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
The present invention relates to 3-G (Generation Three mobile communication system); Relate in particular to HSDPA (High SpeedDownlink Packages Access; The high speed downlink packet access) a kind of resource allocation methods of business and MBMS (MultimediaBroadcast/Multicast Service, multimedia broadcasting and multicast service) service concurrence.
Background technology
MBMS (Multimedia Broadcast/Multicast Service) is called multimedia broadcasting and multicast service, and its bearing mode is divided into two kinds usually: the carrying of point-to-point (PTP) and point-to-multipoint are carried (PTM).Wherein the configuration of PTM service bearer is to give UE (subscriber equipment or title terminal) by RNC (Radio Network Controller, radio network controller) through MCCH (MBMS Control Channel, MBMS control channel) configuration.
TD-SCDMA (Time Division Synchronous Code Division Multiple Access; TD SDMA; Abbreviation TD-SCDMA) multicarrier system is the system that adopts a main carrier and a plurality of auxilliary carrier wave to form; In TD-SCDMA multicarrier system, user carries out that MBMS is professional need to satisfy with non-its resource allocation of MBMS service concurrence that following condition: MBMS is professional to satisfy the separated time slot of alien frequencies with non-MBMS traffic resource assignment needs on different frequencies.So-called alien frequencies is meant that at a distance from time slot business (channel) is on different frequent points and the time slot of being separated by.
In the TD-SCDMA system; If HSDPA is professional concurrent with the professional alien frequencies that carries out of MBMS; Need to consider MBMS business time-slot and MBMS control channel and professional control channel HS-SCCH (downlink high-speed shared control channel) and the HS-SICH (high speed uplink is shared information channel) of HSDPA, HS-PDSCH (high-speed physical downlink shared channel (HS-PDSCH)) channel alien frequencies is at a distance from time slot.Wherein HS-SCCH and HS-SICH are because it is static foundation; The alien frequencies of itself and MBMS can guarantee through configuration at a distance from time slot; But for the HS-PDSCH channel; Because the time slot of its use is by its base station (NodeB) dynamic dispatching, and maybe be different for its resource allocation of each Transmission Time Interval.Therefore, the MBMS of same UE business and HSDPA business can't guarantee that also alien frequencies is at a distance from time slot.
The MBMS time division multiplexing mode is meant that a plurality of MBMS business use identical physical resource through time-multiplexed mode; Its multiplexing cycle is generally the integral multiple of Transmission Time Interval; The professional Transmission Time Interval of MBMS is generally 40ms or 80ms; If so the user of the time-multiplexed mode of certain use MBMS carries out MBMS and HSDPA is concurrent; Then its MBMS business has in the long time (relatively with HSDPA 5ms Transmission Time Interval) not have the data transmission; In MBMS and HSDPA service concurrence, need consider during the NodeB scheduling that the MBMS business does not have the interior service dispatching of cycle of data to need not to satisfy alien frequencies at a distance from time slot, but NodeB can't accomplish but at present.
Summary of the invention
The method of resource allocation when technical problem to be solved by this invention provides a kind of HSDPA and MBMS service concurrence; Under the situation of certain terminal HSDPA business and MBMS service concurrence, but NodeB scheduling HSDPA business is with requirement satisfied and the separated time slot of the professional alien frequencies of MBMS.
For solving the above problems, the invention provides the method for a kind of high-speed downlink packet access HSDPA and multimedia broadcasting and multicast service MBMS resource allocation when concurrent, comprising:
Radio network controller (RNC) is when user equipment (UE) request, change or release MBMS are professional; Perhaps when the HSDPA that carries out this UE is professional; The professional situation about coexisting with the HSDPA business of MBMS will appear if judge this UE; Then said RNC carries the professional resource operating position of MBMS that this UE maybe will carry out in the message of sending to base station NodeB, said NodeB satisfies and the requirement of MBMS service resources alien frequencies at a distance from time slot the HSDPA service resources of distribution when scheduling HSDPA is professional.
Further, said RNC carries the professional resource operating position of MBMS that this UE maybe will carry out in the message of sending to NodeB, is meant that RNC carries the pairing common signal channel sign of said MBMS Traffic Channel in message.
Further, said RNC also carries MBMS control channel and the pairing common signal channel sign of MBMS informing indication channel in the message of sending to NodeB.
Further, if RNC judges the professional time division multiplexing mode of using of said user's MBMS, then said RNC also carries the professional time-multiplexed configuration information of this MBMS in the message of sending to NodeB; After said NodeB receives MBMS time division multiplexing configuration information, when scheduling HSDPA is professional, do not consider the restriction of alien frequencies in free time at a distance from time slot at MBMS.
Further, said time-multiplexed configuration information comprises repetition period, the repeat length of MBMS time division multiplexing and repeats skew.
Further; When UE request or change MBMS business; Perhaps when the HSDPA that carries out this UE is professional; RNC sets up or reconfiguring radio link to NodeB request, after said NodeB receives the message that carries the professional resource operating position of MBMS that said UE maybe will carry out, sets up the corresponding relation of MBMS correlated channels and newly-established or the Radio Link of reshuffling.
Further, said message is: Radio Link is set up request message, radio link reconfiguration is prepared message, Common transport channel deletion request message.
Further; RNC is when UE request, change or release MBMS are professional; Perhaps when the HSDPA that carries out this UE is professional; If judge the situation that said UE will no longer exist MBMS business and HSDPA business to coexist, it is professional that then said RNC indicates this UE not have concurrent MBMS in the message of sending to NodeB, do not consider to satisfy the requirement of MBMS business and the separated time slot allocation of the professional alien frequencies of HSDPA when NodeB carries out the HSDPA service dispatching.
Further, said RNC indicates said UE not have concurrent MBMS business through implicit expression or explicit mode to NodeB.
Further, said RNC increases MBMS information indication information element in message, indicates said UE to discharge or uninterested MBMS service identification.
The present invention is applicable to the TD-SCDMA multi-carrier frequency system, adopts the inventive method, and NodeB is known the professional corresponding resource situation of the MBMS that uses at the terminal in advance, when carrying out the HSDPA traffic resource assignment, makes the resource of distribution can satisfy the requirement of alien frequencies at a distance from time slot.

Embodiment
The present invention is through the information of HSDPA user concurrent MBMS under its administration of RNC (radio network controller) notice NodeB, particularly:
RNC is when certain UE request, change or release MBMS are professional; Perhaps when the HSDPA that carries out this UE is professional; The professional situation with the professional coexistence of HSDPA of MBMS will occur if judge this UE, then RNC sends message to NodeB, (for example in message, carries the professional information of MBMS that UE maybe will carry out; Under the situation of UE request MBMS business, RNC can carry the MBMS business information that will carry out; Under the situation of UE change MBMS business, RNC carries the MBMS business information that maybe will carry out; UE discharges under the professional situation of MBMS, and RNC carries ongoing MBMS business information); NodeB considers the professional situation of MBMS of this terminal concurrence when carrying out the HSDPA service dispatching, the HSDPA service resources of distribution is satisfied and the requirement of MBMS service resources alien frequencies at a distance from time slot.
But the professional information of said MBMS can be the common signal channel sign that is not limited to MBMS related service channel place, can also comprise the common signal channel sign at MBMS control channel place.If the professional time division multiplexing mode of using of this MBMS, then the professional information of MBMS can also comprise the professional time-multiplexed configuration information of this MBMS.If the professional time division multiplexing mode of using of MBMS is not then being sent MBMS in the professional time period, this user HSDPA of NodeB scheduling need not in the time of professional to consider and the condition of the professional alien frequencies of MBMS at a distance from time slot.
RNC is when certain UE request, change or release MBMS are professional; Perhaps when the HSDPA that carries out this UE is professional; To no longer have the professional situation with the professional coexistence of HSDPA of MBMS if judge said UE, promptly exist before this UE HSDPA professional with the MBMS coexistence, but now will otherwise existed; Then RNC sends message to NodeB, and certain UE of notice NodeB does not exist concurrent MBMS professional; When carrying out the HSDPA service dispatching, NodeB do not consider to satisfy MBMS business and of the requirement of the professional alien frequencies of HSDPA at a distance from time slot allocation.
The message that RNC sends to NodeB can be that explicit this UE that indicates does not have concurrent MBMS business, also can come the no concurrent MBMS of indicating of implicit expression professional through not filling in corresponding M BMS business information.
Be that example is described the process that the present invention implements with the TD-SCDMA multi-carrier frequency system below, the message among the embodiment all is consensus standard message.
Embodiment one
Certain UE is carrying out under the professional situation of MBMS; It carries out a HSDPA business again, and (this HSDPA business can be the business that the user initiatively initiates; Business that also can the passive reception of user; Like MMS), its MBMS is professional not to belong to same frequency with the HSDPA business, and flow process is as shown in Figure 1:
Step 101, RNC sends Radio Link to NodeB and sets up request (RADIO LINK SETUPREQUEST) message, carries the pairing common signal channel sign of MTCH (MBMS Traffic Channel) in the message;
Can also carry the pairing common signal channel sign of MCCH (MBMS control channel) and MICH (MBMS informing indication channel) in the message; The sign of these two channels can not carried through this message yet; But, fix on according to appointment in the time slot 0 and carry by RNC and NodeB appointed position.
If the professional time division multiplexing mode of using of this user's MBMS then also need be carried MBMSTDM (time division multiplexing) repetition period, repeat length and repeat skew, related cells is referring to table one.
Step 102, after NodeB received that Radio Link is set up request, NodeB handled the professional relevant information of the MBMS that receives, and responds Radio Link to RNC and set up response (RADIO LINKSETUP RESPONSE);
NodeB can set up the corresponding relation of MBMS correlated channels and this Radio Link after the relevant information of knowing the MBMS channel, when discharging link, NodeB can remove the scheduling restriction of HSDPA scheduling alien frequencies at a distance from time slot voluntarily like this.Because the MBMS Traffic Channel is common signal channel (all users receives simultaneously); Therefore in the professional removal of MBMS (the common signal channel deletion that MBMS is corresponding); NodeB can remove the corresponding relation of HSDPA Traffic Channel alien frequencies at a distance from time slot voluntarily; Need not all to send radio link reconfiguration message and notify its MBMS professional removal to each UE, especially suitable for multi-user's situation, can reduce Iub message greatly and make flow.
Step 103, NodeB is professional according to the situation scheduling HSDPA of this user concurrent MBMS, so that the condition of alien frequencies at a distance from time slot satisfied in its resource allocation.
For example, the MBMS traffic assignments at frequency A, its resource allocation is at time slot 3, MBMS control channel and MICH are configured on the time slot 0, then NodeB needs the scheduling of the HSDPA service resources on the other frequency B of this UE at time slot 5 to satisfy alien frequencies at a distance from time slot.
If the time-multiplexed mode of the professional use of the MBMS of this UE, then the NodeB scheduling HSDPA is constantly professional, does not consider the restriction of alien frequencies at a distance from time slot in free time at MBMS, makes the HSDPA business farthest utilize resource.
Table one RADIO LINK SETUP REQUEST (TDD message)
In the table; The scope of information " MTCH Common Transport Channel ID List (MTCH Common transport channel identification list) " is 1-maxMBMSserv (the professional number of maximum MBMS); This is that to consider that the terminal might be carried out a plurality of MBMS simultaneously professional; Therefore the professional number of the current MBMS that receives simultaneously of this UE is carried simultaneously when RNC request MBMS is professional in the terminal.In other embodiments, also can not consider the situation that a plurality of MBMS are professional.
Embodiment two
The user exists under the professional situation with the HSDPA service concurrence of MBMS, the MBMS business program conversion that the terminal is selected, and flow process is as shown in Figure 2.
Step 201, the terminal is sent MBMS to RNC and is revised request (MBMS MODIFICATIONREQUEST) message, indicates the MBMS business that UE selects in the message;
In message, can inform the professional number of the current MBMS that receives simultaneously of this UE of RNC simultaneously.
Step 202, RNC sends radio link reconfiguration to NodeB and prepares (RADIO LINKRECONFIGURATION PREPARE) message;
Carry the pairing common signal channel sign of MTCH in the message; Also the pairing common signal channel sign of portability MCCH and MICH if this user's MBMS business is used time division multiplexing mode simultaneously, then also need be carried the MBMS TDM repetition period; Repeat length and repeat the skew, referring to table two.
Step 203; After NodeB receives that radio link reconfiguration is prepared message; Preserve relevant information; Set up the corresponding relation (in other embodiments, also can not setting up) of MBMS correlated channels and this Radio Link simultaneously, NodeB responds radio link reconfiguration ready (RADIO LINKRECONFIGURATION READY) message to RNC;
Step 204, NodeB carries out the scheduling HSDPA business according to the situation of the concurrent MBMS of this UE, so that the condition of alien frequencies at a distance from time slot satisfied in its resource allocation.
If the time-multiplexed mode of the professional use of the MBMS of this UE; Then the NodeB scheduling HSDPA is constantly professional; Do not consider the restriction of alien frequencies in free time at MBMS at a distance from time slot; Promptly at MBMS in professional free time, for the resource of HSDPA traffic assignments need not to make user HSDPA business farthest utilize resource at a distance from time slot again.
Table two RADIO LINK RECONFIGURATION PREPARE (TDD Message)
Embodiment three
The MBMS that network side is initiated is professional to be discharged, as shown in Figure 3.
Embodiment four
Under the situation that has MBMS business and HSDPA service concurrence, the MBMS business program that the terminal selection is not watched, flow process is as shown in Figure 4.
Step 401, the terminal is sent MBMS to RNC and is revised request (MBMS MODIFICATIONREQUEST) message, and indicating UE in the message does not have MBMS service interested (the MBMS business program sign of not watching);
Step 402, RNC sends RADIO LINK RECONFIGURATIONPREPARE message to NodeB, fills in MBMS Information Indicate in the message and indicates UE and do not have MBMS service identification (seeing table two) interested;
Present embodiment is an example with explicit notification NodeB, in other embodiments, and also can be through implicit method notice NodeB, as not filling in corresponding MBMS cell.
Step 403; After NodeB receives RADIO LINK RECONFIGURATION PREPARE message; Respond RADIO LINK RECONFIGURATION READY to RNC, these user's scheduling HSDPA user resources of NodeB cancellation are distributed the restrictive condition that satisfies the separated time slot of alien frequencies.
The present invention also can have other numerous embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Be familiar with those of ordinary skill in the art and can make various corresponding changes and distortion, but these corresponding changes and distortion all should belong to protection range of the presently claimed invention according to the present invention.
