What is claimed is: 1. A method of receiving a point-to-multipoint service in a mobile terminal, the method comprising: receiving, in the mobile terminal, control information comprising a temporal offset, the control information being received from a current cell via a current cell point-to-multipo
What is claimed is: 1. A method of receiving a point-to-multipoint service in a mobile terminal, the method comprising: receiving, in the mobile terminal, control information comprising a temporal offset, the control information being received from a current cell via a current cell point-to-multipoint radio bearer information message or from a neighboring cell via a neighboring cell point-to-multipoint radio bearer information message; receiving, in the mobile terminal from the current cell, a first point-to-multipoint service transport block; calculating, in the mobile terminal, a connection frame number using the received temporal offset, wherein the temporal offset comprises one of a frame offset and a time offset; receiving, in the mobile terminal from the neighboring cell, a second point-to-multipoint service transport block using the calculated connection frame number, wherein the receiving of the second point-to-multipoint service transport block occurs while the first point-to-multipoint service transport block is received; and combining, in the mobile terminal, the first and second point-to-multipoint service transport blocks, wherein the point-to-multipoint service comprises a multimedia broadcast/multicast service. 2. The method of claim 1, wherein the control information comprising the temporal offset is received from a service radio network controller. 3. The method of claim 1, wherein the control information comprising the temporal offset is received via a radio resource control (RRC) signaling message. 4. The method of claim 1, wherein the control information comprising the temporal offset is received via one of a point-to-multipoint service control channel and a broadcast control channel. 5. A mobile terminal, comprising: an antenna unit adapted to receive RF signals comprising a first point-to-multipoint service transport block from a current cell, a second point-to-multipoint service transport block from a neighboring cell, and control information, wherein the control information is received from the current cell via a current cell point-to-multipoint radio bearer information message or from the neighboring cell via a neighboring cell point-to-multipoint radio bearer information message, the control information comprising a temporal offset, wherein the temporal offset comprises one of a frame offset and a time offset; an RF unit adapted to process the RF signals received by the antenna; a keypad for inputting information from a user; a storage unit adapted to store the first point-to-multipoint service transport block, the second point-to-multipoint service transport block, and the control information; a display adapted to convey information to the user; and a processing unit adapted to calculate a connection frame number using the temporal offset, process the first point-to-multipoint service transport block, process the second point-to-multipoint service transport block according to the calculated connection frame number, and combine the first and second point-to-multipoint service transport blocks, wherein the processing of the first point-to-multipoint service transport block occurs while the second point-to-multipoint service transport block is processed, wherein the point-to-multipoint service comprises a multimedia broadcast/multicast service. 6. The mobile terminal of claim 5, wherein the processing unit is further adapted to extract the control information comprising the temporal offset from a radio resource control (RRC) signaling message. 7. The mobile terminal of claim 5, wherein the processing unit is further adapted to process the control information comprising the temporal offset via one of a point-to-multipoint service control channel and a broadcast control channel. 8. A method of receiving a point-to-multipoint service in a mobile terminal, the method comprising: receiving, in the mobile terminal from a current cell, a first point-to-multipoint service transport block; receiving, in the mobile terminal from the current cell, first control information via a current cell point-to-multipoint radio bearer information message, the first control information comprising a first temporal offset; receiving, in the mobile terminal from a neighboring cell, second control information via a neighboring cell point-to-multipoint radio bearer information message, the second control information comprising a second temporal offset; calculating, in the mobile terminal, a connection frame number using at least one of the first temporal offset or the second temporal offset, wherein the temporal offset comprises one of a frame offset and a time offset; receiving, in the mobile terminal from the neighboring cell, a second point-to-multipoint service transport block using the calculated connection frame number, wherein the receiving of the second point-to-multipoint service transport block occurs while the first point-to-multipoint service transport block is received; and combining, in the mobile terminal, the first and second point-to-multipoint service transport blocks, wherein the point-to-multipoint service comprises a multimedia broadcast/multicast service. 9. The method of claim 8, wherein the first and second control information respectively comprising the first and second temporal offsets are received from a service radio network controller. 10. The method of claim 8, wherein the first and second control information respectively comprising the first and second temporal offsets are received via a radio resource control (RRC) signaling message. 11. The method of claim 8, wherein the first and second control information respectively comprising the first and second temporal offsets are received via a point-to-multipoint service control channel or a broadcast control channel. 12. The method of claim 1, wherein the first and second point-to-multipoint service transport blocks are received through a secondary common control physical channel (SCCPCH) mapped to a multimedia broadcast/multicast service traffic channel (MTCH). 13. The mobile terminal of claim 5, wherein the first and second point-to-multipoint service transport blocks are received through a secondary common control physical channel (SCCPCH) mapped to a multimedia broadcast/multicast service traffic channel (MTCH). 14. The method of claim 8, wherein the first and second point-to-multipoint service transport blocks are received through a secondary common control physical channel (SCCPCH) mapped to a multimedia broadcast/multicast service traffic channel (MTCH).
