Embodiment
In order to solve the problem that does not have the MBMS request mechanism, embodiments of the invention provide a kind of MBMS requesting method.The MBMS requesting method that embodiments of the invention provide, UE is sent the MBMS solicited message as triggering one of condition that inserts at random, the UE that need carry out the MBMS request triggers random access procedure, by the process that inserts at random the relevant information of the MBMS of UE request is sent to network side.Can save a lot of standardisation process like this, by for the utilization of prior art with improve the transmission of the relevant information that realizes MBMS request process and MBMS request.Be applicable to the transmission of UE, can satisfy the demand of UE to the transmission of the one or more MBMS of network side request to the one or more MBMS of network side request.
Concrete, UE (needing to initiate the UE of MBMS request) triggers uplink random and inserts, UE sends random access sequence to network side, network side distributes ascending resource for the UE that sends described sequence, UE sends the MBMS solicited message to network side on the ascending resource that is distributed, the MBMS solicited message that the network side response receives sends response message to UE.
Below in conjunction with accompanying drawing, embodiments of the invention one are described.
The embodiment of the invention uses process that this method finishes MBMS request as shown in Figure 1, comprising:
In this step, UE triggers random access procedure when needs request MBMS, send random access sequence to network side.
After step 102, network side receive described random access sequence, for described UE distributes ascending resource;
In this step, network side is according to the random access sequence that receives, for the UE that sends described sequence distributes ascending resource.
In the embodiment of the invention, it is one of following that described network side comprises: cell cooperative entity (MCE, Multi-cell/multicast Coordination Entity), base station (eNB), relay station (relay), broadcast multicast service center (BMSC, Broadcast Multicast Service Centre), MBMS gateway (MBMS GW, MBMS GateWay).
The MBMS solicited message comprises the MBMS sign, can also comprise the one or more of following sign:
MBMS request mark and UE sign.
Wherein, the MBMS sign is the service identification of the MBMS of this UE request, can be one or more.The MBMS request mark is to show that the information that this UE sends is the information that a request network side sends MBMS, rather than the information of other purposes.The UE sign is the identification information that is used for showing this UE identity, for example can be ue-Identity, perhaps S-TMSI, perhaps 40 bit value at random.
The transmission of concrete MBMS solicited message can be adopted RRC (Radio Resource Control, Radio Resource control) form of message (message) sends, perhaps adopt MAC (Medium Access Control, the multimedia access control) CE (Control Element, control unit) form sends, perhaps adopt MAC SDU (Service Data Unit, business datum unit) form to send.Below these three kinds of send modes are specifically described.
When adopting RRC message to send the MBMS solicited message, the connection that network side does not need to finish NAS (Non-Access Stratum, non-access) layer for UE is set up.In the embodiment of the invention, can introduce a kind of new RRC message form, this RRC message comprises MBMS sign, MBMS request mark, one or more in the UE sign, thus form the RRC message that carries the MBMS solicited message.Thereby also can in existing RRC message, form a RRC message who can be used for showing the MBMS request by increasing the MBMS solicited message.
When adopting MAC CE mode to send, can adopt the LCID (Logic Channel Identifier) of agreement in the ascending resource that network side distributes, to send the MBMS solicited message.As shown in table 1, Index is the value of LCID, and LCID values represents the implication of the LCID of Index correspondence.For example agreement is used 11001 expression MBMS solicited messages in the reserved field (Reserved).Promptly when the middle discovery of UL-SCH (Uplink Shared Channel, Uplink Shared Channel) Logic Channel Identifier is 11001 MAC CE, then show among this MAC CE to comprise the MBMS solicited message.In addition, need increase the information of its bit number of indication for the MAC CE of carrying MBMS solicited message, specifically can directly indicate the bit number of this MAC CE, also can be by the number (because the bit number of each MBMS solicited message is fixed) of indicating the MBMS solicited message that comprises among the MAC CE, then by the bit number of number and each MBMS solicited message and the bit number of knowing MAC CE.
When adopting MAC SDU mode to send, can adopt the LCID of agreement in the ascending resource that network side distributes, to send the MBMS request message.As shown in table 2, for example agreement is used 11001 expression MBMS solicited messages among the Reserved.When finding in UL-SCH that promptly Logic Channel Identifier is 11001 MAC SDU, then show among this MAC SDU to comprise the MBMS solicited message.In addition, need increase the information of its bit number of indication for the MAC SDU of carrying MBMS solicited message, specifically can directly indicate the bit number of this MAC SDU, also can be by the number (because the bit number of each MBMS solicited message is fixed) of indicating the MBMS solicited message that comprises among the MAC SDU, then by the bit number of number and each MBMS solicited message and the bit number of knowing MAC SDU.

The invention provides a kind of MBMS requesting method, when UE request MBMS, UE sends random access sequence to network side, request inserts at random, after network side receives described random access sequence, for described UE distributes ascending resource, described UE sends the MBMS solicited message to network side in described ascending resource, network side responds described MBMS solicited message, replys MBMS request response to described UE, has solved the problem that does not have suitable MBMS request mechanism.
Below in conjunction with accompanying drawing, embodiments of the invention two are described.
In the embodiment of the invention, suppose the transmission that a certain sub-district has UE need ask a certain MBMS now, the process that the MBMS requesting method that uses the embodiment of the invention to provide is finished service request comprises as shown in Figure 2:
In this step, the UE that need carry out the MBMS request selects the Preamble sequence (random sequence) of a uplink random access, inserts on the resource of stipulating at uplink random then and sends to network side.When asking for MBMS, can fix some Preamble sequences in advance by network side is to use when being specifically designed to UE request MBMS.
In this step, network side detects the Preamble sequence that UE sends in step 201 after, for using the RA-RNTI sign in PDCCH, UE sends relevant information, described relevant information comprises at least: the Preamble sequence identifier that UE sends in the first step, Timing Alignment information (time queue information), initial UL grant (initial uplink mandate), Temporary C-RNTI (interim C-RNTI).Wherein uplink authorization information is to describe the ascending resource that network side distributes for UE in UL-SCH.
UE is then after step 201 is finished, beginning receives and retrieves the relevant information by the RA-RNTI sign in PDCCH, and whether by the Preamble sequence identifier in the described relevant information of further inspection is the own sequence that sends in the first step, if, UE confirms that then described relevant information is that network side sends to oneself so, otherwise UE abandons described relevant information.Continuation receives in PDCCH, detects, if a period of time (can realize being set at fixed value) does not also detect later, UE then restarts step 201 so.
On step 203, the UE ascending resource that network side distributes in step 202, send the MBMS solicited message to network side;
In this step, UE network side in step 202 is transmission MBMS solicited message in its ascending resource that distributes in UL-SCH.
In this step, the content of MBMS solicited message comprises the MBMS sign, can also comprise at least one in the following sign: MBMS request mark and UE sign.
Wherein, the MBMS sign is the service identification of the MBMS of this UE request, can be one or more.The MBMS request mark is to show that the information that this UE sends is the information that a request network side sends MBMS, rather than the information of other purposes.The UE sign is the identification information that is used for showing this UE identity, for example can be ue-Identity, perhaps S-TMSI, perhaps 40 bit value at random.
If adopt when passing through in standard agreement, to introduce new MBMS solicited message special RRC message, this moment, the MBMS solicited message comprised the MBMS sign so, wherein the UE sign can comprise also and can not comprise, do not need the MBMS request mark this moment, because new RRC message has been defined as the MBMS solicited message special use (identification information that contains sign RRC message in the RRC message, indicating this RRC message is to be used for asking MBMS's), network side can identify this new RRC message.
If employing increases the MBMS solicited message in existing RRC message after, promptly constituted the RRC message that is used for the MBMS request, the MBMS solicited message that needs to increase comprises MBMS sign and MBMS request mark (UE is designated optional, can comprise, and also can not comprise).For example, adopt existing RRCConnectionRequest message to carry the MBMS solicited message.Existing RRCConnectionRequest (RRC connection request) message is as follows:
RRCConnectionRequest?message
--ASN1START
RRCConnectionRequest::＝ SEQUENCE{
criticalExtensions CHOICE{
rrcConnectionRequest-r8 RRCConnectionRequest-r8-IEs，

Wherein, the MBMS request mark is to show that the purpose of the RRCConnectionRequestmessage of this transmission of UE is to carry out the MBMS request, wherein, comprises the MBMS sign of UE request, or MBMS sign and UE sign.
If adopt MAC CE or MAC SDU mode to send the MBMS solicited message, the MBMS solicited message that comprises that UE sends to network side specifically has: be used for identifying this MAC CE or MACSDU LCID and one or more MBMS solicited message of agreement in advance.Wherein the requested MBMS that comprises in the MBMS solicited message identifies, and this moment, the MBMS sign can be used the serviceId of MBMS, also can use other the information that shows MBMS, and wherein UE sign and MBMS request mark can comprise also and can not comprise.Wherein, the LCID of described agreement can not be placed among MACCE or the MAC SDU, only places the MBMS solicited message in MAC CE or MAC SDU.
The MBMS sign must have, and which MBMS that it indicates the UE request is.If not this information so network side can't know the MBMS of UE request.The MBMS request mark mainly acts on, show that to network side this purpose that sends information is to carry out the MBMS request, if the resource anxiety appears in network side, when also having other service needed Resources allocation of other high priorities simultaneously, network side can judgement according to this MBMS request mark after, be preferably other UE Resources allocation of high priority.The main effect of UE sign is that network side is used for judging whether this UE is legal, and whether this MBMS of authority request etc. is arranged.But can not need this UE sign for free MBMS, because broadcasting service generally is free, if sent also passablely, network side can know that some UE are interested for this MBMS at least.
In the embodiment of the invention, the RRC message that can also construct a special use sends the MBMS solicited message, network side can be known the type and the purpose of this RRC message according to the agreement regulation, because each RRC message of agreement regulation all has an identification information, it is that message that this identification information can help network side or UE to discern this message, thereby knows the implication and the purpose of this message Nepit.Adopt existing RRC message to send the mode of MBMS solicited message, network side can be known this RRC message type and the purpose of this moment by the MBMS request mark, thereby knows the implication of this message Nepit.Employing MACCE or MAC SDU mode send the MBMS solicited message, and network side can be known type and the purpose of this MAC CE or MAC SDU by arrange the LCID sign in advance in UL-SCH, thereby knows the implication of this data Nepit.
When using MAC CE or MAC SDU in UL-SCH, to send, need carry the LCID of prior agreement.As shown in table 1, be the distribution operating position of LCID among the UL-SCH among the LTE.In the embodiment of the invention, need distribute a LCID for MAC CE or the MAC SDU that the MBMS solicited message adopts.As shown in table 2, a value among the LCID that use LTE keeps is as the MAC CE of MBMS solicited message correspondence or the LCID of MAC SDU, for example using the LCID value that keeps originally is the LCID of the MAC SDU of 11001 MBMS solicited message, and the LCID value of distributing the back to keep is 01011-11000.When sending the MBMS solicited message with MAC CE or MAC SDU, the structure of MAC CE or MAC SDU can be carried a plurality of MBMS solicited messages as shown in Figure 3 simultaneously.
Because the MBMS solicited message can comprise the solicited message of one or more MBMS simultaneously, thus preferred, if use MAC CE mode, use length mark in the header of MAC CE, to show the bit length of MAC CE.Same, if use MAC SDU, use length mark in the header of MAC SDU, to show the bit length of MAC SDU.
Further, because the MBMS solicited message of a MBMS is fixed, the so during length mark of design MACCE or MAC SDU, can use the MBMS request number information that comprises among MAC CE or the MAC SDU, thereby bit length of informing MAC CE or MAC SDU indirectly.Can reduce signaling consumption like this.
Optionally, also can use the HARQ retransmission mechanism in this step, to increase system reliability.After UE sent the MBMS solicited message to network side, if network side is replied NACK (the expression network side does not correctly receive), UE need resend, if after repeatedly resending, when network side still can't correctly receive, UE restarted step 201.
In this step, after network side received the MBMS solicited message of this UE transmission, whether the network side decision sent the MBMS of this UE request, and asked the information of decision response (MBMSRequest Response) to reply to UE as MBMS.
For example, if the request of network side refusal UE need be replied the reason of refusal to UE, like this can be so that the user is known reason, thus promote user experience.If network side is accepted the request of UE, need to reply the relevant information of the MBMS of UE request so, for example the MBSFN area information of Fa Songing, stand-by period information etc. to UE.
Optionally, also can use the HARQ retransmission mechanism in this step, to increase system reliability.If UE does not still correctly receive the MBMS request response of network side after network side uses HARQ mechanism, UE restarts step 201 so.
