its bearer mode is generally divided into two types: point-to-point (PTP) bearer and point-to-multipoint bearer (PTM). The configuration of the PTM service bearer is configured by the RNC (Radio Network Controller, radio network controller) to the UE (user equipment or terminal) through the MCCH (MBMS Control Channel, MBMS control channel). [0003] TD-SCDMA (Time Division Synchronous Code Division Multiple Access, TD-SCDMA for short) multi-carrier system is a system composed of a main carrier and multiple auxiliary carriers. In the ...
